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, in 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. In general, a technique is used in which a predetermined calculation is performed using a plurality of random numbers acquired from different random number generators as the random number, and a numerical value obtained as a result is used for design determination. .

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.
JP 2003-126333 A

  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 acquire a first random number when the first predetermined condition resulting from the activation of the start switch is established, and to obtain the first random number when the second predetermined condition resulting from the establishment of the first predetermined condition is satisfied. The second random number can be acquired at a timing different from that of the first random number, and a predetermined calculation is performed using the first and second random numbers, and a symbol lottery value for determining a symbol aspect that is permitted to be displayed when the symbol variation is stopped. It is to provide a gaming machine that can reliably prevent a fraud in which a specific random number from which a deliberately advantageous game result is obtained is intentionally obtained by using a sensory device or the like.

  The gaming machine according to claim 1 includes a symbol changing means for variably displaying a plurality of symbols, a change starting means for starting a symbol change by the symbol changing means when the start switch is operated, and a change for stopping the symbol change. A stop means, a random number generation means, and a random number extraction means for extracting a random number generated by the random number generation means to determine a design aspect that is permitted to be displayed when the fluctuation of the design is stopped and that indicates a game result. In the gaming machine, the random number generation means includes a first random number generation means and a second random number generation means, and the random number extraction means is provided when a first predetermined condition resulting from activation of the start switch is satisfied.

  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. This random number generating means has a first random number generating means and a second random number generating means. In the random number extracting means, the first predetermined condition resulting from the start switch being activated is established by the first random number acquiring means. When the first random number generated by the first random number generation means is acquired and the second predetermined condition resulting from the establishment of the first predetermined condition is satisfied by the second random number acquisition means, the first random number acquisition means The second random number generated by the second random number generation means is acquired at a timing different from the random number acquisition timing. Then, the symbol lottery value calculation means performs a predetermined calculation using the first and second random numbers acquired by the first and second random number acquisition means to determine the symbol lottery value. Based on the symbol lottery value determined in this way, the symbol mode that is allowed to be displayed when the symbol variation is stopped and that indicates the game result is determined.

About the gaming machine of Claim 1, the following structure is employable.
When the start switch is actuated, when the set time has not elapsed since the predetermined time related to the previous symbol variation, the symbol variation is configured to start after the set time has elapsed, and the first predetermined condition and Is that the start switch has been operated, and the second predetermined condition is that the set time has elapsed (Claim 2). The update cycle of the first random number generated by the first random number generator is different from the update cycle of the second random number generated by the second random number generator. The present invention is applied to a slot machine provided with start operation means for operating the start switch.

  According to the gaming machine of claim 1, in particular, the first and second random number generation means are provided as the random number generation means, and the symbol aspect that allows the display when the fluctuation of the symbol is stopped and that shows the game result is determined. In the random number extraction means for extracting the random number generated by the random number generation means, the first random number generation means generates the first random number generation means when the first predetermined condition resulting from the activation of the start switch is satisfied by the first random number acquisition means The first random number is acquired, and when the second predetermined condition resulting from the establishment of the first predetermined condition is satisfied by the second random number acquiring means, the second random number is generated at a timing different from the random number acquisition timing by the first random number acquiring means The second random number generated by the means is acquired, the symbol lottery numerical calculation means performs a predetermined calculation using the first and second random numbers acquired by the first and second random number acquisition means, and when the symbol fluctuation is stopped display Since the symbol lottery value for determining the allowed symbol mode is determined, the process for determining the symbol lottery value can be very complicated, and the symbol lottery value obtained can be made unpredictable. Therefore, it is possible to reliably prevent fraud in which a specific random number from which a deliberately advantageous game result is obtained is intentionally extracted using a sensory device or the like.

  According to the gaming machine of claim 2, when the start switch is operated, if the set time has not elapsed since the predetermined time related to the previous symbol variation, the symbol variation starts after the set time has elapsed. The first predetermined condition is that the start switch is operated, and the second predetermined condition is that the set time has elapsed. Therefore, when the start switch is operated, the first random number acquisition means performs the first operation. A random number is acquired, and the second random number can be acquired by the second random number acquisition means when the set time has elapsed. That is, the first random number and the second random number can be reliably acquired at different timings.

  According to the gaming machine of claim 3, since the update cycle of the first random number generated by the first random number generator is different from the update cycle of the second random number generated by the second random number generator, the pattern obtained by calculation It is more difficult to predict a lottery value, and it is possible to more surely prevent fraud in which a specific random number from which a deliberately advantageous game result is obtained is targeted.

  According to the gaming machine of claim 5, 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 operate the start switch at any timing, but as described above, the first and second random numbers are acquired at different timings, and the first and second random numbers are used to obtain a predetermined number. Since the numerical value for symbol lottery is determined by performing the calculation, it is possible to reliably prevent fraud in which a specific random number from which a deliberately advantageous game result is obtained is intentionally extracted using a sensory device or the like.

  As shown in FIG. 4, in the slot machine 1, the symbol variation means 60 for variably displaying a plurality of symbols and the symbol variation by the symbol variation means 60 triggered by the start switch 35a being a start switch are activated. In order to determine a symbol mode that indicates a game result, the variation starting unit 61 to start, the variation stopping unit 62 to stop the symbol variation, the random number generating unit 63, and the symbol mode to be displayed when the symbol variation is stopped. And random number extraction means 64 for extracting random numbers generated by the random number generation means 63.

  The random number generation means 63 includes a first random number generation means 63a and a second random number generation means 63b. The random number extraction means 64 has a first predetermined condition established when the start SW 35a is activated. Random number acquisition timing by the first random number acquisition means 64a when the first random number acquisition means 64a for acquiring the first random number generated by the random number generation means 63a and the second predetermined condition resulting from the establishment of the first predetermined condition are satisfied.

There is provided symbol lottery value calculation means 65 for performing a predetermined calculation using a random number and determining a symbol lottery value for determining a symbol mode to be allowed to be displayed when the symbol fluctuation is stopped.

  Here, in the case of the present embodiment, the first predetermined condition is that the start SW 35a is operated, and the second predetermined condition is the rotating reels 3 to 5 (specifically, any one of the rotating reels 3 to 5). Has started rotation and symbol variation has started, and the update cycle of the first random number generated by the first random number generator 63a and the update cycle of the second random number generated by the second random number generator 63b, Are configured differently. Further, when the start SW 35a is activated, a set time (for example, 4.1 seconds) has elapsed since a predetermined time related to the previous symbol variation (in the present embodiment, when the rotation of the previous rotating reels 3 to 5 is started). If not, the rotation of the rotary reels 3 to 5 is started after the set time has elapsed, and the symbol variation is started.

  The symbol changing means 60 corresponds to the reel unit 53, and also includes a change starting means 61, a change stopping means 62, a random number generating means 63 having first and second random number generating means 63a and 63b, and first and second random numbers. The random number extraction means 64 having the acquisition means 64a and 64b and the random number value calculation means for symbol lottery are included in the main control board 50 (mainly a microcomputer).

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. 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 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, when the random number extraction process starts, that is, when the start SW 35a is activated, the first random number generated by the first random number generation means 63a is acquired. Then, the game timer value YT measured from the start of the previous reel rotation is acquired (S31). This game timer value YT is a value obtained from a timer that is set and subtracted by setting a set timer value corresponding to a set time (for example, 4.1 seconds) at the start of the previous reel rotation.

  Next, it is determined whether or not the game timer value YT acquired in S31 is 0 (S32). If it is not 0 (S32; No), the process returns to S31, and if it is 0 (S32; Yes), that is, the previous time When the set time has elapsed since the start of reel rotation (when it has elapsed), the second random number generated by the second random number generation means 63b is acquired (S33), and then the first random number acquired in S30 and S33 Using the acquired second random number, the symbol lottery numerical calculation process (S34) is executed.

  Here, the first random number generation means 63a is a soft random number generation means that generates a 2-byte soft random number (lottery addition random number) by updating the timer interruption process of the computer, and the second random number generation means 63b This is a hard random number generation means comprising an IC counter that is generated while updating the hard random number of bytes. 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.

  That is, as shown in FIG. 7, when the start SW 35a is activated before the set time has elapsed since the start of the previous reel rotation, a soft random number (first random number) is generated when the start SW 35a is activated (on). When the set time elapses and the reels 3 to 5 start rotating, a hard random number (second random number) is acquired, and a symbol lottery value is calculated using the soft random number and the hard random number. The

  In the symbol lottery numerical calculation process of S34, as shown in FIG. 8, the lower byte data of the 2-byte hard random number (second random number) acquired in S33 is set as the lower byte of the lottery random number data. (S40), the upper byte data is set as the upper byte of the random number data for lottery (S41). Next, the value of the R register of the CPU is acquired (S42), the value of the R register is doubled (S43), 1 is added to the value (S44), and the value is the lower order of the 2-byte addition data. The byte is set (S45), and 0 is set in the upper byte of the added data (S46).

  Next, the addition data set in S45 and S46 is added to the soft random number (first random number) which is the lottery addition random number acquired in S30 (S47), and then the value is added in S40 and S41. The set lottery addition data is added (S48). Next, the upper byte of the value obtained in S48 is masked (S49), the value is set as the upper byte of the random number data for lottery (S50), and the random number data for lottery is written in the numerical value for symbol lottery (S51). ). Thus, the symbol lottery value for determining the symbol mode is determined in the symbol lottery process of S4.

The slot machine 1 described above has the following effects.
In the random number extraction means 64, the first random number acquisition means 64a acquires the first random number generated by the first random number generation means 63a when the first predetermined condition resulting from the activation of the start SW 35a is satisfied, When the second predetermined condition resulting from the establishment of the first predetermined condition is satisfied by the second random number acquiring means 64b, the second random number generating means 63b generates the second predetermined condition generated at a timing different from the random number acquisition timing by the first random number acquiring means 64a. 2 random numbers are obtained, and the symbol lottery numerical calculation means 65 performs a predetermined calculation using the first and second random numbers acquired by the first and second random number acquisition means 64a and 64b, and is displayed when the fluctuation of the symbols is stopped. Since the symbol lottery value for deciding the allowed symbol form is determined, the process for determining the symbol lottery value can be very complicated, and the symbol lottery value to be obtained can be predicted. It is possible to disable, using experience machine or the like, the illegal to extract aimed at specific random favorable game result intentionally obtain prevented reliably.

  Since the first predetermined condition is that the start SW 35a is operated, when the start SW 35a is operated, the first random number acquisition means 64a acquires the first random number, and the second predetermined condition is that the rotating reels 3 to 5 are Since the symbol variation starts after the rotation is started, the second random number acquisition means 64b can acquire the second random number when the rotating reels 3 to 5 start rotating. Then, when the set SW has not elapsed since the start of the previous reel rotation when the start SW 35a is activated, the rotating reels 3 to 5 are configured to start rotating after the set time has elapsed. When the start SW 35a is activated, the first random number and the second random number can be reliably acquired at different timings.

  Since the update cycle of the first random number generated by the first random number generator 63a and the update cycle of the second random number generated by the second random number generator 64a are different, as shown in FIG. The symbol lottery value required to determine the symbol mode that is permitted to be displayed at the time of fluctuation stoppage and indicates the game result is calculated using the obtained hard random number and soft random number, and further the value of the R register of the CPU. Therefore, it is more difficult to predict the symbol for drawing lottery obtained by calculation, and it is possible to more reliably prevent fraud in which a specific random number from which a deliberately advantageous game result is obtained is aimed at. .

  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 acquires the first and second random numbers at different timings, and the first and second random numbers are obtained. Since the calculation of FIG. 8 is performed using a random number and the symbol lottery value is determined, it is possible to reliably prevent a fraud in which a specific random number from which a deliberately advantageous game result is obtained is intentionally extracted using a sensory device or the like.

In addition, you may change as follows.
1] The first condition may be that a predetermined time has elapsed since the start switch was activated. In this case, the predetermined time may be determined at random based on the wait time tw, a random number acquired from a random number generator provided separately, or the like.
2] The second condition may be that a predetermined time has elapsed since the first random number was acquired. In this case, the predetermined time may be determined at random based on the wait time tw, a random number acquired from a random number generator provided separately, or the like.

3] The update cycle of the first random number generated by the first random number generator and the update cycle of the second random number generated by the second random number generator may be the same. Further, the first random number generation means may be a hard random number generation means and the second random number generation means may be a soft random number generation means. Moreover, both the first and second random number generation means may be hard random number generation means, or both may be soft random number generation means.
4] Regarding the calculation method in the symbol lottery numerical calculation means 65, the calculation method of FIG. 8 is merely an example, and various calculation methods can be applied.

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 random number generation means having the fluctuation start means, the fluctuation stop means, and the first and second random number generation means, Random number extraction means having first and second random number acquisition means and symbol lottery value calculation means are 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 in the case of holding is operated, a first predetermined condition is satisfied. At this time, the first random number acquisition unit acquires the first random number generated by the first random number generation unit, and then the start The second predetermined condition is established at the start of symbol variation related to the operation of the switch. At this time, the second random number acquisition unit acquires the second random number generated by the second random number generation unit, and the symbol lottery numerical calculation unit calculates the second random number. A predetermined calculation is performed using the first and second random numbers acquired by the first and second random number acquisition means, and a symbol lottery value for determining a symbol mode that is permitted to be displayed when the symbol variation is stopped is determined. In such a pachinko machine, the same operations and effects as described above are achieved.
