Abstract

<P>PROBLEM TO BE SOLVED: To prevent players from starting a game by casting game media with its number less than the maximum number to be cast by mistake against their wills. <P>SOLUTION: When a minor win is won, the credit counts c and the number m of put out medals are added up and it is judged whether the added value (m+c) exceeds "48" as the upper limit of the credit counts or not. When the added values (m+c) exceeds "48", the number of game media is put out by subtracting "48" from the added value (m+c). Otherwise, it is determined whether the number n of medals left after the division of the added value (m+c) by three is zero or not. When the remainder n is zero, the number m of put out medals is added to the credit counts c. Otherwise, a value (m-n) obtained by subtracting the number of medals as the remainder n from the number m of put out medals is added to the credit counts c. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a gaming machine used in a game hall such as a pachinko parlor.

  Slot machines used in pachinko parlors are called pachislot machines. In the pachislot machine, when the start lever is pressed after the medal is inserted, a winning combination lottery is performed to determine one of a plurality of types of winning combinations or lose, and the reel is rotated to start a game. When the rotation of the reel starts, the operation of the stop button is validated, and when the stop button is pressed, the rotating reel stops and one game ends. When the reels are stopped, so-called pull-in / kick-out control is performed, and whether or not a prize has been won is displayed according to the result of the winning combination lottery.

In a pachislot machine, you can play a game by inserting the number of medals arbitrarily selected from 1 to 3 in one game, but the smaller the number of inserted, for example the winning probability of winning the winning combination lottery It becomes disadvantageous in obtaining a gaming privilege such as lowering. For this reason, it is common for a player to play a game by inserting three medals, which is the upper limit of the inserted number. Since it is not convenient to insert a medal from the medal insertion slot for each game when the medal is inserted, the pachislot machine has a credit function (Patent Document 1), and the player presses the bet button. It is possible to play a game by inserting a medal that has been credited in advance.
JP 2003-154056 A

  However, in the pachislot machine in which the number of inserted medals can be arbitrarily selected as described above, the player mistakenly inserts one or two medals into a game, that is, the maximum number of inserted medals is less than three. A game may be played with a medal inserted. In this case, since the winning combination lottery is performed under an unfavorable condition as compared with the case where three medals are inserted, the player has a large sense of loss of medals and the interest in the game may be reduced.

  In order to solve the above problems, the present invention provides a gaming machine that can prevent a player from playing a game by inserting less than the maximum number of game media by mistake, contrary to the will of the player. The purpose is to provide.

  In order to achieve the above object, the gaming machine of the present invention is credited with a game medium inserted from an insertion slot, and can play a game by inserting the credited game medium. A game can be played by inserting a selected number of game media up to the specified maximum number of games, and when a lottery executed in the game process is won, a gaming privilege is granted and the game starts. In the gaming machine in which the winning probability of the lottery decreases as the number of inserted game media selected prior to the number decreases, the number of credits of the game media becomes a multiple of the maximum thrown number at a predetermined preset opportunity. And a credit amount adjusting means for paying out the credited game medium. “Insert” in “Insert game media from the slot” means to actually enter the game media, “Insert a credited media” and “Insert game media” "Insert" indicates that a medal is inserted when a game is played, that is, a so-called game medium is "bet". “Before starting a game” means “betting” a game medium before starting a game.

  In addition, the winning combination or loser from which the specified number of game media can be obtained is determined by the winning combination lottery, and the result of the winning combination lottery is displayed by displaying the variation of the symbol, and the winning symbol corresponding to the winning combination is won. When the winning combination is stopped, the corresponding winning combination wins and the specified number of game media are credited, and the credit amount adjusting means is configured to receive the specified number of gaming media and the winning media when winning the winning combination. It is preferable to pay out a number of game media corresponding to the remainder obtained by dividing the total of the credits before winning the winning combination by the maximum inserted number.

  The credit amount adjusting means preferably pays out the gaming medium credited when the credit amount is less than the maximum inserted number.

  The credit amount adjusting means determines whether or not the credit number is less than the maximum inserted number after a predetermined time elapses after a game medium is inserted from the insertion slot and the game medium is added to the credit. It is preferable to determine and pay out the gaming media credited when the credit number is less than the maximum inserted number.

  The credit amount adjusting means invalidates a game medium insertion operation credited when the credit number is less than the maximum inserted number, and is credited when the credit number is equal to or greater than the maximum inserted number. It is preferable to validate the game medium input operation.

  According to the first aspect of the present invention, if credits are used, it becomes possible to always play the game with the maximum number of game media inserted, and it is less than the maximum input number by mistake, contrary to the intention of the player. It is possible to prevent a game from being played by inserting a game medium.

  According to the second aspect of the present invention, it is possible to adjust the number of credits when the number of credits varies due to the payout of game media, and the processing associated with the adjustment of the number of credits can be performed efficiently.

  According to the third aspect of the present invention, when the number of credited game media is less than the maximum inserted number, it is possible to prevent the game from being performed by inserting less than the maximum inserted number of game media. Therefore, it is possible to more reliably prevent a player from playing a game by inserting less than the maximum number of game media by mistake, contrary to the will of the player.

  According to the fourth aspect of the present invention, it is possible to eliminate the inconvenience that the game medium is paid out when the game medium is inserted from a state where the credit is less than the maximum inserted number. Can be increased.

  According to the fifth aspect of the present invention, when the number of credited game media is less than the maximum inserted number, it is possible to prevent the game from being played by inserting less than the maximum inserted number of game media. Therefore, it is possible to more reliably prevent a player from playing a game by inserting less than the maximum number of game media by mistake, contrary to the will of the player.

  As shown in FIG. 1, the slot machine (game machine) 11 includes a slot machine main body 12 and a front door 13. The slot machine body 12 includes a storage box 12a. The storage box 12a stores a reel unit, a control board, a hopper device, and the like. The front door 13 is vertically divided into an upper door 13a and a lower door 13b. The inside of the slot machine body 12 is opened and closed by an upper door 13a and a lower door 13b.

  A display window 14 is provided on the upper door 13a. In the back of the display window 14, a first reel 15a, a second reel 15b, and a third reel 15c that are rotatable are provided. A plurality of types of symbols are arranged on the outer peripheral surfaces of the first to third reels 15a to 15c. When the first to third reels 15a to 15c are stopped, three symbols are displayed per reel through the display window 14. The In the slot machine 11, a total of five winning effective lines 16, consisting of three laterally and two diagonally, are set. Then, whether or not the winning combination has been won is displayed by the combination of symbols stopped on the winning winning line 16 when the first to third reels 15a to 15c are stopped.

  A liquid crystal display 17 is provided on the side of the display window 14. From the liquid crystal display 17, an effect image for suggesting or notifying the result of the winning combination lottery is displayed.

  On the lower door 13b, a medal insertion slot (insertion slot) 19 for inserting medals (game media), a start lever 20 for starting the game by starting the rotation of the first to third reels 15a to 15c, and the like are rotating. The medals are paid out to the first to third stop buttons 21a to 21c for stopping the reel, the bet button 22 for betting credited medals, the payout port 24 for paying out medals, and the medal tray 25 for storing the paid out medals. .

  In the slot machine 11, a game is performed by inserting medals arbitrarily selected from 1 to 3 in one game, and the maximum number of medals in one game is three. Yes. When one medal is inserted, the winning line 16 in the horizontal direction and in the center, when two medals are inserted, three winning lines 16 in the horizontal direction are inserted, and when three medals are inserted, two horizontal lines are displayed in the diagonal direction. A total of five winning active lines 16 including books are activated. When four or more medals are inserted from the medal slot 19 at a time, the third medals are placed (betted) prior to the start of the game, and the third and subsequent medals are 48 medals. Credited to the upper limit. The number of credited medals (hereinafter referred to as “credit number”) is displayed from a credit indicator 23 provided below the first to third reels 15a to 15c. A 7-segment display is used for the credit display 23, and the number of credits is displayed with the inserted fourth medal as the number of credits “1”. The credited medal is inserted by the bet button 22. The operation of the bet button 22 is invalidated when the number of credits is 1 to 2, and the operation is validated when the number of credits is 3 or more. Since the upper limit of the number of credits is “48”, if 48 medals are credited, three medals can be inserted and 16 games can be played without leaving one or two medals.

  When the start lever 20 is pressed after the medal is inserted, a winning combination lottery is performed to determine one of a plurality of types of winning combinations or a loss, and the first to third reels 15a to 15c rotate all at once. The symbols are displayed in a variable manner. The winning combination includes a BB that shifts to a BB mode that is more advantageous to the player than the normal mode when winning, a small role where a prescribed number of medals can be obtained when winning, and a replay that allows the next game to be performed without inserting medals when winning Is set. Note that a plurality of small combinations are provided so that the number of medals obtained is different.

  When the first to third reels 15a to 15c start rotating and the first to third stop buttons 21a to 21c are operated and then pressed, the corresponding first to third reels 15a to 15c are pressed. Stops individually. When the combination of symbols stopped on the winning winning line 16 is a winning symbol combination corresponding to the winning combination won in the winning combination lottery, the winning combination wins.

  As shown in FIG. 2, the operation of the slot machine 11 is controlled by the game control board 60. The game control board 60 includes a CPU 61 and a memory 62. In the ROM area of the memory 62, game execution programs and execution data are stored. The CPU 61 performs a game execution process by reading a game execution program and execution data from the memory 62. The RAM area of the memory 62 is used for temporary storage or rewriting of a winning flag (a flag indicating the type of the winning combination won in the winning combination lottery) and data used for each game.

  The medal sensor 63 detects an appropriate medal inserted from the medal insertion slot 19 and inputs a medal detection signal to the CPU 61. The CPU 61 counts the number of medals inserted based on the detection signal from the medal sensor 63, validates the winning payline 16 and validates the operation of the start lever 20 based on the counted number of medals. When four or more medals are inserted, the CPU 61 sets the fourth medal as the credit number “1” and writes the credit number in the credit number storage unit 62 a provided in the RAM area of the memory 62. When the bet button 22 is pressed, the winning line 16 is validated by subtracting (rewriting) the credit amount written in the credit amount storage unit 62a. In addition, the CPU 61 performs display control of the credit indicator 23 and displays the credit number written in the credit amount storage unit 62a from the credit indicator 23. Further, when the number of credits written in the credit amount storage unit 62a is “48”, the medal inserted from the medal slot 19 is returned to the medal tray 25 without performing medal credit.

  The start signal sensor 64 detects that the start lever 20 has been pressed. When it is detected that the start lever 20 is pressed after the operation is validated, a game start signal is input from the start signal sensor 64 to the CPU 61.

  The CPU 61 includes a winning combination determining unit 61a, and operates the winning combination determining unit 61a in response to the game start signal. In the winning combination determination unit 61a, BB, a small combination, a replay or a loss is determined by a winning combination lottery using an electronic random number. The winning combination lottery unit 61a has a one-sheet lottery table used when one medal is inserted, a two-sheet lottery table used when two medals are inserted, and three medals are inserted. A three-sheet lottery table used sometimes is provided, and a winning combination lottery is performed using a lottery table corresponding to the number of inserted medals. The three-sheet lottery table has the highest winning probability for each of BB, small role, and replay compared to the other tables, and the one-sheet lottery table has other winning probabilities for BB, small role, and replay. Number of winning random numbers so that the winning probability of each of BB, small role, and replay is intermediate between the three-sheet lottery table and the one-sheet lottery table. Is decided. For this reason, as the number of inserted medals decreases, the probability that a winning combination that is a gaming privilege is given decreases.

  When any winning combination is won in the winning combination lottery, a winning flag indicating the type is written in the RAM area of the memory 62. The BB flag is cleared when the BB wins, and the other flags are cleared when the winning game ends. Thereby, when BB is won, the right to win is carried over until BB wins. When the winning combination lottery is completed, the CPU 61 starts the rotation of the first to third reels 15a to 15c.

  The stop signal sensor 65 detects that the first to third stop buttons 21a to 21c are pressed. When the first to third stop buttons 21 a to 21 c are pressed, stop signals for the first to third reels 15 a to 15 c are individually input to the CPU 61. When the stop signal is input, the CPU 61 determines whether or not the first to third reels 15a to 15c are rotating. If the first to third reels 15a to 15c are rotating, the reel driving is performed. The controller 66 is activated. Then, the CPU 61 performs stop control of the first to third reels 15 a to 15 c corresponding to the pressed first to third stop buttons 21 a to 21 c via the reel drive controller 66. As the stop control of the first to third reels 15a to 15c, known pull-in control is performed. In the pull-in control, the number of frames required until the first to third reels 15a to 15c are stopped ranges from 0 to 4 frames for 5 symbols including the symbols on the winning winning line 16, that is, a range of 5 frames (hereinafter, “ (Referred to as “retraction range”). If the winning symbol (the symbol corresponding to the winning combination won in the winning combination lottery) is included in the drawing range of 5 frames when the first to third stop buttons 21a to 21c are pressed, The symbol stops on the winning winning line 16.

  Whenever each of the first to third stop buttons 21a to 21c is pressed, the CPU 61 stops the first to third reels 15a to 15c based on the rotational positions of the first to third reels 15a to 15c. The type of the symbol that stops on the winning effective line 16 is identified, and this is written in the RAM area of the memory 62. Then, when all the stop buttons are pressed, it is determined whether or not the symbol combination is a combination corresponding to the winning combination won in the winning combination lottery, that is, the winning combination winning determination is performed. When the small combination wins, the CPU 61 refers to the payout table stored in the ROM area of the memory 62, identifies the number of medals to be paid out for the small combination, and stores the identified number of payouts in the RAM of the memory 62. Write to the area. Then, the hopper device 67 is driven to pay out medals.

  The credit number adjusting unit (credit number adjusting means) 61b adjusts the number of medals to be paid out when winning a small role so that the number of credits of medals is a multiple of three, which is the maximum number of inserted coins.

  The flow of credit amount adjustment processing by the credit amount adjustment unit 61b will be described with reference to the flowchart shown in FIG.

  As shown in FIG. 3, first, the credit amount adjusting unit 61b refers to the credit storage unit 62a after a predetermined time elapses when a medal is inserted through the medal slot 19 and a medal is credited. It is then determined whether the number of credits is less than “3”. If the credit number is less than “3”, the credited medal is paid out, and if the credit number is not less than “3”, the medal is kept credited. This prevents the number of credits from becoming less than three, which is the maximum number of medals inserted.

  As a result of the game, when the small combination wins, the credit amount adjusting unit 61b refers to the credit number storage unit 62a to identify the credit number c, and refers to the RAM area of the memory 62 to determine the number m of paid-out medals. Identify

  Thereafter, the identified credit number c and the payout number m are added, and it is determined whether or not the added value (m + c) exceeds “48” which is the upper limit of the credit number.

  If the added value (m + c) exceeds the upper limit “48” of the number of credits, the number obtained by subtracting “48” from the added value (m + c) is paid out and adjusted to the upper limit of the number of credits “48”. To do. As a result, the number of credits is adjusted to a multiple of three, which is the maximum number of medals inserted.

  If the added value (m + c) does not exceed “48” which is the upper limit of the number of credits, whether or not the remainder n obtained by dividing the added value (m + c) by 3 is 0 Determine whether.

  If the remaining n number is 0, the payout number m is added to the credit number c, and the process ends. Since the added value (m + c) does not exceed “48” which is the upper limit of the number of credits, and the added value (m + c) is a multiple of three that is the maximum number of inserted medals, the number of credits is not adjusted. The added value (m + c) is used as the credit number as it is, and the process is terminated.

  If the remaining n number is not 0, the subtraction value (mn) obtained by subtracting the remaining n medals from the paid-out number m is added to the credit number c, and the process ends.

  As described above, by adjusting the number of credits c to a multiple of three, which is the maximum number of games that can be inserted, if the player presses the bet button 22, three medals are reliably inserted every game. It becomes possible to play a game, and a player can prevent a game from being lost by mistakenly inserting one or two medals and playing a game.

  In the above embodiment, when the number of credits is less than “3”, it is possible to prevent one or two medals from being played by paying out credited medals. It is possible to obtain the same effect by taking measures.

  For example, as shown in FIG. 4, when the bet button 22 is pressed, the credit amount adjustment unit 61b refers to the credit storage unit 62a and determines whether or not the credit amount is less than “3”. When the number of credits is less than “3”, the operation of the bet button 22 is invalidated, the medal is not inserted, and when the number of credits is “3” or more, the operation of the credit button 22 is validated, Insert 3 medals. This prevents the number of credits from becoming less than three, which is the maximum number of medals inserted. The subsequent processing is the same as that in the flowchart of FIG. It should be noted that the determination of whether to enable / disable the operation of the bet button 22 and switching may be performed at an appropriate timing, such as when a game is not performed for a predetermined time or when a game is started (when the start lever is pressed). .

  In the above-described embodiment, the credit number adjustment unit 61b performs the credit number adjustment process at the time of winning a small role, but may be performed at an appropriate timing. The timing for performing the process includes, for example, the time when the game is not performed (the time elapsed since the game is finished) reaches a predetermined time. When a game is played with 4 or more medals inserted through the medal slot 19, the game can be prevented from being mistakenly inserted with 1 or 2 medals.

  In the above embodiment, a reel drive type slot machine has been described as an example. However, other gaming machines such as a slot machine that displays a symbol on a liquid crystal display, a slot machine that uses a game ball, and a pachinko machine, for example. The present invention may also be applied.

It is a perspective view which shows the external appearance of a slot machine. It is a block diagram showing an outline of an electrical configuration of the slot machine. It is a flowchart which shows the flow of the credit adjustment process by a credit number adjustment part. It is a flowchart which shows the flow of a credit adjustment process in the case of switching validation / invalidation of operation of a bet button by a credit amount adjustment part.
