Description

  The present invention provides an effect in which a player can guess which level is selected while selecting a level in a lottery table in which the winning probability of winning a jackpot is divided into a plurality of levels. The present invention relates to a gaming machine that executes.

  For example, a conventional slot machine is provided with a lottery table in which six levels are set for the winning probability of a big winning combination such as a big bonus. Each level is represented by a set value of “1” to “6”, and a set value selection button for selecting any set value is provided in the body. Depending on which setting value is selected by this button, the occurrence frequency of the jackpot will differ.

  The selection of the set value is performed by the game site in consideration of circumstances such as securing profits and improving service to the player, and it is desirable that the selection result of the set value be notified to the player. It has been said that this is not the case. However, in recent years, it is possible to infer the setting value selected for a player who has played a game for a certain period of time in order to improve the service to the player and balance the profits between the player and the game hall. It has been proposed to perform such a notification effect.

  For example, in Patent Document 1 below, regarding the effects of two types of flash patterns, the frequency of occurrence of one flash pattern increases as the set value increases, and the frequency of occurrence of the other flash pattern increases as the set value decreases. It is described that it is set as follows. Patent Document 2 describes that a plurality of types of effect modes are provided and control is performed so that the effect modes that do not appear in a plurality of games differ depending on the set value.

JP 2000-126371 A JP 2003-102905 A

  According to the invention described in Patent Document 1, the player can infer the selected set value depending on the ratio of the occurrence frequency of each flash pattern in a predetermined period. Further, according to the invention described in Patent Document 2, if the player knows the relationship between each set value and the effect mode that does not appear, the set value selected by executing the game for a predetermined period of time. Can be grasped with high accuracy.

As described above, according to the effects described in Patent Documents 1 and 2, if the player who analyzed the mechanism of the effects continues the game for a certain period, the level of the selected winning probability is estimated with high accuracy. be able to. This guess can be made regardless of the progress of the game.
However, the performance performed on this type of gaming machine suggests the level of winning probability of the jackpot, so the relevance between the flow of performance and the appearance of the jackpot is more interesting. Seems to be able to increase.

  This invention pays attention to the above points, and by making the level of the winning probability selected by guessing the level of the selected winning probability by the aspect of the effect appearing after the success of the jackpot and the switching of the subsequent effect, The purpose is to provide.

A gaming machine according to the present invention includes a lottery table in which the winning probability of jackpot is divided into a plurality of levels, a selection means for selecting any one of a plurality of setting values indicating each of the plurality of levels, and a lottery Control means for executing lottery using the winning probability of the level indicated by the setting value selected by the selection means in the table, and controlling the presence or absence of jackpot according to the lottery result, and a plurality of Effect mode determining means for executing a lottery (for example, an effect stage selection lottery to be described later) for determining an effect mode to be executed using a first lottery table in which selection probabilities for various effect modes are determined for each of the plurality of set values. If, after the end of the jackpot, and a demonstration execution means for executing the effect by rendering mode determined by the effect mode determining means, in which comprises. The production execution means includes a plurality of selection probabilities for the production mode switching when a predetermined condition is established under a state where the production by the production mode determined by the production mode determination unit is executed after the end of the jackpot. based on the second lottery table defining each set value in the lottery (eg, as described effect stage migration drawing using the second selection probability corresponding to the setting value selected by the selection unit in the lottery table ) And an effect mode switching means for switching the effect mode being executed to another effect mode on the condition that the lottery is won. Further, in the first lottery table, the plurality of setting values are divided into two groups according to a predetermined selection probability, and the selection probabilities for the predetermined rendering modes of the setting values belonging to one group are respectively set to the other. It is set to a value higher than the selection probability for each of the set values belonging to the set for the predetermined effect mode . In the second lottery table, even with the one of the two sets in the first lottery table, for each set value belonging to the set, different values as a selection probability of the switching of the representation embodiment is set ing.

According to the above gaming machine, for example, the jackpot winning probability is divided into four levels, and four setting values indicating these levels are combined two by two in the first lottery table, and the first and first When two lottery tables are set, two setting values that are likely to be selected are notified depending on which aspect of the effect is executed after the end of the jackpot. Furthermore, depending on whether the representation embodiment is switched to another representation embodiment, the set value of it is likely to be selected from among the above two settings are broadcast. Therefore, if the player is informed of the concept of this notification in advance, the player can narrow down the set value having a high possibility of being selected to two according to the effect mode after the end of the jackpot. Furthermore, after this, it is possible to grasp which of the two set values is highly likely to be selected depending on whether or not the effect mode is switched.

As described above, according to the present invention, after the jackpot is completed, the presentation of an aspect in which it is possible to narrow down the set value that is likely to be selected is presented, so even a player who has won a jackpot is selected. In view of the desire to confirm the set value , there is a high possibility of continuing the game in order to confirm the effect mode after the jackpot . However, there are multiple setting values that are narrowed down after the jackpot, and to determine which of them is likely to be selected, you must check whether the production mode is switched. Therefore, even after the jackpot ends, the game can be played on the same platform for a considerable period of time.

Further, according to the present invention, it is difficult to narrow down setting values that are highly likely to be selected unless the effect mode immediately after the end of the jackpot is confirmed. In particular, if the player who started the game after the production mode is switched does not confirm the selection result of the new production mode by assigning a jackpot, the set value that is likely to be selected is estimated with high accuracy. It is difficult to do. Thus, the entertainment of a gaming machine can be heightened by performing an effect highly relevant to the jackpot.

In a preferred aspect of the above gaming machine, in the first lottery table, the production mode in which a selection probability higher than the selection probability for each setting value belonging to the other set is different for each of the two sets. As such, the selection probability for each effect mode is set. In this way, the correspondence between the production mode and the two combinations of the set values is clarified, and notification that is easier to understand can be performed.

In a further preferred embodiment, also with the one of the two sets, in the second lottery table, to a set value indicating the level winning probability is high for jackpot, setting showing the level winning probability is low to jackpot A higher selection probability than the value is set. In this way, it is informed that it is highly likely that the higher winning probability is selected by switching the production mode, so the value of switching the production mode can be increased and more impact can be achieved. High notification can be performed.

  The gaming machine according to the present invention is, for example, a slot machine, but the present invention is not limited to this, and the present invention is also applicable to various gaming machines that adjust the appearance frequency using a lottery table in which the winning probability is divided into a plurality of levels. Can be applied.

According to this invention, it is possible to narrow down the set value of the winning probability that is highly likely to be selected for the lottery table by the appearance mode that appears after the end of the jackpot, and the effect mode is switched. It is possible to make the player guess which of the narrowed set values is highly likely to be selected depending on whether or not it is determined. Therefore, it is possible to execute an effect in a form highly relevant to the jackpot, and to enhance the interest. In addition, the two-stage production increases the possibility that the player who has won the jackpot will continue to play the game because he wants to confirm the winning probability setting value that is likely to be selected. It becomes easier to balance the profits of the game and the amusement hall.

1 and 2 show the configuration of a slot machine to which the present invention is applied.
The slot machine 1 of this embodiment is configured by assembling a door portion 3 to a housing 2 having a front opening. Inside the housing 2, a medal dispenser 6 having a hopper 6 a at the bottom, a power supply device 10, and the like are arranged, and further above the reel unit 7 having three reels 8 a, 8 b, 8 c.

  The door 3 is constructed by assembling synthetic resin panels 11 and 12 at the center and lower part of a metal frame, respectively. Hereinafter, the panels are referred to as “front panel 11” and “lower panel 12”.

  In a predetermined range including a portion facing the reel unit 7 of the front panel 11, a transparent region 13 having no printing layer is provided. Further, two numerical indicators 14 are provided at the lateral position of the transparent region 13. These numerical indicators 14 are used to display the number of credit medals inserted and the number of medals paid out at the time of winning a prize.

  Speakers 15 are respectively provided at the left and right positions of the frame body above the front panel 11. An operation unit 16 for executing a game is provided between the front panel 11 and the lower panel 12, and a medal payout opening 17, a medal tray 18, and the like are provided below the lower panel 12. The medals released from the medal payer 6 are guided to the medal payout outlet 17 through a medal payout passage (not shown) provided on the back surface of the door 3 and are paid out to the medal tray 18.

  The operation unit 16 includes a medal slot 19 for receiving medals for gaming, a start lever 20 for rotating the reels 8a, 8b, and 8c all at once, and an individual stop for the reels 8a, 8b, and 8c. Stop buttons 21a, 21b, and 21c, a bet button 22 for setting a bet medal to the game from a credit medal deposited in the aircraft, and the like are provided.

  If the number of medals inserted into the medal slot 22 is within three, the medals are set as bets on the game, but if the number of medals exceeds three, the excess medals are stored as credit medals. Is done. Thereafter, when three or more medals are stored, three credits can be deducted from the credit medals according to the operation of the bet button 25 and bet on the game.

A liquid crystal panel 25 is provided at a location corresponding to the transparent region 13 on the back surface of the front panel 11. In this embodiment, by adjusting the transmittance of each cell of the liquid crystal panel 25, a reel display window 26 is set at a position corresponding to the reel unit 7 as shown in FIG. 8a, 8b and 8c are transparently displayed. In addition, various effect images are displayed around the reel display window 26. Further, depending on the progress of the game, the inside of the reel display window 26 may be translucent or non-transparent, and an effect image may be displayed on the entire screen of the liquid crystal panel 13.
The player can visually recognize the reels 8 a, 8 b, 8 c and the effect images through the transparent region 13.

  The reel display window 26 is set to a size capable of displaying three symbols when each reel 8a, 8b, 8c is stopped. The reel display window 26 has a total of five winning lines 27, three in the horizontal direction and two in the diagonal direction so as to connect the stop display positions of the symbols (the winning lines 27 are And displayed as an image as appropriate). Further, behind each reel 8a, 8b, 8c, a lamp 28 (shown in FIG. 4) for illuminating the stop display position of each symbol is provided.

FIG. 4 shows an electrical configuration of the slot machine 1.
The slot machine 1 is provided with a main control unit 30 that executes control related to the progress of the game, and a sub-control unit 32 that is in charge of effect processing. These control units 30 and 32 are provided with CPUs 301 and 321, ROMs 302 and 322, RAMs 303 and 323, random number generators 304 and 324 for lottery processing, respectively.
The main control unit 30 and the sub control unit 32 are connected via the relay board 31, but only the main control unit 30 transmits data, and data from the sub control unit 32 is transmitted to the main control unit 30. Will not be sent to.

  In addition to the program, the ROM 302 of the main control unit 30 stores a symbol arrangement table for each reel 8a, 8b, 8c, a lottery table in which winning probabilities for various combinations are set. In this embodiment, a lottery table (not shown) in which winning probabilities of four levels are set is used.

  In the RAM 303, a setting value indicating which level of the lottery table is used, a winning flag when winning in the lottery (for storing the winning state), and a flag indicating that a bonus game is being played ( Hereinafter, various information necessary for advancing the game, such as “bonus flag”) and the total number of medals paid out (also referred to as the number of medals acquired), are stored.

  The main control unit 30 is provided in the operation unit 16 such as the start lever 20, the stop buttons 21a, 21b, and 21c and the bet button 22 through a relay board 29 (provided on the back surface of the door 3). Connected switches are connected. Further, an inserted medal detection sensor 23 and a set value selection button 24 provided inside the medal slot 22 are also connected to the main control unit 30 via the relay board 29.

  Further, the main control unit 30 is connected to driving units such as reel driving units 34a, 34b, 34c corresponding to the reels 8a, 8b, 8c, the medal dispenser 6, the numerical value display 14, and the reel illumination lamp 28. The On the other hand, the sub-control unit 32 is connected to the liquid crystal display unit 25, the speakers 4 and 15, various production lamps 38, and the like as production drive units.

  The four levels of the lottery table are associated with numerical values “1”, “2”, “3”, and “4” (hereinafter, these numerical values are referred to as “set values”). The higher the setting value, the higher the probability of winning a big bonus that is a big hit. Note that the winning probability for a combination other than the big bonus is set to the same value for any level.

  The set value selection button 24 is used to select one of these set values, and is provided on the back surface of the door portion 3, similarly to the relay board 29. When the machine is powered on, the CPU 301 of the main control unit 30 clears the RAM 303, reads the setting value selected by the setting value selection button 24, and stores it in the RAM 303.

  Further, the CPU 301 performs “lottery” by sampling a random number from the random number generator 304 in accordance with the operation of the start lever 20 and collating the lottery table with the random number. In this case, the lottery table is collated for the level corresponding to the set value stored in the RAM 303.

  When a predetermined winning combination is won in the above lottery, the CPU 301 executes control (retraction control) for stopping each reel 8a, 8b, 8c at the timing when the symbols constituting the winning combination are drawn into the winning line 27. Note that the number of moving frames when the reel is slid for pull-in control is set within 4 frames.

  When a big bonus is won by lottery and a big bonus winning is achieved by pull-in control, the bonus game is performed by performing the above control using a special lottery table with a higher probability of winning for a role other than the big bonus. Is executed. This bonus game is continued until the number of acquired medals reaches a predetermined reference value. Note that the lottery table in the bonus game is set not to win the big bonus, but for convenience of control, four levels are set as in the normal table.

  While performing a series of game controls, the CPU 301 appropriately transmits information (such as a lottery result, establishment of a prize, start of a game, end of a bonus game) informing the current situation to the sub-control unit 32 (hereinafter, referred to as a “game”) This data transmission may be referred to as “notification”.) When the sub-control unit 32 receives the transmission information from the main control unit 30 via the relay board 31, the sub-control unit 32 executes an effect process according to the progress of the game according to the content.

  FIG. 5 shows the flow of main effects performed in this embodiment. In any effect, a moving image of the theme unified by the effect is displayed on the liquid crystal panel 25, and sound effects and music corresponding to the moving image are output from the speakers 4 and 15.

  In this embodiment, in a normal game, one of two types of effects called “stage A” and “stage B” is selected and executed. When a prize for a big bonus (hereinafter referred to as “bonus prize”) is established during these productions and the game shifts to a bonus game, the production is also switched to “bonus production”. When the bonus game ends, the stage A or stage B effect is executed again.

Which of the above stages A and B is executed is determined by lottery every time the bonus game ends (hereinafter, this lottery is referred to as “effect stage selection lottery”).
Furthermore, when the number of game executions after the bonus game ends is 30 games or more, there is an opportunity to execute a special effect that is awarded as a “single effect”. Whether or not to perform this one-off effect is also selected depending on the effect (hereinafter, this effect is referred to as “single lottery”).

  The single effect is an effect that is performed only for one game. When the single effect is completed, the stage may return to the stage before the effect, but the effect may be switched to the other stage. Whether or not to perform this stage transition is also determined by lottery (hereinafter, this lottery is referred to as “production stage transition lottery”).

All of the three types of lottery are performed in the sub-control unit 32, and a lottery table for each lottery is also registered in the ROM 322 on the sub-control unit 32 side.
FIG. 6 shows an example of a lottery table used for effect stage selection lottery, and FIG. 7 shows an example of a lottery table used for effect stage shift lottery.

  As shown in FIGS. 6 and 7, in these lottery tables, a probability is set for each set value of “1” to “4”. Further, in the stage for selection stage selection lottery, for each set value of “1” and “3”, a probability of 10% is set for stage A and a probability of 90% is set for stage B, respectively. On the other hand, for each set value of “2” and “4”, a probability of 90% is set for stage A and a probability of 10% is set for stage B, respectively.

  Further, in the stage for drawing stage transition lottery, a probability of 10% is set for each set value of “1” and “2”, and a probability of 90% is set for each set value of “3” and “4”. The The lottery table for single lottery is not shown, but is set to win with a uniform probability (for example, 50%) regardless of the set value.

  According to the above setting, the stage A indicates that the setting value “2” or “4” is highly likely to be selected. Further, when the stage A is shifted to the stage B through a single production, it is indicated that there is a high possibility that “4” is selected from the setting values “2” and “4”.

  Further, the stage B effect indicates that there is a high possibility that the setting value “1” or “3” is selected. Further, when the stage B is shifted to the stage A through a single production, it is indicated that there is a high possibility that “3” is selected from the setting values “1” and “3”.

  Therefore, if the player is provided with information about the relationship between the stages A and B and the set values in advance and the contents suggested by the stage transition, the player can perform an aspect of the effect executed after the bonus game is over. Thus, it is possible to narrow down the set values that are likely to be selected to two. Further, when the stage effect being executed has shifted to the other stage effect through a single lottery, a setting value corresponding to the higher winning probability level is selected from the two narrowed setting values. It is possible to grasp that the possibility is high. By doing in this way, it is possible to give a privilege of presenting an effect capable of narrowing the set value to the player who has assigned the bonus game, and it is possible to enhance the interest.

  Further, in this embodiment, in the stage for selection stage selection lottery, the set values (“3” and “4”) with high win probability and the set values (“1” and “2” with low win probability). )) One by one and the same probability is set for each group, so it is advantageous for the player even if the set values that are likely to be selected by each stage A and B are narrowed down to two. It cannot be inferred whether a correct setting value is selected. For this reason, it is considered that the player has a higher tendency to continue the game until at least a single effect appears. Therefore, even if the set value of “1” or “2” is selected, it is possible for the player to continue the game for a certain period of time, and a gaming table with a low winning probability is difficult to use. It can be prevented from becoming a state.

  Furthermore, according to this embodiment, the player is informed that the stage transition may occur due to the appearance of a single-shot effect, so that the player can be notified with a strong impact and enhance the interest of the game. it can.

However, it is not always necessary to perform the one-off effect, and the effect stage shift lottery may be executed on the condition that the number of game executions after the bonus game has reached 30 games without performing the one-time lottery.
In addition, the conditions for performing the single lottery or the stage transition lottery are not limited to the number of game executions, the number of paid-out medals after the bonus game has reached a predetermined value, the winning of a specific small role has been established, etc. Various conditions can be set. In addition, after the bonus game is over, if the player pulls out some reel pull-in control and executes a “eye-pushing game” that aims to establish a small role based on the player's skill, the player succeeds. On the condition that it did, you may be made to perform the single production and the transition of the stage.

FIG. 8 shows the flow of main control executed by the main control unit 30.
This process starts when the machine is turned on. First, in ST1 (ST is an abbreviation of “step”. The same applies to the following), an initial reset of the RAM 303, a process of reading the setting content of the setting value selection button 24 and storing it in the RAM 303, etc. are executed.

  Although not shown in FIG. 8, a command for instructing clearing of the RAM 323 is also sent to the sub-control unit 32 in conjunction with ST1.

  When the initial setting process is completed in this manner, the game can be executed, and the following processes are repeatedly executed until the power switch is turned off. The following processing is common to both the normal game and the bonus game, but when the bonus flag is set to ON, a lottery table different from the normal one is used.

  In ST2, a process (bet process) for setting the number of medals bet according to the actual medal insertion or the operation of the bet button 22 is executed. In ST2 when replay is established in the previous game, the bet number set in the previous game is maintained as it is.

  Next, when the start lever 20 is operated, the process proceeds from ST3 to ST4 to notify the sub-control unit 32 that the game has started. The notification of the game start includes notification of the setting value stored in the RAM 303.

  In the next ST5, a lottery applying a level corresponding to the set value in the RAM 303 in the lottery table is executed. After the lottery, the reels 8a, 8b, 8c are started in ST6 and wait for the operation of the stop buttons 21a, 21b, 21c. When any one of the stop buttons is operated, ST7 becomes “YES” and the reel stop control of ST8 is executed. In ST8, control is performed on each reel 8a, 8b, 8c in accordance with the operation of the corresponding stop button 21a, 21b, 21c to draw a symbol corresponding to the lottery result.

  When all the reels 8a, 8b, and 8c are stopped by the reel stop control described above, it is checked in ST9 whether or not a winning is achieved. If a winning is established, the process proceeds to ST10, and a process of paying out a predetermined number of medals is executed in accordance with the contents of the winning and the betting number of medals. Further, when a bonus winning is established, ST11 is “YES”, a process of setting the bonus flag to ON (ST12), and a process of notifying the establishment of the bonus winning to the sub-control unit 32 (ST13) are executed. The

  When the bonus flag is set on, the lottery table is switched from the next game as described above, and the bonus game is executed. During the bonus game, ST14 is “YES” and the process proceeds to ST15, where it is checked whether or not the number of medals acquired in the bonus game has reached a specified value. If the number of medals acquired is smaller than the prescribed value, ST15 is “NO” and the process returns to ST2, so the bonus game is continued.

  As a result of executing the predetermined number of bonus games, if it is determined that the number of acquired medals has reached a prescribed value, the process proceeds from ST15 to ST16, and the bonus game flag is turned off. Further, in ST17, the end of the bonus game is notified to the sub-control unit, and then the process returns to ST2. With such a processing flow, the normal game is restored from the next game.

FIG. 9 shows the flow of effect processing executed by the sub-control unit 32.
This process is started after the RAM 323 is cleared upon receiving a reset signal from the main control unit 30 when the power is turned on.

  In the first ST101, stage B is unconditionally selected as the stage to be executed initially. Hereinafter, until receiving a bonus winning notification from the main control unit 30, both ST102 and 103 become “NO”, and the process proceeds to ST107 and waits for a game start notification. When the game start notification is accepted here, ST107 becomes “YES” and the process proceeds to ST108, where the game number count flag is checked. However, because the game number count flag has been turned off by the previous RAM 323 clear process. The determination in ST108 is “NO”. Therefore, in this case, the process proceeds to ST118 and the stage B effect is selected.

  Hereinafter, until the bonus winning is established by the main control on the main control unit 30 side, the stage B effect is executed according to the same flow as described above. Although not shown in FIG. 9, regardless of the stage B and other effects, any notification such as the lottery result or winning is properly received from the main control unit 30 and notified. Change the image, sound effect, etc. according to the contents.

  If there is a notification of establishment of a bonus prize from the main control unit 30 at a predetermined time, ST102 becomes “YES” and the process proceeds to ST119, and a bonus effect is selected as an effect mode, and then the process proceeds to ST107. Also in this case, in response to the game start notification, ST107 and 108 are “NO” and the process proceeds to ST118. However, since the bonus effect is selected in the previous ST119, the stage B is switched to the bonus effect. That is, the effect can be switched according to the start of the bonus game.

  Thereafter, when a bonus game end notification is received from the main control unit 30, ST103 becomes “YES” and the process proceeds to ST104. In ST104, an effect stage selection lottery is executed, and stage A or stage B is selected based on the lottery result. Further, a process for turning on the game number count flag (ST105) and a process for setting the initial value 0 to the counter c (ST106) are executed, and then the process proceeds to ST107.

  The counter c is for counting the number of game executions after the bonus game. The game count flag indicates whether or not the counter c can be updated.

  When the notification of the first game start after the end of the bonus game is received, both ST107 and 108 are “YES”, and the process proceeds to ST109 to increment the counter c. Hereinafter, until the updated c reaches 30, ST110 is “NO” and the process proceeds to ST118. Therefore, the stage selected by the stage selection lottery of ST104 is performed.

  Thereafter, when the counter c reaches 30, ST110 becomes “YES”, the process proceeds to ST111, and a single effect lottery is executed. If the lottery is lost, the process proceeds to ST118, and the stage effect being selected is continued.

  When the single lottery is won, the process proceeds from ST112 to ST113, and the stage shift lottery is executed. When it is determined that the stage is to be shifted by this lottery, the process proceeds to ST115, and the stage selection is switched to a stage different from that currently being executed. Furthermore, after turning off the game number count flag in ST116, the process proceeds to ST117 to execute a one-shot effect.

  After this, when a new game start notification is accepted and ST107 is “YES”, the determination of ST108 is “NO”, so ST109 to 112 are skipped and the process proceeds to ST118, and the previous ST115 is switched. Perform stage production.

  The counter c reaches 30 and the single effect lottery is won, but even if it is determined not to shift the stage as a result of the effect stage shift lottery, the single effect is executed. However, in this case, ST114 is “NO” and ST115 and 116 are skipped, so the game number count flag remains on. Therefore, ST108 also becomes “YES” for the next game start notification, and the updating process of the counter c and the single effect lottery are performed. Furthermore, if the single-effect production lottery is won again, the production stage transition lottery is executed.

  Therefore, even if 30 games have elapsed since the bonus game has ended, there is a possibility that a single-stage effect will be executed until the stage is changed, so that the player's expectation can be maintained. Can do.

  Thus, in this embodiment, there is a possibility that the effect stage is switched after a considerable time has passed since the bonus game ended. However, the winning level that has a high possibility of being set can be confirmed immediately after the bonus game ends. If a player is replaced after the bonus game, the stage where the new player is performing can be confirmed. It will be difficult to narrow down the winning level. Therefore, it is possible to perform an effect highly relevant to the bonus game.

  In the above embodiment, in the stage for selection stage for drawing stage (FIG. 6), the set values are combined two by two, and the probability of the same content is set for each combination. You may give a some difference to the setting value of the probability in two setting values to which it belongs. Also for the stage for effect stage shift lottery (FIG. 7), the probabilities may differ for each set value.

  Further, the classification of the winning probability of the lottery table on the main control unit 30 side is not limited to four stages, and a table divided into six levels as in the conventional case may be used. In the production stage selection lottery table in this case, for example, three types of stages correspond to combinations of setting values “1” and “4”, “2” and “5”, and “3” and “6”.
