Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a game machine. In particular, the present invention relates to a technique for determining an abnormal operation of a gaming machine.

[0002]

2. Description of the Related Art A pachinko machine, which is a type of gaming machine, will be described as an example. In a pachinko machine, three symbols displayed on the symbol display device start fluctuating when a pachinko ball wins the first type start opening, and then the symbols stopped are a predetermined combination (for example, "7,7,7"). Or “2.2.2”), the special winning opening is opened and the pachinko ball easily wins, which is a so-called big hit state. When it becomes a jackpot, many prize balls (pachinko balls) are paid out. In this way, the player recognizes whether it is a big hit or a miss by the combination of the stop symbols displayed on the symbol display device. Further, the number of pachinko balls that have won the first-class starting opening (the number of winnings) is added as the number of reserved balls, and is decremented by 1 each time the symbol variation ends. The symbol variation is repeated until the number of reserved balls becomes zero. When it is a big hit, the player recognizes whether the game state after that is a probability change state with a high probability of being a big hit state or a non-probability state with a low probability of being a big hit state depending on the combination of stop symbols Let For example, in the case of "7/7/7", when the symbol is stopped and a big hit occurs, the gaming state shifts to the probability changing state. When the symbol stops and becomes a big hit in "2.2.2", the game state shifts to the non-probable variation state. Whether or not it is a big hit, whether it is a stop symbol or a game state is a probability change state or a non-probability change state is determined by a random number acquired when a pachinko ball is won in the first-class start opening. The acquired random number, the number of reserved balls, and the like are stored in the memory provided in the control unit of the gaming machine.

[0003]

However, in a pachinko machine, static electricity is generated when a pachinko ball hit on the game board surface falls, or when the pachinko ball is supplied to the pachinko machine from the island equipment in the hall. . Therefore, the value stored in the memory may be rewritten by the electrical noise due to the static electricity. If the value stored in the memory is rewritten, the game will proceed in an abnormal state different from that determined by the obtained random number. For example, the special winning opening may be opened even if a random number that is a big hit has not been acquired, or the switching between the probable variation state and the non-probability variation state may not be correctly executed.

The present invention has been made to solve such a problem, and an object thereof is to provide a technique for determining whether or not the operation of the gaming machine is abnormal.

[0005]

[Means, Actions and Effects for Solving the Problem] The gaming machine according to claim 1 starts to fluctuate the symbol displayed on the symbol display device when a winning is made to a specific winning opening, and then stops. The player is made to recognize whether or not it is hit by the stop mode of the symbol. Then, a winning detection device that detects that a prize has been awarded to the specific winning opening, an acquisition unit that acquires information regarding the stop mode of the symbol on the condition that the winning detection device has detected a prize, and this acquisition unit, Acquired information storage means for storing a predetermined number of acquired acquisition information, acquisition number storage means for cumulatively storing the number of times information is acquired by the acquisition means, and if the symbol is not variably displayed on the symbol display device,
Using one acquisition information selected from the acquisition information stored in the acquisition information storage means, the symbols are variably displayed on the symbol display device, and the acquisition information related to the variable display is cleared from the acquisition information storage means. The symbol display means for subtracting 1 from the acquisition count stored in the acquisition count storage means, and the difference between the number of pieces of acquisition information stored in the acquisition information storage means and the acquisition count stored in the acquisition count storage means is a predetermined value. A means for determining an abnormality is provided when the value exceeds. When the information is stored in the acquisition information storage means and the acquisition count storage means in this way,
These values should increase or decrease correspondingly. Therefore, in the above gaming machine, when the difference between the number of pieces of acquisition information stored in the acquisition information storage means and the number of acquisitions stored in the acquisition count storage means exceeds a predetermined value, these memories are rewritten. It is judged that it has been done and it is judged to be abnormal.

In the gaming machine according to the first aspect, the number of pieces of acquired information stored in the acquired information storage means does not match the number of times of acquisition stored in the acquisition frequency storage means, and the difference is a predetermined value. It is preferable that a unit is provided for notifying the abnormality and notifying the number of acquisitions stored in the number-of-acquisition storage unit when the number of acquisitions is not exceeded (claim 2). This gaming machine reports an abnormality when the above conditions are satisfied and also reports the number of acquisitions stored in the acquisition number storage means. The notified number of times of acquisition can be used when the abnormality is notified and the game is stopped and then resumed. For example, the predetermined value is set to a value that does not burden the game hall. Then, when the game is restarted, the hall clerk inserts the notified number of pachinko balls into the specific winning opening. In this way, the player's dissatisfaction with the stop of the progress of the game can be reduced.

In the gaming machine according to claim 1 or 2, the acquired information storage means is provided with a plurality of areas for storing acquired information related to the acquisition of the information of 1, and the acquired information is arranged in a predetermined order in the plurality of areas. Are sequentially stored, and the symbol display means selects the acquired information of the area in the earliest stored order, and when the selected acquired information is cleared, the acquired information stored in each area is stored in the order. It is preferable to provide means for determining an abnormality when shifting to an area on the earlier side and determining that the areas where the acquired information is stored in the acquired information storage means are not continuous in a predetermined order (claim 3).
Since the storage is performed in the area of the acquired information storage means as described above, if the area where the acquired information is stored is not continuous in a predetermined order, it is determined that the memory has been rewritten, and it is determined to be abnormal. To do.

In the gaming machine according to claim 1, 2 or 3, when the acquisition means cumulatively stores the number of times the winning symbol stop mode is obtained and the winning symbol stop mode is displayed on the symbol display device. Privilege number storage means for subtracting 1 from the stored acquisition number of times,
And a unit for determining an abnormality when the difference between the number of times of acquisition stored in the privilege number storage unit and the number of acquired information corresponding to the winning symbol stop mode stored in the acquired information storage unit exceeds a predetermined value. It is preferable (claim 4). When the difference between the number of times of acquisition stored in the privilege number storage means and the number of acquired information corresponding to the winning symbol stop mode stored in the acquired information storage means exceeds a predetermined value, these memories are stored. It can be judged that it has been rewritten. Therefore, it is determined to be abnormal.

In the gaming machine according to any one of claims 1 to 4, there are specific hits and non-specific hits,
The acquisition information includes information for determining whether it is a specific hit or a non-specific hit, and a specific count storage means for storing the number of times of the specific hit and a non-specific number storage means for storing the number of non-specific hits are provided. When the number of times stored in the means and the number of times stored in the non-specific number storage means do not match the number of hits obtained from the acquisition information stored in the acquisition information storage means within a predetermined value, it is determined to be abnormal It is preferable to do so (claim 5). When the number of times stored in the specific number storage means and the number of times stored in the non-specific number storage means do not match the number of hits obtained from the acquisition information stored in the acquisition information storage means within a predetermined value, It can be judged that these memories have been rewritten. Therefore, it is determined to be abnormal.

In the gaming machine according to any one of claims 1 to 5, the abnormality determination is such that when a winning is made to a specific winning opening, when a symbol starts to fluctuate, while the symbol is fluctuating, the symbol stops fluctuating. When it does, it is preferable to be performed by at least one of (Claim 6). With this configuration, the abnormality determination can be performed at each of the above timings.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment in which the present invention is applied to a pachinko machine 10, which is a type of gaming machine, will be described with reference to FIGS. First, the configuration of the pachinko machine 10 will be briefly described. As shown in FIG. 1, at the bottom of the pachinko machine 10, there is provided a handle 38 which is operated by a player to hit a pachinko ball. On the flat game board surface 12, rails 4 extending upward in an arc shape
4, a display device 14, a first-type starting opening 30, a big winning opening 34, a gate 17, a normal winning opening 18 and the like are arranged. A large number of nails (not shown) are struck on the game board surface 12. The display 14 is, as shown in FIG. 2, a symbol display device 22, which is a liquid crystal display for displaying symbols,
The decoration 14a is provided around it, and includes a holding ball lamp 28 including four LEDs.

A warp inlet 15 is provided at the upper portion of the display 14 and a warp outlet 16 is provided at the lower portion. Warp entrance 15
The warp outlet 16 communicates with the back side of the indicator 14.
Therefore, the pachinko ball that has entered from the warp entrance 15 passes through the back side of the indicator 14 and comes out from the warp exit 16.
The pachinko ball that has exited from the warp exit 16 moves to the central portion 21a of the shelf board along the shelf board 21 that is formed so as to project to the front side under the indicator 14, and falls from that portion. As shown in FIG. 1, the shelf central portion 21a is
It is arranged directly above the first type starting port 30. Therefore, the pachinko ball falling from the central portion 21 a of the shelf board has a high probability of winning the first-class starting opening 30.

The first-type starting port 30 includes two movable blades 30.
a. The movable wing piece 30a is normally arranged vertically, but when a predetermined condition (described later) is established, the movable wing piece 30a is opened outward so that a pachinko ball can easily enter the first-type starting opening 30. Inside the first type starting opening 30, a starting opening sensor 56 for detecting a winning of a pachinko ball is provided.
Further, a sensor (not shown) for detecting the winning of a pachinko ball is also provided inside the normal winning opening 18. The special winning opening 34 arranged below the first type starting opening 30 includes a rectangular plate-shaped opening / closing door 36 that opens to the front side with the lower side as an axis. The opening / closing door 36 is connected to a solenoid 50 mounted on the back side of the game board surface 12, and is opened and closed by being driven by the solenoid 50. Further, inside the special winning opening 34, a V zone (not shown) which is a special winning area is provided.

A gate sensor 54 is mounted inside the gate 17 arranged on the left side of the game board surface 12. The gate sensor 54 has a function of detecting a pachinko ball passing through the gate 17. Three windmills 25 provided on the game board surface 12 can rotate around their axes. A speaker 26 is mounted on the back side of the pachinko machine 10. In addition, a plurality of lamps 27 that emit light by light bulbs or LEDs are arranged at various places around the game board surface 12. At the lower part of the pachinko machine 10, a lower plate 40 for temporarily storing prize balls and lending balls, a ball removing lever 33, an upper plate 46 for receiving prize balls, an ashtray 42, etc. are mounted. When the ball removing lever 33 is slid laterally, the bottom surface of the lower plate 40 is opened and the pachinko ball can be removed from the lower plate 40. The lower plate 40 is equipped with a full tank switch (not shown) for detecting that the pachinko ball is full.

On the back side of the gaming machine 10, the main control unit 10
0, the display control unit 200, and the prize ball control unit 300 are mounted (the main control unit 100, the display control unit 200, and the prize ball control unit 300 are not shown in FIG. 1). ing). Starting port sensor 5 of the first type starting port 30
6. When the gate sensor 54 or the like of the gate 17 detects winning or passing of a pachinko ball, the detection signal is the main control unit 1.
00 for processing. Then, the control signal is transmitted from the main controller 100 to the display controller 200 and the prize ball controller 30.
It is output to 0. The display control unit 200 and the prize ball control unit 300 which have received the control signal output from the main control unit 100.
Further processes the control signal and outputs it. The control signal output from the display control unit 200 is the symbol display device 22.
A pattern is displayed, a sound is generated from the speaker 26, and the lamp 27 is caused to emit light. Prize ball control unit 30
The control signal output from 0 controls the prize ball payout device 60 (not shown in FIG. 1, shown in FIG. 3). The configurations of the main control unit 100, the display control unit 200, and the prize ball control unit 300, and the processing operations executed therein will be described in detail later.

The general operation of the pachinko machine 10 will be briefly described. When the player operates the handle 38 and hits a pachinko ball, the pachinko ball reaches the upper part of the game board surface 12 along the rails 44, collides with a large number of nails hit on the game board surface 12, and frequently moves in that direction. Fall while changing. The windmill 25 rotates when a pachinko ball hits, and suddenly changes the falling direction of the pachinko ball. When a pachinko ball wins the first type starting opening 30 and the starting opening sensor 56 detects this, three prize balls are paid out and the three symbols displayed side by side on the symbol display device 22 fluctuate. Start, then stop. Then, when the combination of these stopped symbols is a predetermined jackpot pattern, the pachinko machine 10 shifts to the jackpot state. The combination of jackpot symbols is, for example, "7
・ 7/7 ”,“ 3/3/3 ”, and“ 1.1.1 ”.

Further, in the case of a big hit, depending on the combination of the big hit symbols, the game state thereafter shifts to a probability change state with a high probability of being a big hit, or a non-probability change state with a low probability of being a big hit. (For example, when the jackpot pattern “7,7,7” is stopped and displayed, it shifts to the probability change state, and when the jackpot symbol “1.1.1” is stopped and displayed, it shifts to the non-determined change state) .

When the pachinko machine 10 shifts to the big hit game state, the opening / closing door 3 of the special winning opening 34 which is normally closed
6 is driven by the solenoid 50 and opened. The opened / closed door 36 is closed when either one of 10 pachinko balls is won after being opened or 30 seconds elapses after being opened. When the pachinko ball passes through the V zone in the special winning opening 34 while the opening / closing door 36 is open, the opening / closing door 36 is closed and then opened again. The repeated opening and closing of the open / close door 36 is repeated up to 16 times, and 15 pachinko balls are paid out for each pachinko ball that wins the open / close door 36. Therefore, when the pachinko machine 10 shifts to the jackpot gaming state, 2000 or more prize balls are paid out.
When the gate sensor 54 detects that the pachinko ball has passed through the gate 17, a plurality of normal symbols fluctuates in the normal symbol display portion 19 displayed at the lower left of the symbol display device 22.
Then, when this normal pattern is a predetermined combination, the movable wing piece 30a of the first type starting opening 30 is opened for 1 second, and it is easy to win a pachinko ball.

When a pachinko ball is won in the first type starting opening 30, the number of winning balls is stored as the number of reserved balls, and the reserved ball lamps 28 corresponding to the number of reserved balls are turned on. When the symbol variation is started, the number of reserved balls is decremented by one. Symbol display device 22
When a pachinko ball wins the first-class starting opening 30 while the symbol is changing, the number of the reserved ball lamps 28 is increased. Then, the symbol variations corresponding to the number of the lit holding ball lamps are continuously performed. The upper limit of the number of reserved balls is four. Therefore, even if five or more pachinko balls win the first type starting opening 30 during the pattern change, the fifth and subsequent pachinko balls are ignored. When a normal winning hole sensor (not shown) detects a winning of a pachinko ball into the normal winning hole 18, ten prize balls are paid out. Moreover, the speaker 26 and the lamp 27 emit various sounds and lights according to the progress of the game to entertain the player.

The configuration and operation of the pachinko machine 10 have been briefly described above. Next, the configurations and operations of the main controller 100, the display controller 200, and the prize ball controller 300 that control the pachinko machine 10 will be described with reference to FIG. The main control unit 100 includes a CPU 102 (central processing unit), a ROM 104 (read-only memory) connected to the CPU 102 via a BUS 114 (information transmission circuit), an R

It is composed of a control circuit and the like, and its configuration is the same as that of the main control unit 100 and the display control unit 200, and therefore the description thereof is omitted here.

Then, when a pachinko ball is won in the first-type starting opening 30, whether it is a big hit or a miss, whether it is a certain change or a non-certain change,
The flow of the process that decides which symbol to stop,
This will be described with reference to the flowcharts of FIGS.
As shown in FIG. 4, first, it is determined whether or not a pachinko ball has won in the first type starting opening 30 (S12). This determination is made by setting “YES” if the main control unit 100 receives the detection signal from the starting opening sensor 56 of the first type starting opening 30 and “NO” if not receiving the detection signal. When the pachinko ball has won the first type starting opening 30 (in the case of “YES” in S12), the process proceeds to S14. When it is determined in S12 that the pachinko ball has not won in the first type starting opening 30 (in the case of NO), S14 to S20 described later are all skipped.

In S14 following S12, it is determined whether or not the number of reserved balls exceeds the upper limit value of 4. When it is determined in S14 that the number of reserved balls does not exceed 4 (in the case of NO), the process proceeds to S15. S14
If it is determined that the number of reserved balls exceeds four (YE
In the case of S), S15 to S18 are skipped. S1
In 5, the jackpot determination random number and the jackpot symbol random number are acquired. Here, the jackpot determination random number is a random number for determining whether or not it is a jackpot. The jackpot determination random number also determines whether the game state is switched to the probability variation state or the non-probability variation state. The jackpot symbol random number is a random number for determining the variable symbol displayed on the symbol display device 22 when the jackpot determination random number determines that it is a jackpot, and the stop symbol (jackpot symbol) displayed after that. S15
After the processing of S16, S16 is executed.

At S16, 1 is added to the number of reserved balls and this value is stored. Then, the process proceeds to S18, 1 is added to the planned fluctuation number, and this value is stored. The planned number of fluctuations is the number of symbol fluctuations that are planned to change at that time, and includes those during symbol fluctuations. The number of reserved balls and the planned number of fluctuations are respectively stored in the RAM 206 of the display control unit 200 (the number of reserved balls and the planned number of fluctuations will be described in detail later with specific examples). When the process of S18 ends, the hit determination process (No. 1) (S20) is executed.

In the hit determination process (No. 1) (S20) shown in FIG. 5, it is first determined whether or not the number of reserved balls is 1 or more (S32). The number of reserved balls is 1 in S32.
If it is determined that the above is the case (YES), S
In step 34, the jackpot determination random number and the jackpot symbol random number are read, and the hit determination process (No. 2) (S35) shown in FIG. 6 is executed. When it is determined in S32 that the number of reserved balls is not 1 or more (in the case of NO), the hit determination process (No. 1) S20 is ended.

In the hit determination process (part 2) (S35) shown in FIG. 6, it is first determined whether or not it is a big hit (S36). Specifically, the jackpot determination is performed by comparing the jackpot determination random number read in S34 of the hit determination process (No. 1) (S20) with a preset jackpot value to determine whether or not they match. That is. If they match, it is determined to be a big hit, and if they do not match, it is determined to be out. When it is determined that the jackpot is a big hit in S36 (YES), the big hit flag is turned on in S38, and the big hit symbol random number is read in S40. Further, whether the jackpot is a probability variation jackpot or a non-determination variation jackpot is determined by a jackpot symbol random number. Switching to a certain variation state or a non-certain variation state of the game state is performed when the jackpot symbol is stopped and displayed on the symbol display device 22. When the gaming state is the probability variation state, the number of jackpot values is set to be larger than that in the non-probability variation state. For example, the jackpot value is set to eight in the probability variation state, and is set to two in the non-probability variation state. Therefore, the probability variation state has a higher probability of a big hit than the non-probability variation state.

On the other hand, when it is determined in S36 that the jackpot is not a big hit (in the case of NO), the process goes to S42 and the jackpot flag is turned off. Then, the hit determination process (No. 2) S35 ends. In S46 following S40, it is determined whether or not it is a probability variation big hit. Whether or not this is the probability variation jackpot is determined by the jackpot symbol random number read in S34, as described above. S4
When it is determined that the probability variation jackpot is 6 (YES), the process proceeds to S48 and the probability variation flag is turned on. Then, in subsequent S50, 1 is added to the probability variable and stored. On the other hand, if it is determined in S46 that it is not the probability variation jackpot (in the case of NO), the non-probability variation flag is turned off in S52, and 1 is added to the non-probability variable in S54 and stored. The probable variable and the non-probable variable are stored in the RAM 206 of the display control unit 200, respectively.

After the processing of S50 or S54 is completed, the hit determination processing (No. 2) S35 is ended, and the hit determination processing (No. 1) S20 S55 of FIG. 5 is executed. In the following description, it is assumed that the expected number of fluctuations, the number of reserved balls, the probability variable, and the indeterminate variable are stored in the A block, and the jackpot determination random number and the pattern random number, which will be described later, are stored in the B block. The B block has five storage areas numbered 0 to 4 (the configurations of the A block and the B block will be described in detail later).

In S55 shown in FIG. 5, a big hit determination random number and a big hit design random number are stored. The jackpot determination random number and the jackpot symbol random number to be stored are stored in an area having a number corresponding to the number of reserved balls at that time (for example,
When the number of reserved balls is 1, the jackpot determination random number and the jackpot symbol random number are stored in the first area). After executing S55,
The process proceeds to S56, and the symbol variation pattern is determined. The determination of the symbol variation pattern is to determine the variable symbol displayed on the symbol display device 22 based on the jackpot symbol random number read in S40 and the stop symbol subsequently displayed. Specifically, in the case of a big hit, the symbol variation pattern determined from the big hit symbol random number is displayed on the symbol display device 22 as it is. If the jackpot is not a big hit, the symbol variation pattern up to the miss symbol and the miss symbol are determined by the offset symbol counter, and these are displayed on the symbol display device 22. S58 following S56
Then, the symbol variation command is output from the display control unit 200 to the symbol display device 22, and the symbol is displayed on the symbol display device 22.

When S58 ends, the process proceeds to S60, and it is determined whether or not the symbol variation has started. When it is determined in S60 that the symbol variation has started (YES), S62 is executed and 1 is subtracted from the number of reserved balls. When it is determined in S60 that the symbol variation has not started (in the case of NO), the process waits in that state. S62
In subsequent S64, the jackpot determination random number and the pattern random number of the B block are shifted to the smaller one area number (for example, the jackpot determination random number and the symbol random number stored in the first area and the second area are shifted. Then, the jackpot determination random number and the pattern random number are stored in the 0th area and the 1st area). In subsequent S66, it is determined whether or not the symbol has stopped. When it is determined in S66 that the symbol has stopped (YES), S68 is executed. When it is determined that the symbol is not stopped in S66 (in the case of NO)
To wait in that state.

In S68 subsequent to S66, it is determined whether or not the jackpot flag is "ON". This determination is made in S38 (big hit flag "on") or S42.
It is performed based on the flag set by (big hit flag “off”). When it is determined in S68 that the jackpot flag is "on" (in the case of YES), jackpot processing S70 is performed. When the big hit process is performed, the opening / closing door 36 of the special winning opening 34 is opened, so that many prize balls are paid out. After executing the jackpot process S70, the process proceeds to the abnormality detection process S80 (FIG. 6). Then, the abnormality detection process S80
After that, the hit determination process (1) (S20)
To finish. On the other hand, the jackpot flag is “ON” in S68.
When it is determined that it is not (NO, that is, when the jackpot flag is “OFF”), the process proceeds to S72 and the removal process is executed. When the removal processing is executed, the opening / closing door 36 of the special winning opening 34 is not opened. Then, the hit determination process (No. 1) (S20) ends.

In the abnormality detection processing S80 shown in FIG. 7, 1 is subtracted from the expected fluctuation number in the first step S82, and the jackpot determination random number stored in the 0th area of the B block is determined in S84. The design random number is cleared. Then, in S86 subsequent to S84, 1 is subtracted from the certain variable or the uncertain variable. In this S86, if the symbol variation stopped before that is a probability variation jackpot, it is subtracted from the probability variable, and if the stopped symbol variation is an uncertain variation jackpot, it is subtracted from an uncertain number. Then, the process proceeds to S88.

In the determination of S88, S90 and S92 described below, the consistency of the values of the A block and the B block is determined. When it is determined that there is no consistency, it is determined that the memory has been rewritten due to the influence of noise, etc., these values are initialized, the control of the pachinko machine 10 is stopped, and the game does not proceed any further. To In S88, it is determined whether or not the sum of the definite variable and the uncertain variable stored in the A block is equal to the number of jackpot determination random numbers that are the jackpots stored in the B block. When it is determined in S88 that the sum of the probabilistic variable and the non-probable variable is equal to the number of jackpot determination random numbers that are jackpots (in the case of YES),
S90 is executed. When NO is determined in S88, the process proceeds to S94 and game information (scheduled number of fluctuations, number of reserved balls, certain variable, non- certain variable, jackpot determination random number, symbol random number)
Is initialized and the control of the pachinko machine 10 is stopped to prevent the game from further progressing. Then, the abnormality detection process S80 ends.

In S90 subsequent to S88, it is determined whether the planned fluctuation number stored in the A block is equal to the number of areas in which the B block is stored (the big hit determination random number and the symbol random number are stored). To be determined. When it is determined in S90 that the planned fluctuation number and the area number are equal (YES
In the case of), S92 is executed. If NO is determined in S90, the process proceeds to S94 to initialize the game information, stop the progress of the game, and perform the abnormality detection process S80.
To finish. In S92, it is determined whether or not the area in which the B block is stored is continuous. S92
If it is determined that the area of the B block is continuously stored in the case (YES), the abnormality detection processing S80
To finish. When it is determined in S92 that the area of the B block is not continuously stored (in the case of NO),
The process proceeds to S94 to initialize the game information and stop the progress of the game. Then, the abnormality detection process S80 ends.

If it is determined in the abnormality detection processing S80 that there is an abnormality, and the probability variable and the probability variable are within a predetermined number, it is determined that the probability variable and the probability variable are correct. It can be configured to correct the planned number of fluctuations, the number of reserved balls, the jackpot determination random number, and the symbol random number. Also, when it is determined that it is also abnormal, if the value of the jackpot determination random number and the pattern random number is within the predetermined number, the jackpot determination random number and the symbol random number are correct, and the planned fluctuation number from these values, the hold It can also be configured to correct the number of spheres, the probable variable, and the non-probable variable (for the correction of each value when it is determined to be abnormal, a specific example in which each value of the A block and the B block described later changes) Inside, I will explain in detail).

Further, when it is determined to be abnormal in the abnormality detection processing S80, the game progress is stopped, and if the planned fluctuation number at that time is within a predetermined number (for example, 5 or less), The value may be displayed on the symbol display device 22 to notify the value. For example, when the planned number of fluctuations 4 is displayed on the symbol display device 22 and the progress of the game is stopped, when the game is restarted, the clerk in the hall puts four pachinko balls into the first-type starting opening 30. . This makes it possible to alleviate the player's dissatisfaction with the stop of the game. The above 5 pieces are set as numbers that do not burden the hole even if a prize is won.
It should be noted that the notification of the planned fluctuation number when it is determined to be abnormal in S80 can be performed by, for example, the number of lamps turned on or voice.

Next, the processing in the case where the power supply to the pachinko machine 10 is cut off and the pachinko machine 10 is restored thereafter will be described with reference to the flowcharts of FIGS. When the power supply to the pachinko machine 10 is cut off, the power cut-off process S110 shown in FIG. 8 is executed. In the power-off process S110, first, the determination value A is calculated (S112). The calculation of the discriminant value A is the expected number of fluctuations of the A block, the number of reserved balls,
It is to add a certain variable and an uncertain variable. Continued S11
In 4, the discriminant value B is calculated. The calculation of the determination value B is to add the jackpot determination random number and the pattern random number stored in each area of the B block. And S11
Going to 6, planned number of fluctuations, number of reserved balls, probability variable, indeterminate variable, jackpot judgment random number, symbol random number, judgment value A, judgment value B
Is backed up (the discriminant value A and discriminant value B that have been backed up are the old discriminant value A and the old discriminant value B, respectively).
These values are backed up in the RAM 206 of the display control unit 200. After executing S116, the power-off process is ended.

When the power supply to the pachinko machine 10 is restored, the power restoration procedure S120 shown in FIG. 9 is performed. S122, which is the first process of the power restoration process S120
Then, the planned number of fluctuations that were backed up, the number of holding balls,
From positive variable, non-positive variable, jackpot judgment random number, random pattern,
Reset the values of blocks A and B. Continued S
At 124, the discriminant value A and the discriminant value B are recalculated (the recalculated discriminant value A and discriminant value B are referred to as a new discriminant value A and a new discriminant value B, respectively). S126 that follows S124
Then, it is judged whether or not the newly calculated new judgment value A is equal to the backed up old judgment value A, and the newly calculated new judgment value B is equal to the backed up old judgment value B. To be done. If YES is determined in S126, there is no change in the planned number of fluctuations, the number of reserved balls, the probability variable, the non-accuracy variable, the jackpot determination random number, and the symbol random number when the power supply is cut off and after the power supply is restored. I can judge that
The game proceeds by shifting to 132 and restarting the control of the pachinko machine 10. Then, the power restoration process 120
To finish. If NO in S126, S
By shifting to 128 and stopping the control of the pachinko machine 10, the game is prevented from proceeding. Then, the power restoration process S120 ends. In addition, when the progress of the game is stopped in S128, it may be configured to clear the planned fluctuation number, the number of holding balls, the probability variable, the indeterminate variable, the jackpot determination random number, and the symbol random number.

Subsequently, the expected number of fluctuations, the number of reserved balls, a certain variable, an indeterminate variable stored in the A block, and the values of the jackpot determination random number and the pattern random number stored in each area of the B block change. An example will be described with reference to FIGS. 10 to 28, the A block is shown on the left side and the B block is shown on the right side. The B block is divided into areas numbered 0 to 4, and a jackpot determination random number and a symbol random number can be stored in each area. FIG. 10 shows a state before the pachinko ball wins the first type starting opening 30, and all values are initial values. A case will be described in which the first-type starting opening 30 is won and the winning is a jackpot of a certain change. The jackpot determination random number is 7, the jackpot random number is 1 (stop symbol "1.1.
Random number to 1 ”). When a prize is awarded to the first-type starting opening 30, as shown in FIG.
1 is added to each of the number of reserved balls and the probability variable. Since the number of reserved balls is 1, the jackpot determination random number 7 and the symbol random number 1 are stored in the No. 1 area corresponding thereto.

When the symbol variation is started, the number of reserved balls is subtracted by 1 and becomes zero as shown in FIG. Further, the jackpot determination random number 7 and the symbol random number 1 stored in the No. 1 area are shifted and moved to the No. 0 area. In this state, it is assumed that the first-class starting opening 30 is won, and the result is missed. The jackpot determination random number is 4 (a value that is out of range),
Design random number is 3 (random number to make the stop design "3, 3, 3")
And At this time, as shown in FIG.
1 and 2 are added to the planned number of fluctuations and the number of reserved balls, respectively.
become. Then, since the number of reserved balls becomes 1, 4 is stored in the jackpot determination random number of the 1st area corresponding thereto, and 3 is stored in the symbol random number. Further, it is assumed that a prize is awarded to the first-type starting opening 30 and that the prize is an uncertain jackpot. The jackpot determination random number is 9, the symbol random number is 6 (stop symbol "6.6
・ Random number to "6"). In this case, as shown in FIG. 14, 1 is added to the planned fluctuation number, the reserved sphere number, and the indeterminate variable to be 3, 2, and 1, respectively. And
The jackpot determination random number in the second area becomes 9, and the symbol random number becomes 6.

When the fluctuation of the symbol is temporarily stopped, as shown in FIG. 15, the planned fluctuation number is subtracted by one to become two. Since the stopped symbol fluctuation corresponded to the probability variation jackpot, the probability variable is subtracted by 1 and becomes zero. The jackpot determination random number and the pattern random number stored in the 0th area are cleared. Subsequently, when the symbol variation that is out of alignment is started, the number of reserved balls is decremented by 1 and becomes 1 as shown in FIG. 16, and the jackpot determination stored in the first area and the second area is determined. The random number and the pattern random number are shifted and moved to the 0th area and the 1st area. When the symbol stops, as shown in FIG. 17, the planned fluctuation number is decremented by 1 to 1. Since the stopped symbol fluctuation corresponded to the deviation, the uncertain variable is not subtracted. The jackpot determination random number and the pattern random number stored in the 0th area are cleared.

Next, when the symbol fluctuation which is an uncertain variation jackpot is started, as shown in FIG. 18, the number of reserved balls is decremented to zero. Further, the jackpot determination random number and the pattern random number stored in the No. 1 area are shifted and moved to the No. 0 area. Then, when the symbol fluctuation stops, FIG.
As shown in, the expected fluctuation number is subtracted by 1 to become zero. Since the stopped symbol fluctuation corresponded to the uncertain variation jackpot, the uncertain variable is subtracted by 1 and becomes zero. The jackpot determination random number and the pattern random number stored in the first area of the B block are cleared. In this way
Each value of the A block and the B block returns to the initial value.

Next, the abnormality detection performed using the values of the A block and the B block will be described. This abnormality detection is determined to be abnormal when the following (1) to (3) are not satisfied, as already described in S88, S90, and S92 of the flowchart of FIG. 7. (1) Is the sum of the probabilistic variable and the non-probable variable equal to the number of jackpot determination random numbers for a hit? . (2) Is the planned number of fluctuations equal to the number of areas where B blocks are stored? . (3) Is the area where B blocks are stored continuous? . In (1), it may be determined to be abnormal when the difference between the sum of the probabilistic variables and the non-probable variables and the number of the jackpot determination random numbers is a predetermined number or more. Also in (2), it may be determined to be abnormal when the difference between the planned number of fluctuations and the number of areas in which the B block is stored is a predetermined number or more.

Referring to FIG. 15, the above (1)-
The case where the determination of (3) is established will be described. In FIG. 15, since the probability variable of block A is zero and the probability variable is 1, the sum of these is 1. The jackpot determination random number for the jackpot of B block is only one stored in the second area. Therefore, the above (1) is established. The planned number of fluctuations is 2, and the number of areas in which the B block is stored is the first area and the second area, so the number is two. Therefore, the above (2) is established. In block B, storage is continuously performed in area 1 and area 2. Therefore, the above (3) is established.

A case where the above (1) to (3) are not established will be described with reference to FIGS. In FIG. 20, the probability variable of the A block is zero, the probability variable is 1, and the sum of these is 1. There are two jackpot determination random numbers that are jackpots for the B block, which are stored in areas 0 and 1, respectively. Therefore, the above (1) is not established and is determined to be abnormal. In FIG. 21, the planned change number is 2, and the number of areas in which the B block is stored is three, that is, the 0th area, the 1st area, and the 2nd area.
Therefore, the above (2) is not established and is determined to be abnormal. In FIG. 22, in block B, the 0th area, the 1st area, and the 3rd area are stored, and the 1st area and the 3rd area are vacant and discontinuous. Therefore, the above (3) is not established and is determined to be abnormal.

As described above, when it is determined to be abnormal in the abnormality detection processing, it is possible to modify other values from the probability variable and the indeterminate variable, or the jackpot determination random number and the pattern random number. A specific example of this modification will be described.
First, an example of correcting other values from the probable variable and the non-probable variable will be described. In the pachinko machine 10 of the present embodiment, if the probability variable and the non-probability variable of the A block are each within 3 when it is determined to be abnormal, the estimated variable number, the number of reserved balls, Correct the jackpot determination random number and the pattern random number. That is, even if it is determined that there is an abnormality, if the probability variable and the probability variable are within 3, the probability variable and the probability variable are regarded as correct and other values are corrected.

As shown in FIG. 23, in the B block, the big hit determination random number and the symbol random number are stored in the 0th area and the 2nd area, but not continuously stored in the area. Therefore, it is determined to be abnormal. In this case, the probability variable is 1 and the probability variable is 0, which is within 3, so that the expected variation number, the reserved ball number, the jackpot determination random number, and the symbol random number are corrected using these values. The corrected result is shown in FIG. Since the probability variable which is the basis for correction is 1, the planned fluctuation number and the reserved ball number are respectively corrected to 1 so that one symbol fluctuation is performed. Then, the jackpot determination random number of the No. 1 area corresponding to the number of reserved balls of 1 is corrected to 9, and the symbol random number is corrected to 1 corresponding to the probability change.

As the value for correcting the area of the B block, a plurality of jackpot determination random numbers and symbol random numbers in which the order of correction corresponding to positive and negative changes are set are prepared. For example, in response to a non-probable change, "big hit determination random number 7,
Design random number 2 "," Big hit determination random number 9, Design random number 6 ",
"Big hit determination random number 4, symbol random number 3" is prepared, and when correcting based on the uncertain variable 2, the area of the B block is "big hit determination random number 7, symbol random number 2", "big hit determination random number 9". , Random number 6 ”.

An example of correcting another value from the jackpot determination random number and the pattern random number will be described. Pachinko machine 10 of the present embodiment
Is, if the jackpot determination random number stored in each area of the B block is 631 or less and the symbol random number is 100 or less when it is determined to be abnormal, from the jackpot determination random number and the symbol random number, the planned fluctuation number, the hold Correct the number of spheres, the probable variable, and the indeterminate variable. As shown in FIG. 25, 86 is stored in the exact variable and 1 is stored in the inexact variable of the A block. The sum of the probable variables and the non-probable variables is 87, which is different from the number 1 of the jackpot determination random numbers for the jackpot of the B block. Therefore, it is determined to be abnormal. In this case, the jackpot determination random number of the 0th area of the B block is 7, the symbol random number is 1, the jackpot determination random number of the 1st area is 4, and the symbol random number is 3, so the above jackpot determination random number 631 or less, the symbol It is a value within a random number 100. Therefore, assuming that the jackpot determination random number and the pattern random number stored in the 0th area and the 1st area of the B block are correct, the planned number of fluctuations, the number of reserved balls, based on these values,
Correct the positive and negative variables. FIG. 26 shows the corrected result.
Shown in. Since the number of areas in which the big hit determination random number and the pattern random number of the B block which is the basis for correction are stored are two, the planned fluctuation number and the number of reserved balls are corrected to 2, respectively. And the jackpot random number is 1, which corresponds to the probability change, so the probability variable of the A block is corrected to 1.

An example of the operation when the power supply to the pachinko machine 10 is cut off and then restored will be described. As described above, when the power supply to the pachinko machine 10 is cut off,
The planned number of fluctuations of the A block, the number of reserved balls, the probability variable, the non-accurate variable, and the sum (discrimination value A) thereof are backed up. Also, the sum of the jackpot determination random number of B block and the symbol random number (determination value B) is backed up. When the power supply is restored, the discriminant value A and the discriminant value B are recalculated from the backed up values. Then, the recalculated discriminant value A and discriminant value B are backed up to discriminant value A and discriminant value B.
If it matches with, it is normal, and if it does not match, it is judged that the backed up value has been rewritten and abnormal.

For example, when the power supply is cut off in the state shown in FIG. 27, the expected number of fluctuations in the A block, the number of reserved balls, the certainty variable, the uncertainty variable, and the jackpot determination of the 0th area of the B block are determined. Random numbers and random symbols are backed up.
Also, the discriminant value A and the discriminant value B are calculated and backed up. When the power supply is restored, as shown in FIG. 28, the planned number of fluctuations that have been backed up, the number of holding balls,
The values of the definite variable, the definite variable, the jackpot determination random number, and the symbol random number are reset. Then, the judgment value A and the judgment value B are recalculated from these values. In FIG. 28, the value of the number of reserved balls changes between when the power supply is cut off and after the power supply is restored (1 → 99). Therefore, the discriminant value A is 102, which does not match 5 when the power is turned off. Therefore, it is determined to be abnormal. The determination value B is 15 when the power supply is cut off and after the power supply is restored, and is not changed.
Therefore, it can be determined that the value of the B block is correct.
A block may be restored based on the block.

When the power supply is cut off and the power is restored after that, the abnormality judgment is normal even if the old and new discriminant values A and B do not completely coincide with each other within a predetermined number. It can also be configured to make a judgment. In addition, the abnormality determination when the power supply is cut off and then restored is determined by the determination value A
Instead of performing the judgment value B based on whether the judgment value B is new or old, the judgment value A and the judgment value B recalculated may be matched. Also,
The calculation of the discriminant value A and the discriminant value B is not limited to the sum. For example, the difference may be calculated or the product may be calculated.
Also,
