Description

  The present invention relates to a slot machine for determining a game result by a combination of symbols drawn on a reel displayed at that time after a player inserts a game medium, rotates a reel, and stops.

  Conventionally, a slot machine is widely known as one of gaming machines. In this type of slot machine, when a game medium such as a medal or a game ball is inserted by a player and then the start switch is operated, one game is rotated, and a plurality of symbols each having a plurality of symbols are drawn. Rotate the reel. When each stop switch provided for each reel is operated, the corresponding reel is stopped, and when all the reels are stopped, the game result is determined by the combination of symbols shown to the player. At this time, if the combination of symbols stopped and displayed along the effective line defined in the area for displaying the symbols drawn on each reel matches the symbol combination corresponding to some role, the symbol combination The role corresponding to is established. When a combination is established, a privilege corresponding to the combination is given to the player, and when no combination is established, one game is finished without any privilege being granted.

  In addition, the slot machine described above performs a role lottery that determines whether or not one of a plurality of predetermined types of winning combination has been won, triggered by the start of rotation of a plurality of reels by a player. Is going. Then, when the player operates the stop switch to stop the reel, the reel stop control is performed so that the symbol combination in accordance with the result of the above-described combination lottery is stopped and displayed along the effective line. Each of the above-described multiple types of combinations has different contents of a privilege to be given to the player when established. That is, in general, a small role for paying out a predetermined number of game media, a re-game player who can perform the next game only once without newly inserting a game media, and a predetermined end condition from the next game. There are special roles that can be used for special games in which the winning probability of a specific role in the role lottery is improved until it is established.

  Further, in the slot machine described above, a random number lottery is performed separately from the role lottery at the end of the special game, and if the random number lottery is won, it is advantageous for the player who is “notification mode game” until the next special role is established. Have been proposed (see Patent Document 1). In the slot machine described in Patent Document 1, in a game that is not a special game (hereinafter, this game is referred to as a general game), when a specific combination is won by a combination lottery, three stop switches respectively corresponding to three reels are operated. Any one of the orders (all six) is determined by random number lottery. Then, when the stop switch is operated in the determined operation order, reel stop control is performed to align the symbol combination corresponding to the specific combination on the effective line, and when operated in the other operation order, it is performed on the effective line. Reel stop control is not performed.

  And if it transfers to the "notification mode game" mentioned above, when a specific combination is won by a combination lottery, a lottery result about an operation order will be notified to a player beforehand. Thereby, the player can arrange the symbol combinations corresponding to the specific combination on the effective line only by operating the stop switch according to the notified operation sequence. In addition, as each game is played, the number of inserted medals and the number of paid out medals in the past hour are checked. If the number of paid out medals exceeds three times the number of inserted medals, the “notification mode game” is interrupted, When the payout number is less than 2.5 times the inserted number, the “notification mode game” is resumed. Thereby, the device which is not excessively intriguing is given.

  Also, in a slot machine similar to that described above, when a special game is over, there are those that shift to the “RT operation state” in which the winning probability of a re-gamer is increased in a role lottery for a predetermined number of games (for example, 1000 games). It has been proposed (see Patent Document 2). In this “RT operation state”, the probability of winning a re-gamer in the role lottery is increased, and the probability of being lost in the role lottery is reduced accordingly, so that the player can advantageously play the game. . Further, in the slot machine described in Patent Document 2, when a specific combination (for example, cherry) is established in the “RT operation state”, the “RT operation state” is terminated.

  Therefore, in the slot machine described in Patent Document 2, when a specific combination is won in the combination lottery, a specific combination is obtained by notifying the player in advance that the operation timing of the stop switch is adjusted. The establishment of can be avoided. The number of notifications is determined by lottery, and a value (any one of 0 to 5) to be subtracted from the current number of notifications when one notification is performed is also determined by lottery. In this way, the value for decreasing the number of notifications is changed, so that the interest in the game is improved.

  By the way, the slot machine described in Patent Document 1 includes an effect output device such as a lamp, a speaker, and an image display device. While the ratio of the number of acquired sheets to the number of inserted games is displayed, during this time, there is no effect that improves the interest of the game. Certainly, during the “notification mode game”, it can be said that the player is in an advantageous state, so even if such an effect is not performed, the player's willingness to play may not decrease, Once the “notification mode game” is started, the “notification mode game” continues until the next special role is established, so that a simple game operation (medal insertion operation, start switch and stop switch operation) Etc.), and there is a risk that the player will get bored.

  Further, in the slot machine described in Patent Document 2, when the “RT operation state” is entered, the stage (background image) is fixed to “special”, and when a specific combination is won in the combination lottery, the number of notifications is “ It is informed that a specific combination has been won on the condition that it is “1” or more. However, as the production element that increases the player's tension about the possibility that the “RT operation state” will continue, only the remaining number of notifications is displayed. It's not enough.

  Further, in the slot machine described in Patent Document 1, the “notification mode game” is interrupted when the ratio of the number of obtained coins to the number of inserted medals exceeds a predetermined value so as not to excessively provoke the player's gambling. ing. For this reason, there is a problem that during the “notification mode game”, even if an effect for improving interest is performed, it is difficult to perform an effect with continuity. For example, in order to have continuity of production, it is assumed that the production is continued even when the “notification mode game” is interrupted. However, at this time, if the player does not depend on the notification and happens to have established a specific combination, the player is informed that the “notification mode game” is interrupted. That is, although the “notification mode game” is interrupted, the player will realize that the performance in the “notification mode game” is being performed, which may cause the player to turn white. .

  The present invention has been made in view of the above problems, and a player's sense of tension regarding the possibility that the advantageous game will continue while a game more advantageous to the player than the general game is being performed. Another object of the present invention is to provide a slot machine that can improve the fun of the game by performing an effect that further enhances the expectation.

  Further, in the case of controlling the execution of the advantageous game described above so as not to excessively arouse the gambling feeling of the player, the interest of the performance performed during the execution of the advantageous game is not impaired. It aims to provide a slot machine.

In order to solve the above-described problems, the present invention is such that when a predetermined number of game media are inserted, a plurality of reels on which a plurality of types of symbols are displayed are in a rotatable state, and the plurality of reels are rotated. A slot machine that pays out a predetermined number of the game media when the symbol combination displayed along the winning line when all reels stop corresponds to a predetermined role,
A role lottery means for determining any one or more of a plurality of types of roles by one role lottery;
A plurality of stop instruction means provided corresponding to each of the plurality of reels and instructing a corresponding reel to stop in response to an external operation;
When the stop instruction is issued from any of the plurality of stop instruction means, the stop instruction is made so that the symbol combination corresponding to the winning combination in the lottery by the winning lottery means stops along the winning line. Reel stop control means for stopping the reel corresponding to the stop instruction means,
In the combination lottery, when the predetermined combination is won, the reel stop control unit stops the symbol combination corresponding to the predetermined combination along the winning line. An informing means for informing about operation;
A notification control means for performing notification by the notification means between a predetermined start condition being satisfied and a predetermined end condition being satisfied;
An establishment process display means for displaying a process in which the end condition is established while the notification control means performs notification by the notification means;
The notification control means includes
After the predetermined start condition is established, an end lottery means for performing an end lottery that becomes an element of establishment of the end condition each time a specific combination is won in the combination lottery,
A winning probability setting means for setting a winning probability selected from a plurality of types of winning probabilities of the end lottery according to a predetermined selection probability as a winning probability of an end lottery performed by the ending lottery means;
Winning number counting means for counting the number of winning times of the end lottery;
When the number of winnings counted by the winning number counting means reaches a predetermined number, it is considered that the end condition is satisfied,
The establishment process notifying means includes
Notifying the selection probability information corresponding to the selection probability and / or information indicating the number of times the winning lottery has been won, or any one of the information, and the lottery result every time the closing lottery is performed A slot machine characterized by

  Here, the “plural stop instruction means” corresponds to, for example, a stop switch in a conventional slot machine. In addition, “notification regarding operation of a plurality of stop instructing means” means notification indicating the order in which each stop switch should be operated, or a symbol constituting a symbol combination corresponding to a predetermined combination by a reel stop control. This is a notification indicating that the stop switch should be operated at a timing at which it can be stopped at the line position. In addition, the “predetermined start condition” at which the notification is started is, for example, when a predetermined combination is won in a combination lottery, or when a predetermined combination is established, For example, when a predetermined combination is not established, or when it is determined to start notification by random number lottery that is triggered by the occurrence of these events. Further, the “selection probability” is, for example, a probability of selecting each of a plurality of types of winning probabilities, and among the plurality of types of winning probabilities, the winning probability to be excluded from selection is selected. The probability can be set to “0”.

  In the slot machine according to the present invention, when a predetermined start condition is established, every time a predetermined combination is won in the lottery, a symbol combination corresponding to the predetermined combination is stopped and displayed along the winning line, and a predetermined number of combinations are displayed. The notification regarding the operation of the plurality of stop instruction means that the game medium is to be paid out is started. During the period in which the notification is performed, if the end lottery performed by the end lottery means is won a predetermined number of times, the end is performed because a predetermined end condition is satisfied. That is, the end lottery is an element (establishment element) for satisfying a predetermined end condition. In addition, the winning probability for winning the end lottery is determined based on a selection lottery result based on a predetermined selection probability from a plurality of predetermined winning probabilities. Then, during the notification period described above, the player is notified of the selection probability and the number of times that the end lottery has been won. Here, only one of the selection probability and the number of winning lotteries in the end lottery may be notified. In addition, the lottery result is also notified every time the end lottery is performed.

  In this way, not only gives the player a sense of tension, but also gives the winning probability of the end lottery by notifying the lottery result of the end lottery and the number of wins related to the end condition of the game period in which notification advantageous to the player is performed. By notifying the information indicating the selection probability of the selection lottery performed at the time of determination, it is possible to further give the player a sense of expectation and tension regarding the sustainability of the game period described above. In other words, when the notified selection probability is such that it is easy to select a low winning probability, the player can be expected to have the above-described game period last longer. On the other hand, if the notified selection probability is such that it is easy to select a high winning probability, the player is given a tension that may be won each time the final lottery is performed. be able to. Also, by notifying the probability of selecting one of multiple types of winning probabilities rather than the winning probability of the final lottery, the player is expected to be in a state that is difficult to win the final lottery. It becomes easy and it can make it difficult to reduce a player's willingness to play.

Further, the present invention provides the above slot machine,
The notification control means includes
The number of winning the end lottery at which the end condition is satisfied, and the selection probability for setting the winning probability of the end lottery when the start condition is satisfied and each time the end lottery is won are determined. An end condition storage means for storing the end condition;
The winning probability setting means includes:
The winning probability used in the end lottery is selected and set according to the selection probability specified by the end condition when the start condition is satisfied and when the end lottery is won.

  In the slot machine according to the present invention, whenever a predetermined start condition is established and a predetermined combination is won in the lottery, a notification regarding the operation of a plurality of stop instruction means that the predetermined combination is established is made. When the game is started, the winning probability of the end lottery is selected according to the selection probability defined as the end condition. Thereafter, every time the end lottery is won, the winning probability of the end lottery is selected again according to the selection probabilities determined corresponding to the respective wins. Thereby, the winning probability of the end lottery determined at the start of the game may change every time the end lottery is won. In addition, since the selection probability at the time of selection of the winning probability is notified each time, the expectation degree regarding the sustainability of the above-described gaming period in the player may change, thereby the gaming period described above You can improve your interest.

[Description of the exterior configuration of the slot machine body]
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, which is a symbol display area, displays symbols printed on the outer peripheral surfaces of the three reels 40L, 40C, and 40R that are rotatably provided inside the slot machine 10 at the approximate center of the front panel 20. A window 22 is formed. 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, a total of nine symbols are stopped and displayed on the display window 22 (3 symbols) × 3 (reels). Here, among the three symbols displayed continuously when the reels 40L, 40C and 40R are stopped, the uppermost symbol display position is the upper U, the central symbol display position is the middle M, and the lowermost The symbol display position is set to L in the lower row.

  The display window 22 has four winning lines that cross the reels 40L, 40C, and 40R. The four pay lines are arranged in the display window 22 such as a V-shaped pay line L1 crossing 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 upper stage U, the middle stage M of the middle reel 40C and the lower stage D of the right reel 40R, the diagonally lowering winning line L2, the lower stage D of the left reel 40L, the middle stage M of the middle reel 40C, and the upper stage U of the right reel 40R. An obliquely upward winning line L3 that traverses, a lower stage D of the left reel 40L, a middle stage M of the middle reel 40C, and a mountain-shaped prize line L4 that crosses the lower stage D of the right reel 40R. Thus, each winning line passes through any one of the three symbol display positions (upper U, middle M, and lower D) of the reels 40L, 40C, and 40R.

  Each of the winning lines L1, L2, L3, and L4 is a reference line for determining a symbol combination corresponding to a plurality of predetermined types of roles (described later), and the reels 40L, 40C, and 40R are stopped. The combination of the three symbols stopped and displayed at the symbol display position crossed by the winning line (hereinafter referred to as the effective line) considered to be valid among the four winning lines corresponds to one of the roles. If so, the role is established. That is, among the symbol display positions in the display window 22, the upper U and lower D of the left reel 40L, the middle M of the middle reel 40C, and the upper U and lower D of the right reel 40R are any of the winning lines. Is the symbol display position (hereinafter referred to as the position of the winning line). On the other hand, the middle stage M of the left reel 40L, the upper stage U and the lower stage D of the middle reel 40C, and the middle stage M of the right reel 40R are symbol display positions through which no winning line passes, and these symbol display positions. The symbols that are stopped and displayed are not involved in the determination of the symbol combinations corresponding to the above-described multiple types of combinations.

  In addition to the display window 22, the front panel 20 is provided with a lamp and a display for notifying the player of various information related to the game. Below the display window 22, bet number (betting number) display lamps 24 a, 24 b, 24 c, a credit number display 26, and an acquired number display 28 are provided in order from the left in FIG. 1. The bet number display lamps 24a, 24b, and 24c display the number of medals inserted in one game. That is, when one medal is inserted, only the bet number display lamp 24a is lit, and when two medals are inserted, the bet number display lamps 24a and 24b are lit, and when three medals are inserted. The bet number display lamps 24a, 24b, and 24c are turned on. Here, the slot machine 10 is a so-called three-sheet betting machine in which one game can be performed when three medals are inserted, and the winning lines L1 to L4 are all valid lines. The credit number display 26 is a 2-digit 7-segment display, 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 through which medals can be inserted into the slot machine 10 is provided on the upper right side of the operation panel 30. A medal counter (not shown) is provided inside the medal insertion slot 32. The medal inserted from the medal insertion slot 32 is detected and the number of the medals is counted. 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 various bet switches 34 and 35, the bet number display lamps 24a, 24b, and 24c are sequentially displayed every time a medal is inserted. The winning lines L1 to L4 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 26 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 26.

  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 and displayed on the display window 22 from top to bottom. Three stop switches 37L, 37C, and 37R are provided in the center of the front surface 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 rotational speeds of the three reels 40L, 40C, and 40R reach a constant speed. 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 D. Here, the position where the center of the symbol coincides with the center of the symbol display position is called a fixed position. In the slot machine 10, the reel stop control is performed to adjust the stop position of the symbol so that the symbol always stops at a fixed position when the player stops the corresponding reel by operating the stop switch. Yes.

  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 a small role, a 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. Yes.

  Above the front panel 20, an image display device 70 composed of a liquid crystal display panel is provided. The image display device 70 is not limited to the above-described liquid crystal display panel, and any other image display device can be used as long as the image information and the character information can be visually recognized by the player during the game. The image display device 70 displays a game history, an effect image during a special game, an effect image according to a result of a lottery to be described later, progress of the game (medal insertion → operation of the start switch 36 → reel rotation → It is possible to display an effect image or the like according to the operation of the stop switches 37L, 37C, 37R → all reel rotation stop). Above the image 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. These symbols are composed of 10 types of symbols. In this embodiment, as the types of designs, “pellet” designs using animal pellets as motifs, “ring” designs using motifs as rings, “watermelon” designs using watermelons, and “plums” using plums as motifs The symbols “Bell 1” and “Bell 2” with motifs of different bells, “BAR1” and “BAR2” with motifs of rod-shaped chunks with different shapes, and the number 7 There are a “red 7” symbol and a “white 7” symbol respectively represented in red and white. On the reel tape attached to each of the reels 40L, 40C and 40R, 21 symbols comprising these 10 types of symbols are printed at equal intervals with the contents shown in FIG. No. (hereinafter referred to as symbol number) is assigned in advance. When these reel tapes are attached to the outer peripheral surfaces of the corresponding reels 40L, 40C, and 40R, the symbols of symbol number 1 and symbol number 21 of each symbol array shown in FIG. 2 are continuous.

  When the reels 40L, 40C, and 40R rotate, the three symbols of each reel displayed in the display window 22 are moved and displayed in the direction in which the values of the three consecutive symbol numbers increase. For example, when symbols of symbol numbers 1, 2 and 3 are displayed from the lower stage D to the upper stage U of the reel display window 22, the symbols to be displayed thereafter are symbol numbers 2, 3, 4 → design. Numbers 3, 4, and 5 → Symbol numbers 4, 5, 6, and so on change. When the symbol numbers 19, 20, 21 are displayed, the symbol numbers 20, 21, 1 → symbol numbers 21,1,2 → symbol numbers 1,2,3 →... Until the reel stops, three consecutive symbols out of symbol numbers 1 to 21 are scrolled and displayed cyclically.

The number of games of various games to be played) can be temporarily stored.

  The RAM 110 also stores information indicating the state of the slot machine 10. As will be described later in detail, the state of the slot machine 10 is roughly classified into a gaming state and an RT state. There are four types of game states: general game and MB games 1-3. The RT state indicates a more detailed state when the game state is a general game, and there are three types of states: non-RT, RT1, and RT2. Information indicating the current gaming state and RT state is stored in the RAM 110.

  A random number generator 112 for generating random numbers is also connected to the input / output bus 104. The random number generator 112 generates a random number (integer) within a certain range of numerical values, for example, in the range of 0 to 65535 (2 to the 16th power). You may comprise this random number so that it may generate | occur | produce by the arithmetic processing of CPU106. Further, a motor drive circuit 114 is connected to the input / output bus 104. The motor driving circuit 114 is connected to stepping motors 80L, 80C, and 80R that rotationally drive each of the three reels 40L, 40C, and 40R. 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.

A drive control command issued from the CPU 106 is converted into a drive signal by the motor drive circuit 114, and the drive signal is supplied to the stepping motors 80L, 80C, and 80R. The drive control command includes a rotation speed command, and performs rotation control and stop control of the stepping motors 80L, 80C, and 80R, and also performs rotation speed control. As described above, the CPU 106 controls the rotation and stop of the reels 40L, 40C, and 40R and controls the rotation speed by controlling the stepping motors 80L, 80C, and 80R. Each of the reels 40L, 40C, and 40R is provided with a rotation angle position sensor (not shown) for detecting the rotation angle position of each reel. The rotation angle position sensor is a reel rotation angle position detection circuit 116. It is connected to the. When a signal indicating the rotation angle position of each of the reels 40L, 40C, and 40R is generated from the rotation angle position sensor, the signal is supplied to the reel rotation angle position detection circuit 116, converted into a predetermined signal, and then input / output bus 104. To be supplied. Then, the CPU 106 calculates a symbol number from the supplied rotation angle position, and specifies three symbols of each reel displayed on the display window 22.
In addition to the various switches described above, a connection line 118 is also connected to the interface circuit 102, and the main control circuit 100 is electrically connected to a sub control circuit 200 described below through this connection line 118.

≪Description of sub control circuit≫

[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 FIG. 1 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 operating means 300 and motors 80L, 80C and 80R provided on the reels 40L, 40C and 40R, respectively. The sub-control circuit 200 is electrically connected to the notification means 600 including the speakers 64L and 64R, the image display device 70, and the upper effect lamp 72. The operation unit 300 includes a game start instruction unit 310 including a start switch 36, a stop instruction unit 320 including three stop switches 37L, 37C, and 37R, and bet switches 34 and 35. 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 player's limbs. In addition, the notification unit 600 is not limited to a sound or light notification of the player, but for example, a vibration generator such as a vibrator is provided inside the slot machine 10 to vibrate a specific part. It is possible to make a notification recognized by the player's tactile sense.

≪Description of main control circuit≫
The main control circuit 100 includes a winning lottery means 410, a reel control means 420, a winning determination means 430, a winning lottery probability changing means 440, and a winning processing means 450. The role lottery means 410 determines whether or not one or more of the predetermined roles are won by the role lottery process. The predetermined roles described above are roughly classified into three types: a small role, a replay role, and a bonus role (special role). 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 re-game, and the effective line in the re-game is the same as the effective line in the game in which the re-game 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 game in this embodiment is called a middle bonus game (hereinafter referred to as MB game), and when the number of medals paid out during the MB game exceeds a predetermined number, the end condition is satisfied. ing. In the present embodiment, three types of MB games with different end conditions can be executed. The first MB game (hereinafter referred to as MB game 1) ends when the number of medals paid out exceeds 280, and the second MB game (hereinafter referred to as MB game 2) has a medal payout number of 140. The third MB game (hereinafter referred to as MB game 3) ends when the number of medals paid out exceeds 40. In the slot machine 10, any MB game (not a special game) is a general game.

<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 steps S44 and S46 of a role lottery processing subroutine (see FIG. 14) 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, the combinations that can be established in the slot machine 10 are associated with symbol combinations composed of symbols drawn on the left reel 40L, the middle reel 40C, and the right reel 40R, respectively. This symbol combination means a symbol combination that is stopped and displayed along any of the effective lines L1 to L4, and is referred to when a winning determination means 430 described later makes a winning determination. When these symbol combinations are stopped and displayed along the active line, the corresponding combination is established, and a score corresponding to each combination is awarded to the player.

  That is, when the MB combination 1 is established, the above-described MB game 1 is started from the next game, and when the MB combination 2 is established, the above-described MB game 2 is started from the next game. When either MB combination 3a or MB combination 3b is established, the above-described MB game 3 is started from the next game. When the small combination is established, the number of medals corresponding to the type of the established small combination is paid out to the player. That is, when the small combination 1 is established, two medals are paid out, and when any of the small combinations 2a to 2j and the small combinations 3 to 5 are established, ten medals are paid out. Here, the formation of a small combination, that is, a combination with payout of medals when established, is also referred to as winning. In FIG. 6, “Any” is described as a symbol of the right reel in the small combination 1 and a symbol of the left reel and the right reel in the small combination 4, which indicates an arbitrary symbol. Therefore, for example, in the case of the small combination 4, if “BAR1” stops at the position of the active line related to the middle reel 40C (that is, the middle stage M), the small combination 4 wins at that time. Further, when any of the re-game players a to d is established, the next game becomes a re-game.

  In addition, as will be described in detail later, for the small roles 2a to 2j, a plurality of small roles 2 can be won at the same time in one winning lottery. Whether or not a winning combination can be won depends on the operation order of the stop switches 37L, 37C, and 37R by the player (see FIG. 6B). Similarly, a plurality of re-game players can be won at the same time with one game lottery for the re-game players a to d, and depending on the operation order of the stop switches 37L, 37C, 37R by the player, Either the re-gamer a or the re-gamer b is established.

  Next, the contents of the winning lottery table stored in the ROM 108 will be described with reference to FIG. The part lottery table shown in FIG. 7 shows the contents of the part lottery table used during the general game. (A) shows the contents of the part lottery table used when the RT state is RT2, and (b) shows the contents. The contents of the combination lottery table used at RT1 are shown. The combination lottery table used when the RT state is non-RT has almost the same contents as FIG. 7A, but the lottery result numbers “14” (re-game players a, b, d) and “15” ( The winning value range of “Lose” is slightly different. Further, during the execution of the MB games 1 to 3, since all the small roles are determined to be won without depending on the lottery, there is no role lottery table referred to at this time. Accordingly, since the small combination 5 shown in the payout information shown in FIG. 6 is a combination that can be won only during the MB game, it is not a lottery target in the combination lottery table shown in FIG.

  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 winning numerical value range of the combination lottery table belongs. The number of winning combinations associated with one lottery result number is one or more. For example, in the winning lottery table used during the general game shown in FIG. “5”, “9”, and “10” are each associated with one combination, and lottery result numbers “6” to “8” and “12” to “14” are associated with a plurality of combinations. It is attached. When a lottery result in which a plurality of combinations are associated is derived, it is treated that the plurality of combinations are won at the same time. For example, when the role lottery table shown in FIG. 7A is used, if the random number extracted by the random number extraction unit 412 is “2814”, the random number determination unit 414 determines the lottery result number “6”. ”Is derived, and all of the small roles 2a to 2h and the small roles 2i associated therewith have been won.

  Further, in the winning lottery table used in the non-RT state, in FIG. 7A, the winning numerical value range of the lottery result number “14” is 25385 to 28198, and the winning numerical value range of the lottery result number “15” is 28199. It is ~ 65535. As a result, the winning probability (combination probability) of the re-gamer is 1 / 7.2987 when it is RT2, whereas it is 1 / 7.2980 when it is non-RT. The probability is high. In addition, the winning lottery table referred to at RT1 shown in FIG. 7B shows the winning numbers in the lottery result numbers “1” to “10” (winning probabilities) shown in FIG. 7A. Although it has the same contents as the lottery table, each winning numerical value range of the lottery result numbers “11” to “14” has been greatly expanded to 19219 to 64218, so that the winning combination probability of the re-gamer is about 1 / 1.46. On the other hand, the winning numerical value range of the lottery result number “15” (losing) is reduced to 64218 to 65535, and the probability of the losing is about 1 / 49.76 (about 1/1 for non-RT, RT2). .755).

<Description of reel control means>
The reel control unit 420 includes a reel start unit 422, an operation order determination unit 424, and a reel stop control unit 426, and performs control related to the operation of the reels 40L, 40C, and 40R. The reel starter 422 receives the reel rotation start signal transmitted from the start switch 36 and drives the motors 80L, 80C, 80R to rotate the reels 40L, 40C, 40R. Based on the reel stop signal output from the stop switches 37L, 37C, and 37R, the operation order determination unit 424 determines the type (left / middle / right) of the first, second, and last operated stop switches. . The reel stop control means 426 stops the reels 40L, 40C, 40R according to the reel stop signal transmitted from the stop switches 37L, 37C, 37R. Control processing by the reel starting means 422 is shown in step S74 of a reel fluctuation / stop subroutine (see FIG. 15) described later, and control processing by the reel stop control means 426 is shown in steps S78 to S84 of the subroutine.

  The reel stop control means 426 performs the role lottery within a predetermined limit when stopping the corresponding reels 40L, 40C, 40R according to the operation of the stop switches 37L, 37C, 37R by the player. Control is performed so that the symbol combination according to the result is stopped and displayed along the active line. For example, when a certain stop switch is operated in a state where any combination is won by the combination lottery, the reel stop control unit 426 performs the above operation while the corresponding reel moves (rotates) by a predetermined number of symbols. When the symbols that make up the symbol combination corresponding to the winning combination can reach the symbol stop position where the active line crosses (hereinafter referred to as the position of the effective line), the symbol reaches the position of the active line. Stop the reel when you do. Here, the predetermined number of symbols described above is 5 symbols for all reels during the general game, but during MB game, 2 symbols for the left reel 40L and 5 symbols for the middle reel 40C and the right reel 40R. Become.

  On the other hand, even if the corresponding reel is moved (rotated) by a predetermined number of symbols, the symbol combination of the symbol combination corresponding to the winning combination lottery result cannot reach the position of the effective line. At that time, the reel is stopped so that an appropriately determined symbol is displayed at the position of the effective line. 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 state is referred to as “missing”.

  On the other hand, when the result of the lottery is lost, the reel stop control means 426 allows 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.

  Further, the reel stop control means 426 responds to the operation order of the stop switches 37L, 37C, 37R determined by the operation order determination means 424 described above when a plurality of small roles 2 or replaying roles are won in the role lottery. The reel stop control is performed so that one predetermined combination is established among the plurality of winning combinations. Here, refer to FIG. 8 for the correspondence between the symbol combination (combination) for which reel stop control is performed to be established when a plurality of winning combinations are won simultaneously in the winning combination lottery and the operation order of the stop switches 37L, 37C, 37R. Will be explained.

  FIG. 8A shows the operation sequence and the reel stop control target when a plurality of small roles 2 are simultaneously won in the role lottery (any one of the lottery result numbers “6” to “8” is derived). It is a figure which shows a response | compatibility with the kind of role which becomes. FIG. 8B shows the operation sequence and reel stop control in the case where a plurality of re-game players are won at the same time in the role lottery (any one of the lottery result numbers “12” to “14” is derived). It is a figure which shows a response | compatibility with the kind of object combination used as object. In these drawings, “first stop operation” means that, in one game, the stop switch is first operated after the reels 40L, 40C, and 40R start to rotate.

  As shown in FIG. 8A, when the lottery result number “6” is derived in the role lottery, if the first stop operation is the left stop switch 37L (that is, the operation order is left → middle → right as a result) In the case of left → right → middle), the reel stop control means 426 stops the combination of symbols corresponding to the winning combinations among the small roles 2a to 2h along the active line at the operation timing. Reel stop control is performed as displayed. On the other hand, when the first stop operation is performed on the middle stop switch 37C or the right stop switch 37R, the reel stop so that the symbol combination corresponding to the small role 2i is stopped and displayed along the active line. Take control.

  Here, the timing of the pay lines L1 to L4 shown in FIG. 1, the symbol arrangement shown in FIG. 2, and the relationship of the reel stop control means 426 control range (for 5 symbols) at any timing. Even if the stop switch is operated, any one of the symbol combinations corresponding to the small roles 2a to 2h can be stopped and displayed along the active line. On the other hand, as shown in FIG. 6, the symbol combination corresponding to the small role 2i includes the “white 7” symbol on the left reel 40L, the “BAR2” symbol on the middle reel 40C, and the “red 7” symbol on the right reel 40R. (Hereinafter, this symbol combination is written as white 7-BAR2-red 7. The same applies to other symbol combinations). Since only one of these symbols is arranged on each reel, it is necessary to operate each stop switch at a timing at which the symbol can stop at the position of the effective line. In other words, if each stop switch is not operated at a timing at which these symbols can stop at the position of the effective line, missing will occur.

  Similarly, when the lottery result number “7” is derived in the role lottery, if the first stop operation is the middle stop switch 37C (that is, as a result, the operation order is middle → left → right or middle → right → left). In this case, the reel stop control means 426 stops the reel so that the symbol combination corresponding to the winning combination that can be won among the small winning combinations 2a to 2h is stopped and displayed along the active line at the operation timing. Take control. On the other hand, when the first stop operation is performed on the left stop switch 37L or the right stop switch 37R, the reel stops so that the symbol combination corresponding to the small part 2j is stopped and displayed along the active line. Take control. Similar to the symbol combination of the small role 2i, the symbol combination corresponding to the small role 2j is also a symbol combination (red 7-BAR2-white 7) that may be missed.

  Further, when the lottery result number “8” is derived in the role lottery, if the first stop operation is the right stop switch 37R (that is, the operation order is right → left → middle or right → middle → left as a result). In this case, the reel stop control means 426 performs reel stop control so that the symbol combination corresponding to the winning combination that can be won among the small plays 2a to 2h is stopped and displayed along the active line at the operation timing. I do. On the other hand, when the first stop operation is performed on the left stop switch 37L, the reel stop control is performed so that the symbol combination corresponding to the small role 2i is stopped and displayed along the active line. If it is performed on the stop switch 37C, the reel stop control is performed so that the symbol combination corresponding to the small combination 2j is stopped and displayed along the active line.

  On the other hand, when a plurality of re-game players are won at the same time in the role lottery (any one of the lottery result numbers “12” to “14” is derived), reel stop control as shown in FIG. Is called. In other words, when the lottery result number “12” is derived in the role lottery, if the first stop operation is the left stop switch 37L, the reel stop control means 426 has the symbol combination (Plum-Plum-Plum) corresponding to the re-game player a. The reel stop control is performed so that the plum is stopped and displayed along the active line. On the other hand, when the first stop operation is performed on the middle stop switch 37C or the right stop switch 37R, the symbol combination (plum-ring-plum) corresponding to the re-game player b is along the active line. Reel stop control is performed so that the stop is displayed.

  In addition, when the lottery result number “13” is derived in the role lottery, if the first stop operation is the middle stop switch 37C, the reel stop control means 426 indicates that the symbol combination corresponding to the re-game player a is along the active line. The reel stop control is performed so that the stop display is displayed. On the other hand, when the first stop operation is performed on the left stop switch 37L or the right stop switch 37R, the reels are displayed so that the symbol combination corresponding to the re-game player b is stopped and displayed along the active line. Perform stop control.

  Further, when the lottery result number “14” is derived in the winning combination lottery, if the first stop operation is the right stop switch 37R, the reel stop control means 426 indicates that the symbol combination corresponding to the re-playing combination a is along the active line. The reel stop control is performed so that the stop display is displayed. On the other hand, when the first stop operation is performed on the left stop switch 37L or the middle stop switch 37C, the reels are displayed so that the symbol combination corresponding to the re-game player b is stopped and displayed along the active line. Perform stop control.

  Here, as shown in FIG. 2, the “plum” symbols on the left reel 40L and the right reel 40R indicate the position of the effective line (upper U or lower) by the reel stop control, no matter what timing the stop switch is operated. L) can be stopped. In addition, the “plum” symbol and the “ring” symbol on the middle reel 40C are arranged such that they can be stopped at the position of the effective line (middle stage M) by the reel stop control regardless of the operation timing of the stop switch. Therefore, when any one of the lottery result numbers “12” to “14” is derived, either the re-game player a or the re-game player b is always established. When the lottery result number “11” is derived, it means that the re-game player a is won by itself, and the reel that establishes the re-game player a regardless of the operation order of the stop switches 37L, 37C, 37R. Stop control is performed.

<Description of other means in the main control circuit>
Returning to FIG. 5, when all of the reels 40L, 40C, and 40R are controlled to be stopped by the reel control means 420, the winning determination means 430 refers to each symbol combination shown in FIG. It is determined whether or not the symbol combination corresponding to is stopped and displayed. Further, the winning determination means 430 shifts the above-described gaming state (general game, MB games 1 to 3) and RT state (non-RT, RT1, RT2) based on the winning combination as a result of winning determination. Control about. Information indicating the current gaming state and the RT state is stored in the RAM 110 shown in FIG. 3, and the information is updated each time the state changes. The winning determination means 430 is shown in a winning determination processing subroutine (see FIG. 16) described later.

  When the MB combination is established during the general game, the game state shifts to the game state of the MB game established from the general game. When the number of medals paid out during each MB game reaches a predetermined number, the MB game end condition is satisfied and the game state shifts from the MB game to the general game. The RT state shifts according to the game result during the general game. Here, transition conditions between the respective RT states will be described with reference to FIG. Immediately after the slot machine 10 is powered on and at the end of the MB games 1 to 3, the gaming state becomes a general game and the RT state becomes non-RT.

  If any of the lottery result numbers “6” to “8” is won in the role lottery when it is non-RT, but none of the small roles 2 can be won, the RT state is not set. Transition from RT to RT1. On the other hand, in the non-RT, when any of the lottery result numbers “12” to “14” is won in the combination lottery, the RT state shifts from non-RT to RT2 if the re-game combination b is established. Similarly, when the RT state is RT1, if any of the lottery result numbers “12” to “14” is won in the role lottery and the re-game combination b is established as a result of the game, the RT state Shifts from RT1 to RT2. Once the transition to RT2 is made, there is no transition to another RT state until 500 games are played in the RT state of RT2, and when 500 games are played, a transition to the non-RT RT state occurs. Transition. In any RT state, if any of MB combinations 1 to 3b is established, the game shifts to an MB game corresponding to the established MB combination.

  When the RT state is compared with non-RT and RT1, the winning probability of each MB combination and small combination in the combination lottery is the same as non-RT in the combination lottery, but the winning probability of the re-game combination is increased. Therefore, it is possible to play a large number of games with a small number of medals compared to non-RT, and the number of opportunity lottery increases accordingly, which can be said to be advantageous to the player. Further, comparing non-RT and RT2, if non-RT, if small role 2 is missed, it can move to RT1, but RT2 cannot move to RT1 unless it passes through non-RT. In addition, it is not possible to shift to non-RT unless 500 games are played. For this reason, it can be said that RT2 is in a disadvantageous state for the advantager compared with non-RT.

  The role lottery probability changing means 440 refers to the RT state information stored in the RAM 110 and selects a role lottery table corresponding to the current RT state from the role lottery tables shown in FIG. This combination lottery probability changing means 440 is shown in step S42 of the combination lottery processing subroutine shown in FIG. When it is determined by the winning determination means 430 that any small combination has been established, the winning processing means 450 drives a hopper (not shown) provided in the slot machine 10 to change the established small combination to the winning combination. Control for paying out the corresponding number of medals is performed. This winning processing means 450 is shown in step S38 of a main routine (see FIG. 13) described later.

≪Description of sub control circuit≫
The sub control circuit 200 mainly includes an effect control unit 510 and a notification control unit 520. The effect control unit 510 includes an effect data storage unit 512 and an effect lottery unit 514, and determines the contents of the effect executed by the notification unit 600 based on various control information transmitted from the main control circuit 100. The effect data storage means 512 stores various data such as image (moving image or still image) data to be displayed on the image display device 70, sound effects or musical sound data emitted from the speakers 64L and 64R, and data indicating a blinking pattern of the upper effect lamp 72. I remember it. When the effect lottery means 514 receives information on the result of the role lottery from the main control circuit 100, the effect lottery means 514 selects various data according to the result of the role lottery from the effect data storage means 512 based on the random number lottery. Then, the effect control means 510 causes the effect means 600 to execute effects based on various data selected by the effect lottery means 514. As an effect to be executed by the effect means 600, for example, an action that suggests to the player the type of the winning combination by the role lottery means 410 is conceivable.

  The notification control unit 520 includes an end lottery unit 521, a winning probability setting unit 522, an end condition selecting unit 523, an end condition storage unit 524, a winning number counting unit 525, a game medium calculating unit 526, and a winning probability varying unit 527. is doing. Then, during the general game, the control related to the special general game in which a notification that is a game result advantageous to the player is performed is performed. Here, in the special general game, the following content is notified as a notification that is a game result advantageous to the player.

(1) When the RT state is RT1, if any of the lottery result numbers “6” to “8” is derived in the role lottery, any of the small roles 2a to 2h will win a stop switch The operation order of 37L, 37C, and 37R (see FIG. 8A) is notified before the first stop operation is performed.
(2) When the RT state is non-RT or RT1, the stop switch 37L in which the re-game combination a is established when any of the lottery result numbers “12” to “14” is won in the combination lottery. The operation order of 37C and 37R (see FIG. 8B) is notified before the first stop operation is performed.

  In the notification of (1) described above, when the player operates the stop switches 37L, 37C, and 37R in the notified operation order, any of the small roles 2a to 2h wins and is not missed. It can be said that the notification is a game result advantageous to the player. In the notification (2), when the player operates the stop switches 37L, 37C, and 37R in the operation order notified, the re-game player b is not established and the re-game player a is established. Therefore, since it is possible to avoid the transition to RT2, which is in a disadvantageous state for the player (see FIG. 9), it can be said that the notification results in a game result that is advantageous to the player. As a specific notification mode, for example, an image corresponding to the type (one of right, middle, and left) of the stop switch that should perform the first stop operation is displayed on the image display device 70. It is possible to output from 64L and 64R, or to blink the upper effect lamp 72 by a corresponding blinking pattern.

  The period during which the special general game described above is performed is called assist replay time (ART). The transition to ART is when one of the MB roles 1, 2, 3a and 3b is won in the role lottery, or when the transfer lottery executed when the small role 4 wins as a result of the game is won. Done. In addition, when the number of winning lotteries, which will be described later, is reached a predetermined number, the ART ends. In the slot machine 10, various conditions related to the end lottery are changed to affect the sustainability of the ART, thereby improving the fun related to the game.

  In FIG. 5, the end lottery means 521 derives the lottery result number “11” as a result of the role lottery by the role lottery means 410 during the ART (the re-game player a is won alone, see FIG. 7). An end lottery is performed based on the winning probability set by the winning probability setting means 522, and it is determined whether or not the end lottery is won. The control processing by the end lottery means 521 is shown in steps S232 and S234 of an ART notification control subroutine (see FIG. 18) described later. The winning probability setting means 522 selects any one of six predetermined winning probabilities for the lottery by a random number lottery (hereinafter referred to as a selected lottery) based on a selection probability described later. Then, the selected winning probability is set as the winning probability used for the end lottery. The control processing by the winning probability setting means 522 is shown in steps S314, S340, and S330 of an effect image control subroutine (see FIG. 20) described later.

  As shown in FIG. 10, the winning probability of the end lottery is set to six types of 1/1, 1/15, 1/23, 1/53, 1/107, 1/213. As shown in FIG. 10, there are five selection probabilities A to E as selection probabilities A to E, and one of the selection probabilities B to E is specified according to the end condition. The state in which the winning probability is selected according to the selection probability A will be described later. When selecting a winning probability based on the selection probability A, a winning probability of 1/1 is always selected. When selecting a winning probability based on the selection probability B, a winning probability of 1/15 is selected with a probability of 92%, a winning probability of 1/23 is selected with a probability of 5%, and a probability of 1% each. Then, one of 1/53, 1/107, and 1/213 is selected.

  When selecting the winning probability based on the selection probability C, a winning probability of 1/15 is selected with a probability of 40%, a winning probability of 1/23 is selected with a probability of 50%, and 1 with a probability of 6%. A winning probability of / 53 is selected, a winning probability of 1/107 is selected with a probability of 3%, and a winning probability of 1/213 is selected with a probability of 1%. Further, when selecting a winning probability based on the selection probability D, a winning probability of 1/23 is selected with a probability of 40%, a winning probability of 1/53 is selected with a probability of 50%, and a probability of 6% The winning probability of 1/107 is selected with, and the winning probability of 1/213 is selected with a probability of 4%. Further, when the winning probability is selected based on the selection probability E, the winning probabilities of 1/107 and 1/213 are selected with a probability of 50% each.

  The end condition selection means 523 determines whether or not to shift to ART based on the lottery table shown in FIG. 11 when any of the MB roles 1 to 3b is won in the role lottery or when the small role 4 wins. (Hereinafter referred to as “transfer lottery”). As shown in the lottery table of FIG. 11, the probability of shifting to ART differs depending on the type of winning combination in the winning lottery or as a result of the game and the gaming state at that time. In other words, when MB combination 1 is selected among MB combinations 1 to 3b in the combination lottery, it always shifts to ART, but when MB combination 2 wins, it shifts to ART with a probability of 50%. It will be. Also, when MB combination 3a or 3b is won, if the game state at that time is a general game, it moves to ART with a probability of 30%, and if it is won during ART, it moves to ART with a probability of 20%. Will do. In addition, the processing when winning a lottery for shifting to ART during ART will be described in detail later. On the other hand, when the small combination 4 wins, it always shifts to ART regardless of the gaming state.

  When it is determined to shift to ART in the above-described transfer lottery, the end condition selection unit 523 selects any one of a plurality of types of end conditions stored in the end condition storage unit 524. This end condition storage means 524 corresponds to the RAM 210 shown in FIG. Here, the contents of the end condition will be described with reference to FIG. The termination condition includes the number of winning lotteries at which the ART will be terminated, and information indicating the selection probabilities referenced when setting the winning probabilities before winning the final lottery. FIG. An end condition group including end conditions 1 to 14 is shown. In addition, a maximum of three selection probabilities are defined for each termination condition, and the number of selection probabilities indicates the number of winnings. In addition, the alphabets “B” to “E” described in the “1” column, “2” column, and “3” column of the “end condition” column are the selection probabilities B to E shown in FIG. It corresponds. Here, below, the selection probability described in the “1” column is the first selection probability, the selection probability described in the “2” column is the second selection probability, and the selection probability described in the “3” column. Is called the third selection probability.

  When the ART is started based on the above-described end condition, first, the winning probability of the end lottery is selected based on the first selection probability among the selection probabilities described in the winning probability selection table shown in FIG. . Thereafter, each time the end lottery is won, the winning probability is selected based on the second and third selection probabilities sequentially. If the winning lottery is selected after selecting the winning probability based on the final selection probability, No. 1 to No. In any of the 14 end conditions, the winning probability is always selected based on the selection probability A. As shown in FIG. 10, when the selection of the winning probability based on the selection probability A, the winning probability of 1/1 is selected with a probability of 100%. Then, the end lottery is performed with a winning probability of 1/1, and when the winning lottery is made in the end lottery, the ART ends.

  For example, as shown in FIG. When the ART is started based on the end condition of 1, the winning probability of the end lottery is first selected based on the first selection probability (selection probability B) at the start. Thereafter, when the end lottery is performed, the end lottery is performed according to the winning probability selected at the start of the ART. Then, when winning in the end lottery, the winning probability is selected based on the selection probability A, and when the end lottery is won in this state, the ART ends.

  For example, the end condition No. When 12 is selected, the winning probability setting means 522 selects the winning probability based on the first selection probability (selection probability D) at the start of the ART, and when the winning lottery is first won in this state, A winning probability is selected based on the second selection probability (selection probability C). If the winning lottery is further won, the winning probability is selected based on the third selection probability (selection probability B). When the last lottery is won in this state, the winning probability setting means 522 selects the winning probability based on the selection probability A. As a result, the winning probability of the end lottery becomes 100%. When the lottery result number “11” is derived in the role lottery in this state, the end lottery is always won. And by this winning, the notification control means 520 ends ART.

  The end condition group (see FIG. 12) stored in the end condition storage means 524 is No. It consists of 1 to 14 end conditions, and each end condition has a selection rate according to various game states. Then, when the transition to ART is determined as a result of the transition lottery based on the lottery table shown in FIG. 11, the termination condition selection means 523 determines the termination condition according to the selection rate corresponding to the gaming state at that time. select. In FIG. 12, the selection rate shown in the “in general game” column is a selection rate that is referred to when winning one of the MB roles 1 to 3 b in the role lottery or winning the small role 4 during the general game. Is shown. The selection rate shown in the "A during ART" column indicates a selection rate that is referred to when winning a small role 4 during ART. The selection rate shown in the “ART B” column indicates the selection rate that is referred to when one of the MB roles 1 to 3b is won in the role lottery during ART. The selection rate shown in the “MB game” column indicates the selection rate that is referred to when winning a small role 4 when any of the MB games 1 to 3 is performed.

  Of the selection rates shown in FIG. 1-No. No end condition 6 is selected. This indicates that there is a high possibility that an end condition of 7, 10, or 12 is selected. No. Like the end conditions of 9, 11, 13, and 14, when setting the winning probability in the end lottery, the end condition including the selection probability E (see FIG. 10) that selects a low winning probability is also a low probability ( 1%).

  In addition, the selection rates shown in the “first ceiling” column and the “second ceiling” column are referred to when the end condition is selected without performing the transition lottery when each of the predetermined conditions is satisfied. It is what is done. The selection rate shown in the “first ceiling” column is referred to when the game is played 500 times without the MB game being played with the RT state being RT2. That is, after 500 games are played after the transition from non-RT or RT1 to RT2, the transition to non-RT is made (see FIG. 9). At this time, the end condition is selected based on the selection rate shown in the “first ceiling” column without performing the transfer lottery, and the process proceeds to ART.

  The selection rate shown in the “second ceiling” column is referred to when the number of times of not winning the transfer lottery based on the transfer lottery table shown in FIG. 11 becomes 7 consecutive times. As a result, if the transition lottery is not won seven times in succession, the end condition is selected based on the selection rate shown in the “second ceiling” column, and the process proceeds to ART. The above-described control process by the end condition selection means 523 is shown in an end condition selection lottery process subroutine (see FIG. 19) described later.

  Returning to FIG. 5, the winning number counting means 525 counts the number of times the end lottery 521 has won the end lottery. The control processing by the winning number counting means 525 is shown in steps S326 and S328 of an effect image control subroutine (see FIG. 20) described later. The game medium calculation means 526 stores the number of medals inserted into the slot machine 10 and the number of medals paid out for each game from the present to the past 17500 times. Then, the total value of the number of inserted medals and the total number of paid-out medals are calculated for each of the past 400 times, 6000 times, and 17500 times from the present. The control processing by the game medium calculating means 526 includes step S202 of an ART notification control subroutine (see FIG. 18) described later, step S292 of an effect image control subroutine (see FIG. 20), and a winning probability adjustment processing subroutine (see FIG. 22). ) In steps S380, S386, and S390.

  The winning probability varying means 527 is a predetermined number of games (400, 6000, 17500) from the present time calculated by the game medium calculating means 526 when the winning probability of the end lottery is set by the winning probability setting means 522. A value obtained by dividing the total value of the number of medals paid out in the past by the total value of the number of inserted medals is calculated. When this value exceeds a predetermined value, the winning probability set by the winning probability setting means 522 is increased. The control processing by the winning probability changing means 527 is shown in steps S382, S384, S388, and S392 of a winning probability adjustment processing subroutine (see FIG. 22) described later.

  The notification control means 520 having the above various means, during ART, the number of winning the end lottery instructed by the end condition selected by the end condition selecting means 523, the number of winning the end lottery so far, The selection probability used when the winning probability setting means 522 sets the winning probability of the end lottery during the displayed ART is displayed on the image display device 70.

[Description of control processing]
Next, various controls performed in the control circuit described above will be described in detail with reference to flowcharts.

Of these subroutines, FIG. 14 is a flowchart of the role lottery processing subroutine for performing the role lottery by the role lottery means 410 shown in FIG. 5 and the role lottery table switching control by the role lottery probability varying means 440. FIG. 15 is a flowchart of a reel fluctuation / stop subroutine in which the reel control means 420 controls the reels 40L, 40C, 40R to rotate and stop. FIG. 16 is a flowchart of a prize determination processing subroutine that is performed by the winning determination means 430 to determine the presence / absence of the established combination and the type of the established combination and to give the player a privilege corresponding to the established combination. . FIG. 17 is a flowchart of the winning combination processing subroutine that forms part of the winning determination processing subroutine of FIG. 18 to 22 are flowcharts illustrating various control processes related to ART based on the control information received from the main control circuit 100 in the sub control circuit 200. FIG.

[Description of control processing in main control circuit]
≪Description of main routine≫
First, a description will be given of the control process 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 S146 of the winning combination processing subroutine shown in FIG. 17 described later when a re-game combination 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 24a, 24b, 24c shown in FIG. The lighting state of is updated (step S20). Next, the CPU 106 determines whether or not the value of the number of bets stored in the RAM 110 has reached a specified number (three) (step S22). If it is determined 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 S28).

  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 (step S24). 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 that the re-game establishment flag is on (YES), the CPU 106 turns off the re-game establishment flag (step S13), and then proceeds to step S28 to play the game. It is determined whether or not 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 S28, the CPU 106 determines whether or not a reel rotation start signal has been received from the start switch 36 (step S28). Since the reel rotation start signal is not received, if it is determined that the start switch 36 is not operated by the player (NO), the determination in step S28 is performed again. Until the reel rotation start signal is received, the CPU 106 repeats the process of step S28. 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 it is determined in step S28 that the player has operated the start switch 36 (YES) because the CPU 106 has received the reel rotation start signal, the combination lottery processing subroutine shown in FIG. 14 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 variation / 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 and 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. A winning determination process subroutine for performing the transfer process is executed (step S34). 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 S30, the CPU 106 performs a payout process (step S38) for paying out the number of medals corresponding to the small winning combination. In the payout process, it is possible to actually pay out medals from the medal payout outlet 60, or credit the medals by adding the number of medals to be paid out to the credit number stored in the RAM 110. 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 game state stored in the RAM 110 and determines whether or not the current game state is a general game (step S40). When it is determined that the current game state is a general game (YES), the current lot state table corresponding to the current RT state is read with reference to the current RT state stored in the RAM 110 (step S42). That is, if the current RT state is non-RT or RT2, the role lottery table shown in FIG. 7A (as described above, strictly separate lottery tables with slightly different winning probabilities for re-game players) If it is RT1, the combination lottery table shown in FIG. 7B is read.

  Next, the CPU 106 acquires the random number generated by the random number generator 112, and determines whether any winning combination has been won or lost in comparison with the winning lottery table read in step S42 (step S44). That is, the acquired random number is sequentially compared with the winning numerical range corresponding to each lottery result number in the winning lottery table, and the lottery result number corresponding to the winning numerical range including the acquired random number is derived as the result of the winning lottery. Is done. The processing in step S44 corresponds to the random number extraction means 412 and the random number determination means 414 shown in FIG. In addition, by the process of step S42, the winning lottery is performed based on the winning lottery table read from the ROM 108 according to the current RT state, and the winning probability of the re-gamer in the winning lottery varies according to each RT state. Therefore, it can be said that the process of step S42 corresponds to the role lottery probability changing means 440 shown in FIG.

  The CPU 106 regards the winning combination corresponding to the derived lottery result number as the winning combination in the winning lottery (hereinafter simply referred to as winning winning combination), and winning corresponding to each winning combination (see FIG. 6) preset in the RAM 110. Of the flags, the winning flag corresponding to the winning combination is turned on (step S46). Here, in the combination lottery table, when lottery result numbers (“6” to “8”, “12” to “14”) associated with a plurality of combinations are derived, all corresponding to the plurality of combinations Turn on the winning flag. As will be described in detail later, the ON / OFF state of each winning flag is referred to when the reel stop control is performed by the reel fluctuation and stop subroutine processing shown in FIG.

  Next, the CPU 106 determines whether or not the small combination 2 has been won simultaneously (step S48). If it is determined that a plurality of small roles 2 are simultaneously won (YES), the reel stop control information corresponding to the lottery result number (any one of “6” to “8”) (see FIG. 8A). Are read from the ROM 108 and stored in the RAM 110 (step S50). On the other hand, if it is determined in step S48 that the plurality of small combinations 2 have not been won simultaneously (NO), the CPU 106 determines whether or not a plurality of replaying combinations have been won simultaneously (step S52). . If it is determined that a plurality of re-game players have been won simultaneously (YES), the reel stop control information corresponding to the lottery result number (any one of “12” to “14”) (see FIG. 8B) Is read from the ROM 108 and stored in the RAM 110 (step S54).

  When the CPU 106 finishes the process of step S50 or S54, or determines that it has not won a plurality of small combinations 2 or re-playing combinations at the same time (step S52, NO), it immediately determines the derived lottery result number. The control target symbol data is read from the ROM 108 and stored in a predetermined storage area of the RAM 110 (step S56). The control target symbol data is data indicating a symbol to be stopped and displayed at the position of the effective line when the reel stop control is performed in the reel fluctuation / stop subroutine process described below. In other words, the control target symbol data can be said to be data indicating the contents of the symbol symbol combination (see FIG. 6) corresponding to the derived lottery result number.

  Then, the CPU 106 obtains the role lottery information including at least the current game state and RT state, the number of inserted medals ("0" when replaying), and the derived lottery result number. (Step S58). Then, the combination lottery process subroutine is terminated, and the process proceeds to step S32 of the main routine shown in FIG.

  In the determination process of step S40, if it is determined that the current game state is not a general game, that is, one of the MB games 1 to 3 (NO), among the winning flags in the RAM 110, The winning flags corresponding to all small combinations including 5 are turned on (step S60). Thereafter, the process proceeds to step S58, where the role lottery information is transmitted to the sub-control circuit 200, and the role lottery processing subroutine ends.

<Explanation of reel fluctuation / stop subroutine>
In the main routine shown in FIG. 13, when the above-described combination lottery process subroutine (step S30) is completed, the CPU 106 next performs a reel fluctuation and stop subroutine (step S32). A detailed description will be given below with reference to the flowchart of the reel fluctuation / stop subroutine shown in FIG.

  First, the CPU 106 reads out the lottery result number and control target symbol data stored in step S56 of FIG. 14 from the RAM 110 (step S70). 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 S72). If it is determined that the shortest time has not elapsed (NO), the determination process in step S72 is repeatedly executed. That is, the rotation of the reel, which is the next process, is not performed until the shortest time has elapsed. Thus, control is performed so that the number of medals consumed by a game played within a predetermined time does not exceed a predetermined number. When determining that the shortest time has passed (YES), the CPU 106 transmits a reel rotation start signal to the motor drive circuit 114 shown in FIG. 3 (step S74). Based on this signal, the motor drive circuit 114 starts driving the motors 80L, 80C, 80R, and the reels 40L, 40C, 40R start rotating.

  Next, the CPU 106 determines whether or not the reel that has started rotating is at a constant speed (step S76). If it is determined that the rotation of the reel has not yet reached a constant speed (NO), the determination process in step S76 is repeated. That is, the reel stop control, which is the next step, is not performed until the rotation of the reel reaches a constant speed. If the CPU 106 determines that the rotation of the reel is a constant speed rotation (YES), it is next determined whether or not a reel stop signal has been received from the stop switches 37L, 37C, 37R (step S78). . This reel stop signal is transmitted from each of the stop switches 37L, 37C, and 37R when the player performs a push operation. Further, the CPU 106 performs reel stop control corresponding to the stop switch that has transmitted the reel stop signal. That is, when a reel stop signal is transmitted from the left stop switch 37L, stop control of the motor 80L that rotates the left reel 40L is performed. Similarly, when the reel stop signal is transmitted from the middle stop switch 37C, the stop control of the motor 80C for rotating the middle reel 40C is performed, and when the reel stop signal is transmitted from the right stop switch 37R, Stop control of the motor 80R that rotates the right reel 40R is performed.

  If the CPU 106 determines 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 to the sub-control circuit 200 (step S80). Next, the CPU 106 performs symbol combination control based on various information read from the RAM 110 in step S70 (step S82). In the symbol combination control, the stop position can be shifted from the symbol position displayed on the display window 22 when the reel stop signal is received until the reel is rotated by a maximum of four symbols. Then, the winning flag of each winning combination stored in the RAM 110 is checked, and the reels are stopped so that the symbol combination corresponding to the winning flag being turned on is stopped and displayed along one effective line. Take control.

  Here, when the current gaming state is one of the MB games 1 to 3, the CPU 106 performs the reel stop control within the range of 4 symbols for the middle reel 40C and the right reel 40R. For the reel 40L, the reel stop position is performed within a maximum of two symbols. Further, in the general game, when any of the lottery result numbers “6” to “8” and “12” to “14” is derived in the role lottery, as shown in FIG. The combination to be established differs depending on the operation order of 37C and 37R. That is, in order to stop display along the active line, the symbol combinations that are subject to reel stop control differ depending on the operation order.

  Next, the CPU 106 determines whether or not all reels have been stopped (step S84). If it is determined that all the reels are not stopped (NO), the process returns to step S78, and the symbol combination control according to the reel stop signal is performed again. If it is determined in step S78 that a reel stop signal has not been received (NO), the process proceeds directly to step S84 to determine whether all reels have been stopped. As described above, the processes in steps S78 to S84 are repeated until all the reels are stopped. When the CPU 106 determines that all the reels are stopped (YES) in step S84, the reel fluctuation and stop process is ended. 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. 13, 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 identifies the types of nine symbols that are stopped and displayed on the display window 22, and recognizes the symbol combinations that are stopped and displayed along each of the effective lines L1 to L4 (step S90). 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 an MB game (step S91). If it is determined that the MB game is being played (YES), the CPU 106 determines whether there is a symbol combination corresponding to any small role among the symbol combinations stopped and displayed along each of the active lines L1 to L4. (Step S94). If it is determined that there is a symbol combination corresponding to some small combination (YES), the CPU 106 prepares for paying out medals, assuming that the small combination has won.

  That is, the payout number of medals corresponding to the winning small combination is read out from the payout information shown in FIG. 6, and the payout number count value stored in the RAM 110 is updated to the read out payout value (step S96). . As a result, in step S38 in the main routine shown in FIG. 13, the updated payout number count value is read, and the hopper in the slot machine 10 is driven until the same number of medals are paid out. Next, the CPU 106 adds the value of the number of payouts of medals corresponding to the winning small combination to the value of the total number of payouts stored in the RAM 110 (step S98). Then, based on the value of the total number of payouts updated by the process of step S98, it is determined whether or not the termination condition for the currently performed MB game is satisfied (steps S100 to S108).

  First, the CPU 106 proceeds to step S100 and determines whether or not the current MB game is MB game 1. When the current MB game is MB game 1 (YES), it is determined whether or not the value of the total number of payouts exceeds 280 (step S102). If the total payout count value exceeds 280 (YES), it is determined that the end condition of MB game 1 is satisfied, and if it does not exceed, it is determined that the end condition is not satisfied (NO). If it is determined in step S100 that the current MB game is not MB game 1 (NO), then the CPU 106 determines whether or not the current MB game is MB game 2 (step S104). ). If the current MB game is MB game 2 (YES), it is determined whether or not the total payout count value exceeds 140 (step S106). If the total payout count value exceeds 140 (YES), it is determined that the end condition of MB game 2 is satisfied, and if it does not exceed, the end condition is determined not satisfied (NO). Further, in the determination process of step S104, if it is determined that the current MB game is not MB game 2 (NO), the CPU 106 regards the current MB game as MB game 3, and the value of the total number of payouts is 40. It is determined whether or not it exceeds (step S108). If the total payout count value exceeds 40 (YES), it is determined that the end condition of the MB game 3 is satisfied, and if it does not exceed, it is determined that the end condition is not satisfied (NO).

  When the CPU 106 determines that the current MB game end condition has been satisfied (steps S102, S106, S108 → YES) by performing the above steps S100 to S108, the current stored in the RAM 110 is stored. The game state is updated to “general game” (step S110). Further, the current RT state stored in the RAM 110 is updated to “non-RT” (step S112). Then, all winning flags of each combination stored in the RAM 110 are turned off (step S114), and game result information including information on the presence / absence of the established combination, the type of established combination and the number of medals to be paid out is obtained. It transmits to the control circuit 200 (step S116). Then, the winning determination process subroutine is terminated, and the payout process of step S38 in the main routine of FIG. 13 is performed.

  On the other hand, if the CPU 106 determines that the current MB game end condition is not satisfied (steps S102, S106, S108 → NO), the process proceeds to step S114 without performing the processes of steps S110 and S112. Turn off all winning flags for each role. Then, the process proceeds to step S116, and the above-described game result information is transmitted to the sub-control circuit 200. Further, during the MB game (step S92, YES), if the small role is not won (step S94, NO), the CPU 106 sets the value of the number of payouts stored in the RAM 110 to “0” (step S94). S118). Then, the process proceeds to step S116, and after the game result information is transmitted to the sub-control circuit 200, the winning determination process subroutine is terminated, and the payout process of step S38 in the main routine of FIG. 13 is performed.

  If it is determined in step S92 that the current gaming state is not in MB gaming (NO), the CPU 106 considers the current gaming state to be a general game, and displays the winning flag for each combination stored in the RAM 110. It is referred and it is determined whether there is a winning combination (step S120). If there is a winning combination (YES), the CPU 106 executes a winning combination processing subroutine described next with reference to FIG. 17 (step S122). Then, when the process of the winning combination process subroutine is completed, the process proceeds to step S116, and game result information is transmitted to the sub-control circuit 200. In contrast, if it is determined in step S120 that there is no winning combination, the process immediately proceeds to step S116, and game result information is transmitted to the sub-control circuit 200. Then, the winning determination process subroutine is terminated, and the payout process of step S38 in the main routine of FIG. 13 is performed.

<Description of the processing subroutine at the time of winning the role>
Next, the contents of the winning combination processing subroutine executed in step S122 of the winning determination processing subroutine shown in FIG. 16 will be described using the flowchart shown in FIG. First, the CPU 106 refers to the payout information shown in FIG. 6 stored in the ROM 108, and among the symbol combinations that are stopped and displayed along each active line, the symbol combination of MB combination 1 (red 7-red 7). -It is determined whether there is red 7) (step S130). When there is a symbol combination of MB combination 1 (YES), the current gaming state stored in the RAM 110 is updated to “MB gaming 1” (step S132).

  In step S130, if the CPU 106 determines that there is no MB combination 1 symbol combination (NO), the MB combination 2 symbol combination (white 7- It is determined whether there is white 7-white 7) (step S134). When there is a symbol combination of MB combination 2 (YES), the current gaming state stored in the RAM 110 is updated to “MB gaming 2” (step S136). In step S134, when the CPU 106 determines that there is no symbol combination of MB combination 2 (NO), the combination of MB combination 3a or MB combination 3b is displayed in the combination of symbols stopped and displayed along each active line. It is determined whether there is a symbol combination (red 7-red 7-white 7 or white 7-white 7-red 7) (step S138). When there is a symbol combination of the MB combination 3a or the MB combination 3b (YES), the current gaming state stored in the RAM 110 is updated to “MB gaming 3” (step S140).

  When the current game state is updated to the MB game corresponding to each established MB combination by the processes of steps S132, S136, and S140, the CPU 106 sets the payout number count and the total number of payout counts stored in the RAM 110 as the values. Both are set to “0” (step S142). Then, all winning flags stored in the RAM 110 are turned off (step S144), and the winning combination processing subroutine shown in FIG. 17 is ended.

  When a combination other than the various MB combinations has been won (step S138, NO), the CPU 106 displays a combination of symbols of the replaying combination a or the replaying combination b in the combination of symbols stopped and displayed along each active line. It is determined whether or not there is (Plum-Plum-Plum or Plum-Ring-Plum) (Step S146). When there is a symbol combination of the re-gamer a or the re-gamer b (YES), the CPU 106 turns on the re-gamer establishment flag stored in the RAM 110 (step S148). Then, the payout number count value stored in the RAM 110 is set to “0” (step S150), and the current RT state is read from the RAM 110 (step S152).

  In step S146, when the CPU 106 determines that there is no symbol combination of the re-gamer a or the re-gamer b (NO), there is a symbol combination corresponding to one of the small roles 1 to 5 next. Whether or not (step S154). When the CPU 106 determines that there is no symbol combination corresponding to any of the small roles 1 to 5 (NO), the process proceeds to step S150, and the payout number count value stored in the RAM 110 is set. Set to “0”. In this case, the winning combination is present (step S118 in FIG. 16, YES), the re-playing role a or the re-playing role b that cannot be lost has not been established (step S146, NO), and any small Since no role has been won, any small role or MB role has been missed.

  On the other hand, if there is a symbol combination corresponding to any of the small combinations 1 to 5 in step S154 (YES), the medal corresponding to the winning small combination is determined from the payout information shown in FIG. The payout number is read out and the payout number count value stored in the RAM 110 is updated to the read out payout value (step S156). Then, when the process of step S150 or S156 is completed, the CPU 106 proceeds to step S152 and reads the current RT state from the RAM 110.

  Next, the CPU 106 performs transition control of the RT state by the processing of steps S158 to S176. First, the CPU 106 determines whether or not the current RT state is “non-RT” (step S158). When it is “non-RT” (YES), the CPU 106 wins any of the small roles 2a to 2j even though any of the lottery result numbers “6” to “8” is derived in the role lottery. It is determined whether or not it has been done (step S160). When none of the small roles 2 has won (YES), the CPU 106 sets the current RT state stored in the RAM 110 to “RT1” (step S162).

  On the other hand, if none of the lottery result numbers “6” to “8” is derived in the role lottery, or if it is derived but any of the small roles 2a to 2j wins, the determination in step S160 The result is NO. In this case, the CPU 106 determines whether or not the re-game player b is established (step S164). Then, when the re-game player b is established (YES), the CPU 106 updates the current RT state from “non-RT” to “RT2” (step S166). On the other hand, when the re-game player b is not established (NO), “non-RT” is maintained as the current RT state.

  If the CPU 106 determines in step S158 that the current RT state is not “non-RT” (NO), it next determines whether or not the current RT state is “RT1” (step S). When the current RT state is “RT1” (YES), the CPU 106 proceeds to step S164 and determines whether or not the re-game player b is established. If the re-game player b is established (YES), the CPU 106 proceeds to step S166 and updates the current RT state from “RT1” to “RT2”. On the other hand, when the re-game player b is not established (NO), “RT1” is maintained as the current RT state.

  If CPU 106 determines in step S168 that the current RT state is not “RT2” (NO), it regards the current RT state as “RT2” and adds “1” to the value of variable RT (step S170). The variable RT is a variable for counting the number of games played when the RT state is “RT2”, and the value is stored in the RAM 110. Then, CPU 106 determines whether or not the value of variable RT has exceeded 500 (step S172). When the value of variable RT exceeds 500 (YES), CPU 106 updates the current RT state from “RT2” to “non-RT” (step S174), and sets the value of variable RT to “0” (step S174). Step S176). If the value of variable RT does not exceed 500 (step S172, NO), CPU 106 maintains the current RT state as “RT2”.

  When the transition control of the RT state is performed by the processing of steps S158 to S176, the CPU 106 turns off the winning flag of the small combination or replaying combination that is turned on among the winning flags of each combination stored in the RAM 110. (Step S178). Here, when the winning flag of any of MB combinations 1 to 3b is turned on, the CPU 106 maintains the state of the winning flag of the MB combination being on. That is, the winning flag for the small combination and the re-playing combination is turned off when one game is completed, but the winning flag for the MB combination is kept on until the MB combination is established. Thus, the state when the ON state of the winning flag corresponding to the MB winning combination in the winning lottery is maintained is referred to as the bonus flag being carried over.

  As described above, in the symbol combination control performed in step S82 of the reel fluctuation / stop subroutine shown in FIG. 15, the symbol combination corresponding to the combination for which the winning flag is turned on is the target of the reel stop control. It has become. Therefore, while the bonus flag is being carried over, the player can establish an MB combination corresponding to the winning flag being carried over.

  When the processing of step S178 is completed, the CPU 106 ends the winning combination processing subroutine of FIG. 17, and performs the processing of step S116 of the winning determination processing subroutine shown in FIG.

  By performing the above processing, the main control circuit 100 controls the game as a slot machine. In addition, the main control circuit 100, in one game, in the order of combination lottery information (FIG. 14, step S60), stop operation information (FIG. 15, step S80), game result information (FIG. 16, step S116). Then, each information is transmitted to the sub control circuit 200.

[Description of control processing in sub-control circuit]
Next, the control related to the ART performed by the CPU 206 (see FIG. 4) of the sub-control circuit 200 and the contents of the effect control performed during the ART will be described with reference to the flowcharts shown in FIGS. FIG. 18 is a flowchart of an ART notification control subroutine for performing notification that gives a game result advantageous to the player during ART. FIG. 19 is a flowchart of an end condition selection lottery process subroutine for selecting an ART end condition. FIG. 20 is a flowchart of an effect image control subroutine for controlling an image effect executed during ART. FIG. 21 is a flowchart of an ART effect interruption process subroutine for interrupting an image effect during ART when the game shifts to any of MB games 1 to 3 during ART. FIG. 22 is a flowchart of a winning probability adjustment processing subroutine for adjusting the winning probability of the end lottery, which is the establishment factor of the ART end condition.

<Description of ART notification control subroutine>
In FIG. 18, first, the CPU 206 determines whether or not role lottery information has been received from the main control circuit 100 (step S200). If it is determined that the role lottery information has not been received (NO), the CPU 206 ends the ART notification control subroutine and performs other processing. On the other hand, if it is determined that the winning lottery information has been received (YES), it is stored in the RAM 210 based on the information on the number of medals inserted in the current game included in the received winning lottery information. The inserted number history is updated (step S202). The inserted number history records the number of medals inserted into the slot machine 10 in each game from the current game to the past 17500 times. The update of the input number history is performed by deleting the oldest input number record and newly recording the latest input number.

  Next, the CPU 206 determines whether or not the current gaming state is a general game based on the information indicating the current gaming state included in the received combination lottery information (step S204). When the CPU 206 determines that the current gaming state is a general game (YES), the CPU 206 determines the MB roles 1 to 3b in the role lottery based on the lottery result number information included in the received role lottery information. It is determined whether or not any of the above has been won (step S206). If it is determined that one of the MB roles 1 to 3b has been won (YES), the CPU 206 performs an end condition selection lottery process shown in FIG. 19 assuming that the ART start condition is satisfied (step S208). When the end condition selection lottery process ends, the CPU 206 determines whether or not the current RT state is “RT2” based on information indicating the current RT state included in the received combination lottery information. (Step S210).

  When it is determined that the current RT state is “RT2” (YES), the CPU 206 adds “1” to the value of the variable RT2 stored in the RAM 110 (step S212) and is not “RT2” (NO ), The value of the variable RT2 is set to “0” (step S214). This variable RT 2 is a variable for counting the number of games played when the RT state is “RT 2”, and the value is stored in the RAM 210.

  When the interruption flag is turned on in step S208 or the value of the variable RT2 is updated in step S212 or S214, the CPU 206 determines whether or not the state of the ART flag stored in the RAM 210 is on. (Step S216). When determining that the ART flag has been turned off (NO), the CPU 206 ends the ART notification control subroutine and performs other processing. On the other hand, when determining that the ART flag has been turned on (YES), the CPU 206 next determines whether or not the state of the interruption flag stored in the RAM 210 is turned off (step S218). This interruption flag is a flag that is turned on when any of the MB games 1 to 3 is transferred during ART, and is turned off when the MB game is ended, and the ART continues. This on / off control of the interruption flag is performed by an ART effect interruption process described later. When determining that the interruption flag is on (NO), the CPU 206 ends the ART notification control subroutine and performs other processing. On the other hand, if it is determined that the interruption flag has been turned off (YES), the CPU 206 performs a process for notifying the player of a game result advantageous to the player.

  That is, first, the CPU 206 selects one of the lottery result numbers “12” to “14” (simultaneous winning of a plurality of re-game players) based on the lottery result number information included in the received lottery information. It is determined whether or not has been derived (step S220). If it is determined that one of the lottery result numbers “12” to “14” has been derived (YES), the CPU 206 next determines whether the current RT state is “RT2” based on the received combination lottery information. It is determined whether or not (step S222). When it is determined that the current RT state is not “RT2”, that is, “non-RT” or “RT1” (NO), the re-game player a is established in the derived lottery result number. A stop switch for one stop operation is notified (step S224).

  That is, as shown in FIG. 8B, when the lottery result number “12” is derived, it is notified that the first stop operation of the left stop switch 37L should be performed. When the lottery result number “13” is derived, the middle stop switch 37C is notified, and when the lottery result number “14” is derived, the right stop switch 37R is notified that the first stop operation should be performed. To do. As a result, when the stop switch informed by the player is operated for the first time after the game starts, the re-gamer a is established, and the transition from the current RT state to “RT2” can be avoided. it can.

  When the notification by the process of step S224 is performed, the CPU 206 turns off both the defense flag and the bulleted flag state stored in the RAM 210 (step S226), ends the notification control subroutine, and performs other processes. Although the defense flag and the bulleted flag will be described in detail later, the CPU 206 controls the effect based on the image based on the state of these flags. In step S222, when the CPU 206 determines that the current RT state is “RT2” (YES), the process proceeds to step S226 without performing step S224.

  In step S220, if the CPU 206 determines that none of the lottery result numbers “12” to “14” has been derived in the role lottery (NO), the CPU 206 next selects the lottery result numbers “6” to “8”. It is determined whether any one has been derived (step S228). If it is determined that one of the lottery result numbers “6” to “8” (simultaneous winning of a plurality of small roles 2) has been derived (YES), the CPU 206 proceeds to step S224, and any of the small roles 2a to 2h The stop switch of the first stop operation that will be established is notified. That is, as shown in FIG. 8A, when the lottery result number “6” is derived, the left stop switch 37L is selected, and when the lottery result number “7” is derived, the middle stop switch 37C is selected. When the result number “8” is derived, the right stop switch 37R is notified that the first stop operation should be performed. Then, the CPU 206 proceeds to step S226 to turn off both the defense flag and the bulleted flag state stored in the RAM 210, and then ends the ART notification control subroutine to perform other processing.

  In step S228, when the CPU 206 determines that none of the lottery result numbers “6” to “8” has been derived in the winning lottery (NO), the CPU 206 next determines the lottery result number “11” (re-game player a It is determined whether or not (single winning) is derived (step S230). If it is determined that the lottery result number “11” has not been derived (NO), the CPU 206 proceeds to step S226 and turns off both the defense flag and the bulleted flag state stored in the RAM 210. Then, the ART notification control subroutine is terminated and other processing is performed.

  On the other hand, if the CPU 206 determines in step S230 that the lottery result number “11” has been derived in the role lottery (YES), the CPU 206 performs an end lottery (step S232). This end lottery determines either winning or non-winning, and the probability of winning (winning probability) is determined in the effect image control subroutine of FIG. 20 described later. As a result of the end lottery, it is determined whether or not the player has won the game (step S234). If it is determined that the player has not won (NO), the CPU 206 notifies the player that the end lottery has been performed and the result of the end lottery. A notification lottery is performed to determine whether or not (step S238). In this notification lottery, the probability of notifying the player is determined based on the probability that the end lottery will be performed (that is, the probability that the lottery result number “11” will be derived) and the winning probability of the end lottery. On the other hand, when notifying the result of the end lottery, it is preferable to appropriately determine so that a notification indicating that the winning is achieved and a notification indicating that the winning is not performed are performed in a well-balanced manner.

  The CPU 206 determines whether or not notification is determined as a result of the above-described notification lottery (step S238). If it is determined to notify (YES), the state of the defense flag stored in the RAM 210 is determined. Is turned on, and the state of the bulleted flag is turned off (step S240). Then, the CPU 206 displays an image indicating that the end lottery has been performed on the image display device 70 (step S242), and ends the ART notification control subroutine. Here, as will be described in detail later, during the ART, when it is decided to notify that the two character images are competing and the end lottery has been performed by the notification lottery, as an image indicating that Then, an image (see FIG. 24 described later) in which the enemy character attacks the ally character is displayed.

  On the other hand, when it is determined in step S238 that it is determined not to notify the execution of the end lottery (NO), the CPU 206 proceeds to step S226, and the defense flag and the hit flag stored in the RAM 210 are determined. Turn off both states. Then, the ART notification control subroutine is terminated and other processing is performed. If the CPU 206 determines that the end lottery has been won in step S234 (YES), the defense flag stored in the RAM 210 is turned off, and the bulleted flag is turned on (step S244). Then, the process proceeds to step S242, and after displaying an image indicating that the end lottery has been performed on the image display device 70, the ART notification control subroutine is terminated and other processing is performed.

<Explanation of end condition selection lottery processing subroutine>
Next, the contents of the end condition selection lottery process executed in step S208 of the ART notification control subroutine shown in FIG. 18 will be described with reference to the end condition selection lottery process subroutine shown in FIG.

  The CPU 206 receives the No. 1 shown in FIG. 1-No. Which end condition is selected from among the 14 end conditions is determined by lottery based on random numbers, and the selection probability of each end condition to be referred to in this lottery (hereinafter referred to as end condition selection lottery) is determined. That is, the “general gaming” column, “ART A” column, “ART B” column, “MB gaming” column, “first ceiling” column, and “second ceiling” shown in the table of FIG. The selection condition described in the “” column is used to determine which end condition selection lottery is used. Hereinafter, the selection probability group described for each column of the table shown in FIG. 12 is referred to as an end condition selection table.

  First, the CPU 206 determines whether or not the value of the above-described variable RT2 stored in the RAM 210 exceeds 500 (step S260). When the value of the variable RT2 exceeds “500” (YES), the CPU 206 considers that the first ceiling has been reached, and the end condition selection table shown in the “first ceiling” column of the table of FIG. Is used in the selection lottery of the end condition (step S260). If it is determined in step S260 that the value of the variable RT2 does not exceed “500” (NO), the CPU 206 determines whether or not the value of the variable CNT stored in the RAM 110 exceeds “6” ( Step S264). Here, the value of the variable CNT indicates how many times the lottery result that the ART is not started is continuously obtained in the transfer lottery described later. When the value of the variable CNT exceeds “6” (YES), the CPU 206 considers that the second ceiling has been reached, sets the value of the variable CNT to “0” (step S266), and the table of FIG. It is decided to use the end condition selection table shown in the “second ceiling” column of the end condition selection lottery (step S268).

  In step S264, when the CPU 206 determines that the value of the variable CNT does not exceed “6” (NO), the CPU 206 next refers to the lottery table shown in FIG. 11 and determines whether to start ART. A lottery is performed (step S270). That is, in the lottery table of FIG. 11, the type of the combination (either MB combination 1 to 3a or small combination 4) that triggered the transition lottery and the current game state (in general game, during ART, MB game) The start of ART is determined according to the probability determined according to the above.

  Next, as a result of the transfer lottery, the CPU 206 determines whether or not it is determined to start ART (that is, the transfer lottery has been won) (step S272). If the transfer lottery is not won (NO), the CPU 206 adds “1” to the value of the variable CNT stored in the RAM 210 (step S274), and ends the end condition selection lottery processing subroutine. On the other hand, when the transfer lottery is won (YES), the CPU 206, in the table shown in FIG. 12, displays the “in general game” column, the “ART A” column, the “ART B” column, and the “MB” From each end condition selection table shown in the “Now Playing” column, one is selected according to the state when the transfer lottery is performed, and it is determined to be used in the end condition selection lottery (step S276).

  As described above, when the end condition selection table is determined by the processing of step S262, S268, or S276, the CPU 206 performs the end condition lottery based on the determined end condition selection table (step S278), and the table shown in FIG. No. 1-No. One of 14 end conditions is selected. Then, the selected termination condition is stored in a predetermined storage area of the RAM 210 (step S280), and the termination condition selection lottery processing subroutine is terminated. Here, a plurality of end condition lotteries are performed during ART, and as a result, a plurality of end conditions are selected. In this case, the CPU 206 stores each end condition in the RAM 210 so that the order selected by the lottery can be identified. Then, the processing performed immediately before the end condition selection lottery processing in FIG. 19 is started is continued.

<Description of effect image control subroutine>
Next, the contents of the effect image control subroutine for controlling the start and end of ART and for controlling the effect executed during ART will be described with reference to the flowchart shown in FIG.

  In FIG. 20, first, the CPU 206 determines whether or not game result information has been received from the main control circuit 100 (step S290). If it is determined that game result information has not been received (NO), the CPU 206 ends the effect image control subroutine and performs other processing. On the other hand, if it is determined that the game result information has been received (YES), it is stored in the RAM 210 based on the information on the number of medals to be paid out in the current game included in the received game result information. The payout number history is updated (step S292). The payout number history records the number of medals paid out from the slot machine 10 in each game from the current game to the past 17500 times. The payout number history is updated by deleting the oldest payout number record and newly recording the latest payout number.

  Next, the CPU 206 determines whether or not the combination established in the current game is the small combination 4 based on the information indicating the type of established combination included in the received game result information (step S294). . If it is determined that the small role 4 has been established (winned) (YES), the CPU 206 performs the end condition selection lottery process shown in FIG. 19 assuming that the ART start condition is satisfied (step S296). . When the end condition selection lottery process is completed, the CPU 206 determines whether or not the state of the ART flag stored in the RAM 210 is on (step S298). If it is determined in step S294 that the small combination 4 has not won (NO), the process of step S298 is immediately performed.

  If the state of the ART flag is off in step S298 (NO), the CPU 206 next determines whether or not the current gaming state is a general game (step S300). If it is determined that the game is not in a general game (NO), the CPU 206 ends the effect image control subroutine of FIG. 20 and performs other processing. On the other hand, when it is determined that the game is in a general game (YES), the end condition is stored in the predetermined storage area of the RAM 210 in the RAM 210 by the process of step S280 of the end condition selection lottery process shown in FIG. It is determined whether or not (step S302). When determining that the end condition is not stored (NO), the CPU 206 ends the effect image control subroutine of FIG. 20 and performs other processing. On the other hand, when determining that the end condition has been stored (YES), the CPU 206 turns on the state of the ART flag stored in the RAM 210 in order to start ART (step S304).

  Next, the CPU 206 determines the winning probability of the end lottery based on the end condition determined first by the end condition selection lottery process shown in FIG. 19 among the end conditions stored in the RAM 210 (step S306). ). Specifically, first, it is recognized which one of the selection probabilities A to E is set for the portion indicated by “1” in the “end condition” column shown in FIG. Based on the end probability selection table (see FIG. 10) corresponding to the recognized selection probability, one of the six winning probabilities is selected by random number lottery.

  Then, the CPU 206 causes the image display device 70 to display an effect image during ART (step S308). Here, an example of the effect image during ART is shown in FIG. As described above, during the ART, an effect is produced in which the two character images battle each other. At the start of the ART, the teammate character FC and the enemy character are displayed on the image display device 70 as shown in FIG. EC is displayed. Then, the player is informed of the execution of the end lottery and the result of the end lottery through the battle situation between the two. For example, as shown in FIG. 24, an image showing that the end lottery is performed, which is displayed by the process of step S242 in FIG. 18, shows that the enemy character EC attacks the teammate character FC. An image (specifically, a moving image of an attack) is displayed.

  Further, a gauge G for displaying a process until the ART satisfies the termination condition is displayed on the upper left of the screen of the image display device 70. As shown in FIG. 23B, the gauge G includes a selection probability display area (hereinafter referred to as a central gauge) CA that displays a selection probability used when selecting a winning probability in the current end lottery, and a current It includes winning count display areas (hereinafter referred to as stock) SA1 to SA3 for displaying the winning lottery winning count in the end condition. The center gauge CA basically displays a color corresponding to the selection probability, blue for the selection probability B, yellow for the selection probability C, and red for the selection probability D, each in a single color. In the case of the selection probability E, the seven colors constituting the rainbow are displayed as concentric circles. Hereinafter, the color corresponding to the selection probability E is referred to as “rainbow color”. As for the selection probability A, “ALERT” is displayed with white characters on a black background.

  In the stocks SA1 to SA3, the winning number of the end lottery indicated by the end condition is displayed. For example, the current ART termination condition is No. 1 shown in FIG. When it is 1 or 2, only the stock SA1 is lit up. Also, the end condition No. In the case of any of 3 to 6, the stocks SA1 and SA2 are lit up. Further, the end condition No. In the case of any of 7 to 14, stocks SA1 to SA3 are lit and displayed. Each time the end lottery is won during ART, the stocks that are lit up are turned off. Thus, the stocks SA1 to SA3 display the number of winnings indicated by the end condition and also display the remaining number of winnings as the ART progresses. Therefore, the gauge G and its display control correspond to establishment process notifying means.

  When the CPU 206 displays the effect image during ART in step S314, next, the stocks SA1 to SA3 are lighted and displayed in accordance with the number of winning lotteries indicated by the current end condition (step S310). Then, the CPU 206 turns off one of the lit stocks and then displays the color corresponding to the first selection probability on the center gauge CA (step S312). Here, when the stocks SA1 to SA3 are lit up, the stock SA3 is displayed. When the stocks SA1 and SA2 are lit up, only the stock SA2 and the stock SA1 are lit up. Stock SA1. Further, the color displayed on the center gauge CA is a color corresponding to the selection probability shown in the “1” column of the “end condition” column in FIG. Next, the CPU 206 adjusts the winning probability selected in step S306 based on the inserted number history updated in step S202 of FIG. 18 and the payout number history updated in step S292 (step S314). The winning probability adjustment process will be described in detail later with reference to the flowchart of FIG. As described above, when the processing at the start of the ART is completed, the CPU 206 ends the effect image control subroutine and performs other processing.

  If the CPU 206 determines that the state of the ART flag stored in the RAM 210 is on (YES) in the determination process of step S298 described above, based on the previous game and the game state of the current game, ART effect interruption processing for controlling interruption and resumption of the image effect during ART is performed (step S316). This ART effect interruption process will be described later with reference to the flowchart shown in FIG. Next, the CPU 206 determines whether or not the bulleted flag state stored in the RAM 210 is on (step S318). When determining that the state of the hit flag is off (NO), the CPU 206 next determines whether or not the state of the defense flag stored in the RAM 210 is on (step S320). When the CPU 206 determines that the defense flag is turned on (YES), as shown in FIG. 25A, a defense image indicating that the teammate character FC is defending the attack of the enemy character EC is displayed. The information is displayed on the display device 70 (step S322). And it progresses to step S314 mentioned above, performs a winning probability adjustment process, and after adjusting the present winning probability in an end lottery, an effect image control subroutine is complete | finished. On the other hand, if the CPU 206 determines that the defense flag is off (NO), the process proceeds to step S314 as it is to perform the winning probability adjustment process, and then the effect image control subroutine is terminated.

  In addition, when the CPU 206 determines that the bulleted flag state is ON in step S318 (YES), as shown in FIG. 25 (b), the bulleted shot indicating that the teammate character FC has been attacked by the enemy character EC. The image is displayed on the image display device 70 (step S324). Thus, when the end lottery is performed in step S232 of the ART notification control subroutine shown in FIG. 18 and the enemy attack image (see FIG. 24) is displayed (FIG. 18, step S242), the end lottery is performed. Depending on the result, a defense image (non-winning for the end lottery) or a shot image (winning for the end lottery) is displayed. When the bulleted image is displayed in step S324, the CPU 206 next determines whether any of the stocks SA1 to SA3 in the gauge G are lit (step S326). When there is a lit display (YES), the CPU 206 displays one of the lit display stocks off (step S328). That is, when the stocks SA1 and SA2 are lit up, the stock SA2 is turned off, and when only the stock SA1 is lit up, the stock SA1 is turned off.

  Next, the CPU 206 selects the winning probability of the end lottery based on the selection probability for selecting the next winning probability when the end lottery is won in the current end condition (step S330). For example, among the end conditions shown in FIG. It is assumed that ART is performed with the end condition of 6, and the winning probability of the end lottery selected by the selection probability D shown in the “1” column of the “end condition” column is used. In this case, when the end lottery is won, the winning probability of the next end lottery is selected based on the selection probability E shown in the “2” column. That is, at the time of ART disclosure, the winning probability of the end lottery is selected based on the selection probability shown in the “1” column of the “End condition” column shown in FIG. The selection probabilities for the end lottery are selected again using the selection probabilities shown in the respective columns in the order of the "" column and the "3" column.

  Next, the CPU 206 displays a color corresponding to the selection probability used when selecting the next winning probability by the processing of step S330 on the center gauge CA (step S332). Then, the CPU 206 proceeds to step S314 described above to perform a winning probability adjustment process, adjusts the winning probability set in step S330, and then ends the effect image control subroutine. Here, even if the winning probability set in step S330 is adjusted by the winning probability adjustment process in step S314, the color displayed on the central gauge CA is referred to when the winning probability is selected in step S330. It corresponds to the selection probability. When the process of step S314 is completed, the CPU 206 ends the effect image control subroutine and performs other processes.

  In step S326, if the CPU 206 determines that none of the stocks SA1 to SA3 in the gauge G are lit and displayed (NO), the CPU 206 then determines whether or not “ALERT” is displayed on the center gauge CA. Judgment is made (step S334). If it is determined that “ALERT” is not displayed (NO), the CPU 206 displays “ALERT” on the center gauge CA (step S336), and then selects the winning probability of the end lottery based on the selection probability A. (Step S338). Here, the selection probability A is determined so as to select the winning probability of 1/1 with a probability of 100% as shown in FIG. Then, the CPU 206 ends the effect image control subroutine and performs other processing.

  On the other hand, if it is determined in step S334 that the CPU 206 displays “ALERT” (YES), that is, if the end lottery is won while “ALERT” is displayed, the CPU 206 satisfies the current end condition. An end condition satisfaction image indicating this is displayed on the image display device 70 (step S340). This image is, for example, an image (not shown) in which the teammate character FC falls to the ground due to the attack of the enemy character EC following the bullet image displayed in step S324. Next, the CPU 206 determines whether or not the next end condition is stored in the RAM 210 (step S342). Here, the “next end condition” corresponds to the end condition when only one end condition is stored in the RAM 210, and is selected first when a plurality of end conditions are stored. The end condition is applicable.

  If it is determined in step S342 that the next end condition has not been stored (NO), the state of the ART flag stored in the RAM 210 is turned off (step S344), and the effect indicating that the ART has ended. An end image is displayed (step S346). The effect end image is, for example, an image obtained by superimposing the character “END” on the end condition satisfaction image displayed in step S340. Then, the CPU 206 ends the effect image control subroutine and performs other processing. On the other hand, if it is determined in step S342 that the next end condition is stored in the RAM 210 (YES), the CPU 206 notifies that the ART is continued based on the next end condition. . Specifically, as shown in FIG. 26, a continuous image indicating that the teammate character FC that has fallen on the ground rises is displayed on the image display device 70 (step S348). Then, the CPU 206 turns on and displays the gauges G stocks SA1 to SA3 based on the following termination conditions (step S350).

  Next, the CPU 206 proceeds to step S330, selects the winning probability of the end lottery based on the first selection probability defined in the next end condition, and then focuses on the color corresponding to the first selection probability in step S332. Display on gauge CA. And it progresses to step S314, and after performing the winning probability adjustment process mentioned later and adjusting the winning probability selected by step S330, an effect image control subroutine is complete | finished.

<Description of ART effect interruption processing subroutine>
Next, detailed contents of the ART effect interruption process executed in step S316 of the effect image control subroutine shown in FIG. 20 will be described with reference to the flowchart shown in FIG. As shown in the flowchart of FIG. 20, this process is executed when the ART flag is on (FIG. 20, step S298, YES).

  First, the CPU 206 changes the game state from the general game to any of the MB games 1 to 3 based on information indicating each game state included in the game result information received in the previous game and the current game. It is determined whether or not the transition has been made (step S360). When it is determined that the game state has shifted from the general game to the MB game (YES), the CPU 206 turns on the state of the interruption flag stored in the RAM 210 (step S362). Next, the CPU 206 switches the ART effect image displayed during the currently displayed ART to the effect image displayed during the MB game (step S364). Then, the ART effect interruption process subroutine is terminated, and the process proceeds to the process of step S318 of the effect image control subroutine shown in FIG.

  In the determination process of step S360, if the CPU 206 determines that the game state has not shifted from the general game to the MB game (NO), it is included in the game result information received in the previous game and the current game. Based on the information indicating each game state, it is determined whether or not the game state has shifted from any of MB games 1 to 3 to a general game (step S366). If the CPU 206 determines that the gaming state has not shifted from the MB game to the general game (NO), the ART effect interruption processing subroutine is terminated, and the process proceeds to step S318 of the effect image control subroutine shown in FIG. Transition.

  On the other hand, when the CPU 206 determines that the game state has shifted from the MB game to the general game (YES), the CPU 206 turns off the state of the interruption flag stored in the RAM 210 (step S368). Next, as in step S314 in FIG. 20, the CPU 206 calculates the current winning probability based on the inserted number history updated in step S202 in FIG. 18 and the payout number history updated in step S292 in FIG. Adjustment is made (step S370). Then, after displaying the effect image displayed during ART again from the state displayed immediately before the MB game is started (step S372), the CPU 206 ends the ART effect interruption processing subroutine, and FIG. The process proceeds to step S318 in the effect image control subroutine shown.

<Description of Winning Probability Adjustment Processing Subroutine>
Next, the flowchart shown in FIG. 22 shows the detailed contents of the winning probability adjustment process executed in step S314 of the effect image control subroutine shown in FIG. 20 and step S370 of the ART effect interruption process subroutine shown in FIG. The description will be given with reference.

  First, the CPU 206 refers to the inserted number history and the payout number history respectively updated by the processing of step S202 of the ART notification control subroutine shown in FIG. 18 and step S292 of the effect image control subroutine shown in FIG. Then, the cumulative inserted number and cumulative payout number history from the current game to the past 400 games are calculated (step S380). Then, it is determined whether or not a value obtained by dividing the cumulative payout number by the cumulative input number (hereinafter referred to as an expected value) is “3” or more (step S382). When it is determined that the expected value is “3” or more (YES), the winning probability of the currently set end lottery is set to ½ (step S384), the winning probability adjustment processing subroutine is ended, Proceed to the next process.

  On the other hand, when the CPU 206 determines that the expected value calculated in step S382 is less than “3” (NO), it refers to the input number history and the payout number history again, and from the current game to the past 6000 games. The cumulative input number and cumulative payout number history up to are calculated (step S386). Then, it is determined whether or not the expected value calculated by dividing the cumulative payout number by the cumulative input number is “1.5” or more (step S388). When it is determined that the expected value is “1.5” or more (YES), the process proceeds to step S384, and the winning probability of the currently set end lottery is set to ½. Then, the winning probability adjustment processing subroutine is finished, and the process proceeds to the next processing.

  Further, when the CPU 206 determines that the expected value calculated in step S386 has not exceeded “1.5” (NO), the CPU 206 refers to the inserted number history and the paid out number history again, and determines the past from the current game. Cumulative inserted number and accumulated payout number history up to 17500 games are calculated (step S390). Then, it is determined whether or not the expected value calculated by dividing the cumulative payout number by the cumulative input number exceeds “1.2” (step S392). If it is determined that the expected value exceeds “1.2” (YES), the process proceeds to step S384, and the winning probability of the currently set end lottery is set to ½. Then, the winning probability adjustment processing subroutine shown in FIG. 22 is terminated, and the process proceeds to the next processing. On the other hand, when it is determined in step S380 that the expected value calculated in step S390 did not exceed “1.2” (NO), the CPU 206 ends the winning probability adjustment processing subroutine as it is.

<Description of slot machine operation>
During the general game, when any of the MB roles 1 to 3b is won in the role lottery and the fact is transmitted from the main control circuit 100 to the sub-control circuit 200 (step S58 in FIG. 14), the CPU 206 receives it. Then, it is recognized that the MB combination has been won (step S200, YES in FIG. 18). At this time, if the first ceiling or the second ceiling has not been reached (FIG. 19, steps S260, S264, NO), the transfer lottery to ART is performed based on the transfer lottery table shown in FIG. 11 (FIG. 19). , Step S270). As a result of the game, when the small role 4 wins and the CPU 206 recognizes that (FIG. 20, step S296, YES), a transition lottery to ART is performed (step S298 in FIG. 20). Then, when the transfer lottery is won (FIG. 19, step S272, YES), the end condition is selected based on the selection table shown in FIG. 12 (FIG. 19, step S278) and stored in the RAM 210 (FIG. Step S280).

  Further, the CPU 206 determines whether or not the end condition is stored in the RAM 210 when the ART is not being played (FIG. 20, step S298, NO) and the general game is being played (FIG. 20, step S300, YES). The game is checked (the figure, step S302), and if the end condition is stored, the ART is started (the figure, step S304). At the start of ART, the winning probability of the end lottery is set based on the end condition (step S314 in the figure). At this time, the total number of medals inserted from the past game to the current game and the payment are determined. If it is determined that the number of payouts is too large based on the total number of medals issued, the winning probability of the end lottery once set is increased (see FIG. 22). Thus, when it is determined that the number of medals to be paid out is too large, the winning probability of the end lottery is increased, the ART end condition is easily established in a short period, and the ART is ended early, The number of medals to be paid out to the player is reduced as much as possible.

  During ART, if one of the small roles 2 is won in the role lottery (FIG. 18, step S228, YES), the stop switch for the first stop operation (FIG. 8) where any of the small roles 2a to 2h will win. (See (a)) is notified to the player (FIG. 18, step S224). Further, when the re-gamer (except when the re-gamer a alone is elected) is won in the role lottery when the RT state is “non-RT” or “RT1” (FIG. 18, step S220, YES). A stop switch (see FIG. 8B) for the first stop operation that can avoid the transition to “RT2” is notified to the player (step S224 in FIG. 18).

  When ART is started, an effect image (see FIG. 23A) in which the teammate character FC and the enemy character EC battle each other is displayed on the image display device 70 (FIG. 20, step S308). In addition, the effect image also displays a gauge G (see FIG. 23B) for displaying the establishment process of the ART termination condition. When an end lottery is performed during ART (FIG. 18, step S230, YES → S232), an image (see FIG. 24) in which the enemy character EC attacks the ally character FC is displayed (FIG. 18, step). S242) If the end lottery is not won (FIG. 20, step S320, YES), an image (see FIG. 25A) in which the teammate character FC defends against an enemy attack is displayed (FIG. 20, step S322). ) When the end lottery is won (FIG. 20, step S318, YES), an image (see FIG. 25B) in which the friendly character FC is attacked by an enemy is displayed (FIG. 20, step S324). . Thus, when the end lottery is performed, an image indicating that is displayed, and then an image indicating the result of the end lottery is displayed.

  In addition, when the winning lottery is won, one of the gauges G SA1 to SA3 that is lit up is turned off (FIG. 20, step S328), and the winning probability of the final lottery is selected again. The color corresponding to the selection probability is displayed on the center gauge CA (FIG. 20, step S332). In this way, each time the winning lottery is won, the stocks SA1 to SA3 are turned off one by one to indicate how many times the winning lottery will end and the ART will end, giving the player a sense of tension. It is possible to improve the interest of the game by having. In addition, by notifying the player of the selection probability used when selecting the winning probability of the end lottery, it is possible to raise expectations regarding the level of the winning probability of the end lottery, thereby reducing the player's gaming motivation. Fear can be reduced. In addition, each time the winning lottery is won, the color of the center gauge changes according to the selection probability set in the ending condition, so that the player's expectation for the sustainability of ART may be changed. Yes, this can improve the interest during ART.

  Then, in the end condition shown in FIG. 12, the ART is continued under the winning probability of the end lottery selected based on the last selection probability (at this time, all the stocks SA1 to SA3 are displayed off). When the end lottery is won (FIG. 20, steps S318, YES, S326 and S334, NO), the letters “ALERT” are displayed on the center gauge CA (FIG. 20, step S336). At this time, the winning probability of the end lottery is 1/1 (FIG. 20, step S338). Therefore, when the end lottery is performed in the subsequent game, the winning lottery is always won, and the image display device 70 shows that the friend character FC is the enemy. In response to the attack (FIG. 20, step S324), an image that falls to the ground (an image that satisfies the end condition) is displayed (FIG. 20, step S340).

  If the next end condition is not stored in the RAM 210 (FIG. 20, step S342, NO), an effect end image indicating that the ART has ended is displayed as it is (FIG. 20, step S346). When the end condition is stored (FIG. 20, step S342, YES), an image (see FIG. 26) in which the teammate character FC stands up is displayed (FIG. 20, step S348). Further, at this time, the stocks SA1 to SA3 of the gauge G are lit and displayed according to the number of wins (also referred to as the number of selection probabilities) determined in the next end condition (FIG. 20, step S350). Then, one of the lit stocks is turned off, and the winning probability of the ending lottery is set according to the first selection probability defined in the next ending condition (step S330 in FIG. 20). Thereafter, the color corresponding to the first selection probability described above is displayed on the center gauge CA (FIG. 20, step S332), and ART based on the next end condition is started.

  In this way, even if the next end condition is stored in the RAM 210, in other words, even if the continuation of ART is scheduled, it is displayed once in the process of reaching the effect end image. An end condition satisfaction image is displayed.
