Description

  The present invention relates to a slot machine that performs a spinning cylinder (reel, belt, etc.) stop game using a game medium such as a medal or a pachinko ball.

In this type of slot machine, a game is played by betting a predetermined number of game media (hereinafter described in the case of using medals) during a normal game, and when winning a winning lottery, for example, a big bonus (hereinafter referred to as BB). Or a special bonus state (hereinafter referred to as RB) or the like that makes it easier to obtain medals. In the special game state, the winning probability of the small role to which the game medium is paid out is higher than usual, and BB is a bonus prize that is obtained several times more medals or the like than RB. If BB or RB is won, it is possible to shift by winning a winning combination with symbols that establish these combinations.

Conventionally, most slot machines have a so-called perfect probability system in which a bonus lottery is performed for each game. In the perfect probability method, the bonus lottery probability is always constant, the expected value does not change, the lottery is drawn with the same probability, and the bonus to be won is only the difference in size, so the game content is unified and tired There is a problem that is easy to get.
In addition, as shown in Patent Document 1 or the like, in the case of a so-called bonus accumulation type slot machine that releases a stored bonus on the basis of a predetermined release opportunity while accumulating bonus winnings as the game progresses, Because the opportunity can be changed in various ways, euphoria has increased.

Therefore, as shown in Patent Document 2 and the like, in a slot machine of a complete probability method, in addition to giving a bonus game, an art that is difficult to reduce or slightly increases an acquired medal is given, and the game is suppressed while suppressing gambling There is something that tries to diversify the contents. In the RT (replay time) state in which the probability of replay (replay) is increased and the number of medals is reduced, the ART further informs (navigates) the selected small role type and establishes the role by pressing the key. It is a gaming state that makes it easy to play.
JP 2003-290436 A Japanese Patent Laid-Open No. 2007-215772 Japanese Patent Laid-Open No. 11-178879

However, even if the ART state is given, when a game is played for a long time, as long as the full probability method is maintained, the bonus lottery is always performed with a certain probability. As a result, monotonous game play that goes back and forth in the ART state has occurred, causing a problem that the rate of attracting customers or the machine operating rate does not improve.
On the other hand, in the complete probability type slot machine, the number of bonus types can be increased and the selectivity thereof can be changed to a slot game. In this case, even if the bonus is won and notified to the player, as long as it is unclear which bonus symbol is won, it is a game in which the symbol is predicted and stopped. In Patent Document 3, the number of wasted medals and the number of wasted games are calculated based on the number of out medals and the number of safe medals until the bonus game is started after notifying that the bonus flag is established from the slot machine. It is disclosed that information is provided to a player. However, such provision of information provided services to players, but did not lead to the interest of slot games.

In view of the above problems, the object of the present invention is to eliminate the uniformity and monotonization in the slot game that predicts the winning bonus generated by the complete probability method from among a variety of bonus games, and to increase the interest. It is to provide a slot machine that can.

The first embodiment according to the present invention includes a rotating display unit (for example, reel, symbol belt) with a plurality of spinning cylinders that variably displays a plurality of symbols, and a game necessary for a player to perform a spinning game. After setting the number of bets on the medium, a lottery is performed based on the lottery probability of a predetermined lottery table with the start operation of the rotation display unit as a lottery opportunity , and a plurality of winning combinations determined in advance according to the lottery result And a winning combination determining means for determining one of the re-games, a turning stop control means for performing stop control for stopping each turning of the turning display based on a stop operation of the player, and the turning stop And a winning determination means for determining that the winning combination is established when the stop state of the symbol stopped by the control means matches the display mode of the symbol corresponding to the winning combination determined by the winning combination determining means. In the plurality of winning combinations, In addition to several types of general winning combinations, in a slot machine that includes a plurality of special winning combinations that give different special games (for example, bonus games) that are advantageous to the player after winning a prize, in which the display form of the symbols is different. The first symbol constituting a part of the display form of the symbol of the special winning combination won on condition that a predetermined notification condition is satisfied in an internal winning state where any of the plural types of special winning combinations is won A second symbol constituting a part of the display form of the symbol of the special winning combination won on condition that the notification condition is satisfied in the game after the notification of the first symbol, and the second symbol execution and winning special pay for and informing means for informing all symbols of the display mode of the special winning combination of symbols was elected on condition that the notification condition in the notification after the game is satisfied, the notification by the notification means Whether or not to grant a specific game (for example, a support game that supports the winning of a small role) related to the winning special winning combination based on the game process up to the winning of If the winning special winning combination is won before the first symbol is announced, the winning special winning combination will be awarded after the first symbol is notified but before the second symbol is notified. In the case where the contents of the specific game are made advantageous to the player and the winning special winning combination is won by the notification of the second symbol after the notification of the first symbol, all symbols after the notification of the second symbol It is more advantageous to the player for the content of the specific game than when the winning special winning combination is won before the notification of the symbol, and after the notification of the second symbol, all winning symbols are notified. When winning a role, a special winning prize will be awarded after all the symbols have been announced. It is a slot machine having specific game giving means for making the content of the specific game more advantageous to the player than when winning .

In addition, the condition that the predetermined notification condition is satisfied is set based on a predetermined notification lottery,
According to the predetermined notification condition, the winning probability of the notification lottery for a special player with a low lottery probability is high according to the type of a special game player with a different number of net increase payouts and lottery probabilities generated before the win. This slot machine is made different by making it higher than the winning probability of the notification lottery for the special game player .

According to a second aspect of the present invention, in the first aspect, a high probability of making a high-probability re-gaming state in which the winning probability of the re-game is higher than that in a normal game based on the establishment of a specific game condition. The slot machine has re-playing state control means, and the predetermined notification condition is valid in the high-probability re-playing state.

According to a third aspect of the present invention, in the first and second aspects, the specific game is a winning for notifying a player of the type when at least one of the plurality of general winning combinations is won. This is a slot machine including a role notification means.

According to a first aspect of the present invention, by the notification unit, in the internal winning state either it has won a special winning combination of said plural kinds, special was elected on condition that a predetermined notification condition is satisfied winning The first symbol constituting part of the symbol display mode of the combination is notified, and the display mode of the special winning combination symbol that is won on condition that the notification condition is satisfied in the game after the notification of the first symbol is satisfied. A player notifying the second symbol that constitutes a part, and notifying all symbols in the display mode of the symbol of the special winning combination that is won on condition that the notification condition is satisfied in the game after the notification of the second symbol A special role classification notification function for the special combination based on the progress of the game until the execution of the classification determination notification and the winning of the winning special prize winning combination by the specific game granting means. A player Determining whether to grant specific game that is advantageous, when brought into winning the special winning prize until notification of the first symbol is the notification of the second symbols are the following notification of the first symbol The content of the specific game is more advantageous to the player than when the winning special winning combination is won by the time, and the winning special winning combination is awarded until the second symbol is notified after the first symbol is notified. When the second symbol is notified, the content of the specific game is made more advantageous to the player than when the winning special winning combination is won before all symbols are notified, and after the second symbol is notified. If the winning special winning combination is won before all symbols are notified, the content of the specific game will be more advantageous to the player than when winning the winning special winning combination after notifying all symbols . , Internal winning when a special winning combination was won and a bonus flag was established Bonus game contents (whether or not to add a push support notification game during the bonus game) and / or bonus in relation to the game period from the state to the winning (bonus in), the presence or absence of notification of the winning bonus type, etc. It is possible to make a difference in the presence / absence of the later specific game or the content of the addition, and to eliminate the uniformity and monotonization in the slot game by the bonus lottery complete probability method, thereby increasing the interest.

Therefore, in the game process leading to the occurrence (winning) of the special game, the display mode type (symbol combination) of the special game is identified based on the period from the winning of the special game (number of games). In connection with the execution of the notification, for example, a game process such as whether or not the special game winning can be obtained relatively early, or whether or not to win before the specific notification of the special game type is made Since the added content (including presence / absence of addition) of the specific game, which becomes an important game point, will be advantageous to the player, even if it is won, it is necessary to align and stop the bonus symbol by so-called It is possible to further enhance the interest of slot games with

The specific game according to the present invention is, for example, a high probability replay state (hereinafter referred to as RT state) in which the winning probability of replay (hereinafter referred to as replay) is higher than that during normal game, and a small role won during the RT state. RT with a small role winning support notifying game for notifying the type (hereinafter referred to as ART state). Here, in the RT state, the frequency of occurrence of replay is increased, and medal consumption is reduced compared to the non-RT normal time, which is advantageous to the player. Furthermore, in the ART state, since it is informed that a winning small role, particularly a small role that needs to be established by winning, is notified, the chance of acquiring a small role increases, and as a result, the amount of game media acquired increases. It will be advantageous to the player. The specific game may be executed during a special game, for example, by a bonus with small role winning support notification (hereinafter referred to as a super big bonus SBB) for notifying the type of a small role won during the bonus game state. can do. Further, the normal bonus game in which the specific game is not added to the SBB is a so-called normal big bonus NBB. In the following description, a game added as the specific game is simply referred to as an additional game.
In particular, as long as there are multiple types of bonuses, the winning notification of the winning bonus symbol type itself is playable, so the bonus winning notification and / or the winning bonus symbol combination notification after the winning bonus game is over. The notification lottery probability for the game can be divided into large and small, and the notification mode based on the distributed probability can be a specific game in the present invention.
Each special game only needs to have at least a different symbol display mode, that is, a symbol combination, and the value content may be BB or RB with different medal earning amounts, or a BB or RB single form. Of course, special games having different display modes with the same bonus flag may be mixed.

According to the first aspect of the present invention, the condition that the predetermined notification condition is satisfied is set based on the winning of the predetermined notification lottery. Therefore, when the notification lottery is won, the configuration pattern to confirm notification partial or total, which to a can determine the presence or absence of the additional game was triggered, the predetermined notification condition, net increase payout number and lottery probability that occurred prior to the winning Depending on the type of the special game player with a different lot, the winning probability of the notification lottery for the special game player with a low lottery probability is made higher than the winning probability of the notification lottery for the special game player with a high lottery probability. Therefore, the relationship between the bonus games is reflected in the advantages / disadvantages of the player, and the interest can be increased across the bonuses .

The notification lottery can be executed for each game, for example, starting from the establishment of a bonus flag or the bonus winning notification. The notification time can be set, for example, when the number of games is counted starting from establishment of a bonus flag or notification of bonus winning, and a predetermined number of games have elapsed.

According to the second aspect of the present invention, the winning probability of the re-game is set to the normal game (the replay lottery probability at the normal time is set to 1 / 7.3, for example) based on the establishment of the specific game condition. .) Since there is an RT state control means for making the RT state higher (the replay lottery probability at the time of RT is set to 1 / 1.2), for example, the predetermined notification condition is valid in the RT state. For example, when a bonus is won during the RT state to be added after a predetermined bonus game, the notification can be performed to determine whether to add the additional game. That is, in the above RT example, the specific game condition is winning or winning of an RT additional bonus, and RT may be provided for each bonus type. Therefore, the player can win a winning bonus by giving a lot of RT types to be added after a predetermined bonus game, setting a long game period or a short game period to the RT state, and notifying the selected bonus type. Can be made different depending on the additional RT state, and the interest can be increased.

According to the third aspect of the invention, the specific game comprises winning combination notifying means for notifying the player of the type when at least one of the multiple types of general winning combinations is won. Based on the execution decision of the additional game, an ART state or AT state that is advantageous to the player can be given during the bonus game or after the bonus game to enhance the interest of the slot game. Although the target role of the notification may be all small roles and replays, at least a specific small role that needs to be pressed may be a main notification target.

  A signal from the operation unit 319 is input to the main control unit 301 via the interface 318. In the operation unit 319, an operation signal input by the player is transmitted to the main control unit 301 via the connection terminal unit 342. The operation unit 319 includes stop switches 212a to 212c, a bet number setting switch 208, and a start switch 211. Similarly, a signal from a medal detection sensor 320 installed in a medal sorting device (not shown) for detecting and sorting medals inserted from the medal slot 210 is also input to the main control unit 301. In response to this signal, the stored number of credits in the credit number storage unit 317 is updated. The main control unit 301 includes a winning combination determining means for determining a predetermined winning combination or replay by lottery, a reel stop control means for performing reel stop control according to a stop operation timing based on the lottery result, and a predetermined combination The control means of the slot machine A is composed of winning determination means for determining whether or not a winning operation is established at the time of winning.

  A signal from a setting change unit 321 including a key switch 326 and a setting change switch 327 provided on the main control unit board is input to the main control unit 301 via an interface 318. The main control unit receives these signals and changes the set values. A signal from the front door opening detection unit 322 including the front door opening sensor SW, the first opening angle detection sensor 352, and the second opening angle detection sensor 353 is also input to the main control unit 301 via the interface 318. Signals from the stop selection switch 328a, the adjustment selection switch 328b, and the door opening sensor 329a provided on the main controller board are also input via the interface 318.

  The main control unit 301 drives and controls the display unit 209, the reel driving unit 324, the payout device 337, the door unit opening notification unit 325, the abnormality notification lamp 326, and the like via the driver circuit 323. The display 209 displays the number of credits during the game, but the setting value is displayed in the setting change mode. In addition, the display 209 is configured so that information on an abnormality that has occurred in each part of the gaming machine is displayed as an error code. When an abnormality occurs, priority is given to the display of the number of credits and the set value. Then, it is controlled by the main controller so that the error code is displayed.

  The reel driving unit 324 includes a left reel driving unit 324a, a middle reel driving unit 324b, and a right reel driving unit 324c that are provided corresponding to the reels 206a to 206c, respectively. Each of the reel driving units 324a to 324c includes a reel driving stepping motor, which rotates the reel in accordance with the operation of the start switch, and displays predetermined symbols on the reel in accordance with the operation of the stop switch. As shown in Fig. 5, the stepping motor is driven and controlled to stop at the symbol stop positions (F11 to F13, F21 to F23, and F31 to F33) in the window 207. The door part opening notification device 325 includes an LED or the like for notifying that the door part 225 is open. By turning on the door opening alarm 325, forgetting to close the door 225 can be prevented. The abnormality notification lamp 326 includes an LED or the like for notifying a control abnormality or a gaming state abnormality occurring in the gaming machine.

  The first sub-control unit 302 is connected to the main control unit 301 via the relay board 304, receives a signal from the main control unit 301 (game start signal and lottery information related to reel start), and an effect display device Control of 203 etc. is performed. The first sub-control unit 302 includes a CPU 327 that controls the overall operation of the first sub-control unit 302, a ROM 328 that stores effect display data and the like, a RAM 329 that temporarily stores the state of the effect being executed, and the like. An effect display device 203 is connected to the first sub-control unit 302 via a driver circuit 330. The effect display device 203 receives a drive signal from the first sub-control unit 302 and displays an image on the liquid crystal. Control is performed so that frames are read sequentially. By this control, an effect display related to the lottery result of the main control unit is performed. The various effects include game effects such as a display of a winning combination, a congratulation display when a winning combination is established, a progress display during a bonus, etc. performed at the time of reel start, reel rotation, or reel stop.

In the slot machine A according to the present embodiment, the first sub-control unit 302, the driver circuit 330, and the effect display device 203, depending on one of the game effect display patterns stored in the ROM 328, according to the lottery result. An effect display control means for performing a game effect display corresponding to the lottery result is configured.

  The second sub-control unit 303 is connected to the main control unit 301 via the relay board 304 and the first sub-control unit 302, receives signals from the first sub-control unit 302, and controls speakers and lamps. It has a function to perform. The second sub-control unit 303 includes a CPU 331, a ROM 332 that stores effect data and the like, a RAM 333 that temporarily stores the state of the effect being executed, and the like. An upper speaker 204, a lower speaker 217, and an effect lamp 335 are connected to the second sub control unit 303 via a driver circuit 334, and the second sub control unit 303 drives these to perform effect control.

Next, the game control operation of the slot machine A will be described below. FIG. 8 is a flowchart showing game processing by the main control unit during normal gaming. First, in order to start a game, a betting number setting process (step S1) is performed. When the bet number is set, the operation of the start switch becomes effective. Note that the number of medals required to execute one game differs depending on the game state.
When a new medal is inserted from an ungame state in which no bet number is set, this medal is detected by the medal sensor 320. For example, in the normal game state, the number of inserted medals is automatically up to three. Is set as the bet number. When the re-game is established by the previous game, the betting number setting process is not performed because the betting number is automatically set. In cases other than the above, when the player presses the bet number setting switch 208, the number of medals operated from the credit number storage unit is subtracted, and the number of bets is set as the bet number. The remaining number of credits is displayed on the display 209. At the same time, the winning line corresponding to the number of bets is activated, and that effect is displayed on the activated line display. The bet number can be changed until the start switch is operated.

After the betting number setting process (step S1), the operation of the start switch 211 is awaited (step S2). When the start switch 211 is operated, a lottery process (step S3) and a reel rotation process (step S4) are performed. In this lottery process, random numbers generated by a random number generator included in the CPU of the main control unit are extracted at the operation timing of the start switch 211, and based on a lottery table stored in the lottery table storage unit 311 of the ROM of the main control unit. This is the main lottery process for determining whether or not the game is successful. The lottery table used in this lottery varies depending on the value stored in the set value temporary storage unit 315. The lottery result determined based on the lottery table includes a small role for paying out a predetermined number of medals, a replay that allows the next game to be executed without inserting a new game medium, and a small number of games from the next game. A bonus combination for starting a bonus game that raises the winning probability of a combination, and a miss are included. When a bonus is won, a winning bonus flag of either BB or CB is stored in the RAM of the main control unit. In accordance with each bonus combination, a symbol combination (special winning combination display mode type) to be arranged on the active line is determined (see FIG. 9 described later). In the following description, the determination of each winning combination by lottery is called “winning”, and the combination of symbols corresponding to the winning combination on a predetermined effective line is called “winning”. Hereinafter, processing by the main control unit and the sub control unit will be referred to as main processing and sub processing, respectively.

  FIG. 7 shows the details of the lottery process (step S3). A random number is acquired in response to the operation execution of the start switch 211 (step S40), and a winning combination is determined based on the acquired random number (step S41). A bonus flag is stored in the RAM when a bonus is won, and is invalidated when the player is in an internal winning state (steps S43 and S44). Similarly, when any small combination or replay is won, each flag is stored, and in the case of a loss, these combination flags are not established (steps S45 to S48).

  The reel rotation process in step S4 is a process of rotating the reels 206a to 206c by transmitting a drive signal to the reel drive unit 324. By this reel rotation processing, the stop switch operation becomes effective after the rotation speed of the reel becomes constant. Subsequently, in step S5, it is detected whether or not the stop switch 12 has been operated. And when stop operation is performed, the stop control process (step S6) which stops the reel corresponding to stop operation is performed. This stop control process refers to the reel stop table stored in the ROM 306 on the basis of the stop operation position where each reel has been stopped and the lottery result of the lottery process. This is done by stopping the rotation. The reel stop position is determined so as to be pulled in and stopped within a predetermined number of symbols, that is, four frames defined in the game rules, from the position of the stop operation timing. When there are symbols corresponding to the lottery result within 4 frames from the position of the stop operation timing, the stop control is performed so that the winning combination symbols are aligned on the active line. In particular, in the re-game stop control process, when the re-game is won not only in the normal game but also in the bonus flag carry-over state, it is preferentially drawn so that the re-game is always aligned on the active line. Control is performed. Similarly, when a bonus combination is carried over in the state where the bonus flag is carried over, priority drawing of the bonus combination is possible.

  Next, in step S7, it is determined whether or not all the reels 206a to 206c are stopped. If not stopped, the process returns to step S5 to perform stop control processing. If all the reels are stopped (step S7), it is determined in step S8 whether or not the winning symbol is on the active line. When a winning is established (step S8) and the winning combination is a small combination (step S9), the payout device 337 is driven to pay out a predetermined number of medals (step S10). On the other hand, when a re-game is established (step S11), an automatic bet number setting process for automatically resetting the bet number set in the current game as the bet number of the next game is performed in step S12. . In this case, since the number of credits is not subtracted from the credit, the next game can be played without inserting a new game medium (including the consumption of credit). Since the next game bet number setting process is automatically performed, the bet number setting process is not performed in the next game. When the bonus is won, the process proceeds to bonus game processing (step S13).

FIG. 9 shows a symbol combination (combination type Nos. 1 to 54) of a winning combination in the slot machine A and a payout table. A bonus combination of BB or CB is set by a combination of bonus symbols MB1 to MB4. The BB combination consists of a combination of bonus symbols MB4, MB4 and MB1 (combination type No. 1). The CB combination includes 47 types of CBs in which the left reel and the middle reel each include any combination of bonus symbols MB1 to MB4 and the right reel includes any combination of bonus symbols MB1 to MB3 (combination types No. 2 to 48). It is a bonus. The BB combination is a combination for shifting to the first type big bonus game state (the combination continuous action device related to the first type special combination). The CB combination is a combination for shifting the game state of the unit game to the challenge bonus game state (second type special combination). When the BB combination and the CB combination exceed 100 sheets and 50 sheets (the limit value of the net increase payout number), they end.

Role type No. 49 is a replay role RP, a role type No. 49. 50 to 53 are so-called small roles (FR1 to FR5) called fruit roles. The small roles (FR1 to FR4) are paid out in a single prize. The lottery random number range of the small roles (FR1 to FR3) is set to be able to win simultaneously, and when the small roles (FR1 to FR3) are simultaneously won, if the stop operation is performed from the left by the pull-in control when the small roles are established, The payout of 14 symbols occurs due to the overlapping stop of the symbols (such as symbol No. 18 on the right reel) on the active line. Further, when the stop operation is performed from the right, a single winning is made and seven payouts are generated. Further, when the stop operation is performed from the inside, 7 or 15 payouts are generated depending on the stop timing. Similarly, the small roles (FR1 to FR4) can be won simultaneously by lottery. When the small roles (FR1 to FR4) are simultaneously selected, if the stop operation is performed from the right by the pull-in control when the small roles are established, The payout of 14 symbols occurs due to the overlapping stop of the symbols (such as symbol No. 18 on the right reel) on the active line. Further, when the stop operation is performed from the left, a single winning is made and seven payouts are generated. Further, when the stop operation is performed from the inside, seven or fifteen payouts are generated. As mentioned above, there is a possibility of winning simultaneously for small roles (FR1 to FR4), so in the ART game given after the bonus, the stop operation order is notified according to the winning content so that the number of winnings will increase. (Navigation) At the highest setting stage, bonus lottery probabilities for the BB combination and the single CB combination are 1/1200 and 1/50, respectively. The replay probability is 1 / 7.3 and improves to 1 / 1.2 during RT. The lottery probability of small roles (FR1 to FR5) is 1/21. These lottery probabilities are stored in the lottery table storage unit 311 together with various lottery tables set for each stage of bonus. The winning random number range may be set so that a specific small combination such as cherry FR2 and a bonus combination can be drawn at the same time.

After the bonus game for the special winning combination (BB or CB), the RT state is given. In the case of the BB combination, an RT state that continues until the next bonus winning is given. In the case of each CB combination, 50 games after the bonus end are in the RT state. In the present embodiment, the bonus game is related to the game period from the internal winning state where the special winning combination is won and the bonus flag is established to the winning (bonus in) and whether or not the winning bonus type is informed. The presence / absence and number of additions of the push support notification game (so-called assist time AT) to be given in the later RT state are determined. An ART with AT added in the RT state notifies (navigates) the winning bonus or small role in the RT (replay time) state in which the probability of replay (replay) is increased and the medal loss is reduced. It becomes easier for the player to establish a winning combination by pushing the eye and the player enters an advantageous gaming state.

If no prize is won even if BB or CB is won, the process proceeds to a bonus carry-over process (steps S8, S14, S15). In other words, if the determination in step S8 is NO (non-winning), it is determined in step S14 that a bonus has been won in the lottery, but as a result of stop control, the winning line was not drawn because it was not drawn. If YES, a bonus flag carry-over process is performed in step S15. In the bonus carry-over process (step S15), a lottery such as a small role is executed as in the normal game, but a BB or CB lottery process is not performed, and a bonus prize is awarded according to the winning BB or each CB flag. The reel stop control process when the bonus flag is established is established. In other words, the bonus carry-over process is performed by storing the establishment of the bonus flag in the RAM of the main control unit. In a game in which the bonus flag is established, the number of established bonus flags is added even if the bonus is won. There is no. The memorization of the bonus flag is continued until a bonus combination is won. In the present embodiment, 48 types of bonuses (BB or CB) can be generated, and there are combinations of bonus symbols corresponding to the number of bonus types. Therefore, even if one of the bonus flags is established, the bonus carry-over process is easily continued unless the symbol combination (bonus type) is notified, except when they are coincidentally arranged.

In the bonus game of BB or CB (step S13), the random number width corresponding to the specific small role (FR1 to FR4) is changed to greatly improve the winning probability of the specific small role, and the high probability in the bonus game state is small. By switching to the role lottery table, it is in an advantageous state in which a specific small role is frequently won and the player can quickly acquire medals. That is, in the bonus game state, for example, the lottery probability values of FR1 to FR4 in the fruit role are significantly improved from those in the normal game, and are substantially 1/1. The number of payouts for one FR1 winning is also increased from 7 to 15 at normal times.

FIG. 10 shows the bonus game (step S13) process. Since the process from step S20 to step S26 is the same as the process from step S1 to step S7 of FIG. 8, the description thereof is omitted here. A lottery based on the high probability small role lottery probability table in the bonus game state is performed in response to the reel start operation. If the determination of whether all the reels are stopped (step S26) is YES, it is determined in step S27 whether a winning according to the lottery has been established on the active line. If there is no winning combination, the process returns to step S20 to play the next game. If there is a win, the winning combination is determined in step S28. If the game is replayed, an automatic betting number setting process is performed in step S30 and the process returns to step S20 to play the next game. In the case of a small role, after the payout device 337 is driven in step S29 to pay out a corresponding number of medals, it is determined in step S31 whether or not the bonus game is terminated. The end timing of this bonus game is due to the fact that the added value of the payout number here reaches a prescribed number, for example, 101 if it is BB. For this reason, every time a small combination is established, the payout number is counted in the RAM of the main control unit, and when the predetermined number is reached, the bonus game is canceled and the normal game state is restored. After the bonus game is over, an ART game in which a predetermined number of AT navigations are performed in the RT state is executed (step S32).

FIG. 11 is a diagram schematically showing an ART setting process in a normal game. In the game process (internal winning state) from when the internal winning F is made to any bonus during the normal game (P1) to the bonus winning P2, various notifications A to D related to the bonus winning are performed. As shown in (11A) of FIG. 11, these notifications include bonus winning notification A due to the establishment of the bonus flag, notification B of the first symbol (left reel symbol) constituting the bonus symbol combination, and second symbol (middle reel). Symbol B) and symbol D for all symbols. These notifications A to D are executed by lottery, but may be notified when a predetermined game has elapsed, for example, starting from the establishment of a bonus flag. The number of elapsed games may be determined by lottery without fixedly setting the execution times of the notifications A to D. Further, the notifications A to D are executed in order, but the notification A may be jumped from the notification A to the notification D by lottery. Since the player can be informed of the bonus confirmation by notification after notification B, the processing of notification A may be omitted.

FIG. 12 shows a lottery probability table for symbol notification of the winning bonus combination. The lottery probability table is stored in the ROM 328 of the first sub control unit 302. The lottery probability table is used according to the previous bonus type. When the previous bonus type is CB, the G1 probability table is used, and when it is BB, the G2 probability table is used. In the probability table G1, the notification probability is set lower overall as compared to G2. That is, after the end of the BB combination, the notification interval is performed relatively early, which is more advantageous than the end of the CB combination. For example, in the bonus winning notification A, after the completion of the BB combination, the notification processing is performed with a high probability of 7/8 after the bonus flag is established, whereas after the completion of the CB combination, the notification is performed with a low probability of 1/3. It is processed. In addition, even with the notification D of all symbols, in the case of the BB combination, the notification process is performed with a high probability of 3/4 after the notification C, whereas in the case of the CB combination, the 5 / Notification processing is performed with a probability of 8. The winning probability of the BB role is considerably lower than that of the CB role, but since the probability of the symbol notification of the winning bonus role is high, the bonus symbol confirmation notification is made relatively early, and from the player's perspective It is treated as a premier bonus that is easy to obtain a continuous bonus opportunity. The probability values in the symbol notification lottery probability table may be constant or different at the stage of setting the bonus lottery probability.

After the bonus game P4 is executed by the bonus winning P2, the game shifts to the ART game P5. The granted ART setting condition in this ART game is determined by the relationship between the bonus winning point and the execution timing of the notifications A to D (P3). (11B) of FIG. 11 shows an ART addition determination condition table. This ART addition determination condition table is stored in the ROM 328 of the first sub-control unit 302.

If the bonus-in is performed during the FA period from the bonus internal winning F to the bonus winning notification A, the state is set to a complete ART state in which the small portion navigation is notified 100% when winning. In the complete ART state, the number of RTs can reach 50 or more, especially when the BB combination is won, and in that case, it is definitely advantageous to the player. If the bonus-in is performed during the AB period from the bonus winning notification A to the first symbol notification B, the ART state is set in which the small-choice navigation is notified only 25 times. Hereinafter, when bonus-in is performed during the period of the notification BC, the period of the notification CD, and after the notification D, the maximum number of times of the small role navigation is gradually reduced to 20, 15, 10 times. Accordingly, the more advantageous the post-bonus ART state can be obtained as soon as the symbol combination of the winning combination is predicted and aligned before the notification stage proceeds after the bonus flag is established.

13 to 16 show the processing flow of notifications A to D in the sub-control unit. When the notifications A to D are executed, the effect notification is performed by the effect display and the sound effect effect by the effect display device 203. When a game start signal is received from the main side, it is confirmed whether or not a bonus flag is established (step S50). When the bonus flag is not turned on, a normal game is executed (steps S51 and S52). In the normal gaming state, a so-called “gasse effect” that displays a possibility of winning a bonus in a pseudo manner when a small role or the like is won is executed by a gasse effect lottery. In the internal winning state in which the bonus flag is established (step S51), the bonus winning notification A due to the establishment of the bonus flag, the first symbol notification B, the second symbol notification B and the all symbol notification D constituting the bonus symbol combination are sequentially performed. Executed.

First, the bonus winning notification A due to the establishment of the bonus flag is executed by an alarm notification that warns of the aim of the player's stop operation (step S53). After the bonus flag is established, a predetermined game number Cn (for example, 3 games) is counted by a game counter (not shown) and stop event information from the main side is acquired (steps S54 and S55). When Cn is reached, the tendency pattern of the player's stop operation is determined in the Cn number of games. The tendency pattern of the stop operation is determined according to the types of bonus symbols MB1 to MB4 stopped on the first reel. The bonus symbol type that has stopped most is stored as a stop operation tendency pattern at that time (step S56). At this time, if the player's operation is uneven and uneven, the last operation content is evaluated and notified. Next, an execution lottery of the notification A is performed, and the notification lottery at this time is executed based on the lottery table of FIG. That is, the lottery is made by the notification lottery probability table G1 or G2 according to the previous bonus type. When winning, an alarm notification of the stop operation pattern is given and notification of winning is confirmed, then the counter is reset and the alarm notification flag is turned on (steps S57 to S59). That is, the alarm notification by the stop operation pattern also serves as a bonus winning notification, and is not performed after the notification is made once. It should be noted that the stop operation pattern notification may be enabled at any time after the execution of the notification A.

(17B) of FIG. 17 shows a screen display example of alarm notification by the effect display device 203. In this example of the screen, as a tendency to stop the number of games Cn, it is reported that a lot of red bonus symbols MB4 ("red 7") are stopped and that the first symbol of the winning bonus is not a red symbol. When the first symbol of the winning symbol matches the symbol of the stop operation tendency, only the bonus winning is notified. If the notification A is unsuccessful, the counter is reset and the process proceeds to step S63 (steps S57, S65, S63). If the winning bonus symbol is established at this stage, the process proceeds to a bonus game process (step S63), and the ART grant in this case is set as a winning process in the FA period as shown in FIG. (17A) of FIG. 17 shows a screen display example of the bonus-in blessing notification by the effect display device 203. If no bonus is won, the process returns to step S50.

If the alarm notification completion flag is on, it is determined that notification A has ended (steps S53 and S60), and the processing proceeds to notification B execution processing shown in FIG. The notification lottery of the notification B is also executed based on the lottery table of FIG. When winning, the first symbol of the winning bonus is confirmed and notified (steps S70 to S72). After the notification, the first symbol confirmation notification flag is turned on (step S76). (17C) of FIG. 17 shows a screen display example of the notification of the confirmation of the first symbol by the effect display device 203. In this screen example, it is informed that the blue bonus symbol is the first symbol of the winning bonus. If the notification B is unsuccessful, the process proceeds to step S63 (steps S71, S63). If the winning bonus symbol is established at the notification B execution stage, an ART granting setting is made according to the winning bonus symbol and the process proceeds to bonus game processing (steps S73 to S75). In this case, the ART grant is set as a winning process in the AB period as shown in FIG. If a bonus is awarded when Notification B is unsuccessful, ART is granted for the FA period. If no bonus is won, the process returns to step S50. Although omitted in the processing, after the bonus winning, the stored contents that have been processed and are no longer necessary are reset.

If the first symbol confirmation notification flag is on, it is determined that notification B has ended (steps S53 and S61), and the processing proceeds to notification C shown in FIG. Notification lottery of notification C is also executed based on the lottery table of FIG. When winning, the second symbol of the winning bonus is confirmed and notified (steps S80 to S82). After the notification, the second symbol confirmation notification flag is turned on (step S86). The determination notification of the second symbol is also performed in the same manner as (17C) of FIG. If the notification C is unfairly selected, the process proceeds to step S63 (steps S81, S63). If a winning bonus symbol is established at the execution stage of the notification C, an ART granting setting is made in accordance with the winning bonus symbol and the process proceeds to bonus game processing (steps S83 to S85). In this case, the ART grant is set as a winning process in the BC period as shown in FIG. If a bonus is awarded when the notification C is unsuccessful, ART is granted for the AB period.

When the second symbol confirmation notification flag is on, it is determined that notification C has ended (steps S53 and S62), and the processing proceeds to notification D execution processing shown in FIG. Notification lottery of notification D is also executed based on the lottery table of FIG. When winning, all the symbol combinations of the winning bonus are confirmed and notified (steps S90 to S92). After the notification, the bonus all symbols fixed notification flag is turned on (step S96). All symbols confirmation notification is also performed in the same manner as (17D) of FIG. (17D) of FIG. 17 shows a screen display example of the bonus all symbols confirmation notification by the effect display device 203. In this screen example, it is informed that the bonus CB of the combination of red 7, blue 7 and red 7 has been won. If the notification D is unfairly selected, the process proceeds to step S63 (steps S91, S63). If a winning bonus symbol is established in the execution stage of the notification D, an ART granting setting corresponding to the winning bonus symbol is performed and the process proceeds to bonus game processing (steps S893 to S95). ART granting in this case is set as a winning process after the notice D as shown in FIG. If a bonus is awarded when Notification D is not properly selected, the ART is granted for the BC period. If no bonus is won, the process returns to step S50.

As described above, in the slot machine A, in the game process leading to the occurrence (winning) of the bonus combination BB or CB, the bonus combination BB is based on the period from the winning of the special game (the number of games). In relation to the execution of the notification that identifies the type (symbol combination) of the game, a prize is awarded depending on whether or not the special game can be won relatively early, or before the special game type is specifically notified. The game process such as whether or not becomes an important game point, and the contents of the additional game (ART) that will be advantageous to the player will change, so even if you win, so-called bonus symbols will align and stop It is possible to further enhance the interest of slot games that are necessary.

In the above embodiment, the bonus confirmation notification lottery is performed with the same probability during the normal game and during the RT state (ART state), but the notification lottery probability may be different between the RT state and the normal game. FIG. 19 shows the sub notification process when the bonus winning notification probability is different between the RT state and the normal game state. For example, in the RT game given after the BB combination, in a normal game, the notification is made with a high probability of 7/8 against the notification lottery probability of 1/12. In the RT game given to the CB combination, it is notified with a probability of 3/8 that is lower than the BB combination but larger than the normal time. The notification lottery probability may be further varied depending on the type of the CB combination.

When it is confirmed on the sub side that the bonus flag is established, it is determined whether or not it is in the RT state (steps S100 and S101). Next, a bonus lottery notification lottery is executed based on the notification lottery probability in the RT state or the normal gaming state (steps S102 to S104). At the time of winning, the bonus winning is confirmed and notified as in step S53 (steps S104 and S105). In this case, since the timing of winning confirmation notification varies depending on the grant RT after the bonus game, the expectation increases in the types of winning bonuses (BB or CB) in various types of bonuses, and the interest can be increased.

In the above embodiment, the ART grant contents are determined in relation to the execution times of the notifications A to D (after the periods FA, AB, BC, CD, D) (see (11B) in FIG. 11). You may make it determine by the game number G until a bonus winning. (18A) in FIG. 18 is awarded 100% navigation ART when a bonus is won within 3 games from the bonus flag establishment F (G <4). Similarly, the maximum number of navigations is 25, 20, 15, 10 according to the following conditions: 4 ≦ G <8, 8 ≦ G <12, 12 ≦ G <20, 20 ≦ G.

In the case of (18A) in FIG. 18, the maximum number of navigations given by the number of games G from the bonus flag establishment F gradually decreases, but the maximum number of times 50 may be given when winning by lottery. If the maximum number of times 50 is given, the probability of occurrence is extremely low, but if all the small roles are won in the RT state of 50 times, all will be navigated. That is, as shown in (18B) of FIG. 18, when a bonus winning is made within 3 games from the bonus flag establishment F (G <4), the maximum number of navigation grants is 100%, and automatically 50 Times ART will be given. Hereinafter, similarly, according to the respective conditions of 4 ≦ G <8, 8 ≦ G <12, 12 ≦ G <20, and 20 ≦ G, the maximum navigation frequency grant lottery probability (%) is 75, 40, 25, It becomes 10. For example, a lottery probability of 75% means a probability value of 3/4. In the case of the BB combination, regardless of the game G, an unlimited or upper limit of 150 ARTs is given.

As shown in FIG. 18, since the ART grant contents are determined based on the game G from the establishment of the bonus flag to the bonus-in, it is possible to provide an entertaining game such as whether or not to win a bonus early after the bonus is confirmed. Can be created. For example, if the game count display is started after the bonus winning confirmation is notified, and the possibility of obtaining the granted ART and the number of navigable times are sequentially notified in accordance with the progress of the number of games, the player's expectation can be further enhanced. it can.
Since the slot machine A has 48 types of bonus types, the confirmation notification of the winning bonus symbol type itself is game-friendly. Therefore, after the end of the winning bonus game, the notification lottery probability for the bonus winning confirmation notification and / or the winning bonus symbol combination confirmation notification is divided into large and small, and the notification mode itself based on the distributed probability is added according to the present invention. It may be a game. For example, if it is applied to the game G as a slot machine for determining and notifying a bonus symbol combination by notification lottery after the bonus flag is established, for example, G <4, 4 ≦ G <8, 8 ≦ G <12, 12 ≦ G Depending on each condition of <20, 20 ≦ G, the determined notification lottery probability (%) of the bonus symbol combination is 100, 50, 25, 15, 10. In this case, when the previous game content is reset when the power is turned on, the fixed notification lottery probability is set lower than the lowest 10%, and the bonus is won once to enable the transition to the high-accuracy notification state. It is possible to realize gameability similar to a so-called probability change state by notification of winning bonus symbol combination confirmation.
