Description

  The present invention relates to a gaming machine, and more particularly to a technique for detecting an abnormality of a hard random number.

  In recent years, in the mainstream pachinko machines, a big hit lottery is performed when the game ball wins the starting opening, and when it wins there, a big hit game in which the big winning opening opens and closes over multiple rounds occurs . In this type of pachinko machine, a hard random number generation circuit is generally provided, and a hard random number for determining a big hit is acquired from the hard random number generation circuit when a game ball is won at the starting port. Whether or not a big hit lottery is won is determined.

  Even in conventional slot machines, generally, a hard random number for determining a big hit is acquired from a hard random number generation circuit when a start lever is operated after a medal bet, and whether or not a big hit lottery is won is determined based on whether or not the hard random number is a specific value for the big hit. Is done. In the case of a slot machine, a bonus game in which a specific symbol combination is easily arranged over a plurality of games occurs when winning a big hit lottery. The jackpot winning probability is determined by the number of jackpot specific values for the total number of hard random numbers that can be generated by the hard random number generating circuit.

  By the way, when there is an abnormality in the hard random number acquired from the hard random number generation circuit due to a failure of the hard random number generation circuit, a disconnection of the communication line, or the like, the big hit determination cannot be performed normally. Therefore, the following technique for detecting an abnormality of a hard random number is known.

  In the technology described in Patent Document 1 (pachinko machine), the hard random number obtained this time and the hard random number obtained last time obtained by winning the game ball at the starting port are compared. It is determined whether or not all 16 bits, upper bits, and lower bits constituting the same match, and when the number of matches reaches the set number, the abnormality notification lamp is turned on.

  In the technique (slot machine) described in Patent Document 2, a hard random number is acquired every minute time during one game (during one game execution), and the 16 bits constituting the hard random number for the plurality of acquired hard random numbers. It is determined whether or not both 0 and 1 have been confirmed in each of the bits, and if there is a bit for which neither 0 nor 1 has been confirmed, error processing is executed.

  As shown in FIG. 4, the main control device 21 (game control board 22) includes a random number generation means 40, a random number acquisition means 41, a random number determination means 42, and a random number abnormality detection means 50. The random number generation means 40 is configured by a hard random number generation circuit of the game control board 22, and the other means 41, 42, and 50 are configured by the CPU, ROM, and RAM of the game control board 22.

The random number generation means 40 generates a 16-bit hard random number that is a big hit random number for big hit determination. In this case, a hard random number is generated while being randomly updated within a range of 0 to 65535 every minute time (0.1 μs) (first minute time) . That is, the total number of hard random numbers that can be generated by the random number generation means 40 is 65536.

  The random number acquisition unit 41 acquires a hard random number from the random number generation unit 40. In this case, when the predetermined condition (the first or second hold number is less than 4) is established at the timing when the game ball is won in the first or second starter 10 or 11a, Get a random number.

The random number determination unit 42 determines the hard random number acquired by the random number acquisition unit 41. In this case, it is determined whether or not the big hit random number (hard random number) acquired by the random number acquisition means 41 is a preset big hit specific value. 205 big hit specific values are set, and the ratio of the number of big hit specific values to the total number of big hit random numbers (65536) that can be generated by the random number generating means 40 is about 1/320. In other words, the jackpot determination is made with a probability of about 1/320. Note that the hard random numbers acquired by the random number acquisition unit 41 are sequentially determined by the random number determination unit 42 and, therefore, are temporarily stored in the RAM until at least the determination by the random number determination unit 42.

  The random number abnormality detecting means 50 is specific to the present scheme for detecting an abnormality of a hard random number, and includes a random number acquisition unit 51, a random number determination unit 52, an abnormality determination unit 53, and first and second storage units 54 and 55.

The random number acquisition unit 51 sequentially acquires a plurality of hard random numbers from the random number generation means 40. In this case, apart from the random number obtaining unit 41 obtaining the hard random number from the random number generating unit 40, the hard random number is obtained from the random number generating unit 40 every minute time (4 ms) (second minute time) . When a big hit random number is acquired every 4 ms, 100,000 big hit random numbers can be acquired in 400 seconds.

  The random number determination unit 52 determines whether each hard random number (big hit random number) acquired by the random number acquisition unit 51 is a preset specific value (a big hit specific value in the normal gaming state and the short-time gaming state). Similar to the probability of the jackpot determination by the random number determination means 42, the specific value is determined with a probability of about 1/320.

  When the number of hard random numbers acquired by the random number acquisition unit 51 reaches a predetermined number, the abnormality determination unit 53 generates the number of hard random numbers determined by the random number determination unit 52 as a specific value in the random number generation means 40 It is determined whether the number is within a set range determined based on the ratio of the number of specific values to the total number of possible hard random numbers.

  In other words, when the number of hard random numbers acquired by the random number acquisition unit 51 reaches a predetermined number, the abnormality determination unit 53 determines the hard random number determined as a specific value by the random number determination unit 52 for the predetermined number. It is also determined whether or not the ratio of the number is within a set range determined based on the ratio of the number of specific values to the total number of hard random numbers that can be generated by the random number generation means 40.

  Specifically, when the number of jackpot random numbers acquired by the random number acquisition unit 51 reaches 100,000, which is greater than or equal to the total number of jackpot random numbers (65536) that can be generated by the random number generation means 40, the random number determination unit 52 The number of jackpot random numbers determined to be the jackpot specific value is determined based on the ratio (about 1/320) of the number of specific values (205) to the total number of jackpot random numbers (65536) that can be generated by the random number generating means 40. It is determined whether the number is within the set range (156 (≈100,000 × 205/65536 × 1/2) to 626 (≈100,000 × 205/65536 × 2)).

  The first storage unit 54 stores the random number acquisition number of the hard random number acquired by the random number acquisition unit 51, and the second storage unit 55 stores the specific value of the hard random number determined as the specific value by the random number determination unit 52 The number of judgments is stored. And the abnormality determination part 53 performs said determination based on the information of the 1st, 2nd memory | storage parts 54 and 55. FIG.

  Further, when the number of hard random numbers stored in the first storage unit 54 reaches a predetermined number (100,000), the main control device 21 stops the acquisition of the hard random number by the random number acquisition unit 51 and the first , The information in the second storage units 54 and 55 is reset, and thereafter, when a certain condition is satisfied, the acquisition of the hard random number by the random number acquisition unit 51 is started. Specifically, this certain condition is established when a certain time (one hour) has elapsed.

  When the abnormality determination unit 53 makes a negative determination, the main control device 21 outputs random number abnormality information to the sub-control device 25, and when the sub-control device 25 receives random number abnormality information from the main control device 21. Then, the notification device 58 is controlled to notify the abnormality of the hard random number. Specifically, the notification device 58 includes at least one of the image display 16, the speaker 34, the frame lamp 35, and the panel lamp 36.

  Further, when the abnormality determination unit 53 makes a negative determination, the main control device 21 outputs random number abnormality information to the hall computer 59, which is an external data processing device, via the board external information terminal board 23. When the random number abnormality information is received from the main control device 21, the pachinko gaming machine 1 having an abnormality in the hard random number is identified and notified.

Here, the big hit random number determination table shown in FIG. Based on the acquired big hit random number of the second reserved random number, and in the case of via S36, it is determined whether or not it is a big hit based on the first acquired big hit random number of the first held random number. It is determined whether or not it is a small hit.

  In the jackpot random number determination table of FIG. 9, in the normal gaming state and the short-time gaming state, the number (205) of jackpot specific values corresponding to the ratio of about 1/320 of the total number of jackpot random numbers (65536) is set. In the probability variation gaming state and the latent probability gaming state, a number (2050) of jackpot specific values corresponding to a ratio of about 1/32 of the total number of jackpot random numbers is set. Whether or not a big hit is determined by whether or not.

  In the four gaming states, a small hit specific value other than the big hit specific value corresponding to a ratio of about 3/320 of the total number of big hit random numbers (615) is set. Whether or not the small hit is determined by whether or not the small hit specific value.

  As shown in FIG. 8, in the case of big hit (S52; Yes), in the case of via S34, as the second special symbol, based on the big hit symbol random number of the second reserved random number acquired first, In the case of passing through S36, five types of jackpot symbols, a probability variation symbol, a time-short symbol, a random symbol symbol, and a latent symbol symbol, are used as the first special symbol, based on the jackpot symbol random number of the first reserved random number acquired first. Any one is selected and set (S54). In the case of small hit (S52; No, S55; Yes), a small hit symbol is set (S56), and in the case of no small hit (S52; No, S55; Yes), that is, in the case of a loss, a lost symbol is set ( S57).

  Here, in the case of a big hit, the big winning prize opening 13a is in a big hit gaming state that opens and closes over a plurality of rounds, and then, if a big hit is made in the probability variation symbol and the sudden probability symbol, it shifts to a probability variation gaming state, and the time-saving symbol When a big hit is made, the game shifts to a short-time gaming state, and when a big hit is made with the latent pattern, the game moves to the latent gaming state. In addition, after the transition to the short-time gaming state, after the big hit random number determination process of S51 (that is, the special symbol variation) is performed 100 times (or several tens of times), the normal gaming state is entered. In the case of a small hit, the current gaming state is maintained.

  As shown in FIG. 7, in the variation pattern selection process in S39, a variation pattern (variation time) is selected and set for the game effect from the type of special symbol set in S38. Thereafter, the first or second special symbol is started to vary (S40), and a variation start command including information on the type of the special symbol set in S38 and the variation pattern (variation time) set in S39 is set ( S41). In the case of S42; No, the process returns.

  Next, when the fluctuation time set in S39 has elapsed (S42; Yes), the first or second special symbol is suspended (S43), where the special symbol set in S38 is the first or first special symbol. 2Displayed on the special symbol display 19a or 19b. Subsequently, a change stop command is set (S44), a stop process (S45) is executed, and the process returns. In the in-stop process, a process for shifting the game state is executed.

  Next, the hard random number abnormality detection process in S6 will be described in detail with reference to FIGS. F1 is an abnormality detection execution flag, F2 is an abnormality detection end flag, F3 is an abnormality detection interruption flag, A is a random number acquisition number, B is a specific value determination number, T is an abnormality detection interruption timer, and these are all turned on. It shall be initialized to 0 at times.

  As shown in FIG. 10, in this hard random number abnormality detection process, it is first determined whether or not the abnormality detection execution flag F1 is 1 (S61). In the case of S61; Yes, a hard random number (big hit random number) is acquired from the hard random number generation circuit (S62), and the random number acquisition number A is added to A + 1 (S63). In S62, when a hard random number is generated in S14 or S19 of FIG. 6, the hard random number may be used, or a separate hard random number may be acquired. Next, it is determined whether or not the hard random number acquired this time is a specific value (a big hit specific value in the normal gaming state and the short-time gaming state) (S64). If S64; Yes, the specific value determination number B is added to B + 1. (S65).

  S64: After No or S65, it is determined whether A = X (100,000) (S66). S66: If Yes, it is determined whether Y (156) ≦ B ≦ Z (626) or not (S67). S66; If No, return. S67; If No, a random number abnormality command is set (S68). This random number abnormality command is output to the sub-control device 25 and also to the hall computer 59 in the output process of S7.

  S67; Yes or after S68, the abnormality detection end flag F2 is set to 1 (S69), F1, A, and B are all reset to 0 (S70), and the process returns. On the other hand, in the case of S61; No, a random number abnormality detection start determination process (S71) is executed, and the process returns.

  As shown in FIG. 11, in the random number abnormality detection start determination process in S71, it is first determined whether or not the abnormality detection interruption flag F3 is 1 (S81). S81: If No, it is determined whether or not the abnormality detection end flag F2 is 1 (S82). S82: If Yes, F2 is reset to 0 (S83), the abnormality detection interruption flag F3 is set to 1 (S84), and then the abnormality detection interruption timer T is started (S85) and returns.

  On the other hand, if S81 is Yes, it is detected whether T ≧ Tc (1 hour) or not (S86). Note that Tc can be set (changed) as appropriate. S86: If Yes, the abnormality detection interruption timer T is reset to 0 (S87), and the abnormality detection interruption flag F3 is reset to 0 (S88). S86; If No, return. After S82; No or S88, the abnormality detection execution flag F1 is set to 1 (S89), and then the specific value setting process (S90) is executed.

  In the specific value setting process of S90, a process of setting the big hit specific value as the specific value is performed. In this embodiment, since the specific value setting process sets the big hit specific value in the normal gaming state and the short-time gaming state as the specific value every time, S90 can be omitted.

  As can be seen from the flowcharts shown in FIGS. 10 and 11, when the power is turned on, first, from the start of S6, S61; No-> S71-> S81; No-> S82; No, so in S89, the abnormality detection execution flag F1 is set. Therefore, since S61; Yes → S62 →... From the start of the next S6, processing for obtaining and determining a hard random number is performed in order to determine an abnormality of the hard random number immediately after the power is turned on. Is executed.

  Once S61; Yes, S61 to S66 are repeatedly executed from the start of S6 every 4 ms until the random number acquisition number A reaches 100,000, and the abnormality detection execution flag F1 is set to 1. 400 seconds later, when the random number acquisition number A reaches 100,000, S66; Yes, whether there is an abnormality in the hard random number based on the random number acquisition number A and the specific value determination number B Determined.

  After the random number acquisition number A reaches 100,000 and it is determined whether or not there is an abnormality in the hard random number, the abnormality detection end flag F2 is set to 1 in S69, and the abnormality detection execution flag F1 is 0 in S70. Reset to. Therefore, from the start of the next S6, S61; No → S71 → S81; No → S82; Yes →..., The abnormality detection end flag F2 is reset to 0 in S83, and the abnormality detection interruption flag F3 is set in S84. Set to 1. In S85, the abnormality detection interruption timer T is started.

  Therefore, from the start of the next S6, S61; No-> S71-> S81; Yes -------------------- The processing for determining acquisition of a hard random number is interrupted until the abnormality detection interruption timer T reaches 1 hour, S61. No → S71 → S81; Yes → S86; No is repeatedly executed. Then, when the abnormality detection interruption timer T reaches 1 hour, the abnormality detection execution flag F1 is set to 1 in S89. Therefore, from the start of the next S6, S61; Yes → S62 →. Then, processing for obtaining and determining a hard random number is executed.

  If the game ball wins the start opening 10 or 11a during the execution of the hard random number acquisition determination process shown in FIG. 10, the hard random number acquisition determination process in this actual game is performed. The hard random number acquisition determination process and the hard random number abnormality detection process are executed in parallel without mutual interference.

  Next, as shown in FIG. 12, in the timer interrupt process for every minute time (4 ms) on the effect control board 27, the command reception process (S101), the effect button process (S102), and the command transmission process (S103) are sequentially performed. Executed and returns.

  As shown in FIG. 13, in the command reception process of S101, when a pending number increase command is received (S111; Yes), a pending number addition process (S112) is executed and a pending number command is set (S113). . When the change start command is received (S114; Yes), the effect selection process (S115) is executed. When the change stop command is received (S116; Yes), the changing effect end process (S117) is executed. When the opening command is received (S118; Yes), a winning effect selection process (S119) is executed. When an ending command is received (S120; Yes), an ending effect selection process (S121) is executed. When the random number abnormality command is received (S122; Yes), the random number abnormality notification command is set (S123).

  The random number abnormality notification command set in S123 is transmitted to at least one of the image control board 28 and the lamp control board 29 in the command transmission process of S103. When the image control board 28 receives a random number abnormality notification command, the image display 16 displays a random number abnormality display (for example, “Random number abnormality present” is displayed on a part of the screen), and the lamp control board 29 displays a random number. When the abnormality notification command is received, the frame lamp 35 and the panel lamp 36 are turned on to indicate a random number abnormality (for example, special blinking different from the game effect). Finally, a customer waiting command reception process (S124) is executed, and the process returns.

The pachinko gaming machine 1 has the following effects.
The game control device 20 is provided with a random number abnormality detecting means 50 for detecting an abnormality of a hard random number. The random number abnormality detecting means 50 includes a random number acquisition unit 51, a random number determination unit 52, and an abnormality determination unit 53. However, when the number of hard random numbers acquired by the random number acquisition unit 51 reaches a predetermined number, the number of hard random numbers determined by the random number determination unit 52 as a specific value can be generated by the random number generation means 40. It is determined whether or not the number is within a set range determined based on the ratio of the number of specific values to the total number.

  That is, based on the ratio of the number of specific values to the total number of hard random numbers that can be generated by the random number generation means 40, the hard random numbers are abnormal from the number of hard random numbers actually acquired and the number determined as the specific value. It is possible to verify whether or not the performance of the pachinko gaming machine 1 including the original hard random number generation circuit is maintained. When there is an abnormality in the hard random number, it is improved so that the original performance of the pachinko gaming machine 1 can be obtained assuming that the random number generation means 40 (hard random number generation circuit) is faulty, the communication line is broken, or further illegal. Can be achieved.

  The random number abnormality detecting unit 50 stores a first storage unit 54 that stores the number of hard random numbers acquired by the random number acquisition unit 51 and a second storage that stores the number of hard random numbers determined by the random number determination unit 52 as a specific value. When the number of hard random numbers acquired by the random number acquisition unit 51 reaches a predetermined number, the abnormality determination unit 53 makes a determination based on the information in the first and second storage units 54 and 55. In addition, whether or not the number of hard random numbers determined to be the specific value by the random number determination unit 52 is within the set range can be reliably processed and determined.

  When the number of hard random numbers stored in the first storage unit 54 reaches a predetermined number, the acquisition of the hard random number by the random number acquisition unit 51 is stopped and the information in the first and second storage units 54 and 55 is reset. Then, since the acquisition of the hard random number by the random number acquisition unit 51 is started when a certain condition is satisfied, the hard random number acquisition determination and the subsequent abnormality determination are not performed continuously, but every time the certain condition is satisfied It can be executed intermittently and periodically checked to see if there are any abnormal hard random numbers.

  Since the main control device 21 is provided with the random number abnormality detection means 50 together with the random number generation means 40, the random number acquisition means 41, and the random number determination means 42, an increase in the load on the sub control device 25 can be suppressed. The main control device 21 outputs random number abnormality information to the sub-control device 25 when the abnormality determination unit 53 makes a negative determination, and the sub-control device 25 notifies when the random number abnormality information is received from the main control device 21. Since the hard random number abnormality is notified by controlling the device 58, the hard random number abnormality can be notified using the notification device 58 attached to the pachinko gaming machine 1. Further, when the abnormality determination unit 53 makes a negative determination, the main control device 21 outputs random number abnormality information to the external hall computer 59. Therefore, the hard random number is abnormal using the hall computer 59 installed in the game hall. A certain pachinko gaming machine 1 can be identified and notified.

  Here, in the main control device 21, when the abnormality determination unit 53 makes a negative determination, the process of outputting the random number abnormality command to the sub control device 25 is omitted, and the sub control device 25 receives the random number abnormality information from the main control device 21. In the case of receiving the notification, the process of controlling the notification device 58 to notify the abnormality of the hard random number may be omitted. Thereby, the load increase of the main control device 21 can be suppressed, the load increase of the sub-control device 25 can be eliminated, and further, the notification device 58 notifies the abnormality of the hard random number so as to make the player feel uneasy. Factors can be eliminated. Alternatively, in the main control device 21, when the abnormality determination unit 53 makes a negative determination, a random number abnormality command is output to the sub-control device 25, but the processing to be output to the hall computer 59 can be omitted.

  Since the random number generating means 40 generates a hard random number for determining the big hit, if there is an abnormality in the hard random number for determining the big hit, there is a disadvantage for the player or the game hall. By detecting an abnormality, it is possible to prevent a disadvantage from occurring in the player or the game hall. Since the specific value is a big hit specific value (a big hit specific value in the normal gaming state and the short-time gaming state) that is a big hit determination when determined by the random number determination means 42, the original big hit probability of the pachinko gaming machine 1 It can be verified whether or not is maintained.

  The random number acquisition unit 51 acquires a hard random number from the random number generation unit 40 every minute time (4 ms), and the predetermined number is a number equal to or greater than the total number of hard random numbers (65535) that can be generated by the random number generation unit 40 (100,000). Therefore, the determination of whether or not there is an abnormality in the hard random number by the abnormality determination unit 53 can be performed quickly and accurately.

  Next, a description will be given of the following embodiment in which the first embodiment is partially changed. Note that description of substantially the same as in the first embodiment will be omitted.

  As shown in FIG. 14, in this hard random number abnormality detection process, C represents the number of abnormality determinations, and is initially set to 0 when the power is turned on. In this hard random number abnormality detection process, in the case of S67; No, that is, when the specific value determination number B is not within the set range, the abnormality determination number C is added to C + 1 (S201). It is determined whether or not the set number of times is α (for example, α = 3 times) (S202). If S202; No, the process proceeds to S69. If S202; Yes, C is reset to 0 (S203), and then a random number abnormality command is set (S69).

  That is, when the number of negative determinations made by the abnormality determination unit 53 is not one time but multiple times, it is determined that there is an abnormality in the hard random number, and the random number abnormality command is sent to the sub-control device 25 and the hall computer 59. I am trying to output. This makes it possible to more reliably detect and notify whether there is an abnormality in the hard random number.

  The abnormality determination number C may be the number of times that the abnormality determination unit 53 continuously makes a negative determination. That is, if the determination is affirmative in the next determination in which the abnormality determination number C is added, C may be reset to zero. Thus, it can be expected to detect whether or not there is an abnormality in the hard random number with higher accuracy. When the abnormality determination number C is added, S61; Yes may be set immediately after the start of S6, and the process may proceed to S62.

  In the case of S202; No, the values of Y and Z may be changed. For example, normally, Y = 156 and Z = 626 are set, but when S202; No, Y is set to a value smaller or larger than 156 at normal time and Z is larger than 626 at normal time or A small value may be set. That is, each time the abnormality determination unit 53 makes a negative determination, the setting range can be changed so that an abnormality of the hard random number can be reliably detected.

  In the hard random number abnormality detection process of FIG. 10, S61, S69, and S71 (FIG. 11) are omitted, and in S70, the process of A, B ← 0 is executed. That is, it is possible to check whether or not there is an abnormality in the hard random number by continuously executing the acquisition determination of the hard random number and the subsequent abnormality determination. This can also be applied to the second embodiment. Note that the hard random number acquisition determination and the subsequent abnormality determination may be executed only once when the power is turned on.

  As shown in FIG. 15, in this hard random number abnormality detection process, after S61; Yes, whether or not the first or second starting port SW10a or 11c is ON (that is, S11 (S12) or S16 (S17); Whether or not Yes) is determined (S211). If S211; No, the process proceeds to S62, and if S211; Yes, the process returns. That is, it can be configured not to adversely affect hard random number acquisition in the actual game. This can also be applied to the second and third embodiments.

As shown in FIG. 16, in the specific value setting process of S90, N indicates the number of specific values determined, and is initially set to 0 when the power is turned on. In this specific value setting process, it is first determined whether or not the specific value determination number N is N _MAX (S221). If S211 is No, N is added to N + 1 (S222), and if S211 is Yes, N is set. 1 is set (S233). Then, after S222 or S223, the Nth specific value is set as the specific value (S224).

In the process of S224, the specific value setting table shown in FIG. 17 is used. In the specific value setting table, the specific values shown in the figure are associated with N ranging from 1 to N _MAX . For example, the specific value of group A when N is 2 is a set value (for example, 205) other than the big hit specific value, and the specific value of group B when N is 3 is the big hit specific value. And set specific values (for example, 205) other than the specific values of group A. Further, the specific value of group a when N is 12 is a specific value other than the jackpot specific value (for example, 2050), and the specific value of group b when N is 13 is the jackpot specific value And the set specific values (for example, 2050) other than the specific values of the group a.

  In order to detect a hard random number abnormality in the probability variation gaming state and the latent probability gaming state, the setting range is changed from the range in the normal gaming state and the short-time gaming state (for example, 156 to 626) to the probability variation gaming state and the latent probability. It is changed to the range in the gaming state (for example, 1560 to 6260: 10 times the range in the normal gaming state and the short-time gaming state). In this way, the total number of hard random numbers that can be generated by the hard random number generation means 40 can be determined, and if there is an abnormality in the hard random number, it is possible to specify which range of hard random numbers the hard random number is. Become.

  In the sixth embodiment, the set range (Y to Z) is determined using standard deviations calculated based on a large number of hard random number data acquired and collected from the random number generating means 40 in advance. Specifically, in one experiment, 100,000 hard random numbers are acquired from the random number generation means 40 (random number generation circuit), and it is determined whether each hard random number is a specific value (big hit specific value). The number of specific value judgments thus obtained is tabulated, and this experiment is tried a plurality of times (20 times).

  The random number generation means 40 (random number generation circuit) used here is the same as that mounted in the pachinko gaming machine 1, but it is assumed that a normal hard random number is generated. Further, for example, using a control board equivalent to the main control board 21 mounted on the pachinko gaming machine 1 including the random number generation means 40, acquisition determination of a hard random number is performed every 4 ms to collect data.

  18 and 19 show tables and graphs of the number of specific value determinations that are actual measurement values obtained in this experiment. In the 20th experiment, the maximum number of specific value determinations in the second experiment was 349 (about 1/287 in probability), and the minimum number of specific value determinations in the 6th experiment was 281 (approximately in probability). 1/356).

  As shown in FIGS. 20 and 21, an average value of the number of specific value determinations of 20 experiments: about 310 (about 1/323 with probability) is calculated from these data, and an ideal value of about 313 (≈100000). × 205/65536, the probability is lower than about 1/320). Moreover, the standard deviation: about 18.3 was calculated. Then, the minimum value Y and the maximum value Z of the set range (Y to Z) are determined as follows based on the average value, ideal value, and standard deviation.

  First, as shown in FIG. 20, the average is an actual measurement value (Xbar: about 310), and the range of Xbar ± 3σ (standard deviation: 18.3), that is, the range of about 255 to 365, Although about 99.7% is included, Xbar ± 6σ = about 419,200 is calculated, and these are set as candidates for the maximum value Z and the minimum value Y of the setting range. Next, as shown in FIG. 21, assuming that the average is an ideal value (Xbar: about 313), Xbar ± 6σ = about 423,203 is calculated, and these are set as candidates for the maximum value Z and the minimum value Y of the setting range. .

  Then, from the viewpoints of both the standard deviation and the actual measurement value and the ideal value, either the candidate shown in FIG. 20 or the candidate shown in FIG. 21 is set as the minimum value Y so that the setting range (Y to Z) is maximized. One (about 199 shown in FIG. 20) is selected and set, and as the maximum value Z, one of the candidates shown in FIG. 20 and the candidate shown in FIG. 21 (about 423 shown in FIG. 21) is selected and set. Thus, the set range (Y to Z) is determined using the standard deviation calculated based on the data of a large number of hard random numbers acquired and collected in advance from the random number generator 40, and the value deviating from this set range When it becomes, it becomes possible to judge that there is an abnormality in the hard random number.

  As shown in FIG. 20, the average is an actual measurement value (Xbar: about 310), and Xbar ± 3σ = about 365, 255 is set as a candidate for the maximum value Z and the minimum value Y of the set range, as shown in FIG. Assuming that the average is an ideal value (Xbar: about 313) and Xbar ± 3σ = about 368,258 is a candidate for the maximum value Z and the minimum value Y of the setting range, the setting range (Y to Z) is the maximum as described above. Thus, the minimum value Y (about 255 shown in FIG. 20) and the maximum value Z (about 368 shown in FIG. 21) may be selected and set.

  Further, without using Xbar ± 6σ = about 423,203 shown in FIG. 21, Xbar ± 6σ = about 419,200 shown in FIG. 20 is changed to the maximum value Z and the minimum value Y of the set range (Y to Z). May be set as Alternatively, without using Xbar ± 6σ = about 419,200 shown in FIG. 20, Xbar ± 6σ = about 423,203 shown in FIG. 21 is changed to the maximum value Z and the minimum value Y of the setting range (Y to Z). May be set as

  In the seventh embodiment, when the number of hard random numbers acquired by the random number acquisition unit 51 reaches a predetermined number, the abnormality determination unit 53 determines the hardware that has been determined as a specific value by the random number determination unit 52 for the predetermined number. It is determined whether the ratio of the number of random numbers is within a setting range determined based on the ratio of the number of specific values to the total number of hard random numbers that can be generated by the random number generation means 40.

  As shown in FIG. 22, in this hard random number abnormality detection process, D represents the hard random number obtained by the random number obtaining unit 51, and the hard random number obtained by the random number judging unit 52 is the specific value of the hard random number obtained. This indicates the specific value determination number ratio (B / A) of the specific value determination number A, and is initially set to 0 when the power is turned on.

  In this hard random number abnormality detection process, B / A is calculated after S64; No or S65, and the B / A is set to the specific value determination number ratio D. still. This D is stored in a predetermined storage unit. Thereafter, when S66; Yes, instead of S67 of the first embodiment, DY (for example, 1/640 (≈205 / 65536 × 1/2)) ≦ D ≦ DZ (for example, 1/160 (≈205 / 65536) X2)) is determined (S232). If S232; No, the process proceeds to S68, and then proceeds to S233. If S232; Yes, the process proceeds to S233. S233 is an alternative to S70 of the first embodiment, and F1, A, B, and D are reset to 0, and then the process returns. According to the technique of the seventh embodiment, the same operations and effects as the first embodiment are achieved.

In the first to seventh embodiments, the following changes can be made.
(1) The jackpot symbol random number is composed of a hard random number, and the jackpot symbol random number is detected as to whether or not there is an abnormality in the hard random number like the aforementioned jackpot random number. The jackpot symbol random number is an important one that determines the special symbol at the time of the jackpot (that is, the game state to be transferred after the jackpot game state is finished), and by detecting the presence / absence of this jackpot symbol random number, It is possible to prevent the player or the game hall from being disadvantaged due to the abnormality.

(2) The random number acquisition cycle by the random number acquisition unit 51 is regularly set every 4 ms in the above embodiment, but may be configured to be acquired every random minute time. That is, it is possible to verify whether or not the performance including the original hard random number generation circuit of the pachinko gaming machine 1 is maintained by obtaining hard random numbers that are more practical.

(3) The above X, Y, Z and the like can be changed as appropriate in consideration of the performance of the pachinko gaming machine 1 and to change the accuracy of abnormality determination and the like.
(4) The random number acquisition unit 51 uses only the hard random number acquired by the random number acquisition unit 41 from the random number generation unit 40 as being acquired from the random number abnormality detection unit 50. That is, it takes a long time to determine the abnormality, but it is possible to verify whether the performance including the original hard random number generation circuit of the pachinko gaming machine 1 is maintained by using the practical value.

(5) The hard random number acquisition process is performed in order to determine the hard random number abnormality immediately after the power is turned on, but the hard random number acquisition unit 51 stops acquiring the hard random number thereafter. After that, the jackpot probability by practice is monitored (calculated), and when the practice jackpot probability is out of the assumed probability range, it is determined that a certain condition is satisfied, and acquisition of a hard random number by the random number obtaining unit 51 is started, You may make it perform abnormality determination of a hard random number.

(6) In addition, various modifications can be added without departing from the spirit of the present invention. The present invention can be applied to various pachinko gaming machines, slot machines other than pachinko gaming machines, and other various gaming machines.
