Description

  The present invention relates to a slot machine in which a plurality of winning combinations may be won by lottery processing.

Traditionally, there have been slot machines that allow multiple types of small roles to be won. In this conventional slot machine, since it was a small role that won a duplicate, only the number of medals that a player can obtain was different (see, for example, Patent Document 1).
JP 2004-222873 A

  As described above, in the conventional slot machine, the small role is elected repeatedly, so even if it is won, the profit given to the player is not greatly changed, and the player's expectation is increased. It wasn't.

  The present invention has been made in view of the above-mentioned points. The purpose of the present invention is to allow a player to win a plurality of winning combinations and to make different types of winning combinations that can be won simultaneously. It is an object of the present invention to provide a slot machine that can change the benefits to be given and can increase the player's expectation.

  In order to achieve the above object, in the present invention, the first determination collation data and the second determination collation data are determined so that at least two determination areas overlap, and the first determination collation data The type of at least one combination determined by the overlapping determination area is different from any of the combinations determined by the overlapping determination area of the second determination verification 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
Including a lottery means for drawing the types of roles, and
The role lottery means
A random number generating means for generating a random number;
Random number judging means for storing a plurality of judgment collation data for judging the type of the combination based on the value of the random number, each of the plurality of judgment collation data comprising a plurality of judgment areas, and Each of the plurality of determination areas is delimited by an upper limit value and a lower limit value, and the type of the combination is determined according to a determination area to which the random number value belongs among the plurality of determination areas. Random number judging means for performing, and
Of the plurality of determination verification data, the first determination verification data and the second determination verification data are defined by overlapping at least two determination areas, and
The random number determination means determines that at least two types of roles have been won when one random number value belongs to a determination region where the first determination verification data or the second determination verification data overlaps; and
The type of at least one of the first plurality of types determined by the overlapping determination area of the first determination collation data is determined by the overlapping determination area of the second determination collation data. It is different from any of the second plurality of types of roles.

  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. For example, when four pieces of determination matching data are stored in the random number determination means, the first determination matching data is used in the normal game, and the second determination matching data is used in the first replay high-probability game. The third determination matching data can be used in the third replay high probability game, and the fourth determination matching data can be used in the fourth replay high probability game.

  Each of the plurality of determination collation data includes a plurality of determination areas. For example, the first determination matching data can be configured to include eight determination areas, and the second determination verification data can be configured to include nine determination areas. As shown in this example, it is only necessary that each of the plurality of determination collation data includes a plurality of determination areas, and the number of determination areas does not have to be the same for all of the plurality of determination collation data.

  The method of configuring the plurality of determination areas 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. For example, in the case where the type of role consists of five types of a bell role, a watermelon role, a re-playing role, a BB role and an RB role, the first determination area is divided into six determination areas, and the first determination area is for the bell role, The second determination area is the watermelon combination, the third determination area is the re-game combination area, the fourth determination area is the BB combination area, the fifth determination area is the RB combination area, and the sixth determination area Is defined as an outlier region.

  Note that, as will be described later, the BB combination is a combination of shifting to the BB game, which is one of the special games advantageous to the player. The RB combination is a combination of shifting to the RB game, which is one of the special games advantageous to the player. The bell role and the watermelon role are roles for paying out a predetermined number of game media. It is a role that gives a profit that allows a new game to be started without making an investment by introducing a game medium. Also, an outage does not give any benefit to the player.

  In addition, the above-mentioned bell role and watermelon role can be classified as a small role as the nature of the role, and the BB role and RB role can be classified as a special role as the nature of the role. Thus, when classified according to the nature of the combination, it can be classified into three types: small combination, replay combination, and special combination. In this case, the first determination area is divided into four determination areas, the second determination area is the re-game combination area, the third determination area is the special combination area, The judgment area is set as an outlier area.

  Each of the plurality of determination areas in each of the plurality of determination collation data is delimited by an upper limit value and a lower limit value. That is, in each of the plurality of determination regions, the upper limit of the determination region is defined by the upper limit value, and the lower limit of the determination 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 determination areas the random number value generated by the random number generation means belongs. As described above, since the plurality of determination areas are determined based on the type of the combination, the type of the combination can be determined by the area to which the random number value belongs.

  For example, when the combination consists of three types of special combination, small combination, and replay combination, as described above, the first determination area is divided into four determination areas, the first determination area is divided into the small combination area, the second combination The determination area is defined as a re-game area, the third determination area is defined as a special role area, and the fourth determination area is defined as an outlier area.

  In the case of this example, when the value of the random number generated by the random number generation means belongs to the first determination area, it is determined as a small combination. When the random number value belongs to the second determination area, it is determined as a re-playing combination, and when the random number value belongs to the third determination area, it is determined as a special combination. Furthermore, when the value of the random number belongs to the fourth determination area, it is determined that it is out of place.

  The plurality of determination verification data includes at least “first determination verification data” and “second determination verification data”. Each of these “first determination verification data” and “second determination verification data” includes a plurality of determination areas as described above. Note that, as described above, each of the “first determination collation data” and the “second determination collation data” may include a plurality of determination areas, and the determination areas of the “first determination collation data” The number and the number of determination areas of the “second determination collation data” do not have to be the same. For example, the “first determination / collation data” may be configured by eight determination areas, and the “second determination / collation data” may be configured by nine determination areas.

  At least two or more determination areas of the plurality of determination areas of these “first determination verification data” and “second determination verification data” are determined to overlap each other. For example, when the “first determination collation data” includes eight determination areas from the first determination area to the eighth determination area, the third determination area and the fourth determination area overlap. Can be configured. Moreover, you may comprise so that three or more determination area | regions may overlap. For example, when the “first determination collation data” includes eight determination areas, the third determination area, the fifth determination area, and the sixth determination area may overlap each other. Similarly, the “second determination collation data” is configured such that at least two or more determination areas overlap each other.

  The random number determination means determines that at least two or more types of winning combinations are won when one random number value belongs to a determination region where the first determination verification data or the second determination verification data overlaps. That is, it is determined that two or more types corresponding to the overlapped determination area are overlapped.

  For example, the determination region of the first determination collation data is divided into six, the first determination region is the bell role region, the second determination region is the watermelon role region, and the third determination region is the re-game role. Area, the fourth determination area is the BB combination area, the fifth determination area is the RB combination area, and the sixth determination area is an outlier area, and the second determination area and the fifth determination area overlap. In the case of such a configuration, when a random number value belongs to an overlapping determination area, it is assumed that the watermelon combination and the RB combination are won in duplicate.

  The type of at least one of the first plurality of types determined by the overlapping determination area of the first determination verification data is determined by the determination area of the second determination verification data overlapping. It is different from any of the two types of roles.

  As described above, when a random number value belongs to an overlapped determination area, it is determined that two or more winning combinations corresponding to the area are overlapped. When the first determination / collation data is selected, two or more types of combinations determined by the random number value belonging to the overlapping determination area of the first determination / collation data are indicated as “first plural types”. ” In addition, when the second determination / collation data is selected and the random number value belongs to the determination area where the second determination / collation data overlaps, two or more roles corresponding to the overlap area are duplicated. It is determined that Two or more types of winning combinations determined by the fact that random value values belong to the overlapping determination areas of the second determination collation data are referred to as “second plural types of winning combinations”.

  The first determination collation data and the second determination collation are such that at least one of the “first plural types of combinations” is different from any of the “second plural types of combinations”. Data is structured.

  For example, if the “first plurality of types of roles” are a BB role and a watermelon role, and the “second plurality of types of roles” are a BB role and a bell role, the BB role is “ The common combination of the “first plurality of types of combination” and the “second plurality of types of combination”, but the watermelon combination of the “first plurality of types of combination” is “the second plurality of types” It is different from both the BB role and the Bell role. Therefore, by configuring in this way, it is possible to make “at least one of the first plurality of types of combinations different from any of the second plurality of types of combinations”.

  As described above, the “at least one combination type” of the first plurality of types of combinations may be different from any of the second plurality of types of combinations. For example, the first plurality of types of roles are three roles of BB role, RB role and watermelon role, and the second plurality of types of roles are three roles of BB role, RB role and Bell role. In the case of a combination, the BB combination and the RB combination are common to the first plurality of types of combination and the second plurality of types of combination, but the watermelon of the first plurality of types of combination Since the combination is different from any of the three combinations of the second plurality of types of combinations, the “at least one combination type” of the first plurality of types of combinations is the second plurality of types of combinations. It will be different from any of the above.

  As described above, even when the number of “first plural types of roles” and the number of “second multiple types of roles” are three or more, of the first plural types of roles The “at least one role type” may be configured to be different from any of the second plurality of types of roles.

  By doing as described above, by selecting either “first determination collation data” or “second determination collation data”, it is determined whether or not a combination has been won. When the winning combination is won, the “at least one kind of combination” of the first plurality of types is different from any of the second plurality of types. The profit given to the player can be changed between when the data is won in duplicate and when the data is won in the second determination matching data, and the player's expectation may be increased.

The types of roles include a plurality of types of special roles for shifting to a special game advantageous to the player, and a plurality of types of small roles for paying out game media, and
Each of the first plurality of types of combinations and the second plurality of types of combinations includes both the special combination and the small combination,
The types of special roles included in the first plurality of types of roles match the types of special roles included in the second plurality of types of roles; and
It is preferable that the types of small combinations included in the first plurality of types of combinations differ from the types of small combinations included in the second plurality of types of combinations.

  The types of roles include at least a plurality of types of special roles and a plurality of types of small roles. This special role is a role for shifting to a special game that is advantageous to the player. A small role is a role for paying out game media. Special roles consist of multiple types, and small roles also consist of multiple types. For example, the special combination can be made up of two types, a BB combination and an RB combination. Also, the small role can be made up of three types: a bell role, a watermelon role, and a cherry role.

  The above-mentioned “first plurality of types of roles” include both a plurality of types of special roles and a plurality of types of small roles, and also the above-mentioned “second plurality of types of roles”. Both a plurality of types of special roles and a plurality of types of small roles are included.

  The type of special combination included in the “first plurality of types of combination” matches the type of special combination included in the type of “second plurality of types of combination”. That is, the types and numbers of the combinations of the plurality of types of special roles of the “first plurality of types of combinations” and the types of special combinations of the “second plurality of types of combinations” are the same. means. For example, when the special role of “first multiple types of roles” consists of two roles of BB role and RB role, the special roles of “second multiple types of roles” are also BB role and RB This means that it consists of two roles.

  The types of small roles included in the “first plurality of types of roles” are different from the types of small roles included in the “second plurality of types of roles. That is,“ first multiple types of roles. The plurality of types of small roles and the plurality of types of small roles of “the second plurality of types” means that the types and numbers of the roles are different. Note that all of the multiple types of small roles in the “first multiple types of roles” do not have to be different from the multiple types of small roles in the “second multiple types of roles”, and some of them must be different. That's fine. For example, when the small role of “first plural types of roles” consists of two types of roles of bell and watermelon, the small role of “second multiple types of roles” It only has to be made up of two types, the role of cherry. The bell role is common to the “first multiple types of roles” and the “second multiple types of roles”, but the “first multiple types of roles” watermelon role This is because it is different from the small combination of “first plural types of combination”.

  If the winning combination is duplicated, the special combination and the small combination are selected and the special combination and the small combination are selected, depending on whether the “first determination verification data” or the “second determination verification data” is selected. You can change the type of small role. In addition, when the small role can be won, it can give a sense of expectation that the special role will also be won by overlapping and winning, and with the “first determination verification data”, Since the types of small roles to be won in duplicate can be made different from the “second determination / collation data”, it is possible to increase opportunities for giving a sense of expectation.

  In addition, in the case of including notification means that can be recognized by the player, for example, image display means, voice output means, etc., when the winning is duplicated, the effect that gives the expectation that it will shift to a special game is won. Since it can be performed for each kind of small role, the range of production of expectation can be expanded. Furthermore, even when a small role that can be won in duplicate is won alone, by performing for each type of the small role, the range of the effect of expectation can be further expanded.

Based on the lottery result by the combination lottery means, game control means for selecting and playing either a normal game or a plurality of advantageous games that are more advantageous to the player than the normal game;
Determination collation data selection for selecting the first judgment collation data or the second judgment collation data in correspondence with the plurality of advantageous games based on the display mode of the symbols when the plurality of reels are stopped And a means is desirable.

  The game control means selects one of the normal game and a plurality of advantageous games. This selection is performed based on the lottery result by the combination lottery means. There are a plurality of advantageous games, and any of them is a game that can be advantageous to the player over the normal game.

  The judgment collation data selection means selects the first judgment collation data or the second judgment collation data based on the display mode of the symbols when a plurality of reels are stopped. The first determination verification data or the second determination verification data is determined so as to correspond to a plurality of advantageous games. For example, in the case of the first advantageous game, the first determination / collation data is selected, and in the case of the second advantageous game, the second determination / collation data is selected. In this example, when the first advantageous game is performed, the first determination / collation data is selected and the lottery process is performed, and when the second advantageous game is performed, the second determination / collation data is stored. A lottery process is performed upon selection.

  By doing so, it is possible to change the profits given to the player by making the multiple winning combinations overlap and different types of winning combinations depending on the advantageous game, Expectation can be raised. In addition, in the case of including notification means that can be recognized by the player, for example, image display means, voice output means, etc., there is a range of effects that gives a sense of expectation that the game will shift to a special game in accordance with the advantageous game. Can be spread.

  By making a plurality of winning combinations overlapping and making different types of winning combinations that can be won simultaneously, it is possible to change the profits given to the player and raise the player's expectation.

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

  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.

<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.

  Further, when the special game is finished or when the three reels 30L to 30R are stopped and the combination of symbols aligned on the effective line becomes a predetermined one, the replay high probability game is performed. This replay high-probability game is a game that is performed with the probability of winning a re-gamer being higher than the predetermined probability of winning a re-gamer when a normal game is being played, which is advantageous to the player. It is a possible 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.

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 S14 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 replay high probability game probability table 128.

  The process of selecting this probability table is executed in step S13 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 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 detachment, a cherry role, a BB role, a watermelon role, a bell role, an RB role, and a replaying role (replay) Can be divided into seven areas. In addition, the bell role, the watermelon role, and the cherry 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 seven regions when divided according to the type of the combination, a region R1 (a) for the cherry combination, a region R2 (a) for the BB combination, and a region R3 (for the watermelon combination). Description will be made using a), a bell role region R4 (a), an RB role region R5 (a), a re-playing role (replay role) region R6 (a), and a disengagement region R7 (a).

  The cherry role area R1 (a) is an area for determining that the cherry role is won when a random number belonging to this area is issued. The BB combination area R2 (a) is an area for determining that the BB combination is won when a random number belonging to this area is issued. The watermelon combination area R3 (a) is an area for determining that the watermelon combination is won when a random number belonging to this area is issued. The bell role region R4 (a) is a region for determining that the bell role is won when a random number belonging to this region 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 re-gamer area R6 (a) is an area for determining that a re-gamer is won when a random number belonging to this area is issued. The out-of-range area R7 (a) is an area for determining that the area is out when a random number belonging to this area is issued.

  The seven areas described above, the cherry role area R1 (a), the BB role area R2 (a), the watermelon role area R3 (a), the bell role area R4 (a), and the RB role area R5 (a).

Here, the upper limit value MAX7 (a) of the outlying area R7 (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 cherry role area R1 (a) is set different from the lower limit value MIN2 (a) of the BB role area R2 (a). The upper limit value MAX2 (a) of the BB combination region R2 (a) and the lower limit value MIN3 (a) of the watermelon combination region R3 (a) are determined to be different.

As a result, in the RT2 determination collation data 128b, a part of the BB combination area overlaps with a part of the watermelon combination area, and a part of the RB combination area is the remaining part of the watermelon combination area. And overlap.

  In the RT3 determination collation data 128c, as shown in FIG. 5D, the upper limit value MAX2 (d) of the BB role area is larger than the lower limit value MIN4 (d) of the bell role area, and the bell role area. The upper limit value MAX4 (d) is greater than the lower limit value MIN5 (d) of the RB combination area. As a result, in the RT3 determination collation data 128c, a part of the BB combination area overlaps with a part of the Bell combination area, and a part of the RB combination area is the remaining part of the Bell combination area. And overlap.

  By doing in this way, it is possible to configure at least two or more determination areas to overlap each other in the RT1 determination collation data 128a, the RT2 determination collation data 128b, and the RT3 determination collation data 128c. it can.

  When the random number value extracted by the random number extraction means 124 belongs to the overlapping determination area of the RT1 determination collation data 128a, the RT2 determination collation data 128b, or the RT3 determination collation data 128c, it corresponds to the overlapping determination area. It is determined that multiple winning combinations are won. For example, when the RT1 determination collation data 128a is selected, and the random number value extracted by the random number extraction unit 124 belongs to the area between MIN1 (b) and MAX2 (b), It is determined that the BB role and the Cherry role are won in duplicate. In addition, when the RT3 determination collation data 128c is selected and the random number value extracted by the random number extraction unit 124 belongs to the area between MIN5 (d) and MAX4 (d), It is determined that the winning combination of the RB role and the Bell role is won.

  As shown in FIGS. 5A to 5D, in the RT1 determination collation data 128a, the RT2 determination collation data 128b, and the RT3 determination collation data 128c, the types of small combinations overlapping with the BB combination and the RB combination are as follows. These are the role of cherry, the role of watermelon or the role of bell respectively. Accordingly, at least one of the winning combinations in the RT1 determination collation data 128a is different from either of the winning combinations in the RT2 determination collation data 128b or the RT3 determination collation data 128c.

  By configuring the RT1 determination collation data 128a, the RT2 determination collation data 128b, and the RT3 determination collation data 128c in this manner, at least one of the first plurality of types of roles is the first type. The first determination collation data and the second determination collation data can be configured so as to be different from any of the plurality of types of two combinations.

<Determination verification data selection means 129>
The judgment collation data selection means 129 selects any one of the normal game probability table 127, the RT1 judgment collation data 128a, the RT2 judgment collation data 128b, or the RT3 judgment collation data 128c. This selection is made based on the display mode of the symbols when the reels 30L to 30R are stopped, or when the BB game or RB game, which is a special game, is completed. RT1 decision collation data 128a is selected when the first replay high probability game is performed, and RT2 decision collation data 128b is selected when the second replay high probability game is performed, and RT3 determination collation is performed. The data 128c is selected when the third replay high probability game is performed.

  That is, when the first advantageous game is performed, the RT1 determination collation data 128a is selected and the lottery process is performed, and when the second advantageous game is performed, the RT2 determination collation data 128b is selected and the lottery process. When the third advantageous game is performed, the RT3 determination collation data 128c is selected and a lottery process is performed. When a normal game is played, the normal game probability table 127 is selected and a lottery process is performed.

  This process is executed in step S13 of 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 S15 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 S16 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.

<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 S16 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, a probability table for performing lottery processing by the role lottery means 120 is selected (step S13). Specifically, any one table of the normal game probability table 127, the RT1 judgment collation data 128a, the RT2 judgment collation data 128b, or the RT3 judgment collation data 128c shown in FIGS. 5A to 5D. Select. Selection of these tables is performed based on the result of the unit game performed last time and the game state. For example, when a normal game is being performed, the normal game probability table 127 is selected. When the special game is finished, the RT1 determination collation data 128a is selected. Further, when the three reels 30L to 30R are stopped and the combination of symbols aligned on the effective line becomes a predetermined one, the RT2 determination collation data 128b or the RT3 determination collation data depending on the combination of the symbols. One of 128c is selected.

  After executing the process of step S13, a lottery process is executed using the selected probability table (step S14).

  Next, rotation control of the three reels 30L, 30C, and 30R is started (step S15). Next, stop control of the three reels 30L, 30C and 30R is executed (step S16), a winning process is executed (step S17), and this subroutine is finished.
