Description

  The present invention relates to a gaming machine such as a slot machine, a winning determination method for a gaming machine, and a program.

  A gaming machine such as a slot machine is provided with a medal slot so that a player can enjoy a game by inserting a predetermined number of medals. The medals necessary for the game can be borrowed with a medal lending machine provided in the game hall, and the game can be started by inserting it into the medal slot of a desired gaming machine.

The operation of the conventional gaming machine was as follows.
First, when the start switch is operated, the start switch is turned on. In response to this, a lottery process is performed by the winning determination means inside the gaming machine. Here, when a predetermined combination is won, a winning flag is set. The rotating reel starts to rotate. When the stop switch is operated, the stop switch is turned on. Then, the rotation of the corresponding rotating reel is stopped. After the stop switches corresponding to all the rotating reels are operated, whether or not the winning symbols corresponding to the winning flag are aligned on the effective winning line while the winning flag is established, that is, whether or not the winning is confirmed Is determined. When it is determined that the winning is confirmed, a medal corresponding to the winning symbol is paid out.

  For example, when the evaluation of the lottery process is out of place, it is set so that the predetermined symbols are not aligned (so-called kicking), and when winning, the predetermined symbols are aligned on the condition that the stop switch is pressed at a predetermined timing. (So-called pull-in). In other words, only when winning in the lottery process, medals are paid out by winning a winning pattern under a predetermined condition, but when not winning, medals are paid out regardless of how the stop switch is operated. There is no. This is to keep the medal payout at a certain probability. In order to realize this, a random number generator is used in the lottery process.

Individual designs are projected.

  FIG. 5 is a block diagram showing an electrical schematic structure of the slot machine 100. In this figure, the display about the power supply system is omitted. The slot machine 100 includes a main substrate 1 and a sub substrate 2 that operates in response to a command from the main substrate 1 as main processing devices. At least the main substrate 1 is accommodated inside the case so that it cannot be contacted from the outside, and a sealing process is performed so that traces remain when the substrates are removed.

  The main board 1 is for performing an internal lottery in response to a player's operation, and processing such as reel rotation / stop and medal payout. The main board 1 includes a CPU that performs a control operation according to a preset program, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like. The main board 1 includes a winning determination means 1a for performing a winning lottery (details will be described later). This process is executed by the CPU of the main board 1, for example. A program for performing this processing is written in the ROM of the main board 1 in advance.

  The sub-board 2 is for receiving a command signal from the main board 1 and notifying the result of the internal lottery and performing various effects. The sub-board 2 includes a CPU that performs a control operation according to a preset program corresponding to the command signal, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like.

  The sub-board 2 receives a command from the main board 1 and performs processing such as rendering according to the command. The flow of commands is only one from the main board 1 to the sub board 2, and conversely, no command or the like is issued from the sub board 2 to the main board 1.

  The main board 1 includes a start switch 134, a stop switch 140, a reel drive unit 70, a reel position detection circuit 71, a hopper drive unit 80, a hopper 81, and a medal detection unit for counting the number of medals paid out from the hopper 81. 82 is connected. A peripheral substrate (local substrate) such as a liquid crystal control substrate 200 for controlling a liquid crystal display device (not shown), a speaker 201, and an LED substrate 202 is connected to the sub substrate 2. Hereinafter, these peripheral boards / devices excluding the start switch 134 and the stop switch 140 will be described.

  The reel driving unit 70 is a circuit that drives a stepping motor 155 that rotationally drives the three reels 40. Each stepping motor 155 is 1-2 phase excited by the reel drive circuit 70 and rotates once when a drive signal of a predetermined number of pulses is supplied.

  The reel position detection circuit 71 is provided in the vicinity of the reel 40, receives an output pulse signal from the photo interrupter 159 for detecting the rotation position of the reel 40, detects the rotation position of each of the three reels 40, and detects the detection signal. Is output. An output pulse of the photo interrupter 159 is given to the CPU of the main board 1 through the reel position detection circuit 71. In the RAM of the main board 1, a count value (specifically, a value obtained by counting pulses for driving the stepping motor) corresponding to the rotation position within one rotation range for each reel 40 is a driving pulse for the stepping motor. When the CPU receives a reset pulse, the count value formed in the RAM is cleared to “0”. By this clearing process, the deviation generated between the movement display of each symbol and the rotation of each stepping motor is eliminated every rotation.

  The hopper driving unit 80 is a circuit that drives a motor of a hopper 81 that stores medals and pays out the number of medals corresponding to the designated winning.

  The medal detection unit 82 is for counting the number of medals paid out from the hopper 81. The CPU of the main board 1 stops driving by the hopper driving unit 80 when the actually paid out medal count value received from the medal detection unit 82 reaches the predetermined payout number data corresponding to the winning. Finish paying out. A predetermined number of medals are paid out to the player by the hopper driving circuit 80 and the medal detection unit 82 based on a winning obtained as a result of the game.

The liquid crystal control board 200 is a circuit for driving the liquid crystal display unit 62.
The speaker 201 is for generating sound such as voice and sound effects.
The LED substrate 202 is a circuit for driving a display lamp and a back lamp (not shown).

  The liquid crystal display device 62 controlled by the liquid crystal control substrate 200 and the LED substrate 202 including the speaker 201 and the display lamp constitute an effect display device. This effect display device is for notifying a player of winning or the like, or for teaching a user a specific small role during a certain game with some action during a so-called assist time (AT).

The ROM of the main board 1 stores game processing procedures executed in the slot machine 100 as a sequence program, and stores a winning probability table, a symbol table, a winning symbol combination table, and the like. Has been. The winning probability table is divided to divide the extracted random numbers (details will be described later) into each winning mode, and stores data that divides the random numbers extracted from a certain range of numerical values into each winning mode. ing. That is, the winning probability table has an area divided for each winning mode corresponding to the entire area of random numbers. For example, a range of 0 to a certain number is divided into a plurality, one division (region) is excluded, and the other division (region) is set as winning 1, winning 2,. The extracted random number data is collated with each of the winning determination area data divided for each winning mode in all areas corresponding to the random number, and the winning corresponding to the winning mode to which the extracted random number data belongs is determined. The For example, it is checked which category (region) in the winning probability table the extracted random number value is, and if the category is, for example, a category of winning 1, it is determined as “winning 1”. Similarly, if the extracted random number value belongs to the category (area) out of the winning determination table 5, it is determined as “out”. For example, when the evaluation of the lottery process is out of place, the predetermined symbols are set so as not to be aligned (so-called kicking), and when winning, the predetermined symbols are aligned on the condition that the stop switch is pressed at a predetermined timing. (So-called pull-in). And if predetermined symbols are prepared, medals corresponding to winning symbols are paid out. Various winnings occur under the probability according to the data setting of the winning probability table and the symbol stop control is performed. Therefore, for example, the business hours of the day are not influenced by the skill of the player. The total medal payment rate is maintained almost constant.
Normally, the position of the reel when the stop switch is pressed (pressed position) and the position of the reel when stopped (stop position) do not match. This is because the reel cannot be stopped at the moment when the stop switch is pushed down due to the inertia of the reel, and the stop position of the reel is adjusted by the pull-in / kick-up according to the winning result by the stop control described above. Because it is done.

  FIG. 6 is a block diagram of the winning determination means. At least some of the functions of the winning determination means are realized by the CPU executing the program stored in the ROM of the main board 1 or by hardware. As shown in FIG. 6, the winning determination means includes a random number generator 2, a random number extractor 3, a determination unit 4, a winning determination table 5, a reel position determination unit 6, a numerical value acquisition unit 7, and a synthesis unit 8. The configuration of the winning determination means is not limited to that shown in FIG.

  The random number generator 2 generates a random number for winning lottery within a predetermined area. For example, an arbitrary numerical value is generated with a predetermined probability in a range of 0 to a certain number. Specifically, the random number generator 2 is a counter that repeats +1 at regular time intervals and returns to 0 when a certain value (for example, FFFF (hexadecimal)) is exceeded.

  The random number extractor 3 extracts a random number generated by the random number generator 2 under a predetermined condition (for example, operation of the start switch 134). The random number generator 2 repeatedly generates random numbers at predetermined intervals, and a part of them is extracted by the random number extractor 3. Specifically, the random number extractor 3 is a latch.

  The reel position determination unit 6 determines the position of the rotating reel when the stop switch 140 is pressed based on a signal from the reel position detection circuit 71 for all or a part of the plurality of rotating reels 40a to 40c (hereinafter referred to as “pressed position”). And / or the position of the rotating reel at the time of stopping (hereinafter referred to as “stop position”) is determined. 21 symbols are displayed on each of the rotating reels 40a to 40c, and the reel position determination unit 6 has, for example, 1 to 21 as numerical values indicating the positions of the symbols with respect to the rotational positions of the rotating reels 40a to 40c. Assign a numeric value.

  The numerical value acquisition unit 7 converts the pressed position and / or the stop position into numerical values. Although the numerical values of 1 to 21 indicating the pressed position and / or the stopped position can be used as they are, it is preferable to convert the numerical values to other numerical values in order to make prediction difficult.

  The combining unit 8 combines the random number extracted by the random number extractor 3 and the numerical value acquired by the numerical value acquiring unit 7. Combining is, for example, combining at least two numerical values into one numerical value by performing arithmetic operations including addition, subtraction and multiplication / division, or logical operations including logical sum, logical product and exclusive logical sum. is there.

  Specifically, the numerical value acquisition unit 7 and the synthesis unit 8 perform the following processing. In the following description, it is assumed that the pressed position and / or the stop position are numerical values.

(1) A random number of times corresponding to the pressed position and / or stop position of the three rotating reels 40a to 40c is repeatedly extracted (for example, the numerical value acquisition unit 7 calculates a value corresponding to the pressed position and / or stop position as a random number). The random number extractor 3 repeatedly extracts random numbers generated by the random number generator 2 as many times as the number of random number extractions triggered by the start switch signal), and synthesizes a number of the obtained random numbers. (The details of these processes will be described later). In addition to using all the three rotating reels 40a to 40c, only one or any two pressing positions and / or stop positions may be used.

(2) A composite value table in which numerical values are stored in advance corresponding to the pressed position and / or stop position is provided, and all or a part of the three rotary reels 40a to 40c are pressed and / or stopped. The numerical value is read from the combined value table, and the read numerical value is combined with the random number extracted by the random number extractor 3 (details will be described later).

(3) Arithmetic operations including addition, subtraction, and multiplication / division based on all or part of the pressed positions and / or stop positions of the three rotating reels 40a to 40c, conversion by linear or nonlinear functions, or logical sum, By performing a logical operation including a logical product and an exclusive OR, it is converted into another numerical value, and the converted numerical value is combined with the random number extracted by the random number extractor 3.

  The winning determination table 5 has an area divided for each winning mode corresponding to the entire area of random numbers taken by the random number generator 2. For example, a range of 0 to a certain number is divided into a plurality, one division (region) is excluded, and the other division (region) is set as winning 1, winning 2,.

  The determination unit 4 refers to the numerical value (random number for extraction) obtained by the synthesis unit with the lottery probability data in the winning determination table 5. That is, the extracted random number data is collated with each of the winning determination area data divided for each winning mode in the entire random number region taken by the random number generator 2, and the winning corresponding to the winning mode to which the extracted random number data belongs is determined. To decide. For example, it is determined to which category (region) of the winning determination table 5 the extracted random number value belongs, and if the category is, for example, a category of winning 1, it is determined as “winning 1”. Similarly, if the extracted random number value belongs to the category (area) out of the winning determination table 5, it is determined as “out”.

  For example, when the evaluation of the lottery process is out of place, it is set so that the predetermined symbols are not aligned (so-called kicking), and when winning, the predetermined symbols are aligned on the condition that the stop switch is pressed at a predetermined timing. (So-called pull-in). And if predetermined symbols are prepared, medals corresponding to winning symbols are paid out.

  According to the embodiment of the invention, the random number for lottery is combined with the numerical value acquired based on the position of the rotating reel, thereby increasing irregularity of the random number and making it difficult to predict. Even if the player skillfully operates the start switch, a desired random number cannot be obtained. The same applies when an unauthorized device such as a so-called “hanging substrate” is used. Therefore, according to the embodiment of the invention, fraudulent acts can be suppressed.

  Next, a description will be given of the process (1) described above. FIG. 8 is a block diagram of the winning determination means 1a for executing the process, FIG. 9 is a process flowchart (corresponding to S3 in FIG. 7: acquisition of random numbers), and FIG. 10 is a timing chart for explaining the process. It is.

  The apparatus shown in FIG. 8 generates lottery random numbers by using both or one of the pressed position and stop position of each rotary reel 40 at the time of the previous game when lotteries are selected. By acquiring random numbers an indefinite number of times, and adding (synthesizing) the acquired random numbers together, it becomes difficult to aim for random numbers for lottery, and cheating by a sensory device can be suppressed.

  The numerical value acquisition unit 7 in FIG. 8 includes an extraction timing generation unit 7b. The extraction timing generation unit 7b extracts the random numbers generated by the random number generator 2 repeatedly corresponding to the pressed position and / or the stop position, and controls the random number extractor 3 so as to send them to the synthesis unit 8. A plurality of random numbers extracted by the combining unit 8 are combined. The numerical value acquisition unit 7 of FIG. 8 supplies the numerical value necessary for the synthesis to the synthesis unit 8 by giving an extraction timing signal to the random number extractor 3 instead of directly acquiring the numeric value by itself. The reel position determination unit 6 calculates and stores the pressed position and / or stop position in the previous game, and extracts the pressed position and / or stop position stored when the start switch 134 is pressed down. Send to.

  Further explanation will be given with reference to the flowchart of FIG. 9 and the timing chart of FIG.

S 30: A random number is extracted by the random number extractor 3 by depressing the start switch 134 and sent to the synthesis unit 8. This random number is stored in a buffer. Let this random number be r0.

S31: The extraction timing generation unit 7b obtains a combined value of the pressed position and / or stop position of each rotating reel. Briefly, the total value of the pressed position and stop position of the three rotating reels is obtained. This is n. The pressed position and / or stop position of each rotary reel 40 at the previous game is stored in the reel position determination unit 6.

S32: The random number extractor 3 is made to repeatedly extract random numbers by generating repeated extraction timing according to the composite value n. As shown in FIG. 10, n random numbers (r1, r2,..., Rn) are extracted. The timing at which n random numbers are extracted is arbitrary, but it is only necessary to extract random numbers at regular time intervals. By making this time interval different from the repetition cycle of random numbers, prediction becomes more difficult. For example, the extraction time interval and the random number repetition cycle are set to a prime number ratio such as 3: 5 or 7:11.

S33: The acquired random number is synthesized. In brief, the random number r is generated by adding the acquired random numbers. r = r0 + r1 + r2 +... + rn. The carry that overflowed upon addition is ignored (if the random number is 16 bits, the carry of the most significant bit is ignored and the lower 16 bits are set as the random number r). The random number r thus obtained is used for the lottery. Or you may make it add the random number used for the last lottery. (Current lottery random number) = r + (previous lottery random number).

  Note that it is not necessary to use the pressed position and / or stop position of all the rotating reels. For example, as shown in FIG. 11, any one of a plurality of rotating reels may be selected at random, and the processing of S31 to S33 may be applied to the selected rotating reel (the same applies to (2) below). . In the selection, the random number r0 can be used. For example, when the lower 2 bits of the random number r0 are 01, the first rotating reel 40a is selected, when the same is 10, the second rotating reel 40b is selected, and when the same is 11, the third rotating reel 40c is selected. When it is 00, all of the rotating reels 40a to 40c may be selected.

  Next, the process (2) described above will be described. FIG. 12 is a block diagram of the winning determination means 1a for executing the processing, and FIG. 13 is a processing flowchart (corresponding to S3 in FIG. 7: acquisition of random numbers).

  The numerical value acquisition unit 7 includes a composite value table 7c that stores numerical values in advance corresponding to the pressed position and / or the stop position. The composite value table 7c is shown in FIG. 14, for example, and numerical values x1 to x61 are associated in advance corresponding to the total values 3 to 63 of the pressed positions or stop positions of the three rotary reels 40a to 40c. The numerical values x1 to x61 are preferably random numbers.

  A description will be added with reference to the flowchart of FIG.

S 30: A random number is extracted by the random number extractor 3 by depressing the start switch 134 and sent to the synthesis unit 8. This random number is stored in a buffer. Let this random number be r0.

S31: The extraction timing generation unit 7b obtains a combined value of the pressed position and / or stop position of each rotating reel. Briefly, the total value of the pressed position and stop position of the three rotating reels is obtained. This is n. The pressed position and / or stop position of each rotary reel 40 at the previous game is stored in the reel position determination unit 6.

S32b: The numerical value xn corresponding to the total value n is read from the composite value table 7c.

S33: The acquired random number is synthesized. In short, the numerical value xn is added to the acquired random number. r = r0 + xn. A random number r is used for the lottery. Or you may make it add the random number used for the last lottery. (Current lottery random number) = r + (previous lottery random number).

  Note that when the numerical value acquisition unit 7 acquires numerical values, one of the pressed position and the stop position is used, but both of them may be used. For example, the total value of the pressed position and the stop position is calculated. In addition to the summation (addition), arithmetic operations including addition, subtraction, and multiplication / division, or logical operations including logical sum, logical product, and exclusive logical sum may be performed.
