Description

  The present invention relates to a slot machine that may win a plurality of roles by lottery processing.

  Conventionally, in a slot machine, in order to entertain a player, a plurality of types of games are provided to advance the game. Some of these games are called normal games or special games.

  In the above-mentioned normal game, in order to make a combination of symbols corresponding to the winning combination in the lottery process, the player performs a so-called eye-opening operation so that the symbol is positioned on the effective line. It is a game that allows you to win a prize.

  On the other hand, the special game is a game that is advantageous to the player over the normal game, and includes a game that has a high possibility of winning the winning combination without performing a pushing operation (for example, Patent Document 1).

As described above, the special game is a game that is more advantageous to the player than the normal game, so in the special game, the probability of winning the role that requires a pressing operation is lower than the probability of winning in the normal game. Although it is conceivable to increase the possibility of winning a prize without performing a pressing operation, reducing the probability of winning a certain role in a special game is not preferable from the viewpoint of the interest of the game.
JP 2001-129157 A

  However, it is not preferable to include a role requiring a pressing operation in a special game because it is necessary to perform the pressing operation even in a special game, and it becomes difficult for a player to be advantageous.

  The present invention has been made in view of the above-described points, and the purpose of the present invention is to reduce the probability of winning a combination in a special game without lowering the probability of winning a normal game, and without using it. The object is to provide a slot machine that can win a prize.

  In order to achieve the above object, in the present invention, in one determination collation data among a plurality of determination collation data, one region and another region are not overlapped with each other, and other In the judgment collation data, one area is overlapped with another area, and the size of the other area is made different between the one in one judgment collation data and the other in the judgment collation data.

Specifically, the slot machine according to the present invention is:
It is a slot machine in which the progress of a game is determined by the display mode when a plurality of rotatable reels to which a plurality of types of symbols are attached are stopped based on the player's operation. And
A role lottery means for drawing a type of role;
The role lottery means
A random number generating means for generating a random number;
Random number determination means for storing a plurality of determination verification data for determining the type of the combination based on the value of the random number, wherein each of the plurality of determination verification data includes one area and the one area Each of the plurality of areas is defined by an upper limit value and a lower limit value, and the random number value of the plurality of areas is defined. Random number determining means for determining the type of the role according to the area to which the belongs, and
One determination collation data among the plurality of determination collation data is determined so that the one area and the other area do not overlap each other,
The other judgment collation data among the plurality of judgment collation data is determined such that at least one of the plurality of areas overlaps the other area,
The size of the one area in the one determination collation data matches the size of the one area in the other determination collation data, and
The size of the other area in the one determination collation data is different from the size of the other area in the other determination collation data.

  The lottery means for performing the lottery of the type of the role includes a random number generation means and a random number determination means.

  The random number generation means generates a random number so that the value of the random number is included in a predetermined range.

  The random number determination means determines the type of the combination based on the random number value generated by the random number generation means. The random number determination means stores a plurality of determination verification data. Each of the plurality of determination collation data includes a plurality of regions. In particular, the plurality of areas include two areas, one area and another area different from the one area. Each of the plurality of regions is delimited by an upper limit value and a lower limit value. That is, in each of the plurality of regions, the upper limit of the region is defined by the upper limit value, and the lower limit of the region is defined by the lower limit value. The upper limit value and the lower limit value determine the position as a storage area in the determination collation data. Further, the size of the storage area in the determination collation data is determined by the difference between the lower limit value and the upper limit value.

  The random number determination means determines the type of the combination according to which of the plurality of areas the random number value generated by the random number generation means belongs. That is, each of the plurality of areas is determined according to the type of combination. For example, if the type of role consists of three types of roles, special role, small role, and re-playing role, it is divided into four areas, which are defined as “multiple areas”, and the first area is It is determined to correspond to the special combination, the second area corresponds to the small combination, and the third area corresponds to the re-playing combination. Further, the fourth area is made to correspond to the out-of-range area.

  In the case of the above-described example, the “one area” can be any one of the area corresponding to the special combination, the area corresponding to the small combination, and the area corresponding to the re-playing combination. In addition, the “other area” can be either an area corresponding to a special role, an area corresponding to a small role, or an area corresponding to a replaying role, and is an area different from “one area”. is there.

  Here, “the other area” is different from “one area”, and the type of the role corresponding to “one area” and the type of the role corresponding to “other area” are different from each other. That means.

  When a small role consists of multiple types, “one area” is the region corresponding to one type of small role, and “other area” is another type different from one type of small role It can be set as the area corresponding to the small part. For example, when the small role is composed of three types of a bell role, a watermelon role and a cherry role, “one area” is an area corresponding to the bell role, and “other area” is different from the bell role. It can be set as the area corresponding to the watermelon role.

  The special role described above is a role for shifting to a special game that is advantageous to the player. For example, bonuses such as a big bonus and a regular bonus described later correspond to this combination. The small role is a role for paying out game media. For example, a combination such as a watermelon or a bell described later corresponds to this combination. Furthermore, the re-gamer is a role that gives a profit that allows a new game to be started without making an investment by introducing a game medium. For example, the replay described later corresponds to this combination. Also, an outage does not give any benefit to the player.

  By defining a plurality of areas in this way, when the value of the random number generated by the random number generation means belongs to the area corresponding to the special combination, it is determined as a special combination. Further, when the random number value belongs to the area corresponding to the small combination, it is determined to be a small combination, and when the random number value belongs to the area corresponding to the re-playing combination, it is determined to be the re-playing combination.

  The plurality of determination collation data described above includes at least two pieces of determination collation data: one determination collation data and another determination collation data different from the one determination collation data. The one determination collation data is determined so that one area and another area do not overlap each other. Here, “so as not to overlap” means that “one region” and “other region” are determined at positions separated from each other in one determination collation data, or “one region”. It means that “another region” is defined at an adjacent position.

  In one determination collation data, it is only necessary to determine that “one region” and “other region” do not overlap with each other, and other than two regions of “one region” and “other region”. About another area | region, it is good also as a structure which does not overlap even if it is the structure which overlaps.

  Further, the other determination collation data is determined such that one area overlaps with another area. Here, “to overlap” means that a part of both “one area” and “other area” overlaps each other in one of the other judgment matching data, or one area Is the state of being entirely included in the other region. Furthermore, the “one region” and the “other region” coincide with each other, and the entire one region and the other region overlap each other. For example, the upper limit of “One Area” is larger than the lower limit of “Other Area” even though the upper limit of “Other Area” is larger than the lower limit of “One Area” Or if the upper limit value of “One Area” is larger than the lower limit value of “One Area”, even though the upper limit value of “One Area” is larger than the lower limit value of “Other Area” It is. In addition, when the upper limit of “other area” is less than or equal to the upper limit of “one area”, the lower limit of “other area” is greater than or equal to the lower limit of “one area” There is.

  If the random number generated by the random number generator belongs to this overlapping area, both the combination corresponding to “One Area” and the combination corresponding to “Other Area” are selected. And For example, when “One Area” is an area corresponding to a special role and “Other Area” is an area corresponding to a small role, an area where “One Area” and “Other Area” overlap. In addition, when a random number value belongs, it is assumed that both the special combination and the small combination are won.

  In addition, when a small role consists of multiple types, when a random number value belongs to an area where "one area" and "other area" overlap, one type of small role and another type Suppose you have been elected redundantly with the other small part. For example, there are three types of small roles: bell role, watermelon role, and cherry role, where “one area” corresponds to the bell role and “other area” is a watermelon role different from the bell role. If the random number value generated by the random number generation means belongs to both the "one area" and the "other area" when the corresponding area is used, it overlaps with the bell role and the watermelon role. Suppose you win.

  “At least” in the above-mentioned “so that at least one of the plurality of regions overlaps with the other region” means that two regions of “one region” and “other region” are It is only necessary to overlap, and other areas other than the two areas of “one area” and “other area” may be configured to be overlapping or not overlapping. Say.

  The size of “one area” in “one determination collation data” matches the size of “one area” in “other judgment collation data”. As described above, the size of the storage area in the determination collation data is determined by the difference between the lower limit value and the upper limit value. That is, the size of “one area” in “one determination collation data” is determined by the difference between the lower limit value and the upper limit value of “one area” in “one judgment collation data”. In addition, the size of “one area” in “other determination collation data” is determined by the difference between the lower limit value and the upper limit value of “one area” in “other determination collation data”. That the size of “one area” is the same means that the size of “one area” is the same in both “one judgment collation data” and “other judgment collation data”.

  It should be noted that the size of “one area” may be the same between “one determination collation data” and “other determination collation data”, and the position of “one area” may be different. In other words, even if the position of “one area” in “one determination collation data” and the position of “one area” in “other determination collation data” are different, they may have the same size.

  The size of “other area” in “one determination collation data” is different from the size of “other area” in “other judgment collation data”. The size of the “other region” in the “one determination collation data” is determined by the difference between the lower limit value and the upper limit value of the “other region” in the “one determination collation data”. Further, the size of “other area” in “other determination / collation data” is determined by the difference between the lower limit value and the upper limit value of “other area” in “other determination / collation data”. The difference in the size of the “other area” means that the “other area” differs between the size of “one determination collation data” and the size of “other determination collation data”.

  Also, the size of the “other area” is different from the “other area” in the “other judgment collation data” in the “other judgment collation data”. Both the case where the “other area” becomes larger and the case where it becomes smaller are included. In particular, it is preferable that the size of “other area” in “other determination collation data” is larger than the size of “other area” in “one determination collation data”. By doing in this way, the lottery probability of the combination corresponding to “another area” can be increased, and the player's expectation can be enhanced.

  As described above, in one determination collation data, it is sufficient that two areas of “one area” and “other area” do not overlap, and “one area” and “other area” Other areas other than these two areas may be configured to overlap or not to overlap. Further, in the other determination collation data, it is sufficient that the two areas of “one area” and “other area” overlap, and two areas of “one area” and “other area”. About another area | region other than, it is good also as a structure which overlaps and is not overlapped.

  With the above-described configuration, the “other area” can be changed in size between “one determination collation data” and “other determination collation data”. In “the determination collation data”, “other area” and “one area” do not overlap, but in “other determination collation data”, “other area” and “one area” overlap. You can

  By doing so, the probability of winning the combination corresponding to “one region” is maintained when “one judgment matching data” is selected and when “other judgment matching data” is selected. However, it is possible to change the probability of winning the combination corresponding to the “other area”, and to change the progress and development of the game.

  In addition, when “other area” is an area corresponding to a winning combination that can be won without pressing the eye, and “one area” is an area corresponding to a winning action that requires the pressing action. Therefore, it is possible to increase the possibility of winning the winning combination corresponding to the “other area” without decreasing the probability of winning the winning combination corresponding to the “one area”.

  The other area in the other determination collation data is preferably defined over the entire other determination collation data.

  Here, “determined over the entire other judgment collation data” means that the upper limit value of “other area” in “other judgment collation data” is the upper limit value of “other judgment collation data” itself. And the lower limit value of “other area” in “other judgment collation data” matches the lower limit value of “other judgment collation data” itself.

  In this way, when “other judgment matching data” is selected, a role corresponding to “other area” can always be won, and a role corresponding to “other area” can be won. Can increase the sex. In addition, when a role corresponding to “other area” is selected as a role that can be won without pressing the eye, the role corresponding to “other area” is always won without pressing the eye. be able to.

The upper limit value that defines the one area in the one determination collation data matches the upper limit value that defines the one area in the other determination collation data, and
It is preferable that a lower limit value that defines the one region in the one determination collation data matches a lower limit value that defines the one region in the other determination collation data.

  The upper limit value that defines “one area” is the same value for “one determination collation data” and for “other determination collation data”. Further, the lower limit value that defines “one region” is the same value in “one determination collation data” and “other determination collation data”. Therefore, the “one region” is not changed in size or position in “one determination collation data” or “other judgment collation data”. In this way, even when “one determination collation data” is selected or “other judgment collation data” is selected, the processing can be made common, and the random number determination processing is facilitated. be able to.

Based on the lottery result by the combination lottery means, a game control means that selects and performs either a normal game or a special game that is more advantageous to the player than the normal game;
It is desirable to include a judgment collation data selecting means for selecting the one judgment collation data for the normal game and selecting the other judgment collation data for the special game.

  The slot machine of the present invention further includes game control means and determination / collation data selection means. The game control means selects either a normal game or a special game based on the lottery result by the combination lottery means. Here, the special game is a game that can be more advantageous to the player than the normal game.

  The judgment collation data selection means selects one judgment collation data in the normal game, and selects other judgment collation data in the special game.

  By doing in this way, when the combination corresponding to “other area” is a combination that can be won without pressing the other side, other determination matching data is selected in the special game. Therefore, the probability of winning a role corresponding to “One Area” is lower than that of a normal game, and the possibility of winning a role corresponding to “Other Area” without pushing up is increased. Can do.

  In a special game, the probability of winning a winning combination can be made to win a winning combination without lowering the probability than a normal game, and the fun of the game can be enhanced.

  Embodiments of the present invention will be described below with reference to the drawings.

  The start switch 42 and the three stop switches 44a, 44b, and 44c are switches that are operated by the player to advance the game. When the player operates the start switch 42, rotation of three reels 30L, 30C, and 30R described later is started. Further, when the player operates the three stop switches 44a, 44b, and 44c, the reels 30L to 30R corresponding to the operated stop switches are stopped.

  The functions of the 1 bet switch 62, the 2 bet switch 64, and the maximum bet switch 66 will be described later.

<Reel display window 50 and reels 30L, 30C, 30R>
As shown in FIGS. 1 and 2, a reel display window 50 is formed at a substantially central portion of the front surface of the front door 40. As shown in FIG. 2, the three reels 30 </ b> L to 30 </ b> R are rotatably accommodated in the reel unit 28. The reel unit 28 has a front surface 29 open, and the player can visually recognize the type of symbols located on the front surface 29 of the reel unit 28, as will be described later. The reel unit 28 is supported by a support plate 26 fixed to the base portion 20. When the front door 40 is closed, the reel display window 50 is positioned in front of the front surface 29 of the reel unit 28. The reel display window 50 is covered with a transparent member, and when the front door 40 is closed, the player visually recognizes the types of symbols drawn on the reels 30L to 30R via the reel display window 50. be able to.

  A plurality of types of symbols are attached to each of the three reels 30L to 30R. The types of symbols are those that can be identified by the player, such as the number “7” or the fruit “cherry”. As will be described later, when the three reels 30L to 30R are stopped, nine symbols are stopped and displayed in the reel display window 50 so as to be visible.

<Reels 30L, 30C, 30R and stop switches 44a, 44b, 44c>
The left reel 30L corresponds to the left stop switch 44a, the middle reel 30C corresponds to the center stop switch 44b, and the right reel 30R corresponds to the right stop switch 44c. Thus, when the player operates the left stop switch 44a, the left reel 30L stops, when the player operates the center stop switch 44b, the middle reel 30C stops, and the player presses the right stop switch 44c. When operated, the right reel 30R stops.

<Reel display window 50 and winning lines L1 to L5>
As described above, the reel display window 50 is covered with a transparent member. As shown in FIG. 1, five winning lines L <b> 1 to L <b> 5 are drawn on the reel display window 50. By doing in this way, the player can visually recognize the kind of symbol through the reel display window 50 and can also visually recognize the five winning lines L1 to L5 on the reel display window 50. .

  The winning line L1 is a middle straight line extending in the horizontal direction, the winning line L2 is an upper straight line extending in the horizontal direction, and the winning line L3 is a lower straight line extending in the horizontal direction. The winning line L4 is a straight line extending from the upper left to the lower right, and the winning line L5 is a straight line extending from the lower left to the upper right.

<Bet switches 62, 64 and 66 and winning lines L1 to L5>
When a predetermined number or more medals are inserted into the medal insertion slot 46 of the operation panel 41 described above, the number of medals inserted by a medal counter (not shown) is counted, and the number is stored as the number of credits. The 1-bet switch 62 described above is a switch for setting one medal out of the stored credits to be a game bet. Further, the 2-bet switch 64 is a switch for targeting two medals out of the number of credits for game betting, and the maximum bet switch 66 is a game betting for three medals out of the credit number. It is a switch for making it an object of.

  As described above, the five reel lines L1 to L5 are drawn on the reel display window 50. When the player operates the 1-bet switch 62, one of the five pay lines, for example, the pay line L1 is activated. When the 2-bet switch 64 is operated, three of the five pay lines, for example, the pay lines L1, L2, and L3 are activated. When the maximum bet switch 66 is operated, all five pay lines, that is, L1, L2, L3, L4, and L5 are activated. In this way, the three bet switches 62, 64 and 66 function as selection means for determining the number of medals to be a game bet and validating the pay lines L1 to L5.

<Effective line>
As described above, the three bet switches 62, 64, and 66 function as a selection unit that activates the pay lines L1 to L5 when operated by the player. When the player operates the 1 bet switch 62, the pay line L1 is activated, when the 2 bet switch 64 is operated, the pay lines L1, L2, and L3 are activated, and when the maximum bet switch 66 is operated, All of the pay lines L1 to L5 are activated. As described above, the activated winning line is referred to as an activated line.

  The combination of symbols stopped on the active line is subject to determination as to whether or not a prize has been won. For example, when the combination of “7”-“7”-“7” is aligned on the above-described effective line L1, it is determined that the winning combination of big bonus has been won. The type of combination will be described later. Further, when the combination of symbols that do not constitute a combination on the active line L1 is stopped, it is determined that no winning is made. On the other hand, even if it is a winning line, when the winning line is not activated, even if a combination of “7”-“7”-“7” is aligned on the winning line, The winning line is not subject to the determination of whether or not a prize has been won.

<Image display device 34>
An image display device 34 is provided on the upper portion of the front door 40. An effect image is displayed on the image display device 34. The effect image is an image that is displayed as the game progresses, and is mainly an image that includes various types of information related to the game.

  There are two types of effect images displayed on the image display device 34: one that displays various types of information in the form of characters, and the other that displays in the form of drawings other than characters. The information displayed in the character mode is mainly used for allowing the player to visually recognize various information directly. In this case, a symbol that visually represents a word as a means for transmitting human intention and emotion, such as a numerical value, alphabet, hiragana, katakana, and kanji, is used as the character. Further, the information displayed in the graphic form is mainly used for indirectly making the player visually recognize various kinds of information. In this case, an image of a character indicating a creature such as a person or an animal, a pseudo life form such as a robot, or an image indicating other machinery, a building, a landscape, or the like is included.

<Main control board 32>
The main control board 32 is a control board for controlling the start and stop of the rotation of the three reels 30L, 30C and 30R and for controlling the entire game such as the progress of the game performed in the slot machine 10. The main control board 32 includes a CPU (Central Processing Unit) (not shown) for performing arithmetic operations, a ROM (Read Only Memory) (not shown) that stores a game program, and a RAM (Temporarily storing each data). Random access memory) (not shown). For example, the ROM stores a program for executing a program shown in FIG. 4 to be described later, a normal game probability table 127 and a special game probability table 128 shown in FIG. The RAM also stores variable values used in this program. These CPU, ROM, and RAM are electrically connected by an input / output bus so that data signals and address signals can be input / output.

  The main control board 32 is electrically connected to the bet switches 62, 64 and 66 described above. When the player operates the bet switches 62, 64 and 66, a bet instruction signal is issued from each of the bet switches 62, 64 and 66 to the main control board 32.

  Further, the main control board 32 is electrically connected to the above-described start switch 42 and the three stop switches 44a, 44b and 44c. When the player operates the start switch 42 or the three stop switches 44a, 44b and 44c, an operation signal is issued from the start switch 42 or the three stop switches 44a, 44b and 44c to the main control board 32. When a signal is issued from the start switch 42 to the main control board 32, the main control board 32 controls the rotation of the three reels 30L, 30C and 30R. When a signal is issued to the main control board 32 from the stop switch 44a, 44b or 44c, the main control board 32 stops the reel corresponding to the operated stop switch among the three reels 30L, 30C and 30R. Take control.

<Sub control board 52>
As shown in FIG. 2, the sub control board 52 is disposed on the upper part of the back surface of the front door 40. The sub-control board 52 is a board that mainly controls effects during the game. For example, control is performed such that an effect image is displayed on the image display device 34, a sound effect or music is emitted from the speaker 36, and the lamp 38 is turned on or blinked. The sub-control board 52 includes a CPU (not shown) that performs calculations, a ROM (not shown) that stores effect programs and effect data, and a RAM (not shown) that temporarily stores each data. Including. The RAM stores variable values used in the effect program. These CPU, ROM, and RAM are electrically connected by an input / output bus so that data signals and address signals can be input / output.

  The sub control board 52 is electrically connected to the main control board 32 by a harness (not shown). The main control board 32 transmits commands, information, and the like to the sub control board 52. The above-described main control board 32 controls the entire game in an integrated manner, while the sub control board 52 belongs to the lower level of the main control board 32 and is based on commands, information, etc. sent from the main control board 32. To control the entire production.

<Games in the slot machine 10>
A game in the slot machine 10 is a game in which a game result is determined by a combination of symbols determined by stop positions of the plurality of stopped reels 30L, 30C, or 30R. The player operates the three stop switches 44a, 44b and 44c so that the combination of symbols to be stopped on the active line becomes a combination of symbols constituting a predetermined role, and turns the reels 30L, 30C or 30R. Stop. The combination is determined by a lottery process of the combination lottery means 120 described later. As will be described later, the lottery process determines winning or losing, and winning means that at least one type of combination is determined from a plurality of types of combinations.

  In addition, a game performed in the slot machine 10 is performed each time the player operates the start switch 42, and a game that can be repeated as a single process from the start of rotation to the stop of rotation of the plurality of reels 30L, 30C, or 30R. It is. This single-stroke game is called a unit game.

  The types of the above-described combinations include, for example, special combinations, small combinations, and replay combinations. The special role is a role that can shift from a normal game to a special game (a game advantageous to the player). The special combination includes a big bonus (hereinafter referred to as BB combination) and a regular bonus (hereinafter referred to as RB combination).

  The above-mentioned BB combination is a combination to shift to a BB game which is one of special games. This BB game is a game that can be transferred to a privilege game a plurality of times. This privilege game is a game that performs a game in which a predetermined role is won with high probability, and is a game that can give a player a privilege that increases the possibility that the player will acquire more medals. In this BB game, the privilege game can be repeated until a predetermined end condition is satisfied, for example, until the number of medals to be paid out exceeds a predetermined number.

  In addition, the RB combination is a combination to shift to the RB game that is one of the special games. This RB game is a game in which a game corresponding to a privilege game during the BB game is played, that is, a game in which a predetermined role is won with a high probability is performed a predetermined number of times under a certain condition.

  Further, the small combination is a combination for paying out a predetermined number of medals. A small role has a plurality of types of roles, and the name of the role is often used by using the types of symbols attached to the three reels 30L, 30C, or 30R. For example, the types of symbols include “watermelon”, “bell”, “cherry” and the like. For this reason, a small role in which the pattern “watermelon” is aligned on the effective line is referred to as a watermelon role, and a small role in which the pattern “bell” is aligned on the effective line is referred to as a bell role. Further, when the symbol “cherry” of the left reel 30L is stopped and displayed on the active line, it is assumed that a winning is made regardless of the types of symbols of the middle reel 30C and the right reel 30R. This role is called the cherry role.

  Furthermore, the re-game role is a role that allows a re-game (hereinafter referred to as “replay” or “RP”) that maintains the number of bets (the number of bets) in the currently played game.

<< Functions of Slot Machine 10 >>
FIG. 3 is a functional block diagram showing an outline of main control functions in the slot machine 10. As shown in FIG. 3, the slot machine 10 mainly includes an operation unit 500, a main control unit 100, and a symbol display unit 400.

<Operating means 500>
The operation means 500 is operated by the player, and issues a signal indicating that the operation has been performed to the main control means 100 described later based on the player's operation. The operation means 500 preferably includes a start switch 42 and stop switches 44a to 44c. When the start switch 42 is operated by the player, the start switch 42 issues a signal indicating that the start switch 42 has been operated to the main control means 100 described later. Further, when each of the stop switches 44a to 44c is operated by the player, the stop switch 44a to 44c issues a signal indicating that it has been operated to the main control means 100 described later.

  As described above, a single process game that is performed after a plurality of reels 30L, 30C, or 30R is rotated and then stopped is referred to as a unit game. The signals issued from the start switch 42 to the main control means 100 start the rotation of the three reels 30L, 30C and 30R, thereby determining the start timing of the unit game. A signal issued from the start switch 42 to the main control means 100 is referred to as a start signal.

  In addition, the corresponding reels among the three reels 30L, 30C, and 30R are stopped by a signal issued from each of the stop switches 44a to 44c to the main control means 100, and a trigger for ending the unit game is determined. A signal issued from each of the stop switches 44a to 44c to the main control means 100 is referred to as an end signal. Accordingly, the unit game is started based on the start signal being issued, and the unit game is ended based on the end signal being issued.

  The number of medals to be bet on the game is determined by a signal issued from the 1-bet switch 62, 2-bet switch 64 or maximum bet switch 66 to the main control means 100. For example, one medal is targeted for a game bet by a signal issued from the 1 bet switch 62 to the main control unit 100, and two medals are received by a signal issued from the 2 bet switch 64 to the main control unit 100. Are bets for gaming, and three medals are targeted for gaming bets by a signal issued from the maximum bet switch 66 to the main control means 100.

<Main control means 100 (game control means)>
In addition to the operation means 500 described above, the symbol display means 400 is electrically connected to the main control means 100. The main control means 100 controls the entire game such as the progress of the game and issues a control signal to the symbol display means 400. The main control means 100 preferably comprises the main control board 32 described above.

  As described above, the operation means 500 is electrically connected to the main control means 100. An end signal is issued to the main control means 100 from each of the stop switches 44 a to 44 c of the operation means 500. By detecting the order and timing of the end signals generated from each of the stop switches 44a to 44c, the main control means 100 can obtain a plurality of types of operation modes of the three stop switches 44a to 44c.

  The main control means 100 is composed of a combination lottery means 120, a reel drive control means 130, and a symbol detection means 150.

<Role lottery means 120 (lottery means)>
The role lottery means 120 performs a lottery of a predetermined role. As described above, the combination includes a special combination, a small combination, and a replay combination.

  The special role is a role that shifts from the normal game to the special game. A special game is a game that has a higher possibility of acquiring more medals than the number of medals that can be acquired in a normal game, and is a game that is advantageous to the player. In general, the special combination includes a BB combination (Big Bonus) and an RB combination (Regular Bonus). These BB combination or RB combination is a combination to shift to BB game or RB game, which is one of special games.

  The small combination is a combination in which a predetermined number of medals are paid out. As described above, there are a plurality of types of small roles such as a watermelon role, a bell role, and a cherry role. When a small combination is drawn by lottery processing, one type of small combination is determined. The number of medals to be paid out is preset in accordance with the type of the small role.

  Furthermore, the re-game player can play the current game while maintaining the number of medals inserted in the previous game (the number of bets), that is, a player who can play the game again. is there.

  The role lottery means 120 includes, for example, a random number generation means 122, a random number extraction means 124, and a random number determination means 126. The random number generation means 122 generates a random number for a lottery (such as a hardware random number). The random number extraction unit 124 extracts the random number generated by the random number generation unit 122. The random number determination means 126 determines the presence / absence of a winning combination and the winning combination based on the random number value extracted by the random number extracting means 124. The role lottery means 120 constitutes “lottery means”, and “lottery processing” is performed.

  The “lottery process” is a lottery process for determining whether a game is won or missed. Specifically, it is executed in step S16 of FIG.

<Random number generator 122>
The random number generator 122 continuously generates random numbers in a predetermined positive integer range (for example, 0 to 65535 in decimal notation) at predetermined timings.

<Random number extraction means 124>
The random number extraction unit 124 extracts the random number generated by the random number generation unit 122 at a predetermined timing. For example, in the present embodiment, random numbers are extracted when the start switch 42 is operated by the player.

<Random number judging means 126>
The random number judging unit 126 collates the random number value extracted by the random number extracting unit 124 with a probability table stored in a judgment collation data storage unit (not shown), thereby corresponding to the region to which the random number value belongs. To decide.

  There are a plurality of types of probability tables, for example, a normal game probability table 127 and a special game probability table 128.

  The process of selecting this probability table is executed in step S14 or S15 of FIG.

  It is assumed that “winning” is selected by the role lottery means 120 when the above-mentioned role lottery means 120 wins the BB role, the RB role, the bell role, the watermelon role, the cherry role, or the replaying role. Further, it is assumed that when the lottery process results in a winning that is not the above-mentioned winning combination, “losing” is selected by the winning lottery means 120.

<Normal game probability table 127>
The normal game probability table 127 (one determination collation data) is selected and referred to when a lottery process is performed when a normal game is being performed. The normal game probability table 127 is preferably stored in the ROM of the main control board 32 described above.

  For example, as shown in FIG. 5 (a), the normal game probability table 127 is obtained by dividing an integer in a range of 0 to 65535 into a plurality of areas, and each of the areas is associated with a type of role. . The method of dividing the area may be based on the type of combination. For example, the area may be divided by finely classifying for each type of combination, or may be divided and classified for each characteristic of the combination.

  Specifically, when the region of the normal game probability table 127 is divided for each type of role, including a disengagement, a bell role, a watermelon role, a replay role (replay role), a BB role, and an RB role It can be divided into six regions. Further, the bell role and the watermelon role can be classified as a small role as the nature of the role, and the BB role and the RB role can be classified as a special role as the nature of the role. Therefore, when the area of the normal game probability table 127 is divided according to the character of the combination, it can be divided into four areas including a re-playing combination, a small combination, and a special combination, including a deviation.

  In the following, as shown in FIG. 5 (a), there are six areas when divided according to the type of combination, a bell combination area R1 (a), a watermelon combination area R2 (a), and a re-game combination area R3. (A), BB combination region R4 (a), RB combination region R5 (a) and out-of-range region R6 (a) will be described.

  In FIG. 5A, the small role region (R1 (a) and R2 (a)), the re-playing role region R3 (a), and the special role region (R4 (a) and R5 (a)). The boundaries of the four areas of the out-of-range area R6 (a) are indicated by solid lines, and the names of the respective roles are indicated without parentheses. In addition, the boundary between the bell role and the watermelon role, which are small roles, is indicated by a broken line, and the name of each role is indicated by parentheses. Furthermore, the boundary of the area of the special combination BB combination and RB combination is indicated by a broken line, and the name of each combination is indicated by parentheses.

  The bell role area R1 (a) is an area for determining that the bell role is won when a random number belonging to this area is issued. The watermelon combination area R2 (a) is an area for determining that the watermelon combination is won when a random number belonging to this area is issued. The re-gamer area R3 (a) is an area for determining that a re-gamer is won when a random number belonging to this area is issued. The BB combination area R4 (a) is an area for determining that the BB combination is won when a random number belonging to this area is issued. The RB combination area R5 (a) is an area for determining that the RB combination is won when a random number belonging to this area is issued. The out-of-range area R6 (a) is an area for determining that the area is out when a random number belonging to this area is issued.

  Bell role region R1 (a), watermelon role region R2 (a), re-playing role region R3 (a), BB role region R4 (a), RB role region R5 (a) and out-of-range region R6 Each of the six regions in (a) is defined by an upper limit value and a lower limit value.

  That is, the bell role region R1 (a) is defined by the lower limit value MIN1 (a) and the upper limit value MAX1 (a), and the size of the bell role region R1 (a) is equal to the lower limit value MIN1 (a). It is determined by the difference from the upper limit value MAX1 (a). Here, the lower limit value MIN1 (a) of the bell role region R1 (a) is equal to the lower limit value of the normal game probability table 127, and the value is an integer 0.

  The watermelon role region R2 (a) is defined by the lower limit value MIN2 (a) and the upper limit value MAX2 (a), and the size of the watermelon role region R2 (a) is smaller than the lower limit value MIN2 (a) and the upper limit value. It is determined by the difference from MAX2 (a).

  The re-gamer area R3 (a) is defined by a lower limit value MIN3 (a) and an upper-limit value MAX3 (a), and the size of the re-gamer area R3 (a) is lower than the lower limit value MIN3 (a). It is determined by the difference from the upper limit value MAX3 (a).

  The BB combination region R4 (a) is defined by the lower limit value MIN4 (a) and the upper limit value MAX4 (a), and the size of the BB combination region R4 (a) is lower than the lower limit value MIN4 (a) and the upper limit value. It is determined by the difference from MAX4 (a).

  The RB combination region R5 (a) is defined by the lower limit value MIN5 (a) and the upper limit value MAX5 (a), and the size of the RB combination region R5 (a) is lower limit value MIN5 (a) and the upper limit value. It is determined by the difference from MAX5 (a).

  The outlier region R6 (a) is defined by the lower limit value MIN6 (a) and the upper limit value MAX6 (a), and the size of the outlier region R6 (a) is lower limit value MIN6 (a) and upper limit value MAX6 ( It is determined by the difference from a). Here, the upper limit value MAX6 (a) of the outlying area R6 (a) is equal to the upper limit value of the normal game probability table 127, and its value is an integer 65535.

  In the normal game probability table 127, it is determined that the upper limit value and the lower limit value of two adjacent areas are different. That is, at the boundary between two adjacent regions, the upper limit value and the lower limit value are determined so that the upper limit value of one region is larger than the lower limit value of the other region. Specifically, the upper limit value MAX1 (a) of the bell role region R1 (a) and the lower limit value MIN2 (a) of the watermelon region R2 (a) are determined to be different, and the watermelon role region R2 ( The upper limit value MAX2 (a) of a) and the lower limit value MIN3 (a) of the re-gamer area R3 (a) are determined to be different, and the upper limit value MAX3 (a) of the re-gamer area R3 (a) ) And the lower limit value MIN4 (a) of the BB combination region R4 (a), the upper limit value MAX4 (a) of the BB combination region R4 (a) and the RB combination region R5 (a) ) Is set to be different from the lower limit value MIN5 (a), and the upper limit value MAX5 (a) of the RB combination region R5 (a) is different from the lower limit value MIN6 (a) of the outlying region R6 (a). It is prescribed as follows.

  By determining in this way, the normal game probability table 127 includes the bell role area R1 (a), the watermelon role area R2 (a), the re-game role area R3 (a), and the BB role area R4 (a). ), The six regions of the RB combination region R5 (a) and the outlying region R6 (a) can be determined so as not to overlap each other.

  The normal game probability table 127 corresponds to “one determination collation data”, the above-mentioned watermelon role region R2 (a) corresponds to “one region”, and the bell role region R1 (a) corresponds to “others”. Corresponds to “region of”. In the example described above, the bell role region R1 (a), the watermelon role region R2 (a), the re-game role region R3 (a), the BB role region R4 (a), the RB role region R5 ( It is determined that none of the six regions a) and the outlying region R6 (a) overlap with each other. However, the region R2 (a) serving as a watermelon that is “one region” and the “other region” What is necessary is just to determine so that the area | region R1 (a) of a certain bell combination may not mutually overlap.

<Special game probability table 128>
The special game probability table (other determination verification data) 128 is selected and referred to when a lottery process is performed when a special game is being performed. The special game probability table 128 is preferably stored in the ROM of the main control board 32 described above.

  An example of the special game probability table 128 is shown in FIG. In the example shown in FIG. 5 (b), there are only two regions, a small role bell role region R1 (b) and a watermelon role region R2 (b). In FIG. 5B, the boundary between the bell role region R1 (b) and the watermelon role region R2 (b) is indicated by a broken line.

  The bell role area R1 (b) is an area for determining that a bell role is won when a random number belonging to this area is issued. The watermelon role region R2 (b) is a region for determining that a watermelon role has been won when a random number belonging to this region is issued.

  In the special game probability table 128, the bell role region R1 (b) and the watermelon role region R2 (b) are defined by an upper limit value and a lower limit value.

  That is, the bell role region R1 (b) of the special game probability table 128 is defined by the lower limit value MIN1 (b) and the upper limit value MAX1 (b), and the size of the bell role region R1 (b) is It is determined by the difference between the lower limit value MIN1 (b) and the upper limit value MAX1 (b). Here, the lower limit value MIN1 (b) of the bell role region R1 (b) is equal to the lower limit value of the special game probability table 128, and its value is an integer 0. The upper limit value MAX1 (b) of the bell combination region R1 (b) is equal to the upper limit value of the special game probability table 128, and the value is an integer 65535.

  The watermelon role region R2 (b) of the special game probability table 128 is defined by a lower limit value MIN2 (b) and an upper limit value MAX2 (b), and the size of the watermelon role region R2 (b) is lower limit value. It is determined by the difference between MIN2 (b) and the upper limit value MAX2 (b).

  The above-mentioned special game probability table 128 corresponds to “other judgment matching data”, the watermelon role region R2 (b) corresponds to “one region”, and the bell role region R1 (b) corresponds to “others”. Corresponds to “region of”.

  As shown in FIG. 5B, in the special game probability table 128, the lower limit value MIN1 (b) of the bell role area R1 (b) is equal to the lower limit value of the special game probability table 128 and the upper limit value. The value MAX1 (b) is equal to the upper limit value of the special game probability table 128. By doing so, the bell combination region R1 (b) corresponding to “other region” is defined throughout the special game probability table 128 which is “other determination collation data”.

  As a result, as shown in FIGS. 5A and 5B, the size of the bell role area R1 (a) of the normal game probability table 127 and the bell role of the special game probability table 128 are increased. The size of the region R1 (b) can be different.

  The lower limit value MIN2 (a) of the watermelon role region R2 (a) of the normal game probability table 127 and the lower limit value MIN2 (b) of the watermelon role region R2 (b) of the special game probability table 128 are as follows. The upper limit value MAX2 (a) of the watermelon role region R2 (a) of the normal game probability table 127 and the upper limit value MAX2 (b) of the watermelon role region R2 (b) of the special game probability table 128 are the same. Is the same. Accordingly, the size of the watermelon role region R2 (a) of the normal game probability table 127 and the size of the watermelon role region R2 (b) of the special game probability table 128 are the same, and their positions are also the same. is there.

  With this configuration, in the special game probability table 128, a region where the bell role region R1 (b) and the watermelon role region R2 (b) overlap can be formed. When the random number value extracted by the random number extraction unit 124 belongs to the overlapped area, the random number determination unit 126 determines that both the bell role and the watermelon role are won at the same time, that is, the bell role and the watermelon role overlap. Judge that it was won.

<Determination verification data selection means 129>
The judgment collation data selection means 129 selects the normal game probability table 127 (one judgment collation data) when a normal game is being performed, and when the special game is being performed, the special game probability table 128 ( Other decision verification data) is selected.

  This process is executed in steps S13 to S15 in FIG.

<Reel drive control means 130>
The reel drive control means 130 performs rotation control and stop control of the three reels 30L to 30R based on the start signal issued from the start switch 42 and the end signal issued from the stop switches 44a to 44c. . The reel drive control unit 130 includes a reel rotation control unit 132 and a reel stop control unit 134. The reel drive control means 130 constitutes “reel drive control means”.

<Reel rotation control means 132>
The reel rotation control means 132 issues a rotation control signal to the motors 86a, 86b and 86c when it detects a start signal issued from the operation means 500, preferably the start switch 42 described above. As will be described later, the motor 86a drives the left reel 30L, the motor 86b drives the middle reel 30C, and the motor 86c drives the right reel 30R. When the reel rotation control means 132 detects the start signal, it issues a rotation control signal to these three motors 86a, 86b and 86c. With the rotation control signal, the three reels 30L to 30R start to rotate. This process is executed in step S17 of a subroutine shown in FIG.

<Reel stop control means 134>
The reel stop control means 134 issues a stop control signal to the motor 86a, 86b or 86c when it detects an end signal issued from the operation means 500 described above, preferably from the stop switches 44a to 44c. As described above, the left reel 30L corresponds to the stop switch 44a, the middle reel 30C corresponds to the stop switch 44b, and the right reel 30R corresponds to the stop switch 44c. That is, when an end signal is issued from the stop switch 44a, the reel stop control means 134 issues a stop control signal to the motor 86a that drives the left reel 30L to stop the left reel 30L. When an end signal is issued from the stop switch 44b, a stop control signal is issued to the motor 86b that drives the middle reel 30C to stop the middle reel 30C. Further, when an end signal is issued from the stop switch 44c, a stop control signal is issued to the motor 86c that drives the right reel 30R to stop the right reel 30R. These processes are executed in step S18 of a subroutine shown in FIG.

  The reel stop control means 134 is configured such that when the above-described random number determination means 126 refers to a game probability table (not shown) based on the random number value and the winning combination is determined, the winning combination is won. Then, stop control of the three reels 30L, 30C and 30R is performed.

  Further, when the special game probability table 128 shown in FIG. 5B is selected and both the watermelon role and the bell role are selected, the three reels so that the watermelon role or the bell role is won. Stop control of 30L, 30C and 30R is performed. That is, stop control is performed so that the watermelon symbols are aligned on the effective lines L1 to L5 or the bell symbols are aligned. Specifically, the stop control is performed so that both the watermelon role and the bell role are so-called tempering, and when it is determined that the tempering cannot be performed, either the watermelon role or the bell role is given priority. Control to stop. The “tempe” means a state in which up to two fixed symbols can be aligned on a certain effective line by the reel stop control. Therefore, if both the watermelon role and the bell role are tempered, up to two watermelon symbols can be aligned on one effective line, and up to two bell symbols can be aligned on the other effective line. The state that was able to.

  In particular, when a plurality of bell symbols are arranged on the three reels 30L, 30C and 30R within a predetermined interval, for example, within an interval corresponding to the moving distance from the start of stop control of the reels 30L to 30R to the stop. The reels 30L to 30R are controlled to stop so that the winning of the bell role is given priority when both the watermelon role and the bell role cannot be tempered. Like that. In this way, when both the watermelon role and the bell role are won, it is possible to stop control so that at least the bell role wins. By such arrangement of symbols and reel stop control, it is possible to always win some role, that is, to eliminate so-called missing.

<Design detecting means 150>
The symbol detection means 150 detects a symbol that reaches or can reach a certain rotation reference position based on the end signal issued from the operation means 500. That is, in response to the player operating the operation unit 500, the reel drive control unit 130 starts stop control of the left reel 30L, the middle reel 30C, or the right reel 30R. The symbol detection means 150 detects a symbol that may stop at a certain rotation reference position when controlling the reels 30L to 30R by detecting the symbol located at the certain rotation reference position described above. That is, it is possible to detect a symbol that has reached or can reach a certain rotation reference position.

  Even if the reel 30L, 30C or 30R is stopped immediately, even if it is immediately braked, it takes a predetermined time to stop. May not be able to stop at the rotation reference position. That is, even in the case of “a symbol reaching a certain rotation reference position”, the reel may not be stopped so that the symbol is located at a certain rotation reference position. In such a case, the reel stop control means 134 described above controls stop of the reels 30L, 30C, or 30R so that “a symbol that can reach a certain rotation reference position” is located at a certain rotation reference position.

  Here, detecting a symbol specifically means obtaining a symbol number of a stop control table (not shown) stored in advance. The stop control table stores a symbol number and stop information for symbols attached to each of the three reels of the left reel 30L, the middle reel 30C, and the right reel 30R. The symbol number is a numerical value indicating the position of the symbol arrangement on the reel, and is a numerical value indicating the position from the reel reference position along the circumferential direction of the reel, with a certain position on the reel as the reel reference position. The stop information is information used to stop the reels 30L to 30R, and the reels 30L to 30L are positioned so as to be positioned at a fixed reference position in the rotation direction of the reels, for example, on the winning line L3. This is information used to stop-control 30R.

  In addition, the symbol detection means 150 detects the type of symbols stopped on the active line for the reels that have already stopped. The symbol “stopped” on this active line means that, in principle, the effective line is located at the approximate center of the symbol, but when the reel stops, the correspondence between the active line and the symbol is played. If the person can be recognized, the positional relationship is not limited to this.

  As will be described later, the rotation angle sensors 83a to 83c generate signals corresponding to the angles at which the reels 30L, 30C, and 30R are rotated. The symbol number can be obtained based on this signal. Furthermore, the symbol detection means 150 stores a symbol correspondence table (not shown) that defines the correspondence between symbol numbers and symbol types corresponding to symbol numbers. By obtaining a symbol number based on the signals generated from the rotation angle sensors 83a to 83c and searching the symbol correspondence table, the type of symbol corresponding to the symbol number can be obtained.

  The symbol detection by the symbol detection means 150 is executed when the reel stop control process in step S18 in FIG. 4 is performed.

<Design display means 400>
The symbol display means 400 includes reels 30L, 30C and 30R. On each of the reels 30L, 30C, and 30R, a predetermined number, for example, 21 symbols are arranged along the rotation direction of the reel.

  The reel 30L includes a motor 86a for rotating the reel 30L and a rotation angle sensor 83a for detecting the rotation angle of the reel 30L. The reel 30C includes a motor 86b for rotationally driving the reel 30C and a rotation angle sensor 83b for detecting the rotation angle of the reel 30C. The reel 30R includes a motor 86c for rotationally driving the reel 30R and a rotation angle sensor 83c for detecting the rotation angle of the reel 30R.

  The rotation angle sensors 83a to 83c emit signals corresponding to the angles at which the reels 30L, 30C, and 30R are rotated. When the reels 30L to 30R are at a predetermined rotational position in the rotation direction, the rotation angle sensors 83a to 83c generate signals corresponding to the angles rotated from the origin. For example, the reels 30L, 30C, and 30R are divided into one rotation, that is, 360 degrees, equally divided into 400 steps. In this case, the rotation angle sensors 83a to 83c emit signals indicating steps from 0 to 399 according to the angles at which the reels 30L, 30C, and 30R are rotated. Specifically, when the reels 30L to 30R are located at the origin, a signal indicating the 0th step is issued, and when the reels 30L to 30R are at a rotational position rotated by 90 degrees from the origin, a signal indicating the 99th step. To emit. In this way, it is possible to obtain how much the reels 30L to 30R are rotated from the origin based on the signals generated from the rotation angle sensors 83a to 83c. The above description is for conceptually explaining the signals emitted from the rotation angle sensors 83a to 83c. In the slot machine 10, the rotation angle sensors 83a to 83r are used to obtain the positions of the reels 30L to 30R. Instead of detecting a signal emitted from 83c, detection is performed in order to obtain a symbol number or a symbol type or to specify a predetermined symbol position, as will be described later.

  As described above, the symbol detection means 150 stores a symbol correspondence table (not shown) that defines the correspondence between symbol numbers and symbol types corresponding to symbol numbers. Here, for example, when 21 symbols are attached to one reel along the circumferential direction, the symbol number is set to a reel reference position with a certain position on the reels 30L to 30R as a reel reference position. The arranged symbol is the symbol in frame 0. The first frame design, the second frame design,... In this order along the circumferential direction with reference to this origin, and the last 21st design as the 20th frame design. The symbol correspondence table stored in the symbol detection means 150 stores the correspondence between this symbol number and the symbol type corresponding to this symbol number. For example, for the left reel 30L, the symbol correspondence table shows that the 0th frame is the symbol “Plum”, the 8th frame is the symbol “Replay”, and the 16th frame is the symbol “Blue cherry”. Remember.

  By adopting such a configuration, it is possible to search the symbol correspondence table based on signals emitted from the rotation angle sensors 83a to 83c and acquire the symbol type. For example, the symbol number of the reel 30L at the position of the winning line L3 is obtained based on the signal generated from the rotation angle sensor 83a, and the type of the symbol positioned at the winning line L3 can be obtained from the symbol number. . By doing in this way, regardless of whether the reels 30L to 30R are rotating or stopped, the types of symbols positioned on the effective lines L1 to L5 and the effective lines L1 to L5 It is possible to identify the types of symbols that can be stopped.

<< Control processing >>
Below, the control performed in the main control means 100 (main control board 32) mentioned above is demonstrated. FIG. 4 is a subroutine for executing control processing in the main control means 100.

  In the following, the slot machine 10 is started in advance, and in the main control unit 100 described above, after starting processing such as initialization of various variables used for control, the slot machine 10 operates normally. It shall be. Further, the flowchart shown in FIG. 4 shows only one example for executing the control processing in the main control means 100, and is not limited to this processing procedure.

<Control in main control means 100>
FIG. 4 is a flowchart showing control in the main control means 100.

  Based on the signal generated by the player operating the 1-bet switch 62, 2-bet switch 64 or maximum bet switch 66 described above, the number of inserted sheets is determined (step S11). This inserted number indicates the number of medals targeted for betting for one game, and is not only the number of medals targeted for betting after being temporarily accumulated as the number of credits described above, It also includes the number of medals that have been inserted through the medal insertion slot 46 and are directly bet.

  Next, it is determined whether or not the start switch 42 has been operated by the player (step S12). When it is determined that the start switch 42 is not operated, the process of step S12 is repeated.

On the other hand, when it is determined that the start switch 42 has been operated, it is determined whether or not a special game is being performed (step S13). When it is determined that a special game is not being performed, the normal game probability table 127 is selected (step S14), and when it is determined that a special game is being performed, the special game probability table 128 is selected (step S15). ).
After executing the process of step S14 or S15, a lottery process is executed using the selected probability table (step S16).
Next, rotation control of the three reels 30L, 30C, and 30R is started (step S17). Next, stop control of the three reels 30L, 30C and 30R is executed (step S18), a winning process is executed (step S19), and this subroutine is finished.
