Abstract

<P>PROBLEM TO BE SOLVED: To provide a game machine which prevents a fall in operation ratio by solving the problem that fall in the frequency of representation due to a decrease in the amount of possessed tokens forces the most of players to stop playing the game when the possessed tokens are used up so that the operation ratio of a pachislo machine is decreased to cause a loss of a profit of a pachinko parlor. <P>SOLUTION: A representation control section actuates a changeover drawing section when the remaining number of the tokens possessed by the player is 10 or less. A table changeover drawing is executed in the changeover drawing section. When the prizewinning is drawn in the table changeover drawing, the representation control section feeds a signal indicating a second representation table to a representation drawing section. Responding to this, the representation drawing section executes the representation drawing using the second representation table. Thereby, the probability of the representation display being displayed becomes higher than the time before the remaining number of the tokens becomes 10 or less. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a gaming machine on which an effect suggesting whether or not a winning combination has been won is displayed.

  In this specification, a pachislot machine is described as an example of one of the gaming machines, so that explanation is given using medals as gaming media, but the gaming media includes other media such as coins and pachinko balls. In addition, “inserting a medal” includes betting a credited medal with a bet button or the like in addition to actually inserting a medal into a medal slot. Furthermore, a state where the symbols are aligned on the winning line is defined as “winning”.

  Slot machines installed in amusement halls such as pachinko parlors are called pachislot machines. In a pachinko parlor, a medal can be lent by exchanging bills for medals with a medal lending machine. The medal is given a certain value, and the acquired medal can be exchanged for various prizes according to the number of medals.

Generally, in a pachislot machine, whether or not a winning combination is won is determined by lottery, and the number of medals that a player can acquire is determined depending on the type of winning combination. To win a medal, it is necessary to win the winning role. In order to win the winning combination, it is only necessary to stop the reel at an appropriate timing while observing the rotating reel, and stop the symbol corresponding to the winning combination on the winning line. However, for low-skilled players, it may not be possible to obtain a medal because the reel-stopping operation cannot be performed at the timing when the winning winning team wins. There was something to hold me. For this reason, for example, when a predetermined condition is satisfied, it has been proposed to change the winning combination probability so that the difference between the number of inserted medals and the number of paid out medals falls within a predetermined range. As a result, it is possible for the player to play the game without significantly reducing medals.
JP 2001-120726 A

  By the way, in recent pachislot machines, for example, a liquid crystal panel, sound, lamps, etc. are used to indicate the results of the lottery, and even if the lottery is lost, the player has a sense of expectation that he has won the winning role. What you can do is mainstream. In addition, by performing the performance, even a beginner with little knowledge of the game can detect the winning combination won in the winning combination lottery, thereby preventing an unfair feeling about the game. And what kind of production will be performed is one of the important factors when a player chooses a pachislot machine to play a game, and each manufacturer provides pachislot machines that have devised a method of production Tend to.

  By the way, in the slot machines as described above, whether or not to produce an effect is determined by lottery, and the opportunity for changing the effect frequency is, for example, when a winning role with a lot of medals can be won or when a player It was set when game conditions were met, such as when the game mode was changed to an advantageous game mode. For this reason, when the amount of medals owned is reduced and the frequency of performance is low, the player has almost stopped playing the game after using the owned medals. This led to a decline in the operating rate of pachislot machines and a loss of profits at pachinko parlors.

  Moreover, instead of the method of directly exchanging bills directly with medals, for example, a player purchases a prepaid card, inserts it into a medal lending machine, and receives a predetermined number of medals until the purchase amount of the prepaid card is reached. It has been studied to lend medals to players using a prepaid card method. However, when medals are lent by the prepaid card method, when the number of medals that can be lent at a time is small, the timing at which the player stops the game as compared to the method of exchanging bills for medals. Since the degree of freedom increases, there is a risk that the game will be stopped immediately if the frequency of performance is reduced. As a result, the operating rate of the pachislot machine is further reduced.

  An object of this invention is to provide the gaming machine which can prevent the fall of an operation rate.

  The gaming machine according to claim 1 rents a predetermined number of game media to a player up to the number corresponding to the amount recorded in the prepaid card, and a game is played with the lent game media, In a gaming machine that executes an effect suggesting whether or not the winning combination has been won, whether or not to execute the effect by a plurality of effect tables having different probabilities that the effect will be executed, and lottery using the effect table An effect lottery means for determining whether or not a lending number storage means for writing the lending number of gaming media, and a total number of gaming media thrown after the lending number is written, after the lending number is written Net increase number calculating means for calculating a net increase number subtracted from the total payout number of game media paid out as a result of playing a game with the inserted game media, and the lending And the remaining number calculating means for calculating the total of the number of net increase and the net increase number, and when the calculation result in the remaining number calculating means is less than or equal to a preset predetermined number, the lottery used in the effect lottery means Effect control means for switching the effect table to the effect table having a higher probability that the effect is executed than before the predetermined number or less is provided.

  Further, as the effect, a continuous effect that is executed over a plurality of games is set, and the predetermined number of games can be reduced with the predetermined number of game media than the number of games in the continuous effect. It is preferable to set the number.

  And a switching lottery means for determining, by lottery, whether or not to cause the effect control means to switch the effect table when the calculation result of the remaining number calculating means is equal to or less than a predetermined number set in advance. It is preferable to provide it.

  The gaming machine according to claim 4 suggests whether or not a predetermined number of game media are lent to the player up to the amount corresponding to the amount recorded on the prepaid card, and whether or not the winning combination is won. In a gaming machine that executes an effect, an effect storage means storing effect data for executing the effect, a rented number storage means in which the rented number of game media is written, and the rented number are written. Net increase calculation for calculating the net increase by subtracting the total number of game media inserted from the total amount of game media paid out as a result of the game being played with the game media inserted after the lending number was written Means, a remaining number calculating means for calculating the sum of the rented number and the net increased number, and a calculation result by the remaining number calculating means is less than a predetermined number set in advance. If it becomes the one in which the effect data provided and presentation control means for executing the presentation is read from the presentation storage means.

  Further, as the effect, a continuous effect that is executed over a plurality of games is set, and the predetermined number of games can be reduced with the predetermined number of game media than the number of games in the continuous effect. It is preferable to set the number.

  Also, a read lottery means for determining, by lottery, whether or not to cause the effect control means to read out the effect data when the calculation result by the remaining number calculating means is equal to or less than a predetermined number set in advance. It is preferable to provide it.

  In the gaming machine according to claim 1, when the sum of the number of lent out game media and the net increase in the number of game media is equal to or less than a predetermined number set in advance, the probability that an effect is executed increases. It is possible to increase the frequency of production when the remaining game media owned by the player becomes small. Thereby, when the use of the owned game medium is completed, it is possible to increase the player's expectation for winning the winning combination, and to prevent the player from stopping the game. Therefore, it is possible to prevent a decrease in the operating rate of the gaming machine.

  Further, as the effect, a continuous effect that is executed over a plurality of games is set, and the predetermined number of games can be reduced with the predetermined number of game media than the number of games in the continuous effect. Since the number is set, it becomes possible for the game that the player has finished using the game medium to be a game in the middle of continuous production, and when the player finishes using the game medium that he owns, the player stops the game Can be prevented.

  In addition, if the sum of the number of rented game media and the net increase in the number of game media falls below a predetermined number set in advance, whether or not to increase the probability that an effect will be executed is determined by lottery. It is possible to prevent the production frequency from increasing every time the use of the game medium is completed, and to prevent the player from perceiving the relationship between the possession amount of the game medium and the production frequency. Accordingly, it is possible to more reliably prevent the player from stopping the game when the use of the owned game medium is completed.

  In the gaming machine according to claim 4, when the sum of the number of lent out game media and the net increase in the number of game media is equal to or less than a predetermined number set in advance, the effect is forcibly executed. An effect can be executed when there is little remaining game media to play. Thereby, when the use of the owned game medium is completed, it is possible to increase the player's expectation for winning the winning combination, and to prevent the player from stopping the game. Therefore, it is possible to prevent a decrease in the operating rate of the gaming machine.

  Further, as the effect, a continuous effect that is executed over a plurality of games is set, and the predetermined number of games can be reduced with the predetermined number of game media than the number of games in the continuous effect. Since the number is set, it becomes possible for the game that the player has finished using the game medium to be a game in the middle of continuous production, and when the player finishes using the game medium that he owns, the player stops the game Can be prevented.

  In addition, when the total of the number of lent out game media and the net increase in the number of game media is equal to or less than a predetermined number set in advance, it is determined by lottery whether or not the performance is forcibly executed. It is possible to prevent the production frequency from increasing every time the use of the medium is completed, and to prevent the player from perceiving the relationship between the possession amount of the game medium and the production frequency. Accordingly, it is possible to more reliably prevent the player from stopping the game when the use of the owned game medium is completed.

  FIG. 1 shows an appearance of the slot machine 10, and first, an outline of a game flow of the slot machine 10 will be described. The slot machine 10 is set with two types of game modes, a normal mode and a BB mode. If BB is won in the winning combination lottery in the normal mode and BB is won, the mode is changed from the normal mode to the BB mode. In the BB mode, it becomes easier to acquire medals than in the normal mode.

  The slot machine 10 is provided with a housing 10 a including a storage box 11 and a front door 12. A display window 13 is provided on the front door 12. A first reel 14a, a second reel 14b, and a third reel 14c are rotatably incorporated in the back of the display window 13. As is well known, a plurality of types of symbols are arranged at regular intervals on the outer periphery of the first to third reels 14a to 14c. When the reels are stopped, three symbols per reel can be observed through the display window 13. In addition, a total of five straight winning effect lines, each of which is a combination of the symbols of each reel, are set with three horizontal lines and two diagonal lines.

  When three medals are inserted into the medal slot 15 prior to the start of the game, five winning valid lines are activated. Further, it is possible to credit (store) up to 50 medals, and the number of credited medals is displayed on the credit number display 16.

  When the start lever 17 is pressed, the first to third reels 14a to 14c start to rotate. When the stop buttons 18a to 18c are pressed, the corresponding first to third reels 14a to 14c are individually stopped.

  A medal tray 19 is provided below the front door 12. The medal is paid out from the payout slot 20 to the medal tray 19 when a winning combination involving paying out medals is performed or when a player receives a medal loan. In order to receive a medal loan, the prepaid prepaid card 40a (see FIG. 2) is inserted into the medal lending machine 40 (see FIG. 2) adjacent to the side of the slot machine 10, and the medal lending machine 41 Just press the rent button.

  A liquid crystal panel 21 is provided above the display window 13. From the liquid crystal panel 21, an effect display indicating the result of the winning combination lottery is displayed by, for example, a character or a character. As will be described in detail later, whether or not to display the effect display is determined by the effect lottery performed after the winning combination lottery. In the effect display, a single effect completed in one game and a continuous effect performed over a plurality of games are set. In the effect lottery, when the effect display is displayed, it is determined at the same time whether the single effect or the continuous effect is performed. In the slot machine 10, the continuous performance is performed over five games. Since three medals are bet in one game, 15 medals are used until the continuous performance is completed.

  As shown in FIG. 2, the operation of the slot machine 10 is controlled by the control unit 30. The control unit 30 is provided with a CPU 30a, a memory 31, and the like. The CPU 30a controls the slot machine 10 according to the game execution program stored in the ROM area of the memory 31. The RAM area of the memory 31 is used for temporary storage or rewriting of flags and data used for each game.

  The medal sensor 32 detects a medal inserted from the medal slot 15 and inputs a medal detection signal to the CPU 30a. The start signal sensor 33 detects that the start lever 17 has been pressed, and inputs a game start signal to the CPU 30a. The CPU 30a rotates the first to third reels 14a to 14c in response to the game start signal.

  The drive and stop control of the first to third reels 14a to 14c are performed by the CPU 30a and the reel drive controller 34. Each reel is attached to a drive shaft of an individual stepping motor 35a-35c, and each reel is controlled by controlling the driving of each stepping motor 35a-35c. The stop button sensors 38a to 38c input a stop signal to the CPU 30a when the stop buttons 18a to 18c are pressed. In response to the stop signal, the CPU 30a and the reel drive controller 34 start stop control of the first to third reels 14a to 14c corresponding to the stop buttons 18a to 18c.

  When a game start signal is input from the start signal sensor 33 while the first to third reels 14a to 14c are not rotating, the CPU 30a activates the winning combination determining unit 39. In the winning combination determination unit 39, one of the three types of winning combinations consisting of BB, small combination, and replay and lose is determined by lottery. Since the lottery method is a well-known method, a detailed description is omitted.

  A medal lending machine 40 is connected to the CPU 30a. When the prepaid card 40a purchased by the player is inserted into the medal lending machine 40 and the lending button is pressed, a medal lending signal is input from the medal lending machine 40 to the CPU 30a. The lending signal includes the number information indicating the number of medals lent to the player and the remaining amount information indicating the remaining amount of the prepaid card 40a. The prepaid card 40a is selected and purchased from, for example, three types of 10,000 yen, 5000 yen, and 3000 yen. Then, for each press of the lending button, 50 medals each worth 20 yen, that is, 1000 yen medals are lent to the player. Therefore, the prepaid card 40a of 10,000 yen can receive 500 medals, the prepaid card 40a of 5000 yen can receive 250 cards, and the prepaid card 40a of 3000 yen can receive a medal loan up to 150 cards. The CPU 30a writes the number of medals lent to the player in response to the lending signal in the lending number storage unit (lending number storage means) 41.

  When a game is played, the CPU 30a inputs the number of medals inserted and the number of medals paid out after playing the game to the net increase number calculation unit (net increase number calculation means) 42. The net increase number calculating unit 42 calculates the total number of medals inserted after the medals are lent and the total number of medals paid out after the medals are lent. Then, the net increase number calculation unit 42 calculates the net increase number of medals by subtracting the total insertion number of medals from the total payout number of medals. Note that the net increase is expressed as a positive number when the player's medal increases, and as a negative number when the player loses the medal.

  The remaining number calculation unit (remaining number calculation means) 43 receives the lent medal number written in the lent number storage unit 41 and the net increase number of medals calculated by the net increase number calculation unit 42. The remaining number calculation unit 43 calculates the sum of the lent number and the net increase number. Thereby, as a result of the game being played, the remaining number of medals owned by the player is calculated.

  In the effect data storage unit (effect storage means) 44, effect display graphic data to be displayed from the liquid crystal panel 21 is written. The graphic data includes data for performing a single effect and data for performing a continuous effect. The graphic data in the effect data storage unit 44 is read by the effect control unit (effect control means) 46. The effect control unit 46 displays an effect display from the liquid crystal panel 21 based on the read graphic data.

  The production lottery unit (production lottery means) 45 is operated each time the winning combination lottery is performed in the winning combination determination unit 39. The effect lottery unit 45 performs an effect lottery that determines whether or not to display an effect display. When it is determined to display the effect display, it is simultaneously determined whether to perform the single effect or the continuous effect. The effect lottery unit 45 determines whether or not to display the effect display by comparing the sampled random number value with the first effect table (effect table) 45a or the second effect table (effect table) 45b. In the second effect table 45b, the probability of effect lottery is set so that the probability that an effect display is displayed is higher than that in the first effect table 45a. For this reason, when the effect lottery is performed using the second effect table 45b, the frequency of effect display increases. As will be described in detail later, when a game is started upon receiving a medal loan, an effect lottery is first performed using the first effect table 45a. Although not shown in detail, the first effect table 45a and the second effect table 45b include a table when winning a BB, a table when winning a small role, and a table when losing, respectively. The effect display assigned to each table has a different aspect. Each table is properly used according to the winning combination lottery result. Thereby, the effect display suggests whether or not the winning combination is won.

  The effect control unit 46 receives the remaining number of medals calculated by the remaining number calculation unit 43 via the CPU 30a. In response to this, the effect control unit 46 determines whether or not the remaining number of medals owned by the player is 10 or less. When it is determined that the remaining number of medals is 10 or less, the effect control unit 46 operates the switching lottery unit (switching lottery means) 47.

  The switching lottery unit 47 performs a table switching lottery that determines whether or not the effect lottery is performed by switching the first effect table 45a to the second effect table 45b. The result of the table switching lottery is fed back to the effect control unit 46. The effect control unit 46 inputs a signal indicating either the first effect table 45a or the second effect table 45b to the effect lottery unit 45 according to the result of the table switching lottery. The effect lottery unit 45 identifies the type of table in which the effect lottery is performed in response to the signal input from the effect control unit 46.

  The hopper device 48 pays out a prescribed number of medals according to the type of winning combination, or pays out medals when a lending signal is input from the medal lending machine 40. The payout table in which the number of payout medals is determined for each type of winning combination is stored in the ROM area of the memory 31, and the CPU 30a reads this to drive the hopper device 48.

  Next, the operation of the slot machine configured as described above will be described. To play a game in the slot machine 10, the player purchases the prepaid card 40a at the game hall. Then, the purchased prepaid card is inserted into the medal lending machine 40, and the lending button is pressed. When the lending button is pressed, a lending signal is input from the medal lending machine 40 to the CPU 30a. In response to this, the CPU 30 a writes the number of medals “50” lent to the player to the rented number storage unit 41 and drives the hopper device 48. When the hopper device 48 is driven, 50 medals are paid out to the medal tray 19. When the rent button is pressed again and medals are lent to the player, the accumulated number is written in the rent number storage unit 41.

  The player plays a game using the paid-out medals. When the game is started and the winning combination lottery is performed, the effect lottery is performed using the first effect table 45a. When the effect lottery is won, the effect control unit 46 reads the graphic data from the effect data storage unit 44 and displays the effect display from the liquid crystal panel 21.

  When a game is played, the number of inserted medals and the number of paid out medals are input to the net increase number calculating section 42. The net increase number calculation unit 42 calculates the net increase number of medals. The CPU 30 a inputs the calculated net increase number to the remaining number calculation unit 43. At the same time, the CPU 30 a reads the lent number of medals from the lent number storage unit 41 and inputs the read lent number to the remaining number calculation unit 43.

  The remaining number calculation unit 43 adds up the two input numbers and calculates the remaining number of medals owned by the player (for example, the number of lent medals is “50” and the net increase is “−45”). In the case of “sheets”, the remaining number is “5”, and in the case where the number of lent medals is “50” and the net increase is “20”, the remaining number is “70”). The remaining number of medals calculated by the remaining number calculation unit 43 is input to the effect control unit 46.

  When the remaining number of medals owned by the player is 10 or less, the effect control unit 46 operates the switching lottery unit 47. The switching lottery unit 47 performs table switching lottery. When the table switching lottery is won, the effect control unit 46 inputs a signal indicating the second effect table 45 b to the effect lottery unit 45. In response to this, the effect lottery unit 45 performs an effect lottery using the second effect table 45b. Thereby, the probability that an effect display is displayed becomes higher than before the remaining number of medals becomes 10 or less. Then, if it is decided to perform the continuous production by the production lottery, 15 medals are required for the completion of the continuous production lottery. Therefore, the player finishes using the medals before the production of the continuous production is completed. become. As a result, the player is further required to receive a medal loan, so that the game can be prevented from being stopped.

  If the remaining number of medals exceeds 10 before the player continues to play the game and receives the medal loan again, the effect control unit 46 again sends a signal indicating the first effect table 45a to the effect lottery unit 45. input. In response to this, the effect lottery unit 45 performs the effect lottery again using the first effect table 45a. When the remaining number of medals becomes 10 or less, the lottery unit 47 forcibly switches from the first effect table 45a to the second effect table 45b without performing the table switching lottery in the switching lottery unit 47. May be.

  In the above embodiment, the probability that the effect display is displayed when the remaining number of medals is less than or equal to the predetermined number is increased, but the effect display is forcibly displayed when the number of medals becomes less than or equal to the predetermined number. May be.

  In this case, for example, a read lottery unit (read lottery means) 50 is provided instead of the switching lottery unit 47. As shown in FIG. 4, the read lottery unit 50 is activated when the remaining number of medals becomes 10 or less. The read lottery unit 50 performs a read lottery to determine which graphic data of the single effect or the continuous effect is read from the effect data storage unit 44. When the continuous effect is determined, the effect control unit 46 reads the graphic data of the continuous effect from the effect data storage unit 44, and causes the liquid crystal panel 21 to perform the continuous effect over five games. Since 15 medals are required to complete the continuous performance, the player finishes using the medals before the continuous performance is completed. When the remaining number of medals of the player exceeds 10, the reading of the effect data is stopped after the end of the continuous effect, and it is determined whether or not to display the effect display by effect lottery. When the single effect is determined, the effect control unit 46 reads the graphic data of the single effect from the effect data storage unit 44 and causes the liquid crystal panel 21 to perform the single effect. When the effect display is forcibly displayed, the result of the effect lottery in the effect lottery unit 45 may be canceled or the effect lottery may not be executed. In addition, a lottery for determining whether or not to display an effect display may be performed simultaneously with the readout lottery. In FIG. 4, the flow from “start” to “remaining 10 sheets or less?” Is the same as that in FIG.

  In the above embodiment, the probability that an effect display is displayed when the remaining number of medals becomes less than or equal to a predetermined number every time a player receives a medal loan is uniformly increased, but the prepaid card 40a purchased by the player When the difference between the number of medals corresponding to the amount of money and the net increase is equal to or less than the predetermined number, that is, when the remaining amount of the prepaid card 40a becomes “0” after receiving the medal loan, the effect display is further displayed. The probability of being displayed may be increased. In this case, a third effect table 51 having a higher probability of effect display being displayed than the second effect table 45b may be provided as a table used for effect lottery.

  The CPU 30 a identifies whether or not the remaining amount of the prepaid card 40 a is “0” from the remaining amount information included in the lending signal transmitted from the medal lending machine 40, and writes the identification result in the RAM area of the memory 31. .

  As shown in FIG. 5, when the remaining number of medals is 10 or less and the table switching lottery is won, the CPU 30a refers to the RAM area of the memory 31 and determines whether or not the remaining amount of the prepaid card 40a becomes “0”. To identify. When identifying that the remaining amount of the prepaid card 40a is “0”, the CPU 30a inputs a signal indicating that the remaining amount is “0” to the effect control unit 46. In response to this, the effect control unit 46 switches from the first effect table 45a to the third effect table 51 and causes the effect lottery unit 45 to perform the effect lottery. Thereby, the player can be prompted to purchase a new prepaid card 40a. When the remaining amount of the prepaid card 40a is not “0”, the effect control unit 46 switches from the first effect table 45a to the second effect table 45b and causes the effect lottery unit 45 to perform effect lottery. In FIG. 5, “Start” to “Winning” are the same as those in FIG.

  In the above embodiment, an effect display is displayed from the liquid crystal panel 21 as an effect, but the effect may be performed by an appropriate means such as a voice or a lamp.

  Note that the present invention is not limited to a reel drive type slot machine, and can be equally applied to other gaming machines such as a slot machine using a liquid crystal panel. Further, as in the above-described embodiment, the present invention is not limited to a gaming machine having a total of five winning active lines, that is, three horizontal lines and two diagonal lines. is there.

It is an external view of the slot machine using the present invention. FIG. 2 is a functional block diagram showing an electrical schematic configuration of the slot machine shown in FIG. 1. It is a flowchart which shows the flow of control until the probability that an effect display is displayed changes. It is a flowchart which shows the flow of control until an effect display is forcibly displayed. It is a flowchart which shows the flow of control in the case of changing the probability that an effect display is displayed when the remaining amount of a prepaid card becomes "0".
