Description

  The present invention relates to a gaming machine configured to extract a random number in order to determine a symbol aspect that is permitted to be displayed when symbol fluctuation is stopped and that indicates a game result.

  Conventionally, in a slot machine using medals (coins) as game media, when 1 to 3 medals are inserted and the start lever is operated, the game starts and three sets of reels start rotating. A plurality of symbols marked on the outer peripheral surface are displayed in a variable manner, and then the game ends when the three reels stop rotating. When the three reels stop rotating, the displayed combination of symbols (symbol mode) is, for example, any one of the lost mode, the winning mode, the replay mode, and the special winning mode, and the game result is shown.

  In this type of slot machine, various processes (game control) are performed by the control device. In the random number extraction process, a random number is normally obtained when a start switch is operated by operating a start lever with a medal inserted. Random numbers generated in the generator are extracted. Thereafter, in the symbol determination process, based on the random number extracted in the random number extraction process, a symbol aspect that is allowed to be displayed when the variation of the symbol is stopped and indicates a game result is determined, and then determined in the symbol determination process. The three reels are controlled to stop so that the displayed symbol form is stopped.

  Normally, the wait time is counted from the start of reel rotation in each game, and when the start switch is activated, the wait time from the start of the previous reel rotation is less than the set time (for example, 4.1 seconds). Is in a standby state immediately without starting the rotation of the reel, and when the set time has elapsed, the rotation of the reel is started. Here, a slot machine in which the random number generated by the random number generation unit is extracted not at the time when the start switch is operated but at the time of starting the reel rotation is also well known.

  On the other hand, in a pachinko machine using a game ball (pachinko ball) as a game medium, a game ball is continuously fired on a game board having a number of obstacle nails and winning holes to play a game. In addition, on pachinko machines with a game board with a start opening, symbol display, and special prize opening, the random number generated by the random number generator when the game ball enters the start opening and the start switch operates Are extracted, and the symbol form is determined based on the random number. That is, after a plurality of symbols are variably displayed on the symbol display, the symbol display is controlled so that the symbol mode is stopped and displayed when the variation is stopped.

  By the way, in a conventional gaming machine such as a slot machine or a pachinko machine, the random number extracted when the start switch is operated is not simply used to determine the symbol form that is permitted to be displayed when the symbol fluctuation is stopped. A technique is generally used in which a predetermined calculation is performed using a plurality of random numbers acquired from different random number generators as the random numbers, and the numerical values obtained as a result are used.

For example, Patent Document 1 discloses a slot machine that calculates a random number for lottery by adding a soft random number obtained by adding a certain number at predetermined timings to a hard random value that sequentially counts clock pulses. The timing for extracting the hard random value and the soft random value is when the start lever is operated, as in a general technique.

  In the conventional slot machine, when the start lever is operated with the medal inserted, the start switch is activated, and when the start switch is activated, the random number generated by the random number generator is extracted. Even if a predetermined calculation is performed using the extracted random number and the numerical value obtained as a result is used for design determination, the periodicity of the extracted random number is predicted and a sensory device or the like is used. There is a possibility that the start lever (start switch) can be operated so that a specific random number from which an intentionally advantageous game result can be obtained is extracted.

  In particular, when the start lever is operated, if the wait time from the start of the previous reel rotation is less than the set time, a so-called wait is applied, and when the set time elapses, the reel starts rotating and a random number In the slot machine that extracts random numbers generated in the generator, if you operate the start lever so that it takes a weight, this random number extraction time will be a fixed time after a certain wait time elapses from the previous random number extraction time, Using this wait time, for example, there may be a possibility of extracting a specific random number for which a deliberately advantageous game result can be obtained by weighting several times continuously.

  In addition, pachinko machines require a little advanced technology, but a game ball enters the start port so that a specific random number that can be used to achieve a deliberately advantageous game result is extracted by using a sensory device. There is a possibility that the game ball can be launched onto the game board so as to activate the start switch.

  The object of the present invention is to provide a delay time based on the wait time measured from the predetermined time related to the previous symbol variation acquired when the start switch is operated, and further on the basis of the random number acquired from the second random number generator. The random number generated by the random number generation means at the time based on this delay time is extracted at random, making the periodicity of the extracted random numbers unpredictable and deliberately advantageous using a sensory device etc. It is an object of the present invention to provide a gaming machine that can surely prevent a fraud in which a specific random number from which a game result is obtained can be extracted.

The gaming machine according to claim 1, wherein the symbol variation means for variably displaying a plurality of symbols, the variation start means for starting the symbol variation by the symbol variation means when the start switch is actuated, and the symbol variation are stopped. a change stop means, a random number generation means, and a random number extracting means for extracting a random number generated by said random number generating means for determining a symbol mode shown a a and a game result in symbol mode of display permission when fluctuations stop symbol In the gaming machine provided, when the start switch is operated , the random number extracting means is a wait time acquiring means for acquiring a wait time measured from a predetermined time related to a previous symbol variation, and the start switch is operated. a delay time determining means for determining a random delay time based on the weight the wait time obtained by the time obtaining means when the start switch When the delay time from the time of operation of has passed, characterized in that a random number acquisition means for acquiring a random number generated by said random number generation means.

In this gaming machine, when the start switch is actuated, the variation start means starts symbol variation by the symbol variation means, and the random number extraction means permits display when the symbol variation is stopped. Random numbers generated by the random number generation means are extracted to determine the symbol form indicating the game result. In this random number extraction means, when the start switch is operated by the wait time acquisition means , the wait time measured from the predetermined timing related to the previous symbol variation is acquired , and the start switch is operated by the delay time determination means The delay time is randomly determined based on the wait time, and the random number generation unit acquires the random number generated by the random number generation unit when the delay time has elapsed since the start switch is operated. Based on the random numbers extracted in this way, a symbol mode that is allowed to be displayed when symbol variation is stopped and that indicates a game result is determined.

About the gaming machine of Claim 1, the following structure is employable.
The delay time determination means performs a predetermined operation to determine the delay time and using a random number obtained from the second random number generating means and the wait time (Claim 2). Applied to a slot machine provided with start-up operation means to be operated for actuating the start switch (claim 3).

  According to the gaming machine of claim 1, in particular, in the random number extracting means for extracting the random number generated by the random number generating means in order to determine the symbol aspect that is permitted to be displayed when the fluctuation of the symbol is stopped and that shows the game result. The delay time determining means randomly determines the delay time when the start switch is operated, and the random number acquisition means is used to obtain the random number generated by the random number generating means when the delay time has elapsed since the start switch is operated. Since it is acquired, the periodicity of the extracted random numbers can be made unpredictable, and it is possible to reliably prevent fraud in which specific random numbers from which a deliberately advantageous game result can be obtained are intentionally extracted using a sensory device or the like. it can.

The random number extracting means has a wait time acquiring means for acquiring a wait time measured from a predetermined time related to the previous symbol variation when the start switch is operated, and the delay time determining means is the wait time acquiring means. Since the delay time is determined based on the wait time acquired in (1), the delay time can be determined more randomly, and the periodicity of the extracted random numbers can be made more unpredictable. Note that the predetermined time is, for example, the previous time when the symbol variation starts. Here, the delay time determining means can be configured to determine the delay time within a range from when the start switch is operated to when the symbol variation related to the operation is started. The symbol change start is not sent. That is, since the random number is acquired when the variation of the symbol is started as usual, it is possible to produce an effect related to the random number lottery result together with the start of the variation of the symbol.

According to the gaming machine of claim 2 , the delay time determining means determines the delay time by performing a predetermined calculation using the random number acquired from the second random number generating means and the wait time. The randomness can be determined more randomly, and the periodicity of the extracted random numbers can be made more unpredictable.

According to the gaming machine of the third aspect , since the present invention is applied to the slot machine provided with the start operation means for operating the start switch, the player can operate the start switch by operating the start operation means. Can do. At this time, the player can actuate the start switch at any time, but as described above, since this game machine can make the periodicity of the extracted random numbers unpredictable, such as a bodily sensation machine, etc. By using this, it is possible to reliably prevent fraud in which a specific random number from which a deliberately advantageous game result is obtained is targeted.

The delay time determining means 66 performs a predetermined calculation using the random number acquired from the second random number generating means 68 and the wait time tw, and from the time when the start SW 35a is operated, The delay time Td is determined within the range until the fluctuation starts.

  Here, in the case of the present embodiment, the symbol variation means 60 corresponds to the reel unit 53, and includes a variation start means 61, a variation stop means 62, a wait time acquisition means 65, a delay time determination means 66, and a random number acquisition means 67. The random number extraction means 64 and the means for measuring the wait time tw are included in a microcomputer provided on the main control board 50.

Next, game control executed by the microcomputer provided on the main control board 50 will be described with reference to FIGS.
As shown in FIG. 5, this game control is started when the power is turned on, and after initial setting, the process proceeds to S1. In S1, the RAM data for each game is cleared, and then the medal insertion process (S2) is executed. When three medals are inserted, the start lever 35 is operated and the start SW 35a is activated (turned on). The random number extraction process (S3) is executed, and the symbol lottery process (S4) is executed based on the random number extracted by the random number extraction process, and the display is permitted when the change of the symbol is stopped, and the game result is shown. The symbol pattern is determined by lottery.

  Thereafter, a reel rotation start process (S5) is executed, and the rotating reels 3 to 5 start rotating. In this reel rotation start process, the wait time tw is counted from the start of reel rotation. If the wait time tw from the start of the previous reel rotation is less than a set time (eg, 4.1 seconds). Immediately, the rotation of the rotating reels 3 to 5 is not started, but a standby state is set, and when the set time has elapsed, the rotation of the rotating reels 3 to 5 is started.

  Thereafter, after the rotation speeds of all the reels 3 to 5 become constant and the operation of the stop buttons 36 to 38 becomes effective, the stop buttons 36 to 38 are operated and the stop SWs 36 a to 38 a are activated (turned on). Then, reel rotation stop processing (S6) is executed. In this reel rotation stop process, the reel units 53 (drive motors 3a to 5a) are stopped so that the rotation reels 3 to 5 stop rotating in a state in which the symbol form determined in the symbol lottery process of S4 is displayed on the display window 15. ) Is controlled. Next, a winning determination process (S7) is executed to determine whether or not the symbol form displayed on the display window 15 is a prize, and the number of medals to be paid out according to the type of symbol aspect is set. The medal payout process (S8) is executed.

  Here, all design modes that can be stopped and displayed on the display window 15 are classified into a loss mode, a winning mode, a replay mode, an RB mode, and a BB mode, and the winning mode, the RB mode, and the BB mode are winning modes. When these modes are stopped and displayed on the display window 15, medals can be obtained. Next, when the symbol mode displayed on the display window 15 is the replay mode and the replay winning (S9; Yes), the replay operation start process (S10) is the RB mode and the RB winning (S11; Yes). ), When the RB operation start processing (S12) is the BB mode and the BB winning is achieved (S13; Yes), the BB operation start processing (S14) is executed, and then the process returns to S1.

  In addition, when it is not a replay, RB, or BB winning (S9; No, S11; No, S13; No), and next, when an RB is operating (S15; Yes), an RB operating process (S16). ) Is executed, and then the process returns to S1, and when the RB is not operating (S15; No), when the BB is operating (S17; Yes), the BB operating process (S18) is executed, and BB If it is not in operation (S17; No), the process returns to S1. After S18, if the BB operation is not finished (S19; No), the process returns to S1, but if the BB operation is finished (S19; Yes), the RAM data for each BB end is cleared (S20), and the process returns to S2.

Next, the random number extraction process in S3 will be described.
As shown in FIG. 6, when the random number extraction process is started, first, a game timer value YT corresponding to the wait time tw counted from the previous reel rotation start time is acquired (S30). Here, when the wait time tw reaches a set time (for example, 4.1 seconds), the game timer value YT becomes zero. Next, it is determined whether or not the game timer value YT acquired in S30 is 0 (S31). If YT = 0 (S31; Yes), that is, the set time has elapsed since the start of the previous reel rotation. In this case, the random number acquisition calculation process (S37) is immediately executed.

  On the other hand, if YT = 0 is not satisfied (S31; No), that is, if the set time has not elapsed since the start of the previous reel rotation, then the random number RNDA generated by the second random number generation means 68 is acquired. (S32). Then, the game timer value YT acquired in S30 and S32 is compared with the random number RNDA (S33). Therefore, if [game timer value YT> random number RNDA] is not satisfied (S33; No), [random number RNDA-game timer value YT] is calculated, the calculated value is set to random number RNDA, and random number RNDA is updated (S34). .

  If S33; No, S34 is repeatedly executed. If [Game Timer Value YT> Random Number RNDA] (S33; Yes), then [Game Timer Value YT-Random Number RNDA] is calculated and delayed. A timer value corresponding to time is set in a delay timer CT which is a subtraction timer (S35). Immediately after that, the delay timer CT is subtracted. Thereafter, when the delay timer CT becomes 0 (S36; Yes), a random number acquisition calculation process (S37) is executed.

  Thus, as shown in FIG. 7, when the start SW 35a is turned on and the wait time tw counted from the previous reel rotation start is not the set time (4.1 seconds), the current start SW 35a The delay time Td is calculated within the range from the start of operation to the start of the fluctuation of the reels 3 to 5 related to the operation, and when the delay time Td elapses from when the start SW 35a is turned on, a random number is acquired in S37. Will be.

  Next, the random number acquisition calculation process of S37 will be described. First, the random number generation means 63 will be described. This random number generating means 63 is generated while updating a hard random number generating means comprising an IC counter that is generated while updating a 2-byte hard random number, and a 2-byte soft random number (lottery addition random number) by a timer interrupt process of a computer. Soft random number generation means. For example, the update cycle of hard random numbers is 0.167 μs, and the update cycle of soft random numbers is 1.493 ms.

  Now, as shown in FIG. 8, when the random number acquisition calculation process of S37 is started, the lower byte of the generated hard random number is acquired (S40), and the lower byte data is the lower order of the lottery random number data. The upper byte of the generated hard random number is acquired (S42), and the upper byte data is set as the upper byte of the lottery random number data (S43). Subsequently, the generated random number for lottery occurrence is acquired (S44), and the value of the R register of the CPU is acquired (S45).

  Next, the value of the acquired R register is doubled (S46), 1 is added to the value (S47), the value is set to the lower byte of the 2-byte addition data (S48), and 0 is added. It is set in the upper byte of the data (S49). Next, the addition data set in S48 and S49 is added to the lottery addition random number acquired in S44 (S50), and then the lottery addition data set in S41 and S43 is added to the value. (S51).

  Next, the upper byte of the value obtained in S51 is masked (S52), the value is set as the upper byte of the lottery random number data (S53), and the lottery random number data is written in the lottery random number (S54). , Return to S4. Based on the random numbers for lottery thus calculated, the symbol lottery process of S4 is calculated, and the symbol mode which is allowed to be displayed when the symbol fluctuation is stopped and which shows the game result is determined by lottery.

The slot machine 1 described above has the following effects.
In the random number extraction means 64 for extracting the random number generated by the random number generation means 63 in order to determine the design aspect that is permitted to be displayed when the fluctuation of the symbols is stopped and that shows the game result, the delay time determination means 66 causes the start SW 35a. When the delay time Td is randomly determined, the random number acquisition unit 67 acquires the random number generated by the random number generation unit 63 when the delay time Td has elapsed since the start SW 35a is operated. Therefore, it is possible to reliably prevent fraud in which a specific random number from which a deliberately advantageous game result can be obtained is aimed and extracted by using an sensation machine or the like.

  The random number extraction means 64 has wait time acquisition means 65 for acquiring the wait time tw measured from the previous symbol change time when the start SW 35a is operated, and the delay time determination means 66 is a wait time acquisition means. Since the delay time Td is determined based on the wait time tw acquired at 65, the delay time Td can be determined more randomly, and the periodicity of the extracted random numbers can be made more unpredictable. Here, the delay time determining means 66 calculates the delay time Td within the range from the time when the start SW 35a is operated to the time when the fluctuations of the reels 3 to 5 related to the operation start. Does not cause the reels 3 to 5 to start moving. That is, since the random number is acquired when the fluctuations of the reels 3 to 5 are started as usual, it is possible to perform an effect related to the random number lottery result together with the start of the fluctuations of the reels 3 to 5.

  Further, the delay time determining means 66 performs a predetermined calculation using the random number acquired from the second random number generating means 68 and the wait time tw to determine the delay time Td, so that the delay time is determined more randomly. In addition, the periodicity of the extracted random numbers can be made more unpredictable. In addition, as shown in FIG. 8, the lottery random number necessary for determining the symbol mode that is finally permitted to be displayed when the symbol variation is stopped and that indicates the game result is the hard random number acquired as the random number. In addition, since the soft random number and the value of the R register of the CPU are further calculated and determined, it is possible to reliably prevent an illegal act of intentionally extracting a specific random number from which a deliberately advantageous game result is obtained.

  In the slot machine 1 provided with the start lever 35 corresponding to the start operation means operated to operate the start SW 35a as in this embodiment, the player operates the start SW 35a by operating the start lever 35. be able to. At this time, the player can operate the start SW 35a at any timing, but as described above, the slot machine 1 can make the periodicity of the extracted random numbers unpredictable. By using a machine or the like, it is possible to reliably prevent fraud in which a specific random number from which a deliberately advantageous game result is obtained is aimed at.

  Note that various calculations other than the present embodiment can be employed for the calculation for determining the delay time Td. For example, in S34 of FIG. 6, instead of [RNDA-YT → RNDA], [YT → RNDA] may be used. Also, the timing for starting the delay time measurement need not be the time of the start of symbol fluctuation. For example, when any of the stop SWs 36a to 38a is activated when the previous start SW 35a is activated, If acquired, the medal can be set at various predetermined times related to the previous symbol variation, such as when the medal is paid out or stored.

In the second embodiment, the random number extraction process is partially changed in the slot machine 1 of the first embodiment. Note that the same reference numerals as those in Embodiment 1 are used for explanation.
As shown in FIG. 9, when the random number extraction process is started, first, a game timer value YT corresponding to the wait time tw counted from the previous reel rotation start time is acquired (S60). The random number RNDA generated by the second random number generation means 68 is acquired (S61).

  Next, it is determined whether or not the game timer value YT acquired in S60 is 0 (S62). If YT = 0 (S62; Yes), the same random number acquisition calculation process (S68) as S37 is immediately executed. On the other hand, if YT = 0 is not satisfied (S62; No), the game timer value YT acquired in S60 and S61 is compared with the magnitude of the random number RNDA (S63). Therefore, if [game timer value YT> random number RNDA] is not satisfied (S63; No), [random number RNDA-game timer value YT] is calculated, the calculated value is set in random number RNDA, and random number RNDA is updated (S64). .

  S63; If No, S64 is repeatedly executed. If [Game timer value YT> Random number RNDA] (S63; Yes), then the random number RNDA is set to the determination timer value HT corresponding to the determination time. (S65). Thereafter, the game timer value YT is acquired (S66), and then it is determined whether or not the game timer value YT acquired in S66 is the same as the determination timer value HT set in S65 (S67). . If it is not [game timer value YT = determination timer value HT] (S67; No), S66 and S67 are repeatedly executed until S67; Yes.

  Thereafter, when [game timer value YT = determination timer value HT] is reached (S67; Yes), the same random number acquisition calculation processing (S68) as S37 is executed. Thus, as shown in FIG. 10, when the start SW 35a is turned on, when the wait time tw counted from the previous reel rotation start is not the set time (4.1 seconds), the start SW 35a is activated. A delay time corresponding to the determination time from when the start SW 35a is turned on, and from the time when the start SW 35a is operated this time, the reels 3 to 5 related to the operation are calculated. When a delay time within a range until the change is started, [game timer value YT = determination timer value HT] is obtained, and a random number is acquired in S68. According to this slot machine 1, the same effects as those of the first embodiment are obtained.

  Note that various calculations other than the present embodiment can be employed for the calculation for determining the determination time. For example, in S64 of FIG. 9, instead of [YT → RNDA], [RNDA-YT → RNDA] may be used. Also, the timing for starting the delay time measurement need not be the time of the start of symbol fluctuation. For example, when any of the stop SWs 36a to 38a is activated when the previous start SW 35a is activated, If acquired, the medal can be set at various predetermined times related to the previous symbol variation, such as when the medal is paid out or stored.

The present invention is applied to a pachinko machine using a game ball (pachinko ball) as a game medium.
Although not shown, the pachinko machine is provided with a game board that sequentially fires game balls, and a number of obstacle nails, a winning opening, a starting opening, a symbol display, and a special winning opening are provided in the gaming area. . The symbol display corresponds to symbol variation means that displays multiple symbols variably, the proximity switch provided at the start port corresponds to the start switch, and when the game ball enters the start port, the start switch is activated and the symbol display The design changes by the instrument.

  The symbol display and the start switch are connected to a control device provided inside the pachinko machine, and by this control device, the fluctuation start means, fluctuation stop means, random number generation means, wait time acquisition time and delay time determination means, Random number extraction means having random number acquisition means is configured. In this pachinko machine, when the start switch is activated by entering the start port during symbol variation (when there is a later-described suspension), the symbol variation related to the operation is suspended, for example, up to four times. The reserved symbol variation is sequentially executed after the current symbol variation including the previously reserved symbol variation is completed.

  Here, when the start switch is operated in the case of the hold, in the random number extraction means, for example, the remaining time of the current symbol variation is acquired, and the delay time determination means is held based on the remaining time. The delay time is determined within the range until the symbol variation starts (for example, within the remaining time), and the random number acquisition means is generated by the random number generation means when the delay time has elapsed since the start switch was activated. Get random number. In such a pachinko machine, the same operations and effects as described above are achieved.
