Abstract

<P>PROBLEM TO BE SOLVED: To improve services for a game player or amusement in a game by allowing the player to select the content of a replay time according to the game player's will and skill. <P>SOLUTION: In the slot game machine, a chance for a collective winning in three kinds of replay game combinations is set. Two kinds among the three kinds of the combinations consist of special replay game combinations RP2 and RP3. Pattern dispositions are so set that drawable ranges of constitutional patterns for them are not put over another. In a replay time RT1 after a finish of a big bonus, a game improving a probability of the collective winning is executed. When the collective winning occurs, a timing of game player's stop action changes a pattern of a drawing object. When the RP 2 is won through the drawing control, the game shifts to the RT 2 in which a winning probability of a common replay game combination is greatly improved. When the RP3 is won, the game shifts to the RT3 in which a game having a winning probability of the common replay game combination lower than that in the RT 2 but higher than that in a common game can be executed by 200 times. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention includes a plurality of symbol display units capable of moving and displaying symbols, and displays the movement display of each symbol display unit so that the symbols related to the winning combination in the lottery are drawn out of a plurality of types of winning combinations. A slot machine that executes a stop control (retraction control) by limiting the number of moving pieces from the player's stop operation to a predetermined value or less, and in particular, the winning probability of the re-gamer (replay) is increased. The present invention relates to a slot machine of a type that executes a specified special game period.

  In conventional slot machines, a game period in which the winning probability of a re-gamer is set higher than usual (generally “replay” after a special game mode such as a bonus game or when a specific symbol combination is prepared). There is something that sets "time". When the re-player is established, the next game can be executed without performing the betting operation of medals, and the replay time can reduce the degree of reduction of the medals held by the player from the normal level. The player's profit can be increased by that amount.

  Furthermore, in recent years, it has been proposed to improve the game characteristics of the slot machine by using the characteristics of the re-gamer and adjust the privileges given to the player. For example, in the following Patent Document 1, two types of re-game players with different winning probabilities are set, or a game state in which the win probability of that role is increased in response to winning one of the re-game players. It is described that the game is shifted and replays occur frequently.

  Further, in Patent Document 2, a plurality of small roles with different payouts are designated as “group roles”, and when this group role is elected and there are few payouts for the small roles that are actually established, the number of times corresponding to the payout difference is obtained. In addition, it is described that an RT game with an increased probability of winning a re-gamer is performed.

  As described in Patent Document 1, some conventional slot machines are provided with a plurality of game states having different winning probabilities for re-game players. It is automatically performed according to the progress state, and is not configured so that the player can select a desired game state.

  Also, in general slot machines, by setting a replay time after the end of the big bonus, the player can play a long game with a long medal earned with the big bonus. However, such a service is not desirable for a player who does not have enough time. Further, simply increasing the probability of winning a re-playing role after the big bonus may make the game progress monotonous and reduce the player's interest in the game.

  The present invention has been made paying attention to the above-mentioned various problems. By providing the player with an opportunity to select the contents of the replay time with his own intention and skill, the player can enjoy services and games. The purpose is to increase

In the first slot machine according to the present invention, three or more re-playing roles are set, and two of these are set as special re-playing roles, and the range in which symbols relating to these special re-playing roles can be drawn The symbol arrangement in which each symbol is arranged so as not to overlap is provided in at least one symbol display unit. In addition, this slot machine has a probability of winning a collective bonus for a plurality of special replayers and a non-special replay player, and a probability of winning a single replay player, respectively. A storage means for storing a lottery table in which a high probability is set; and a first special game period in which the probability of the collective winning is switched to a value higher than normal in response to the establishment of a predetermined condition. A game that ends the first special game when a special re-gamer is established in the first special game period, and starts a second special game period in which a different number of games is set depending on the established special re-gamer Control means.
In the lottery table, for a single win for a general re-gamer, a higher value is set for the winning probability in the second special game period than the normal winning probability, and is set in the second special game period. The smaller the number of times the game is played, the higher the probability of winning the single player for the general re-gamer in the period.

  According to the above, when the transition is made from the first special game period to the second special game period, the number of games in the second special game period and the general replaying role are determined by the special replaying role established as a trigger for the transition. Probability of single winning will be different. Specifically, the smaller the number of games set in the second special game period, the higher the probability of winning a single player for the general re-gamer. How is the second special game period set? Whether it is profitable for the player varies depending on the requirements such as the subsequent establishment of the jackpot.

  Here, in the symbol arrangement of at least one symbol display portion, these symbols are arranged so that the drawable range of the symbols relating to each special re-gamer does not overlap. A special game period according to the setting can be started by performing a stop operation aiming at the retractable range of the special re-gamer symbol corresponding to the setting that is expected to be profitable.

  Note that “collective winning of (a plurality of) re-playing roles” corresponds to what is described as “group role” in the aforementioned Patent Document 2. However, in this patent document 2, there is a point of setting a symbol arrangement so that the drawable range of symbols of each small role relating to a group role does not overlap, and a point of associating each game with a special game period having different contents. Nothing is listed. Further, this Patent Document 2 uses an RT game in order to eliminate a difference in payout caused by a difference in a winning combination, and a plurality of settings with different profits for the player are set by the player himself / herself. The technical idea of selecting by game operation is not recognized at all.

In the second slot machine according to the present invention, three or more re-playing roles are set, and two of these are set as special re-playing roles, and the range in which symbols relating to these special re-playing roles can be drawn The symbol arrangement in which each symbol is arranged so as not to overlap is provided in at least one symbol display unit. This slot machine also has normal probabilities for the probability of winning three or more replaying players including the two special replaying players at once and the probability of winning only one general replaying player other than the special replaying players. And a storage means for storing a lottery table in which a probability higher than normal is set, and a first special game period in which the probability of the collective winning is switched to a value higher than normal in response to a predetermined condition being satisfied The first special game period is terminated when a special re-gamer is established in the first special game period, and the second special game period is established when one of the two special re-games is established. And a game control means for starting a third special game period when the other special re-playing combination is established.
In the lottery table, a value that is higher in the winning probability in the third special game period than the normal winning probability is set for the single winning for the general re-playing player, and the winning probability in the second special game period is set. A value higher than the winning probability in the third special game period is set, and the game control means sets the number of games in the second special game period to be smaller than the number of games in the third special game period.

  In the above, by appropriately adjusting the single winning probability of the general re-playing player, the second special game period is set to a period in which there is a high possibility that the number of medals on hand can be increased instead of the game period being short. Although the possibility of increasing the number of medals on hand is lower than that of the second special game period, the game period can be set to a period in which a game with advantageous conditions than usual can be executed for a long time. In the first special game period, the probability of collective winning of three or more types of re-game players is increased, so if any special re-game player can be established according to this collective win, the second or second 3 special game periods can be entered.

  Here, in the symbol arrangement of at least one symbol display portion, these symbols are arranged so that the drawable ranges of the symbols relating to the two special re-playing roles do not overlap. The desired special game period can be started by performing a stop operation aiming at the retractable range of the special re-gamer symbol corresponding to the special game period expected to be obtained.

  In a preferred aspect of the first and second slot machines, the symbol array of the plurality of symbol display units is configured to be any re-gamer regardless of the stop operation performed at any position in the symbol array. It is configured so that the symbol can be drawn. In addition, when the game control means wins three or more re-game players in a lottery, the symbol control unit moves so that the symbols related to the special re-game players are drawn more preferentially than the symbols related to the general re-game players. Controls the display stop timing.

  According to the above configuration, when three or more re-game players are won in a lump, any one of the re-game players can be established with certainty. In addition, when both the symbol related to the special re-game player and the symbol related to the general re-game player can be withdrawn, the first special game period ends and the other symbols will be drawn. The possibility of shifting to the special game period of is increased.

  In a more preferred embodiment, the three or more re-game players are symbol combinations that differ only in the symbols corresponding to one symbol display section, and the possible retraction range between the special re-game players for the arrangement of the different symbols. Has been adjusted to avoid duplication. In this way, if the player pays attention to the stop operation for the symbol display unit in which a different symbol is set, the player draws the symbol of the target special re-gamer and establishes the special re-gamer. be able to. Therefore, even a beginner can relatively easily perform a stop operation for selecting the contents of the special game period.

  Further, the slot machine can be provided with notifying means for notifying the player that a plurality of re-game players have been won by lottery, and notifying control means for controlling the operation of the notifying means. The notification control means is configured to operate the notification means when the collective winning is established during the first special game period.

  According to the above configuration, the player is given an opportunity to shift to another special game period because notification is performed every time three or more re-game players are won in the first special game period. Can increase your concentration.

  As for the notification control means, a lottery for selecting whether or not to be notified when the collective winning is established during the first special game period is executed, and when the lottery is won, the notification means May be configured to operate. According to this configuration, even when a collective winning is established during the first special game period, a case where notification is performed and a case where notification is not performed occur.

  According to the present invention, the player himself selects the setting of the special game period in a gaming state in which the possibility of shifting to any of a plurality of special game periods with different contents of profits given to the player is increased. Since it was made possible, it is possible to develop a game that matches the player's preference and enhance the service. In addition, since the special game period setting is changed depending on the position of the symbol arrangement in the moving display to be stopped, whether or not the player can shift to the desired special game period is determined. Depending on the timing of the stop operation, the game performance can be improved.

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. Deployed. Also, a bass output speaker 4, a control board 5, and the like are attached to the rear plate of the housing 2.

  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”.

  Above the front panel 11, a liquid crystal panel 14 for displaying images, messages and the like is provided, and speakers 15 and 15 for outputting music and sound effects are provided on both sides thereof. In addition, an operation unit 16 for executing a game is formed between the front panel 11 and the lower panel 12.

  A medal payout opening 17 and a medal tray 18 are provided below the lower panel 12. A medal payout passage (not shown) is provided on the back surface of the door portion 3. The medals released from the medal payer 6 are carried to the medal payout outlet 17 through the medal payout passage and are paid out to the medal tray 18.

  The central front panel 11 is used as an area for displaying the progress of the game, and a non-colored and transparent symbol display window 20 is formed at the center. Also, below the symbol display window 20, a numerical display 19 is provided for displaying the number of medals paid out at the time of winning a prize, the number of stored credit medals, and the like.

  The reel unit 7 is arranged at a position corresponding to the symbol display window 20, and when the door 3 is closed, the three reels 8 a, 8 b, 8 c are arranged in a row in the symbol display window 20. become. On the outer peripheral surface of each reel 8a, 8b, 8c, a symbol arrangement described later is drawn. These reels 8a, 8b, and 8c are individually driven by stepping motors 9a, 9b, and 9c, respectively, and three symbols for each reel are stopped and displayed in the symbol display window 20 when stopped.

  On the surface of the symbol display window 20, as shown in FIG. 3, three winning lines L1, L2, L3 extending along the horizontal direction so as to connect the symbol display positions P of the reels 8a, 8b, 8c. Then, two winning lines L4 and L5 extending so as to cross these winning lines L1 to L3 obliquely are set.

  Returning to FIG. 1, the operation unit 16 has a medal slot 22 for receiving medals for gaming, a start lever 23 for rotating the reels 8a, 8b, and 8c all at once, and the reels 8a, 8b, and 8c. There are provided stop buttons 24a, 24b, 24c for individually stopping, a bet button 25 for setting a bet medal to a game from a credit medal deposited in the aircraft, a settlement button 26 for settlement of the credit medal, and the like. Is done.

  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. As the number of medals bet increases, the number of activated pay lines increases and the number of medals paid out at the time of winning increases.

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, and RAMs 303 and 323, respectively. Further, the main control unit 30 is provided with a random number generator 304 for lottery processing.
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 includes a symbol arrangement table for each reel 8a, 8b, 8c shown in FIG. 7 to be described later, a lottery table in which winning probabilities (shown in FIG. 8) for various combinations are set, and the like. Is stored. The RAM 303, the winning flag upon winning lottery (for storing a selected status) and, like _F BB, FR1, FR2, FR3 that game control flag (hereinafter for storing a game state during execution Etc.), various information necessary for the progress of the game is stored.

  The main control unit 30 is connected to the start lever 23, stop buttons 24a, 24b, and 24c, the bet button 25, the settlement button 26, and the medal insertion through the relay board 29 (provided on the back surface of the door 3). An inserted medal detection sensor 27 provided in the mouth 22 is connected.

  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, and the numerical indicator 19. On the other hand, the liquid crystal panel 14 shown in FIGS. 1 and 2, the speakers 4 and 15, and various effect lamps 38 are connected to the sub-control unit 32 as a drive unit for effects.

  When the initial setting is completed, the CPU 301 starts a series of controls relating to the game based on the program in the ROM 302. In the hourly game, a lottery is executed in accordance with the operation of the start lever 23, except when the winning state of the big bonus is carried over in the previous game. Specifically, a random number is sampled from the random number generator 304, and a lottery table in the ROM 303 is collated with the random number. Further, when any winning combination is won, a winning flag corresponding to the winning combination is set.

  When a predetermined winning combination is won in the above lottery, the CPU 301 controls each reel to stop at a timing when a symbol constituting the winning combination (hereinafter referred to as “winning symbol”) is drawn into a predetermined winning line (retraction control). ). In this pull-in control, the number of frames to slide the reel for pulling in the winning symbol is set to 4 or less.

In this embodiment, three types of symbol combinations RP1, RP2 and RP3 are set as re-game players, and in the lottery, a collective win for these re-game players or a single winner for RP 1 occurs (however, RP2 and RP3 are not won alone.) Further, three types of replay times RT1, RT2, RT3 are set by switching the probability of collective winning or single winning for RP1 according to the establishment of a predetermined condition.
In addition, when three types of re-game players are won in a lottery, control is performed so that the configuration symbol of RP2 or RP3 is preferentially drawn over the configuration symbol of RP1.

FIG. 5 shows the relationship between various game modes including the above three types of replay times.
In the drawing, “BB” indicates a big bonus period. “General game” means a state in which a game other than the big bonus and replay time is executed (normal state).

  When shifting from the general game to BB, a bonus game in which the winning probability for a small role or the like is higher than usual is executed until the cumulative value of the number of paid-out medals reaches a predetermined upper limit value.

When BB ends, a first replay time RT1 is started in which the probability of both single winning and collective winning for RP1 is higher than usual. Here, when the winning of RP2 or RP3 is established, RT1 ends, and when winning RP2, the second replay time RT2 is started, and when winning RP3, the third replay time RT3 is started.
On the other hand, when 30 games have been consumed without winning any of RP2 and RP3, RT1 is ended and the game returns to the general game.

  At the second and third replay times RT2 and RT3, the collective winning probabilities of the three types of replaying players return to the normal probabilities, but the single winning probabilities for RP1 are both set higher than normal. In particular, a probability that is higher than RT3 and significantly higher than usual is set for RT2. However, while the number of games that can be executed in RT2 is 50, RT3 is set so that 200 games can be executed. When the set number of games are executed, RT2 and RT3 are terminated and the game returns to the general game.

  As shown in FIG. 8 to be described later, in RT1, RT2 and RT3, the winning probabilities for the roles other than the replaying role such as the small role and BB are set in the same manner as in the general game, and at these replay times, When the BB winning is established, the replay time is ended at that time, and the process proceeds to BB. Also, in general games and RT2 and RT3, the probability is very low (1/1000), but there are cases where three types of re-game players are won in a lump. If a prize is won, the process proceeds to RT3. However, this is not the case when winning RP2 during RT2 and winning RP3 during RT3.

  According to the above-described flow of game control, RP2 and RP3 among the three types of replaying roles function as “special replaying roles” that trigger the switching of the contents of the replay time. On the other hand, RP1 is a conventional replaying player that does not have the above functions, and functions as a “general replaying player”. Note that the number of “general replaying combinations” is not limited to one, but two or more may be set and each “general replaying combination” may be elected individually.

  FIG. 6 shows specific examples of the three types of replaying roles RP1, RP2, and RP3. In this embodiment, for the RP1 which is a general re-game player, all three constituent symbols are set to a symbol with a logo mark of “RP” (hereinafter referred to as “RP logo symbol”). On the other hand, in RP2 and RP3, which are special re-game players, the center and right end designs are RP logo designs, but the left end design is the BAR design for BAR and the heart design for RP3. Set as configuration symbol.

  FIG. 7 shows a specific example of the symbol arrangement of the reels 8a, 8b, 8c. Each reel is provided with 21 symbols, and each symbol is associated with a number (0 to 20) indicating the arrangement order. Hereinafter, this number is referred to as a symbol number.

  The ROM 302 of the main control unit 30 stores a symbol arrangement table having the contents shown in FIG. The CPU 301 sets a symbol verification counter (hereinafter referred to as “symbol counter”) for each of the reels 8a, 8b, and 8c, and the reel moves by one frame based on a drive pulse to the stepping motors 9a, 9b, and 9c. The symbol counter is counted every time.

  In this embodiment, the value of the above-mentioned symbol counter is set so as to correspond to the symbol number of the symbol at the bottom of the reel display window 20 (position of the winning line L1 shown in FIG. 3). On the other hand, when a stop operation is performed, based on the value of the symbol counter at the time of the operation, it is determined whether or not the symbol can be drawn based on the lottery result. If further pull-in is possible, the number of moving pieces necessary for the pull-in is determined, and the reel is slid and stopped by the number of moving pieces.

According to the symbol arrangement of FIG. 7, the RP logo symbols are arranged at intervals (within four frames) that can be reliably pulled in any of the reels 8a, 8b, 8c.
On the reel 8a, two BAR symbols which are constituent symbols of RP2 and two heart symbols which are constituent symbols of RP3 are arranged. In FIG. 7, different symbols are attached to the positions of these symbols for each symbol type, and symbol numbers indicating the range in which these symbols can be drawn (indicating symbols positioned on the winning line L1 during the stop operation) The same pattern as that attached to each symbol is attached.

  According to the above illustration, if a stop operation is performed when the symbol at any one of the symbol numbers 10 to 18 reaches the winning line L1, at least one of the two BAR symbols is placed in the upper, middle, and lower tiers. It can be drawn into any of the symbol display positions. For example, when the stop operation is performed when the watermelon symbol of symbol number 10 reaches the winning line L1, the "BAR" symbol of symbol number 16 is drawn into the winning line L3 by sliding four reels 8a. be able to.

  Similarly, if a stop operation is performed when a symbol at any one of the symbol numbers 0 to 7 and 20 reaches the winning line L1, at least one of the two heart symbols is placed in the upper, middle, and lower tiers. It can be drawn into any of the symbol display positions.

According to the above symbol arrangement, the BAR symbol and the heart symbol are arranged on the reel 8a so that the respective retractable ranges do not overlap.
Furthermore, in this embodiment, when a collective winning for three types of re-game players occurs, the BAR symbol that is a configuration symbol for a special game player, rather than the RP logo design for the general game player, for the reel 8a or Executes the control that draws the heart symbol first. Therefore, if the player can perform a stop operation aiming at a range in which the BAR symbol can be drawn into the reel 8a or a range in which the heart symbol can be drawn, a target special game role is established and the role is dealt with. You can move to replay time. That is, the player himself selects the content of the replay time to be executed in the game.

  FIG. 8 shows a table in which the winning probability for each combination and the expected value of the number of medals paid out per game are compared for the general game and the three types of replay times RT, RT2 and RT3 (in the lottery table in the ROM 302). Stores the “winning probability” portion in the table of FIG. The expected value is the sum of values obtained by multiplying the winning probability of each combination by the number of medals paid out when the number of medals is 3 (shown in the right column in the table).

As shown in the table of FIG. 8, the same winning probabilities are assigned to each of the small combinations of BB, bell, cherry, and watermelon in any game period.
The winning probability of RP1 is set to 1 / 7.3 (about 13.7%) in general games, but is increased to 1/3 (about 33.3%) in RT1. Further, the value is increased to 74.9% in RT2, and 40.9% in RT3, so that a value higher than that in general games and RT1 is set.

  On the other hand, the probability of winning the three types of re-playing players at once (in the column of “RP1, 2, 3” in the table) is set to 1/1000 except for RT1, and 13.7% only for RT1. Probability is set.

The expected value of the number of medals per game with the above probability setting is 1.497 for general games, 2.493 for RT1, 3.3333 for RT2, and 2.313 for RT3. . Here, since the bet number of medals is assumed to be 3, in the general game, RT1, RT3, the expected value of the number of medals held by the player decreases as the game progresses. That is, in these game modes, the medal possessed by the player tends to decrease.
However, in RT3, the degree of decrease in medals is smaller than in general games, and in RT1, the degree of decrease in medals is smaller than in RT3.

  On the other hand, in RT2, contrary to the three types of game modes, the expected value of the number of owned medals increases as the game is played. That is, the player's medal tends to increase during RT2.

  FIG. 9 is a graph showing the transition of the expected value of the number of medals held by the player based on the expected value of the number of acquired medals shown in FIG. 8 for the case of shifting from RT1 to RT2 and the case of shifting from RT1 to RT3. Shown below. Specifically, assuming that the number of medals held at the end of RT1 is 100, when returning to the normal game after executing 50 games at RT2 (indicated by a dotted line), 200 times at RT3. The relationship between the expected value of the number of held medals and the number of game executions after the end of RT1 is shown for the case of returning to the general game after executing the game (indicated by a one-dot chain line).

  As shown in FIGS. 8 and 9, in RT2 of this embodiment, although the game period is short, an increase in held medals can be expected. On the other hand, in RT3, although it is not possible to suppress a decrease in owned medals, a game with good medals can be continued for a long period of time compared to general games.

  In addition, when transitioning to RT2, the expected value of the number of owned medals increases and becomes higher than when transitioning to RT3. However, when RT2 ends and the game returns to general gaming, the expected value decreases rapidly. At a certain point in time (in this embodiment, 120th game from the end of RT1), the value is the same as the expected value when the process moves to RT3. If the game is continued even after the time when the expected value becomes the same value, the expected value in the case of shifting to RT3 becomes larger than the case of returning to the general game after shifting to RT2. This magnitude relationship between the expected values is maintained even after RT3 ends and returns to the general game.

  According to the above, from the end of RT1, up to the 120th game, RT2 is more advantageous for the player than RT3, and after 120 games, RT3 is more advantageous for the player. Therefore, assuming that the game is continued until the player wins the BB prize, when the BB prize is established by the 120th game after the end of RT1, the game moves to RT3 by moving to RT2. You can get more medals. On the other hand, when the BB winning is established after the 120th game after the end of RT1, by shifting to RT3, more medals can be obtained than when shifting to RT2.

  As described above, since the player's profit / loss state changes depending on the time when the BB winning is established, the player predicts the timing of the BB winning, and which of the RT2 and RT3 is to be selected from the prediction? The stop operation can be performed based on the determination.

In this embodiment, the player is informed in advance of the switching of the replay time due to the RP2 winning or the RP3 winning, and the characteristics of the respective replay times RT2 and RT3. When winning is made, the player is informed on the effect screen or the like that the special re-gamer can be established. Therefore, if a player who knows that an opportunity to change the replay time has been given by notification, performs a stop operation on the reel 8a aiming at the retractable range of the BAR symbol or the heart symbol according to his / her wish. It becomes possible to shift to a replay time according to the desire.
However, it is not always necessary to notify each time a collective winning is made, and whether or not to notify according to collective winning may be determined by lottery.

FIG. 10 shows the flow of the main routine executed by the main control unit 30.
The processing of this main routine is started by turning on the power to the aircraft. When the power is turned on, the RAM 303 is cleared in the first ST1 (ST is an abbreviation of “step”. The same applies hereinafter). As a result of this clearing process, the various game control flags (F _BB , FR1, FR2, FR3) are all set to an off state (value is set to 0), and a lottery table for “general game” is used. Will come to be. The number of games C is also set to an initial value of 0.

Thereafter, a medal betting process is performed, and when the start lever 23 is operated, the process proceeds from ST2 to ST3, and the number of games C is incremented.
In the next ST4, the lottery is executed based on the above-mentioned “general game” winning probability. When the lottery is completed, the reels 8a, 8b, and 8c are started in ST5, and reel stop control is executed in ST6. The control in ST6 will be described in detail later.

  When all the reels 8a, 8b, and 8c are stopped by the reel stop control, it is checked whether or not a winning is established and the contents of the established winning are checked. If a re-game is won here, both ST7 and ST8 are “YES” and the process proceeds to the RT process of ST12. Although this process will be described in detail later with reference to FIG. 12, the re-game player established during the general game is RP1 in most cases, and it is rare that a substantial process is performed in the RT process. . Therefore, when winning RP1, the process immediately returns to the main routine and proceeds to ST2. However, in the next game, ST2 is set to “YES” by operating the start lever 23 without performing the betting process of medals. Become.

  If a prize other than replay is established, ST7 is “YES” and ST8 is “NO”, and the process proceeds to ST9, and a predetermined number of medals are paid out according to the contents of the prize. Also in this case, in ST12, the substantial process is not performed, and the process returns to ST2.

Further, in the above, when the BB winning is established, the process proceeds from ST10 to ST11, the big bonus flag _FBB is turned on, and the number of games C is reset. After this, the process proceeds to the RT process of ST12. Immediately after the big bonus is started, ST201 of FIG. 12 becomes “YES” and ST202 becomes “NO”, so the process immediately returns to ST2 of the main routine. Thereafter, when the game start operation proceeds to ST4 is performed, with the on-setting of the flag F _BB, lottery with lottery table for BB is performed. Therefore, a bonus game is executed from this game.

  Even during the bonus game, after the processing of ST2 to 6, processing corresponding to the winning content is executed in accordance with winning a small role or winning a replay. RT processing is performed at the end of the game every hour, but no substantial processing is performed until the cumulative value of the number of medals paid out in the BB reaches the upper limit value.

When the cumulative value of the medal payout in BB reaches the upper limit value, ST 202 is "YES" in FIG. 12, in ST 203, the flag _{F BB} is turned off, setting the game control flag FR1 is on for RT1 instead Is done. Further, in ST204, after the game count C is cleared to zero, the process returns to the main routine. Therefore, RT1 is started from this point.
When the lottery of ST4 is executed in this RT1, the possibility that a single win for RP1 or a collective win for three types of re-game players will be increased. Further, when winning RP2 or RP3 at the time of collective winning, the game control flag corresponding to the re-playing player who won the prize is set in the RT processing of ST12 (processing by ST206 to 208 or ST209 to 211 in FIG. 12). The lottery using the lottery table corresponding to the flag is executed from the game.

Next, the detailed procedure of the reel stop control in ST6 will be described with reference to FIG.
When any one of the stop buttons 24a, 24b, 24c is operated after starting each reel 8a, 8b, 8c, ST101 becomes “YES”, and control for stopping the reel corresponding to the operated button is started.

  If the BB or small role is won in the lottery, ST102 is “YES” and the process proceeds to ST112, where control for drawing the winning symbol is executed. In FIG. 11, the winning symbol pull-in control in ST112 is not described in detail. However, if the winning symbol cannot be pulled even if the reels are slid four frames, other symbols instead of the winning symbol are selected. Will be the target of withdrawal.

  If no winning combination is won in the lottery (when all of ST102, 103, and 104 are “NO”), the process proceeds to ST113, and a symbol representing a combination of detachment (missing symbol) is drawn.

  If RP1 is won by lottery, ST103 is “YES” and the process proceeds to ST110, where control for drawing in the RP logo symbol is executed.

  If collective winning of three types of RPs has occurred in the lottery, ST104 is “YES” and the process proceeds to ST105, in which it is determined whether or not the stopped reel is the reel 8a. If this determination is also “YES”, the drawing is executed while selecting the drawing target symbols according to the stop operation as follows.

  If the stop operation is performed in a state in which the range in which the BAR symbol can be drawn is displayed in the symbol display window 20, ST106 becomes “YES” and the process proceeds to ST107, and the BAR symbol is given a predetermined prize. Pull into the line. On the other hand, when the stop operation is performed in a state where the range in which the heart symbol can be drawn is displayed, ST106 is “NO”, ST108 is “YES”, and the process proceeds to ST109, and the heart symbol is set to a predetermined value. Pull into the winning line. On the other hand, if a stop operation is performed when a range in which neither the BAR symbol nor the heart symbol can be drawn is displayed (when any of symbols of symbol numbers 8, 9, and 19 is located on the winning line L1), ST106 is performed. , ST108 becomes “NO”, and the process proceeds to ST110, and the RP logo pattern is drawn into a predetermined winning line.

  When a stop operation is performed on the reels 8b and 8c other than the reel 8a, ST105 is “NO”, the process proceeds to ST110, and a process of drawing the RP logo symbol is executed.

  As described above, every time the stop operation is performed, the control for drawing the symbol based on the lottery result is executed. When all the three reels 8a, 8b, and 8c are stopped, ST111 becomes “YES”, which is shown in FIG. Return to the main routine.

  According to the above-described symbol arrangement of FIG. 7, the RP logo symbol is surely drawn in any of the reels 8a, 8b, 8c. Therefore, in any game mode, if a single win for RP1 or a collective win for each RP occurs, it is possible to reliably win a re-game player. In particular, during the period RT1 in which the probability of general winning is increased, the possibility of winning a prize for RP2 or RP3 by pulling the BAR symbol or heart symbol is increased by the timing of the stop operation on the reel 8a.

  Next, the RT process will be described in detail with reference to FIG. However, since the processing of ST201 to ST204 has already been described, description thereof is omitted here.

  In the RT process in the game (the game during the period of RT1) after FR1 is set to ON in ST203, ST205 becomes “YES”, and the processes of ST206 to 213 are executed.

  If the RP2 is won, ST206 is “YES” and the process proceeds to ST207, where the flag FR1 is turned off and the flag FR2 is turned on instead. In the next ST204, the number of games C is set to an initial value of 0.

  If the RP3 is won during the RT1, ST209 is “YES” and the process proceeds to ST210, where the flag FR1 is turned off and the FR3 is turned on instead. In the next ST211, the game count C is set to an initial value of zero.

  In this way, when a prize for the special re-gamer is established during the period of RT1, FR1 is turned off and a game control flag corresponding to the established prize is set. As a result, RT1 ends, and the replay time (RT2 or RT3) corresponding to the winning special replay player is started. At this time, the number of games C is cleared to zero, so that the number of games after the transition to RT2 and RT3 can be grasped.

  Also, if the winning of RP2 or RP3 is not established during the period of RT1, both ST206 and 209 are “NO” and ST212 is “YES”, and the process proceeds to ST213, and the number of game executions at the present time is It is checked whether or not the upper limit of RT1 has been reached 30 times. If the number of games C is 30, ST213 is “YES”, the process proceeds to ST214, the flag FR1 is turned off, and the number of games C is cleared to zero. As a result of this processing, RT1 is ended and the process returns to "general game".

  Next, in the RT process during the RT2 period, ST215 becomes “YES”, the process proceeds to ST216, and a process of comparing the number of games C during the RT2 period with the reference value 50 is performed. If the number of games C is 50, ST216 is “YES”, the process proceeds to ST217, the flag FR2 is turned off, and the number of games C is cleared to zero. As a result, RT2 ends and the game returns to "general game".

  In the RT process during the RT3 period, ST218 becomes “YES” and the process proceeds to ST219, and a process of comparing the number of games C during the ST3 period with the reference value 200 is performed. If the number of games C is 200, ST219 is “YES”, the process proceeds to ST220, the flag FR3 is turned off, and the number of games C is cleared to zero. As a result, RT3 ends and the game returns to "general game".

  In the case of winning a prize for RP2 or RP3 in the general game, the process proceeds to ST206 through the respective determination processes of ST205, 215, and 218 (both are “NO” determination). Steps ST209 to 211 are executed. Although illustration is omitted, when RP3 is won during RT2, the same processing as ST209-211 is executed, and when RP2 is won during RT3, the same as ST206-208 is performed. Execute the process.

  Furthermore, although the description is omitted in the same manner as described above, there is a case where a prize for BB is established even during the period of RT1 to RT3. In this case, before turning on the game control flag for BB in ST11, the game control flag for replay time that is set to on is turned off to end the running replay time. Further, when the flag FR1 is turned on and the three types of re-game players are collectively won, the sub-control unit 32 is caused to perform an effect for notification using the liquid crystal panel 14, the speaker 15, and the like.

  As described above, in this embodiment, when a collective winning for each re-gamer occurs at the replay time RT1 executed after the end of the BB, which of the two types of special re-game player symbols is drawn? As a result, the profits that the player enjoys are changed by the subsequent replay time. That is, since the player's own skill is related to whether or not the desired replay time can be shifted, the game performance after the end of the BB is enhanced, and the player's expectation can be enhanced. In addition, when the player selects the replay time by predicting the timing of the BB winning because the choice of RT2 or RT3 depends on the timing of winning the next BB. In addition, the interest of the game can be enhanced in terms of whether or not the prediction is accurate.

  In both RT2 and RT3, the probability of single winning for RP1 is set higher than usual, especially during the period of RT2, the occurrence of “out of” is suppressed, and by the small role winning during that period There is a high possibility that the medal earned by the player will increase the number of medals owned by the player. In this way, when the RT2 period ends in a short time and returns to “general game”, the degree of consumption of medals thereafter increases, so the game hall side must recover the loss that occurred during RT2. Can do. In addition, by adjusting the winning probability, it is possible to make almost no influence by RT2 when looking at the profit / loss of the game hall in a relatively long period.

  In the above embodiment, two types of RP2 and RP3 are set as the special re-playing roles. However, the present invention is not limited to this, and three or more types of special re-playing roles are provided. It may be changed.

For example, in addition to the aforementioned RP2 and RP3, a third special re-gamer is set, and symbols of these three types of special re-gamer are arranged on the reel 1a so that the respective retractable ranges do not overlap. . Then, when the third special re-gamer is established, as shown in FIG. 13, the process shifts to a replay time RT4 in which a game in which the expected value of the number of owned medals hardly changes can be executed up to 85 times. According to such a setting, when the player has selected RT4 and a BB winning is achieved within the period indicated by the arrow K in the figure, more profit is obtained than when RT2 or RT3 is selected. Obtainable.
In this way, the player's defeat state changes depending on which replay time the player has selected and the time when the BB winning is established, so that the interest of the game can be enhanced.
