Abstract

<P>PROBLEM TO BE SOLVED: To provide a slot machine which enables the diversification of the development in the progress of the games while allowing the further increase of the game media obtainable by the players along with the higher possibility of enhancing the expectations felt for the games by expanding the opportunities of permitting the shift to the special game to other occations not confined to the role lottery. <P>SOLUTION: Two types of special games, first and second, are arranged. The lottery processing to determine whether the shift should be permitted from the normal game to the first special game is carried out up to the operation of the stop switch from the operation of the start switch. The lottery processing to determine whether the shift should be permitted from the normal game to the second special game is conducted before the start switch is operated to start the current game after the lottery processing of the game is done at least once preceding it. At the same time, the lottery probability in the second permission lottery processing is altered from the history information indicating the history of the games. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a slot machine that draws a winning combination by lottery processing and shifts to a special game based on the type of winning combination.

Conventionally, slot machines have been provided with various gaming states that are advantageous to the player. For example, it is possible to shift from a normal game to a plurality of special games such as a big bonus and a regular bonus. When shifting to such a special game, there is a high possibility that the number of game media can be increased, so that the expectation for the game can be increased (for example, see Patent Document 1).
JP-A-10-137389

  As described above, in the conventional slot machine, it is possible to shift to a plurality of special games, but whether or not to shift to these special games is determined by lottery of combinations of symbols in the game, so-called role lottery. It was established. For this reason, the transition to special games was permitted only when the role was won. Furthermore, in many conventional slot machines, the probability of winning a predetermined role by a lottery process is fixed, so the progress of the game has to be poor.

  The present invention has been made in view of the above points, and the purpose of the present invention is to allow the opportunity to shift to a special game not only in the role lottery but also at other occasions. It is intended to provide a slot machine that can increase the expectation of the game, increase the possibility that the player can acquire more game media, and can develop the progress of the game in various ways.

  In order to achieve the above object, in the present invention, there are two types of special games, the first special game and the second special game, from when the start switch is operated until the stop switch is operated. In the meantime, a lottery process is performed to determine whether or not the transition from the normal game to the first special game is permitted, and this game is started after at least one previous game lottery process is performed. Until the start switch is operated, a lottery process is performed to determine whether or not the transition from the normal game to the second special game is permitted, and the second is based on the history information indicating the history of the game. The lottery probability of the permission lottery process is changed.

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
Lottery means for performing extra lottery processing for determining whether or not the game is won or missed;
Reel control means for controlling the rotation of the reel based on an operation of a start switch by a player, and controlling the stop of the reel based on an operation of a stop switch by a player, and ,
Game history storage means for storing history information indicating the history of the game;
The game includes a normal game and a first special game and a second special game that are more advantageous to the player than the normal game,
The extra lottery process includes a first permission lottery process for determining whether or not to permit the transition from the normal game to the first special game, and
The lottery means includes first transition permission lottery means for performing the first permission lottery process as the extra lottery process, and second permission lottery processing for determining whether or not to allow transition from the normal game to the second special game. A second transition permission lottery means for
The first transition permission lottery means includes the first permission lottery from when the start switch is operated to start the current game to when the stop switch is operated to end the current game. Process and
The second transition permit lottery means is operated by the start switch to start the current game after the extra lottery process for the game performed at least one before the current game is performed. The second permit lottery process before being done, and
The second transition permission lottery means includes lottery probability change means for changing a lottery probability of the second permission lottery process based on the history information.

  According to the slot machine of the invention described above, the lottery process for determining whether or not to allow the transition from the normal game to the first special game is performed between the start switch operation and the stop switch operation. This is a role lottery process, and the lottery process for determining whether or not to allow the transition from the normal game to the second special game is performed after the game lottery process performed at least one before is performed. This is done until the start switch is operated to start. As described above, the lottery process for determining whether or not the transition from the normal game to the second special game is permitted is a process separate from the role lottery process, thereby increasing the opportunity for the transition to the special game. The possibility that the expectation to the game can be further increased is generated, and there is a possibility that the game media that can be acquired by the player can be increased.

  Furthermore, since the lottery probability of the second permission lottery process is changed based on the history information indicating the history of the game, the progress of the game to be performed in the future is varied based on the progress of the game that has been performed so far. The possibility of being deployed.

  Here, “history” refers to the progress of things, and “game history” refers to the progress of games that have been played so far. It only needs to indicate the situation and transition. For example, there are the number of times a game has been played, the number of times a prize has been won, the number of game media to be described later, information on the results of lottery processing, and the like.

  In addition, “permission” is different from the actual transfer by determining that the normal game may shift to the first special game or the second special game. That is, the permission is determined separately regardless of whether the normal game is actually shifted to the first special game or the second special game.

  In addition, after the above-mentioned extra lottery process for the game played at least one before the current game is performed, the start switch is operated to start the current game. “Between” means “when the extra lottery process for a game played at least one before the current game is performed” and “when the start switch is operated to start the current game” Means that the second permission lottery process is performed.

  Furthermore, the lottery process for determining whether or not to allow the transition from the normal game to the second special game is performed in order to start the current game after the game lottery process performed at least one time before is performed. It may be performed until the start switch is operated, and even if the lottery process reflecting the result of the game performed at least one time before is independent of the result of the game performed at least one time before A lottery process may be performed.

  Furthermore, in the “game” according to the present invention, the player operates the start switch and the plurality of reels start to rotate until all of the plurality of reels stop as a single-stroke game or unit game. It is a game that can be played. Note that the beginning of a single-stroke game or unit game is when a player operates the start switch and an operation signal is issued from the start switch, even when a plurality of reels can be visually recognized as starting to rotate. Also good. Also, at the end of a single-stroke game or unit game, all of the plurality of reels stop and specify the type of symbol on the active line even when it can be visually recognized that all of the plurality of reels have stopped. It may be when the processing is completed.

  Therefore, the “current game” means a single-stroke game or unit game performed this time. In addition, “a game played at least one time before the current game” means a game of a single game executed at least one time before a single game or unit game played this time. Or it means a unit game.

And a game medium payout means for paying out a predetermined number of game media based on the result of the game, and
The game history storage means stores, as the history information, a difference between a predetermined number of payouts according to a result of the game and an input number inserted to start the game,
Preferably, the lottery probability changing means changes the lottery probability of the second permission lottery process based on the difference.

Since the difference between the number of paid out game media and the number of inserted media is used as history information in this way, the lottery probability is adjusted based on the difference between the number of paid out media media and the number of inserted media so that the so-called play rate is adjusted. And the possibility of changing the development of the game arises.
Here, the “game medium” is a medium to be betted for starting a game, and plays a role as a medium to be paid out according to the result of the game. In addition to coins or the like, it may be a conceptual virtual medium such as variables used for arithmetic processing.

Further, the lottery probability changing means is
A random number generating means for generating a random number;
Collation data storage means for storing a plurality of pieces of collation data for determining whether or not to allow the transition to the second special game based on the value of the random number;
And a selecting unit that selects one of the plurality of pieces of collation data according to the difference.

  In this way, by selecting one verification data from a plurality of verification data according to the difference between the number of paid out and inserted game media, the lottery probability that can shift from the normal game to the second special game is changed. And the progress of the game can be developed in various ways.

Furthermore, it includes a winning number counting means for counting the number of winnings won in a predetermined role corresponding to the winning determined by the extra lottery process,
The game history storage means stores the number of times of winning the predetermined role as the history information,
It is preferable that the lottery probability changing means changes the lottery probability of the second permission lottery process when the predetermined number of winnings reaches the predetermined number.

  By doing so, there is a possibility that the development of the game can be changed by changing the lottery probability based on the number of winning.

In addition, the game history storage means includes a first permission number of times that the first transition permission lottery means permits the transition from the normal game to the first special game, or a second transition permission lottery means that the first transition permission lottery means from the normal game. 2 The second permitted number of times permitted to shift to the special game is stored as the history information,
It is also preferable that the lottery probability changing means changes the lottery probability of the second permission lottery process when the first permission number or the second permission number reaches a predetermined number.

  In this way, there is a possibility that the game development can be changed by changing the lottery probability based on the permitted number of times.

  Furthermore, the lottery process for determining whether or not to allow the transition from the normal game to the second special game is performed in order to start the current game after the game lottery process performed at least one time before is performed. It may be performed until the start switch is operated, and even if the lottery process reflecting the result of the game performed at least one time before is independent of the result of the game performed at least one time before A lottery process may be performed.

And storage means for storing permission / rejection information indicating whether or not to allow transition from the normal game to the second special game.
When the second permission lottery process is performed, it is preferable that permission / non-permission information is stored in the permission / denial information to allow the transition from the normal game to the second special game. Here, the “permission / rejection information” only needs to store information indicating whether or not to permit the transfer, and it is desirable to use a flag whose value is determined by a lottery process.

Furthermore, storage means for storing permission / rejection information indicating whether or not the transition from the normal game to the second special game is permitted,
After the second permission lottery process is performed, at least one game is performed before the permission to shift from the normal game to the second special game is stored in the permission / rejection information Is preferred. By doing in this way, the result of the game played last time can be reflected and the possibility of giving an expectation to a player arises.

  Furthermore, it is preferable that the second transition permission lottery means performs the second permission lottery process when the first special game is finished. By doing so, the second special game can be performed subsequent to the first special game, and the player may have more game media.

  The second transition permission lottery means may perform the second permission lottery process when the second special game ends. By doing so, the second special game can be further performed following the second special game, and even in this case, the player may obtain more game media.

Further, the lottery means performs a lottery of a combination including a small role that is not transferred to either the first special game or the second special game as the extra lottery process, and
It is desirable that the second transition permission lottery means performs the second permission lottery process when winning the small role by the lottery means.

  By doing in this way, the result of the game played last time can be reflected and the possibility of giving an expectation to a player arises.

  In addition, when all of the plurality of reels are stopped by the reel control unit, the second transition permission lottery unit is configured to display the second transition permission lottery unit when the display mode of the symbol is a specific display mode. What performs the permission lottery process is also desirable. The transition to the second special game can be clearly shown to the player in the symbol display mode, and the player's expectation can be enhanced, and the player can also obtain more game media.

  Allowing the transition to special games to be permitted not only in the role lottery but also at other occasions, giving rise to the possibility of increasing expectations for games, and increasing the number of game media that players can acquire There is a possibility that the progress of the game may be developed in various ways.

<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. 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.

  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). This special role includes a big bonus and a regular bonus. In particular, in the present embodiment, the big bonus includes a first type BB combination and a second type BB combination.

  The above-described first type BB combination is a combination that shifts to the first type BB game which is one of the special games. The first type 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 the first type BB game, the bonus 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.
In the present specification, the above-described first type BB game and RB game are referred to as “first special game”.

In addition, the above-described second type BB combination is a combination to shift to the second type BB game which is one of special games. For example, in the second type BB game, the reel is stopped in a very short time after the player operates the stop switch 44a, 44b or 44c. The reel that can be stopped in a very short time after the stop switch is operated is preferably predetermined for at least one specific reel among the three reels 30L to 30R. By performing such stop control, it is possible to make a game that can reflect the player's technique, that is, the so-called level of learning, in the game result.
In the present specification, this second type BB game is referred to as a “second special game”.

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 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, a sub control unit 200 (not shown), a symbol display unit 400, and an image display unit 300 (not shown). And a game medium payout means 600.

<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 is preferably composed of a start switch 42 and stop switches 44a to 44c.

  An opportunity to start the game is determined by a signal issued from the start switch 42 to the main control means 100. An end timing of the game is determined by a signal issued from the stop switches 44a to 44c to the main control means 100.

  Further, the number of medals to be a game bet 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>
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.

  Further, the main control means 100 includes a combination lottery means 120, a reel drive control means 130, a symbol detection means 140, a game control means 150, a permission / rejection information storage means 160, a game medium input number setting means 165, a game The medium payout control means 170, the game medium information storage means 180, the game history storage means 190, and the winning number counting means 195 are included.

<Role lottery means 120>
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 a normal game to a special game (a game that can be expected to win medals more than a normal game and is advantageous to the player). In general, the special combination includes a BB combination (Big Bonus) and an RB combination (Regular Bonus). In the present embodiment, the special combination includes the first type BB combination, the RB combination, and the second type BB combination. The first type BB combination, the RB combination and the second type BB combination are respectively transferred to the first type BB game, the RB game and the second type BB game which are one of the 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, a random number determination means 126, and a lottery probability change means 129. 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 a 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 lottery probability changing means 129 changes the probability of the lottery process for permitting the transition from the normal game to the second type BB game.

  The role lottery means 120 performs “external lottery process”, “first permission lottery process”, and “second permission lottery process”. This extra lottery process includes a first permission lottery process. That is, the process for determining whether or not the winning lottery process is performed includes a first permission lottery process for determining whether or not to allow the transition from the normal game to the first special game. Among the role lottery means 120, the first permission lottery means performs the first permission lottery process. The second permission lottery process is processed separately from the extra lottery process. The second permission permission lottery means performs the second permission lottery process. In addition, it is good also as a structure which can also perform a 2nd permission lottery process by the above-mentioned extra lottery process.

  The “external lottery process” is a lottery process for determining whether or not a game is won or missed. Specifically, it is executed in steps S31 to S35 of FIG.

  In addition, the “first transition permission lottery means” is a period from when the start switch 42 is operated to start the current game to when the stop switch 44a, 44b or 44c is operated to end the current game. In the meantime, the first permission lottery process is performed. As described above, the first transition permission lottery process is included in the extra lottery process and is executed in steps S31 to S35 of FIG. As described above, when the second permission lottery process is performed in the extra lottery process, the second permission lottery process can also be executed in steps S31 to S35 of FIG.

  In addition, the “second transition permission lottery means” has a start switch 42 for starting the current game after the extra lottery process for the game performed at least one time before the current game is performed. A second permission lottery process is performed before the operation. This process is executed in steps S39 to S44 in FIG. 5 or steps S54 to S59 in 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. This process is executed in step S32 of FIG. Further, when a normal game is played and the value of the flag of a specific small role becomes 1, random numbers are extracted. This process is executed in step S40 of FIG. Further, random numbers are extracted when the first type BB game is finished, when the second type BB game is finished, or when a combination of specific symbols is aligned on the active line. This process is executed in step S55 of FIG.

<Random number judging means 126>
The random number judgment unit 126 collates the random number value extracted by the random number extraction unit 124 with the collation data 128 stored in the judgment collation data storage unit 127, thereby determining a role corresponding to the area to which the random number value belongs. . The random number determination unit 126 includes the above-described determination collation data storage unit 127.

  The judgment collation data storage means 127 is assigned to a predetermined storage area of the ROM of the main control board 32 described above. The determination collation data storage unit 127 includes collation data 128.

  The collation data 128 includes a table obtained by dividing a predetermined positive integer range (for example, 0 to 65535) into a plurality of areas. Each of the divided areas corresponds to a plurality of types of roles described above, that is, first type BB role, RB role, second type BB role, bell role, watermelon role, cherry role, replay role, or miss Corresponds to the eight roles. Thus, in the present embodiment, the collation data 128 is composed of eight areas, and the type of role depending on which of the eight areas the random number value extracted by the random number extraction means 124 belongs to. Is determined.

  Further, as shown in FIG. 6 described later, the collation data 128 includes collation data selected when “not in operation”, collation data selected as “inside”, and collation selected when “RB”. Data, collation data selected at “second type BB”, and specific collation data selected in step S39 of FIG. 5 or step S54 of FIG. This specific collation data consists of a plurality of collation data. For each of a plurality of pieces of collation data constituting the specific collation data, a transition hit area and a non-migration area are defined. When the value of the random number extracted by the random number extraction means 124 belongs to the area per transition, the transition from the normal game to the second special game is permitted. Further, when the random number value extracted by the random number extraction means 124 belongs to the shift-off area, the shift from the normal game to the second special game is not permitted. The plurality of pieces of collation data constituting the specific collation data have a hit area and a miss area so that the lottery probabilities of the lottery process are different. As will be described later, based on the history information indicating the history of the game, one verification data is selected from among a plurality of verification data constituting the specific verification data. In particular, it is preferable that one collation data is selected based on the difference between the number of paid out game media and the number of inserted game media. Thus, the lottery probability of the 2nd permission lottery processing can be changed by selecting one collation data among a plurality of collation data which constitute specific collation data. That is, it is possible to change the lottery probability as to whether or not to allow the transition from the normal game to the second special game.

  When winning the first type BB role, the RB role, the second type BB role, the bell role, the watermelon role, the cherry role or the replaying role by the above-mentioned role lottery means 120, Is selected. 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.

<Lottery probability changing means 129>
The lottery probability changing means 129 changes the lottery probability of the second permission lottery process in the role lottery means 120 based on the history information described above. The lottery probability changing means 129 stores random number generating means 122 for generating a random number and a plurality of pieces of collation data for determining whether or not to allow the transition to the second special game based on the value of the random number. It is preferable to include a collation data storage unit 127 and a selection unit (not shown) for selecting one of a plurality of pieces of collation data according to the difference between the number of inserted and paid out game media.

In particular, the lottery probability changing means 129 changes the lottery probability of the second permission lottery process based on the difference between the number of inserted game media and the number of payouts, or the second permitted lottery based on the number of times a predetermined role is won. Change the lottery probability of the process, change the lottery probability of the second permitted lottery process based on the number of times that the transition from the normal game to the first special game is permitted, or shift from the normal game to the second special game It is desirable to change the lottery probability of the second permission lottery process based on the permitted number of times.
The processing by the lottery probability changing means 129 is executed in a subroutine shown 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 signal generated from the start switch 42 or the stop switches 44a to 44c described above. 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 control means”.

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 operation 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 S14 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 a stop operation 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 a stop operation 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 a stop operation 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 a stop operation 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 has three reels 30L, 30C and 30 so that when the winning combination is determined by the above-described random number determining means 126 based on the value of the random number, the winning combination is won. 30R stop control is performed.

<Pattern detection means 140>
The symbol detection means 140 detects the type of the symbol that can be located on the active line or has stopped based on the stop 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 140 detects a symbol type that may stop on the active line by the stop control. Depending on the stop control of the reel drive control means 130, there is a possibility that the type of symbols to be stopped on the effective line is changed within a predetermined range.

  Further, the symbol detection means 140 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 image of the symbol, but when the reel stops, the correspondence between the active line and the symbol If the player 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 to 30R are displaced from the origin when the reels 30L to 30R are at predetermined positions. By obtaining this signal, the positions at which the reels 30L to 30R are displaced from the origin can be obtained.

  The symbol detection means 140 stores a symbol correspondence table (not shown) that defines the relationship between the circumferential positions of the reels 30L to 30R and the types of symbols attached to the positions. The type of symbol can be acquired by searching the symbol correspondence table based on the position indicated by the signals generated from the rotation angle sensors 83a to 83c.

  The process of acquiring the symbol type is executed when the reels 30L, 30C, or 30R are controlled to stop in step S16 of FIG. 4 to be described later.

<Game control means 150>
The game control means 150 controls the progress of the game in the slot machine 10. The main control by the game control means 150 is as follows.
Based on the operation of the bet switches 62 to 66 by the player's operation, the active line is determined and the number of game media to be betted is determined.

  Further, when a start operation signal issued from the start switch 42 described above is detected, a random number is generated by the winning lottery means 120 to draw the type of the winning combination, and the reel rotation control means 132 causes the three reels 30L and 30C to be selected. And 30R.

Next, based on the timing at which the stop switch 44a, 44b or 44c is operated by the reel stop control unit 134 and the type of the lottery selected while referring to the type of symbol detected by the symbol detecting unit 140 The reel corresponding to the operated stop switch among the three reels 30L, 30C and 30R is controlled to stop.
Finally, based on the type of symbol detected by the symbol detection means 140, it is determined whether or not a winning combination has been won, and a winning process such as paying out game media is performed according to the winning combination. .
These main controls are processed by a subroutine shown in FIG.
The game control means 150 includes special game control means 152.

<Special game control means 152>
The special game control means 152 determines whether or not to shift to the first special game or the second special game that is advantageous to the player.

It shall be. Further, the flowcharts shown in FIGS. 4 and 5 and FIGS. 7 to 9 show only one example for executing the control processing in the main control means 100, and are 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.
First, the inserted number is determined based on a signal generated by the player operating the above-described 1-bet switch 62, 2-bet switch 64 or maximum-bet switch 66 (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. This “number of inserted sheets” corresponds to “the number of inserted sheets for starting a game”. This process is performed by the game medium input number setting means 165 shown in FIG.
Next, it is determined whether or not the start switch 42 has been turned on by the player (step S12). When it is determined that the start switch 42 is not turned on, the process of step S12 is repeated.

On the other hand, when it is determined that the start switch 42 has been turned on, the first lottery process subroutine shown in FIG. 5 is called to execute the role lottery process by the role lottery means 120. The value of the winning combination flag indicating that the player has won is set to 1 (step S13).
The process of step S13 is a process in which a combination such as a special combination, a small combination, and a replay is selected by the combination lottery means 120. Specifically, there are three types of special roles: a first type BB role, an RB role, and a second type BB role, and there are three types of small roles: a bell role, a watermelon role, and a cherry role. The lottery process of the role lottery means 120 determines one of a first type BB role, an RB role, a second type BB role, a bell role, a watermelon role, a cherry role, a replay role, or a miss.

Next, according to the winning lottery result of the winning lottery process in step S13, a stop control table (not shown) to be referred to when stopping control of the three reels 30L, 30C and 30R is selected, and the three reels 30L are selected. , 30C and 30R rotation control is started (step S14).
Next, it is determined whether or not any of the three stop switches 44a to 44c is turned on by the player (step S15). When it is determined that any of the three stop switches 44a to 44c is not turned on, this determination process is repeated. When it is determined that any of the three stop switches 44a to 44c is turned on, one of the reels 30L to 30R corresponding to the turned on stop switch is controlled to stop (step S16).

Next, it is determined whether or not all the three reels 30L to 30R are stopped (step S17). When it is determined that all the reels 30L to 30R are not stopped, the process returns to step S15 described above. On the other hand, when it is determined that all the reels 30L to 30R have stopped, a winning process subroutine shown in FIG. 8 to be described later is called to determine whether the combination of symbols corresponding to any of the combinations has stopped on the active line. That is, it is determined whether or not any winning combination has been won (step S18).
Next, the subroutine for the second combination lottery process shown in FIG. 7 is called to execute the combination lottery process by the combination lottery means 120 (step S19), and this subroutine is terminated.

<First role lottery process>
FIG. 5 shows a subroutine of the first combination lottery process that is called and executed in step S13 of the subroutine of FIG. 4 described above.

First, collation data is selected according to the flag value (step S31). In the present embodiment, the flag includes a flag indicating whether or not a predetermined combination is won by the combination lottery means 120 and a flag indicating whether or not a special game is being performed.
There are three flags, F_BB1, F_BB2, and F_RB, indicating whether or not a predetermined combination is won. The flag F_BB1 is a flag indicating whether or not the first type BB combination is won by the combination lottery means 120. When the first type BB combination is won, the value of the flag F_BB1 is 1, and when the first type BB combination is not won, the value of the flag F_BB1 is 0. When the first type BB combination is won and the value of the flag F_BB1 becomes 1, a state referred to as the inside of the first type BB is set.

  The flag F_BB2 is a flag indicating whether or not the second type BB combination is won by the combination lottery means 120. When the second type BB combination is won, the value of the flag F_BB2 is 1, and when the second type BB combination is not won, the value of the flag F_BB2 is zero. In addition, when the second type BB combination is won and the value of the flag F_BB2 becomes 1, a state referred to as the inside of the second type BB is set.

Further, the flag F_RB is a flag indicating whether or not the RB combination is won by the combination lottery means 120. When the RB combination is won, the value of the flag F_RB is 1, and when the RB combination is not won, the value of the flag F_RB is 0. When the RB combination is won and the value of the flag F_RB becomes 1, a state called “inside of the RB” is set.
In addition, although only the flag regarding a special game was shown in the flag which shows whether the winning combination was mentioned above, the flag corresponding to the kind of small role is also defined.

  In addition, there are three flags that indicate whether or not a special game is being performed: F_BB1_EXE, F_BB2_EXE, and F_RB_EXE. The flag F_BB1_EXE is a flag indicating whether or not the first type BB game is being performed. When the first type BB game is being played, the value of the flag F_BB1_EXE is 1, and when the first type BB game is not being played, the value of the flag F_BB1_EXE is 0. The first type BB game is started on condition that the first type BB combination is won.

  The flag F_BB2_EXE is a flag indicating whether or not the second type BB game is being performed. When the second type BB game is being played, the value of the flag F_BB2_EXE is 1, and when the second type BB game is not being played, the value of the flag F_BB2_EXE is 0. The second type BB game is started on condition that the second type BB combination is won.

  The flag F_RB_EXE is a flag indicating whether or not an RB game is being performed. The value of the flag F_RB_EXE is 1 when the RB game is being played, and the value of the flag F_RB_EXE is 0 when the RB game is not being played. The RB game is started on the condition that the RB combination is won.

  In the process of step S31 described above, when the flag values are F_BB1 = 0, F_BB2 = 0, F_RB = 0, F_BB1_EXE = 0, F_BB2_EXE = 0, and F_RB_EXE = 0, that is, a normal game is performed. When it is, the “non-operating” verification table shown in FIG. 6 is selected.

  Further, when the flag value is F_BB1 = 1 or F_BB2 = 1 or F_RB = 1, and F_BB1_EXE = 0, F_BB2_EXE = 0 and F_RB_EXE = 0, that is, in the first type BB, the second type BB When it is either inside or inside the RB, the “inside inside” collation table shown in FIG. 6 is selected.

  Further, when the flag values are F_BB1 = 0 and F_BB2 = 0 and F_RB = 0, and F_BB1_EXE = 1 or F_RB_EXE = 1 and F_BB2_EXE = 0, that is, the first type BB game is performed. When an RB game is being played or when an RB game is being played, the “RB time” verification table shown in FIG. 6 is selected.

  Furthermore, when the flag values are F_BB1 = 0, F_BB2 = 0 and F_RB = 0, and F_BB1_EXE = 0, F_BB2_EXE = 1 and F_RB_EXE = 0, the “second type BB” shown in FIG. A matching table is selected.

  FIG. 6 is a table showing the types of winning lots drawn by the winning lottery means 120 according to the state of the game. As described above, the types of winning combinations include the first type BB role, the RB role, the second type BB role, the watermelon role, the bell role, the cherry role, and the replaying role (replay). In addition to these winning combinations, the combination lottery means 120 also selects a removal.

The combination of symbols corresponding to the first type BB combination is “7”-“7”-“7”. If the combination of “7”-“7”-“7” can be aligned on the active line when winning the first type BB combination, the first type BB combination is won as the first combination. Transition to seed BB game.
The combination of symbols corresponding to the RB combination is “7”-“7”-“card”. If the combination of “7”-“7”-“card” can be aligned on the active line when this RB combination is won, the RB game is determined as having won the RB combination.

  The combination of symbols corresponding to the second type BB combination is “card” − “card” − “card”. If the combination of “card”-“card”-“card” can be aligned on the active line when winning the second type BB role, it is determined that the second type BB role is won and the second type BB role is won. Transition to seed BB game.

  In addition, the combination of symbols corresponding to each of the small role, the bell role, the watermelon role, or the cherry role, is “bell”-“bell”-“bell”, “watermelon”-“watermelon”-“watermelon” or “cherry”. "-Arbitrary-arbitrary. When these small combinations are won, if a combination of the above-described symbols can be aligned on the active line, a predetermined number of medals are paid out for winning the small combination. As described above, when the symbol “cherry” of the left reel 30L is stopped and displayed on the active line, it is assumed that the winning is made regardless of the symbols of the middle reel 30C and the right reel 30R. This was shown as "cherry" -arbitrary-arbitrary.

  Furthermore, the combination of symbols corresponding to the replaying role (replay or RP) is “Plum”-“Plum”-“Plum”. If the combination of the above-mentioned symbols can be aligned on the active line when winning this re-gamer, the next game is performed while maintaining the number of medals inserted (the number of bets). That is, replay can be performed.

  As shown in FIG. 6, there are four game states: “not operating”, “inside”, “when RB”, and “when the second type BB”. The above-described processing of step S31 is performed according to the gaming state in accordance with the “not working” collation table, the “inside” collation table, the “RB” collation table, or the “second type BB” collation. Select a table.

After executing the process of step S31 described above, the random number generated by the random number generator 122 is extracted by the random number extractor 124 (step S32). Next, the random number value extracted in step S32 is collated with the collation table selected in step S31 (step S33). The random number determination means 126 determines the type of the combination by this collation (step S34), and when a predetermined combination is won, the flag value is set according to the type of the winning combination (step S35). The flag set here is a flag indicating whether or not the above-mentioned predetermined combination is won, and includes flags corresponding to the types of small combinations in addition to F_BB1, F_BB2, and F_RB.
By the processes in steps S31 to S35 described above, as shown below, the type of the combination is determined according to the game state.

  When the state of the game is “not operating”, that is, when a normal game is being performed, the role lottery means 120 performs the “first type BB role”, “RB role”, “second type” by lottery processing. One of the “BB role”, “Bell role”, “Watermelon role”, “Cherry role”, “Replay role”, and detachment is selected.

  When the game state is “inside”, that is, when the flag F_BB1, F_BB2, or F_RB has a value of 1, the lottery means 120 performs the “bell role” by lottery processing. , “Watermelon role”, “cherry role” and “replay role”, and one of the detachment are selected.

  Further, when the game state is “RB time”, that is, when the first type BB game or the RB game is being performed, the role lottery means 120 performs the “bell role”, “watermelon role” and Select "Cherry" and one of the detachments.

  Furthermore, when the game state is “at the time of the second type BB”, that is, when the second type BB game is being performed, the role lottery means 120 performs the “RB role” and the “replay role” by the lottery process. , And one of the outliers. In this case, the three small roles “bell role”, “watermelon role” and “cherry role” are always selected without performing the lottery process. That is, when the second type BB game is being played, the flag values corresponding to the “bell role”, “watermelon role” and “cherry role” are set to 1 so that these roles can be won. ing.

  The first permission lottery process is performed by the processes in steps S31 to S35 described above. This first permission lottery process is performed after the start switch 42 is operated to start the current game and until the stop switch 44a, 44b or 44c is operated to end the current game. That's fine.

  After performing the process of step S35 mentioned above, it is judged whether transfer to 1st type BB game, RB game, or 2nd type BB game was permitted based on the value of a flag (step S36). When it is determined that the migration is permitted, the number of times the migration is permitted is calculated, and the value is stored (step S37). Specifically, when the transition to the first type BB game is permitted, 1 is added to the number of times the transition to the first type BB game has been permitted so far, and the value is stored. When the transition to the RB game is permitted, 1 is added to the number of times the transition to the RB game has been permitted so far, and the value is stored. Further, when the transition to the second type BB game is permitted, 1 is added to the number of times the transition to the second type BB game has been permitted so far, and the value is stored.

  When it is determined in step S36 that the transition is not permitted, or when the process of step S37 is executed, whether or not the normal game is being performed and the value of the flag of the specific small role is 1 or not Is determined (step S38). When it is determined that a normal game is being performed and the value of the flag of a specific small role is 1, a specific verification table (not shown) is called by calling a specific verification data selection subroutine shown in FIG. ) Is selected (step S39). This specific collation table is different from that shown in FIG. 6 and is used to determine whether or not to allow the transition to the second type BB game.

  Next, the random number generated by the random number generator 122 is extracted by the random number extractor 124 (step S40). Next, the random number value extracted in step S40 is collated with the collation table selected in step S39 (step S41). As a result of this collation, it is determined whether or not the transition to the second type BB is permitted (step S42). When it is determined that the transition to the second type BB is permitted, 1 is added to the number of times the transition to the second type BB game has been permitted so far, and the value is stored (step S43), and the value of the flag F_BB2 Is set to 1 (step S44).

  When it is determined in the determination process in step S38 that a normal game is not being performed, or when it is determined that the value of the flag for the specific small role is not 1, the second type is determined in the determination process in step S42. When it is determined that the transition to BB is not permitted, or when the process of step S44 is executed, this subroutine is terminated.

  The second permission lottery process is performed by the processes in steps S39 to S44 described above. This second permission lottery process is performed until the start switch 42 is operated to start the current game after the extra lottery process for the game performed at least one time before the current game is performed. It may be performed between.

<Second role lottery process>
FIG. 7 shows a subroutine of the second combination lottery process that is called and executed in step S19 of the subroutine of FIG. 4 described above.
First, it is determined whether or not the first type BB game is finished (step S51). This determination is, for example, that the number of game media paid out in the first type BB game is a predetermined number. Specifically, when the number of paid out medals reaches 466 or more, it is determined that the first type BB game is finished.

  When it is determined that the first type BB game has not ended in the determination process of step S51, it is determined whether or not the second type BB game has ended (step S52). This determination is, for example, a process of determining whether or not the number of game media paid out during the first type BB game exceeds a predetermined number, or whether or not a predetermined combination is won. is there. Specifically, it is determined that the second type BB game has ended when the number of paid-out medals reaches 253 or more, or when the RB combination is won.

  When it is determined that the second type BB game has not ended in the determination process of step S52, it is determined whether or not a specific symbol combination is aligned on the active line (step S53). In particular, it is preferable that this specific symbol combination does not pay out game media to the player.

  When it is determined in step S53 that the specific symbol combination is not on the valid line, this subroutine is immediately terminated.

  When it is determined that the first type BB game is ended in the determination process of step S51 described above, when it is determined that the second type BB game is ended in the determination process of step S52, or a specific symbol is determined in the determination process of step S53. When it is determined that the combinations are aligned on the effective line, a subroutine for selecting specific collation data shown in FIG. 9 to be described later is called to select a specific collation table (step S54). This specific collation table is different from that shown in FIG. 6 and is used to determine whether or not to allow the transition to the second type BB game.

  Next, the random number generated by the random number generator 122 is extracted by the random number extractor 124 (step S55). Next, the random number value extracted in step S55 is collated with the collation table selected in step S54 (step S56). As a result of this collation, it is determined whether or not the transition to the second type BB is permitted (step S57). When it is determined that the transition to the second type BB is permitted, 1 is added to the number of times the transition to the second type BB game has been permitted so far, and the value is stored (step S58). The value of the flag F_BB2 Is set to 1 (step S59).

  The second permission lottery process is performed by the processes in steps S55 to S59 described above. This second permission lottery process is performed until the start switch 42 is operated to start the current game after the extra lottery process for the game performed at least one time before the current game is performed. It may be performed between.

  When it is determined in the determination process of step S57 that the transition to the second type BB is not permitted, or when the process of step S59 is executed, this subroutine is terminated.

<Winning process>
FIG. 8 shows a winning process subroutine called and executed in step S18 of the subroutine of FIG. 4 described above.
First, it is determined whether or not the combination of symbols corresponding to any combination has stopped on the active line, that is, whether or not any combination has been won (step S61). If it is determined that a winning combination has been won, the number of winnings in that winning combination is calculated and stored (step S62). Specifically, 1 is added to the number of times that the winning combination has been won so far, and the value is stored.

  Next, it is determined whether or not the first type BB combination or the second type BB combination has been won (step S63). If it is determined that neither the first type BB combination nor the second type BB combination has been won, it is determined whether or not a re-game combination has been won (step S64). If it is determined that the re-game combination is not won, the number of medals to be paid out is determined according to the combination (step S65). Here, the combination from which the medals are paid out is a small combination of any one of the combination of watermelon, combination of bell and cherry. The relationship between the type of the combination and the number of medals to be paid out is stored in advance as a table in the combination-based game medium number storage means (not shown) of the game medium payout number determination means 172 as described above. ing. The process of step S65 is performed by referring to this table.

  After executing the processing of step S65, the difference number in the game played this time, that is, the game of the single stroke or the unit game played this time is calculated (step S66). Specifically, the difference between the inserted number determined in step S11 in FIG. 4 and the payout number determined in step S65 is calculated. Next, the cumulative difference number is calculated and stored (step S67). This cumulative difference number is obtained by adding the difference numbers calculated in a single-game or unit game that has been performed so far.

  When it is determined that the first type BB combination or the second type BB combination is won in the determination process of step S63 described above, when it is determined that the re-game combination is won in the determination process of step S64, or the process of step S67 is performed. When executed, this subroutine is terminated.

<Specific verification data selection process>
FIG. 9 shows a subroutine of processing for selecting specific collation data that is called and executed in step S39 of FIG. 5 or step S54 of FIG.
First, it is determined whether or not the specific collation data is to be changed based on the cumulative difference number calculated in step S67 of FIG. 8 (step S71). For example, it is determined whether or not the value of the cumulative difference number is included in a predetermined range. In addition, a plurality of ranges may be defined as the predetermined range, and when included in any one of the ranges, the condition of step S71 may be satisfied.

If it is determined in step S71 that the specific collation data is to be changed, one of a plurality of pieces of collation data constituting the specific collation data is selected according to the value of the accumulated difference number (step S72), and this subroutine is executed. finish.
If it is determined in step S71 that the specific collation data is not to be changed, it is determined whether or not the specific collation data is to be changed based on the number of winnings for a predetermined combination (step S73). For example, it is determined whether or not the number of winnings is included in a predetermined range. A plurality of ranges may also be defined for the predetermined range, and the condition of step S73 may be satisfied when included in any one of the ranges.

If it is determined in step S73 that the specific collation data is to be changed, one of a plurality of pieces of collation data constituting the specific collation data is selected according to the number of wins (step S74), and this subroutine is terminated.
If it is determined in step S73 that the specific collation data is not to be changed, it is determined whether or not the specific collation data is to be changed based on the number of permitted transfers (step S75). For example, it is determined whether or not the number of permitted transitions is within a predetermined range. Also, a plurality of ranges may be defined for the predetermined range, and the condition in step S75 may be satisfied when included in any one of the ranges.

If it is determined in step S75 that the specific collation data is to be changed, one of a plurality of pieces of collation data constituting the specific collation data is selected according to the number of permitted transitions (step S76), and this subroutine is terminated. .
If it is determined in step S75 that the specific collation data is not to be changed, this subroutine is immediately terminated.

  By executing the process of step S72, S74 or S76 described above, one of the plurality of pieces of collation data constituting the specific collation data is selected. As described above, each of the plurality of collation data has a transition hit area and a shift miss area, and the hit area and the miss area are determined so that the lottery probabilities of the lottery process are different. By selecting one of the plurality of verification data, it is possible to change the lottery probability as to whether or not to allow the transition from the normal game to the second special game.
