Based on the game control result of the game control means, grasping means for grasping the cumulative determination target value in a preset period (winning count storage areas 153c and 153e, and steps S1203 and S1205 in the CPU 151 of the main control device 131, etc. )When,
A game characterized by comprising judgment means (step S1207, step S1208, etc. in the CPU 151 of the main control device 131) for judging and comparing the cumulative judgment target value grasped by the grasping means and a preset reference value. Machine.

  In the gaming machine of the means 27, a privilege is given to the player based on the game result in the gaming device. In this case, the cumulative determination target value in a preset period is grasped based on the game result in the gaming device, and the grasped cumulative judgment target value is compared with a preset reference value. As a result, it is possible to determine whether or not the cumulative determination target value is abnormal with respect to the reference value. For example, if an illegal act that illegally manipulates a game result in a gaming device is performed, the fact is understood. It becomes possible to do. And, by making it possible to grasp such facts, it is possible to take some measures when the above-mentioned fraudulent acts are performed, and to suppress continued fraudulent acts of obtaining benefits using fraudulent devices. It becomes possible.

  The “preset period” includes not only a period from a predetermined timing until a preset time elapses but also a preset end event after a preset start event occurs. The period until is also included. Therefore, for example, in a configuration including a pattern display device that variably displays a pattern as a gaming device, the cumulative determination target value in a preset period includes cumulative determination target values in a plurality of game times. That is, in this case, the preset period is a period for a plurality of game times.

  In addition, in the “game control result”, not only the result of whether or not a privilege is granted based on the game result in the gaming device, but also a state in which a privilege can be granted although it does not reach the privilege grant. The result of whether or not is included.

  Further, the “grasping means” and the “determination means” may be provided independently of the game control means, or may be provided as part of the game control means.

Means 28. A pattern display device (reel unit 41) for variably displaying the pattern;
Starting means (start lever 71) for generating a trigger for variable display of the pattern;
Lottery means (lottery processing in the CPU 151 of the main control device 131) for performing lottery of a combination based on the occurrence of a start trigger by the starter;
A bonus is awarded to a player when the lottery result of the winning combination is a winning combination winning and a winning combination corresponding to the winning winning combination corresponding to the winning winning combination is established at a predetermined effective position in the variable display area of the pattern. In gaming machines that grant
Grasping means (the winning count storage areas 153c and 153e and the step S1203 in the CPU 151 of the main control device 131) for grasping the cumulative determination target value in the plurality of gaming times based on the winning results of winning combinations or winning results in each gaming time S1205)
A game characterized by comprising judgment means (step S1207, step S1208, etc. in the CPU 151 of the main control device 131) for judging and comparing the cumulative judgment target value grasped by the grasping means and a preset reference value. Machine.

  In the gaming machine of the means 28, a lottery of the combination is performed based on the start timing generated by the starting unit, and the lottery result of the combination is a bonus combination winning, and the corresponding bonus combination winning prize is in the effective position. If it is established, a privilege is given to the player.

  In this case, the cumulative determination target value in a plurality of game times is grasped based on the winning result of the combination in each game round or the winning establishment result, and the grasped cumulative judgment target value is compared with a preset reference value. The This makes it possible to determine whether or not the cumulative determination target value is abnormal with respect to the reference value. For example, in the case where a fraudulent act that illegally wins a specific bonus combination is performed, the fact is grasped. It becomes possible. And by making such facts understandable, it becomes possible to take some measures when the above fraudulent acts are performed, and the fraudulent acts of manipulating the lottery result of the role using the fraudulent device continue. This can be suppressed.

  The “game times” refers to the number of times that the variable display of the picture on the picture display device is started (started) based on the occurrence of the start trigger by the starting means.

  Further, as the “starting means”, a starting operation means operated to start variable display of a picture can be considered. In addition to the start operation means, for example, in a configuration in which a game display area is provided with a pattern display device in a game area where a game ball flows down, a start opening installed in the game area is conceivable. In this case, a game ball enters the start opening. Based on the ball, variable display of the pattern on the pattern display device is started.

  With respect to each of the means described above, the application target of each of the means 2 to 26 may be the means 27 or 28 instead of the means 1, and in this case, the means 27 or 28. The structure regarding can be made more favorable.

  The basic configuration of various gaming machines to which the above means can be applied is shown below.

Hereinafter, a first embodiment when applied to a swivel type gaming machine, which is a kind of gaming machine, specifically, a slot machine will be described in detail with reference to the drawings. 1 is a front view of the slot machine 10, FIG. 2 is a perspective view of the slot machine 10, FIG. 3 is a perspective view of the slot machine 10 with the front door 12 opened, FIG. 4 is a rear view of the front door 12, and FIG. FIG. 3 is a front view of the housing 11.

  As shown in FIGS. 1 to 5, the slot machine 10 includes a housing 11 that forms an outer shell thereof. The casing 11 includes a top plate 11a, a bottom plate 11b, a back plate 11c, a left plate 11d, and a right plate 11e formed in a wooden plate shape, and the adjacent plates 11a to 11e are fixed by a fixing means such as an adhesive. As a whole, it is formed in a box shape with the front surface opened.

  A front door 12 as a front open / close door is attached to the front side of the housing 11 so as to be openable and closable. In other words, the left side plate 11d of the housing 11 is provided with a pair of upper and lower support shafts 25a and 25b. Each of the support shafts 25a and 25b includes a tapered shaft portion that protrudes upward. On the other hand, the front door 12 is provided with support fittings 26a and 26b having insertion holes into which the shaft portions of the support shafts 25a and 25b are inserted corresponding to the support shafts 25a and 25b. Then, the support brackets 26a and 26b are arranged above the support shafts 25a and 25b, and the front door 12 is lowered, whereby the shaft portions of the support shafts 25a and 25b are inserted into the insertion holes of the support brackets 26a and 26b. It is assumed that it was done. Thereby, the front door 12 is supported so as to be rotatable about an opening / closing axis extending in the vertical direction connecting the both support shafts 25a and 25b with respect to the housing 11, and the front opening side of the housing 11 is opened by the rotation. It can be closed or closed.

  The front door 12 is brought into a locked state that cannot be opened by a locking device provided on the rear surface. Further, a key cylinder 20 serving as an unlocking operation unit is provided at the upper right side of the front door 12. The key cylinder 20 is integrated with a locking device, and is configured such that the locked state is released by a predetermined key operation on the key cylinder 20. Therefore, an outline of the lock mechanism including the locking device will be described.

  On the right end side of the front door 12, that is, on the opposite side of the opening / closing axis of the front door 12, a locking device is provided on the back surface. The locking device extends vertically and is fixed to the front door 12, a key cylinder 20 provided so as to extend from the upper part of the base frame to the front of the front door 12, and moves vertically with respect to the base frame. It is provided with a long interlocking rod 21 assembled as possible. And only the key cylinder 20 is provided in the state which protruded ahead of the front door 12 among the locking devices. The position where the key cylinder 20 is provided is the thin upper portion of the front door 12, and as a result, a versatile key cylinder 20 having a short overall length can be employed.

  The interlocking rod 21 is moved downward by operating the key inserted into the key cylinder 20 clockwise. The interlocking saddle 21 is provided with a pair of upper and lower saddle fittings 22 having a bowl shape. When the front door 12 is closed with respect to the casing 11, the saddle fitting 22 is supported on the casing 11 side. Is locked. In addition, the urging member 22 is provided with an urging member such as a coil spring for urging to the side maintaining the locked state. When the key is operated clockwise with respect to the key cylinder 20, the interlocking rod 21 moves downward, and the saddle fitting 22 is moved against the biasing force of the biasing member. The locked state with the support fitting 23 is released, and the locked state of the front door 12 with respect to the housing 11 is released.

  A game panel 30 for notifying the player of the game state is provided above the center of the front door 12. In the game panel 30, three vertically long display windows 31L, 31M, 31R are formed side by side. The display windows 31L, 31M, 31R are made of a transparent or translucent material, and the inside of the slot machine 10 is visible through the display windows 31L, 31M, 31R. The display windows 31L, 31M, and 31R may be combined into a single display window.

  As shown in FIG. 3, the inside of the housing 11 is vertically divided into two by a partition plate 40, and a reel unit 41 constituting variable display means is attached to the upper portion of the partition plate 40. The reel unit 41 includes a left reel 42L, a middle reel 42M, and a right reel 42R each formed in a cylindrical shape (annular shape). The reels 42L, 42M, and 42R may be configured as at least an endless belt, and are not limited to a cylindrical shape (annular shape). Each of the reels 42L, 42M, and 42R is rotatably supported so that the central axis thereof is the rotation axis of the reel. The rotation axes of the reels 42L, 42M, and 42R are arranged on the same axis extending in the substantially horizontal direction, and the reels 42L, 42M, and 42R correspond to the display windows 31L, 31M, and 31R on a one-to-one basis. . Accordingly, a part of the surface of each reel 42L, 42M, 42R is visible through the corresponding display windows 31L, 31M, 31R. Further, when the reels 42L, 42M, and 42R are rotated forward, the surfaces of the reels 42L, 42M, and 42R are projected as if moving from top to bottom through the display windows 31L, 31M, and 31R.

  FIG. 6 is an assembled perspective view of the left reel 42L. As shown in the figure, each of the reels 42L, 42M, and 42R is connected to a stepping motor 61L, 61M, and 61R (only the left reel stepping motor 61L is shown in FIG. 6). , 61M, 61R, the reels 42L, 42M, 42R can be rotated individually, that is, independently.

  The left reel 42L includes a cylindrical skeleton member 50 that forms a cylindrical cage, and a belt-like belt wound endlessly on the outer peripheral surface thereof. And it is affixed on the cylindrical skeleton member 50 through a pair of seal parts formed along the both sides of the long side of the belt so as to maintain the wound state. A large number of symbols as identification information are printed at equal intervals on the outer peripheral surface of the belt. A boss 51 is formed at the center of the cylindrical skeleton member 50, and is attached to the drive shaft of the left reel stepping motor 61L via a disk-like boss reinforcing plate 52. Accordingly, when the drive shaft of the left reel stepping motor 61L is rotated, the cylindrical skeleton member 50 is rotated around the drive shaft so that the left reel 42L circulates along the annular reel surface. It has become.

  The left reel stepping motor 61L is fixed to the side surface of the motor plate 53 arranged in an upright state in the reel unit 41 (FIG. 3) with screws 54. The motor plate 53 is provided with a reel index sensor (rotational position detection sensor) 55 in which a light emitting element 55a and a light receiving element 55b are held at a predetermined interval. On the other hand, the base end portion 56b of the sensor cut bun 56 extending in the radial direction is fixed to the boss reinforcing plate 52 integrated with the left reel 42L with a screw 57. The front end portion 56a of the sensor cut bun 56 is bent at a substantially right angle and is positioned so as to pass between both elements 55a and 55b of the reel index sensor 55. Each time the left reel 42L makes one rotation, the reel index sensor 55 detects the passage of the front end portion 56a of the sensor cut bun 56, and a detection signal is output to the main controller 131 described later each time the detection is made. Therefore, main controller 131 can confirm and correct the angular position of left reel 42L for each rotation based on this detection signal.

  The stepping motor 61L is set to rotate once by giving, for example, a drive signal of 504 pulses (also referred to as an excitation signal or an excitation pulse; the same applies hereinafter), and the rotation position of the stepping motor 61L, that is, left The rotational position of the reel 42L is controlled.

  On each belt of each of the reels 42L, 42M, and 42R, a plurality of, specifically, 21 symbols are drawn in the long side direction (circumferential direction). Therefore, 24 pulses (= 504 pulses ÷ 21 symbols) are required to switch from one symbol to the next symbol at a predetermined position. Based on the number of pulses from when the detection signal of the reel index sensor 55 is output, it is recognized which symbols are visible from the display windows 31L, 31M, and 31R, and arbitrary symbols are displayed on the display window. Control to make it visible from 31L, 31M, 31R can be performed.

  Of the symbols attached to the reels 42L, 42M, and 42R, the number of symbols that can be visually recognized through the display windows 31L, 31M, and 31R is mainly determined by the vertical lengths of the display windows 31L, 31M, and 31R. Is limited to a predetermined number. In this embodiment, three reels are provided. For this reason, when all the reels 42L, 42M, and 42R are stopped, 3 × 3 = 9 symbols are visible to the player.

  Here, the symbols attached to the reels 42L, 42M, and 42R will be described. FIG. 7 shows a symbol arrangement drawn on the belt wound around each of the left reel 42L, the middle reel 42M, and the right reel 42R. As shown in the figure, each of the reels 42L, 42M, and 42R is provided with 21 symbols in a row. In addition, numbers 0 to 20 are assigned to the reels 42L, 42M, and 42R, and these numbers are used for the main controller 131 to recognize the symbols that are visible from the display window. It is a number and is not actually attached to the reels 42L, 42M, 42R. However, in the following description, the number is used for explanation.

  The symbols include “Replay” symbol (for example, left belt 20th), “Bell” symbol (for example, left belt 19th), “Youth” symbol (for example, left belt 18th), “7” symbol (for example, (Left belt 17th), “Cherry” design (eg, left belt 13th), “Chance” design (eg, left belt 12th), “Watermelon” design (eg, left belt 9th), “Reach” design ( For example, there are nine types: the 6th left belt) and the “Lucky” symbol (for example, 1st left belt). As shown in FIG. 7, the number of symbols and the arrangement order of the various symbols are completely different in the belts wound around the reels 42L, 42M, and 42R.

  Each reel 42L, 42M, 42R of the reel unit 41 is an example of variable display means for variably displaying identification information, and constitutes a main display unit. However, the variable display means may have a configuration other than this as long as the symbol is variably displayed in the circumferential direction. For example, other mechanical reel configurations such as a type in which the belt is rotated instead of rotating may be used. In addition to the mechanical reel configuration, an electric display such as a liquid crystal display or a dot matrix display may be used. A device for variably displaying the identification information may be provided, and in this case, it is possible to give abundant variations in the display form.

  A total of five combination lines are attached to the game panel 30 such that three display windows 31L, 31M, and 31R are connected to each other and three in parallel in the horizontal direction and two in diagonal directions. Of course, the maximum number of combined lines may be 6 or more, or less than 5, and the maximum number of combined lines may be changed according to a predetermined condition. Corresponding to these combination lines, effective line display sections 32, 33, and 34 are provided on the left side when viewed from the front of the display windows 31L, 31M, and 31R. The first effective line display unit 32 is notified by lighting or the like when the central horizontal line (middle line) of the combination lines is activated. When the upper and lower horizontal lines (upper line and lower line) of the combination lines are activated, the second effective line display unit 33 is displayed and notified by lighting or the like. The third effective line display unit 34 is notified by lighting or the like when a pair of diagonal lines (downward right line and upward right line) of the combination lines is activated. And, when the combination line that has been activated, that is, when the symbol is stopped in a predetermined combination on the activated line, a prize is awarded, and a payout process for a predetermined medal number or a bonus game such as a BB game that is in a special gaming state is awarded. Migration processing etc. are executed.

  FIG. 8 shows a combination of symbols for winning and the number of medals to be paid out when winning.

  Small prizes for which medals are paid out include a watermelon prize, a bell prize, and a cherry prize. When stopped alongside the “Watermelon” symbol, “Watermelon” symbol, and “Watermelon” symbol from the left on the active line, 15 medals are paid out as a watermelon prize, “Bell” symbol from the left, “Bell” on the active line In the case of stopping alongside the symbol and the “bell” symbol, eight medals are paid out as a bell prize. When the “cherry” symbol on the left reel 42L stops on the active line, four medals are paid out as a cherry prize. That is, in the case of a cherry winning, any symbol that stops on the active line of the middle reel 42M and the right reel 42R may be any symbol. Therefore, when the “cherry” symbol stops at the position where the plurality of effective lines of the left reel 42L overlap (specifically, the upper stage or the lower stage), a cherry winning is established on each active line, and the overlapping effective The medal is paid out by multiplying the number of lines. As a result, in this embodiment, eight medals are paid out.

  Further, there is a BB winning as a state transition winning in which the gaming state shifts. When stopped alongside the “7” symbol, “7” symbol, and “7” symbol from the left on the active line, the game state shifts from the normal game as the normal game state to the BB game as the special game state as a BB prize To do. However, even if the “7” symbol stops along the left, middle and right on the active line, no medal is paid out. That is, when the combination of the “7” symbols is established on the active line, only the BB game is entered. In other words, it can be said that the “7” symbol is a state transition symbol for shifting the gaming state to the BB game.

  Furthermore, when the “replay” symbol, “replay” symbol, and “replay” symbol are stopped from the left on the active line, a re-game win is awarded. When the re-game winning is established, the medal payout and the state transition are not performed, but the player can play the next game without reducing the medals owned and without inserting medals.

  In other cases, that is, when the “cherry” symbol of the left reel 42L does not stop on the active line and the combination of the symbols described above does not stop on the active line, the medal payout, the transition of the gaming state, etc. Not done at all. That is, the “chance” symbol and “lucky” symbol of the left reel 42L and the right reel 42R, the “cherry” symbol of the middle reel 42M and the right reel 42R, the “youth” symbol and the “reach” symbol of each reel 42L, 42M, 42R. Is not involved in any winnings. In other words, it can be said that each of the symbols is a no-benefits symbol unrelated to the privilege given to the player. As described above, each of the reels 42L, 42M, and 42R is provided with a bonus symbol related to winning such as a “bell” symbol and a non-privileged symbol irrelevant to winning such as a “young” symbol, for example. In the following, a combination of symbols corresponding to each prize is also referred to as a combination of winning symbols. For example, the BB symbol combination is a symbol BB winning combination, that is, a combination of “7” symbol, “7” symbol, and “7” symbol.

  On the lower left side of the game panel 30, a start lever 71 is provided that is operated to start rotation of the reels 42L, 42M, and 42R all at once (not necessarily simultaneously). The start lever 71 constitutes start operation means or start operation means operated to start rotation of the reels 42L, 42M, and 42R, that is, to start variable display. The start lever 71 is a lever that is pushed by the hand when the player starts the game, and automatically returns to the original position after the hand is released. When the start lever 52 is operated while a medal is inserted, the reels 42L, 42M, and 42R start to rotate all at once.

  On the right side of the start lever 71, button-like stop switches 72, 73, 74 that are operated to individually stop the rotating reels 42L, 42M, 42R are provided. Each of the stop switches 72, 73, 74 is arranged directly below the display windows 31L, 31M, 31R corresponding to the reels 42L, 42M, 42R to be stopped. That is, when the left stop switch 72 is operated, the rotation of the left reel 42L is stopped. When the middle stop switch 73 is operated, the rotation of the middle reel 42M is stopped and the right stop switch 74 is operated. In this case, the rotation of the right reel 42R is stopped. The stop switches 72, 73, 74 constitute stop operation means operated to stop variable display based on the rotation of the reels 42L, 42M, 42R. Each of the stop switches 72, 73, 74 can be stopped when a predetermined time elapses after the left reel 42L starts rotating, and is stopped by lighting a lamp (not shown) during such a state. It is notified that the operation is possible, and is turned off when the rotation stops.

  On the lower right side of the display windows 31L, 31M, 31R, there is provided a medal slot 75 for inserting a medal as an investment value. The medal slot 75 constitutes an input means for inputting the investment value. Further, if attention is paid to the point that the medal insertion slot 75 is accompanied by the operation of directly inserting the medal by the player, it can be said that the medal insertion slot 75 constitutes a direct input means for directly inputting the investment value.

  The medals inserted from the medal insertion slot 75 are guided to either the storage passage 81 or the discharge passage 82 by the selector 84 as passage switching means provided on the back surface of the front door 12. That is, the selector 84 is provided with a medal path switching solenoid 83, which is set to the discharge path 82 side when the medal path switching solenoid 83 is not excited, and switched to the storage path 81 side when excited. The medal guided to the storage passage 81 is guided to the hopper device 91 housed in the housing 11. On the other hand, the medal guided to the discharge passage 82 is guided to the medal tray 18 from the medal discharge port 17 provided in the lower front portion of the front door 12 and returned to the player.

  The medal tray 18 is opened upward and has a capacity capable of storing a large amount of medals. A lower plate 16 on which a model name, a character related to a game, and the like are displayed is mounted above the medal tray 18.

  A hopper device 91 as a payout means for giving a medal to a player is composed of a storage tank 92 for storing the medal and a payout device 93 for paying out the medal to the player. The payout device 93 rotates a medal payout rotating plate (not shown) to discharge the medal to the opening 94 provided in the central right part of the discharge passage 82 and to the medal tray 18 through the discharge passage 82. To come out. Further, a reserve tank 95 is provided on the right side of the hopper device 91 in order to avoid storing a predetermined amount or more of medals in the storage tank 92. A guide plate 96 for discharging medals from the storage tank 92 to the reserve tank 95 is provided inside the storage tank 92 of the hopper device 91. Therefore, when medals are stored more than the height at which the guide plate 96 is provided, the medals are stored in the reserve tank 95.

  A button-like return switch 76 is provided below the medal slot 75. The return switch 76 is a switch that is pressed when a medal inserted into the medal slot 75 is jammed in the selector 84. When this switch is pressed, the selector 84 is mechanically operated to operate the selector 84. The medals packed in 84 are returned from the medal discharge port 17.

  On the lower left side of the display windows 31L, 31M, 31R, there is provided a button-like first credit insertion switch 77 for inserting three virtual medals credited as investment values at a time. Further, on the left side of the first credit insertion switch 77, a second credit insertion switch 78 and a third credit insertion switch 79 are provided as button switches smaller than the switch 77. The second credit insertion switch 78 is for inserting two credited virtual medals at a time, and the third credit insertion switch 79 is for inserting one virtual medal. Each of the credit insertion switches 77 to 79, together with the medal insertion slot 75, constitutes an input means for inputting an investment value. Further, if the medal insertion slot 75 is accompanied by an operation of directly inserting a medal by the player, each credit insertion switch 77 to 79 is only accompanied by an operation of inserting a virtual medal based on the storage memory. It can also be said that it constitutes an indirect input means for indirectly inputting the investment value.

  A button-like settlement switch 80 is provided on the left side of the start lever 71. That is, the slot machine 10 has a credit function for storing and storing surplus inserted medals up to a predetermined maximum value (for 50 medals) and winning medals as virtual medals. The virtual medal is paid out as an actual medal when the settlement switch 80 is pressed while stored and stored. In this case, if paying attention to the function of paying out the credited virtual medal as an actual medal, it can be said that the checkout switch 80 constitutes a checkout operation means for actually paying out the stored game value.

  Below the display windows 31L, 31M, and 31R of the game panel 30, a credit display unit 35 that displays the number of virtual medals stored and stored, and the remaining number of acquired medals that displays the number of remaining medals that can be acquired before the BB game is over. A display unit 36 and an acquired number display unit 37 for displaying the number of medals acquired at the time of winning are provided.

  Here, a procedure for betting medals will be described. If a medal is inserted from the medal slot 75 at the start of the game, a bet is placed.

  That is, when the first medal is inserted into the medal insertion slot 75, the first effective line display section 32 is turned on, and the corresponding middle line becomes the effective line, and the second medal is the medal insertion slot. When the number 75 is inserted, the second effective line display section 33 is turned on, and a total of three combination lines including the upper line and the lower line corresponding to the second effective line display section 33 become effective lines, respectively, and the third medal is a medal. When it is inserted into the insertion port 75, the third effective line display unit 34 is further turned on, and a total of five combination lines including a pair of diagonal lines corresponding thereto become effective lines.

  When four or more medals are inserted into the medal slot 75, surplus medals exceeding three are stored inside the slot machine if the number of virtual medals stored and stored at that time is less than 50. At the same time, the number of virtual medals on the credit display unit 35 is added and displayed. On the other hand, when the number of virtual medals is 50 or reaches 50, the selector 84 switches from the storage passage 81 to the discharge passage 82, and the surplus medals are returned from the medal discharge port 17 to the medal tray 18. Is done.

  Further, when the stored number is displayed on the credit display unit 35, a virtual medal is inserted even when any of the first to third credit insertion switches 77 to 79 is pressed, and a bet is made. .

  When the third credit insertion switch 79 is pressed, the numerical value displayed on the credit display unit 35 is decremented by one as a virtual medal is inserted, and the first effective line display unit 32 is turned on. The middle line becomes the active line. When the second credit insertion switch 78 is pressed, two numerical values displayed on the credit display unit 35 as two virtual medals are inserted are subtracted, and the first valid line display unit 32 and the second The effective line display unit 33 is turned on, and a total of three combination lines become effective lines. When the first credit insertion switch 77 is pressed, three numerical values displayed on the credit display unit 35 are subtracted as three virtual medals are inserted, and all the effective line display units 32 to 34 are displayed. Lights up and a total of five combination lines become effective lines.

  In addition, when the virtual medal to be inserted when any of the first to third credit insertion switches 77 to 79 is pressed is not stored, for example, when the display of the credit display unit 35 is 2, the first credit For example, when the insertion switch 77 is pressed, all the numerical values in the credit display unit 35 are subtracted to 0, and a bet is placed for the virtual medal that can be inserted.

The power switch 122 is a start switch for supplying power to each unit including the main controller 131. The reset switch 123 is a switch for resetting an error state of the slot machine 10. The winning probability setting key insertion hole 124 is used by a hole manager or the like to adjust the appearance of medals. That is, the hall manager or the like can set the winning probability of the slot machine 10 by inserting the winning probability setting key into the winning probability setting key insertion hole 124 and turning it ON. The monitoring reset switch 125 is a switch for resetting an error state when a second abnormality process described later is executed. The monitoring state setting key insertion hole 126 is used by a hole manager or the like to adjust an unauthorized monitoring level using the monitoring state setting key. The reset switch 123 is operated not only when resetting the error state but also when changing the winning probability of the slot machine 10 or when changing the monitoring level.

  A main controller 131 is attached to the back plate 11 c of the housing 11 above the reel unit 41. The main control device 131 includes a CPU that controls the main control, a ROM that stores a game program, a RAM that temporarily stores necessary data according to the progress of the game, a port that communicates with various devices, time counting and synchronization. A main board including a clock circuit and the like used in the case of planning is provided, and the main board is accommodated in a board box as an encapsulating means made of a transparent resin material or the like. The board box includes a substantially rectangular parallelepiped box base and a box cover that covers an opening of the box base. The box base and the box cover are connected to each other so as not to be opened by a sealing unit as a sealing means, whereby the substrate box is sealed. In addition, it is good also as a structure which connects a box base and a box cover so that opening is impossible using a key member.

  Next, the electrical configuration of the slot machine 10 will be described based on the block diagram of FIG.

  The main control device 131 is equipped with a microcomputer centering on a CPU 151 as arithmetic processing means. In addition to the power supply device 161 provided in the power supply box 121, the CPU 151 is connected to a random number counter 154 that generates a random number within a predetermined upper limit range and appropriately updates it, and the like via an internal bus. The main control device 131 functions as a main base incorporated in the slot machine 10. The main controller 131 is provided with an input / output port (not shown), and various signals are input / output through the input / output port.

  That is, on the input side of the main controller 131, a start detection sensor 71a that detects the operation of the start lever 71, stop detection sensors 72a, 73a, and 74a that individually detect the operations of the stop switches 72, 73, and 74, medals An insertion medal detection sensor 75a for detecting medals inserted from the insertion slot 75, credit insertion detection sensors 77a, 78a, 79a for individually detecting operations of the respective credit insertion switches 77, 78, 79, and an operation of the settlement switch 80 are detected. The payment detection sensor 80a, the payout detection sensor 91a for detecting medals paid out from the hopper device 91, the reset detection sensor 123a for detecting the operation of the reset switch 123, and the winning probability setting key insertion hole 124.

Various sensors such as 126a are connected, and signals from these various sensors are output to the CPU 151 via an input / output port.

  Further, a power failure monitoring circuit 161 b provided in the power supply device 161 is connected to the input side of the main control device 131. The power supply device 161 includes a power supply unit 161 a that supplies driving power to the electronic devices of the slot machine 10 including the main control device 131, the power failure monitoring circuit 161 b described above, and the like.

  The power failure monitoring circuit 161b is for monitoring the power-off state and generating a power failure signal not only at the time of power failure but also at the time of power-off by the power switch 122. For this reason, the power failure monitoring circuit 161b monitors the stabilized drive voltage of 12 VDC in this example output from the power supply unit 161a, and determines that the power supply is shut off when the drive voltage drops below, for example, 10 volts. Power outage signal is output. The power failure signal is supplied to the CPU 151, and the CPU 151 recognizes this power failure signal and executes a power failure process described later.

  The power supply unit 161a is configured to output a stabilized voltage of 5 volts used as a drive voltage in a control system such as the main control device 131 even when the output voltage is reduced to less than 10 volts. As a time for outputting the stabilization voltage, a time sufficient for executing the power failure process by the main controller 131 is secured.

  On the output side of the main controller 131, each of the effective line display units 32, 33, 34, the credit display unit 35, the remaining acquired number display unit 36, the acquired number display unit 37, and the reels 42L, 42M, 42R is rotated. Stepping motors 61 (61L, 61M, 61R), a medal path switching solenoid 83 provided in the selector 84, a hopper device 91, a display control device 111, an external concentration terminal plate 171 capable of transmitting information to a hall management device (not shown), etc. Etc. are connected.

  The display control device 111 is a control device for driving the upper lamp 13, the speaker 14, and the auxiliary display unit 15, and includes a substrate in which a CPU, a ROM, a RAM, and the like for driving these are integrated. Then, after receiving a signal from the main control device 131, the display control device 111 independently drives and controls the upper lamp 13, the speaker 14, and the auxiliary display unit 15. Therefore, the display control device 111 is a sub-base that executes auxiliary control in relation to the main control device 131 that is a main base that manages and manages games. In other words, the sub-base is provided for voice, lamp, and display related to indirect games, thereby reducing the burden on the main base. In addition, it is good also as a structure which the display control apparatus 111 controls the various display parts 32-37.

  The CPU 151 described above stores various control programs executed by the CPU 151 and a ROM 152 storing fixed value data, and temporarily stores various data when the control program stored in the ROM 152 is executed. In addition to the RAM 153 for securing the area, although not shown, various processing circuits necessary for the slot machine 10 such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit, as well known, and a credit counter for counting the number of credits are known. Various counters such as are built-in. The ROM 152 and RAM 153 constitute a main memory as storage means.

  The ROM 152 stores a program for executing various processes shown in the flowcharts of FIG. 10 and subsequent figures, and further stores various data groups such as a reference value data group 152a. The reference value data group 152a includes various reference values used in an abnormality determination process (FIG. 23) described later.

  The RAM 153 is a memory for temporarily storing various data, and when the power is shut down due to the occurrence of a power failure or the like, the power is shut off (including power shut-down by operating the power switch 122, and so on). A backup area is provided for storing the stack pointer value. Note that a power failure signal from the power failure monitoring circuit 161b is input to the NMI terminal (non-maskable interrupt terminal) of the CPU 151 when the power is interrupted due to the occurrence of a power failure or the like. NMI interrupt processing as flag generation processing is immediately executed.

  Further, the RAM 153 is provided with a winning flag storage area 153a for storing winning flags corresponding to various combinations, and further stores a lottery result history in a lottery process (FIG. 17) to be described later for a plurality of game times. There are provided history storage areas 153b and 153d for storing a plurality of game times and the number of winning times storing areas 153b and 153e for storing a predetermined number of winning times. The history storage areas 153b and 153d and the winning count storage areas 153c and 1533e are provided corresponding to the gaming state. That is, the normal history storage area 153b and the normal winning count storage area 153c are provided for the normal game, and the BB history storage area 153c and the BB winning count storage area 153e are provided for the BB game. Yes. Details of the history storage areas 153b and 153d and the winning count storage areas 153c and 153e will be described later.

  Next, each control process executed by the CPU 151 in the main control device 131 will be described with reference to the flowcharts in FIGS. The processing of the CPU 151 is broadly divided into a main processing that is started when the power is turned on, a timer interrupt processing that is started periodically (in a cycle of 1.49 msec in the present embodiment), and an NMI terminal (non-maskable terminal). For convenience of explanation, the NMI interrupt process and the timer interrupt process will be described first, and then the main process will be described.

  FIG. 10 is a flowchart showing an example of the NMI interrupt process. When the power is shut off due to the occurrence of a power failure or the like, the power failure monitoring circuit 161b of the power supply device 161 generates a power failure signal and outputs it to the main controller 131. In the main controller 131 that has received the power failure signal via the NMI terminal, NMI interrupt processing is executed.

  In the NMI interrupt processing, first, in step S 101, the data of the used register provided in the CPU 151 is saved in the backup area provided in the RAM 153. Subsequently, in step S102, the power failure flag is set in a power failure flag storage area provided in the RAM 153. Thereafter, the data saved in the backup area of the RAM 153 in step S103 is restored to the use register of the CPU 151 again. With this return processing, the NMI interrupt processing ends.

  FIG. 11 is a flowchart of timer interrupt processing periodically executed by the main control device 131, and a timer interrupt is generated by the CPU 151 of the main control device 131 every 1.49 msec, for example.

  First, in the register saving process shown in step S201, the values of all the registers in the CPU 151 used in the normal process described later are saved in the backup area of the RAM 153. In step S202, it is confirmed whether or not a power failure flag is set. If the power failure flag is set, the process proceeds to step S203, and a power failure process is executed.

  Here, the power failure process will be described with reference to FIG. Since the power failure process is performed immediately after the register saving process in the timer interrupt process, other interrupt processes can be executed without interruption. Therefore, for example, during the process of transmitting various commands, during the process of reading the switch state (on / off), the process at the time of power failure is not executed by interrupting each process. It is no longer necessary to create a power failure processing program that also takes into account This simplifies the processing program for power failure processing and reduces the program capacity. This also applies to a processing program for power recovery processing described later.

  In step S301, it is determined whether command transmission has been completed. If the transmission has not been completed, this process is terminated and the process returns to the timer interrupt process to terminate the command transmission. If step S301 is YES, that is, if the command transmission is completed, the process proceeds to step S302, and the value of the stack pointer of the CPU 151 is stored in the backup area in the RAM 153. Thereafter, in step S303, a RAM determination value, which will be described later, is cleared as a stop process, and the output state of the output port in the input / output port is cleared, and all actuators (not shown) are turned off. In step S304, a RAM determination value is calculated and stored in the backup area. The RAM determination value is specifically a 2's complement of the checksum at the work area address of the RAM 153. By storing the RAM determination value in the backup area, the checksum of the RAM 153 becomes zero. By setting the checksum of the RAM 153 to 0, subsequent RAM access is prohibited in step S305. After that, an infinite loop is entered in preparation for the case where the power supply is completely shut down and processing cannot be executed.

  Returning to the description of the timer interrupt process, if the power failure flag is not set in step S202, various processes after step S204 are performed.

  That is, in step S204, a watchdog timer clearing process for initializing the value of the watchdog timer for monitoring the occurrence of malfunction is performed. In step S205, an interrupt end declaration process is performed to enable the next timer interrupt to be set for the CPU 151 itself. In step S206, in order to rotate the reels 42L, 42M, and 42R, a stepping motor control process for driving the stepping motors 61L to 61R, which are the respective rotary drive motors, is performed. In step S207, the state of various sensors (see FIG. 9) connected to the input / output port is read, and sensor monitoring processing is performed to monitor whether the read result is normal. In step S208, when a valid ON signal is received from the start detection sensor 71a in the sensor monitoring process in step S207, the random number acquisition for storing the random number for lottery updated this time in the random number counter 154 is obtained. Process.

  Here, the random number counter will be briefly described. In the slot machine 10, random numbers from 0 to 65535 are generated using two 8-bit shift registers. Each shift register is updated one by one periodically (for example, every 100 ns), a value obtained by switching the upper bit and the lower bit of each shift register is input to the CPU 151, and the start lever 71 is operated (that is, the start detection sensor 71a). (When the ON signal is received) is acquired as a random number for lottery.

  In step S209, a timer calculation process for subtracting the value of each counter or timer is performed. In step S210, counter processing for outputting the result of counting the number of medals bet and the number of payouts to the external concentration terminal board 171 is performed. In step S211, command output processing for transmitting various commands to the display control device 111 is performed. In step S212, a segment data setting process for setting segment data to be displayed on the credit display unit 35, the remaining acquired number display unit 36, and the acquired number display unit 37 is performed. In step S213, the segment data set processing in the segment data setting processing is supplied to the display units 35 to 37, and the segment data display processing for displaying the corresponding numbers, symbols, etc. is performed. In step S214, port output processing for outputting data corresponding to the I / O device is performed. In step S215, the value of each register saved in the backup area in the previous step S201 is restored to the corresponding register in the CPU 151. Thereafter, in step S216, an interrupt permission process for permitting the next timer interrupt is performed, and this series of timer interrupt processes is terminated.

  FIG. 13 is a flowchart showing a main process in the main controller 131 that is executed after the power is turned on. The main process is executed when the power is turned on by recovery from a power failure or by turning on the power switch 122.

  First, in step S401, as initialization processing, the value of the stack pointer is set in the CPU 151, and an interrupt mode that permits interrupt processing is set. Thereafter, various settings for the register group in the CPU 151, the I / O device, and the like are set. Etc.

  When these initialization processes are finished, in step S402, whether or not the winning probability setting key is inserted into the winning probability setting key insertion hole 124 and is turned ON, more specifically, an ON signal is sent from the winning probability setting key detection sensor 124a. It is determined whether it is received. If the ON operation of the winning probability setting key has been performed, the process proceeds to step S403, and all data stored in the RAM 153 is cleared as a forced RAM clear process. In subsequent step S404, a winning probability setting process is performed.

  Here, the winning probability setting process will be described with reference to FIG. The slot machine 10 is prepared in advance with six stages of winning probabilities from “Setting 1” to “Setting 6”, and the winning probability setting process sets which of the winning probabilities is used to execute internal processing. It is a process to do.

  In step S501, the next timer interrupt is permitted. Thereafter, the current winning probability setting value is read in step S502, and the current winning probability setting value is displayed on the credit display unit 35 in step S503. However, in the process immediately after the setting key is inserted and turned ON, the data in the RAM 153 is cleared by the previous forced RAM clear process, so the set value displayed on the credit display unit 35 is “1”. is there.

  In step S504, it is determined whether or not the start lever 71 has been operated. If the start lever 71 has not been operated, a winning probability set value update process shown in steps S505 to S506 is performed. In step S505, it is determined whether or not the reset switch 123 has been operated. If the reset switch 123 is not operated, the process directly returns to step S503. If the reset switch 123 is operated, the winning probability set value is updated by “1” in step S506, and then the process returns to step S503. That is, in the winning probability setting value update process, the winning probability setting value is updated by “1” every time the reset switch 123 is operated, and the updated winning probability setting value is displayed on the credit display unit 35. If the reset switch 123 is operated when the winning probability setting value is “6”, the setting value is updated to “1”.

  If the start lever 71 is operated in step S504, it is determined in step S507 whether or not the ON operation of the winning probability setting key is continued. If the ON operation of the winning probability setting key is continued, the process waits as it is, and if the ON operation is ended, the next timer interruption is prohibited in step S508. Thereafter, the winning probability setting value is stored in step S509, data other than the winning probability setting value stored in the RAM 153 is cleared in step S510, and this process is terminated.

  Returning to the description of the main process, after performing the winning probability setting process in step S404, the process proceeds to step S405. In step S405, it is determined whether or not the monitoring state setting key is inserted into the monitoring state setting key insertion hole 126 and turned ON, and more specifically, whether or not the ON signal is received from the monitoring state setting key detection sensor 126a. . If the monitoring state setting key is turned on, the process proceeds to step S406, and after executing the monitoring state setting process, a normal process for performing main control related to the game is executed in step S407. If the monitoring state setting key is not turned on, the process proceeds to step S407 and normal processing is executed.

  Here, the monitoring state setting process will be described with reference to FIG. In the slot machine 10, by performing an abnormality determination process, which will be described later, an act of illegally obtaining profits is monitored, and the continuous execution thereof is suppressed. The slot machine 10 is prepared in advance with two levels of monitoring levels, “Setting 1” and “Setting 2”. The monitoring state setting process executes an abnormality determination process to be described later based on any monitoring level. This is a process for setting whether or not to be performed.

  In step S601, the next timer interrupt is permitted. Thereafter, in step S602, the current monitoring state setting value is read, and in step S603, the current monitoring state setting value is displayed on the credit display unit 35. The area for displaying the monitoring state setting value is the same as the area for displaying the winning probability setting value in the winning probability setting process as described above, but is not limited to this configuration, and these display areas are different. It is good also as a structure.

  In step S604, it is determined whether or not the start lever 71 has been operated. If the start lever 71 has not been operated, the monitoring state set value update processing shown in steps S605 to S606 is executed. In step S605, it is determined whether or not the reset switch 123 has been operated. If the reset switch 123 has not been operated, the process directly returns to step S603. If the reset switch 123 has been operated, the monitoring state setting value is switched in step S606, and then the process returns to step S603. That is, in the monitoring state setting value update process, the monitoring state setting value is switched between “1” and “2” each time the reset switch 123 is operated.

  When the start lever 71 is operated in step S604, it is determined in step S607 whether the monitoring state setting key is continuously turned on. When the ON operation of the monitoring state setting key is continued, the process waits as it is, and when the ON operation is ended, the next timer interruption is prohibited in step S608. Thereafter, the monitoring state setting value is saved in step S609, and the history storage areas 153b and 153d and the winning count storage areas 153c and 153e of the RAM 153 are cleared in step S610, and the monitoring state setting process ends.

  Returning to the description of the main process, if the winning probability setting key is not inserted in step S402, the power recovery process shown in step S408 and thereafter is performed. The power recovery process is a process for returning the state of the slot machine 10 to the state before the power is shut off. Therefore, in the power recovery process, it is necessary to first check whether the data in the RAM 153 is normal.

  In step S408, it is determined whether the set value is normal. Specifically, when the winning probability setting value is any one of “1” to “6”, it is determined to be normal, and when it is “0” or “7” or more, it is determined to be abnormal. If the set value is normal, it is confirmed in step S409 whether or not a power failure flag is set. If the power failure flag is set, it is further confirmed in step S410 whether or not the RAM determination value is normal. Specifically, the checksum value of the RAM 153 is checked to check whether the value is normal, that is, whether the checksum value including the RAM determination value is 0. If the checksum value including the RAM determination value is 0, it is determined that the data in the RAM 153 is normal.

  If it is determined in step S410 that the RAM determination value is normal, the process proceeds to step S411, where the stack pointer value stored in the backup area is written into the stack pointer of the CPU 151, and the stack state before the power is shut off is written. Return to the state. Next, in step S <b> 412, a power recovery command that tells execution of power recovery processing is transmitted to the display control device 111. Thereafter, in step S413, the game state is stopped and the automatic settlement setting storage process is performed, and in step S414, various sensors such as the start detection sensor 71a are initialized. In subsequent step S415, the power failure flag is reset, and the process proceeds to step S416. In step S416, it is determined whether or not the monitoring state setting key is inserted into the monitoring state setting key insertion hole 126 and is turned ON, and if it is not turned ON, the processing returns to the address before the power is turned off. As a specific process for returning to the address before power-off, the process returns to the timer interrupt process described above, and a watchdog timer clear process (step S204) is executed. If the ON operation has been performed, the monitoring state setting process is executed in step S417, and then the address before power-off is returned. The monitoring state setting process is as described above.

  Here, as described above, the power supply box 121 is provided with each of the winning probability setting key insertion hole 124 and the monitoring state setting key insertion hole 126. In the main process, as described above, the monitoring state setting process can be executed regardless of whether the winning probability setting key is inserted into the winning probability setting key insertion hole 124 or not. With this configuration, it is possible to independently change the winning probability setting value and the monitoring state setting value.

  In the main process, any of step S408 to step S410 is NO, that is, the winning probability set value is abnormal, the power failure flag that is set when the power is shut off is not set, or the RAM judgment value is abnormal In some cases, there is a high possibility that the data in the RAM 153 has been destroyed. In such a case, the operation prohibiting process shown in steps S418 to S420 is performed. As the operation prohibition process, first, the next timer interrupt process is prohibited in step S418, and in step S419, all the output ports in the input / output port are cleared, so that all actuators connected to the input / output port are turned off. To control. Thereafter, in step S420, an error notification process for notifying the hole manager or the like of the occurrence of an error is performed. This operation prohibition state is maintained until the above-described winning probability setting process is performed.

  Next, normal processing for performing main control related to the game will be described based on the flowchart of FIG.

  First, in step S701, it is determined whether or not a medal is bet. If a medal is bet, it is subsequently determined in step S702 whether the start lever 71 has been operated. If both step S701 and step S702 are YES, the lottery process in step S703, the abnormality determination process in step S704, the reel control process in step S705, the medal payout process in step S706, and the BB game process in step S707 are executed in order. Return to step S701. On the other hand, if no medal is bet in step S701 or the start lever 71 is not operated in step S702, the process returns to step S701.

  Next, each process of step S703, step S705 to step S707 in the normal process will be described. Note that the abnormality determination process in step S704 will be described after describing the processes in steps S703, S705 to S707 in order to make the understanding easier.

  First, the lottery process in step S703 will be described based on the flowchart of FIG.

  In step S801, a lottery table for determining success / failure is selected based on the current setting state of the slot machine 10 and the number of medals bet. Here, in the slot machine 10, a normal game and a BB game are set as gaming states, and a lottery table is prepared corresponding to each gaming state.

  Here, the normal lottery table and the BB lottery table will be described. First, the normal lottery table will be described with reference to FIGS. 18 (a) and 19 (a). FIG. 18A is an explanatory diagram for explaining the winning probability in the normal game, and FIG. 19A is an explanatory diagram for explaining the normal lottery table.

  In the normal game, as shown in FIG. 18 (a), five types of replay, cherry, bell, watermelon, and BB are set as winning combinations. The winning probability is set according to the set value. Specifically, for the small roles such as the cherry role, the bell role, and the watermelon role, the winning probability is basically set corresponding to a predetermined range of the winning probability setting value, and the side with the larger winning probability setting value is smaller. It is set so that the winning probability is higher than the side. In the BB combination, the winning probability is set in a one-to-one correspondence with the winning probability setting value, and the winning probability is set to be higher as the winning probability setting value is larger.

  A lottery table is prepared in a one-to-one correspondence with the number of medals to bet (1 to 3), and the lottery table is selected based on the number of medals bet. For example, the winning probability of a winning combination when three bets are higher than the winning probability of winning when a single bet is three times. FIG. 18A shows the winning probability when three medals are bet.

  The winning probability as described above is realized by setting the normal lottery table corresponding to the winning probability setting value and the number of medals to bet. That is, as shown in FIG. 19 (a), the same lot of index values IV as the number of winning combinations are set in the normal lottery table. That is, as described above, in the base game, five types of winnings of replay, cherry, bell, watermelon, and BB can occur, so five index values IV of 1 to 5 are set. Each index value IV is uniquely associated with a winning combination, and a point value PV is set. Then, by selecting the normal lottery table, the winning probability becomes that when the winning probability set value in FIG. 18A is “1”. In other words, the replay winning probability is about 1/8, the cherry role winning probability is about 1/125, the bell role winning probability is about 1/15, the watermelon role winning probability is about 1/50, the BB role winning probability. Is about 1/360.

  Next, the BB lottery table will be described with reference to FIGS. 18B and 19B. FIG. 18B is an explanatory diagram for explaining the winning probability in the BB game, and FIG. 19B is an explanatory diagram for explaining the BB lottery table.

  In the BB game, as shown in FIG. 18 (b), only two types of a combination of bell and watermelon are set as winning combinations. As described above, the winning probability is set in correspondence with the winning probability setting value in the base game, but in the BB game, the winning probability is not set in correspondence with the winning probability setting value. Even so, the winning probabilities are the same. However, the winning probabilities are set in a one-to-one correspondence with the number of medals to bet (1 to 3). FIG. 18B shows the winning probability when three medals are bet.

  In the BB lottery table, as shown in FIG. 19B, an index value IV and a point value PV are set in correspondence with the bell role and the watermelon role. When the BB lottery table is selected, the winning probability is as shown in FIG. That is, the probability of winning the bell role is about 1.1 times, and the probability of winning the watermelon role is about 1/50. Here, in the BB lottery table, the bell role winning probability is much higher than that in the normal lottery table, and the bell role winning is frequently performed in each game of the BB game.

  Returning to the description of the lottery process, the index value IV is set to 1 in step S802, and a determination value DV used for determining whether or not the winning combination is determined is set in subsequent step S803. In the determination value setting process, a new determination value DV is set by adding a point value PV corresponding to the current index value IV to the current determination value DV. In the initial determination value setting process, the random number latched by the random number counter when the start lever 71 is operated is set as the current determination value DV, and this random number is a point value PV corresponding to 1 that is the current index value IV. Are added to obtain a new determination value DV.

  Thereafter, in step S804, whether or not the combination corresponding to the index value IV is determined is determined. In the determination of whether or not a winning combination is made, it is determined whether or not the determination value DV exceeds 65535. If the determining value DV exceeds 65535, the winning flag corresponding to the index value IV at that time is stored in the winning flag of the RAM 153 in step S805. Store in the area 153a. Incidentally, when the winning flag is a small role winning flag or a replay winning flag, these winning flags are cleared at the end of the game in which the corresponding winning flag is set. On the other hand, when the winning flag is the BB winning flag, the BB winning flag is cleared as one of the conditions that the combination of the BB symbols is established on the active line. That is, the BB winning flag may be valid for a plurality of games. In addition, in the success / failure determination of the winning combination after the next game carrying over the BB winning flag, the determination of whether or not the small combination or replay is made is performed, but the determination of whether or not the BB is related is not performed.

  If the determination value DV does not exceed 65535 in step S804, it means that the combination corresponding to the index value IV is lost. In such a case, 1 is added to the index value IV in step S806, and in the subsequent step S807, it is determined whether or not there is a role corresponding to the index value IV, that is, whether or not there is a role to be determined. Specifically, it is determined whether or not the index value IV added by 1 exceeds the maximum value of the index values IV set in the lottery table. If there is a winning combination to be judged, the process returns to step S803 and the winning judgment of the winning combination is continued. At this time, in step S803, the point value PV corresponding to the current index value IV is added to the determination value DV (that is, the current determination value DV) used for determining whether or not the previous winning combination is a new determination value DV. In step S804, whether or not a winning combination is determined based on the determination value DV.

  After setting the winning flag in step S805, or in the case where it is determined in step S807 that there is no winning combination, a slip table for setting a reel stop control (stop table) is set in step S808. Perform table setting processing. Here, the slip table is a table in which it is determined how much the reel is slid (rotated) and stopped after the stop switches 72 to 74 are pressed. That is, the slip table is a reaching symbol that has reached the base point position (on the lower line in the present embodiment) when the stop switches 72 to 74 are pressed, and a stop symbol that actually stops at the base point position. This is a stop data group in which the relationship is established. Thereafter, the lottery process is terminated.

  Next, the reel control processing in step S705 will be described based on the flowchart of FIG.

  In the reel control process, first, a wait process is performed in step S901. This wait process is a process of waiting without starting the reel rotation in the current game until a predetermined time (for example, 4.1 seconds) elapses from the time when the reel rotation is started in the previous game. Therefore, even if the player bets a medal and operates the start lever 71, the reels 42L, 42M, and 42R may not immediately rotate. Following the wait process, the reel rotation process in step S902 is performed to rotate the reels 42L, 42M, and 42R. Thereafter, the process proceeds to step S903, where it is determined whether or not a predetermined time has elapsed since the left reel 42L started rotating. If not, the process waits until the predetermined time elapses. If the predetermined time has elapsed, the process proceeds to step S904, where one of the stop switches 72 to 74 is pressed to generate a reel stop command, more specifically from the stop detection sensors 72a to 74a. It is determined whether an ON signal is received. That is, in the present embodiment, a period from when the left reel 42L starts to rotate until a predetermined time elapses is set as an invalid period, and the stop switches 72 to 74 are pressed in the invalid period. Also, the ON signals from the stop detection sensors 72a to 74a are invalidated. If no stop command has been issued, the process advances to step S905 to determine whether a predetermined maximum rotation time of each of the reels 42L, 42M, and 42R has elapsed. If the maximum rotation time has not elapsed, the process returns to step S904, and if the maximum rotation time has elapsed, the process proceeds to step S906 to perform a forced stop process for forcibly and sequentially stopping all the rotating reels.

  On the other hand, if any of the stop switches 72 to 74 is pressed in step S904 and a stop command is generated, the process proceeds to step S907, and reel stop processing is performed. In this reel stop process, the reel corresponding to the pressed stop switch is stopped. If a winning combination is won in the winning lottery and the winning flag is set, the reel is stored in the sliding table storage area of the RAM 153. With reference to the sliding table, control is performed so that the winning combinations are arranged on a predetermined effective line as much as possible.

  Subsequently, in step S908, it is determined whether or not the current stop command is the first stop command, that is, whether or not the stop switch has been pressed when all three reels are rotating. In the case of the first stop command, the process proceeds to step S909, and the slip table changing process is performed. In this slide table change process, for example, it is determined whether or not a combination of combinations occurs when trying to align a combination on the selected active line, and when a combination of combinations does not occur, the process proceeds to the next step as it is. When a combination of combinations occurs, the selected effective line is changed to another effective line, and after changing to a sliding table suitable for the changed effective line, the process proceeds to the next step.

  On the other hand, when the current stop command is not the first stop command in step S908, the process proceeds to step S910, whether or not the second stop command is received, that is, one of the three reels is stopped and the two reels are rotating. It is determined whether or not the stop switch has been pressed. When it is the second stop command, the process proceeds to step S911, and a stop eye determination process is performed. In this stop eye determination process, when two reels are stopped, it is determined whether or not the two are aligned with a bonus symbol such as “7” symbol. If they are not aligned, the process proceeds to the next step as it is. When sound effects are generated from the speaker 14, the process proceeds to the next step.

  Then, after the forced stop process in step S906, after the slip table change process in step S909, when the current stop command is not the second stop command in step S910, or the stop eye determination process in step S911 is performed. Thereafter, in step S912, it is determined whether or not all rotations of the left, middle, and right reels 42L, 42M, and 42R have stopped. If NO in step S912, the process returns to step S904. If YES, the payout determination process is performed in the subsequent step S913, and the reel control process ends.

  In the payout determination process, it is determined whether or not the winning combination is on the active line. If the winning combination is not aligned on the effective line, “0” is set in the payout number storage area of the RAM 153, and the winning combination is on the effective line. If they are aligned, it is determined whether or not the winning combination matches the winning combination. If they do not match, an error is displayed by the upper lamp 13 or the like and “0” is set in the payout number storage area. If they match, the number of payouts corresponding to the combinations arranged in the payout amount storage area is set.

  Next, the medal payout process in step S706 will be described based on the flowchart of FIG.

  In the medal payout process, it is first determined whether or not the payout number counted by the payout number counter in step S1001 matches the payout planned number stored in the payout planned number storage area. If the number of payouts does not match the planned payout number, it is determined in step S1002 whether the count value of the credit counter has reached the upper limit (the number of stored medals is 50). If the upper limit has not been reached, 1 is added to each of the count value of the credit counter and the number of payouts in steps S1003 and S1005. Thereafter, in step S1006, display unit change processing is performed in which the credit display unit 35 and the acquired number display unit 37 are each incremented by one.

  On the other hand, when the count value of the credit counter reaches the upper limit in step S1002, the medal payout rotating plate is driven in step S1004 to pay the medal from the hopper device 91 to the medal tray 18 through the medal discharge port 17. put out. In subsequent step S1005, 1 is added to the number of payouts according to the medal detection signal of the payout detection sensor 91a attached to the hopper device 91. After that, in step S1006, a display unit changing process for adding 1 to the number of acquired number display unit 37 is performed. After performing a display part change process in step S1006, it returns to step S1001 again. If the number of payouts and the number of payouts match in step S1001, it is determined in step S1007 whether or not the current gaming state is a BB game. If it is not a BB game, the process proceeds to step S1009, and after the payout end process is performed, this process ends. In the payout end process, the payout number storage area and the payout counter value are reset to “0”. Note that the value of the acquired number display section 37 is reset when a medal is bet to start the next game. If the current gaming state is a BB game, the number of payouts is subtracted from the count value of a remaining payout number counter described later in step S1008, and the number of remaining acquisition number display unit 36 is subtracted. . Thereafter, a payout end process is performed in step S1009, and this process ends.

  Next, the BB game process of step S707 will be described based on the flowchart of FIG.

  In the BB game process, first, in step S1101, it is determined whether or not the BB setting flag is stored in the BB setting flag storage area of the RAM 153. If the gaming state is a normal game, the BB setting flag is not stored, so a negative determination is made in step S1101 and the process proceeds to step S1102.

  In step S1102, it is determined whether the BB winning combination flag is stored in the BB winning flag storing area in the winning flag storing area 153a of the RAM 153. If the BB winning combination flag is not stored, the BB game process is terminated as it is. If the BB winning combination flag is stored, it is determined in step S1103 whether or not the combination of the BB winning symbol on the current active line has stopped. If the combination of BB winning prize symbols has not stopped, the BB game process is terminated as it is. If the combination of the BB combination winning symbol is stopped, the BB game process is terminated after executing the BB game start process in step S1104. In the BB game start process, the BB winning flag is cleared from the BB winning flag storage area of the RAM 153, and the BB setting flag is stored in the BB setting flag storing area of the RAM 153. Further, “420” is set in the remaining payout counter of the CPU 151.

  On the other hand, when the gaming state is the BB game, the BB setting flag is stored, so the process proceeds to step S1105 in step S1101. In step S1105, it is determined whether the remaining payout counter is “0”. If the remaining payout counter is not “0”, the BB game process is terminated. If the remaining payout counter is “0”, an affirmative determination is made in step S1105, and after the BB game end process is executed in step S1106, the BB game process is ended. In the BB game end process, the BB setting flag is cleared from the BB setting flag storage area of the RAM 153.

  Next, the abnormality determination process in step S704 will be described based on the flowchart in FIG.

  Prior to the description, an outline will be described. In the slot machine 10, an act of illegally trying to win a small role or a BB role using a fraudulent device is assumed. As the said fraudulent act, what is performed based on operating the start lever 71 illegally is assumed, for example. That is, in the slot machine 10, as described above, the random numbers for the lottery are appropriately updated within the range of the specific upper limit value. However, in order to assume that the winning probability of each combination is set in advance, the random numbers for the lottery are updated as appropriate. There is a certain regularity in the order of random numbers. Therefore, in the lottery random number update, the lottery random number corresponding to each combination is updated at a predetermined cycle. On the other hand, by operating the start lever 71 at a predetermined cycle using a fraudulent device, it becomes possible to repeatedly obtain random numbers for lottery corresponding to a specific combination, and winning continuously for a specific combination. It becomes possible to make it. If such fraud continues, medals will be paid out and the game will be transferred to the BB game repeatedly, resulting in a great disadvantage to the game hall. On the other hand, in the abnormality determination process, the presence or absence of abnormality is determined by comparing the number of times actually won in a predetermined number of game times and a predetermined reference value for the role to be determined, If it is determined that there is an abnormality, an abnormality process is executed.

  In the abnormality determination process, first in step S1201, the current history storage areas 153b and 153d and the winning count storage areas 153c and 153e are set in accordance with the gaming state. Specifically, it is determined whether or not the BB setting flag is stored in the BB setting flag storage area of the RAM 153. As a result, when the BB setting flag is not stored, it means that the gaming state is a normal game, and therefore the normal history storage area 153b and the normal winning count storage area 153c are set as the current target. On the other hand, when the BB setting flag is stored, it means that the gaming state is a BB game, so the BB history storage area 153d and the BB winning count storage area 153e are set as the current targets. That is, the abnormality determination process is executed according to the gaming state.

  The normal history storage area 153b and the normal winning count storage area 153c will be described with reference to FIG. 24, for convenience of explanation, FIG. 24A shows the winning flag storage area 153a, FIG. 24B shows the normal history storage area 153b, and FIG. 24C shows the normal winning count. The storage area 153c is shown.

  The normal history storage area 153b illustrated in FIG. 24B is configured by a ring buffer, and includes 100 areas of the first area RA1 to the 100th area RA100. The first area RA1 to the 100th area RA100 are configured with a data amount capable of storing and holding the lottery result of the combination in the lottery process, and in each of these areas, a lottery of each game time prior to the current game time is drawn. Result information is sequentially stored as history information (lottery result history).

  The normal history storage area 153b is provided with a pointer, and each area of the first area RA1 to the 100th area RA100 corresponds to the number of game times before the current game time based on the information of the pointer. Is identified. Specifically, the area corresponding to the pointer information is configured to be the history information before 100 gaming times. The pointer information is sequentially changed to information corresponding to each of the first area RA1 to the 100th area RA100 based on the progress of one game round. Specifically, when one game round progresses when the pointer information is information corresponding to the fourth area RA4, the pointer information is changed to information corresponding to the third area RA3. Note that, after the normal history storage area 153b is cleared, the history information is stored in descending order from the 100th area RA100.

  The normal winning count storage area 153c shown in FIG. 24C is set so that the winning count can be counted for four roles of a cherry role, a bell role, a watermelon role, and a BB role. Note that replays that do not contribute to the payout of game balls and the transition to the BB game are not subject to abnormality determination. Information on the number of winning times stored in each area of the normal winning number storing area 153c (hereinafter, this information is referred to as the cumulative number of winning times) is stored in the information stored in the winning flag storing area 153a and the normal history storing area 153b. By adding and subtracting based on the information, the information is adjusted to be information for a predetermined plurality of game times. Specifically, it is adjusted to be information for 100 game times.

  The BB history storage area 153d and the BB winning count storage area 153e will be described. The BB history storage area 153d has the same configuration as the normal history storage area 153b. On the other hand, the BB winning count storage area 153e is set so that the cumulative winning count can be counted only for the watermelon role. The cumulative number of wins is adjusted to be information for a predetermined plurality of game times by adding and subtracting based on the information stored in the win flag storage area 153a and the BB history storage area 153d. Specifically, it is adjusted to be information for 100 game times.

  Returning to the description of the abnormality determination process, in step S1202, based on the information stored in the winning flag storage area 153a and the history storage areas 153b and 153d, the winning combination of the current game round matches the winning combination before 100 gaming rounds. Determine whether you are doing it. Specifically, the current winning combination is grasped based on the winning flag storage area 153a. When the state of the winning flag storage area 153a is the state shown in FIG. 24A, the current winning combination is a bell combination.

  When one of the winning combinations is won, the winning combination before the 100 gaming times is grasped based on the area corresponding to the 100 gaming times in the history storage areas 153b and 153d. The identification of the area before 100 game times is performed based on pointers provided corresponding to the history storage areas 153b and 153d. For example, in the configuration in which the area indicated by the pointer is an area corresponding to 100 gaming times before, and the area indicated by the pointer is the 99th area RA99 in FIG. 24B, the history information before 100 gaming times is bell. It becomes a role election. In this case, if the winning flag storage area 153a is in the state shown in FIG. 24 (a), the current winning combination is the bell combination as described above. Accordingly, since the winning combination of the current game round matches the winning combination before 100 gaming rounds, an affirmative determination is made in step S1202. On the other hand, if they do not match, a negative determination is made in step S1202. Also, a negative determination is made even if no winning combination is won in step S1202.

  If a negative determination is made in step S1202, the processes shown in steps S1203 to S1211 are executed. On the other hand, if an affirmative determination is made in step S1202, the process proceeds to step S1212 without executing the processes shown in steps S1203 to S1211. That is, when an affirmative determination is made in step S1202, the adjustment process of the cumulative number of winning times, the reference value comparison determination process, and the abnormality process are not executed. As described above, the above-described processes are not executed when the winning combination this time matches the winning combination before 100 game rounds for the following reason. That is, as will be described later, in this abnormality determination process, the cumulative number of winnings corresponding to the winning combination of the current game times is incremented by 1, and the cumulative winning number corresponding to the winning combination before 100 gaming times is decremented by 1, The presence / absence of abnormality is determined based on the calculated cumulative number of winnings. In this case, if the current winning combination matches the winning combination before 100 game rounds, the cumulative winning count of the winning combination does not change, and the determination result in the reference value comparison determination process is not changed. Because.

  In step S1203, 1 is subtracted from the cumulative number of winnings corresponding to the winning combination before 100 gaming times. Specifically, the history information before 100 gaming times is grasped from the history storage areas 153b and 153d corresponding to the current gaming state. If the grasped history information is winning history information of any of the cherry role, the bell role, the watermelon role, and the BB role, 1 is subtracted from the corresponding cumulative winning number.

  In subsequent step S1204, the winning flag storage area 153a is referred to, and it is determined whether or not the winning combination to be determined in the current game round is won. However, the role to be determined differs depending on the game state, and in the normal game, it is a cherry role, a bell role, a watermelon role, and a BB role, and in the BB game, it is only a watermelon role. .

  The reason why the determination target in the BB game is only the watermelon role is as follows. In other words, as already explained, in each game of the BB game, the bell role and the watermelon role are lottery roles, and among these, the winning probability is set so that the bell role winning with a small number of medals at the time of winning a prize occurs frequently. ing. Therefore, since it is difficult to assume an act of illegally winning the bell role in the BB game, only the watermelon role is determined.

  In step S1204, first, it is determined whether or not the BB setting flag is stored in the BB setting flag storage area of the RAM 153. If the BB setting flag is not stored, is the winning combination for the base game selected? If the BB setting flag is stored, it is determined whether or not the determination target combination for the BB game is won. If the winning combination to be determined is not won, the process proceeds to step S1211 without executing the processes in steps S1205 to S1210. That is, when the winning combination is not won, the reference value comparison determination process and the abnormality process are not executed. On the other hand, if the winning combination to be determined is won, in step S1205, the cumulative number of winnings corresponding to the current winning combination is incremented by 1, and the process proceeds to step S1206.

  In step S1206, the reference value 1 and the reference value 2 are grasped based on the current winning combination, gaming state, number of bets, winning probability setting value, and monitoring state setting value. Here, the reference value will be described with reference to FIG.

  The reference value is a value for determining whether or not the cumulative number of winning times calculated this time is abnormal, and is set in correspondence with the number of games targeted for counting the cumulative number of winning times. The reference value is set in correspondence with the gaming state. That is, as described above, the combination that is the determination target in step S1204 is different according to the gaming state, and the reference value is set for the combination that is the determination target. For the normal game, reference values are set for the cherry role, the bell role, the watermelon role, and the BB role, and for the BB game, the reference value is set only for the watermelon role.

  The reference value is set in correspondence with the current winning probability of the corresponding combination. That is, the reference value is set corresponding to the number of bets. This is because the winning probability varies depending on the number of bets, as already described. Further, as shown in FIG. 25, the reference value is set in correspondence with the winning probability setting value. However, since the reference value is calculated based on the binomial distribution, it is not set in one-to-one correspondence with the winning probability setting value. Incidentally, FIG. 25 shows a reference value when three medals are bet in the base game, and corresponds to the winning probability shown in FIG.

  As the reference value, a reference value 1 and a reference value 2 having a larger value are set for each combination to be determined. Based on each of the reference value 1 and the reference value 2, it is determined whether or not the cumulative number of wins is abnormal, and abnormality processing is executed corresponding to each reference value. This will be described later.

  As shown in FIG. 25, the reference value is set in correspondence with the monitoring state setting value. As described above, the monitoring state setting value is a setting value used for setting a monitoring level, and a reference value is set corresponding to the monitoring level. Specifically, two levels of “setting 1” and “setting 2” are prepared as monitoring state setting values, and “setting 2” has a stricter monitoring level than “setting 1”. The set reference value is low.

  Returning to the description of the abnormality determination process, after grasping the current reference value 1 and the reference value 2 in step S1206, the processes of step S1207 and step S1208 are executed. That is, in step S1207, it is determined whether or not the cumulative number of winnings corresponding to the current winning combination is equal to or greater than the reference value 1. In step S1208, it is determined whether or not the cumulative number of wins corresponding to the current winning combination is equal to or greater than the reference value 2.

  If the current cumulative number of wins is greater than or equal to the reference value 1 and less than the reference value 2, an affirmative determination is made in step S1207, a negative determination is made in step S1208, and the process proceeds to step S1209. In step S1209, a first notification process as a first abnormality process is executed. Here, the first notification process is a process for alerting a game hall manager or the like as a pre-stage for prohibiting a game. Specifically, the upper error lamp 13 is turned on in a predetermined manner by transmitting a first error command to the display control device 111, and a first notification process is performed on the hall management device via the external concentration terminal board 171. A first error signal indicating the execution is transmitted. Thereafter, the process proceeds to step S1211.

  If the current cumulative number of wins is less than the reference value 1, a negative determination is made in step S1207, the first notification process is canceled in step S1210, and then the process proceeds to step S1211.

  In step S1211, the lottery result information in the current game round is stored in the history storage areas 153b and 153d in the area corresponding to 100 game rounds before, that is, in the area corresponding to the pointer information in the history storage areas 153b and 153d. Store as. Thereby, in the history storage areas 153b and 153d, the history information before 100 gaming times is erased, and the information of the lottery result in the current gaming time is stored as history information. Then, after updating the pointer information in step S1212, the abnormality determination process is terminated.

  On the other hand, if the current cumulative number of wins is greater than or equal to the reference value 2, an affirmative determination is made in step S1207 and an affirmative determination is made in step S1208, and the process proceeds to the second abnormality process in steps S1213 and S1214. In step S1213 in the second abnormality process, first, a second notification process is executed. Here, the second notification process is a process for performing control necessary for prohibiting the game thereafter. Specifically, the second error command is transmitted to the display control device 111 to turn off the various lamps, and the second notification process is executed to the hall management device via the external concentration terminal board 171. 2 Send an error signal. Thereafter, in step S1214, it is determined whether or not the monitoring reset switch 125 has been turned ON, and waits until the ON operation is performed. As a result, the normal processing in the CPU 151 of the main control device 131 does not proceed until the monitoring reset switch 125 is turned ON, and the game is prohibited. By executing the processing of step S1213 and step S1214, it is possible to prevent the act of illegally winning the small combination or the BB combination from being continued.

  Thereafter, when the monitoring reset switch 125 is turned on, an affirmative determination is made in step S1214, and after executing the processes in steps S1215 and S1216, the abnormality determination process ends. That is, in step S1215, the first notification process and the second notification process already executed are canceled, and in step S1216, the history storage areas 153b and 153d and the winning count storage areas 153c and 153e are cleared.

  By executing the abnormality determination process as described above, it is determined whether or not there is an abnormality in the cumulative number of winnings for a predetermined plurality of game times (100 game times) with respect to the combination to be determined. In particular, by adjusting the cumulative number of wins using the history storage areas 153b and 153d, the cumulative number of wins is for a predetermined number of game times that are consecutive to the game times related to the determination. Furthermore, since the history storage areas 153b and 153d and the winning count storage areas 153c and 153e are provided corresponding to the gaming states, the abnormality determination process is executed for each gaming state. Moreover, the reference value 1 and the reference value 2 are set as the determination reference values, and the first abnormality process and the second abnormality process are executed in accordance with the determination results based on the respective reference values. Furthermore, the reference value is set in accordance with the winning probability of the combination, and a reference value corresponding to the monitoring level is set.

  According to the first embodiment described in detail above, the following excellent effects are obtained.

  The RAM 153 of the main control device 131 is provided with the number-of-wins storage areas 153c and 153e so as to grasp the cumulative number of wins corresponding to the predetermined number of games for a predetermined lottery role related to the provision of a privilege to the player. Then, the abnormal process is executed when the cumulative number of winning times becomes equal to or more than the corresponding reference value. Thereby, it is possible to suppress the continued fraudulent act of winning the predetermined lottery combination by operating the lottery result of the combination using the fraudulent device. In particular, it is configured to grasp the cumulative number of wins as a cumulative determination target value for determining the presence / absence of fraud, thereby directly monitoring the fraud that manipulates the lottery result of a role using a fraudulent device. It becomes possible.

  As a reference value corresponding to each cumulative number of wins, a reference value 1 as a first upper limit reference value and a reference value 2 as a second upper limit reference value having a larger value were set. Then, the first abnormality process (first notification process in the present embodiment) is executed when the cumulative number of wins is the reference value 1 or more, and the second abnormality process is performed when the cumulative number of wins is the reference value 2 or more. Was made to run. By executing the abnormality process in a plurality of stages as described above, it is possible to suitably suppress the unauthorized act of manipulating the lottery result of the combination using the fraudulent device.

  In particular, in the present embodiment, as the first abnormality process, the specific notification is executed by the upper lamp 13 or the like to notify that the cumulative number of winning is abnormal, and as the second abnormality process, the subsequent game is performed. The prohibition game prohibition process was executed. In this case, it is possible to call attention to fraudulent behavior by executing the first abnormal processing, and it is possible to suppress continued fraudulent behavior by executing the second abnormal processing. In addition, it is possible to prevent the game prohibition process from being executed when the cumulative number of lottery winnings that are subject to determination in a normal situation in which fraud is not performed exceeds the reference value 1. be able to.

  The RAM 153 of the main control device 131 is provided with history storage areas 153b and 153d for storing the lottery result history of the winning combination, and the cumulative number of wins is grasped based on the lottery result history stored in the history storage areas 153b and 153d. did. As a result, even if it is determined whether or not the above-mentioned fraudulent act is performed in any of the game times repeatedly performed, the determination is made within the range of the predetermined number of games from the game times related to the determination. You can know the cumulative number of wins in. Therefore, it can be suitably determined whether or not there is an illegal act.

  Further, in the history storage areas 153b and 153d, the lottery result history of the combination in each game round is stored for the number of games necessary for grasping the cumulative number of wins within the range of the predetermined number of games from the closest game round. The lottery result history for the game times exceeding the necessary number of games is sequentially erased while being sequentially stored. Thereby, it can suppress that the storage capacity of the history storage areas 153b and 153d increases extremely. In addition, in the configuration in which the storage capacity of the history storage areas 153b and 153d is suppressed from being extremely increased as described above, addition and subtraction of each cumulative winning number are appropriately performed. Therefore, when determining whether or not there is an illegal act, it is possible to grasp the cumulative number of wins within a predetermined number of games from the game times related to the determination.

  The fact that the lottery result of the combination is the result of winning the lottery combination that is the object of determination was used as a trigger for determining whether or not there was an illegal act. Thereby, many opportunities for discovering the said fraudulent act can be provided, and it can suppress suitably that the said fraudulent act continues being performed.

  In particular, in the present embodiment, a plurality of lottery combinations to be determined are set in order to prevent the illegal act from being continued for a plurality of lottery combinations. In such a configuration, each lottery will be elected as a trigger for determining whether or not there is any fraudulent act for each lottery. Thereby, it is possible to provide a large number of triggers for determining whether or not there is an illegal act for each of the lotteries.

  Further, in the configuration in which a plurality of lottery combinations to be determined are set as described above, one history storage area 153b, 153d is also used for grasping the cumulative number of wins for each lottery combination. Thereby, compared with the structure which provides a log | history storage area with respect to each lottery combination, simplification of a structure can be achieved.

  In a configuration including a normal game and a BB game as the gaming state, the cumulative number of winnings is grasped corresponding to each gaming state, and it is determined whether or not there is an abnormality corresponding to each gaming state. . By adopting such a configuration, it is possible to determine whether or not there is an abnormality in each gaming state based on a reference value set corresponding to each gaming state, and to more appropriately detect fraud. it can.

  A reference value was set corresponding to the winning probability set value. Accordingly, it is possible to determine whether or not there is an abnormality based on the reference value corresponding to each winning probability setting value, and it is possible to more appropriately detect fraud.

  Multiple levels of monitoring status set values were set, and a reference value was set corresponding to each monitoring status set value. Then, the monitoring state setting value can be changed by inserting the monitoring state setting key into the monitoring state setting key insertion hole 126. Thereby, for example, a manager of a game hall can change the monitoring level of fraud as necessary.

(Second Embodiment)
In the present embodiment, the configuration relating to the abnormality determination process is different from that of the first embodiment. Therefore, the configuration according to the following will be described in detail. In the following description, differences from the first embodiment will be described, and description of the same configuration will be basically omitted.

  In the present embodiment, unlike the first embodiment, the RAM 153 of the main controller 131 is not provided with history storage areas 153b and 153d. Instead, the RAM 153 is provided with a game number storage area. This game number storage area is provided corresponding to the game state, and specifically includes a normal game number storage area and a BB game number storage area. That is, the RAM 153 of the present embodiment stores the winning flag storage area 153a, the normal winning count storage area 153c, the normal gaming count storage area, the BB winning count storage area 153e, and the BB gaming count regarding abnormality determination processing. There is an area.

  Next, the abnormality determination process in the present embodiment will be described based on the flowchart of FIG.

  In the abnormality determination process, first, in step S1301, the current winning count storage areas 153c and 153e and the gaming count storage area are set in accordance with the gaming state. The specific processing for setting is the same as the processing in step S1201 in the first embodiment.

  In subsequent step S1302, 1 is added to the information on the number-of-games storage area corresponding to the gaming state (hereinafter referred to as the accumulated number of games). Thereafter, in step S1303, by referring to the winning flag storage area 153a, it is determined whether or not the winning combination to be determined in the current game round is won. The combination to be determined in each gaming state is the same as in the first embodiment. If the winning combination to be determined is won, in step S1304, 1 is added to the cumulative number of winnings corresponding to the current winning combination, and the flow advances to step S1305. On the other hand, if the winning combination is not won, the process proceeds to step S1305.

  In step S1305, it is determined whether or not the cumulative number of games corresponding to the gaming state is “100”. If the cumulative number of games is not “100”, the abnormality determination process is terminated as it is. When the cumulative number of games is “100”, the reference value comparison determination process and the abnormality process in steps S1306 to S1314 are executed. That is, in the abnormality determination process, unlike the first embodiment, the reference value comparison determination process or the like is not executed every time the winning combination is determined, but the reference is made at a cycle of 100 game times. A value comparison determination process or the like is executed.

  In step S1306, the reference value 1 and the reference value 2 are grasped based on the gaming state, the number of bets, the winning probability setting value, and the monitoring state setting value. Details of these reference values are as described in the first embodiment. However, in step S1306 in the normal game, unlike step S1206 in the first embodiment, the reference value 1 and the reference value 2 for all the combinations that are the determination targets are grasped.

  After grasping the current reference value 1 and reference value 2 in step S1306, the processes in steps S1307 and S1308 are executed. That is, in step S1307, it is determined whether or not the cumulative number of wins is equal to or greater than the corresponding reference value 1 for all the combinations that are the determination targets. In step S1308, it is determined whether or not the cumulative number of wins is equal to or more than the corresponding reference value 2 for all the combinations that are the determination targets.

  If any of the cumulative winning counts is greater than or equal to the corresponding reference value 1 and all cumulative winning counts are less than the corresponding reference value 2, an affirmative determination is made in step S1307. A negative determination is made in step S1308, and the process proceeds to step S1309. In step S1309, the first notification process is executed. The first notification process is as described in the first embodiment. By executing the first notification process, it is possible to alert a game hall manager or the like as a pre-stage for prohibiting the game. Thereafter, the process proceeds to step S1314.

  If all the cumulative winning counts are less than the corresponding reference value 1, a negative determination is made in step S1307, the first notification process is canceled in step S1310, and then the process proceeds to step S1314.

  On the other hand, if any of the cumulative winning counts is equal to or greater than the corresponding reference value 2, an affirmative determination is made in step S1307 and an affirmative determination is made in step S1308, and the process proceeds to step S1311. In step S1311, the second notification process is executed. The second notification process is as described in the first embodiment. Thereafter, in step S1312, it is determined whether or not the monitoring reset switch 125 has been turned ON, and waits until the ON operation is performed. As a result, the normal processing in the CPU 151 of the main control device 131 does not proceed until the monitoring reset switch 125 is turned ON, and the game is prohibited. By executing the processing of step S1311 and step S1312, it is possible to prevent the act of illegally winning the small combination or the BB combination from being continued.

  Thereafter, when the monitoring reset switch 125 is turned on, an affirmative determination is made in step S1312, the first notification process and the second notification process already executed are canceled in step S1313, and the process proceeds to step S1314.

  In step S1314, the winning count storage areas 153c and 153e and the accumulated gaming count storage area are cleared. Thereafter, the abnormality determination process ends.

  By executing the abnormality determination process as described above, it is determined whether or not there is an abnormality in the cumulative number of winnings for a predetermined plurality of game times in a predetermined plurality of game times cycle with respect to the combination to be determined. Moreover, the reference value 1 and the reference value 2 are set as the determination reference values, and the first abnormality process and the second abnormality process are executed in accordance with the determination results based on the respective reference values. Furthermore, the reference value is set in accordance with the winning probability of the combination, and a reference value corresponding to the monitoring level is set.

  According to the second embodiment described in detail above, the following excellent effects can be obtained.

  The RAM 153 of the main control device 131 is provided with the number-of-wins storage areas 153c and 153e so as to grasp the cumulative number of wins corresponding to the predetermined number of games for a predetermined lottery role related to the provision of a privilege to the player. Then, the abnormal process is executed when the cumulative number of winning times becomes equal to or more than the corresponding reference value. Thereby, it is possible to suppress the continued fraudulent act of winning the predetermined lottery combination by operating the lottery result of the combination using the fraudulent device. In particular, it is configured to grasp the cumulative number of wins as a cumulative determination target value for determining the presence / absence of fraud, thereby directly monitoring the fraud that manipulates the lottery result of a role using a fraudulent device. It becomes possible.

  A cumulative game number storage area is provided in the RAM 153 of the main control device 131, and the presence / absence of the cheating is determined for each predetermined number of games. Thereby, the opportunity for discovering the said fraudulent act can be provided reliably.

  The second embodiment has the same or similar configuration as the characteristic configuration in the first embodiment, and the effect based on this configuration is the same in the second embodiment. To play.

(Third embodiment)
In the present embodiment, the configuration relating to the abnormality determination process is different from that of the first embodiment. Therefore, the configuration according to the following will be described in detail. In the following description, differences from the first embodiment will be described, and description of the same configuration will be basically omitted.

  In the present embodiment, unlike the first embodiment, the RAM 153 of the main controller 131 is not provided with the winning count storage areas 153c and 153e. Instead, the RAM 153 has an accumulated number storage area. The accumulated number storage area is provided in correspondence with the gaming state, and specifically includes a normal accumulated number storage area and a BB accumulated number storage area. Further, the RAM 153 is provided with history storage areas 153b and 153d as in the first embodiment, but each area of the history storage areas 153b and 153d from the first area RA1 to the 100th area RA100. Stores not the history information of the lottery result but the history information (payout history) of the number of medals to be paid out. Further, the RAM 153 is provided with a winning flag storage area 153a as in the first embodiment, but is not used for abnormality determination processing. Instead, the payout amount storage area is used. That is, the RAM 153 of the present embodiment has a payout number storage area, a normal history storage area 153b, a normal cumulative number storage area, a BB history storage area 153d, and a BB cumulative number storage area for abnormality determination processing. Is provided.

  In the first embodiment, the abnormality determination process is performed at the timing between the lottery process in step S703 and the reel control process in step S705 in the normal process (FIG. 16). In this embodiment, the abnormality determination process is executed as a series of processes in the payout determination process in step S913 in the reel control process (FIG. 20). The payout determination process will be described with reference to the flowchart of FIG.

  In the payout determination process, first in step S1401, the current winning determination process is executed. In the subsequent step S1402, it is determined whether or not a winning combination has been established for any combination as a result of the winning determination process. If no winning has been established, “0” is set in the payout amount storage area of the RAM 153 in step S1403, and then the process proceeds to step S1411.

  If a winning combination is established for any of the winning combinations, it is determined in step S1404 whether or not the winning combination is consistent with the winning combination. If they match, the process proceeds directly to step S1407. If they do not match, the process advances to step S1405 to execute a winning abnormality process. In the winning abnormality processing, the upper lamp 13 is turned on in a predetermined manner by transmitting a mismatch error command to the display control device 111, and the winning abnormality processing is executed in the hall management device via the external concentrated terminal board 171. A mismatch error signal is transmitted. After that, in step S1406, it is determined whether or not the reset switch 123 has been turned ON, and waits until the ON is operated. As a result, the normal processing in the CPU 151 of the main control device 131 does not proceed until the reset switch 123 is turned ON, and the game is prohibited. Thereafter, when the reset switch 123 is turned ON, an affirmative determination is made in step S1406, and the flow proceeds to step S1407.

  In step S1407, it is determined whether or not the current winning is a re-game winning. If it is a re-game win, the replay process is executed in step S1408, and “0” is set in the payout amount storage area of the RAM 153 in step S1409, and the process proceeds to step S1411. On the other hand, if it is not a re-game win, the payout number of medals corresponding to the win is set in the payout amount storage area of the RAM 153 in step S1410, and the process proceeds to step S1411. If the current winning is a BB winning combination, “0” is set in the payout amount storage area in step S1410.

  Thereafter, an abnormality determination process is executed in step S1411, and after a determination end process is executed in step S1412, the payout determination process is ended.

  Next, the abnormality determination process in the present embodiment will be described based on the flowchart of FIG.

  In the abnormality determination process, first, in step S1501, the current history storage areas 153b and 153d and the cumulative number storage area are set according to the gaming state. The specific processing for setting is the same as the processing in step S1201 in the first embodiment.

  In subsequent step S1502, based on the information stored in the planned payout number storage area and the history storage areas 153b and 153d, the number of payouts (scheduled payout number) for the current game is calculated as the number of payouts before 100 game times. It is determined whether or not they match. Specifically, the current payout number is grasped based on the payout number storage area. If the payout number is “0”, a negative determination is made in step S1502.

  When the payout number is 1 or more, the payout number before 100 game times is grasped based on the area corresponding to 100 game times before in the history storage areas 153b and 153d. The specification of the area before 100 game times is the same as in the first embodiment. If the current payout number matches the payout number before 100 gaming times, an affirmative determination is made in step S1502. On the other hand, if they do not match, a negative determination is made in step S1502.

  If a negative determination is made in step S1502, the processes shown in steps S1503 to S1511 are executed. On the other hand, if an affirmative determination is made in step S1502, the process proceeds to step S1512 without executing the processes shown in steps S1503 to S1511. In other words, if an affirmative determination is made in step S1502, the adjustment process, the reference value comparison determination process, and the abnormality process for information stored in the accumulated number storage area (hereinafter, this information is referred to as the accumulated number) are not executed. As described above, the reason why the above processes are not executed when the number of payouts this time matches the number of payouts before 100 gaming times is as follows. That is, as will be described later, in this abnormality determination process, the current payout number is added to the cumulative number, and the payout number before 100 gaming times is subtracted from the cumulative number, and the presence / absence of abnormality is determined based on the calculated cumulative number. judge. In this case, if the current payout number matches the payout number before 100 gaming times, the cumulative number is not changed, and the determination result in the reference value comparison determination process is not changed.

  In step S1503, the payout number before 100 game rounds is subtracted from the cumulative number. Specifically, the number of payouts before 100 gaming times is grasped from the history storage areas 153b and 153d corresponding to the current gaming state. If the grasped payout number is 1 or more, the value is subtracted from the cumulative number.

  In the subsequent step S1504, it is determined whether or not the current payout number is “1” or more by referring to the payout amount storage area. When the number of payouts is “0”, the process proceeds to step S1511 without executing the processes in steps S1505 to S1510. That is, when the payout number is “0”, the reference value comparison determination process and the abnormality process are not executed. On the other hand, if the number of payouts is “1” or more, the current payout number is added to the cumulative number in step S1505, and the process proceeds to step S1506.

  In step S1506, the reference value 1 and the reference value 2 are grasped based on the gaming state, the number of bets, the winning probability setting value, and the monitoring state setting value. Here, the reference value in the present embodiment is set in correspondence with the number of games targeted for counting the cumulative number, and as in the first embodiment described above, It is set according to the probability. The reference value in the present embodiment is different from the reference value in the first embodiment, and is set as a reference value for the number of payouts. For example, in a normal game, when the winning probability setting value in FIG. 25A is “1”, the reference value 1 is “296” and the reference value 2 is “389”. Yes.

  After grasping the current reference value 1 and reference value 2 in step S1506, the processes in steps S1507 and S1508 are executed. That is, in step S1507, it is determined whether or not the cumulative number is equal to or greater than the reference value 1. In step S1508, it is determined whether the cumulative number is equal to or greater than the reference value 2.

  If the current cumulative number is greater than or equal to the reference value 1 and less than the reference value 2, an affirmative determination is made in step S1507, a negative determination is made in step S1508, and the process proceeds to step S1509. In step S1509, a first notification process is executed. The first notification process is as described in the first embodiment. Thereafter, the process proceeds to step S1511. If the current cumulative number is less than the reference value 1, a negative determination is made in step S1507, the first notification process is canceled in step S1510, and then the process proceeds to step S1511.

  In step S1511, the information on the number of payouts this time is stored as history information in an area corresponding to 100 game times before in the history storage areas 153b and 153d. As a result, in the history storage areas 153b and 153d, the number of payouts before 100 gaming times is erased, and information on the current payout number is stored as history information. Then, after updating the pointer information in step S1512, the abnormality determination process is terminated.

  On the other hand, if the current cumulative number is greater than or equal to the reference value 2, an affirmative determination is made in step S1507 and an affirmative determination is made in step S1508, and the process proceeds to step S1513. In step S1513, a second notification process is executed. The second notification process is as described in the first embodiment. Thereafter, in step S1514, it is determined whether or not the monitoring reset switch 125 has been turned ON, and the process waits until it is turned ON. As a result, the normal processing in the CPU 151 of the main control device 131 does not proceed until the monitoring reset switch 125 is turned ON, and the game is prohibited. By executing the processing of step S1513 and step S1514, it is possible to prevent the act of trying to win the small role illegally.

  Thereafter, when the monitoring reset switch 125 is turned ON, an affirmative determination is made in step S1514, and after executing the processes in steps S1515 and S1516, the abnormality determination process ends. That is, in step S1515, the first notification process and the second notification process already executed are canceled, and in step S1516, the history storage areas 153b and 153d and the cumulative number storage area are cleared.

  By executing the abnormality determination process as described above, it is determined whether or not there is an abnormality in the accumulated number of predetermined multiple game times (100 game times). In particular, since the cumulative number is adjusted using the history storage areas 153b and 153d, the cumulative number is a predetermined number of game times consecutive to the game times related to the determination. Further, since the history storage areas 153b and 153d and the accumulated number storage area are provided in correspondence with the gaming state, the abnormality determination process is executed for each gaming state. Moreover, the reference value 1 and the reference value 2 are set as the determination reference values, and the first abnormality process and the second abnormality process are executed in accordance with the determination results based on the respective reference values. Furthermore, the reference value is set in accordance with the winning probability of the combination, and a reference value corresponding to the monitoring level is set. Specifically, the reference value differs depending on the set value of the winning probability, and the larger the set value of the winning probability, the larger the reference value. Further, the reference value differs depending on the monitoring level, and the lower the monitoring level (the lower the monitoring level), the larger the reference value.

  According to the third embodiment described in detail above, the following excellent effects are produced.

  An accumulated number storage area is provided in the RAM 153 of the main control device 131 so that the accumulated number of medals for a predetermined number of games can be grasped. Then, the abnormal process is executed when the cumulative number exceeds the reference value. Accordingly, it is possible to suppress the illegal act of illegally paying out medals by operating the lottery result of the combination using the fraudulent device. In particular, by grasping the cumulative number as a cumulative determination target value for determining the presence or absence of fraud, in a configuration having a plurality of medium granting roles as a lottery role, a lottery result of a role using a fraudulent device is obtained. It is possible to collectively suppress the fraud that continues to be performed by operating and winning those medium-giving roles.

  History storage areas 153b and 153d for storing medal payout histories are provided in the RAM 153 of the main controller 131, and the cumulative number of medals is grasped based on the payout histories stored in the history storage areas 153b and 153d. As a result, even if it is determined whether or not the above-mentioned fraudulent act is performed in any of the game times repeatedly performed, the determination is made within the range of the predetermined number of games from the game times related to the determination. The cumulative number of sheets can be grasped. Therefore, it can be suitably determined whether or not there is an illegal act.

  Further, in the history storage areas 153b and 153d, medal payout histories at each game time are sequentially stored for the number of games necessary for grasping the cumulative number of games within the range of the predetermined number of games from the closest game time. At the same time, the medal payout history for the game times exceeding the required number of games is sequentially deleted. Thereby, it can suppress that the storage capacity of the history storage areas 153b and 153d increases extremely. In addition, in the configuration in which the storage capacity of the history storage areas 153b and 153d is suppressed from being extremely increased in this way, the cumulative number is added and subtracted as appropriate. Therefore, when determining the presence or absence of the fraudulent act, it is possible to grasp the cumulative number within the range of the predetermined number of games from the game times related to the determination.

  The medal payout was used as a trigger for determining the presence or absence of the fraud. Thereby, many opportunities for discovering the said fraudulent act can be provided, and it can suppress suitably that the said fraudulent act continues being performed.

  The third embodiment has the same or similar configuration as the characteristic configuration in the first embodiment, and the effects based on this configuration are the same in the third embodiment. To play.

(Other embodiments)
In addition, it is not limited to the description content of each embodiment mentioned above, For example, you may implement as follows.

  (1) Although the present invention is applied to the slot machine 10 in which two types of game states of the normal game and the BB game are set, the set game state is different from those in the above embodiments. The present invention may be applied to this. For example, the present invention may be applied to a slot machine having an RT game in which a re-game winning probability is higher than that of a normal game as a gaming state. In such a slot machine, when the cumulative number of replay wins is to be determined for fraudulent acts, it is necessary to compare the cumulative win count with a reference value and perform an abnormality determination in correspondence with the winning probability of replay. Therefore, in this configuration, it is preferable to provide the history storage areas 153b and 153d and the winning count storage areas 153c and 153d corresponding to the base game and the RT game, respectively.

  (2) In addition, as a gaming state, there is a disadvantageous gaming state in which the player's advantage level is lower than that of the base game, and a transition to the disadvantageous gaming state is a predetermined lottery (hereinafter referred to as a lottery The present invention may be applied to a slot machine that is selected as a winning combination. In such a slot machine, it is assumed that a fraudulent act that prevents the above-mentioned transition opportunity role from being won in a normal game or the like by operating a lottery result of the role using an unauthorized device. Therefore, in this configuration, it is preferable that the abnormal process is executed when the cumulative number of wins of the disadvantageous transition opportunity in the plurality of game times is equal to or less than the lower limit reference value or less than the lower limit reference value. Thereby, it can suppress that the said cheating continues being performed.

  In this configuration, as the lower limit reference value, the first lower limit reference value and the second lower limit reference value that is smaller than the first lower limit reference value are set. It is good also as a structure which performs a 1st abnormality process when it becomes, and performs a 2nd abnormality process when it becomes below a 2nd lower limit reference value. Thereby, it can suppress suitably that the said fraudulent act continues being performed.

  (3) In each of the above embodiments, the abnormality determination process is executed for each of the normal game and the BB game. However, instead of this, the abnormality determination process may be executed only for the normal game.

  (12) In each of the above-described embodiments, the monitoring state set value has two stages, but is not limited to this, and may have three or more stages.

  (13) In each of the above embodiments, the main controller 131 performs the abnormality determination process. However, this may be changed. For example, the abnormality determination process may be performed in another control device such as the display control device 111.

  (14) In each of the above-described embodiments, a privilege for paying out medals is awarded when a small role winning is established. However, the present invention is not limited to this configuration, and some privilege is granted to the player. Any configuration may be used. For example, a configuration in which prizes other than medals are paid out when a small winning combination is established. Further, in a slot machine that does not have an actual medal insertion or medal payout function and manages credits owned by a player, an increase in credited medals corresponds to provision of a privilege.

  (15) In each of the embodiments described above, a belt on which a pattern is printed is attached to the outer peripheral surface of the cylindrical skeleton member 50. However, the cylindrical skeleton member and the belt are integrally formed, and the outer peripheral surface of the belt It is good also as a structure which affixes a symbol separately. In such a case, the integrally formed outer peripheral surface corresponds to an endless belt.

  (16) In each of the above embodiments, the medal payout is not performed when the “7” symbols as the state transition symbols are aligned on the active line. However, the medal payout may be performed.

  (17) In each of the above embodiments, a slot machine having three reels arranged in parallel and having five lines as effective lines has been described. However, the present invention is not limited to this configuration. For example, five reels are arranged in parallel. Or a slot machine having seven effective lines.

  (18) The symbols of the reels 42L, 42M, and 42R are not limited to pictures, numbers, characters, and the like, but may be geometric lines or figures.
