Abstract

To provide an engaging gaming machine equipped with a bonus trigger function. [Solution] In the gaming machine, when the game is being played with a first predetermined number of several predetermined numbers, the probability of winning at least one special prize is higher than when the game is being played with a second predetermined number. The symbols include a first symbol and a second symbol that is less likely to be recognized as a special prize than the first symbol. When the game is being played with a first predetermined number, if the first special prize is won after the game ends, the predetermined symbol pattern that aligns on the predetermined line consists of the second symbol. When the game is being played with a first predetermined number and the first special prize is won, the second symbol is pulled in regardless of the timing of the stop switch operation, and the predetermined symbol pattern aligns on the predetermined line, resulting in the first special prize being won.

Description

Technical Field

[0001] The present disclosure relates to a gaming machine.

Background Art

[0002] Conventionally, gaming machines equipped with bonus roles such as RB (first special accessory) or BB (accessory continuous operation device related to the first special accessory) have been known (see Patent Document 1).

[0003] In such a gaming machine, for example, a player can select the number of medals to bet from one, two, or three.

[0004] In a conventional gaming machine, for example, the hitting probability of a bonus role is set to be different depending on the number of medals bet (hereinafter referred to as the "specified number"). For example, in the case of three bets, the bonus role may be more likely to hit than in the cases of two bets and one bet.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In recent years, gaming machines equipped with a bonus trigger function have been developed. The gaming machine equipped with this bonus trigger function is, for example, a gaming machine in which the specified number is fixed to three or two after the RB execution state or the BB execution state ends. For example, in the game after the BB execution state ends, the specified number may be fixed to two, and in the game after the RB execution state ends, the specified number may be fixed to three.

[0007] The inventor of this application has found an interesting gaming machine equipped with this bonus trigger function.

[0008] The purpose of this disclosure is to provide an engaging gaming machine equipped with a bonus trigger function. [Means for solving the problem]

[0009] This disclosure is, It features multiple rotating reels, each with a different symbol. It is possible to conduct a draw for multiple roles, including multiple types of special roles. There are several types of prescribed amounts of game value required to start the game. The aforementioned special roles that are candidates for winning are determined in accordance with each of the aforementioned specified numbers. In the game played after the execution of the special game state that is entered as a result of winning the aforementioned special role has ended, it is possible to determine the execution number, which is one of the multiple types of aforementioned prescribed numbers, as the number of bets. When the game is being played using the first of several types of predetermined numbers, the probability of winning at least one of the special roles is higher than when the game is being played using a second predetermined number different from the first predetermined number. The aforementioned symbols include a first symbol and a second symbol that is less likely to make the special role recognizable than the first symbol. When the game is progressing with the first specified number, if the first special role that triggers the continuation of the game with the first specified number after the end is achieved, the predetermined symbol pattern that aligns on the predetermined line is composed of the second symbol. When the game is progressing with the first specified number, if the first special prize is won, the second symbol is drawn in regardless of the timing of the stop switch operation, and the predetermined symbol pattern is aligned on the predetermined line, thereby awarding the first special prize. It is a gaming machine. [Effects of the Invention]

[Figure 8] This flowchart shows the process of handling a fixed number of winning combinations, including the processing of two types of Big Bonus (BB) wins. [Modes for carrying out the invention]

[0012] [First Embodiment] A slot machine 1 according to an embodiment of the gaming machine of this disclosure will be described with reference to Figures 1 to 8. Note that the embodiments described below are merely examples of this disclosure, and the embodiments of this disclosure may be modified as appropriate without altering the gist of this disclosure. Furthermore, in the following description, "connection" includes cases where the connected objects are directly connected to each other, and cases where the connected objects are indirectly connected to each other via other circuit boards or devices.

[0013] As shown in FIG. 1, the slot machine 1 of this embodiment is a rotary type gaming machine in which the quantity of game values is managed by electronic data (hereinafter referred to as "game value data") without using physically existing medals. Note that FIG. 1 shows the slot machine 1 in a front view. Hereinafter, the upper, lower, left, and right in FIG. 1 are referred to as the upper, lower, left, and right of the slot machine 1.

[0014] In this slot machine 1, unlike conventional slot machines, it is not necessary to insert physically existing medals, nor are physically existing medals paid out. And in the slot machine 1, a virtual game medium converted into electronic data is used as game value data, and the game progresses. Such a slot machine 1 is called a medal-less machine, a smart slot (registered trademark), an enclosed rotary gaming machine, etc.

[0015] Hereinafter, first, the card unit 7 connected to this slot machine 1 will be described.

[0016] <Configuration of Card Unit 7> As shown in FIG. 2, the card unit 7 is communicably connected to the slot machine 1 outside the slot machine 1.

[0017] Also, the card unit 7 can store a card 70 that stores game value data as electronic data in place of physically existing medals inside it.

[0018] Note that the details of the card unit 7 are the same as those of the card unit connected to a conventional medal-less machine, so a detailed description thereof is omitted.

[0019] <Configuration of Slot Machine 1> As described above, the slot machine 1 of this embodiment is a medalless machine that allows the game to proceed without using physical tokens. In the slot machine 1 of this embodiment, the game is played using game value data as electronic data instead of physical tokens. In the following, in addition to "game value data," the term "game value" may also be used to refer to the conventional term "tokens."

[0020] As shown in Figure 1, the slot machine 1 comprises a casing 10. A front door 100 is provided on the front of the casing 10. This front door 100 is locked while the game is in progress.

[0021] A transparent reel window 200 is provided in the center of the front door 100. Through this reel window 200, the operator can see the multiple patterns displayed on the surface of each of the multiple rotating reels 20, which will be described later.

[0022] A keyhole (not shown) is provided near the right end of the front door 100 when viewed from the front of the slot machine 1 (towards the back of the page in Figure 1). A key is inserted into the keyhole to lock or unlock the front door 100 and the housing 10.

[0023] Furthermore, since slot machine 1 is a coinless machine, there is no selector or hopper device inside the cabinet 10, and store staff do not need to replenish actual tokens during gameplay.

[0024] When store staff perform tasks such as changing settings, checking settings, or maintenance, the front door 100 and the housing 10 are unlocked, and the front door 100 becomes rotatable relative to the housing 10.

[0025] Above the reel window 200, there is an LCD screen 3 for displaying various effects during gameplay, a speaker 101 (an example of an effect device), and an illuminated section 102.

[0026] LCD screen 3 displays various animation videos (animation screens) while the player is playing.

[0027] Speaker 101 outputs predetermined background music (BGM), sound effects (SE), operation sounds, and character voices. In this embodiment, the operator can adjust (set) the volume of BGM, SE, etc. from speaker 101 using a volume adjustment function that can be set, for example, on a menu screen.

[0028] The lighting unit 102 is made up of LEDs and the like, and lights up or turns off in a predetermined pattern when, for example, a highly anticipated performance screen is displayed or a winning combination is achieved.

[0029] Below the reel window 200 are the control panel 4, the lower panel 103, and the front bottom 104. The lower panel 103 displays the title of the slot machine 1. The front bottom 104 is designed to allow the operator to place their personal belongings.

[0030] The control unit 4 includes multiple stop switches 40 (40a, 40b, 40c), a bet switch 41, a lever 42, a digital counter 43, a counting button 44, a cancel button 45, a performance button 46, and a confirmation key 47.

[0031] Sensors are provided near each switch on the control unit 4 to detect the player's actions and output an operation signal to the control unit 6.

[0032] Each stop switch 40 (40a, 40b, 40c) is provided in correspondence with each rotating reel 20 (20a, 20b, 20c). Stop switches 40a, 40b, and 40c accept operation to stop the rotation of the corresponding rotating reel 20a, 20b, and 20c while the reels are rotating. That is, when stop switch 40a is operated, the rotation of reel 20a stops; when stop switch 40b is operated, the rotation of reel 20b stops; and when stop switch 40c is operated, the rotation of reel 40c stops.

[0033] Lamps are provided inside the stop switches 40a, 40b, and 40c. The lamps can indicate, for example, that the stop switches 40a, 40b, and 40c are inoperable from the time the lever 42 is operated until each of the rotating reels 20a, 20b, and 20c reaches a constant speed rotation state, using a different color of light (e.g., red).

[0034] Information regarding the pressing of stop switches 40a, 40b, and 40c (information about which stop switch 40 was pressed, in what order they were pressed, and at what timing they were pressed) is used in the rotating reel control unit 611, game result determination unit 612, game state control unit 615, media management unit 620, etc., as described later.

[0035] The bet switch 41 is used when the operator places a bet on game value. The amount of credited game value and the amount of bet game value are managed by the slot machine 1 (media management unit 620). In the following, "credited game value" refers to the game value (game value data) managed by the media management unit 620.

[0036] Lever 42 functions as a start switch that accepts input to rotate the reels 20a, 20b, and 20c.

[0037] The digital counter 43 digitally displays the number of credits in game value, the number of payouts (acquired) of game value, and other information. By checking the digital counter 43, the operator can also check the amount of game value they possess while playing.

[0038] In this embodiment, "the number of game value payouts" does not refer to the actual action of dispensing tokens to the outside of the slot machine 1, but rather to "an increase in game value based on the winning combination determined by the internal lottery, corresponding to that combination." In other words, "the number of game value payouts" means "an increase in the numerical value of the digitized pseudo-game medium." Furthermore, for example, "a predetermined number of game value" is a concept equivalent to the conventional "a predetermined number of tokens."

[0039] The counting button 44 can receive input from the operator to transfer game value data from the media management unit 620 to the card unit 7. When the counting button 44 receives input from the operator, a transfer signal is generated by the counting button 44.

[0040] In this embodiment, the counting button 44 is positioned in a location visible to the operator of the slot machine 1.

[0041] More specifically, as shown in Figures 1 and 2, the counting button 44 is located on the side of the operating unit 4 that is closer to the card unit 7 when viewed from the front of the slot machine 1.

[0042] Furthermore, the counting button 44 may be equipped with a lamp inside or around it that changes its illuminated color before and after it is operated.

[0043] The cancel button 45 can accept an operation from the operator to change the game value from a bet state (bet state) to an unbet state (non-bet state). When the cancel button 45 accepts an operation from the operator, the cancel button 45 generates a cancel signal. Subsequently, the media management unit 620, upon receiving the cancel signal, manages the game value data from the bet state as an unbet state.

[0044] For example, if the cancel button 45 is pressed while the game value during a bet is 1 or greater, the media management unit 620 updates the game value during the bet to "0" and adds the game value data that had been bet up to "0" to the credited game value data. As a result, the number of credits displayed by the digital counter 43 increases by the amount of the game value data that had been bet. In other words, the cancel button 45 is a button that causes the media management unit 620 to execute a bet cancellation process, which resets the game value during a bet back to the number of credits by transitioning from a bet state to a non-bet state.

[0045] The bet cancellation process based on pressing the cancel button 45 is effective when the player is in a bet state but the lever 42 has not yet been operated. On the other hand, the bet cancellation process is disabled from the time the lever 42 is operated until the game based on the operation of the lever 42 is completed.

[0046] The effect button 46 is used, for example, to display the menu screen when a predetermined time (for example, 5 minutes) has not elapsed since the game was in standby mode, and to change the effect image when, for example, "PUSH!!" is displayed on the LCD screen 3 during gameplay.

[0047] Furthermore, the performance button 46 is equipped with a lamp that can emit light in various colors and patterns. The lamp lights up when the performance button 46 is operational and turns off when it is inoperable. In addition, when the performance button 46 is operated, a winning notification animation for a special role or other advantageous game state is output, and the lamp can flash rapidly in a different color than when it is normally lit, such as red or rainbow.

[0048] As shown in Figure 1, the confirmation key 47 includes an up key 47a, a down key 47b, a left key 47c, a right key 47d, and a selection button 47e. The player can select one of the displayed items by operating one of the up key 47a, down key 47b, left key 47c, or right key 47d, and then operating the selection button 47e.

[0049] Furthermore, the confirmation key 47 is equipped with a lamp that can illuminate in various colors and patterns. The lamp lights up when the confirmation key 47 is operational and turns off when it is inoperable.

[0050] Furthermore, as shown in Figure 2, a reset button 51 and a setting key 52 are provided inside the casing 10.

[0051] The reset button 51 is operated to clear various errors and to initialize the RAM that constitutes the control unit 6. For example, if the power to the slot machine 1 is switched from off to on while the reset button 51 is being operated, the amount of game value managed by the media management unit 620 is cleared to "0".

[0052] The setting key 52 is a key for switching to the setting change mode and is located inside the casing 10. The setting value control unit 613, described later, turns on the setting confirmation mode when the setting key 52 is turned on while the power to the slot machine 1 is still on, and turns off the setting confirmation mode when the setting key 52 is turned off while the power to the slot machine 1 is still on. In addition, the setting value control unit 613 turns on the setting change mode when the power to the slot machine 1 is turned on from off while the setting key 52 is on, and turns off the setting change mode when the setting key 52 is turned off from on while the setting change mode is on.

[0053] During gameplay or while waiting for gameplay, the cabinet 10 and the front door 100 are locked, so only those authorized to unlock them (for example, store staff who possess the key) can touch the reset button 51 and the setting key 52.

[0054] The setting value represents the payout rate, which is the ratio of the total amount of game value paid out to the total amount of game value inserted into slot machine 1. The set setting value affects the internal lottery. Depending on the setting value, the probability of winning at least some of the potential winning combinations will differ. The setting value is set by the store staff before the store opens.

[0055] Furthermore, as shown in Figure 2, the slot machine 1 includes a rotating reel unit 2 and a control unit 6. The rotating reel unit 2 and the control unit 6 are located inside the housing 10, along with a power supply (not shown) that turns the main power of the slot machine 1 on and off.

[0056] As shown in Figures 1 and 2, the rotary reel unit 2 comprises three rotary reels 20a, 20b, and 20c, and three stepping motors 21a, 21b, and 21c. The rotary reel unit 2 is positioned inside the housing 10, corresponding to the position of the reel window 200.

[0057] The surfaces of the rotating reels 20a, 20b, and 20c are arranged with symbols, for example, as shown in Figure 3. When the rotation of the rotating reels 20a, 20b, and 20c stops, the game proceeds when the game result determination unit 612 (described later) determines whether the combination of symbols displayed on the active line (described later) is a predetermined combination of symbols.

[0058] The stepping motors 21a, 21b, and 21c are provided in accordance with the rotary reels 20a, 20b, and 20c, and drive the corresponding rotary reels 20a, 20b, and 20c.

[0059] The stepping motors 21a, 21b, and 21c stop the rotation of the rotating reel 20 (e.g., 20a) corresponding to the operated stop switch 40 (e.g., 40a) within 190 milliseconds after the stop switches 40a, 40b, and 40c are operated while the rotating reels 20a, 20b, and 20c are rotating. The stepping motors 21a, 21b, and 21c complete one rotation in 504 steps. As a result, the rotating reels 20a, 20b, and 20c rotate at a speed of 80 revolutions per minute. That is, the number of steps advanced within 190 milliseconds is 127 steps.

[0060] Furthermore, in the special feature implementation state (in this embodiment, the Type 2 BB implementation state), which is the state in which the special feature described later (in this embodiment, the Type 2 BB continuous operation device for the Type 2 special feature) is being executed, the stepping motors 21a, 21b, and 21c can stop the rotation of at least one of the rotating reels 20a, 20b, and 20c (for example, rotating reel 20a) within 75 milliseconds after the corresponding stop switch 40 (for example, stop switch 40a) is operated.

[0061] These rotating reels 20a, 20b, 20c and stepping motors 21a, 21b, 21c are controlled by a rotating reel control unit 611, which will be described later, to control their rotation and stopping.

[0062] <Gameplay flow by the operator> The operator bets game value on slot machine 1 using the credited game value by operating the bet switch 41. Once a fixed number of game values ​​(2 or 3 in this embodiment) has been bet, the active line L is activated. After that, it becomes possible to operate the lever 42, i.e., to start playing.

[0063] This embodiment describes an example in which a predetermined number (2 or 3) of game value, which allows for one game to be played, is automatically bet by pressing the bet switch 41 once.

[0064] The active line L is a virtual line used to determine winning combinations. In this embodiment, one line is activated when the bet switch 41 is operated while the amount of game value required to play one game (a predetermined number) is credited.

[0065] In this embodiment, two types of game values ​​are provided as predetermined numbers: a game value of 2 and a game value of 3. When the special winning state ends, the game value is fixed to one of the predetermined numbers, either 2 or 3.

[0066] Specifically, in the slot machine 1 of this embodiment, if the special role that ended immediately before was type BBb, the subsequent game value is fixed at "3", and if the special role that ended immediately before was type BBa, the subsequent game value is fixed at "2".

[0067] In this embodiment, the active line L changes depending on the specified number. Specifically, as shown in Figure 1, when the game is being played with the specified number "2", the active line L becomes the downward-sloping active line L1, and when the game is being played with the specified number "3", the active line L becomes the upward-sloping active line L2. Hereafter, active lines L1 and L2 may be collectively referred to simply as "active line L".

[0068] In the slot machine 1 disclosed herein, once the game value of either 2 or 3 is fixed to a predetermined number, the game cannot proceed with any predetermined number other than the fixed number until a special win occurs. Then, when the fixed predetermined number of 2 or 3 is bet and the lever 42 is operated, one game can be played. If a replay is won, the next game will be played again with the predetermined number fixed in the game in which the replay was won.

[0069] In the following, "winning" refers not only to the alignment of symbols that produce payouts such as bells and watermelons on an active payline, but also to the alignment of symbols corresponding to specific roles that do not produce payouts, such as replays, chance symbols, and special roles (bonuses) like RB and BB, on an active payline.

[0070] In this embodiment, one game (one play) refers to a series of actions taken by a player to obtain a predetermined game result, including internal lottery, prize determination processing, and processing to increase or decrease game value data, by operating the bet switch 41, lever 42, and stop switches 40a, 40b, 40c, etc.

[0071] Specifically, when the lever 42 is operated (lever on) in a state where the game can be started, an internal lottery is held to determine the winning flag, and the reels 20a, 20b, and 20c begin to rotate. In this state, if any of the stop switches 40a, 40b, or 40c are operated, the reel 20 (20b) corresponding to the operated stop switch 40 (for example, 40b) stops.

[0072] All spinning reels 20a, 20b, and 20c stop, and a predetermined number of game values ​​are paid out according to the combination of symbols (winning combinations) that lined up (won) on the active lines. This completes one game.

[0073] Furthermore, at least some of the information regarding the progress of the game until these predetermined game results are obtained (for example, that the bet switch 41 was operated, that the lever 42 was operated, that the stop switch 40 was operated, that an internal lottery was performed, that a predetermined combination was won, that the spinning reels rotated, etc.) is managed by the main control unit 61.

[0074] <Regarding the game status> During gameplay, one game state is selected from among several game states, as shown in Figure 4. Based on the selected first game state, an internal lottery and a predetermined lottery are performed.

[0075] As shown in Figure 4, the first game state includes the state where special roles are not carried over, the internal bonus state (with special roles carried over), and the state where special roles are performed. The state where special roles are not carried over, the internal bonus state, and the state where special roles are performed are mutually exclusive.

[0076] In this embodiment, the two types of special roles, BB, include BBa (an example of the first special role) and BBb (an example of the second special role).

[0077] Two types of BBa are special symbols that, upon winning, trigger a fixed number of symbols after the bonus ends, set to "2". Two types of BBb are special symbols that, upon winning, trigger a fixed number of symbols after the bonus ends, set to "3".

[0078] In the following, Type 2 BBa and Type 2 BBb may be collectively referred to simply as "Type 2 BB." Similarly, the state of implementing Type 2 BBa and the state of implementing Type 2 BBb may be collectively referred to simply as "the state of implementing Type 2 BB."

[0079] The "no special role carryover" state refers to a state in which no special role has been won through internal drawing and no special role wins have been carried over. The "no special role carryover" state is set, for example, when the setting value described below is changed, when the RAM is initialized (one example of a specific condition), or when the game value exceeds a predetermined number in the special role execution state.

[0080] The bonus internal state refers to a state where a special role has been selected through an internal draw, but the winning of that special role has not yet been awarded. In other words, the bonus internal state refers to a state where a flag for a special role has been selected through an internal draw, but the symbols indicating that special role have not yet lined up on an active payline, and therefore the special role has not yet been awarded.

[0081] Specifically, the internal state remains that of a Type 2 BBa until the symbols corresponding to the Type 2 BBa are aligned after a Type 2 BBa is won, and the internal state remains that of a Type 2 BBb until the symbols corresponding to the Type 2 BBb are aligned after a Type 2 BBB is won. In this embodiment, as described later, in the game in which a Type 2 BB is won, the "scattered symbols (an example of the second symbol)" are always drawn onto the active line L and enter the game, so the internal bonus state does not carry over to the game following the game in which a Type 2 BB is won.

[0082] The "Special Role Implemented" state refers to a state in which a Type 2 BBa or Type 2 BBb has been awarded through an internal draw, but the termination conditions for the Type 2 BBa Implemented state or the Type 2 BBb Implemented state have not been met.

[0083] Furthermore, the special role implementation states of this embodiment include the Type 2 BBa implementation state, which is implemented when a Type 2 BBa is awarded, and the Type 2 BBb implementation state, which is implemented when a Type 2 BBa is awarded.

[0084] Furthermore, both the Type 2 BBa and Type 2 BBB states end after a payout of game value exceeding 150 (an example of a predetermined number). More specifically, in the Type 2 BBa and Type 2 BBB states, the state continues until, for example, a 15-coin payout is achieved in each game, and a game value exceeding 150 is paid out.

[0085] Additionally, the 2nd type BBa is awarded when a scattered pattern, such as a bell symbol, a replay symbol, and a cherry symbol, aligns on the active line L (L1 when the game is progressing with a specified number of "2", L2 when the game is progressing with a specified number of "3"; the same applies hereafter). Specifically, the 2nd type BBa is awarded when a bell symbol stops on the left spinning reel 20a, a replay symbol stops on the middle spinning reel 20b, and a cherry symbol stops on the right spinning reel 20b on the active line L.

[0086] On the other hand, the 2-type BBb is awarded when a set of scattered symbols, such as a bell symbol, a replay symbol, and a watermelon symbol, aligns on the active line L. Specifically, the 2-type BBb is awarded when a bell symbol stops on the left spinning reel 20a, a replay symbol stops on the middle spinning reel 20b, and a watermelon symbol stops on the right spinning reel 20b on the active line L.

[0087] Generally, special winning combinations consist only of the number 7, making them easy for players to recognize. However, in this embodiment, both Type 2 BBa and Type 2 BBb are composed of symbols that make it difficult for players to recognize special winning combinations that consist of the number 7 (an example of the first symbol; for example, a red 7 or a white 7). In other words, both Type 2 BBa and Type 2 BBb are not composed of the number 7, but of scattered symbols.

[0088] Then, if two types of BBa and two types of BBB are won, the pull-in control described later is executed, and the rotating reels 20a, 20b, and 20c are controlled so that the scattered symbols always line up on the active line L.

[0089] Furthermore, the Type 2 BB (Big Bonus) state transitions to a state where special bonuses are not carried over when the termination conditions are met, that is, when the aforementioned specific conditions are met, or when the game value exceeds a predetermined number (150) and is paid out.

[0090] <About Bonus Triggers> The slot machine 1 of this embodiment is a model equipped with a bonus trigger function. The bonus trigger function in this embodiment will be described below.

[0091] In the bonus trigger function of this embodiment, as described above, two types of special roles, Type 2BBa and Type 2BBb, are provided, and when the special role execution state based on these special roles ends, the subsequent predetermined number is fixed (determined) according to the type of special role execution state.

[0092] As mentioned above, in games played after the completion of the two types of BBa, the specified number is fixed at "2", and in games played after the completion of the two types of BBb, the specified number is fixed at "3". When the specified number is fixed at "3", it is not possible to play one game by betting only "2" in game value. When the specified number is fixed at "2", it is not possible to play one game by betting "3" in game value.

[0093] Thus, in the bonus trigger function of this embodiment, during gameplay after the special role execution state has ended, the number of balls is fixed to one predetermined number, and the payout performance is determined according to this fixed predetermined number.

[0094] For example, in games played after the completion of the two types of BBb, the specified number is fixed at "3," and the probability of winning a type of BBb becomes 1 / 600, while the probability of winning a type of BBa becomes 1 / 300.

[0095] On the other hand, in games played after the end of the two types of BBa, the specified number is fixed at "2," and the payout performance is as follows: the probability of winning the two types of BBa is 1 / 60, and the probability of winning the two types of BBa is 1 / 30.

[0096] Thus, when the 2-type BBa ends, the number of subsequent stipulated numbers is fixed at "2". As a result, the amount of game value required for one game becomes less than when the 2-type BBb ends, and the probability of winning a special prize becomes higher than when the 2-type BBb ends. Therefore, when the number of stipulated numbers is fixed at "2", it can be said to be a "high-probability section for 2-type BB".

[0097] <Configuration of Control Unit 6> The control unit 6 consists of a main control unit 61, a game value control unit 62, and a sub-control unit 63.

[0098] The main control unit 61, the game value control unit 62, and the sub-control unit 63 each consist of a microcontroller and a memory unit (ROM, RAM, RWM).

[0099] The connection relationships and communication processing of the main control unit 61, the game value control unit 62, and the sub-control unit 63 will be explained below with reference to Figure 6. In this embodiment, the main control unit 61 and the game value control unit 62 are mounted on the same board, the main control board PM, but the sub-control unit 63 is mounted on a different board, the sub-control board PS.

[0100] The information and commands generated by the main control unit 61 of the main control board PM include external terminal information, whether or not settings are being changed, commands related to various errors, a bet request signal for game value when the bet button 41 is operated, a payout request signal for game value corresponding to the winning combination, a bet cancellation request signal when the cancel button 45 is operated, and a transfer request for game value when the counting button 44 is operated.

[0101] Furthermore, the information and commands generated by the game value control unit 62 of the main control board PM include information indicating that the complete function (described later) has been activated, information indicating that the number of credits has reached the upper limit (a value used to prompt the player to transfer credits because the number of credits is too high), information regarding whether or not there is a communication abnormality between the card unit 7 and the slot machine 1, and various responses to requests from the main control unit 61.

[0102] Furthermore, the main control unit 61 and the game value control unit 62 of the main control board PM are capable of bidirectional communication with each other.

[0103] The main control board PM and the sub-control board PS are electrically connected by a harness, but only one-way serial communication takes place from the main control board PM to the sub-control board PS.

[0104] Information and commands transmitted from the main control board PM to the sub-control board PS include game data such as game status and game section, game value data (e.g., bet / payout information for game value, total number of game values ​​acquired during AT), information indicating the start / end of gameplay, information indicating the start / end of mechanism operation, information regarding various errors, information regarding the number of replay wins, information regarding the game status, the range (MY) described later, information indicating the operation of the complete function, commands regarding advance notification before the complete function is activated, information regarding the transfer of game value (e.g., transfer start, transfer in progress, transfer complete, etc.), information indicating the number of credits or acquired, information indicating that the number of credits has reached the upper limit, and error information if a credit backup error has occurred.

[0105] <Main Control Unit 61> The ROM of the main control unit 61, which is mounted on the main control board PM, stores programs and various data that are directly related to the progress of the game (for example, control of the rotating reels 20, payout control, and requests for transfer of game value).

[0106] The RAM and RWM of the main control unit 61 store game data (information related to the progress of the game) necessary for the game to proceed.

[0107] The main control unit 61 consists of a microcontroller mounted on the main control board PM and functions as an internal lottery unit 610, a rotating reel control unit 611, a game result determination unit 612, a set value control unit 613, a game state control unit 615, and an error determination unit 617.

[0108] In other words, in this embodiment, the main control unit 61 performs control that is directly related to the progress of the game. Specifically, the control performed by the main control unit 61 includes, for example, internal lottery processing, control of the rotating reels 20a, 20b, and 20c, various game states, various error monitoring such as monitoring of communication connection between the slot machine 1 and the card unit 7, and error processing.

[0109] Game data includes the current number of games played, as well as data indicating the game status (each game state). In this embodiment, game data includes, for example, data indicating that the first game state is a state where no special roles are carried over.

[0110] <Internal lottery section 610> The internal lottery unit 610 performs an internal lottery based on the operation of the lever 42 and selects one of the flags for multiple winning combinations as the winning flag. Specifically, the internal lottery unit 610 performs an internal lottery based on the first game state when the lever 42 is operated, according to the internal lottery table (not shown) and the random number obtained when the lever 42 is operated.

[0111] The internal lottery unit 610 then generates an internal lottery result signal based on the result of the internal lottery. The internal lottery result signal (an example of information related to the progress of the game) can be used by the reel rotation control unit 611, the game result determination unit 612, the game state control unit 615, and the performance control unit 630.

[0112] The internal lottery table shows information about the possible winning combinations through internal lottery. The internal lottery unit 610 performs an internal lottery based on the internal lottery table, according to the combination of RT state and bonus type when the lever 42 is operated.

[0113] Furthermore, the information on winning combinations shown in the internal lottery table includes one or more associations between symbol combinations and the winning combinations that correspond to those combinations.

[0114] Furthermore, the internal lottery unit 610 changes the internal lottery table used for the internal lottery according to a fixed number set by the media management unit 620, which will be described later.

[0115] <Rotating reel control unit 611> The rotary reel control unit 611 controls the drive of the stepping motors 21a, 21b, and 21c based on the operation of the lever 42 or each stop switch 40a, 40b, and 40c, and performs rotation start control to start the rotation of each rotary reel 20a, 20b, and 20c, or rotation stop control to stop the rotation.

[0116] Specifically, if the lever 42 is operated while all the rotating reels 20a, 20b, and 20c are stopped, the rotating reel control unit 611 will start the rotation of all the rotating reels 20a, 20b, and 20c.

[0117] Furthermore, in the case of rotation stop control during gameplay by the operator, the rotation reel control unit 611 performs pull-in control or kick-out control according to the winning combination drawn by the internal lottery and the position of the rotation reels 20a, 20b, and 20c corresponding to the operated stop switches 40a, 40b, and 40c. Pull-in control is a control that stops the rotation of the rotation reels 20 by pulling the symbols corresponding to the winning combination onto the active line. Kick-out control is a control that stops the rotation of the rotation reels 20 so that the symbols corresponding to the non-winning combination do not line up on the active line.

[0118] Then, when a Type 2 Big Bonus (BB) is won, the reel control unit 611 performs reel pull-in control to ensure that scattered symbols are always aligned on the active line L. As a result, a Type 2 Big Bonus is guaranteed to be awarded in the game in which it is won. In this case, the reel pull-in control is performed so that up to 4 symbols slide.

[0119] Furthermore, during the Type 2 BB implementation state, the rotary reel control unit 611 can stop the rotation of at least one of the rotary reels 20a, 20b, and 20c within 75 milliseconds after the corresponding stop switch 40 is operated, for the rotary reel 20a, 20b, and 20c corresponding to the operated stop switch 40a, 40b, and 40c.

[0120] Furthermore, if a Type 2 BBa is won and the pseudo-game lottery described later is also won, the reel control unit 611 will execute a reel animation in the pseudo-game where the 7 symbol aligns, triggered by the lever 42 being operated in the game following the win of the Type 2 BBa. This allows the player to recognize that the "high probability section for Type 2 BBs," in which the game is progressing with the specified number being "2," is continuing.

[0121] <Game result determination unit 612> The game result determination unit 612 can determine the game result based on the results of the internal lottery conducted by the internal lottery unit 610 and the stopping patterns of the symbols when each reel 20 stops rotating. The game result includes, for example, whether or not a winning combination was achieved.

[0122] Specifically, a winning combination is determined when the combination of symbols that stops on an active line matches a predetermined combination of symbols. This determination result (an example of information regarding the progress of the game) is transmitted as a game result determination signal to the game value control unit 62 and the sub-control unit 63, etc.

[0123] <Setting value control unit 613> The setting value control unit 613 sets one of several setting values ​​(for example, 1 to 6) that have different advantages in controlling the progress of the game, based on the operation of the setting key 52 by the store staff. This setting value is set for each slot machine 1. The setting value information (setting value signal) set by the setting value control unit 613 can be used by the internal lottery unit 610, the performance control unit 630, etc.

[0124] The degree of advantage in gameplay, such as the payout rate and the probability of winning specific small wins, differs depending on which setting value is used. For example, the higher the setting value (for example, the closer it is to 6), the greater the advantage in gameplay (for example, the higher the payout rate).

[0125] <Game state control unit 615> The game state control unit 615 sets the first game state.

[0126] Specifically, the game state control unit 615 sets the first game state to one of the following: a state where special roles are not carried over, a bonus internal state, or a state where special roles are being performed.

[0127] The game state control unit 615 sets the first game state to a state where no special roles are carried over, for example, immediately after the RAM of the main control unit 61 is cleared.

[0128] If a special role is drawn through internal lottery but the special role has not yet been awarded, the game state control unit 615 sets the first game state to the bonus internal state.

[0129] In the bonus internal state, if certain conditions are met (for example, if the RAM is cleared or if a setting value is changed), the game state control unit 615 transitions the first game state from the bonus internal state to the state where no special role is carried over.

[0130] In the state where no special role is carried over, if a special role is won (from this point until the special role is awarded, the game is in the bonus internal state), and a special role is awarded, the game state control unit 615 transitions the first game state from the state where no special role is carried over to the state where a special role is awarded, via the bonus internal state.

[0131] Furthermore, when a special role is achieved during the bonus internal state, the game state control unit 615 transitions the first game state from the bonus internal state to the special role execution state.

[0132] Furthermore, in the Type 2 BB implementation state, if the termination conditions are met, that is, if specific conditions are met, or if the game value exceeds a predetermined number (150), the game state control unit 615 transitions the first game state from the Type 2 BB implementation state to the special role non-carryover state.

[0133] The game state control unit 615 can transmit information regarding the first game state to the performance control unit 630 and other units as information regarding the progress of the game.

[0134] If a Type 2 BBa is won, the Game State Control Unit 615 executes a simulated game draw in the game in which the Type 2 BBa was won. If this simulated game draw is successful, the Game State Control Unit 615 executes a simulated game based on the operation of the lever 42 in the game following the game in which the Type 2 BBa was won. Based on this, the Rotating Reel Control Unit 611 executes a reel animation during this simulated game in which the 7 symbol is aligned on the active line L.

[0135] On the other hand, the game state control unit 615 does not execute a simulated game draw if a type 2 BBb is won. Therefore, in the game following a win of type 2 BBb, the reel animation in which the 7 symbol aligns on the active line L in the simulated game is not executed.

[0136] <Error detection unit 617> The error determination unit 617 determines whether or not various errors occur. Examples of various errors include backup failure, communication failure between the main control board PM and the sub-control board PS, connection failure between the slot machine 1 and the card unit 7, and reaching the upper limit of the number of credits.

[0137] If the error determination unit 617 determines that at least one of these errors has occurred, a command indicating the error that occurred is sent from the main control unit 61 to the game value control unit 62 and the sub-control unit 63, respectively, as information regarding the error.

[0138] As a result, the game value control unit 62 can perform processing according to the nature of the error, such as backing up the game value being managed, and the sub-control unit 63 can perform processing to notify the LCD screen 3 and speaker 101 of the nature of the error that occurred.

[0139] <Game Value Control Unit 62> The ROM of the game value control unit 62, which is mounted on the main control board PM, stores programs and various data directly related to the management of game value.

[0140] The RAM and RWM of the game value control unit 62 store game data (information related to the progress of the game) necessary for managing the game value.

[0141] The game value control unit 62 consists of a microcontroller mounted on the main control board PM and functions as a media management unit 620 (an example of a game control unit) and a function operation unit 621.

[0142] <Media Management Department 620> The media management unit 620 manages the number of credits and bets for game value.

[0143] The media management unit 620 receives an input request (a request to input a predetermined number of game values) or a payout request (a request to pay out a predetermined number of game values) from the main control unit 61 and performs the following processing.

[0144] Specifically, the media management unit 620 decreases the number of credits (an example of information related to the progress of the game) according to the number of game values ​​bet when game values ​​are bet based on the player's actions (when a betting request is made), and increases the number of credits when game values ​​are credited based on the player's actions.

[0145] Furthermore, the media management unit 620 increases the number of credits according to the amount of game value paid out based on the type of winning combination, when a winning flag is established through an internal draw and a combination corresponding to the winning flag is awarded based on the player's actions (when a payout request is made).

[0146] Furthermore, as shown in Figure 5, the media management unit 620 calculates the difference in game value (an example of information related to the progress of the game), which is the cumulative value obtained by subtracting the number of game value bets from the number of game value payouts. The difference in game value is used to determine whether the complete function, described later, is activated or not.

[0147] Furthermore, as shown in Figure 5, the media management unit 620 uses the difference in game value, which is the cumulative value obtained by subtracting the number of bets for game value from the number of payouts for game value since the last time the slot machine 1 was powered on, to calculate the range (MY), which is the difference between the maximum and minimum values ​​of the difference.

[0148] Information regarding this range (MY) is used in the function operation unit 621 for the complete function, which will be described later.

[0149] The media management unit 620 resets the range (MY) when the power to slot machine 1 is turned off by store staff.

[0150] Furthermore, when the special prize execution state that was entered as a result of winning two types of BB ends, the media management unit 620 determines the subsequent prescribed number according to the type of special prize execution state that ended.

[0151] Specifically, the media management unit 620 determines the subsequent specified number to "3" when the Type 2 BBb execution state ends, and determines the subsequent specified number to "2" when the Type 2 BBa execution state ends. As a result of this determination, if the specified number is fixed at "2", a game value of 2 is bet with one operation of the bet switch 41 (MAX BET button), and if the specified number is fixed at "3", a game value of 3 is bet with one operation of the bet switch 41 (MAX BET button).

[0152] Furthermore, the media management unit 620 controls the game to prevent it from executing game progression based on a predetermined number other than a fixed predetermined number.

[0153] Furthermore, the number of bets, fixed predetermined number, number of credits, and difference in game value calculated by the media management unit 620 are transmitted as information related to the progress of the game to the internal lottery unit 610, the spinning reel control unit 611, the game state control unit 615, the performance control unit 630, and so on.

[0154] <Functional operating part 621> The functional operation unit 621 uses the range (MY) information generated by the media management unit 620 to perform processes related to prior notification.

[0155] The function activation unit 621 generates information regarding a pre-notification indicating that the complete function is about to be activated when the range (MY) becomes, for example, 18500 or higher.

[0156] This complete function is a so-called stop function. When the complete function is activated, slot machine 1 will no longer accept any input related to gameplay, and the operator will not be able to continue playing unless the power is turned off and on by a store staff member (the game will be unplayable).

[0157] The operations related to gameplay referred to here mean the operations required to complete one game, and specifically include the operation of the bet switch 41 to bet game value as an operation to start the spinning reels 20. When the complete function is activated, such gameplay operations will not be accepted, so even if the bet switch 41 is operated while the complete function is activated, the bet for game value will not be processed. The complete function will operate regardless of whether the fixed number at the time of activation is "2" or "3".

[0158] Furthermore, information regarding the advance notification is transmitted to the performance control unit 630 for each game, for example, while this information is being generated in the function operation unit 621. As a result, the performance control unit 630 issues the advance notification.

[0159] Furthermore, when the range (MY) falls below the first range of 18500, the function operation unit 621 stops generating information related to advance notification. As a result, advance notification is no longer issued by the performance control unit 630.

[0160] Furthermore, the information regarding the advance notification may be a flag that turns the advance notification notification on or off. In this case, when the advance notification notification changes from off to on, the information that the flag is "on" is transmitted to the performance control unit 630, and conversely, when the advance notification notification changes from on to off, the information that the flag is "off" is transmitted to the performance control unit 630. By using a flag format for the information regarding the advance notification in this way, it is possible to suppress an excessive amount of signals transmitted from the main control unit 610 to the sub-control unit 630.

[0161] Furthermore, the function activation unit 621 activates the complete function when the range (MY) becomes 19000 or higher, which is the second range.

[0162] The function activation unit 621 deactivates the complete function when the store staff turns off the power to slot machine 1. When the power to slot machine 1 is turned on again, not only is the complete function deactivated, but the range (MY) is also reset to 0 (zero). Therefore, no prior notification is given, and the conditions for the complete function to activate again are not met, making it possible to play slot machine 1.

[0163] <Sub-control unit 63> The ROM of the sub-control unit 63 stores programs and various data that are indirectly involved in the progress of the game (for example, controlling the effects on the LCD screen 3, controlling the LED illumination of the lighting unit 102, and controlling the sound output of the speaker 101).

[0164] The RAM and RWM of the sub-control unit 63 store various data related to performance control.

[0165] The sub-control unit 63 consists of a microcontroller mounted on the sub-control board PS and functions as the performance control unit 630.

[0166] <Performance Control Unit 630> The performance control unit 630 performs a performance lottery and determines at least one of the following as a performance pattern: a video / still image output on the LCD screen 3, a sound pattern output from the speaker 101, a light emission pattern of the LED or other lighting unit 102, or a light emission pattern of the performance button 46.

[0167] Specifically, the performance control unit 630 selects a performance lottery table based on game progress information (e.g., game state, stay mode) transmitted from the main control unit 61, and performs a performance lottery using the selected performance lottery table.

[0168] Furthermore, the performance control unit 630 can display on the LCD screen 3 that it is in a high-probability zone for two types of Big Bonuses while the game is progressing with the specified number being "2".

[0169] Furthermore, the performance control unit 630 can remove the display indicating that it is a high-probability section for Type 2 BB from the LCD screen 3 when the Type 2 BB implementation state based on a Type 2 BB that was won while the game was in progress with a predetermined number of "2" has ended.

[0170] <Basic operation flow of slot machine 1> Figure 7 will be used to explain the basic operation flow of slot machine 1.

[0171] The flow branches based on whether slot machine 1 is playable (whether the complete function is active or not) after the power to slot machine 1 has been turned on and the settings have been changed (step S101).

[0172] If slot machine 1 is not in a playable state (S101: NO), the process proceeds to step S109, which will be described later.

[0173] On the other hand, if slot machine 1 is in a playable state (S101: YES), provided that game value data has been transmitted from card unit 7, the main control unit 61 and game value control unit 62 of slot machine 1 display the amount of credited game value on the digital counter 43 and accept operations from the operator such as bet switch 41 and lever 42. As a result, slot machine 1 enters a play start state (step S102).

[0174] Next, the media management unit 620 starts calculating the range (MY) (step S103). After that, the media management unit 620 calculates the range (MY) for each game.

[0175] Next, if a special role of RB or BB is won and awarded, the flow branches based on whether the first game state is a special role execution state or not (step S104).

[0176] If the first game state is not a state where a special role is being played (S104: NO), the process repeats step S104.

[0177] On the other hand, if the first game state is a special role execution state (S104: YES), the flow branches based on whether or not the special role execution state has ended (step S105).

[0178] If the special role execution state has not ended (S105:NO), the process repeats step S105.

[0179] On the other hand, when the special role execution state ends (S105: YES), the flow branches based on whether or not the complete function is activated (step S106). Specifically, the flow branches based on whether or not the range (MY) is 19000 or greater.

[0180] If the complete function is not working (S106: NO), the process proceeds to step S104.

[0181] On the other hand, if the complete function is activated (S106: YES), the function activation unit 621 controls the machine so that the operator cannot proceed with playing the slot machine 1 (step S107).

[0182] Next, in response to the operation of the counting button 44, the media management unit 620 and the card unit 7 send and receive the necessary information to execute the transfer process (step S108).

[0183] Next, in response to the store staff's power-off operation, the power to slot machine 1 is turned off (step S109). In response, the media management unit 620 initializes the range (MY) to 0 (zero), and the function activation unit 621 cancels the complete function (step S110).

[0184] Next, in response to the store staff's power-on operation, the power to slot machine 1 is turned on (step S111). After that, the process returns to step S101. The above is the basic operation flow of slot machine 1.

[0185] <Flowchart for fixed number of entries, including processing of two types of BB wins> Next, we will explain the fixed number of processes, including the process for awarding two types of BBs, using Figure 8.

[0186] First, the game state control unit 615 proceeds with the game in a state where no special roles are carried over (step S201).

[0187] Furthermore, the media management unit 620 sets the currently fixed predetermined number (step S202).

[0188] Next, the flow branches based on whether or not the internal draw resulted in winning one of the two types of BBa (step S203).

[0189] If the player wins two types of BBa (S203: YES), the game state control unit 615 performs a simulated game lottery in that game, and the reel rotation control unit 611 draws in scattered symbols, such as the bell symbol, replay symbol, and cherry symbol, onto the active line L based on the player's operation of the stop switches 40a, 40b, and 40c, thereby awarding two types of BBa (step S204).

[0190] Next, the flow branches based on whether or not the player won the pseudo-game lottery executed in the game in which they won one of the two types of BBa (step S205).

[0191] If the simulated game lottery is not won (S205: NO), the process proceeds to step S207, described below, based on the operation of lever 42 in the next game.

[0192] On the other hand, if the simulated game lottery is won (S205: YES), the game state control unit 615 executes the simulated game based on the operation of the lever 42 in the next game, and the reel rotation control unit 611 stops the 7 symbol on the active line L in the simulated game based on the operation of the stop switches 40a, 40b, and 40c (step S206).

[0193] Next, the game state control unit 615 executes the two types of BBa implementation states (step S207).

[0194] Next, the flow branches based on whether the two BBa execution states have been completed or not (step S208).

[0195] If the execution status of type 2 BBa has not been completed (S208:NO), the process proceeds to step S207.

[0196] On the other hand, if the execution of the two types of BBa is completed (S208: YES), the media management unit 620 fixes the specified number to "2" (step S209). After that, the process of fixing the specified number, including the process of awarding the two types of BBa, is completed.

[0197] Returning to step S203, if the winner has not been selected for type BBa (S203: NO), the flow branches based on whether or not the winner was selected for type BBb as a result of the internal draw (step S210).

[0198] If you have not won a BBb of type 2 (S210: NO), the process proceeds to step S203.

[0199] On the other hand, if a 2-type BBb is won (S210: YES), in that game, the reel control unit 611 pulls in scattered symbols, such as the bell symbol, replay symbol, and watermelon symbol, onto the active line L based on the player's operation of the stop switches 40a, 40b, and 40c, and awards a 2-type BBb (step S211).

[0200] Next, the game state control unit 615 executes two types of BBb execution states based on the operation of the lever 42 in the next game (step S212).

[0201] Next, the flow branches based on whether the two types of BBb implementation states have been completed or not (step S213).

[0202] If the BBb implementation status for type 2 is not completed (S213: NO), the process proceeds to step S212.

[0203] On the other hand, if the two types of BBb execution state is completed (S213: YES), the media management unit 620 fixes the specified number to "3" (step S214). After that, the process of fixing the specified number, including the two types of BB prize winning process, is completed. Following the above procedure, a fixed number of processes, including the processing for winning two types of Big Bonuses, will be executed.

[0204] In summary, the slot machine 1 disclosed herein is: It features multiple rotating reels 20a, 20b, and 20c, each with multiple symbols arranged on it. It is possible to conduct a draw for multiple roles, including multiple types of special roles. There are several types (2 or 3) of prescribed amounts of game value required to start the game. A special role that is a candidate for winning is determined according to the number of specified figures for each category. In the game after the execution of the special game state (2-type BBa execution state or 2-type BBB execution state) which is entered when a special role (2-type BBa or 2-type BBB) is won has finished, it is possible to determine the execution number, which is one of several types of prescribed numbers, as the bet amount. When the game is being played with a set number of "2", the probability of winning a special combination (2 types of BBa, 2 types of BBB) is higher than when the game is being played with a set number of "3". The symbols include the number 7 (an example of the first symbol) and scattered symbols (an example of the second symbol) that make it difficult to recognize special combinations (two types of BBa or two types of BBB). When the game is progressing with the specified number being "2", if two types of BBa (first special role) are won, the specified symbol pattern that aligns on the effective line L1 (an example of a specified line) consists of scattered symbols. When the game is in progress with the specified number being "2", if a Type 2 BBa is won, regardless of the timing of stopping the stop switches 40a, 40b, and 40c, the scattered symbols will be pulled in and line up on the active line L1, resulting in a Type 2 BBa being awarded.

[0205] <Effects of the invention> Gaming machines equipped with bonus features such as RB (Type 1 Special Feature) or BB (Continuous Activation Device for Type 1 Special Feature) have been known for some time.

[0206] In such gaming machines, players can choose the number of tokens to bet, for example, from 1, 2, or 3 tokens.

[0207] In conventional gaming machines, the probability of winning a bonus is set to differ depending on the number of tokens (a specified number) bet. For example, betting three tokens may make it easier to win a bonus than betting two or one token.

[0208] In recent years, gaming machines equipped with a bonus trigger function have been developed. These gaming machines, for example, are those in which the number of coins awarded is fixed at 3 or 2 after the end of an RB (Regular Bonus) or BB (Big Bonus) state. For example, in games played after the end of a BB state, the number of coins awarded may be fixed at 2, and in games played after the end of an RB state, the number of coins awarded may be fixed at 3.

[0209] Furthermore, in gaming machines equipped with a bonus trigger function, when a BB (Big Bonus) is won, that is, when the specified number is fixed at 2 coins, it is possible to make it easier to win a special role (BB or RB) than when the specified number is fixed at 3 coins. In other words, when the specified number is fixed at 2 coins, it can be said that the situation is more advantageous for the player than when the specified number is fixed at 3 coins.

[0210] However, in this case, the player may be able to determine whether the advantageous state of having a fixed number of 2 coins continues, based on whether they win a Big Bonus (BB) or a Regular Bonus (RB), while the number of coins is fixed at 2. In this case, it may become impossible to provide an interesting gaming machine.

[0211] In contrast, in this embodiment, two types of BBs are used as special roles. According to this disclosure, when the game is progressing with a predetermined number of "2" and a type BBa is won, regardless of the timing of the stop operation of the stop switches 40a, 40b, and 40c, the scattered symbols will always be drawn into and line up on the active line L1, and a type BBa will be awarded.

[0212] Therefore, it becomes difficult for players to recognize that they have won a Type 2 BBa. On the other hand, in subsequent games, the Type 2 BBa state begins, increasing the payout, and after the Type 2 BBa state ends, the game proceeds with the regulated number being "2". As a result, it is possible to provide an interesting gaming machine.

[0213] Thus, according to this disclosure, it is possible to provide an interesting gaming machine equipped with a bonus trigger function.

[0214] [Other embodiments] The various control means and processing procedures described in the above embodiments are examples and are not intended to limit the scope of this disclosure, its applications, or its uses. The various control means and processing procedures can be modified as appropriate without altering the gist of this disclosure. Furthermore, the various control means, processing procedures, and processing contents described in each embodiment can be configured individually or combined as appropriate.

[0215] Furthermore, unless otherwise specified for each example, the various definitions used herein are used in common throughout the specification.

[0216] In the embodiments described above, the specified number was "3" or "2," but the disclosure is not limited thereto. For example, the specified number may be "2" or "1." However, in this case, if the specified number is "1," the probability of winning a special prize should be higher than when the specified number is "2." Furthermore, the specified number may instead be "3" or "1."

[0217] Furthermore, although the above embodiment described that the configuration of this disclosure is applicable to gaming machines equipped with a bonus trigger function, it cannot be applied to AT machines or ART machines.

[0218] Furthermore, the two types of BBa may consist of, for example, seven symbols. That is, the two types of BBa may consist of seven symbols, while only the two types of BBBb may consist of scattered symbols.

[0219] Furthermore, multiple types of 2-type BBa and / or 2-type BBb may be available, and at least one of them may consist of scattered symbols. This makes it even more difficult for players to determine whether or not the high-probability period of 2-type BB will continue.

[0220] Additionally, if the game is being played with a predetermined number of "2", the two types of BBa that are won will be awarded when the 7 symbols (for example, the red 7 symbols) line up, and if the game is being played with a predetermined number of "3", the two types of BBa that are won may also be awarded when the scattered symbols line up.

[0221] Additionally, if the game is being played with a predetermined number of "2", the two types of BBb will be awarded when the scattered symbols line up, and if the game is being played with a predetermined number of "3", the two types of BBb may also be awarded when the 7 symbols (for example, the white 7 symbols) line up.

[0222] Furthermore, in the above embodiment, an example was described in which, when a player wins two types of BBa and also wins a simulated game draw, a reel animation is performed in which the 7 symbol aligns on an active line during the simulated game. However, this disclosure is not limited to this.

[0223] For example, if a player wins a Type 2 BBa, a reel animation may be performed in the next game in a simulated game where the 7 symbol aligns on an active line. However, if the reel animation where the 7 symbol aligns on an active line is performed in a simulated game every time a player wins a Type 2 BBa, then in the above embodiment, the reel animation will not be performed if a player wins a Type 2 BBB. In this case, the player will be able to tell that they have won a Type 2 BBB, which may greatly increase their sense of loss. Therefore, it is preferable that the reel animation where the 7 symbol aligns on an active line is performed in a simulated game only when a player wins a Type 2 BBa and certain conditions are met.

[0224] In the above embodiment, the game state control unit was shown to perform a simulated game draw in the game in which a Type 2 BBa was won when a Type 2 BBa was won, but the present disclosure is not limited to this. For example, if a Type 2 BBa is won, a simulated game draw may be performed in the next game.

[0225] Furthermore, the embodiment is not limited to the above, and in games in which two types of BBa are won, a simulated game lottery may be performed, and if the simulated game lottery is won, an effect in which the 7 symbol stops in the simulated game may be performed in that game.

[0226] Furthermore, although the above embodiment described an example in which a simulated game draw was not performed when a type 2 BBb was won, a simulated game draw may also be performed when a type 2 BBb is won. In this case, if a type 2 BBb is won and the simulated game draw is also won, the 7 symbol will line up on the active line in the simulated game in the game following the win of the type 2 BBb. In this case, if the simulated game can also be performed when a type 2 BBa is won, it can be made difficult to distinguish whether a type 2 BBa or type 2 BBb was won.

[0227] Furthermore, in a state where the specified number is "2" and the game continues to progress, which is a "high probability zone for Type 2 Big Bonuses," even if a Type 2 Big Bonus (BBa) is not currently being played, a video presentation that gives the impression of a continuous bonus sequence may be executed. For example, the first video presentation may be displayed during the first instance of the high probability zone for Type 2 Big Bonuses, and the second video presentation may be displayed during the second instance of the high probability zone for Type 2 Big Bonuses. In this case, a pre-prepared series of video presentations may be available, and these presentations should be displayed in order according to the length of the high probability zone.

[0228] Furthermore, while the above embodiment described an example in which a standard-sized rotary reel was used, as shown in Figure 1, this disclosure is not limited to this. For example, a slot machine may employ mini-reels that are about half the size of the rotary reel in Figure 1 in both length and width.

[0229] Furthermore, the embodiment is not limited to the above-described embodiment. For example, the probability of winning a type BBb does not change whether the specified number is "2" or "3", but the probability of winning a type BBa may change depending on the specified number.

[0230] Furthermore, there are three or more special winning combinations, and the probability of winning two of these special combinations changes depending on whether the specified number is "2" or "3," but the probability of winning the remaining special combination does not need to change.

[0231] Furthermore, although not limited to the above embodiment, after a Type 2 BBa is awarded, after the Type 2 BBa execution state ends, or after a Type 2 BBa is awarded and the 7 symbol stops in the simulated game, the performance control unit may display on the LCD screen that it has entered the high probability section for Type 2 BB. Also, thereafter, after a Type 2 BBb is awarded for the first time, the performance control unit may display on the LCD screen that the high probability section for Type 2 BB has ended.

[0232] Furthermore, the predetermined symbol pattern composed of scattered symbols may include symbols that line up on the active line when a replay is won (for example, bell symbols, blank symbols, and replay symbols).

[0233] Furthermore, the winning symbols for type 2 BBa may differ depending on whether the game is being played with a specified number of "2" or with a specified number of "3". Similarly, the winning symbols for type 2 BBB may differ depending on whether the game is being played with a specified number of "2" or with a specified number of "3". For example, if the game is being played with a specified number of "2", the winning symbols for type 2 BBa may be the bell symbol, replay symbol, and cherry symbol, and if the game is being played with a specified number of "3", the winning symbols for type 2 BBa may be the replay symbol, cherry symbol, and bell symbol.

[0234] Furthermore, in the above embodiment, when the game is being played with a predetermined number of "2", an example was described in which scattered symbols line up on an active line when a 2-type BBa or 2-type BBB is won, but this disclosure is not limited to this. When the game is being played with a predetermined number of "2", when a 2-type BBa or 2-type BBB is won, the scattered symbols may line up on a predetermined line that is not an active line, such as a so-called small V line or a middle line.

[0235] Furthermore, although the above embodiment describes an example in which the bonus is a continuous activation device for a Type 2 special feature, the present disclosure is not limited thereto. The bonus may be any of a Type 1 special feature, a continuous activation device for a Type 1 special feature, a Type 2 special feature, or a continuous activation device for a Type 2 special feature.

[0236] Furthermore, while the range (MY) was used to activate the complete function in the above embodiment, the system is not limited to this, and the difference in game value may be used to determine whether or not to activate the complete function.

[0237] Furthermore, although the above embodiment described an example in which the medal unit is connected to the slot machine in a communicative manner outside the slot machine, this disclosure is not limited to this. The medal unit may be integrally housed within the casing of the slot machine together with the main control unit, etc., or it may be incorporated into the main control unit, for example, and function as part of the media management unit. In other words, in this specification, "connected" means both a state in which there is no intervention between the slot machine and the medal unit and they are directly connected, and a state in which something is intervening between them and they are indirectly connected.

[0238] Furthermore, although the slot machine in the above embodiment was a coinless machine, the slot machine to which this disclosure applies does not have to be a coinless machine. If the slot machine is not a coinless machine, it will have components such as a coin slot, a coin payout slot, and a hopper.

[0239] Furthermore, although the above embodiments describe an example of a so-called smartphone throttle, this disclosure is not limited thereto.

[0240] Furthermore, in the above embodiment, Figure 6 shows an example in which the main control unit and the game value control unit are mounted on the same control board, but the main control unit and the game value control unit may be mounted on separate control boards. Also, the main control unit and the game value control unit may be composed of separate microcontrollers, or they may be composed of the same microcontroller. [Explanation of symbols]
