Description

  The present invention relates to a gaming machine such as a slot machine or a pachinko machine.

  Amusement machines can only be installed in pachinko halls if they are not suitable for inspection by inspection institutions. In addition, the gaming machine-related rules have the following rules regarding, for example, the launching of a slot machine in a live test, and only slot machines that comply with these rules are allowed to be installed in pachinko halls.

(1) After turning on the rotating device for each setting and the specified number, the test for operating the rotation stopping device at an arbitrary time was performed 400 times in an arbitrary order for all rotating rotating devices. In some cases, the total number of game medals and the like to be acquired is less than three times the total number of game medals and the like that have been inserted.
(2) When the test specified in (1) is performed 6,000 times for each setting and each specified number, the total number of game medals acquired is 1.5 times the total number of inserted game medals. Must be less than
(3) When the test specified in (1) is performed 17,500 times for each setting and every specified number, the total number of game medals to be acquired is 11 / 20th of the total number of inserted game medals etc. And less than 1.2 times.
(4) For each setting and each specified number, when the test specified in (1) is performed 6,000 times, the ratio of the number of game medals obtained, etc. due to the action of an accessory (hereinafter referred to as an accessory ratio Or, the ratio of roles) shall not exceed 70% (60% if the ratio of the first type special action is activated (hereinafter referred to as the combined ratio or combined ratio)).

  “Rules” in the rules of (4) are defined as “special equipment for facilitating winnings”. Currently, “Type 1 Special Items” and “Type 2 Special Items” In addition, it is permitted to mount three types of “normal” items on the slot machine. In addition, with regard to the “first type special feature” and the “second type special feature”, it is permitted to mount a “special feature continuous operation device” capable of continuously operating each feature. In general, the “actual accessory continuous actuating device” that can operate the “first type special feature” continuously operates the BB (big bonus) and the “second type special feature” continuously. The “actual accessory continuous actuating device” that can perform the operation is called MB (middle bonus) / CB (chance bonus).

  Therefore, the slot machine installed in the pachinko hall should be about 70% or 60% due to the existence of the regulation (4) above, but the conventional slot machine has no confirmation of the ratio. Because the function that can be done was not installed, the role ratio could not be confirmed.

As one of the so-called goto acts, there is one that exploits the ball illegally by increasing the bonus probability of the slot machine excessively from the normal state and making the bonus games occur frequently, and early detection of such goto acts Therefore, since it is effective to check the role ratio, recently, mounting of a role ratio check function in a slot machine has been studied (for example, see Patent Document 1).

When the first value (TO_6000 / TO_ALL) is a predetermined integer value, a fraction (YH_6000, RH_6000 / YH_ALL, RH_ALL) corresponding to an integer value corresponding to the second value (YO_6000, RO_6000 / YO_ALL, RO_ALL) is obtained. A control device (31) for calculating,
In the step of calculating the fraction (YH_6000, RH_6000 / YH_ALL, RH_ALL),
The dividend with an initial value of zero is shifted bit by bit in the upper direction, and each bit value from the most significant bit to the least significant bit of the product of the first value (TO_6000 / TO_ALL) and the predetermined integer value is converted to the highest value. A first step of repeating a bit shift process for shifting to the least significant bit of the dividend one bit at a time from the highest bit,
A second step of determining whether the dividend is equal to or greater than the second value (YO_6000, RO_6000 / YO_ALL, RO_ALL) for each of the bit shift processes in the first step;
When an affirmative determination is made in the second step, when the bit of the product shifted to the least significant bit of the dividend is the Nth (N is an integer greater than or equal to 1) bit immediately before the determination, the fraction And a third step of subtracting the second value (YO_6000, RO_6000 / YO_ALL, RO_ALL) from the dividend and shifting to the first step. .

  According to the gaming machine of the present invention, in a control program for a gaming machine that is required to be written in a Z80-based assembler language, when a denominator value such as a role ratio is a predetermined integer value, It is possible to improve the efficiency of a calculation algorithm for calculating a fraction of an integer value corresponding to

  When the MAX bet button 17, the single bet button 18, the start lever 19, the left stop button 20L, the middle stop button 20C, the right stop button 20R, and the checkout button 21 are operated, the switches or sensors provided individually for them are operated. A signal is output, and the signal is input to the CPU 41 via the input / output port 44. Each time the left reel 4L, middle reel 4C and right reel 4R make one rotation, signals are output from the left reel position detection sensor 51L, middle reel position detection sensor 51C and right reel position detection sensor 51R, respectively. The data is input to the CPU 41 via the input / output port 44. Each time a medal is inserted from the medal insertion slot 16, a detection signal is output from the medal insertion sensor 52, and the detection signal is input to the CPU 41 via the input / output port 44. Each time the medal payout drive motor 63 is driven and a medal is paid out from the medal storage unit, a signal is output from the medal payout sensor 53, and the signal is input to the CPU 41 via the input / output port 44.

  Stepping motors are employed as the left reel drive motor 61L, the middle reel drive motor 61C, and the right reel drive motor 61R. When the start lever 19 is operated after a specified number of medals are bet on the game, the CPU 41 inputs drive pulse signals to the left reel drive motor 61L, the middle reel drive motor 61C, and the right reel drive motor 61R, and the left The rotation of the reel 4L, the middle reel 4C, and the right reel 4R is started.

Based on the number of outputs, the rotational positions of the left reel 4L, middle reel 4C, and right reel 4R are always grasped.

  Further, when the start lever 19 is operated, the CPU 41 executes an internal lottery. Specifically, the CPU 41 acquires a random number from the random number generation circuit 47 at the timing when the start lever 19 is operated. Then, the CPU 41 refers to the lottery table stored in the ROM 42. In the lottery table, a range of random numbers (for example, 0 to 65535) generated by the random number generation circuit 47 is divided into a plurality of lottery sections, and one or more roles are associated with each lottery section. The CPU 41 determines the winning combination corresponding to the lottery classification to which the random number acquired from the random number generation circuit 47 belongs as the winning combination. In addition, when the random number acquired from the random number generation circuit 47 does not belong to any lottery category, the CPU 41 determines that the result of the internal lottery is unfair (pure loss).

  Thereafter, when the rotation speeds of the left reel 4L, middle reel 4C and right reel 4R become constant, the CPU 41 activates the left stop button 20L, middle stop button 20C and right stop button 20R. When the left stop button 20L, middle stop button 20C, and right stop button 20R are operated, the CPU 41 determines the timing at which the left stop button 20L, middle stop button 20C, and right stop button 20R are operated, and the result of the internal lottery. Based on the above, output of drive pulse signals to the left reel drive motor 61L, middle reel drive motor 61C and right reel drive motor 61R is stopped, and the stop of the left reel 4L, middle reel 4C and right reel 4R is controlled. At this time, the rotation of the left reel 4L is stopped within the pull-in range in which the symbols corresponding to the predetermined number of frames move with reference to the rotation position of the left reel 4L at the timing when the left stop button 20L is pressed (retraction control). ). The same applies to the middle reel 4C and the right reel 4R.

  Then, the CPU 41 determines whether a combination of symbols corresponding to the winning combination in the internal lottery is arranged on the active line. If there is a combination of symbols corresponding to the winning combination on the active line, the CPU 41 determines that the winning combination is a winning combination, and executes processing according to the winning combination.

<About 6.6000 games / total game payout update processing>
FIG. 8 shows a flowchart of the 6000 game / all game payout number update process executed by the CPU 41 of the main control device 31.
Since this process involves updating various data stored in the second work area WORK2_AREA of the RAM 43 of the main controller 31, the processing program is stored in the second program area PG2_AREA of the ROM 42 of the main controller 31. Yes.
For this reason, this process is executed in the interrupt-prohibited section, as can be seen from the fact that interrupts are prohibited in the first step S801 and interrupts are allowed in the last step S809. Hereinafter, each step executed in the interrupt prohibited section will be described.

In step S802, the total payout work TOW is added to the total payout TO_ALL for all games, the bonus payout work YOU is added to the total game payout YO_ALL, and the combined payout work ROW is added to the all game combined payout RO_ALL.
In the next step S803, of the 15 data sets Rg1 to Rg15 constituting the ring buffer, the update (overwrite) target data set (the update target data set number is N, N = 1 to 15) is updated. Perform (overwrite) processing.
Specifically, the total payout work TOW is set in the total payout TO (N) of the data set to be updated (overwritten), the feature payout work YOU is set in the payout YO (N), and the combined payout RO ( N) sets the combined payout work ROW.

In the next step S804, 6000 game total payout TO_6000, 6000 game combination payout YO_6000, and 6000 game combination payout RO_6000 are calculated.

<About 8.6000 Game Character Ratio Update Processing>
<8-1. First Example>
FIG. 10 shows a flowchart of the 6000 game accessory ratio YH — 6000 update process executed by the CPU 41 of the main control device 31.
First, in step S1001, a value obtained by multiplying the dividend 6000 game total payout TO_6000 by 100, a divisor 6000 game accessory payout TO_6000, and a percentage set to zero, respectively.
In the 6000 game consecutive combination ratio update process, instead of the above, a value obtained by multiplying the dividend 6000 game total payout TO_6000 by 100 and a 6000 game combination consecutive payout RO_6000 are set as the divisor.
In the all game combination ratio update processing, instead of the above, a value obtained by multiplying the total game total payout TO_ALL by 100 is set as the dividend, and all game combination continuous payout YO_ALL is set as the divisor.
In the all-game combination ratio update process, instead of the above, a value obtained by multiplying the total game total payout TO_ALL by 100 is set as the dividend, and the all-game combination payout RO_ALL is set as the divisor.

In the next step S1002, the percentage calculation process A is executed. In the next step S1003, it is determined whether or not the return value of the process is an end value. The percentage calculated in the percentage calculation process A is set in the ratio YH_6000, and the process returns.
In the 6000 game combination ratio update process, instead of the above, the percentage calculated in the percentage calculation process A is set to the 6000 game combination ratio RH_6000.
In the all game accessory ratio update process, instead of the above, the percentage calculated in the percentage calculation process A is set to the all game accessory ratio YH_ALL.
In the all game combination ratio update process, instead of the above, the percentage calculated in the percentage calculation process A is set to the all game combination ratio RH_ALL.

FIG. 11 shows a flowchart of the percentage calculation process A executed by the CPU 41 of the main control device 31.
Since this process involves updating various data stored in the second work area WORK2_AREA of the RAM 43 of the main controller 31, the processing program is stored in the second program area PG2_AREA of the ROM 42 of the main controller 31. Yes.
For this reason, this processing is executed in the interrupt-prohibited section, as can be seen from the fact that interrupts are prohibited in the first step S1101 and interrupts are allowed in the last step S1110. Hereinafter, each step executed in the interrupt prohibited section will be described.

In step S1102, zero is set to the number of loops. In the next step S1103, the work variable A is set as a result of subtracting the divisor from the dividend. In the next step S1104, it is determined whether or not the value of the work variable A is less than zero. If it is determined as YES, an end value is set as a return value in step S1109, and the process proceeds to step S1110.
On the other hand, if NO is determined in step S1104, the value of the work variable A is set to the dividend in step S1105, and the percentage and the number of loops are incremented by 1 in the next step S1106, respectively. Migrate to

  In the next step S1107, it is determined whether or not the number of loops has reached 50. If NO is determined, the process returns to step S1103. If YES is determined, the return value is continued in step S1108. Is set, and the process proceeds to step S1110.

As can be seen from the above description, in the percentage calculation process A, in step S1103, the process of subtracting the divisor from the dividend is repeated until the subtraction result becomes negative, and the number of repetitions is set to the percentage. Is adopted.
Therefore, although the maximum number of repetitions of the subtraction process is 100, it is necessary to execute the percentage calculation process A during the interrupt prohibition period. Therefore, the timer interrupt period is 1.5 milliseconds and the timer interrupt process is performed. In consideration of the longest time required for execution of the above, it has been found that there is a possibility that a malfunction may occur due to the delay of the timer interrupt process when the subtraction process is performed 100 times at the maximum in the percentage calculation process A. did.

Therefore, 50 is set as the maximum number of repetitions of the subtraction process, and when the subtraction process is executed 50 times, the percentage calculation is temporarily interrupted to cancel the interrupt prohibition period. Thereby, the said malfunction can be avoided.
Note that the maximum number of repetitions of the subtraction process in the percentage calculation process A is set to a value that does not cause a problem in consideration of the timer interrupt cycle and the longest time required to execute the timer interrupt process. Good. Specifically, it may be set to the number of repetitions of the subtraction process that can be reliably executed during the remaining time excluding the longest time required to execute the timer interrupt process from the timer interrupt period.

<8-2. Second Embodiment>
In the percentage calculation process A of the first embodiment, the simplest logic is adopted in which the maximum number of subtraction processes is 100. However, in the second embodiment, the maximum number of subtraction processes can be seven. Adopt efficient logic.
The second embodiment will be described below.

FIG. 12 shows a flowchart of the 6000 game accessory ratio YH — 6000 update process executed by the CPU 41 of the main control device 31.
First, in step S1201, a value obtained by multiplying the dividend of 6000 games total payout TO_6000 by 100, a divisor of 6000 game accessory payout TO_6000, and a percentage of zero are set.
In the 6000 game consecutive combination ratio update process, instead of the above, a value obtained by multiplying the dividend 6000 game total payout TO_6000 by 100 and a 6000 game combination consecutive payout RO_6000 are set as the divisor.
In the all game combination ratio update processing, instead of the above, a value obtained by multiplying the total game total payout TO_ALL by 100 is set as the dividend, and all game combination continuous payout YO_ALL is set as the divisor.
In the all-game combination ratio update process, instead of the above, a value obtained by multiplying the total game total payout TO_ALL by 100 is set as the dividend, and the all-game combination payout RO_ALL is set as the divisor.

In the next step S1202, the percentage calculation process B is executed, and in the next step S1203, the percentage calculated in the percentage calculation process B is set to the 6000 game accessory ratio YH_6000, and the process returns.
In the 6000 game combination ratio update process, instead of the above, the percentage calculated in the percentage calculation process A is set to the 6000 game combination ratio RH_6000.
In the all game accessory ratio update process, instead of the above, the percentage calculated in the percentage calculation process A is set to the all game accessory ratio YH_ALL.
In the all game combination ratio update process, instead of the above, the percentage calculated in the percentage calculation process A is set to the all game combination ratio RH_ALL.

FIG. 13 shows a flowchart of the percentage calculation process B executed by the CPU 41 of the main control device 31.
Since this process involves updating various data stored in the second work area WORK2_AREA of the RAM 43 of the main controller 31, the processing program is stored in the second program area PG2_AREA of the ROM 42 of the main controller 31. Yes.
For this reason, this processing is executed in the interrupt-prohibited section, as can be seen from the fact that interrupts are prohibited in the first step S1301 and interrupts are allowed in the last step S1316. Hereinafter, each step executed in the interrupt prohibited section will be described.

First, in step S1302, zero is set to the loop counter N, and in step S1303, the minimum number of bits necessary to represent the dividend is set to Nmax.
FIG. 14 shows a specific example when the dividend is 424,000 and the divisor is 80000.
In this case, the percentage is 53, but the specific example will also be described with reference to FIG. 14 as appropriate in the description of each step of FIG. 13 below.
In the specific example shown in FIG. 14, the minimum number of bits necessary to represent the dividend 424000 is 23 bits, so Nmax is 23.

Returning to FIG. 13, in the next step S1304, N is incremented by 1, and in step S1305, a value corresponding to N bits is set from the most significant bit of the dividend.
In the next step S1306, it is determined whether or not the remainder is greater than or equal to the divisor. If NO is determined, it is determined in step S1315 whether or not N has reached Nmax. If NO is determined in step S1315, the process returns to step S1304. If YES is determined, the process proceeds to step S1316.

  If it is determined as YES in step S1306, 1 is set to the (Nmax-N + 1) bit of the percentage in step S1307, and the divisor is subtracted from the remainder in step S1308. Transition.

  In the specific example shown in FIG. 14, it is determined in step S1306 that the answer is YES when N becomes 18. The remainder at this time is a value corresponding to the upper 18 bits of the dividend, ie, 132500. Become. Thereafter, in step S1307, 1 is set to the (Nmax (= 23) −N (= 18) +1) bit of the percentage, that is, the sixth bit, and in step S1308, the divisor is calculated from the remainder (= 132500). (= 80000) is subtracted and the remainder becomes 52500.

  Returning to FIG. 13, in the next step S1309, N is incremented by 1, and in step S1310, it is determined whether N is larger than Nmax. If it is determined as YES in step S1310, the process proceeds to step S1316. If it is determined NO, the process proceeds to step S1311.

In step S1311, the remainder is shifted to the upper side by one bit (left shift), and the value of the Nth bit from the most significant bit of the dividend is set as the least significant bit of the remainder.
In the next step S1312, it is determined whether or not the remainder is greater than or equal to the divisor. If NO is determined, the process returns to step S1309. If YES is determined, the percentage (Nmax−N + 1) is determined in step S1313. ) 1 is set to the bit, and the divisor is subtracted from the remainder in step S1314, and the process returns to step S1309.

  In the specific example shown in FIG. 14, when N is 19, the remainder is 105000 as a result of the process in step S1311. Since the remainder is larger than the divisor (= 80000), it is determined as YES in step S1312, and then, in step S1313, the percentage (Nmax (= 23) −N (= 19) +1) th bit, that is, 5th. In addition to setting 1 to the bit, in step S1314, the divisor (= 80000) is subtracted from the remainder (= 105000), and the remainder becomes 25000.

  After step S1314, if N is 20 in step S1309, the remainder is 50,000 as a result of the process in step S1311. Since the remainder is smaller than the divisor (= 80000), NO is determined in step S1312, the process returns to step S1309, and N becomes 21.

  When N is 21, the remainder is 100000 as a result of the process in step S1311. Since the remainder is larger than the divisor (= 80000), it is determined as YES in step S1312, and then, in step S1313, the percentage (Nmax (= 23) −N (= 21) +1) th bit, that is, 3 In addition to setting 1 to the bit, in step S1314, the divisor (= 80000) is subtracted from the remainder (= 100000), and the remainder becomes 20000.

  After step S1314, when N becomes 22 in step S1309, the remainder is 40000 as a result of the process in step S1311. Since the remainder is smaller than the divisor (= 80000), NO is determined in step S1312, the process returns to step S1309, and N becomes 23.

When N is 23, the remainder is 80000 as a result of the process in step S1311. Since the remainder is equal to the divisor (= 80000), it is determined as YES in step S1312, and then, in step S1313, the percentage (Nmax (= 23) −N (= 23) +1) th bit, that is, 1 bit In addition to setting 1 to the eye, in step S1314, the divisor (= 80000) is subtracted from the remainder (= 80000), and the remainder becomes 0.
Thereafter, the process returns to step S1309, N becomes 24, it is determined as YES in step S1310, and the process proceeds to step S1316.
As a result, the percentage is 110101 in binary, ie 53.

As can be seen from the above description, in the percentage calculation process B of the second embodiment, the maximum number of subtraction processes is the number of bits necessary to represent 100, which is the maximum percentage value, that is, seven times.
Further, since processing other than subtraction processing is bit shift processing and logical operation, processing time is not required. Therefore, as in the percentage calculation process A of the first embodiment, the percentage calculation is performed in one continuous short interruption prohibition period without temporarily interrupting the calculation of the percentage and canceling the interruption prohibition period. Since it can be completed, the timer interrupt process is not delayed. Therefore, there is no problem caused by this.

  As described above, according to the percentage calculation process A of the first embodiment or the percentage calculation process B of the second embodiment, the combination ratio and the combination ratio without causing a problem due to the delay of the timer interruption process. Can be calculated.

  Note that the 6000 game combination ratio YH_6000, the 6000 game combination ratio RH_6000, the all game combination ratio YH_ALL, and the all game combination ratio RH_ALL are displayed on the combination display device YH when the front door 3 is opened. . The display update process of the role display device YH is executed by a timer interrupt process. Specifically, after the front door 3 is opened, a 6000 game accessory ratio YH_6000 is displayed on the role ratio display device YH for a certain time (for example, 5 seconds), and after a certain time has passed, the 6000 game combination is further performed for a certain time. The four types of ratios are sequentially displayed on the role ratio display device YH, such as the ratio RH_6000 being displayed on the role ratio display device YH.

Although one embodiment of the present invention has been described above, the present invention can be modified in various ways within the scope of matters described in the claims.
For example, although the embodiment in which the present invention is applied to the slot machine has been described above, it is needless to say that the present invention can be applied to a pachinko gaming machine using a Z80-based CPU as the CPU of the main control device, similarly to the slot machine. is there.

  In the above, the embodiment in which the present invention is applied to the calculation of the percentage has been described. However, the present invention is not limited to the percentage, and in the slot machine or the pachinko gaming machine, the first value and the first value that does not become larger than the first value. With respect to binary values, when the first value is a predetermined integer value, the second value can be calculated as a fraction corresponding to an integer value. It is.
