Description

  The present invention relates to a technique for detecting abnormal hard random numbers in gaming machines.

  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.

  When the number of hard random numbers acquired by the random number acquisition unit 51 reaches a predetermined number based on the random number information received from the main control device 21, the abnormality determination unit 54 determines the random number determination unit among the predetermined number of hard random numbers. It is determined whether or not the number of hard random numbers determined as the specific value by 52 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.

  In other words, when the number of hard random numbers acquired by the random number acquisition unit 51 reaches a predetermined number based on the random number information received from the main control device 21, the abnormality determination unit 54 includes the predetermined number of hard random numbers. A setting range in which the ratio of the number of hard random numbers determined to be a specific value by the random number determination unit 52 to the predetermined number is 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 It is also determined whether the ratio is within the range.

  Specifically, every time the abnormality determination unit 54 receives an affirmative determination command or a negative determination command from the random number information output unit 53, the random number acquisition number of the big hit random number (hard random number) acquired by the random number acquisition unit 51 from the command (Total number of reception of affirmative determination command and negative determination command) and a specific value determination number of the big hit random number determined as a specific value by the random number determination unit 52 (total number of reception of the positive determination command) are calculated.

  When the number of jackpot random numbers acquired by the random number acquisition unit 51 reaches 100,000, which is equal to or greater than the total number of jackpot random numbers (65536) that can be generated by the random number generating means 40, the random number determination unit 52 identifies the jackpot random numbers. The number of jackpot random numbers determined to be a value was 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 generator 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 55 stores the random number acquisition number of the hard random number acquired by the random number acquisition unit 51, and the second storage unit 56 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 54 performs said determination based on the information of the 1st, 2nd memory | storage parts 55 and 56. FIG.

  Next, in the random number abnormality detection system S of the pachinko gaming machine 1, processing executed by the main control device 21 will be described based on a flowchart, and thereafter processing executed by the hall computer 59 will be described based on the flowchart.

  First, as shown in FIG. 5, in the timer interrupt process for every minute time (4 ms) in the game control board 22, random number update process (S1), switch process (S2), symbol process (S3), electric accessory process (S4), prize ball processing (S5), random number detection processing (S6), and output processing (S7) are sequentially executed, and the process returns.

  As shown in FIG. 6, in the start port SW process of S2, the first hold port SW10a is on (S11; Yes), and the first hold number U1 is less than 4 (S12; Yes), the first hold The number U1 is added to U1 + 1 (S13), the first random number (big hit random number, big hit symbol random number, etc.) is acquired and stored (S14), and the first pending number increase command is set (S15). After S11; No or S12; No or S15, the process proceeds to S16.

  Next, when the second start port SW11d is on (S16; Yes), when the second hold number U2 is less than 4 (S17; Yes), the second hold number U2 is added to U2 + 1 (S18). Two random numbers (big hit random number, big hit symbol random number, etc.) are acquired and stored (S19), and the second pending number increase command is set (S20). S16; No or S17; After No or S20, the process returns. Note that the commands set in S15 and S20 and the commands set in other steps are transmitted to the effect control board 27 by the output process of S7.

  As shown in FIG. 7, in the special symbol process of S3, when the winning game flag is not ON (that is, during big hit game or small hit game) (S31; No), both the first and second special symbols are changed. If not (S32; No), the process proceeds to S33. If S31; Yes, the process returns. If S32; Yes, the process proceeds to S42.

  Next, when the second hold number U2 is 1 or more (S33; Yes), the second hold number U2 is subtracted from U2-1 (S34), and when the second hold number U2 is 0 (S33; No), When the first hold number U1 is 1 or more (S35; Yes), the first hold number U1 is subtracted from U1-1 (S36). After S34 or S36, the customer waiting flag is turned off (S37), the special symbol determination process (S38) is executed, and then the variation pattern selection process (S39) is executed. S35: If No, the customer waiting setting process (S46) is executed and the process returns.

  As shown in FIG. 8, in the special symbol determination process of S38, first, the big hit random number determination process (S51) is executed. 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, four 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). Next, it is determined whether or not the variation time set in S39 has passed (S42). If S42;

  On the other hand, if S42: Yes, the first or second special symbol is suspended (S43), and the special symbol set in S38 is displayed on the first or second 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 random number detection process in S6 will be described in detail with reference to FIGS. F1 is a random number detection execution flag, F2 is a random number detection end flag, F3 is a random number detection interruption flag, A is a random number acquisition number, T is a random number detection interruption timer, and F1, F2, F3, A, and T are power supplies It shall be initialized to 0 at the time of input.

  As shown in FIG. 10, in this random number detection process, first, it is determined whether or not the random number 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 jackpot specific value in the normal gaming state and the short-time gaming state) (S64).

  In the case of S64; Yes, an affirmative determination command is set (S65), and in the case of S64; No, a negative determination command is set (S66). After S65 or S66, it is determined whether or not A = X (100,000 pieces) (S67). S67: If Yes, the random number detection end flag F2 is set to 1 (S68), the random number detection end command is set (S69), F1 and A are both reset to 0 (S70), and the process returns. S67; If No, return.

  The commands set in S65, S66, and S69 are output to the hall computer 59 instead of the sub-control device 25 in the output process of S7. On the other hand, in the case of S61; No, a random number detection start determination process (S71) is executed.

  As shown in FIG. 11, in the random number detection start determination process of S71, it is first determined whether or not the random number detection interruption flag F3 is 1 (S81). S81: If No, it is determined whether or not the random number detection end flag F2 is 1 (S82). S82: If Yes, F2 is reset to 0 (S83), the random number detection interruption flag F3 is set to 1 (S84), then the random number 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 random number detection interruption timer T is reset to 0 (S87), and the random number detection interruption flag F3 is reset to 0 (S88). S86; If No, return. After S82; No or S88, a random number detection start command is set (S89), the random number detection execution flag F1 is set to 1 (S90), and then a specific value setting process (S91) is executed. The command set in S89 is output not to the sub-control device 25 but to the hall computer 59.

  In the specific value setting process of S91, a process of setting a big hit specific value as the specific value is performed. In this embodiment, 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, so S91 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 S90, the random number 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 is Yes, S61 to S67 are repeatedly executed from the start of S6 every 4 ms until the random number acquisition number A reaches 100,000, and the random number detection execution flag F1 is set to 1. 400 seconds later, when the random number acquisition number A reaches 100,000, S67; Yes, the random number detection end flag F2 is set to 1 in S68, and the random number detection execution flag F1 is set to 0 in S70. Reset to.

  Therefore, from the start of the next S6, S61; No → S71 → S81; No → S82; Yes →..., The random number detection end flag F2 is reset to 0 in S83, and the random number detection interruption flag F3 is set in S84. In S85, the random number detection interruption timer T is started.

  Therefore, from the start of the next S6, S61; No → S71 → S81; Yes →..., And the processing for obtaining and determining the hard random number is suspended until the random number detection interruption timer T reaches 1 hour. No → S71 → S81; Yes → S86; No is repeatedly executed. Then, when the random number detection interruption timer T reaches 1 hour, the random number detection execution flag F1 is set to 1 in S90. Therefore, from the start of the next S6, S61; Yes → S62 →. Then, processing for obtaining and determining a hard random number is executed.

  Note that, during the execution of the random number detection process shown in FIG. 10, if a game ball wins the start opening 10 or 11a, a hard random number acquisition determination process is performed in this actual game. The random number acquisition determination process and the random number 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) in the hall computer 59, it is first determined whether or not a command is received from the pachinko gaming machine 1 (S101), S101; If YES, return to step S101; if YES, determine whether the command is a random number detection start command (S102). In the case of S102; Yes, the pachinko gaming machine 1 that has output the random number detection start command received in S101 is specified, and random number abnormality determination processing (S104) is executed for the pachinko gaming machine 1.

  The random number abnormality determination processing in S104 is as shown in FIG. Note that B represents the specific value determination number, C represents the random number acquisition number, and B and C are initially set to 0 when the power is turned on.

  As shown in FIG. 13, in this random number abnormality determination process, first, it is determined whether or not a positive determination command is received from the main control device 21 (S111). In the case of S111; Yes, the specific value determination number B is added to B + 1 (S112), and then the random number acquisition number C is added to C + 1 (S113). On the other hand, in the case of S111; No, it is determined whether or not a negative determination command is received from the main control device 21 (S114). S114: In the case of Yes, only the random number acquisition number C is added to C + 1 (S113).

  After S113 or S114; No, it is determined whether or not an abnormality detection end command has been received from the main control device 21 (S115). In the case of S115; No, the process returns. In the case of S115; Yes, it is determined whether or not C = X (100,000 pieces) (S116). In the case of S116; Yes, it is determined whether or not Y (156) ≦ B ≦ Z (626) (S117), and in the case of S117; No, it is determined as abnormal (S138). S117: Yes or after S118, both B and C are reset to 0 (S119), and the process returns.

  On the other hand, in the case of S116; No, error processing (S120) is executed and the process returns. S116: The error processing in the case of No is that the number of hard random numbers acquired does not match between the gaming machine 1 side and the hall computer 59 side, that is, the A calculated by the main controller 21 and the hall computer 59 calculated This is because C does not match, and therefore, it is prevented that abnormality determination is not normally performed as error processing. In the error process of S120, the error may be notified. Note that S115 and S120 may be omitted. That is, after S113 or S114; No, it is determined whether or not C = X (100,000) (S116). If S116; Yes, the process proceeds to S117, and if S116; No, the process returns.

  As shown in FIG. 12, after the random number abnormality determination process in S104, it is determined whether or not an abnormality is determined, that is, whether or not S117 in FIG. 13; No (S105). If S105; S105: If Yes, the random number abnormality notification process (S106) is executed, and the process returns. In this random number abnormality notification process, for example, on the display attached to the hall computer 59, information indicating the pachinko gaming machine 1 having an abnormality in the hard random number, such as “XX series: hard random number abnormality”, is associated with the information. Information indicating abnormal hard random numbers is displayed.

  In the case of S102; No, the game management process (S107) is executed and the process returns. In addition to the command for detecting abnormal hard random numbers, the hall computer 59 receives a symbol change command and a jackpot command from each pachinko machine 1, and based on the game management process in S107, these pachinko machines Game information such as the number of symbol changes and the number of jackpots of the gaming machine 1 is aggregated. The hall computer 59 has the ability to execute random number abnormality determination processing in parallel for a plurality of pachinko gaming machines 1.

According to this pachinko gaming machine 1 and its random number abnormality detection system S, the following effects are obtained.
The main control device 21 of the pachinko gaming machine 1 is provided with a random number detection means 50 for detecting an abnormality of the hard random number. In the random number detection means 50, the random number acquisition unit 51 sequentially receives a plurality of hard random numbers from the random number generation means 40. Then, the random number information output unit 53 outputs the random number information regarding the plurality of hard random numbers acquired by the random number acquisition unit 51 to the hall computer 59 connected to the main control device 21.

  In the hall computer 59, when the abnormality determination unit 54 reaches the predetermined number of hard random numbers acquired by the random number acquisition unit 51 based on the random number information received from the main control device 21 of the pachinko gaming machine 1, A setting in which the number of hard random numbers determined to be a predetermined specific value among the predetermined number of hard random numbers is 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 generating means 40 Judge whether the number is within the range.

  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 detection unit 50 includes a random number determination unit 52 that determines whether or not each hard random number acquired by the random number acquisition unit 51 is a specific value, and the random number information output unit 53 determines the hard random number by the random number determination unit 52. Since the random number information including the information is output, in the pachinko gaming machine 1, it is reliably determined whether or not each hard random number is a specific value, and the processing load for detecting the random number abnormality in the hall computer 59 is reduced. Therefore, the hall computer 59 can reliably execute the random number abnormality determination process for the plurality of pachinko gaming machines 1 in parallel.

  The random number information output unit 53 outputs positive determination information as determination information when the positive determination is performed by the random number determination unit 52, and outputs negative determination information when a negative determination is made. It is possible to accurately obtain the number of hard random numbers acquired by the random number acquisition unit 51 and the number of hard random numbers determined to be the specific value by the random number determination unit 52 and reliably execute the determination by the abnormality determination unit 54 it can.

  The hall computer 59 includes a first storage unit 55 that stores the number of hard random numbers acquired by the random number acquisition unit 51 and a second storage unit 56 that stores the number of hard random numbers determined by the random number determination unit 52 as a specific value. Since the abnormality determination unit 54 determines based on the information in the first and second storage units 55 and 56, when the number of hard random numbers acquired by the random number acquisition unit 51 reaches a predetermined number, 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 55 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 55 and 56 is reset. After that, since the acquisition of the hard random number by the random number acquisition unit 51 is started when the certain condition is satisfied, the determination of the certain condition is satisfied instead of continuously executing the acquisition determination of the hard random number and the subsequent abnormality determination. It can be executed intermittently every time to check periodically whether there is an abnormality in the hard random number.

  When the abnormality determination unit 54 makes a negative determination, the hall computer 59 can identify and notify the pachinko gaming machine 1 having an abnormality in the hard random number. By preventing the pachinko gaming machine 1 itself having an abnormality in the hard random number from being notified by a notification device such as the image display 16 or the like, it is possible to eliminate a factor that causes the player to feel uneasy. However, information indicating abnormality determination is fed back from the hall computer 59 to the sub-control device 25 of the pachinko gaming machine 1 having an abnormality in the hard random number, and the sub-control device 25 controls the notification device such as the image display 16. Then, the abnormality of the hard random number may be notified.

  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 54 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 determination process, D indicates the number of abnormality determinations, and is initially set to 0 when the power is turned on. In this random number abnormality determination process, in the case of S117; No, that is, when the specific value determination number B is not within the set range, the abnormality determination number D is added to D + 1 (S201), and then D is preset. It is determined whether or not it is a plurality of times α (for example, α = 3 times) (S202). If S202; No, the process proceeds to S119. If S202; Yes, D is reset to 0 (S203), and an abnormality is determined (S118).

  That is, when the number of negative determinations made by the abnormality determination unit 54 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 notification process (S106) is executed. This makes it possible to more reliably detect and notify whether there is an abnormality in the hard random number.

  However, the abnormality determination number D may be the number of times that the abnormality determination unit 54 has made a negative determination continuously. That is, if the determination is affirmative in the next determination in which the abnormality determination number D is added, D 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 D is added, the main control device 21 may immediately switch to S61; Yes from the start of S6 thereafter, and 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 determination process of FIG. 10, S61, S68, and S71 (FIG. 11) are omitted, and in S70, the process of A ← 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 random number detection process, after S61; Yes, whether or not the first or second starter SW 10a or 11c is on (that is, whether S11 (S12) or S16 (S17) is Yes) No) 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 S91, N indicates the specific value determination number, 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 game control board 22 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
