JP 2005-270217 A JP 2002-301194 A

  In recent gaming machines, as in Patent Document 2, a special state other than a so-called AT (assist time) or RT (replay time) state is generated, and the payout rate in that period is improved. A gaming machine is provided. When base abnormality detection is performed for such a gaming machine as a management target, if a state signal corresponding to the state is output from the gaming machine as in Patent Document 1, it is possible to detect the base abnormality according to the state. In fact, gaming machines that do not output status signals occupy a large number of markets. For this reason, when an AT or RT state or the like occurs in a gaming machine, there is a problem that base abnormality detection occurs frequently even though the gaming machine is not cheating. In this case, each time a base abnormality detection occurs, it was dealt with by checking the state of the gaming machine by a staff member or setting so that the base abnormality detection itself was not performed. The situation is extremely inconvenient.

  The present invention has been made in view of the above circumstances, and the purpose thereof is that the winning rate of the winning combination varies depending on the gaming state, and a state signal that can specify the gaming state is not output from the gaming machine side. An object of the present invention is to provide a management apparatus for a game arcade that can detect an abnormality in a gaming machine with high accuracy.

  The present invention is a gaming machine that identifies a winning combination for each game and provides a game medium to a player as a privilege according to the winning combination, and is a specified combination that is at least one of a plurality of provided roles. It is a management device for a gaming hall that manages gaming machines whose winning rate varies depending on the gaming state, and is a gaming signal output from the gaming machine side that can specify that a game has been played A receiving means for receiving a game signal and a payout signal that can specify a payout number that is the number of game media given to the player corresponding to the privilege, and an allowable payout number that is allowable in a predetermined period. The allowance information storage means for storing the payout allowance information corresponding to the corresponding information, and the payout number for each predetermined period based on the game signal received by the receiving means, and the determined payout number that is the specified payout number Corresponding game information and previous An abnormality detection means for detecting an abnormality by comparing with the payout allowance information stored in the allowance information storage means, a payout number storage means for storing the payout number corresponding to the specific combination in advance, and a game signal received by the receiving means Based on the number-of-payout specifying means for specifying the number of payouts for each game, the number of payouts corresponding to the specific role stored in the payout-number storage means, and the number of payouts for each game specified by the payout-number specifying means A small combination determination unit that determines whether or not a specific combination is won for each game, and an exclusion unit that excludes the number of payouts in the game determined to have won a specific combination by the small combination determination unit from the determined determination amount The abnormality detecting means corresponds to the number of payouts based on the number of payouts that is the number of payouts that is the number of payouts excluded from the number of payouts in the game determined to have won the specified combination from the number of payouts determined by the excluding means. Shi And performs abnormality detection for game information (claim 1).

  In the above-described configuration, a setting operation for payout setting information, which is payout allowance information corresponding to all winnings including a specific combination, is accepted, and the accepted payout setting information is stored in the allowance information storage unit as the payout allowance information. Exclusion allowance information that is allowance information corresponding to the exclusion allowance payout number excluding the payout number corresponding to the winning of a specific role that is expected to win when the game is performed for the predetermined period from the allowable payout number And an allowance value specifying means for specifying, wherein the abnormality detecting means is an excluded payout number that is a payout number excluding the payout number in the game determined to have won the specific combination from the determined payout number by the excluding means. When the abnormality detection is performed on the game information corresponding to the game information, the exclusion value allowance information specified by the tolerance value specifying means is compared with the game information corresponding to the number of exclusion payments. May also be detected (claim 2).

  Further, the gaming machine to be managed is configured to be able to identify the winning combination in one game, and the payout amount storage means stores the corresponding payout numbers for a plurality of combinations in the gaming machine. The combination determining means does not correspond to any of the number of payouts corresponding to the plurality of combinations stored in the payout number storage means, and the number of payouts per game specified by the payout number specifying means When the number is more than the number, it is determined that a plurality of roles including a specific combination have been won, and the exclusion means has won a plurality of combinations including a specific combination by the small role determination unit. All or part of the number of payouts in the game determined to be may be excluded from the determined number of payouts (claim 3).

  In addition, the gaming machine to be managed has a plurality of specific combinations, and the winning rate of the first specific combination that is one of the specific combinations and the second specific combination that is also one of the specific combinations is the winning percentage. The game state that can be changed in an overlapping manner can be generated, and the number of game media to be given to the player as a corresponding privilege is configured to be different between the first specific combination and the second specific combination, The number of payouts corresponding to the first specific combination and the second specific combination is stored separately, and the small combination determination means determines the presence / absence of winning for the first specific combination and the second specific combination for each game. The allowance information storage means stores winning allowance information that is allowance information corresponding to an allowable winning rate that is a ratio of the number of wins of the second specific winning combination with respect to the first specific winning combination that can be allowed in the predetermined period, and detects the abnormality. The means is for the first specific combination in the predetermined period. A game information corresponding to the winning number percentage of a particular role, may be used to detect the abnormality by the permission information storage means collates the winning tolerance information stored (claim 4).

  In addition, the abnormality detecting unit is configured to detect the exclusion allowable information and the excluded payout specified by the allowable value specifying unit on condition that an abnormality is detected by comparing the game information corresponding to the determined payout number with the payout allowable information. You may make it perform abnormality detection by collating with the game information corresponding to a number (Claim 5).

  According to the invention of claim 1, even if the winning rate of the specific combination varies according to the gaming state and a state signal that can specify that the gaming state is not output from the gaming machine side, If it is determined that the game has been won, an abnormality is detected for the game information corresponding to the number of payouts based on the number of payouts excluded from the determined number of payouts for each predetermined period. Accordingly, it is possible to exclude fluctuations with respect to the number of payouts by a specific combination whose winning rate varies. Thereby, even when the winning rate of the winning combination fluctuates according to the gaming state, it is possible to accurately detect an abnormality without performing a false detection.

  According to the invention of claim 2, the excluded payout allowance information corresponding to the excluded allowable payout number excluding the payout number corresponding to the winning of the specific role expected to win when a game is performed for a predetermined period from the allowable payout number. Since the allowance value specifying means identifies the payout allowance information, it is approximated to the number of excluded payouts of other game models that are not provided with a specific role, so that it is the same as other game models that are not provided with a specific role for payout allowance information. (For example, the same for all models) can be set (collectively), and the appropriate exclusion payout allowance information can be specified simply by setting the presence / absence of a specific combination and the winning rate. . Also, payout allowance information can be set while comparing with other game machines. In particular, if only RT is a game model provided as a special state, the specific role is only the replay role, and generally the winning rate of the replay role is 1 / 7.3, and the corresponding safe is a predetermined value such as 3. Therefore, the number of winnings and the specific combination payout in the predetermined period are the same. Therefore, if the value is set as a default value, the exclusion allowance information can be set only by setting the payout permission information and setting the specific combination as the replay combination, and the setting operation is further facilitated.

  According to the invention of claim 3, even if the specific combination wins another winning combination with respect to a gaming machine in which the specific combination wins another winning combination, Since all or a part of the payout amount due to winning such a prize is excluded from the determined payout amount, it is possible to accurately detect an abnormality in consideration of a player's technical intervention or the like.

  According to the invention of claim 4, when the winning rate of the first specific combination and the second specific combination fluctuate and overlap, the ratio of the number of winning of the second specific combination to the first specific combination in a predetermined period Since the corresponding game information does not fluctuate greatly, by comparing the game information corresponding to the ratio of the number of winning of the second specific combination with respect to the first specific combination in a predetermined period, the winning allowance information stored in the allowable information storage means, Even if a fraud targeting a specific combination excluded from the detection target is performed, fraud can be detected.

  According to the fifth aspect of the present invention, if there is no so-called base abnormality, the abnormality detection excluding the specific role is not performed, so that the processing load of the management apparatus can be reduced while improving the abnormality detection accuracy.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows the overall configuration of the system. A relay device 1 is installed in the amusement island. The relay device 1 is connected to the management device 3 and other relay devices 1 via the LAN 2 and can transmit and receive various types of information. The relay device 1 is also connected to a gaming machine 4 and a call lamp 5 provided corresponding to the gaming machine 4, a lending device 6 and the like, and performs relay processing (information transmission / reception) with the management device 3. ing.

  FIG. 2 schematically shows a front appearance of a slot machine which is a gaming machine. A display window 7 is provided in front of the slot machine 4, and the player can visually recognize the symbols of the left reel 8a, the middle reel 8b, and the right reel 8c provided therein through the display window 7. In this case, the symbols are drawn on the circumferential surfaces of the left reel 8a, the middle reel 8b, and the right reel 8c. When the reels 8a to 8c are stopped, they correspond to the upper, middle, and lower stages of the display window 7. The symbol is displayed. The display window 7 is provided with a total of five winning lines (three horizontal lines corresponding to the upper, middle and lower stages and two diagonally arranged) (shown by broken lines in FIG. 2). An active line display section 9 for displaying the activated pay line is provided on the side of the, and a corresponding win is generated when the winning symbols are aligned on any of the pay lines. .

  Above the display window 7, a liquid crystal display unit 10 and a speaker 11 for displaying various information such as a payout progress state of medals in a bonus are provided. Below the display window 7, there are provided a MAXBET button 12 for betting credit medals, a settlement button 13 for settlement of credit medals, and a medal insertion slot 14 for placing medals, below which a start lever 15 is provided. A left stop button 16, a middle stop button 17, and a right stop button 18 are provided. On the right side of the display window 7, a payout number display unit 19 for displaying the number of payout medals and a credit number display unit 20 for displaying the number of credit medals are provided. Furthermore, a tray 21 is provided at the lowermost front part of the slot machine 4, and a decorative lamp part 22 is provided at the uppermost front part of the slot machine 4.

  The slot machine 4 performs an internal lottery when a series of game start operations are performed, that is, when the player operates the start lever 15 with a medal inserted into the medal slot 14 or a bet with a credit medal through the MAXBET button 12. Each reel 8a-8c is started (rotation operation is started).

  In the slot machine 4, after starting the reels 8a to 8c, the reels 8a to 8c are stopped according to the operation of the stop buttons 16 to 18 to finish one game. If the result of the internal lottery is winning, an internal winning flag corresponding to the internal winning combination won by the internal lottery (big bonus internal winning flag, regular bonus internal winning flag, small bonus internal winning flag, replay internal winning flag ) Is turned on (established), and based on the internal winning flag, stop control including so-called slip control (retraction control) (respective reels 8a to 8c are stopped with a winning symbol or a lost symbol depending on the type of the internal winning flag). Control), and the number of medals corresponding to the winning symbol is discharged to the tray 21. The pull-in control is a control capable of drawing and stopping up to four symbols on the winning line from when the operation of the stop buttons 16 to 18 is detected.

The slot machine 4 can set a bonus winning probability in a plurality of stages by a specific employee operating the setting means with the front door opened.
FIG. 3 shows an example of the bonus probability of the model A. As the “set value”, 1 to 6 are set. The higher the setting, the higher the bonus winning rate and the payout rate. Note that the small role probability is common to all set values.

FIG. 4 is a diagram illustrating the probability (common to all set values) of the winning combination (other than the bonus) of the model A. Each item of “number of payouts”, “internal winning rate”, and “AT combination” is set in the probability of winning combination corresponding to “name”. “Internal winning rate” is set to “normal (non-bonus or special gaming state)” and “RT (replay time).” For small role 1, the number of payouts is 4, and the internal winning rate Is set to 1/30. For the small roles 2 to 4, the number of payouts is set to 6 and the internal winning probability is set to 1/9, so the symbols are arranged so that they cannot be aimed at the same time. AT role (corresponding to a specific role) Small number 5 is set to 15 payouts and internal winning rate is set to 1/20. It is also set as a duplicate combination (one of the symbols constituting the duplicate combination is 2 to 4 small combinations), in which case the number of payouts is set to 15 and the internal winning rate is set to 1/100. (Corresponding to a specific role), the number of payouts is 3 (in the case of 3), the internal winning rate in normal time is 1 / 7.3, RT time .RT generating role that is set to /1.9, the payout is 0 Like the internal winning rate at the normal time is set to 1/300.
As can be seen from FIG. 4, the internal winning rate differs between the normal time and the RT time only in the replay combination. In addition, 6 out of 15 payouts of duplicated combinations are the number of payouts by the AT combination (small combination 2 to 4).

Next, the basic operation of the slot machine 4 will be described.
(1) The internal lottery is executed in response to the start of the game, and the pull-in control is executed on the reels 8a to 8c so that the internal winning combination wins in accordance with the operation of the stop buttons 16 to 18.
(2) When the internal winning is performed for the double roles such as the small roles 2 and 5, etc., if the stop buttons 16 to 18 are operated at a timing at which both of the double roles can be drawn, the pull-in control is performed so that both of the double roles win. . Even if it is not possible to perform the pull-in control of both of the duplicated roles, the pull-in control is performed only for the small role that can be pulled-in if one of the duplicated roles can be controlled.
(3) When an RT winning combination is won, an RT state (a gaming state in which the internal winning rate of the replay combination is high: equivalent to a special state) is entered.
(4) B. B (Big Bonus), R.B. When the B (regular bonus) symbols are available, each bonus state is entered.
(5) B. B, R.M. During B, the winning rate of the small role increases, and when the predetermined payout number is reached, the game ends.
(6) B. After the completion of B, in the AT state (the small role in which the player has been played is informed by the liquid crystal display unit 10 or the like of the small role that has been internally won among the small roles 2 to 4 which are AT roles) A game state in which a winning rate is increased by performing a so-called push on a symbol corresponding to a combination, including a case where a winning combination is won: equivalent to a special state) and an ART state in which the RT state is combined.
(7) The number of continuation games (0, 100, 500, 1000 games) in the RT state and the ART state is selected (lottery with a predetermined probability (1/4 each)) every time the state occurs.
(8) The RT state and the ART state are terminated when the number of continuous games is exhausted or a bonus is generated.

The slot machine 4 outputs the following signal.
(1) Out signal (One pulse output for one medal used (however, the output timing is lever operation: equivalent to game signal))
(2) Safe signal (One pulse output for one payout (Note that the number of medals bet on the game (3) is pulse output when winning a replay role)
(3) B. B signal (level signal output during BB)
(4) R.M. B signal (level signal output during RB)
As a game signal, a reel signal output for each game other than the out signal may be adopted.

  The management apparatus 3 includes a CPU (corresponding to an abnormality detection means, a payout number specifying means, a small part determination means, an exclusion means, a setting means), a storage unit such as an HDD, ROM, RAM (allowable information storage means, payout number storage means). Equivalent), I / O (corresponding to receiving means), keyboard (corresponding to setting means), and the like.

The management device 3 stores the small role setting for each winning model in units of game models.
FIG. 5 is a diagram showing the small combination setting of the model A. In the small role setting, each item of “number of payouts”, “specific role”, “winning rate”, “duplicate role” is set corresponding to “name”, and the meaning of each item is as follows: It is.
Number of payouts: Number of game media to be paid out in a winning game with the number of payouts corresponding to the small role Specified role: Specified role (Special bonus (RT, AT) when the winning rate of the small role is high except in the bonus state) The small combination with the highest rate is set as the specific combination 1 (corresponding to the standard specific combination) with the highest winning ratio.
Winning rate: Winning rate for one game in the normal state (internal winning rate other than AT role, winning rate assumed when AT role is not in AT state)
Duplicate role: “Yes” if it can occur as a duplicate role, “No” if it cannot occur
In the example illustrated in FIG. 5, a small combination 1, a small combination 2, a small combination 5, and a replay combination are set as the “name”. As for the small roles 2 to 4, the number of payouts is the same for 6 sheets, and it is difficult to identify which small role from the safe number. Therefore, the name of the small role 2 is a general name of the small roles 2 to 4. It becomes. Specifically, the number of payouts for the small combination 1 is set to 4 and “nothing” is set as the duplicate combination. The number of payouts of the small combination 2 is set to 6, the specific combination 2 as the specific combination, 1/9 as the winning rate, and “present” as the duplicate combination. Nine pieces are set as the number of payouts of the small combination 5, and “Yes” is set as the duplicate combination. The number of payouts for the replay combination is 3, the specific combination 1 is specified as the specific combination, the winning rate is 1 / 7.3, and “nothing” is set as the duplicate combination.

  Here, the specific combination will be described in detail. The slot machine 4 in the present embodiment is provided with a plurality of special states of the RT state and the ART state, but does not have a special state of the AT state alone. That is, the replay combination has a high winning rate in any of the special states (RT, ART), but the AT combination has a high winning rate only when it is in the ART state. In other words, because of the specs, the replay role has a longer period of time during which the winning rate is higher than the AT role, so the replay role has the highest priority in the specific role (the period in which the winning rate is higher). Expected value is the highest among specific roles). Therefore, the replay combination is set as the specified combination 1, and the AT combination having the next highest expected value is set as the specified combination 2.

  Next, the winning rate of the AT combination (name “small combination 2”) will be described in detail. Since the pull-in control is for 4 symbols as described above, the pull-in range of each symbol is 7 symbols (3 symbols at the time of operating the stop button + 4 symbols for the pull-in control). Here, in the present embodiment, one symbol corresponding to each AT combination (small combinations 2 to 4) is arranged on the reel 8a every 6 symbols, and a small combination corresponding to the case where the symbol stops is awarded. It is a role. Therefore, since the drawing range of each symbol corresponding to the AT combination is not overlapped, there is no effect to hold in the normal time when the internal winning combination cannot be grasped. In addition, since 21 symbols are drawn on each of the reels 8a to 8c, if the player operates the stop buttons 16 to 18 without having a pressing effect, the probability that the player can operate within the drawing range of each symbol is 7 symbols of 21 symbols, that is, 1/3. Therefore, the winning rate of each AT role in the normal state is 1/27, which is obtained by multiplying the internal winning probability (1/9) by the probability (1/3) that can be operated within the drawing range of the corresponding symbol. The winning rate is also 1/27. Therefore, the probability that any of the AT roles will win in normal times (the winning rate of the AT role in normal times) is set to 1/9 obtained by multiplying each winning rate (1/27) by the number of types of AT roles (3). become.

  On the other hand, since the internal winning combination is notified to the player at the time of AT, the probability that it can be operated within the pull-in range can be regarded as 1/1 (almost 100% for the skilled player can be expected). it can. Therefore, the AT winning rate for AT roles is multiplied by the probability of being able to operate within the pull-in range (1/1) by the internal winning probability (1/9) of each AT role, and further by the number of types of AT roles (3). 1/3 is set.

In addition, the pachinko hall sets an allowable value setting for the management apparatus 3 for each game model.
FIG. 6 shows an example of the allowable value setting. For the allowable value setting, “determination out”, “abnormal upper limit value”, “exclusion upper limit value”, “specific role 1”, “specific role 2”, “special role payout” corresponding to “model name”, Each item of “standard small percentage upper limit value” is set, and the meaning of each item is as follows.
Judgment out: The number of outs for specifying the period during which base abnormality detection is performed, and abnormality detection is performed each time the judgment out reaches a set value. Note that the base abnormality detection is for game states other than bonuses.
Upper limit of abnormality: Upper limit of judgment safe (equivalent to “number of payouts per predetermined period”) that can be allowed when a base abnormality is detected (equivalent to the number of payouts and payout setting information). When the upper limit value is abnormal), the process shifts to abnormality detection based on the exclusion upper limit value (when a gaming machine having no specific role deviates, the abnormality is immediately notified (so-called base abnormality detection)).

Exclusion upper limit value: The value obtained by subtracting (excluding) the specified role payout from the abnormal upper limit value. If the exclusion safe deviates from the allowable value (the upper limit value (corresponding to the allowable payout number or the allowable exemption allowance number)) or more ) Shifts to anomaly detection based on the standard small percentage upper limit for gaming machines having a plurality of specific combinations. In addition, an abnormality is detected immediately when a gaming machine having no specific role deviates. In addition to the calculation based on other set values, numerical values may be directly operated and input.
Specific combination 1 (2): The presence / absence of a specific combination. If there is a specific combination 1 (2) in FIG. 5, the winning rate is set.
Specific combination payout: The number of specified combination payouts when a specified combination is won according to the set winning rate after playing the game for the judgment out. In FIG. 6, it is assumed that three outs are used in one game, and the determination is made by “determination out ÷ 3 × special combination winning rate × number of specific combination payouts”. In addition, when there are a plurality of specific combinations such as model A, the total value is obtained. In addition to the calculation based on other set values, numerical values may be directly operated and input.
Reference small percentage upper limit value: An upper limit value (equivalent to winning allowance information) of a standard minor percentage that is allowed when a base abnormality is detected.
In the example shown in FIG. 6, the model A “determination out” is 1000, the “abnormal upper limit value” is 800, the “exclusion upper limit value” is 441 (= 800-359), and the “specific combination 1” is 1 / 7.3. 1/9 is set as the “special combination 2”, and 359 (= 1000 ÷ 3 × (1 / 7.3 × 3 + 1000 ÷ 3 × (1/9) × 6) is set as the “special combination payout”.

In the management apparatus 3, an abnormality determination storage area is set for each model.
FIG. 7 shows an example of the storage area for abnormality determination of model A. In the abnormality determination storage area, “determination out”, “determination safe”, “small role safe”, “specific combination 1 winning number”, “specific combination 2 winning number”, “corresponding to“ gaming machine ID ”, Each item of “Exclusion Safe” and “Standard Minor Ratio” is set, and the meaning of each item is as follows.
Number of specified combination 1 (2) winning: The number of winning of specified combination 1 (2) that won in the determination period. If the specific combination is set as a duplicate combination in FIG. 5, it is specified only when the number of payouts per game does not belong to any of the winning combinations in FIG. 5 and exceeds the number of payouts of the specific combination Count the hands. In the present embodiment, when there are 15 payouts as duplicated combinations, the specific combination 2 is counted.
Exclusion safe: A safe (corresponding to the number of excluded payouts) obtained by subtracting the number of payouts for the specified combination 1 (2) won during the judgment period from the judgment safe. Note that the number of payouts for a specific role (the number of payouts in a game determined to have won a specific role) = the number of wins for a specific role × the number of payouts shown in FIG. Winning rate ratio (special role 2 wins number / specific role 1 wins number) (corresponds to “game information corresponding to the ratio of the number of wins of the second specific role to the first specific role in a predetermined period”).

  By the way, in order to detect the base abnormality, it is only necessary to obtain the base by excluding the payout amount of the AT combination and the RT combination in which the winning rate fluctuates according to the state of the slot machine 4, but there is a status signal indicating their occurrence. Since it is not output from the slot machine 4 side, the management device 3 determines the base abnormality as follows.

FIG. 10 is a flowchart showing the base abnormality detection process by the management device 3. FIG. 10 shows an operation for detecting a base abnormality of one slot machine 4, but the management device 3 actually executes detection processing in parallel for all the slot machines 4.
When the bonus signal is not being received (S1: NO), the management device 3 has received a safe signal (S2), has received an out signal (S5), or is the game timer in operation (S7) The operation in the state where it is determined whether the small role safe is 0 (S9) and the determination out is 1000 or more (S13) and the bonus signal is not being received will be described below.

  When the player inserts or bets a medal into the slot machine 4 and operates the start lever 15 to use the medal, a corresponding out signal is output from the slot machine 4, so the slot machine 4 receives the out signal. When it is done (S5: YES), the number of outs corresponding to “determination out” corresponding to the corresponding gaming machine ID in the abnormality determination storage area shown in FIG. 7 is added (S6).

When the small winning combination is won as a result of the game, the slot machine 4 pays out the game medium and outputs a safe signal according to the payout.
When the management apparatus 3 receives a safe signal from the gaming machine side (S2: YES), the management apparatus 3 sets 1 to “determination safe” and “small role safe” of the corresponding gaming machine ID in the abnormality determination storage area shown in FIG. Is added (S3), and a game timer is started (S4). This game timer is set to a time that sufficiently anticipates the time required from when the first game medium is paid out in accordance with the winning of a small role from the slot machine 4 to when the last game medium is paid out.

  The management device 3 receives the safe signal (S2: YES) until receiving the out signal while the game timer is in operation (S5: YES) or until the game timer expires (S8: YES). When the safe is added and the out signal is received (S5: YES), or when the game timer is up (S8: YES), it is determined whether the small role safe is 0 (S9). When a small role is won, since the small role safe is not 0 (S9: NO), the small role safe that is the number of payouts for each game is compared with the number of payouts shown in FIG. 5 for each game. The determined small combination is determined (S10), the specific combination winning number is updated (S11), and the small combination safe is set to 0 (S12). That is, when the small combination safe is 3, 1 is added to the specified combination 1 winning number, and when the small combination safe is 6, 1 is added to the specified combination 2 winning number.

In the example shown in FIG. 7, since the small combination safe of the slot machine 4 with the gaming machine IDs “2” and “4” is 6, 1 is added to the specific combination 2 winning number.
As illustrated in FIG. 10, when the determination out becomes 1000 or more (S13: YES), the management device 3 determines whether the determination safe is equal to or higher than the upper limit of abnormality (S14).

  9 (a) to 9 (c) show the winning situation by game of a general player who is a player who does not cheat (by (a) normal state (other than RT or ART), (b) during RT, (C) is an example assumed in ART), and in each case, the determination out is 1000. As shown in FIG. 9A, the judgment safe obtained by adding the number of payouts of each small part is 597 (= 138 + 48 + 228 + 153 + 30). From this judgment safe, the AT part in the replay part, the small part 2 and the overlapping part (in 15 sheets) The exclusion safe minus 6 cards is 219 (= 597-138-228-12), and the standard minority ratio is 82.61% (= 38 ÷ 46).

Accordingly, as shown in FIG. 10, the management device 3 determines that it is normal because the judgment safe (597) is not equal to or higher than the abnormality upper limit value (800) of the model A (S14: NO). And the specific winning number is set to 0 (S18).
As described above, in normal times, abnormality detection can be performed by comparing the judgment safe with the abnormality upper limit value.

  By the way, when the slot machine 4 wins the RT generating combination, the RT state is entered. In this RT state, the winning rate of the replay combination is high, so that the judgment safe is higher than normal. B. After the end of B, the ART state becomes an ART state in which the AT state and the RT state occur simultaneously. In this ART state, the winning rate of the replay combination and the small combination 2 (actually, including the small combinations 3 and 4 and so on) is increased, and in this case as well, the judgment safety is increased compared to the normal time.

  As shown in FIG. 9 (b), during the RT, the determination safe is higher than the abnormal upper limit due to the increase in the winning percentage of the replay combination. Become. Similarly, during ART, because the winnings of the replay combination and the small combination 2 are high, the determination safe exceeds the abnormal upper limit value, so that the determination based on the abnormal upper limit value is determined to be abnormal.

Therefore, as shown in FIG. 10, when the determination safe becomes equal to or higher than the abnormal upper limit (S14: YES), the management device 3 determines whether the exclusion safe is below the exclusion upper limit (S15).
In the example shown in FIG. 9B, the exclusion safe (219) is lower than the exclusion upper limit value (441) of the model A, and in the example shown in FIG. 9C, the exclusion safe (237) is the exclusion upper limit value of the model A. Since it is less than (441), it can be determined that there is no abnormality.

On the other hand, when the winning rate of the small combination 5 is illegally increased, the number of payouts of the small combination 5 is not excluded from the judgment safe, and thus the exclusion safe increases abnormally.
FIG. 9D shows an example of the winning situation when the winning rate of the small combination 5 is illegally increased, and FIG. 9E shows the details of the illegal situation. Since the number of winnings of the small role 5 (131 (of which the number of winnings due to fraud is 120)) is larger than usual, the judgment safe (1460) is equal to or higher than the abnormal upper limit value. In this case, since the judgment safe approximates the judgment safe in ART shown in FIG. 9C, even if the abnormal upper limit value is adjusted, the detection accuracy cannot be maintained.

  However, since the management apparatus 3 does not subtract the number of payouts due to winning of the small role 5 from the judgment safe, it is determined that the exclusion safe (1220) is equal to or higher than the exclusion upper limit value (441) of the model A as shown in FIG. (S15: NO), an abnormality can be detected (S17).

  On the other hand, when the winning rate of the replay role or small role 2 is illegally increased (the replay role has low fraud effect, the small role 2 is targeted), and the number of payouts due to those frauds is determined Since it is subtracted from the safe, the exclusion safe will fall below the exclusion upper limit value, and the abnormality cannot be detected.

  FIG. 9F shows an example of the winning situation when the winning rate of the small combination 2 is illegally increased, and FIG. 9G shows the details of the illegal situation. When the small role 2 is targeted, the number of payouts by the small role 2 is excluded from the judgment safe, so the exclusion safe (92) is below the exclusion upper limit (441), but the standard small role rate (special role 2 The number of winning (small winning 2 winning) / special winning 1 winning (replay winning) is larger than FIG. 9C. Here, the reference small percentage will be described in detail. As can be seen from a comparison of FIGS. 9A and 9C, the reference small percentage is approximated to the value in the normal state even when the winning state of the small combination 2 which is the specific combination 2 is increased to the ART state. ing. This is because, when the slot machine 4 to be managed becomes an ART state in which the winning rate of the specified combination 2 (small role 2) increases, the winning rate of the specified combination 1 (replay combination) also increases. In other words, as described above, the winning rate is higher when the replay role is in a special state than the small role 2, so that as long as a normal game is played, only the replay role is won. Even if there is a case, it will be impossible if only the number of winnings of the small role 2 increases. Therefore, even in the ART state, the normal state and the reference small percentage are approximated. In other words, it can be said that the reference small role ratio is game information that is less affected by the game state compared to other game information in the game information considering the specific combination 2. However, when fraud targeting the small role 2 is performed, the winning number of the replay role is not changed, and only the winning number of the small role 2 is increased, and the standard small role rate is increased. Therefore, if it is determined whether or not the reference small duty ratio is equal to or higher than a predetermined value, an abnormality can be detected accurately regardless of the gaming state.

  Therefore, as shown in FIG. 10, when the exclusion safe falls below the exclusion upper limit value (S15: YES), the management device 3 does not immediately determine that there is no abnormality, and the standard small utilization rate is the abnormality small of the model A. It is determined whether or not the utilization rate upper limit (200%) or more (S16). In this case, since the reference small percentage (1211.11%) is equal to or higher than the abnormal small percentage upper limit (200%), an abnormality can be detected. As the upper limit value (200%) of such an abnormal small role, since the fluctuation range of the standard small role according to the gaming state is small, an allowable value can be set more strictly. In addition, it is possible to detect anomalies with improved fraud detection accuracy.

When the management device 3 detects an abnormality as described above, the management device 3 performs a pop-up display or the like indicating the abnormality on the calling lamp 5 that is a notification means or the display unit of the management device 3, and outputs an abnormality detection output as history information. Update.
FIG. 8 shows an example of an abnormality detection output by the management device 3. Note that the abnormality detection output shown in FIG. 8 is a form that can be displayed on the display unit of the management apparatus 3 or output by output means such as print output by a printer (not shown). As the abnormality detection output, items of “gaming machine ID”, “occurrence time”, “judgment safe”, “exclusion safe”, and “reference minority” are set corresponding to “NO.” .
The example shown in FIG. 8 indicates that an abnormality due to exclusion safe was detected at 12:30 in the slot machine 4 with the gaming machine ID “3”, and at 12:31 in the slot machine 4 with the gaming machine ID “4”. It shows that an abnormality due to the standard minority ratio was detected. In this case, the game information that causes the abnormality detection is output so as to be identifiable (for example, colored, indicated by hatching in FIG. 8).

  According to such an embodiment, the management device 3 may change the winning rate of the specific combination in accordance with the gaming state, and the state signal that can specify that the gaming state is not output from the slot machine 1 side. If it is determined that such a specific combination has won, the abnormality detection is performed based on the exclusion safe that excludes the number of payouts in the game from the determination safe for each predetermined period, so the winning rate varies depending on the game state It is possible to exclude fluctuations with respect to the number of payouts by a specific role. Accordingly, it is possible to accurately detect an abnormality without performing false detection when the winning rate of the winning combination fluctuates according to the gaming state.

  In addition, since the exclusion upper limit value is specified by excluding the specified combination payout from the abnormal upper limit value, it is approximated to the exclusion safe of other gaming machines that are not provided with RT or ART, so that RT or ART is not provided. The same upper limit value (for example, the same for all models) is set (in a lump) for the game models (because the upper limit value should be an approximate value for all models regardless of whether there is a special state) Since the appropriate exclusion upper limit value is specified simply by setting the presence / absence and the winning rate, the setting operation becomes easy. In addition, an abnormal upper limit value can be set while comparing with other game machines. In particular, if only RT is a game model provided as a special state, the specific role is only the replay role, and generally the winning rate of the replay role is 1 / 7.3, and the corresponding safe is a predetermined value such as 3. Therefore, the number of winnings and the specific combination payout in the predetermined period are the same. Therefore, if the value is set as a default value, the exclusion upper limit value can be set only by setting the abnormal upper limit value and setting the presence / absence of RT, and the setting operation becomes easier.

In addition, when it is determined that the AT role (small roles 2 to 4) and the small role 5 have been won in duplicate, a part of the payout amount due to winning the AT role is excluded from the judgment safe. Anomalies can be accurately detected in consideration of interventions and the like.
In the ART state in which the winning rate of the replay role and the AT role overlaps and fluctuates, the game information corresponding to the ratio of the winning number of the AT role with respect to the replay role in the predetermined period does not vary greatly. This is a case where a fraud targeting a specific role excluded from the detection target is performed by comparing the reference small role rate corresponding to the ratio of the number of winnings of the small role 2 with respect to the role and the upper limit value of the abnormal small role rate. Even fraud detection is possible.
Furthermore, if there is no so-called base abnormality, the abnormality detection excluding the specific combination is not performed, so that the processing load on the management device 3 can be reduced while improving the accuracy of abnormality detection.

(Other embodiments)
The present invention is not limited to the above embodiment, and can be modified or expanded as follows.
Although the exclusion safe is referred to as the abnormality detection, the abnormality detection may be performed on the basis of the ratio of the exclusion safe to the determination out (the ratio of the ball that excludes the safe of the specific role). In this case, an allowable value indicating a ratio is set as the allowable value. That is, the payout permission information referred to in the present invention may be information that directly indicates the abnormal upper limit value or the exclusion upper limit value, or may be information that is indirectly indicated.

When fraud is performed, the winning rate of winning combinations other than the small role that is the target of fraud decreases as shown in FIGS. 9D and 9F, and therefore, the allowable value corresponding to the exclusion safe is only the upper limit value. Alternatively, a lower limit value may be set. That is, fraud detection may be performed when the allowable value range is deviated.
Only when a base abnormality is detected in consideration of the processing load of the management device 3, an abnormality detection based on the exclusion safe is performed, and only when the abnormality is detected based on the exclusion safe, the reference minority is verified. However, NO. Each abnormality detection may be performed independently, such as outputting a reference small percentage at l.

The predetermined period for performing the abnormality determination may be specified by the number of games, a timer, or the like.
All numerical values are examples. For example, what is necessary is just to change as needed, such as the setting of an allowable value and the number of specific roles. If the accuracy is not required more than necessary, the winning rate (ratio of the number of winnings with respect to the number of games) may be referred to instead of the standard small percentage. In addition, as the identifiable output in FIG. 8, a known identification method such as adding a mark other than coloring or inverting numbers may be adopted.

  In the case where the specified role and other small roles are won in duplicate, the configuration that excludes the safe for the specified role has been illustrated, but in order to win a duplicate, a certain amount of technical intervention is required. Even if a game is not being played, the player may be biased. Therefore, when multiple winnings are made, all the safes may be excluded and the error may be removed.

Although the gaming machine that does not shift to the AT state alone is exemplified as the management target gaming machine, the gaming machine that shifts to the AT state alone may be the management target. In this case, there is a state in which the winning rate of the AT role and the replay role overlaps with each other, and a period in which the winning rate fluctuation period (RT) of the replay role is longer than the winning rate fluctuation period (AT) of the AT role is set, A gaming machine in which the replay role is given priority is desirable. Further, not only slot machines but also parrot gaming machines can be assumed. In this case, a recovery signal output from the used pachinko ball recovery device may be received as an out signal. The special state may be a special state other than the so-called CT state.
A part or all of the processing of the management device 3 may be performed by a terminal device such as the relay device 1 or the call lamp 5. That is, the concept of the management device in the present invention means a broad management device including these terminal devices.
