Description

  The present invention relates to a slot machine that shifts to a gaming state advantageous to a player for a predetermined period in a game in which a result is determined by a combination of symbols displayed when a reel on which a plurality of symbols are drawn is stopped.

  Conventionally, a slot machine is widely known as one of gaming machines. In this type of slot machine, when the player inserts a prescribed number of game media such as medals and game balls, the operation of the start switch becomes effective. As a result, when the player operates the start switch, the game is started, the lottery is performed, and a plurality of reels each having a plurality of symbols are rotated. When the rotation speed of the reel reaches a certain speed, the operation of the stop switch provided corresponding to each reel becomes effective, and every time the player operates the stop switch, in accordance with the result of the role lottery, The corresponding reel is stopped, and when all reels stop, one game result is determined. And, if the combination of symbols displayed along the active line defined in the display window of the reel corresponds to some combination, it means that the combination is established, and the privilege corresponding to that combination Is given to the player, and one game is completed. On the other hand, when a combination is not established, one game is completed without a privilege being granted.

  In general, the above-mentioned combination includes a small combination, a re-playing role, and a special combination. When the small combination is established, a predetermined number of medals are paid out, and when the re-playing combination is established, As long as the special game is established, it is possible to play the game without inserting a game medium only for the next game. Special games can be played. In this special game, since the game play rate is set higher than games other than special games (hereinafter referred to as general games), the game state in which the special game is being performed is a player who can earn more medals. It can be said that this is an advantageous gaming state for the player.

  In recent years, a slot machine has appeared that can shift to a gaming state advantageous to a player even during a general game. As an example of this type of slot machine, for example, there is one that shifts to a so-called assist time (hereinafter referred to as AT) gaming state for a predetermined number of games. During this AT, when a specific small role is won in the role lottery, information related to the operation of the stop switch that can stop the symbol combination corresponding to the specific small role on the active line (for example, The player is informed of the symbols to be pressed and the operation sequence of the stop switch. Thereby, during AT, if a stop switch is operated in accordance with the notified information, a specific small role can be established. Therefore, by appropriately setting the winning probability of a specific small role in the role lottery, It is possible to create a gaming state that is advantageous for the player even during the game.

  Further, various proposals have been made regarding the transition conditions to the AT and the period of the AT. For example, in the slot machine described in Patent Document 1, when a re-game player is established three times continuously during a general game, the game machine shifts to AT. Further, in the slot machine described in Patent Document 1, when a predetermined number of games (30 games, 100 games, 200 games, 300 games, 500 games, 1000 games) are performed after shifting to AT. The continuous lottery for determining whether or not to continue the AT is performed. When it is determined that the AT is continued, the AT continues until the next predetermined number of games is performed. In addition, when a special role is established during AT and a transition is made to a special game, the counting of the number of games during the AT is stopped, and when the special game is completed, counting of the number of games during the AT is resumed.

Japanese Patent Laid-Open No. 2003-070970

  As described above, in the slot machine described in Patent Document 1, when shifting to the AT, since the AT is reliably maintained until a predetermined number of games are performed, it is possible to give the player a sense of security. it can. In addition, when a predetermined number of games have been performed, it is possible to improve the interest related to the game by giving a sense of tension as to whether or not the AT continues by performing a continuous lottery. In addition, if the game shifts to a special game during the AT, the number of games during the AT will be stopped during that time, and the special lottery will not be accelerated as a result of the special game, giving the player a sense of loss. There is also an advantage that there is no.

  However, in the slot machine described in Patent Document 1, when the game shifts to the special game during the AT, the number of games during the AT is stopped during that time, but this is only due to the shift to the special game. , Measures to avoid a reduction in the benefits that would otherwise be provided by the AT. For this reason, even if a special game is played during AT, there is an advantage that the player is not given a sense of loss related to profits from AT, but there is no expectation for the increase in profits brought by AT. .

  In addition, if it is determined that the AT will continue as a result of the continuous lottery, the AT will surely continue until the number of games in which the next continuous lottery is performed. There were few elements to improve the fun of the game, such as giving the player a sense of tension.

  The present invention has been made in view of the above-mentioned problems, and has an expectation for an increase in profits that can be enjoyed by the advantageous gaming state even after shifting to a gaming state advantageous to the player during a general game. It is also an object of the present invention to provide a slot machine that can give a sense of expectation and tension as to how much the profit from an advantageous gaming state increases.

In order to solve the above-described problems, according to the present invention, when a predetermined number of game media are inserted, a plurality of reels each displaying a plurality of types of symbols can be rotated, and the plurality of reels are rotated. A slot machine for performing a game that gives a player a privilege corresponding to the combination corresponding to the symbol combination displayed when all of them are subsequently stopped,
A role lottery means for performing a role lottery in which one of a plurality of types of roles is determined as a winning role;
A plurality of stop instruction means provided corresponding to each of the plurality of reels and instructing rotation stop of the corresponding reels according to an operation from the outside;
When any one of the plurality of stop instructing means is operated, the operated stop is performed so that the symbol combination corresponding to the winning combination determined in the combination lottery is stopped and displayed according to the operated timing. Reel stop control means for performing reel stop control for stopping rotation of the reel corresponding to the instruction means;
When a predetermined start condition is satisfied, a specific game period that is advantageous to the player is started, and the specific game period is ended according to the number of times the game has been executed during the specific game period. Control means;
In a game during the specific game period, when a predetermined combination is determined as a winning combination in the combination lottery, specific game execution means for performing a specific game advantageous to the player;
Informing means for informing information relating to the number of times the game has been executed during the specific game period;
In the game during the specific game period, an extension period determining means for determining an extension period for extending the specific game period according to the type of the winning combination determined in the combination lottery,
The gaming state control means includes
When the extension period determining means determines the extension period, the specific game period is ended when the number of times of the end game and the game of the extension period are performed.

  Here, the “specific game period” corresponds to, for example, an AT, and when the “predetermined small role” is won in the role lottery during the “specific game period”, the “specific game execution means” The “specific game advantageous to the player” is performed. That is, the “specific game advantageous to the player” is, for example, information related to the operation of “a plurality of stop instruction means” capable of establishing the “predetermined small combination” won in the combination lottery. It is a game. Further, the “extension period” may be determined by the number of games or may be determined by time.

  In the slot machine according to the present invention, when a predetermined start condition is satisfied, a specific game period starts. During this time, when a predetermined small role is won in the lottery, a game advantageous to the player is performed. In addition, during the specific game period, the specific game period is extended depending on the type of the winning combination in the combination lottery, so that an opportunity for a game advantageous to the player is increased. As a result, even during the specific period, it is possible to expect an increase in profits obtained by playing a game advantageous to the player.

Further, in the slot machine described above, when the extension period is determined by the extension period determination means, the notification unit displays information on the number of executions while the game of the extension period is being performed. Instead of notifying, the extension determination information indicating that the extension period has been determined is notified, and
When a game in the extension period is performed after the extension period is determined, information on the number of executions is notified instead of the extension determination information.

  In the slot machine according to the present invention, when the extension period of the specific game period is determined, information indicating that the extension period has been determined instead of the information related to the number of game executions during the specific game period that has been informed so far Is notified. And when the game of the determined extension period is performed, the information regarding the original number of game executions is displayed again. At this time, the information related to the number of game executions displayed again is resumed from the information related to the number of game executions notified until immediately before the extension period starts. That is, the content does not reflect the number of game executions performed during the extension period. In this way, by not telling the player how long the specific game period is extended (time or number of games), when the extended period ends in the game during the extended period, There is a possibility that the player can have an appropriate feeling of tension, and as a result, there is a possibility that the interest of the game can be improved.

Further, the present invention is the slot machine described above, wherein the extension period determining means performs a lottery to select one from a plurality of predetermined different number of games, and determines the number of games selected by the lottery. As an extension period,
The informing means performs the same number of games as the number of games not selected by the extension period determining means while the selected number of games are being played after the extension period is determined. In addition, the player is notified that there is a possibility that the extension period has ended.

  Here, the “number of unselected games” in which the notification means may notify that the extension period may have ended is less than “the number of selected games” among “a plurality of different number of games”. Needless to say, the number of times.

  In the slot machine according to the present invention, the extension period is determined by selecting any one of the plurality of game times, and in the game during the extension period, the game number not selected among the plurality of game times If the same number of times is performed, a notification is made that the extension period may have ended. Thereby, there is a possibility that the interest of the game can be improved by providing a knot during the extension period and giving the player a moderate tension at the knot.

In addition, in any one of the slot machines described above, the present invention provides a plurality of types of small roles for paying out a predetermined number of game media as benefits to the plurality of types of roles, and predetermined as benefits. A special combination capable of playing a special game that makes it easy to display a symbol combination corresponding to the small combination when the plurality of reels are all stopped until a given end condition is satisfied,
The combination lottery means, in a single combination lottery, when a specific small combination is determined as a winning combination among the plurality of types of small combinations, and when both the specific small combination and the special combination are determined as a winning combination And
The extension period determining means uses the symbol combination displayed when all of the plurality of reels are stopped in the game in which only the specific small combination is determined as the winning combination in the combination lottery during the specific game period. Determine the extension period according to the corresponding probability,
When the plurality of reels are all stopped in the game in which only the specific small combination is determined to be a winning combination in the combination lottery and the game when the special combination is determined to be a winning combination. When a specific symbol combination is displayed, whether the special combination is determined as the winning combination in the combination lottery or whether the extension period is determined by the extension period determination means with a predetermined probability. It is characterized by notifying.

  In the slot machine according to the present invention, in a game during a specific game period, when only a specific small role is won in the role lottery, the extension period is determined with a probability corresponding to the symbol combination stopped and displayed in the game. In addition, when only a specific small role is won in a role lottery during a specific game period (in this case, the extension period is determined with a probability corresponding to the symbol combination that is stopped and displayed), and a specific small size If a specific symbol combination is stopped and displayed when both the combination and the special combination are won, it is notified with a predetermined probability whether the special combination has been won or whether the extension period has been determined. As a result, when a specific symbol combination is stopped and displayed in a game during a specific game period, there is a possibility that notification advantageous to the player may be performed, so that the player's expectation may be increased.

  As described above, according to the slot machine of the present invention, it is possible to have an expectation for an increase in profits that can be enjoyed by the advantageous gaming state even after shifting to a gaming state advantageous for the player during the general game, Moreover, expectation and a feeling of tension can be given to how much the profit by an advantageous gaming state increases.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
An appearance of the slot machine 10 according to the present embodiment is shown in FIG. FIG. 1 is a front view of the slot machine 10. In FIG. 1, a front panel 20 is provided on the front surface of the casing of the slot machine 10. A display window 22 is formed substantially at the center of the front panel 20, and symbols printed on the outer peripheral surfaces of the three reels 40L, 40C, and 40R that are rotatably provided inside the slot machine 10 are displayed. Is displayed. Each of the reels 40L, 40C, and 40R is provided such that the respective rotation axes are arranged on the same straight line in the horizontal direction, each having a ring shape, and 21 symbols are printed at equal intervals on the outer peripheral surface thereof. A strip of reel tape is affixed. From the display window 22, when the reels 40L, 40C, and 40R are stopped, among the 21 symbols printed on each reel, three symbols that are continuous along the rotation direction of each reel are visually recognized. It is possible. That is, 3 [symbol] × 3 [reel] = 9 symbols in total are stopped and displayed on the display window 22. Here, among the three consecutive symbols displayed when the reels 40L, 40C, and 40R are stopped, the uppermost stop display position is the upper stage U, the middle stop display position is the middle stage M, and the lowermost figure. The stop display position is set to the lower stage L.

  The display window 22 has five pay lines that cross the reels 40L, 40C, and 40R. In the display window 22, the five winning lines are a V-shaped winning line L1 passing through the upper stage U of the left reel 40L, the middle stage M of the middle reel 40C, and the upper stage U of the right reel 40R, and the left reel 40L. The lower stage L, the middle stage M of the middle reel 40C, and the diagonally upward winning line L2 passing through the upper stage U of the right reel 40R, the middle stage horizontal prize line L3 passing through the middle stage M of each reel, and the left reel 40L The upper U stage, the middle stage M of the middle reel 40C, and the lower stage L of the right reel 40R are slanted to the lower right, and the lower stage L of the left reel 40L, the middle stage M of the middle reel 40C, the lower stage L of the right reel 40R. Yamagata winning line L5. Thus, each winning line passes through any one of the three stop display positions (upper U, middle M, and lower L) of the reels 40L, 40C, and 40R.

  Each of the winning lines L1 to L5 is a reference line for determining a combination of symbols corresponding to a plurality of predetermined types (described later), and when the reels 40L, 40C, and 40R are stopped, Of the five winning lines, a combination of three symbols each stopped and displayed at a stop display position through which a winning line deemed effective (hereinafter referred to as an effective line) passes corresponds to one of the roles. Sometimes the role is established.

  In addition to the display window 22, the front panel 20 is provided with various lamps and a display for notifying the player of various information related to the game. First, on the left side of the display window 22, operation instruction lamps 24L, 24C, and 24R are provided in order from the top in FIG. These operation instruction lamps 24L, 24C, and 24R are for instructing the player the operation order of stop switches 37L, 37C, and 37R described later when the reels 40L, 40C, and 40R are rotating. That is, the left stop switch 37L is operated when the operation instruction lamp 24L is lit, the middle stop switch 37C is operated when the operation instruction lamp 24C is lit, and the right stop switch 37R is operated when the operation instruction lamp 24R is lit. Indicates that it should be.

  Below the display window 22, bet number (betting number) display lamps 26 a, 26 b, 26 c, a credit number display 27, and an acquired number display 28 are provided in order from the left in FIG. 1. The bet number display lamps 26a, 26b, and 26c are for displaying the number of medals inserted in one game. That is, when one medal is inserted, only the bet number display lamp 26a is lit, and when two medals are inserted, the bet number display lamps 26a and 26b are lit and three medals are inserted. The bet number display lamps 26a, 26b, and 26c are turned on. Here, the slot machine 10 is a so-called three-sheet betting machine in which one game can be performed by inserting three medals and the winning lines L1 to L5 are all active lines. The credit amount indicator 27 is a two-digit 7-segment indicator, and displays the number of medals credited (stored) in the slot machine 10 (more specifically, stored in the RAM 110 described later). . The acquired number display 28 is a two-digit 7-segment display, and displays the number of medals to be paid out to the player in the slot machine 10 according to the game result.

  A substantially horizontal operation panel unit 30 is provided below the front panel 20 described above. A medal slot 32 for inserting medals into the slot machine 10 is provided on the upper right side of the operation panel 30. A medal sensor (not shown) is provided inside the medal insertion slot 32. When a medal inserted from the medal insertion slot 32 is detected, a medal detection signal is output. By counting the number of outputs of the medal detection signal, the number of inserted medals can be recognized. A 1-bet switch 34 and a maximum bet switch 35 that can insert credited medals into the slot machine 10 are provided on the upper left side of the operation panel 30. The 1-bet switch 34 is a switch for inserting only one medal that is credited every time it is operated into the slot machine 10 as a game betting target. The maximum bet switch 35 is a switch for inserting three of the credited medals into the slot machine 10 as a game betting target.

  When three medals are inserted into the slot machine 10 from the medal insertion slot 32 or by operating the various bet switches 34 and 35, the bet number display lamps 26a, 26b and 26c are sequentially displayed every time a medal is inserted. The winning lines L1 to L5 become effective lines. Further, when medals are inserted by operating the various bet switches 34 and 35, the number of inserted medals is subtracted from the number of credits stored in the RAM 110, which will be described later. The value displayed in 27 is also subtracted. When a prescribed number (three) of medals have already been inserted, and further medals are inserted from the medal insertion slot 32, the number of inserted medals is added to the number of credits stored in the RAM 110. And is added to the value displayed on the credit amount display 27.

  A start switch 36 is tiltably provided on the left side of the front surface of the operation panel unit 30. When the player inserts a prescribed number (three) of medals into the slot machine 10 and then tilts the start switch 36, the three reels 40L, 40C and 40R described above start to rotate all at once. As a result, the symbols printed on the outer peripheral surfaces of the reels 40L, 40C and 40R are moved (scrolled) from the top to the bottom in the display window 22. Three stop switches 37L, 37C, and 37R are provided at the front center portion of the operation panel 30. Here, the left stop switch 37L corresponds to the left reel 40L, the middle stop switch 37C corresponds to the middle reel 40C, and the right stop switch 37R corresponds to the right reel 40R. The stop switches 37L, 37C, and 37R are operated by the player when the rotation speeds of the three reels 40L, 40C, and 40R reach a predetermined steady rotation speed (for example, 80 rotations / minute).

  When the player pushes the left stop switch 37L, the left reel 40L stops. When the middle stop switch 37C is pushed, the middle reel 40C stops and the right stop switch 37R is pushed. Sometimes the right reel 40R stops. At this time, each of the three reels 40L, 40C, and 40R has the center position of any three consecutive symbols out of the symbols drawn on the outer peripheral surface of each reel, the upper U in the display window 22, Stop control is performed so as to be positioned at the center of each of the middle stage M and the lower stage L. Here, a position where the center of the symbol coincides with the center of the stop display position is referred to as a fixed position. In the slot machine 10, when the player operates the stop switch to stop the corresponding reel, reel stop control is performed so that the symbol always stops at a fixed position.

  A lower panel 50 on which a model name of the slot machine 10 and characters adopted as a motif are drawn is disposed below the operation panel 30. A medal payout opening 60 for paying out medals to the player is provided at a substantially lower center of the lower panel 50. That is, when the reels 40L, 40C, and 40R are stopped and the combination of the three symbols stopped and displayed along the active line corresponds to the small role, the hopper (inside the slot machine 10) (Not shown) is activated and the number of medals corresponding to the small combination is paid out. Then, the paid-out medals are discharged from the medal payout outlet 60 and stored in the tray 61. On the right side and the left side of the medal payout opening 60, sound transmission holes 62R and 62L are provided for allowing sounds emitted from speakers 64R and 64L (described later) housed inside the slot machine 10 to pass outside.

The display device 70 displays a game history, an effect image displayed during a special game, an effect image for notifying the result of a role lottery, a game progress (medal insertion → operation of the start switch 36 → reel It is possible to display an effect image or the like according to (rotation → operation of stop switches 37L, 37C, 37R → all reel rotation stop). Above the display device 70, there is provided an upper effect lamp 72 that blinks in a pattern corresponding to the established combination when the reels 40L, 40C, 40R are stopped and any combination is established.

  Next, with reference to FIG. 2, the arrangement of symbols printed on the reel tape attached to the outer peripheral surfaces of the reels 40L, 40C and 40R will be described. As described above, 21 symbols are printed on the outer peripheral surfaces of the reels 40L, 40C, and 40R. One design is printed. In addition, there are ten types of symbols displayed in each symbol display area, and a type code (not shown) is predetermined according to each type. The types of symbols in this embodiment are the “red 7” symbol, the “blue 7” symbol, the “7” symbol representing the number 7 in red and blue, the “BAR” symbol with a bar-like lump motif, and the cherry motif. "Red cherry" design, "Blue cherry" design, "Black cherry" design, and "Watermelon" design with watermelon motif, and "Bell" design with bell motif There are a “plum” design using a plum as a motif and a “character” design depicting a predetermined character.

  In addition, symbol numbers “1” to “21” are predetermined in each symbol display area of the reel tape attached to each of the reels 40L, 40C, and 40R. As shown in FIG. The number is associated with a symbol type code printed in the symbol display area corresponding to the symbol number, and stored in the ROM 108 described later. These pieces of information are referred to when the slot machine 10 identifies symbols displayed at each stop display position (upper U, middle M, lower L) of the display window 22. Hereinafter, the symbol number and the type code are collectively referred to as symbol identification information. When the reel tapes having the contents shown in FIG. 2 are attached to the outer peripheral surfaces of the corresponding reels 40L, 40C, and 40R, the symbols of the symbol numbers “1” and “21” are continuous in the symbol array of FIG. become.

The control program stored in the ROM 108 includes a main routine shown in FIG. 18 and programs for executing various subroutine processes shown in FIGS.

  A RAM 110 is also connected to the input / output bus 104, and the CPU 106 refers to various flags (for example, a winning flag corresponding to various roles described later, a re-game establishment flag, etc.) referred to in the course of performing the above-described control program processing. ) And values of variables (values such as symbol numbers displayed on the display window 22, number of medals inserted, number of credits, number of medals paid out, number of games in various gaming states, etc.) are temporarily stored. The RAM 110 also stores game state information indicating the game state of the slot machine 10. The game state information includes information indicating four game states of “general game”, “RB game”, “BB game”, and “SRB game”, and an RT state (“non-RT” / “ RT1 ”/“ RT2 ”/“ RT3 ”). In the slot machine 10, processing relating to selection of the winning lottery table and transition between the game states is performed in accordance with these game states. Each gaming state described above will be described in detail later.

  Various information input to the CPU 106 includes signals output from the 1-bet switch 34, the maximum bet switch 35, the start switch 36, and the stop switches 37L, 37C, and 37R shown in FIG. Is input to the CPU 106 via the interface circuit 102 connected to the input / output bus 104. Further, the information input to the CPU 106 includes a random number (integer) generated within a numerical range of 0 to 65535 (2 to the 16th power) by the random number generator 112, and this random number is transmitted via the input / output bus 104. Are input to the CPU 106. Instead of generating a random number by the random number generator 112, a random number may be generated by a calculation process of the CPU 106.

  The CPU 106 controls various devices connected to the input / output bus 104 according to the result of processing the various control programs described above. First, the CPU 106 outputs a driving pulse to the motor driving circuit 114, and performs rotation control of the stepping motors 80L, 80C, and 80R. Each of the stepping motors 80L, 80C and 80R is provided on the inner peripheral side of the three reels 40L, 40C and 40R, and the rotation centers of the reels 40L, 40C and 40R are attached to the rotation shafts of the stepping motors 80L, 80C and 80R. ing. The motor drive circuit 114 is connected to the stepping motors 80L, 80C, and 80R, and rotates each stepping motor one step each time a drive pulse is output from the CPU 106. Further, the CPU 106 transmits various types of information related to games in the slot machine 10 (details will be described later) to the sub-control circuit 200 described below through the connection line 118 via the interface circuit 102.

≪Description of sub control circuit≫
Next, the configuration of the sub control circuit 200 will be described with reference to FIG. The connection line 118 described above is connected to the interface circuit 202 connected to the input / output bus 204 of the sub control circuit 200. Various types of information transmitted from the main control circuit 100 to the sub control circuit 200 are converted into predetermined signals by the interface circuit 202, supplied to the input / output bus 204, and temporarily stored in the RAM 210. The input / output bus 204 is configured to input / output data signals or address signals to / from the CPU 206. The input / output bus 204 is also connected with a ROM 208, a RAM 210, a lamp driving circuit 218, a display driving circuit 220, and a speaker driving circuit 222.

  The ROM 208 stores a control program for controlling the lamp driving circuit 218, the display driving circuit 220, and the speaker driving circuit 222, and initial data for executing the control program. The ROM 208 also stores various image data to be displayed on the display device 70, performance sound data to be emitted from the speakers 64L and 64R, pattern data for blinking the upper effect lamp 72, and the like. Further, the ROM 208 stores a control program (see FIGS. 25 to 28) for controlling various notifications and effects described later. In addition, during the ART game, a lottery table (see FIG. 12) for determining the number of games to be added to the number of ART games is also stored.

  In the RAM 210, in addition to various data generated / fluctuated in the process of executing the various control programs described above, on / off states of flags, stop switches operated as a result of the role lottery transmitted from the main control circuit 100 Various information such as information indicating the game state, the game result, the current game state / RT state, and the transition information indicating whether or not to shift to the ART game period (see FIG. 13) are also stored.

  The lamp driving circuit 218 lights / flashes the operation instruction lamps 24L, 24C, 24R and the upper effect lamp 72 in accordance with driving commands output from the CPU 206 based on various information signals supplied from the main control circuit 100. . The display driving circuit 220 causes the display device 70 to display image data, character data, and the like read from the ROM 208 by the CPU 206 based on the information signal supplied from the main control circuit 100. Thereby, on the display device 70, image data is displayed as an effect screen, or character data is displayed as a character message. The speaker drive circuit 222 drives the speakers 64R and 64L according to the audio data read from the ROM 208 by the CPU 206 based on the information supplied from the main control circuit 100, and the audio is transmitted from the sound transmission holes 62R and 62L shown in FIG. Is output.

[Explanation of functional block diagram]
Next, a functional block diagram of the control circuit of the slot machine 10 is shown in FIG. In the following description, the same components as those shown in FIGS. 1 and 3 are denoted by the same reference numerals, and detailed description thereof is omitted. First, there are a main control circuit 100 and a sub-control circuit 200 as control circuits, and both are electrically connected. The main control circuit 100 is electrically connected to the operation means 300 and the motor drive circuit 114. The sub-control circuit 200 is electrically connected to a notification output means 600 including speakers 64L and 64R, a display device 70, an upper effect lamp 72, and operation instruction lamps 24L, 24C and 24R. The operation unit 300 includes a rotation instruction unit 310 including a start switch 36 and a stop instruction unit 320 including three stop switches 37L, 37C, and 37R. The operation means 300 is not limited to a switch, and any means can be applied as long as it generates an operation signal based on an operation using the limbs of the player. In addition, the notification output means 600 is not limited to a device that provides auditory and visual notification of a player such as sound and light. For example, a vibration generating device such as a vibrator is provided inside the slot machine 10 to specify a specific part. You may make it perform the alerting | reporting recognized by a player's tactile sense by vibrating.

≪Description of main control circuit≫
The main control circuit 100 includes a combination lottery means 410, a reel control means 420, a winning determination means 430, and a winning processing means 440. The role lottery means 410 determines whether or not one or more of the predetermined roles are won by performing the role lottery. The predetermined roles described above are roughly classified into three types: small roles, replay (also called replay) roles, and bonus roles (special roles). A small combination is a combination in which a predetermined number of medals are paid out to the player when established, and a plurality of types of small combinations are determined according to corresponding symbol combinations. When a re-game is established, the game can be played again without inserting medals only for the next game. The game that can be played again is called replay (replay), and the effective line in the replay is the same as the effective line in the game in which the replaying role is established.

  When the bonus combination is established, a special game that is highly likely to be able to acquire medals in each game is started from the next game until a predetermined end condition is satisfied. The special games in the slot machine 10 include a big bonus game (hereinafter referred to as BB game) and a regular bonus game (hereinafter referred to as RB game) depending on the end conditions. In the BB game, when the number of medals paid out exceeds a predetermined number (here, 300), the end condition is satisfied, and the game returns to the game (general game) before the transition to the special game. Also, in the RB game, when the game is played a predetermined number of times (for example, 12 times) or the number of times the small role is won reaches a predetermined number of times (for example, 8 times), the RB game end condition is satisfied and the game returns to the general game.

  An RB game may be played even during a BB game, and the RB game at this time is particularly called an SRB game. This SRB game is started when the SRB combination is established during the BB game, and basically returns to the BB game when the termination condition of the SRB game is established. However, when the termination condition of the BB game is satisfied during the SRB game. Returns to general games. Hereinafter, in the BB game, when a game state that is not an SRB game is particularly distinguished, it is referred to as a general game during BB.

<Description of role lottery means>
The role lottery means 410 includes, for example, a random number generator 112 (hard random number or the like) shown in FIG. 3, a random number extraction means 412 that extracts a random number generated by the random number generator 112, and a random number extracted by the random number extraction means 412. Random number determination means 414 is provided for determining the presence / absence of a winning combination and the winning combination by comparing a numerical value with a winning lottery table stored in the ROM 108. The control processing by the role lottery means 410 is shown in a role lottery processing subroutine (see FIG. 19) described later. Here, with reference to FIG. 6, the types of winning combinations that can be established in the slot machine 10 will be described. FIG. 6 shows the contents of the payout information in which the name of each winning combination, the symbol combination that will result in the winning combination, and the number of medals to be paid out to the player when the winning combination is established. This payout information is stored in the ROM 108 of the main control circuit 100 shown in FIG.

  As shown in FIG. 6, each combination that can be realized in the slot machine 10 is associated with a symbol combination including symbols drawn on the left reel 40L, the middle reel 40C, and the right reel 40R. This symbol combination means a symbol combination that is stopped and displayed along any one of the effective lines L1 to L5, and is referred to when the winning determination means 430 described later makes a winning determination. Moreover, when these symbol combinations are stopped and displayed along the active line, the corresponding combination is established, and a privilege corresponding to each combination is given to the player.

  That is, when the BB combination is established, the above-described BB game is started from the next game, and when the SRB combination is established in the general game during BB, the above-described SRB game is started from the next game as a privilege. Further, when a re-game is established, the next game becomes a re-game as a privilege. When a small combination is established, the number of medals corresponding to the type of the small combination established as a privilege is paid out to the player. More specifically, when a small combination 1 is established, one medal is paid out, and when any of the small combinations 2a to 2c is established, nine medals are paid out and a small combination 3 is established. In this case, 6 medals are paid out. Here, the formation of a combination in which medals are paid out as a small combination is also called winning.

  Next, the contents of the winning lottery table stored in the ROM 108 will be described with reference to FIGS. First, in FIG. 7, (a) shows the contents of the role lottery table used when the game state is a general game and the RT state is “RT1”. (B) shows the contents of the role lottery table used when the game state is a general game and the RT state is “RT3”. FIG. 8 shows the contents of the role lottery table used when the game state is a general game and the RT state is “non-RT” and “RT2”. Here, in the combination lottery table shown in FIG. 8, when the RT state is “non-RT” and “RT2”, the difference is that the numerical range of the lottery result number “22” is “non-RT”. Becomes 108 to 6375, and when “RT2”, 107 to 6375 (see FIG. 8B). FIG. 9 shows the contents of the role lottery table used when the game state is a special game (BB game, RB game or SRB game), and (a) is used for RB game or SRB game. The role lottery table, (b) shows the content of the role lottery table used in the BB game (except during the SRB game).

  The role lottery table associates random values (0 to 65535) that can be generated by the random number generator 112 with the lottery results, and the random number determination unit 414 uses the random number extracted by the random number extraction unit 412 as the random number value. A lottery result (lottery result number) is derived depending on which numerical range of the combination lottery table belongs. The combination corresponding to the derived lottery result number is the combination won in the combination lottery (winning combination). However, if the lottery is associated with the derived lottery result number, it means that no winning combination has been won. A value obtained by dividing a numerical range (numerical value) corresponding to each lottery result number by 65536 is a probability that each lottery result number is derived (synonymous with the winning probability of each combination).

  For example, in the case of the lottery table shown in FIG. 7A, if the extracted random number is a value included in the range of “0” to “41840”, the lottery result number “12” is derived, The result of the lottery will be lost. If the extracted random number is a value included in the range of “41841” to “50819”, the lottery result number “11” is derived, and the result of the winning combination lottery is the winning of the re-playing player a. . When a lottery result number associated with a plurality of combinations is derived, all the associated combinations are won. For example, in the combination lottery table shown in FIG. 7A, when the extracted random number is a value included in the range of “51478” to “55845”, the lottery result number “9” is derived, 2a, small part 2b and small part 2c are elected.

  As a result of the lottery, when a certain winning combination is won, the flag corresponding to the winning combination (hereinafter referred to as a winning flag) is turned on (“1”) by the random number determination means 414. The on / off state of the winning flag corresponding to each combination is stored in the RAM 110 shown in FIG. When one game is completed, if a winning flag corresponding to either the re-playing winning combination or each small winning combination is turned on by winning determination means 430 described later, a winning combination corresponding to the winning flag is displayed. Regardless of whether or not it is established, the winning flag is turned off. On the other hand, if the winning flag of any one of the BB combination a, the BB combination b, and the RB combination is turned on during the general game, the combination is established even if the game ends. The ON state is maintained until. Thus, the state where the ON state of the winning flag is maintained is also referred to as “carrying over the bonus flag”.

  Further, in a game in which the bonus flag is carried over, if any small role or re-playing role is won in the winning lottery, the winning flag corresponding to the winning role is turned on. Therefore, the winning flag corresponding to each winning combination at this time is the ON state corresponding to the winning combination in the winning lottery and the special winning combination in which the ON state is held. Furthermore, in a game in which the bonus flag is carried over, when any special combination is won, the winning flag corresponding to the special combination is not turned on. Therefore, the plurality of winning flags corresponding to the special combination are not turned on in parallel.

  Next, in the combination lottery tables shown in FIGS. 9A and 9B, the lottery result numbers are not associated with the BB combination and the RB combination. Therefore, during the RB game, the SRB game, and the BB game (more specifically, the general game during the BB), the BB combination or the RB combination is not won. Also, as shown in FIG. 9 (a), during the RB and SRB games, the combined winning probability of the small roles 1, 2a and 3 is very high at about 1 / 1.01. It can be said that the game state is advantageous for the player during the SRB game. Furthermore, in the general game in BB, as shown in FIG. 9B, the combined winning probability of the small roles 1, 2a to 2c, 3 is not different from that in the general game (about 1 / 4.52), but the SRB The winning probability of the combination is set as high as about 1/3. For this reason, it can be said that the general game during BB is also in a gaming state advantageous to the player.

  Next, the combination lottery table for “non-RT” and “RT2” shown in FIG. 8 will be described. As shown in FIG. 8A, in the above-described combination lottery table in each RT state, the types of combinations respectively associated with the lottery result numbers “1” to “10” and the lottery result numbers are associated with each other. The obtained numerical range is exactly the same as the role lottery table for “RT1” and “RT3” shown in FIG. However, for re-games, in the role lottery table shown in FIG. 7, only one type of re-game player can be won in one role lottery table, whereas in the role lottery table shown in FIG. In the table, the contents are such that a plurality of types of re-game players can be won at the same time. That is, any one of the re-game players a to f (see FIG. 6) can be won simultaneously, and specifically, as shown in FIG. 8 (b). In this figure, for each of the lottery result numbers “11” to “22”, the re-playing combination that can be won at the same time is indicated by “◯”. For example, when the lottery result number “11” is derived, the re-players a, c, d are simultaneously won, and when the lottery result number “12” is derived, the re-players a, c, e are You will be elected at the same time.

  Further, in the combination lottery table for “RT1” and “RT3”, the (combined) winning probability of the re-game combination is about 1 / 7.3, whereas for “non-RT” and “RT2” In the role lottery table for use, it is about 1 / 1.29. Therefore, it can be said that any re-game player is easily won when the general game is in progress and the RT state is “non-RT” or “RT2”.

  Returning to FIG. 5, the random number determination means 414 selects a role lottery table corresponding to the current game state and the RT state during the general game from the role lottery tables shown in FIGS. 7 to 9. The winning combination is determined based on the random number value extracted by the random number extracting means 412 and the selected combination lottery table.

<Description of reel control means>
The reel control unit 420 includes a reel stop control unit 422, and performs control related to rotation driving of the reels 40L, 40C, and 40R. That is, when the reel rotation start signal transmitted from the start switch 36 is received, the stepping motors 80L, 80C, and 80R are driven via the motor drive circuit 114. Thus, after the reels 40L, 40C, and 40R are rotated, when a reel stop signal is transmitted from the stop switches 37L, 37C, and 37R, the reel stop control means 422 causes the reel stop control to be performed.

  When a reel stop signal is transmitted from the stop switches 37L, 37C, and 37R, the reel stop control unit 422 stops the rotation of the reel corresponding to the operated stop switch within 190 milliseconds. In other words, assuming that the steady rotation speed is 80 revolutions / minute and the number of symbols per reel is 21, the reel stop control means 422 determines at most 5 symbols from the rotational position of the reel when the stop switch is operated. Until the turn, the symbols constituting the symbol combination corresponding to the winning combination (refer to FIG. 6) (hereinafter referred to as the winning symbol) the stop display position through which the effective line passes (hereinafter referred to as the effective line) If the winning symbol reaches the position of the active line, the reel is stopped. Here, the rotation position of the reel means the position in the rotation direction of the reel (for example, when the position when the symbol of symbol number “21” is at the fixed position of the middle stage M is used as the reference position, Position). In addition, when another reel is already stopped and the winning symbol of that reel is stopped at the position of any effective line, the winning symbol of the reel to be stopped is the position of that effective line. After moving (turning) within the above range so as to stop, the reel is stopped. For example, when the winning symbol on the left reel 40L is stopped at the upper stage U and the stop control of the right reel 40R is performed, the winning symbol on the right reel 40R is set to the upper stage U (position of the effective line L1) or the lower stage L. Of the (position of the effective line L4), it is stopped to either one that can be stopped.

  On the other hand, if the winning symbol cannot be reached at the position of the effective line even if the corresponding reel is rotated by 5 symbols, an appropriately determined symbol between the 5 symbols is rotated. The reels are stopped so that they are displayed in a stopped state (however, a certain combination is not established). In this case, even if any combination is won in the combination lottery, the combination of symbols corresponding to the combination is not stopped and displayed along the active line, so that combination is not established. Hereinafter, such a game result is referred to as “missing”.

  Here, when the symbol arrangement of each reel shown in FIG. 2 is considered on the premise of the above-described reel stop control, the “bell” symbol and the “plum” symbol in each reel indicate what kind of stop switch is selected from the arrangement interval. Even if it operates with timing, it can be stopped in any of the upper stage U, middle stage M, and lower stage L. In the right reel 40R, the “watermelon” symbol is the same. For this reason, according to the payout information shown in FIG. 6, the small combination 2a (design combination: bell-bell-bell), re-playing combination a (design combination: plum-plum-plum), re-playing combination b (design combination) : Plum-Plum-Watermelon), Re-playing role c (Pattern combination: Plum-Plum-Bell) and SRB role (Pattern combination: Bell-Plum-Watermelon) There is no spillage. On the other hand, for combinations other than the combinations described above, even if the reel stop control described above is performed, the combinations include symbols that cannot be stopped at the position of the effective line depending on the operation timing of the stop switch. ing. In other words, there is a possibility of missing.

  In addition, when the result of the lottery is lost, the reel stop control means 422 causes the symbol combination corresponding to any combination to follow the active line regardless of the timing of operating the stop switches 37L, 37C, 37R. The reels 40L, 40C, and 40R are stopped so that they are not stopped and displayed. The reel stop control means 422 performs such reel stop control, so that when a winning combination is won in the winning lottery, the winning combination is established within a predetermined range, and if it is not possible Each reel is stopped so that no combination other than the winning combination is established. Further, when the result of the combination lottery is lost, each reel is stopped so that no combination is established.

  In addition, as described above, when a bonus combination is carried out while the bonus flag is carried over, if a small role or re-playing role is won, the winning flag of the winning role and the special role (SRB role) being carried over Both of the winning flags (except for) are turned on, and one of these combinations can be established. In this case, the reel stop control means 422 performs reel stop control for preferentially stopping the winning symbol of the selected small role or replaying character at the position of the effective line rather than the winning symbol of the special role. For this reason, there is a possibility that the player may be able to establish a special role while carrying over the bonus flag when the player loses in the role lottery, or when a role that is likely to be missed is elected When the stop switch is operated at a timing at which the combination cannot be established (in other words, the rotational position of the reel).

  In addition, when a small role or re-playing role is won in the role lottery while the bonus flag is being carried over, a reel stop control that preferentially establishes the special role being carried over is performed contrary to the reel stop control described above. You may decide to do it. In this case, the reel stop control means 422 only selects the winning symbol of the selected small role or re-playing role for the effective line only when it is operated at a timing at which the winning symbol of the special role cannot be stopped at the position of the effective line. Reel stop control is performed to stop at the position.

  Further, the reel stop control means 422 is determined in advance in accordance with the operation order of the stop switches 37L, 37C, 37R when a plurality of small combinations 2 are won in the combination lottery or a plurality of replaying combinations are won. The reel stop control is performed so that only one combination is established. Here, FIG. 10 shows the correspondence between the types of the small combinations 2 for which the reel stop control is performed to win a prize and the operation order of the stop switches 37L, 37C, 37R when a plurality of small combinations 2 are simultaneously won in the combination lottery. Show. Also, FIG. 11 shows the correspondence between the types of re-game players whose reel stop control is performed to be established when a plurality of re-game players are won simultaneously, and the operation order of the stop switches 37L, 37C, 37R.

  In FIG. 10, the numbers in the “lottery result number” column indicate the lottery result numbers during the general game (see FIGS. 7 and 8A), and the numbers in parentheses indicate the lottery result numbers during the general game during BB. (See FIG. 9B). Further, in this figure, the “first stop operation” refers to a stop switch operation that is performed first after the reels 40L, 40C, and 40R start to rotate in one game. As shown in FIG. 10, when the lottery result number “7” is derived by the lottery during the general game, if the first stop operation is the left stop switch 37L (that is, the operation order is left → middle → In the case of right or left → right → middle), the reel stop control means 422 controls the reel stop so that the symbol combination (bell-bell-bell) corresponding to the small role 2a is stopped and displayed along the active line. I do. On the other hand, when the first stop operation is the middle stop switch 37C or the right stop switch 37R, the symbol combination (black cherry-character-blue 7) corresponding to the small role 2b is stopped and displayed along the active line. The reel stop control is performed as described above.

  That is, when the lottery result number “7” is derived in the role lottery during the general game, if the player first operates the left stop switch 37L, the small role 2a can be reliably won, but the middle stop When the switch 37C or the right stop switch 37R is operated, there is a possibility that the small part 2b may be missed unless each stop switch is operated at an appropriate timing.

  Similarly, when the lottery result number “8” is derived in the role lottery during the general game, if the first stop operation is the middle stop switch 37C (that is, the operation order is middle → left → right or middle as a result) → Right → Left), the reel stop control means 422 performs reel stop control so that the symbol combination corresponding to the small combination 2a is stopped and displayed along the effective line. On the other hand, when the first stop operation is the left stop switch 37L or the right stop switch 37R, the symbol combination (blue 7-blue cherry-red 7) corresponding to the small role 2c is stopped and displayed along the active line. The reel stop control is performed as described. Therefore, when the first stop operation is the left stop switch 37L or the right stop switch 37R, there is a possibility of missing the small combination 2c.

Further, when the lottery result number “9” is derived by the lottery during the general game, if the first stop operation is the right stop switch 37R (that is, the operation order is right → left → middle or right → middle as a result) (If left), the reel stop control means 422 performs reel stop control so that the symbol combination corresponding to the small combination 2a is stopped and displayed along the active line. On the other hand, if the first stop operation is the left stop switch 37L, the reel stop control is performed so that the symbol combination corresponding to the small role 2b is stopped and displayed along the active line, and the middle stop switch 37C is used. In such a case, the reel stop control is performed so that the symbol combination corresponding to the small combination 2c is stopped and displayed along the active line. Therefore, when the first stop operation is the left stop switch 37L or the middle stop switch 37R, there is a possibility of missing the small combination 2b or the small combination 2c.
The same applies to the case where the lottery result numbers “3” to “5” are derived in the general game during BB.

Next, referring to FIG. 11, when the RT state is “non-RT” or “RT2” in the general game, the operation sequence of the stop switch when a plurality of re-game players are won at the same time in the lottery. The correspondence with the type of re-game player to be established will be described.
In the following, operating each stop switch in the order of left stop switch 37L → middle stop switch 37C → right stop switch 37R is the operation sequence 1, and each stop switch in the order of left stop switch 37L → right stop switch 37R → middle stop switch 37C. Operating sequence 2, operating each stop switch in the order of middle stop switch 37C → left stop switch 37L → right stop switch 37R, operating sequence 3, middle stop switch 37C → right stop switch 37R → left stop switch Each stop switch is operated in order of 37L, operation order 4, right stop switch 37R → left stop switch 37L → middle stop switch 37C, each stop switch is operated in order of operation 5, right stop switch 37R → middle-stop switch 37C → that the operation sequence 6 to operate the stop switch in the order of the left stop switch 37L.

  First, as shown in FIG. 11A, the reel stop control means 422, when any of the lottery result numbers “11” to “16” is derived in the winning lottery, each stop switch is operated in a predetermined operation order. When operated, the reel stop control is performed so that the re-game player a (symbol combination: plum-plum-plum) is established, and when operated in an operation sequence other than the predetermined operation sequence, the re-game game c Reel stop control is performed so that (design combination: plum-plum-bell) is established. In this case, the “predetermined operation order” includes the operation order 1 when the lottery result number “11” is derived, the operation order 2 when the lottery result number “12” is derived, and the lottery result number “13”. If derived, operation order 3; if lottery result number “14” is derived, operation order 4; if lottery result number “15” is derived, operation order 5 and lottery result number “16” are derived. In this case, the operation order is 6.

Also, as shown in FIG. 11B, when any of the lottery result numbers “17” to “22” is derived in the role lottery, the reel stop control unit 422 indicates that each stop switch has a predetermined operation order. The reel stop control is performed so that the re-game player b (symbol combination: plum-plum-watermelon) is established. If the game player is operated in an operation order other than the predetermined operation order, Reel stop control is performed so that c is established. In this case, the “predetermined operation order” includes the operation order 1 when the lottery result number “17” is derived, the operation order 2 when the lottery result number “18” is derived, and the lottery result number “19”. If derived, operation order 3; if lottery result number “20” is derived, operation order 4; if lottery result number “21” is derived, operation order 5; lottery result number “22” is derived. In this case, the operation order is 6.
Note that, as described above, the re-game players a, b, and c are associated with symbol combinations that do not miss out.

<Description of winning determination means>
The winning determination means 430 has a gaming state control means 432, and when all of the reels 40L, 40C, 40R are stopped, it makes a winning determination for determining whether or not any combination is achieved, and the gaming state control means 432 The game state transition control described above is performed according to the result of the winning determination. The winning determination means 430 stores a type code corresponding to the symbol number of each reel shown in FIG. 2, and the nine symbol types displayed on the display window 22 when the reels 40L, 40C, 40R are stopped. Is identified. Then, based on the specified nine symbols, each symbol combination stopped and displayed along each of the effective lines L1 to L5 is recognized, and whether or not any combination is established based on the payout information shown in FIG. Determine whether. In addition, after the determination, the winning flag corresponding to the small combination or replaying combination that is turned on is turned off, and when the special combination is established, the winning flag corresponding to the special combination is turned off.

  The game state control means 432 controls the transition of the game state (“general game”, “RB game”, “BB game”, “SRB game”) according to the establishment of the special role and the completion condition of the special game. To do. In addition, during the general game, the transition of the RT state (“non-RT”, “RT1”, “RT2”, “RT3”) is controlled in accordance with the type of re-game player and the number of games played. Here, with reference to the state transition diagram shown in FIG. 12, the transition of each gaming state and the RT state will be described. First, the game state at the beginning of the game is “general game”, and the RT state is “non-RT”. In this state, when the re-game combination c is established, the game state control means 432 shifts the RT state to “RT3”, and when the re-game combination a is established, shifts to “RT2”. The game state control means 432 shifts the RT state to “RT3” when the re-game combination c is established when the RT state is “RT2”. Further, when the game is played 64 times when the RT state is “RT3”, the game state control means 432 shifts the RT state to “non-RT”. In addition, when the RT state is “RT1”, the transition to “RT2” is made when the re-game combination a is established, and the transition is made to “RT3” when the re-game combination c is established.

  In addition, during the general game, when the BB combination or the RB combination is established, the game state is changed from “general game” to “BB game” according to the established combination regardless of the RT state. "Or" RB game "(special game). When the BB game or RB game end condition is satisfied, the game state is set to “general game” and the RT state is shifted to “RT1”. Further, when the SRB combination is established in the general game during BB, the game state is changed from “BB game” to “SRB game”, and when the SRB game end condition is satisfied, the game state is changed from “SRB game” to “BB”. Move to "Game". Further, when the BB game end condition is satisfied during the SRB game, the game state is shifted to “general game”.

<Explanation of winning process means>
The winning processing means 440 drives a hopper (not shown) provided inside the slot machine 10 when the winning determination means 430 determines that any of the small combinations has been established. Control for paying out the corresponding number of medals (see FIG. 6) is performed.

≪Description of sub control circuit≫
The sub-control circuit 200 mainly includes an effect control unit 510, a specific game period control unit 520, a specific game execution unit 530, an extension period determination unit 540, and a notification control unit 550.

<Description of production control means>
The effect control means 510 includes an effect data storage means 512 and an effect lottery means 514, and controls the effects executed in the notification output means 600. The effect data storage means 512 stores image (moving image or still image) data, sound effects or musical sound data, and blink pattern data of the upper effect lamp 72 for executing various effects. The effect lottery means 514 determines the content of the effect to be executed by lottery according to the result of the role lottery transmitted from the main control circuit 100. Thereby, the effect control means 510 performs various kinds of data (video or still image) data, sound effect or musical sound data corresponding to the effect contents determined by the effect lottery means 514, data indicating the blink pattern of the upper effect lamp 72, and the like. Data is read from the effect data storage means 510, and the display device 70, the speakers 64L and 64R, and the upper effect lamp 72 of the notification output means 600 are driven based on the read various data.

<Description of specific game period control means>
The specific game period control means 520 determines by lottery whether or not to shift to an ART game state (ART game period), and if it is determined to shift to an ART game period, the ART game period (specific Corresponding to the game period). Further, the number of games executed during the ART game period is counted, and when a predetermined number of games (specifically, 30 times) is performed after the ART game period starts, the ART game period is reduced. Terminate.

  In the lottery for determining whether or not to shift to the ART game period (hereinafter referred to as ART transfer lottery), during the general game (except during the ART game or the chance production described later), the small role 1 wins a prize. When done. The result of the ART lottery is stored as transfer information in the RAM 210 shown in FIG. The transition information is information represented by “0” or “1”. When it is determined that the transition to the ART game period is made as a result of the lottery, the transition information becomes “1” and the transition to the ART game period is not performed. It is “0” when it is determined. Here, the probability that it is determined to shift to the ART game period is set to 1/250.

  Further, the transition information indicating the result of the ART lottery is stored and accumulated in the RAM 210 in association with the order in which the ART lottery is performed. When a predetermined condition is established, the player is informed of whether or not to shift to the ART gaming period based on the transition information stored in the RAM 210. And when notifying that it shifts to an ART game period, an ART game period is started from the next game. In other words, during the general game, based on the ART game period, the lottery result accumulation period in which the ART shift lottery is performed every time the small role 1 wins, and the transfer information accumulated during the lottery result accumulation period. Thus, there is a transition notification period for notifying whether or not to shift to the ART game period.

  Then, during the lottery result accumulation period, when the RT state is “RT3” and the number of pieces of transfer information stored in the RAM 210 matches the number of remaining games of “RT3”, the transition to the transition notification period is made. To do. Here, when the ART lottery is performed during the lottery result accumulation period, as shown in FIG. 13, the transition information as a result is accumulated in association with the order in which the ART lottery was performed. The example shown in FIG. 13 shows a state in which four pieces of migration information are accumulated, and the ART lottery performed first after the lottery result accumulation period starts (in FIG. 13, “determination order” column “ 1 ”), the transition information is“ 0 ”, the second ART lottery performed (“ 2 ”in the“ decision order ”column in the figure) is the transition information“ 0 ”, the third The migration information that is the result of the ART lottery performed in the figure (“3” in the “decision order” column in the figure) is “1”, and the ART lottery performed in the fourth (the “decision order” column in the figure) "4") indicates that the migration information is "0".

  Then, when 60 games are played after the RT state becomes “RT3” (that is, the remaining number of games of “RT3” is “4”), four pieces of transition information are accumulated as shown in FIG. If it is, the transition notification period starts from the next game. When the transition notification period is started, every time a game is performed, among the transition information accumulated in the RAM 210, the earliest transition information (transition information whose “decision order” is “1”) is sequentially Notification is made as to whether or not to shift to the ART game period depending on whether the value of the transfer information is “0” or “1”. That is, in the case shown in FIG. 13, in the first game and the second game after the transition notification period, it is informed that the transition to the ART game period is not made, and the ART game period is entered when the third game is performed. It is informed that it will shift. When it is notified that the ART game period is to be entered, the ART game period is started from the next game. When the ART game period is started and 30 games are played, the ART game period ends and the lottery result accumulation period starts again. At this time, the transition information whose “determination order” is “4” shown in FIG. 13 is the first transition information. That is, of the migration information stored in the RAM 210, the migration information after the earliest migration information whose value is “1” (in the case of FIG. 13, the migration information whose “decision order” is “3”) It will be carried over to the next lottery result accumulation period.

  If all the values of the transition information stored in the RAM 210 are “0”, the lottery result storage period is started again without starting the ART game period when the transition notification period ends. In addition, when a special combination is established during the lottery result accumulation period, the transition notification period, and the ART game period, the special game is started from the next game, and when the special game ends, the lottery result accumulation period is started again. . At this time, the transition information stored in the RAM 210 until immediately before the special game is started is held even during the special game.

  Further, the specific game period control means 520 executes the corresponding effects on the display device 70 in the lottery result accumulation period, the transition notification period, and the ART game period described above. First, during the lottery result accumulation period, the roadwork effect shown in FIG. 14 is performed. In the roadwork effect, a moving image in which the character C is performing roadwork is displayed on the screen, and each time an ART lottery is performed, an image of a glove is additionally displayed. In the example shown in FIG. 14, four globe images G1 to G4 are displayed, indicating that four ART lotteries have been performed. Further, in the example illustrated in FIG. 14, the globe image G1 corresponds to the earliest transition information, and the more right-side globe information corresponds to the transition information determined most recently. During the roadwork production, the production lottery means 514 displays a video showing the event corresponding to the winning combination determined in the role lottery (hereinafter referred to as an event) on the display device 70, and thereby the result of the role lottery is displayed to the player. To inform.

  Next, during the transition notification period, the chance effect shown in FIG. 15 is performed. In the chance production, every time a game is played, the glove image displayed during the roadwork production is consumed, and the three image reels LR, CR, RR displayed on the screen are changed and stopped. Whether or not to shift to the ART state is notified by the symbol combination when all the image reels are stopped and displayed. Specifically, each of the three image reels can display either an “ART” symbol or a “losing” symbol, and when the start switch 36 is operated, these symbols are variably displayed. Then, every time the stop switches 37L, 37C, and 37R are operated, the change display of the image reel corresponding to the operated stop switch is stopped.

  Here, the image reel LR corresponds to the left stop switch 37L, the image reel CR corresponds to the middle stop switch 37C, and the image reel RR corresponds to the right stop switch 37R. When the value of the transition information for the consumed globe image is “1”, the “ART” symbol is stopped and displayed on all the image reels. On the other hand, when the value of the transition information is “0”, the “lost” symbol is stopped and displayed on any or all of the image reels.

  Further, during the ART game period, the ART game effect shown in FIG. 16 is performed. In the ART game effect, notification regarding the operation order of stop switches 37L, 37C, and 37R described later and notification of the number of games performed during the ART game period are performed. As shown in FIG. 16A, the number of games is notified by numbers in a game number display area CNT provided in the ART game effect screen. Specifically, the number “30” is displayed immediately after the ART game period is started, and thereafter, “29”, “28”,... Are subtracted each time a game is played. To go.

<Description of specific game execution means>
When any of the lottery result numbers “7” to “9” is derived by the combination lottery unit 410 during the specific game period, the specific game execution unit 530 performs the first stop operation to win the small combination 2a. A stop switch (see FIG. 10) to be notified is notified. For example, when the lottery result number “7” is derived, the left operation instruction lamp 24L is lit, and when the lottery result number “8” is derived, the middle operation instruction lamp 24C is lit, and the lottery result number “ When “9” is derived, the right operation instruction lamp 24R is turned on.

  In addition, when any of the lottery result numbers “11” to “16” is derived by the combination lottery means 410 during the specific game period, the operation sequence in which the re-game combination a is established (FIG. 11 (a ))), And when any of the lottery result numbers “17” to “22” is derived, the operation order (see FIG. 11B) in which the re-game player b is established is notified. . As an operation order notification method, for example, when the lottery result number is derived and the operation order is fixed, the operation instruction lamp 24 corresponding to the stop switch 37 to be operated for the first stop is turned on, and the first stop operation is performed. When the second stop operation is performed, the operation instruction lamp 24 corresponding to the stop switch 37 to be operated for the second stop operation is turned on. Each time a stop operation is performed on the stop switch, the operation instruction lamps corresponding to the stop switch to be operated next are sequentially turned on.

Further, the specific game executing means 530 uses the images displayed on the display device 70 in the ART game effect shown in FIG. 16 in addition to the notification of the operation order by the operation instruction lamps 24L, 24C, 24R. , 37R is notified. For example, as shown in FIG. 16A, in the screen of the display device 70, a stop instruction image area STL corresponding to the left stop switch 37L, a stop instruction image area STC corresponding to the middle stop switch 37C, and a right stop switch 37R. A stop instruction image area STR corresponding to is provided, and a circle number indicating the operation order of each stop is displayed. Further, the size of the circled numbers decreases in order from the first stop operation. Therefore, in the example shown in FIG. 16A, the operation order 3 (middle → left → right) is designated, and in the example shown in FIG. 16B, the operation order 1 (left → middle → right) is designated.
In addition to the above-described method, the notification method of the operation order by the image can employ the conventional method of notifying the stop switch by the image.

<Explanation of extension period determining means>
The extension period determining unit 540 determines whether or not to extend the specific game period on condition that the specific combination is determined as the winning combination by the combination lottery unit 410 during the specific game period. Specifically, in the role lottery by the role lottery means 410, the lottery result number “6” is derived (that is, when only the small role 1 is determined as the winning role), and the small role 1 cannot be won. When the event is missed, an extended lottery will be conducted to determine the extension period. The contents of the lottery table used in this extended lottery are shown in FIG. The extension period determined by the extension period determination means 540 is defined by the number of games. In the extended lottery, one random number is generated within a numerical value range of 0 to 255, and in the lottery table shown in FIG. 17, the number of games (addition game number EG) corresponding to the numerical section to which the generated random number value belongs is an extended period. It becomes. Hereinafter, a game played during this extended period is also referred to as an added game.

  In the lottery table shown in FIG. 17, numbers are shown instead of numerical intervals corresponding to the number of extra games EG. Further, if the corresponding extra game number EG is “0”, the extension period is not determined. Furthermore, there are two types of extended lottery tables: “chance eye stop display” and “chance eye non-stop display”. Here, the chance chance refers to a specific symbol combination that is stopped and displayed when the small role 1 is missed. Specifically, “red 7-blue cherry-watermelon” and “blue 7-blue cherry-watermelon” The symbol combination “” is stopped and displayed along one of the effective lines. In these chances, the stop switches 37L, 37C, and 37R are operated at a timing at which the symbol combination (character-blue cherry-red cherry) corresponding to the small role 1 cannot be stopped and displayed along the active line, and In this case, when the symbol constituting the above-described chance eye is in a position where it can be stopped on the effective line by the reel stop control described above, the stop display is performed. The chance is a symbol combination that can be displayed only when the small role 1 is missed, and is not displayed when the game is lost in the role lottery or when another role is missed.

  If the chance eye is stopped and displayed when the small role 1 is missed, the extra game number EG is determined based on the lottery table shown in the “chance eye stop display” field, and the symbol combinations other than the chance eye are determined. When the stop display is made, the extra game number EG is determined based on the lottery table shown in the “chance eye non-stop display” column. Here, when looking at each lottery table, when the chance eyes are not displayed in a stopped state, the probability that the added game number EG is determined to be 10 times or more is about 1/10, whereas the chance eyes are displayed in a stopped state. In this case, a high probability of 1/2 is set. In addition, when the chance is stopped and displayed, the number of extra games EG is 10000 with a probability of 1/256, but when the chance is not stopped and displayed, there is no possibility.

<Description of notification control means>
The notification control means 550 controls notification related to the ART game period and the extension period. That is, first, the number of games played during the ART game period is subtracted and displayed in the game number display area CNT shown in FIG. Also, in a game during the ART game period, when the extension period (additional game count EG) is determined by the extension period determination means 540, the number of games is displayed until the extension period determined from the next game ends. Instead of the numbers displayed in the area CNT, as shown in FIG. 16 (b), the characters “added” (corresponding to the extension determination information) are displayed, and the number of games played during the extension period is not displayed. Like that.

  Further, the notification control means 550 extends when the number of games played during the extension period coincides with any of the additional number of games EG (10, 30, 60, 90, 10000) that can be determined by the extension period determination means 540. The effect of continuing whether or not the period is continued is performed. For example, when the number of extra games EG is determined to be “90” by the extension period determining means 540, when the tenth, thirty, sixty, and ninetyth games are played after the extension period starts, continuous notification is made. Production is performed. In this case, in the continuation effect that is executed when the 10th, 30th, and 60th games are performed, at the end of the effect, the player is informed that the game will be continued, and is executed when the 90th game is performed. In the continuation effect, the player is notified at the end of the effect that the extension period has ended. Note that the effect content of the continuation effect is the same until it is finally notified whether the extension period continues or ends.

  In this way, each time a game is played a number of times during the extension period, the player can feel nervous about the continuity of the extension period by directing whether the extension period continues or ends. By giving, there is a possibility that the interest of the game is improved.

  Furthermore, when the chance item is stopped and displayed, the notification control unit 550 performs a privilege effect indicating whether the BB combination is won by the combination lottery or whether the extension period is determined by the extension period determination unit 540. In other words, the chance item can be stopped and displayed when the small role 1 is missed. Therefore, when one of the lottery result numbers “4” to “6” is derived by the combination lottery means 410, the chance item is displayed. Can be stopped (see FIGS. 7 and 8). When the chance chance is stopped and displayed, the notification control means 550 performs a bonus effect, and when the lottery result number “4” or “5” is derived by the winning lottery means 410, BB is provided at the end of the bonus effect. When the player is informed that the combination a or BB combination b has been won internally, the lottery result number “6” is derived, and the extension period determining means 540 determines the number of times EG to be added more than 10 times The player is notified that the extension period has been determined at the end of the bonus presentation. Note that this bonus effect has the same content until it is finally notified whether the BB combination has been won or whether the extension period has been determined.

[Description of control processing in main control circuit]
≪Description of main routine≫
First, a description will be given of the control processing of the main routine executed by the CPU 106 of the main control circuit 100 with reference to the flowchart of FIG. This main routine shows a control process when a game is performed in which one step from when a player inserts a game medium until the reels 40L, 40C, 40R are rotated and stopped is performed once.

  When the slot machine 10 is turned on, the CPU 106 performs a predetermined self-check and sets various flags and initial values of control data stored in the RAM 110 (step S10). Next, the CPU 106 determines whether or not the re-game establishment flag stored in the RAM 110 is turned on (step S12). This re-game establishment flag is turned on in step S202 of the RT transition processing subroutine shown in FIG. 24 described later when a re-game player is established in the previous game. When determining that the re-game establishment flag is off (NO), the CPU 106 determines whether or not the bet operation signal transmitted by operating the bet switch 34 or 35 has been received (step S14). When determining that the bet operation signal has been received (YES), the CPU 106 determines whether or not the number of medals corresponding to the operated bet switch has been credited (step S16).

  If the value of the number of credits stored in the RAM 110 is less than the value of the number of medals corresponding to the operated bet switch (hereinafter referred to as the number of inserted coins), it is determined that there are no credited medals (NO). The process returns to step S14 again. On the other hand, if the value of the number of credits stored in the RAM 110 is equal to or greater than the value of the inserted number, it is determined in step S16 that there is a credited medal (YES). In this case, the CPU 106 subtracts the inserted number value from the credit number value stored in the RAM 110 (step S18). Then, the CPU 106 adds the value of the inserted number to the value of the bet number stored in the RAM 110, and according to the value of the bet number after the addition, the bet number display lamps 26a, 26b, 26c shown in FIG. The lighting state of is updated (step S20). Next, the CPU 106 determines whether or not the value of the bet number stored in the RAM 110 has reached the specified number (three) (step S22), and determines that the specified number has not been reached (NO) Returning to step S14, if it is determined that it has reached (YES), it is determined whether or not the start switch 36 has been operated by the player (step S24).

  On the other hand, if it is determined in step S14 that a bet operation signal has not been received (NO), the CPU 106 determines whether or not a medal has been inserted from the medal insertion slot 32 (step S26). That is, when a medal is detected by the medal sensor installed in the medal insertion slot 32, it is determined that a medal has been inserted (YES), the process proceeds to step S20, and the number of bets stored in the RAM 110 is determined. Add “1” to the value. In step S22, it is determined whether or not the number of inserted medals has reached a specified number. In contrast, if no medal is detected by the medal sensor in step S24, it is determined that no medal has been inserted (NO), and the process returns to step S14.

  If it is determined in step S12 described above that the re-game establishment flag is on (YES), the CPU 106 turns off the re-game establishment flag (step S28), and then proceeds to step S24 to play the game. It is determined whether the start switch 36 has been operated by a person. As a result, in the next game in which the re-game role is established, a new medal can be inserted or the game can be played again without consuming the credited medal. Further, the bet number in the previous game stored in the RAM 110 is used as the bet number in the re-game.

  In step S <b> 24, the CPU 106 determines whether a reel rotation start signal has been received from the start switch 36. If the reel rotation start signal has not been received and it is determined that the start switch 36 has not been operated by the player (NO), the determination in step S24 is performed again. Until the reel rotation start signal is received, the CPU 106 repeats the process of step S24. If a medal is inserted from the medal slot 32 during this period, the number of inserted medals may be added to the value of the number of credits stored in the RAM 110. If the CPU 106 receives the reel rotation start signal in step S24 and determines that the start switch 36 has been operated by the player (YES), the combination lottery processing subroutine shown in FIG. 19 is executed (step S30). As a result of executing the subroutine, when a winning combination is won, the winning flag of the winning combination is turned on among the winning flags corresponding to each combination stored in the RAM 110.

  Next, the CPU 106 executes a reel fluctuation / stop subroutine for controlling the movement of the reels to be stopped after rotating the reels 40L, 40C, 40R based on the result of lottery drawing obtained by the process of step S30. (Step S32). Details of the reel fluctuation / stop subroutine will be described later with reference to the flowchart of FIG. When all the reels 40L, 40C, and 40R are stopped by executing the reel fluctuation / stop subroutine in step S32, the CPU 106 next determines whether or not any combination has been established, and the gaming state is determined according to the determination result. And the winning determination process subroutine which performs the transition process of RT state is performed (step S34). The details of this subroutine will be described later with reference to the flowcharts of FIGS.

  Then, after executing the winning determination processing subroutine in step S34, the CPU 106 performs a payout process (step S36) for paying out the number of medals corresponding to the small combination when winning a small combination. This payout process corresponds to the process performed by the winning processing means 440 shown in FIG. 5, and it is possible to actually pay out medals from the medal payout outlet 60, and the number of medals to be paid out is stored in the RAM 110. It is also possible to add credit to the stored number of credits. One game is completed by the above control process, and the CPU 106 returns to the process of step S12 again. Thus, by repeating the control process shown in the main routine, the player can continue to play the game.

<Description of role lottery processing subroutine>
Next, the combination lottery processing subroutine performed in step S30 of the main routine will be described in detail with reference to the flowchart shown in FIG.

  First, the CPU 106 refers to the current gaming state stored in the RAM 110, and determines whether or not the current gaming state is a BB game (step S40). If it is determined that the current gaming state is BB gaming (YES), the winning lottery table shown in FIG. 9B is selected from the winning lottery tables stored in the ROM 108 (step S42). On the other hand, when determining that the current gaming state is not BB gaming (NO), the CPU 106 determines whether or not the current gaming state is RB gaming or SRB gaming (step S44). When it is determined that the current gaming state is RB gaming or SRB gaming (YES), the winning lottery table shown in FIG. 9A is selected from the winning lottery tables stored in the ROM 108 (step) S46). In step S44, if the CPU 106 determines that the current gaming state is not an RB game or an SRB game (NO), the current gaming state is regarded as a general game, and the current RT state stored in the RAM 110 is determined. A combination lottery table (see FIGS. 7 and 8) corresponding to (“non-RT”, “RT1”, “RT2” or “RT3”) is selected from the ROM 108 (step S48).

  When the combination lottery table is selected by the processing of steps S40 to S48 described above, the CPU 106 acquires a random number generated by the random number generator 112 and has won any combination in comparison with the selected combination lottery table, or Then, it is determined whether or not it has been lost (step S50). That is, the acquired random number is sequentially compared with each numerical range of the selected combination lottery table, and a lottery result number corresponding to the numerical range including the acquired random number is derived as a result of the combination lottery. The processing in step S50 corresponds to the random number extraction unit 412 and the random number determination unit 414 shown in FIG.

  Next, the CPU 106 turns on the winning flag of the combination corresponding to the lottery result number derived by the combination lottery. Note that the ON / OFF state of the winning flag corresponding to each combination is stored in a predetermined storage area of the RAM 110. First, the CPU 106 determines whether or not any of the small roles 1, small roles 2a to 2c, and small roles 3 has been won from the derived lottery result number (step S52). If it is determined that any small combination has been won (YES), the CPU 106 turns on the state of the winning flag corresponding to the selected small combination stored in the RAM 110 (step S54). Furthermore, when a plurality of small roles 2 are won simultaneously in a single role lottery, the relationship between the operation sequence of the stop switch and the type of the small role 2 to be won according to the types of the plurality of small roles 2 simultaneously won Is recognized (step S56). That is, it recognizes the type (left, middle or right) of the stop switch of the first stop operation corresponding to the lottery result number derived by the lottery lottery that the small role 2a will win (see FIG. 10). When the general game is being played, when the lottery result numbers “7” to “9” are derived, and during the BB general game, when the lottery result numbers “3” to “5” are derived, The process of step S56 is performed.

  If it is determined in step S52 that no small combination has been won (NO), it is next determined whether any re-game combination has been won (step S58). If it is determined that any of the re-playing combinations has been won (YES), the CPU 106 turns on a re-playing winning flag corresponding to the selected re-playing combination (step S60). Furthermore, when a plurality of re-game players are won at the same time, the relationship between the operation order of the stop switches and the types of re-game players to be established according to the types of the plurality of re-game players won simultaneously (see FIG. 11). Is recognized (step S62).

  In step S58, when it is determined that no re-playing combination has been won (NO), the winning flag corresponding to the BB combination a, BB combination b and RB combination stored in the RAM 110 is turned on next. It is determined whether or not the bonus flag is being carried over (step S64). When determining that the bonus flag has not been carried over (NO), the CPU 106 determines whether or not the BB combination a or the BB combination b has been won (step S66). If it is determined that the BB combination a or the BB combination b has been won (YES), the state of the winning flag corresponding to the selected BB combination is turned on (step S68). On the other hand, when it is determined that no BB combination has been won (step S66, NO), the CPU 106 determines whether or not the RB combination or SRB combination has been won (step S70). If it is determined that the RB combination or SRB combination is won (YES), the state of the winning flag corresponding to the winning combination is turned on (step S72).

  If the winning flag corresponding to the winning combination is turned on as a result of the lottery by the above processing, the CPU 106 stores the lottery result number derived in the winning lottery in the RAM 110 (step S74). If it is determined in step S64 described above that the bonus flag is being carried over (YES), the process of step S74 is performed as it is. Thus, even if the BB combination a, BB combination b or RB combination is won in the combination lottery while the bonus flag is carried over, the winning flag is not turned on. If it is determined in step S70 described above that the RB combination or SRB combination is not won (NO), it is considered that the result of the lottery is lost, and the process proceeds to step S74.

  Next, the CPU 106 transmits role lottery information including the derived lottery result number to the sub-control circuit 200 (step S76), ends the role lottery processing subroutine, and performs step S32 of the main routine shown in FIG. Proceed to processing.

<Explanation of reel fluctuation / stop subroutine>
In the main routine shown in FIG. 18, when the above-described combination lottery processing subroutine (step S30) is completed, the CPU 106 next performs a reel variation / stop subroutine (step S32). Hereinafter, the reel fluctuation / stop subroutine will be described in detail with reference to the flowchart shown in FIG.

  First, the CPU 106 recognizes the on / off state of the winning flag for each combination stored in the RAM 110 (step S80). Then, it is determined whether or not a predetermined shortest time (for example, 4.1 seconds) has elapsed since the reels 40L, 40C, and 40R started rotating in the previous game (step S82). If it is determined that the shortest time has not elapsed (NO), the determination process in step S82 is repeatedly executed. In other words, until the minimum time elapses, the rotation of the reel, which is the next step, is not performed, so that the number of medals consumed in a game performed within a certain time does not exceed a predetermined number. Control is in progress. If it is determined that the shortest time has elapsed (YES), the CPU 106 sequentially outputs drive pulses to the motor drive circuit 114, drives the stepping motors 80L, 80C, and 80R, and rotates the reels 40L, 40C, 40R all at once. (Step S84).

  Next, the CPU 106 determines whether or not all the reels 40L, 40C, and 40R have reached the steady rotation speed (step S86). When it is determined that the reel rotation speed has not reached the steady rotation speed (NO), the determination process of step S86 is repeated. Thus, until the reel rotation speed reaches the steady rotation speed, even if the player operates the stop switches 37L, 37C, and 37R, the reel stop control is not performed. If the CPU 106 determines that the rotation speeds of all the reels have reached the steady rotation speed (YES), it determines whether or not a reel stop signal has been received from the stop switches 37L, 37C, and 37R (step). S88). This reel stop signal is transmitted from each of the stop switches 37L, 37C, and 37R when the player performs a push operation. If it is determined that the reel stop signal has been received (YES), the CPU 106 transmits stop operation information indicating the stop switch that has transmitted the reel stop signal among the stop switches 37L, 37C, and 37R to the sub-control circuit 200 ( Step S90).

  Next, the CPU 106 performs symbol combination control based on the ON / OFF state of the winning flag of each winning recognized in step S80 so that the winning combination corresponding to the winning flag in the ON state is established (step ST S92). This symbol combination control is the same as the reel stop control performed by the reel stop control means 422 shown in FIG. When a plurality of small combinations 2 or replaying combinations are won, the symbol combination control is performed so that the combination recognized in step S56 or S62 in FIG.

  When the reel corresponding to the stop switch that has transmitted the reel stop signal is stopped by the process of step S92, the CPU 106 determines whether or not all the reels have been stopped (step S94). If it is determined that all the reels are not stopped (NO), the process returns to step S88, and the symbol combination control according to the result of the winning lottery is performed again according to the reel stop signal. If it is determined in step S88 that a reel stop signal has not been received (NO), the process proceeds directly to step S94 to determine whether all reels have been stopped. As described above, the processes in steps S88 to S94 are repeated until all the reels are stopped. When the CPU 106 determines that all the reels are stopped (YES) in step S94, the CPU 106 stops all the reels. An all-reel stop signal indicating this is transmitted to the sub-control circuit 200 (step S96). Then, the reel changing / stopping process is terminated, and the process proceeds to step S34 of the main routine shown in FIG.

<Description of the winning determination processing subroutine>
In the main routine of FIG. 18, when the reel fluctuation / stop subroutine (step S32) is completed, the CPU 106 then executes a winning determination process subroutine (step S34). Hereinafter, a detailed description will be given using the flowchart of the winning determination processing subroutine shown in FIG.

  First, the CPU 106 recognizes nine types of symbols stopped and displayed on the display window 22 (step S100). Then, the CPU 106 refers to information indicating the current gaming state stored in the RAM 110, and determines whether or not the current gaming state is “RB gaming” (step S102). When determining that the RB game is being played (YES), the CPU 106 subtracts “1” from the value of GCNT stored in the RAM 110 (step S104). This GCNT is a variable for counting the number of games played during the RB game, and the initial value “12” is set in step S176 of FIG. 23 described later.

  Next, the CPU 106 determines whether or not any of the small combination 1, the small combination 2a and the small combination 3 has won a prize based on the nine symbols recognized in step S100 (step S106). If the CPU 106 determines that any small role has won (YES), the payout number of medals corresponding to the winning small role is read from the payout information shown in FIG. Is updated to the value of the read payout number (step S108). Here, the value of the payout number count indicates the number of medals to be paid out to the player by the payout process in step S36 of FIG. Next, the CPU 106 subtracts “1” from the value of WCNT stored in the RAM 110 (step S110). This WCNT is a variable for counting the number of times a small combination has won during the RB game, and the initial value “8” is set in step S176 of FIG. 23 described later. On the other hand, when it is determined in step S106 that none of the small roles has been won (NO), the above-mentioned payout number count value is cleared (that is, the value is set to “0”) (step S112).

  When the processing of step S110 or S112 is performed, the CPU 106 determines whether or not the RB game end condition is satisfied. That is, it is determined whether or not the value of either GCNT or WCNT has become “0” (step S114). If the value of either GCNT or WCNT is “0” (YES), it is considered that the RB game end condition is satisfied, and the current game state stored in the RAM 110 is “RB game”. Is updated to “general game” (step S116). Further, the CPU 106 updates the current RT state stored in the RAM 110 to “RT1” (step S118). Next, the CPU 106 turns off only the winning flags of all the small combinations and replaying combinations stored in the RAM 110 (step S120). That is, the winning flag for the BB combination a, the BB combination b, the RB combination and the SRB combination is not turned off by the processing of step S120.

  Next, the CPU 106 transmits the game result information of the current game, the current game state information, and the number of games in RT3 (described later) to the sub-control circuit 200 (step S122). Here, the game result information includes information indicating the symbol number stopped and displayed on the display window 22 in each reel recognized in step S100. The game state information includes information indicating the current game state and the RT state. Then, when the game result information and the game state information are transmitted to the sub control circuit 200 by the process of step S122, the CPU 106 ends the winning determination process shown in FIG. 21, and proceeds to the process of step S34 shown in FIG. move on.

  In step S102 described above, when the CPU 106 determines that the current gaming state is not “RB gaming” (NO), next, whether or not the current gaming state is “BB gaming” or “SRB gaming”. Is determined (step S124). When it is determined that the current gaming state is “BB gaming” or “SRB gaming” (YES), the CPU 106 performs a BB gaming process which will be described in detail below (step S126). On the other hand, if it is determined in step S124 that the current game state is neither “BB game” nor “SRB game” (NO), the CPU 106 determines that the current game state is “general game”. Therefore, a general game process which will be described in detail later is performed (step S128). Then, when the process of step S126 or S128 is completed, the process proceeds to the above-described step S120, and only the winning flags of all the small combinations and replaying combinations stored in the RAM 110 are turned off. Thereafter, the CPU 106 proceeds to step S122 to transmit the game result information of the current game, the current game state information, and the number of games in RT3 to the sub-control circuit 200, and finishes the winning determination process shown in FIG. To do.

<Description of processing subroutine during BB game>
Next, the contents of the BB gaming process subroutine executed in step S126 of the winning determination process subroutine shown in FIG. 21 will be described using the flowchart shown in FIG.

  First, the CPU 106 determines whether or not the current gaming state stored in the RAM 110 is “SRB gaming” (step S130). When determining that the SRB game is being played (YES), the CPU 106 subtracts “1” from the value of GCNT stored in the RAM 110 (step S132). This GCNT is a variable for counting the number of games played during the SRB game, and the initial value “12” is set in step S160 described later.

  Next, based on the nine symbols recognized in step S100 in FIG. 21, the CPU 106 determines whether or not any of the small combination 1, the small combination 2a, and the small combination 3 has won (step S134). If the CPU 106 determines that any small combination has won (YES), the payout number of medals corresponding to the winning small combination is read from the payout information shown in FIG. Is updated to the value of the read payout number (step S136). Next, the CPU 106 adds the payout number of medals corresponding to the above-mentioned winning small combination to the value of the BB payout number count stored in the RAM 110 (step S138). Here, the BB payout number count is for counting the total number of medals paid out during the BB game, and when the value of the BB payout number count exceeds 300, the CPU 106 It is determined that the end condition is satisfied.

  Next, the CPU 106 subtracts “1” from the value of WCNT stored in the RAM 110 (step S140). This WCNT is a variable for counting the number of times a small combination has won during the SRB game, and the initial value “8” is set in step S160 described later. On the other hand, if it is determined in step S134 that none of the small roles has been won (NO), the above-mentioned payout number count value is cleared (that is, the value is set to “0”) (step S142). When the process of step S140 or S142 is performed, the CPU 106 determines whether or not the SRB game end condition is satisfied. That is, it is determined whether or not the value of either GCNT or WCNT has become “0” (step S144). If the value of either GCNT or WCNT is “0” (YES), it is considered that the SRB game end condition is satisfied, and the current game state stored in the RAM 110 is “SRB game”. Is updated to “BB game” (step S146).

  Next, the CPU 106 refers to the value of the BB payout count stored in the RAM 110 and determines whether or not the value exceeds 300 (step S148). When the CPU 106 determines that the number exceeds 200 (YES), it is considered that the BB game end condition is satisfied, and the current game state stored in the RAM 110 is updated from “BB game” to “general game”. (Step S150). Then, the CPU 106 updates the current RT state stored in the RAM 110 to “RT1” (step S152), ends the BB gaming process shown in FIG. 22, and proceeds to the process of step S120 in FIG. To do. On the other hand, if the CPU 106 determines in step S148 that the BB payout count value does not exceed 300 (NO), it is considered that the BB game end condition is not satisfied, and the BB shown in FIG. The in-game process is terminated, and the process proceeds to step S120 in FIG.

  When the CPU 106 determines that the current gaming state is not “SRB gaming” (NO) in step S130 described above, is the SRB combination established based on the nine symbols recognized in step S100 in FIG. It is determined whether or not (step S154). When determining that the SRB combination is established (YES), the CPU 106 turns off the winning flag corresponding to the SRB combination stored in the RAM 110 (step S156), and updates the current game state to “SRB game” (step S156). Step S158). Next, the CPU 106 sets the GCNT value stored in the RAM 110 to “12”, sets the WCNT value to “8” (step S160), and clears the payout number count value to “0”. (Step S162). Then, the process proceeds to step S148 described above, and it is determined whether or not the BB game end condition is satisfied. If the BB game end condition is satisfied, the processing of steps S150 and S152 is performed, and then the BB game is performed. The middle processing subroutine is terminated, and the process proceeds to step S120 in FIG.

  In addition, in the process of step S154 described above, when the CPU 106 determines that the SRB combination is not established (NO), any of the small combinations 1, small combinations 2a to 2c, and small combinations 3 won next. Whether or not (step S164). If it is determined that any small combination has been established (YES), the CPU 106 reads out the number of medals to be paid out corresponding to the winning small combination from the payout information shown in FIG. The count value is updated to the value of the read payout number (step S166). Then, the CPU 106 adds the value of the number of payouts updated in step S166 to the value of the payout count in BB stored in the RAM 110 (step S168), and then proceeds to the above-described step S148 to finish the BB game end condition If the BB game end condition is satisfied, the processing in steps S150 and S152 is performed, and then the BB game in-process subroutine is ended, and the process proceeds to step S120 in FIG. .

<Description of general game processing subroutine>
Next, the contents of the general game processing subroutine executed in step S128 of the winning determination processing subroutine shown in FIG. 21 will be described with reference to the flowchart shown in FIG. First, the CPU 106 determines whether or not an RB combination has been established based on the nine symbols recognized in step S100 of FIG. 21 (step S170). If the RB combination has been established (YES), the CPU 106 updates the winning flag corresponding to the RB combination stored in the RAM 110 from on to off (step S172), and changes the current gaming state to “ The game is updated from “general game” to “RB game” (step S174). Next, the CPU 106 sets the value of the variable GCNT stored in the RAM 110 to “12” and the value of the variable WCNT to “8” (step S176). Then, the CPU 106 clears the payout number count value to “0” (step S178), ends the general gaming processing subroutine, and proceeds to step S120 in FIG.

  If the CPU 106 determines in step S170 described above that the RB combination is not established (NO), then the CPU 106 determines whether or not the BB combination a or BB combination b is established (step S180). If it is determined that the BB combination a or the BB combination b is established (YES), the CPU 106 updates the state of the winning flag of the BB combination that is turned off (step S182), and sets the current gaming state to “ After updating from “general game” to “BB game” (step S184), the value of the BB payout count stored in the RAM 110 is cleared to “0” (step S186). Then, the process proceeds to step S178 described above, and after the value of the payout number count is cleared to “0”, the general game processing subroutine is terminated, and the process proceeds to step S120 in FIG.

  If the CPU 106 determines in step S180 described above that neither the BB combination a nor the BB combination b is established (NO), RT transition processing described in detail below is performed (step S188). Then, when the RT transition process is completed, the CPU 106 determines whether or not the current RT state stored in the RAM 110 is “RT3” (step S190). If it is determined that the current RT state is “RT3” (YES), “1” is subtracted from the value of RT3CNT stored in the RAM 110 (step S192). The value of RT3CNT indicates the number of remaining games in the gaming state of RT3, and the initial value (“64”) is determined in the RT transition processing subroutine described below, and the RT state has transitioned to “RT3”. Is set in a predetermined storage area of the RAM 110. In addition, the value of RT3CNT is transmitted to the sub-control circuit 200 together with the game result information and the game state information in step S122 of the above-described winning determination processing subroutine (see FIG. 21).

  Next, the CPU 106 determines whether or not the above-described RT3CNT value has become “0” (step S194). When it is determined that the value has reached “0” (YES), the current RT state is updated from “RT3” to “non-RT” (step S196), and the general game processing subroutine is terminated, and FIG. The process proceeds to step S120. Thus, when 64 games are played after the RT state has shifted to “RT3”, the state shifts to “non-RT” (see FIG. 12). On the other hand, when CPU 106 determines in step S190 described above that the current RT state is not “RT3” (NO), or in step S194, it is determined that the value of RT3CNT is not “0” (NO). If it is, the general game processing subroutine is terminated as it is, and the process proceeds to step S120 in FIG.

<Explanation of RT transfer processing subroutine>
Next, the contents of the RT transition processing subroutine executed in step S188 of the general gaming processing subroutine shown in FIG. 23 will be described using the flowchart shown in FIG. First, the CPU 106 determines whether or not any re-game player has been established based on the nine symbols recognized in step S100 of FIG. 21 (step S200). Then, when any of the re-games is established (YES), the CPU 106 turns on the state of the re-game establishment flag stored in the RAM 110 (step S202). Next, the CPU 106 determines whether or not the current RT state stored in the RAM 110 is “non-RT” (step S204). When the CPU 106 determines that it is “non-RT” (YES), it is determined whether or not the established re-game player is the re-game game c (step S206), and the re-game game c has been established. If (YES), the current RT state is updated to “RT3” (step S208). Then, the CPU 106 sets “64”, which is the number of games in which the “RT3” state continues, to the value of RT3CNT stored in the RAM 110 (step S210). On the other hand, in step S206, it is determined whether or not the re-gamer determined to have been established in step S200 is re-gamer a (step S212). If the CPU 106 determines that the re-gamer a is established (YES), the current RT state is updated to “RT2” (step S214).

  Further, when the CPU 106 determines in step S204 described above that the current RT state is not “non-RT” (NO), it is next determined whether or not the current RT state is “RT1” or “RT2”. Judgment is made (step S216). When the current RT state is either “RT1” or “RT2” (YES), the CPU 106 determines whether or not the established re-game player is the re-game game c (step S218). If it is determined that the re-gamer c has been established (YES), the process proceeds to step S208 described above, and the current RT state is updated to “RT3”, and then stored in the RAM 110 in step S210. The value of RT3CNT is set to “64”. Note that when the CPU 106 determines that the re-gamer a is not established (NO) at step S212 described above, when it is determined at step S216 that the current RT state is not “RT1” or “RT2”, or If it is determined in step S218 that the re-gamer c is not established (NO), the current RT state is maintained.

  As described above, the CPU 106 clears the value of the number of payouts (step S220) after the RT state is appropriately shifted according to the type of re-game player established by the processing of steps S204 to S218 (step S220). The transition processing subroutine is terminated, and the process proceeds to step S190 in FIG.

  Next, in step S200 described above, if the CPU 106 determines that no replaying combination has been established (NO), whether any of the small combination 1, the small combination 2a to 2c, or the small combination 3 has won a prize. It is determined whether or not (step S222). If it is determined that any small combination is established (YES), the CPU 106 pays out a medal corresponding to the small combination won according to the payout information shown in FIG. The value is updated to the value of the number of sheets (step S224), and the RT transition process is terminated. On the other hand, when the CPU 106 determines in step S222 that none of the small roles has been won and the game result has been lost (NO), the CPU 106 selects the small role 1 stored in the RAM 110. It is determined whether or not the corresponding winning flag is turned on (step S224).

  When the CPU 106 determines that the winning flag corresponding to the small role 1 has been turned on (YES), it means that the small role 1 has been missed, and then whether or not the current RT state is “RT1”. Is determined (step S228). When the CPU 106 determines that the current RT state is “RT1” (YES), the current RT state is updated from “RT1” to “non-RT” (step S230), and the process proceeds to step S220. After clearing the payout number count value, the RT transition processing subroutine is terminated, and the process proceeds to step S190 in FIG. Also, when it is determined in step S226 described above that the winning flag corresponding to the small role 1 has been turned off (NO), or when it is determined in step S228 that the RT state is not “RT1” (NO). Shifts to the process of step S220 while maintaining the current RT state.

  As described above, the CPU 106 controls the game in the slot machine 10 by repeatedly performing the processes shown in FIGS. In the course of one game, first, the lottery information is transmitted from the main control circuit 100 to the sub-control circuit 200 (FIG. 19, step S76), and then the stop switch is operated. Stop operation information is transmitted every time (FIG. 20, step S90), and when all reels are stopped, all reel stop signals are transmitted (FIG. 20, step S96), then game result information, game state information, and RT3CNT values Is transmitted (FIG. 21, step S122).

[Description of control processing in sub-control circuit]
Next, with reference to the flowcharts shown in FIGS. 25 to 28, the notification / effect process executed in the sub control circuit 200 will be described. Here, FIG. 25 is a flowchart showing the contents of the processing related to the ART game which is executed mainly when the role lottery information is received. FIG. 26 is a flowchart showing the contents of the lottery process for determining whether or not to shift to the ART game and the switching control of various effects performed mainly when the game result information is received. FIG. 27 is a flowchart showing the contents of a process related to a chance effect that informs whether or not to shift to the ART game period. Further, FIG. 28 is a flowchart showing the contents of the processing relating to the extension of the ART game period.

<Explanation of notification / production process>
The contents of the notification / effect process will be described with reference to the flowchart shown in FIG. This notification / production process is a process that is periodically executed.
First, the CPU 206 shown in FIG. 4 determines whether or not the chance effect flag stored in the RAM 210 is on (step S300). This chance effect flag is a flag indicating whether or not the chance effect is currently being performed. When the chance effect flag is on, it indicates that the chance effect is being performed. The on / off state of the chance effect flag is stored in the RAM 210. If the chance effect flag is on (YES), the CPU 206 performs a process during the chance effect described later with reference to FIG.

  If it is determined in step S300 described above that the chance effect flag is off (NO), the CPU 206 determines whether or not the role lottery information has been received from the main control circuit 100 (step S302). When the CPU 206 determines that the winning lottery information has not been received (NO), the CPU 206 performs processing when receiving game result information and the like described later with reference to FIG. On the other hand, when the CPU 206 determines that the winning lottery information has been received (YES), the CPU 206 next determines whether or not the ART flag is on (step S304). This ART flag is a flag indicating whether or not an ART game is currently being performed. If it is ON, it indicates that an ART game is being performed.

  When the CPU 206 determines in step S304 that the ART flag is on (YES), the lottery result number derived in the lottery performed in the main control circuit 100 is determined based on the received lottery information. Recognize (step S306). Next, the CPU 206 determines whether or not the lottery result number derived in the role lottery is any of “7” to “9” (step S308). If it is determined that the lottery result number is any one of “7” to “9” (YES), the CPU 206 performs a first stop operation to win the small role 2a according to the recognized lottery result number. A stop switch to be performed (right, middle or left, see FIG. 10) is notified to the player (step S310). Then, the notification / effect process is terminated and another control process is executed.

  If the CPU 206 determines in step S308 that the lottery result number derived in the role lottery is not any of “7” to “9” (NO), the lottery result derived in the role lottery is next. It is determined whether the number is any one of “11” to “16” (step S312). When it is determined that the lottery result number is any one of “11” to “16” (YES), the CPU 206 determines the stop switch 37L for establishing the re-gamer a according to the recognized lottery result number. The operation order of 37C and 37R (see FIG. 11A) is notified to the player (step S314). Then, the notification / effect process is terminated and another control process is executed.

  Further, when the CPU 206 determines in step S312, that the lottery result number derived in the role lottery is not any of “11” to “16” (NO), the lottery result derived in the role lottery is next. It is determined whether the number is any one of “17” to “22” (step S316). When it is determined that the lottery result number is any one of “17” to “22” (YES), the CPU 206 determines the stop switch 37L for establishing the re-game combination b according to the recognized lottery result number. The operation sequence of 37C and 37R (see FIG. 11B) is notified to the player (step S318). Then, the notification / effect process is terminated and another control process is executed. If the CPU 206 determines in step S316 that the lottery result number derived in the role lottery is not any of “17” to “22” (NO), the CPU 206 ends the notification / effect process as it is, The control process is executed.

  On the other hand, when the CPU 206 determines that the ART flag is off (NO) in step S304 described above, it determines whether or not the current gaming state is “BB gaming” (step S320). . When the CPU 206 determines that the current gaming state is “BB gaming” (YES), the lottery result number derived in the winning lottery is recognized based on the winning lottery information received from the main control circuit 100. (Step S322). Next, the CPU 206 determines whether or not the lottery result number derived in the role lottery is any of “3” to “5” (step S324). If it is determined that the lottery result number is any of “3” to “5” (YES), the CPU 206 performs a first stop operation in order to win the small combination 2a according to the recognized lottery result number. A stop switch (see FIG. 10) to be notified is notified to the player (step S326). Then, the notification / effect process is terminated and another control process is executed.

  On the other hand, when the CPU 206 determines in step S320 that the current gaming state is not “BB gaming” (NO), the lottery result number derived in the role lottery is “3” to “3” in step S324. When it is determined that it is neither “5” (NO), the notification / effect process is terminated as it is, and another control process is executed.

  By performing the above processing, when the lottery result numbers “7” to “9” are derived in the role lottery during the ART game, the type of stop switch to be subjected to the first stop operation for winning the small role 2a is determined. Since the notification is made, the player can reliably win the small combination 2a by operating the notified stop switch first. Further, during the ART game, when the lottery result numbers “11” to “16” are derived in the role lottery, the re-game player a is selected. When the lottery result numbers “17” to “22” are derived, the re-game is selected. The operation order of the stop switches in which the combination b is established is notified. For this reason, if the player operates the stop switch in accordance with the notified order, the player can be surely established the re-game player a or the re-game player b.

  That is, when the RT state is “non-RT”, the re-game player a can be surely established and shifted to “RT2”. In addition, since the re-gamer a or the re-gamer b is established, the establishment of the re-gamer c can be avoided, so that the current RT state (“non-RT”, “RT1” or “RT2”) can be avoided. The state can be maintained and the transition to the “RT3” state can be avoided (see FIG. 11).

<Description of processing when receiving game result information, etc.>
Next, using the flowchart shown in FIG. 26, a description will be given of notification / effect processing performed when game result information or the like is received from the main control circuit 100. When the sub-control unit 200 receives game result information from the main control circuit 100, the sub-control unit 200 mainly performs control related to start / end determination of various effects, lottery of whether to shift to ART games, and roadwork effects. .
First, the CPU 206 determines whether or not game result information, game state information, and RT3CNT values (hereinafter referred to as game result information or the like) have been received from the main control circuit 100 (step S330). When the CPU 206 determines that the game result information or the like has not been received (NO), the notification / effect process is terminated and another control process is executed.

  On the other hand, if it is determined that game result information or the like has been received (YES), the CPU 206 updates the game state and RT state in the previous game, and the game state and RT state in the current game (step S332). ). That is, what is stored in the RAM 210 as the gaming state and RT state in the current game is changed to the gaming state and RT state in the previous game, and the gaming state and RT state included in the received game result information, etc. The game state and the RT state in the current game are assumed. This is for comparing changes in various states by comparing the game state and the RT state in the previous game and the current game.

  Next, the CPU 206 determines whether or not the current game state is “general game” (step S334). When it is determined that the current game state is not “general game” (NO), the CPU 206 refers to the received game result information to determine whether or not a special combination has been established in the current game (step S336). ). When the special combination has not been established (NO), the BB game or the RB game has already been performed, and the CPU 206 ends the notification / effect process and executes another control process. On the other hand, when the special combination is established (YES), the special game is started from the next game, so the CPU 206 turns off the ART flag (step S338). And CPU206 starts the effect for special games with the display apparatus 70, the speakers 64L and 64R, and the top effect lamp 72 (step S340), complete | finishes an alerting | reporting and effect process, and performs another control process.

  When the CPU 206 determines that the current gaming state is “general gaming” (YES) in step S334 described above, the previous gaming state is “BB gaming” or “RB gaming” (ie, a special gaming state). It is judged whether or not (step S342). When the CPU 206 determines that the previous game state was the special game state (YES), the special game has ended, and the general game is started from the next game. Then, the roadwork effect screen shown in FIG. 14 is displayed. At this time, the CPU 206 displays the same number of globe images as the number of pieces of transition information (see FIG. 13) stored in the RAM 210 at the display positions (G1 to G4) according to the determination order (step S344). Then, the CPU 206 ends the notification / effect process and executes other control processes.

  Next, in step S342 described above, when the CPU 206 determines that the previous gaming state was not the special gaming state (NO), it is determined whether or not the ART flag stored in the RAM 210 is on. (Step S346). When it is determined that the ART flag is turned on (YES), the CPU 206 determines the end of the ART game period, determines the extension period of the ART game period, and controls various effects performed during the ART game period. ART game control processing for the purpose is performed (step S348). The contents of this ART game control process will be described later in detail with reference to FIG. When the ART game control process in step S348 is completed, the CPU 206 ends the notification / effect process and executes another control process.

  Next, in step S346 described above, when the CPU 206 determines that the ART flag is turned off (NO), is the small game 1 won in the current game with reference to the received game result information? It is determined whether or not (step S350). When the CPU 206 determines that the small role 1 has won the role lottery (YES), the CPU 206 performs an ART transfer lottery (step S352). Here, it is determined that the player wins with a probability of 1/250 and shifts to the ART game period. The conditions for performing the ART transfer lottery are when the game state is “general game” and the small role 1 wins in a state where no chance effect is performed.

  When the CPU 206 performs the ART transfer lottery, the CPU 206 next determines whether or not it has been won (step S354). When it is determined that the ART transfer lottery has been won (YES), the transfer information whose value is “1” is stored in the RAM 210 (step S356), and when it is determined that the ART has not been won (NO), the value is “0”. "Is stored in the RAM 210 (step S358). At this time, the transfer information is stored in the RAM 210 in association with the order (decision order) in which the ART transfer lottery is performed. For example, when the migration information already stored in the RAM 210 has the contents shown in FIG. 13, the migration information is stored in association with the determination order “5”. Next, the CPU 206 additionally displays one glove image on the roadwork effect screen shown in FIG. 14 due to the ART transfer lottery (step S360). At this time, the globe image is displayed at a display position corresponding to the determination order of the transition information corresponding to the globe image.

  Next, the CPU 206 determines whether or not the current RT state is “RT3” (step S362). If the CPU 206 determines that the current RT state is “RT3” (YES), the CPU 206 then checks the remaining number of games in RT3 with reference to the value of RT3CNT received from the main control circuit 100 (step S364). ). Then, the CPU 206 determines whether or not the value of RT3CNT matches the number of displayed globe images (which is also the number of migration information stored in the RAM 210) (step S366). If it is determined that the remaining number of games in RT3 matches the number of displayed globe images (YES), the CPU 206 turns on the chance effect flag stored in the RAM 210 (step S368), and the display device The chance effect screen shown in FIG. 15 is displayed at 70 (step S370). Then, when the process of step S366 is completed, the CPU 206 ends the notification / effect process and executes another control process.

  When the CPU 206 determines that the current RT state is not “RT3” (NO) in the determination process of step S362, or the remaining number of games in RT3 is displayed in the determination process of step S366. If it is determined that the number of glove images does not match (NO), the CPU 206 ends the notification / effect process as it is, and executes another control process.

<Explanation of chance production process>
Next, the contents of the chance effect process will be described using the flowchart shown in FIG. The process related to the chance effect shown in this figure is executed when the CPU 206 determines in step S300 that the chance effect flag is on. If it is determined in step S300 in FIG. 25 that the chance effect flag is ON, the chance effect screen shown in FIG. 15 is displayed on display device 70 by the process in step S368 shown in FIG. ing.

  First, the CPU 206 determines whether or not role lottery information has been received from the main control circuit 100 (step S380). When the CPU 206 determines that the winning lottery information has been received (YES), the CPU 206 displays the glove image displayed at the position of G1 (the highest image) among the glove images displayed on the chance effect screen shown in FIG. Erase the display of the previous globe image. Further, when globe images are displayed after G2, their display positions are shifted one by one to the left (G1 side) (step S382). Then, the CPU 206 starts rotation display of the image reels LR, CR, and RR shown in FIG. 15 (step S384), and ends the process related to the chance effect in FIG.

  If the CPU 206 determines in step S380 described above that the lottery information has not been received from the main control circuit 100 (NO), it is next determined whether stop operation information has been received from the main control circuit 100. (Step S386). When the CPU 206 determines that the stop operation information has been received (YES), the image reels LR, CR, and RR shown in FIG. 15 are rotated and displayed by the process of step S384 described above, and the CPU 206 displays the stop operation information. , The rotation display of the image reels LR, CR, RR is sequentially stopped (step S388).

  That is, if the value of the transition information corresponding to the glove image deleted in step S382 is “1”, the CPU 206 stops the “ART” symbol for the image reel corresponding to the stop switch that has been operated to stop. That is, when the rotation display of the image reels LR, CR, RR is stopped, the “ART” symbol is displayed on all the image reels. In addition, when the value of the transition information is “0”, during the first and second stop operations, the “ART” symbol or the “losing” symbol is stopped for the image reel corresponding to the stop switch that has been operated to stop. Whether to display is determined by lottery, and the determined symbol is stopped and displayed. When the “ART” symbol is displayed on the two image reels that have already stopped when the third stop operation is performed, the image reel corresponding to the stop switch that has been operated for the third stop is displayed. , “Lose” symbol is stopped and displayed. On the other hand, when the “losing” symbol is displayed on both of them, or when the “losing” symbol is displayed on one of the symbol reels, the image reel corresponding to the stop switch that has been subjected to the third stop operation is displayed. The “ART” symbol or the “losing” symbol is to be stopped and displayed by lottery, and the determined symbol is stopped and displayed. And if the process of step S388 is performed, CPU206 will complete | finish the process regarding the chance effect of FIG. 27, and will perform another process.

  When the CPU 206 determines in step S386 described above that the stop operation information has not been received from the main control circuit 100 (NO), it is determined whether or not an all-reel stop signal has been received from the main control circuit 100 (step S386). S390). When all reel stop signals are received (YES), it is determined whether the value of the earliest transition information (the transition information corresponding to the glove image erased in step S382 described above) is “0” or “1” (step S392). If the value of the earliest migration information is “1” (YES), the ART flag is turned on (step S394), and the earliest migration information is deleted (step S396). On the other hand, when the value of the earliest migration information is “0” (NO), the process immediately proceeds to step S396, and the earliest migration information is deleted. After deleting the earliest migration information by this process, if the migration information stored in the RAM 210 remains next, the CPU 206 advances the determination order of the migration information one by one (step S398). And CPU206 complete | finishes the process regarding the chance effect of FIG. 27, and performs another process.

  If the CPU 206 determines in step S390 described above that the all reel stop signal has not been received from the main control circuit 100 (NO), it is next determined whether or not game result information has been received from the main control circuit 100. Judgment is made (step S400). When the CPU 206 determines that game result information or the like has not been received (NO), the process related to the chance effect in FIG. 27 is terminated and another control process is executed. On the other hand, when the CPU 206 determines that the game result information or the like has been received (YES), the CPU 206 refers to the received game result information to determine whether or not a special combination has been established in the current game (step). S402). When it is determined that the special combination is established (YES), the special game effect is started (step S404).

  When the CPU 206 determines that the special combination is not established (NO) in the process of step S402 described above, it is next determined whether or not the ART flag is turned on (step S406). When the CPU 206 determines that the ART flag is on (YES), the value of ARTG stored in the RAM 210 is set to “30” (step S408), and the display device 70 is displayed as shown in FIG. ) An effect screen during ART game is displayed (step S410). At this time, if the transition information stored in the RAM 210 remains, the glove image corresponding to the transition information is displayed on the roadwork effect screen displayed on the display device 70 after the ART game period is over. It will be.

  If the CPU 206 determines that the ART flag is turned off (NO) in step S406 described above, it determines whether the migration information is still stored in the RAM 210 (step S412). When determining that the migration information is not stored in the RAM 210 (NO), the CPU 206 displays the roadwork effect screen shown in FIG. 14 on the display device 70 (step S414). In this case, since the migration information is not stored in the RAM 210, the globe image is not displayed on the roadwork effect screen.

  As described above, when the effect during the special game is started in step S404, or the ART game screen is displayed in step S410, or the roadwork effect screen is displayed in step S414, the CPU 206 turns off the chance effect flag. (Step S416), the process related to the chance effect in FIG. 27 is terminated and other processes are performed. On the other hand, if the CPU 206 determines in step S412 that the transition information is still stored in the RAM 201 (YES), the process related to the chance effect in FIG. 27 is terminated while the chance effect flag is kept on. Thereby, the chance effect is executed again in the next game.

  As described above, during the chance effect, when the player operates the start lever 36 and one game is started, the three image reels LR, CR, and RR displayed on the display device 70 are rotated and displayed. Every time the player operates the stop switch, the rotation display of the corresponding image reel is stopped, all the stop switches are operated, and all three image reels LR, CR, RR are stopped and displayed. By displaying the “ART” symbol on the image reel, the player is notified of the transition to the ART game period. Moreover, since this chance effect is performed by the number of globe images displayed on the screen of the display device 70, the fact that the globe image is displayed on the display device 70 means that the chance effect is performed. It can be said that the number represents the number of times the chance effect is performed.

<Description of ART game control processing>
Next, the contents of the ART game control process executed in step S348 shown in FIG. 26 will be described using the flowchart shown in FIG.
If the CPU 206 determines that the ART flag is turned on (YES) in the determination processing in step S348 of FIG. 26, the CPU 206 first determines whether or not the extra game flag is turned on (step S420). ). This extra game flag is turned on when an extra (extension) of the ART game period is determined during the ART game period, and is on while a game for the decided extra period (determined by the number of games) is being performed. If the state is maintained and a game is played for the added period, the game is turned off.

  When determining that the extra game flag is off (NO), the CPU 206 subtracts “1” from the value of the ARTG stored in the RAM 210 (step S422). The initial value of this ARTG is set to “30” by the process of step S408 in the game in which the ART flag is turned on in step S394 of FIG. Next, the CPU 206 determines whether or not the value of the ARTG has become “0” (step S424). When the CPU 206 determines that the value of the ARTG has become “0” (YES), the CPU 206 stores the value in the RAM. The on / off state of the ART flag being set is turned off (step S426), and the roadwork effect screen shown in FIG. 14 is displayed on the display device 70 (step S428). At this time, when the migration information is stored in the RAM 210, the globe images are displayed by the number of the stored migration information.

  On the other hand, when the CPU 206 determines that the value of the ARTG is not “0” (NO) in the process of step S424 described above, the game in the ART game screen shown in FIG. “1” is subtracted from the remaining number of games in the ART game period displayed in the number display area CNT (step S430). Then, the CPU 206 performs processing for determining whether or not to extend the ART game period. First, the CPU 206 determines whether or not any of the lottery result numbers “4” to “6” is derived by the role lottery in the current game (step S432). If it is determined that none of the lottery result numbers “4” to “6” has been derived (NO), the CPU 206 ends the ART game control process and performs other processes. On the other hand, when it is determined that any one of the lottery result numbers “4” to “6” has been derived (YES), the CPU 206 determines whether or not the small role 1 has won a prize in this game. (Step S434). When it is determined that the small role 1 has won (YES), the CPU 206 ends the ART game control process and performs other processes.

  On the other hand, when the CPU 206 determines that the small role 1 has not won, that is, the small role 1 has been missed (NO), the lottery result number “6” has been derived in the role lottery (ie, the small role 1 It is determined whether or not 1 is won alone (step S436). When the CPU 206 determines that the lottery result number “6” has been derived (YES), the number of games for extending the ART game period is determined by lottery based on the extended lottery table shown in FIG. That is, one random number is generated within a numerical value range of 0 to 255, and it is determined which of the added game times EG shown in FIG. Then, the value of the corresponding extra game number EG is stored in a predetermined storage area of the RAM 210.

  At this time, based on the symbol number of each reel that is stopped and displayed in the display window 22 included in the game result information received from the main control circuit 100, the chance eye (“red” "7-blue cherry-watermelon" or "blue 7-blue cherry-watermelon") is stopped and displayed, and if the chance eye is displayed, the "chance eye stop display" field in FIG. When the chance item is not displayed, the lottery table in the “chance eye non-stop display” column is referred to.

  When the extra game number EG is determined by the extended lottery in step S438, the CPU 206 next determines whether or not the determined extra game number EG exceeds “0” (step S440). If the determined additional game count EG is “0”, that is, it is determined not to extend the ART game period (NO), the ART game control process of FIG. 28 is terminated and other processes are performed. On the other hand, when the extra game number EG exceeding “0” (that is, any of 10, 30, 60, 90, 10000) is determined (YES), the value of the variable add stored in the RAM 210 is determined. Is set to “0” (step S442). This variable add is a variable for counting the number of games played during the extension period.

  Next, the CPU 206 turns on the on / off state of the extra game flag stored in the RAM 210 (step S444), and determines whether or not the chance eye is stopped and displayed along any valid line (step S444). Step S446). When CPU 206 determines that the chance eye is stopped and displayed (YES), it executes the above-described privilege effect (step S448). That is, an effect suggesting that either the determination of the extra game number EG exceeding “0” or the winning of the BB role in the role lottery has been performed is executed, and the additional game exceeding “0” is performed at the end of the effect. An effect indicating that the number of times EG has been determined is executed. Then, the CPU 206 “adds” a number indicating the remaining number of games in the ART game period displayed in the game number display area CNT on the ART game screen shown in FIG. 16A as shown in FIG. 16B. (Step S450). Thereby, the ART game in the extended period is started from the next game. When the above process is completed, the CPU 206 ends the ART game control process of FIG. 28 and performs other processes. In step S446, when the CPU 206 determines that the chance is not stopped and displayed (NO), the process proceeds to step S450 without performing the privilege effect by the process in step S448.

  On the other hand, when the CPU 206 determines in step S436 that the lottery result number “6” has not been derived (NO), that is, the lottery result number “4” or “5” has been derived, any valid line is determined. It is determined whether or not the chance eye is stopped and displayed (step S452). When CPU 206 determines that the chance eye is stopped and displayed (YES), it executes a privilege effect slightly different from the privilege effect executed by the process of step S448 (step S454). That is, first, similar to the bonus effect executed in step S448, an effect is performed that suggests that either the determination of the extra game number EG exceeding “0” or the winning of the BB role in the role lottery has been performed. However, at the end of the effect, an effect indicating that the BB role is won in the role lottery is performed. Then, the CPU 206 ends the ART game control process of FIG. 28 and performs other processes. If the CPU 206 determines in step S452 that the chance item has not been stopped (NO), the ART game control process of FIG. 28 is terminated without performing the bonus effect by the process of step S454. Perform the process.

  When the extra game flag is turned on by the processing of step S444, the ART game in the extended period is started from the next game. That is, in the process of step S420 described above, it is determined that the extra game flag is on (YES). As a result, the CPU 206 subtracts “1” from the value of the extra number of games EG stored in the RAM 210 and adds “1” to the value of add (step S456). Next, the CPU 206 determines whether or not the value of add has become “10”, “30”, “60”, or “90” (step S458). When the CPU 206 determines that the value of add has become any one of “10”, “30”, “60”, or “90” (YES), the value of the number of added games EG is next “0”. It is determined whether or not (step S460).

  If the CPU 206 determines that the value of the extra game number EG has become “0” (YES), it executes a continuation effect indicating that the extension period continues or ends, and the extension period ends at the end of the effect. This is notified (step S462). Then, the value of the extra game flag stored in the RAM 210 is turned off (step S464), and the character “add” displayed in the game number display area CNT of the ART game screen shown in FIG. Then, the value is changed to a number indicating the value of ARTG (the remaining number of games in the ART game period) stored in the RAM 210 (step S466). Thereafter, the CPU 206 ends the ART game control process of FIG. 28 and performs other processes. On the other hand, if CPU 206 determines in step S460 that the value of the extra number of games EG is not “0” (NO), it executes a continuation effect indicating that the extended period continues or ends, At the end of the performance, a notification indicating that the extension period continues is performed (step S468). Then, the CPU 206 ends the ART game control process of FIG. 28 and performs other processes.

  When the CPU 206 determines in step S458 described above that the value of add is not any of “10”, “30”, “60”, or “90” (NO), the process immediately proceeds to FIG. The ART game control process is terminated and other processes are performed.

  As described above, when the ART game period is started, when each game ends, the remaining number of games in the ART game period is subtracted (step S422), and the remaining number of games is displayed in the game number display area on the ART game screen. It is displayed on CNT (step S430). When the remaining number of games in the ART game period becomes “0” (step S424, YES), the ART game period ends (step S426). Further, in the game during the ART game period, if the small role 1 is won by the role lottery (step S436, YES) and the small role 1 is missed (step S434, NO), the extended lottery is performed. The number of extra games EG is determined (step S438).

  If the determined number of extra games EG exceeds “0” (step S440, YES), the extra game flag is turned on and the game in the extended period of the ART game period is started from the next game. (Step S420, YES).

  As a result, when the chance chance is stopped and displayed during the ART game period, there is a possibility that a bonus effect may be executed (even if the chance eyes are stopped and displayed, the extra number of games EG is set to “0” in the extended lottery). If it is determined, the bonus effect is not executed.) If the bonus effect is executed, either the extension of the ART game period is determined or the BB role is won in the role lottery. Since it is in an advantageous state for the player, it is possible to face the bonus production with an interest in which bonus will be given while being relieved.

  When the extension of the ART game period is determined (step S444), a game in the extension period is performed from the next game (step S420, YES). During this period, for example, the remaining extension period is given to the player. The number of games is not notified (step S450). Thereby, since the player does not know how long the extension period will continue, the player will play with a sense of expectation and tension, and as a result, there is a possibility that the interest of the game can be enhanced.

  Furthermore, in the extended period, when the number of game times of 10 times, 30 times, 60 times, and 90 times is performed (step S458, YES), in order to perform a continuous effect of whether the extended period continues or ends.

Sometimes, it is determined whether or not the chance chance is stopped and displayed on the active line, and if it is stopped and displayed, the ART game control process of FIG. 28 may be ended after performing the bonus effect. However, in this case, in the case of the bonus effect, first, as in the bonus effect executed in steps S448 and S452, either the determination of the extra game number EG exceeding “0” or the winning of the BB role in the role lottery is performed. An effect suggesting that this is performed, but at the end of the effect, an effect indicating that the ART game period has not been extended is performed.

  In addition, in the determination process of steps S432, S434, and S436, the small role 1 was missed, and the extended lottery was performed only when the small role 1 was elected alone in the role lottery, but the small role 1 was missed. Or, regardless of winning a prize, an extended lottery may be performed if the small role 1 is won by the role lottery alone. In this case, for example, the determination process in step S434 in FIG. 28 may be omitted, and when the determination result in step S432 becomes YES, the process immediately proceeds to the determination process in step S436.
