Description

The present invention relates to gaming machines such as slot machines.

As a gaming machine of this type, one is known that is provided with a gaming period (AT) that makes it easier to obtain the profits of winnings by notifying the correct pressing order of the stop switch. Additionally, there are known machines that have an advantageous section which is a gaming section in which AT can be performed, and a normal section which is a gaming section in which AT cannot be performed.

Regarding such gaming machines, for example, Patent Document 1 discloses a gaming machine that has at least a first control state (precursor, CZ, AT) and a second control state (normal) as states controlled by a main control means. has been done. In the configuration described in Patent Document 1, the first control state is an advantageous section, and the second control state is a normal section. Then, on the condition that the advantageous section has started, a transition is made from normal to a precursor, and when the AT start condition is satisfied in a precursor, AT is started. After the end of AT, a transition is made to CZ (AT pullback period), and if the AT start condition is not satisfied during CZ, CZ is ended, a transition is made to normal, and the advantageous section is ended.

Japanese Patent Application Publication No. 2018-000808

However, in the gaming machine described in Patent Document 1 mentioned above, the expectation for AT is lost when the advantageous period ends (when it shifts to the normal period), so there is a problem that it may be the timing for the player to stop playing. there were.

Therefore, it is an object of the present invention to provide a gaming machine that can maintain expectations for AT even when the advantageous period has ended (when the period has shifted to the normal period).

The present invention has been made to solve the above problems, and has the following features.

That is, a rotating reel for displaying a plurality of symbols in a variable or stopped manner, a start switch for displaying symbols on the rotating reel in a variable manner, and a start switch provided corresponding to the rotating reel to display the symbols on the corresponding rotating reel. a stop switch for stopping the display; a winning lottery means for determining whether one of the plurality of winning combinations is won or lost; a winning combination table storing winning areas corresponding to the plurality of winning combinations; a reel control means for controlling the stop display of the symbols on the rotating reel based on the drawing result of the winning lottery means and the operation of the stop switch; a prize determining means for determining whether or not one of the plurality of winning combinations has been won based on the stop position; a gaming state control means for managing the gaming state; and an operating order of the stop switch. a press order notification means for notifying information regarding the press order notification means; a specific game control means for determining whether or not to start a specific game for activating the press order notification means by a specific game lottery; and a game section control for controlling the game section. and a mode management means for managing a plurality of modes with different winning probabilities of the specific game lottery, and the game section includes an advantageous section in which the specific game can be executed and a normal section in which the specific game cannot be executed. , the plurality of winning combinations include a BB combination that starts a BB game upon winning a prize, and the BB game is configured to end when a predetermined number of game media is acquired; The mode management means executes a mode transition lottery for determining the mode by referring to the number of coins remaining up to the specified number when transitioning to the advantageous section during the BB game, The mode change lottery is performed from the start to the end of the BB game so that the game always shifts to a mode more advantageous than the mode in which it was staying at the end of the previous advantageous section.

Further, the mode management means may manage the remaining number of tickets up to the specified number by dividing them into a plurality of zones, and may execute the mode transition lottery with a different lottery probability for each zone.

Further, the mode management means may stepwise determine the mode corresponding to the zone, and may be configured such that only a mode equal to or higher than the mode corresponding to the current zone is selected in the mode transition lottery.
Further, the game section control means may not end the advantageous section until the zone corresponding to the current mode ends.

The present invention is as described above, and the mode management means determines the mode by referring to the remaining number of cards up to the specified number when the BB game shifts to an advantageous section. Therefore, even if the advantageous section ends, the number of sheets remaining up to the specified number will have changed at the time of the next transition to the advantageous section, so it can be expected that the mode will shift to an advantageous mode. For example, if an advantageous period ends during a BB game, and then shifts to an advantageous period again during the same BB game, the number of remaining cards up to the specified number in the BB game has decreased, so the mode will be changed to a different mode than before. will be transferred. In this way, even if the advantageous section ends and you move to the normal section, you can expect to switch to a mode that is more advantageous than the mode you were in at the end of the previous advantageous section, so when the advantageous section ends ( Even when the game shifts to the normal section), the player's sense of anticipation can be maintained.

Further, the mode management means may execute a mode transition lottery for determining the mode when the mode transitions to an advantageous section during the BB game. With this configuration, the mode to which the game will be transferred is determined at random, making it possible to keep the player's heart racing. For example, even if a player is counting the number of coins he or she has won in a BB game, he or she cannot completely predict the mode to which the player will transition, resulting in an unpredictable game development.

Further, the mode management means may manage the remaining number of tickets up to the specified number by dividing them into a plurality of zones, and may execute the mode transition lottery with a different lottery probability for each zone. With this configuration, the drawing probability of the mode transition drawing can be varied in accordance with the progress of the BB game.

Furthermore, the mode management means may be configured to step-by-step determine the mode corresponding to the zone, and select only a mode equal to or higher than the mode corresponding to the current zone in the mode transition lottery. With this configuration, it is possible to realize a gaming machine in which the probability of winning the lottery increases step by step as the BB game progresses.

Further, the game section control means may not end the advantageous section until the zone corresponding to the current mode ends. According to such a configuration, in the mode transition lottery when moving to the next advantageous section after completing the advantageous section, it is possible to configure the mode to shift to a mode more advantageous than the current mode.

Note that the control device 20 is not limited to the above-mentioned means, and may include other means.

(Game state control means 100)
The gaming state control means 100 is for managing the gaming state. The slot machine 10 according to the present embodiment has a plurality of gaming states, and the gaming state control means 100 stores the current gaming state and changes the gaming state when a predetermined event that triggers the transition of the gaming state occurs. Execute the process of switching.

As shown in FIG. 4, the slot machine 10 according to the present embodiment has at least the following gaming states. This gaming state includes an RT state defined by the winning probability of the replay combination. Note that the game state is not limited to the following, and any game state can be provided. (1) RT0 state (general gaming state) (2) RT1 state (BB general medium state) (3) RT2 state (RB internal state during BB) (4) RT3 state (RB medium state during BB)

Among these, the RT0 state is an initial state set at the time of factory shipment or when changing settings. The RT0 state is entered when the settings are reset due to a change in settings or the end of an advantageous section. Also, when the BB game described later ends, the state shifts to RT0.

The RT1 state (BB general medium state) is a state where the BB winning combination is won and the BB game is being played. The state shifts to RT1 when the BB winning combination is won. In addition, in the BB game in this embodiment, when specific symbols are aligned during the BB game, the jack-in occurs and the game shifts to the RB game. When the number of medals acquired during the BB game reaches a specified number (for example, 300), the BB game ends.

The RT2 state (RB internal state during BB) is a state in which a winning flag related to the RB combination, which will be described later, is established during the BB game. The RT2 state is entered when the player wins the RB role in the RT1 state. Further, this RT2 state ends when the RB winning combination is won or when the BB game ends.

The RT3 state (RB during BB state) is a state in which an RB game, which will be described later, is being played during the BB game. The RT3 state is entered when the RB winning combination is won in the RT1 state or RT2 state. The RB game that starts when the RT3 state is entered is executed until a predetermined profit (a predetermined number of acquired medals or a predetermined number of games) is given to the player. Then, once a predetermined profit is given to the player, the RB ends and the RT3 state also ends.

(Winning lottery means 110)
The winning lottery means 110 is for performing a lottery to determine whether the player wins or loses one of a plurality of winning combinations. In other words, a drawing concerning a winning combination is performed based on a predetermined drawing probability. As a result of the drawing by the winning lottery means 110, if a predetermined winning combination is won, a winning flag is established, and while this winning flag is established, the combination of the symbols stopped on the rotating reel 40 is a predetermined winning symbol. It is set up so that a prize is won on the condition that there is a match, and the player is given benefits such as payouts of medals and special games.

Specifically, the winning lottery means 110 includes a random number generating means that generates random numbers within a predetermined range, extracts the random numbers generated by the random number generating means at the timing of operating the start switch 30, and uses the extracted random numbers as a prize. The lottery is performed by checking against the lottery table 120. The winning lottery means 110 according to the present embodiment generates 16-bit random numbers, and thus generates 65536 random numbers from 0 to 65535. In a winning combination table 120, which will be described later, a winning area is assigned to each of these 65536 random numbers, and by comparing the random numbers with this winning combination table 120, a winning combination or a loss can be specified.

The slot machine 10 according to the present embodiment has a bonus role that starts a bonus game upon winning, a replay role that allows you to play the game again without inserting new game medals upon winning, and a replay role that allows you to play the game again without inserting new game medals upon winning. It is equipped with a small role that pays out game medals.
Incidentally, the bonus combination includes a BB combination that starts a BB game upon winning, and an RB combination that starts an RB game upon winning.
The BB game is a bonus game that is played until a predetermined profit is given to the player, such as when a predetermined number of medals (210 medals) are paid out.

Further, the RB game is a bonus game that is executed until a predetermined profit is given to the player, but the profit is smaller than that of the BB game. The RB game in this embodiment is a so-called "decreasing bonus" that is set so that the expected value of acquisition of game media per bet game media is less than 1. Therefore, even if you end the RB game after receiving a predetermined profit (after a predetermined number of medals or a predetermined number of games have been played), you will receive more medals than before the start of the RB game. It is set to decrease.

(Roll lottery table 120)
The winning combination table 120 defines which winning combination or loss the random number extracted by the winning selection means 110 corresponds to. This winning combination table 120 stores winning areas corresponding to a plurality of winning combinations, and is specifically provided as a correspondence table between random numbers generated in the winning lottery means 110 and winning combinations. The winning lottery means 110 switches and uses these winning lottery tables 120 according to the game status, setting values, and the like. As a result, the winning probability varies depending on the gaming state.

(Reel control means 130)
The reel control means 130 rotates the rotary reel 40 based on a valid operation signal of the start switch 30, and draws a winning lottery while recognizing the current position of the symbol based on a detection signal from a reel rotation detection sensor (not shown). This is for controlling the stop of the rotating reels 40 based on the lottery result of the means 110 and the valid operation timing of the stop switch 50.

This reel control means 130 responds to the operation signal of the start switch 30 when predetermined game start conditions are satisfied, such as when medals are bet and a predetermined time (so-called wait time) has elapsed since the start of the previous game. Based on this, rotation of all rotating reels 40 is started.

Further, when any stop switch 50 is operated while the rotating reel 40 is rotating, a stop signal is output based on the operating signal of the stop switch 50, and the rotation of the rotating reel 40 corresponding to the operated stop switch 50 is stopped. make it stop.

In addition, when stopping the rotating reel 40, the reel control means 130 can move the symbols in the rotational direction by a maximum of 4 frames with a maximum of 4 frames based on the symbol display position when the stop operation is performed, and then stop the rotating reels 40. With such control, when the lottery result of the winning lottery means 110 is a "lose", kick-off control is performed so that the symbols on the three rotating reels 40 do not align in any winning manner. In addition, when the lottery result does not match a predetermined winning combination, pull-in control is performed so that the symbols on the three rotating reels 40 are as close to the winning pattern as possible according to the winning combination.

Such kick-off control and pull-in control are calculated and executed based on the result of the winning lottery by the winning lottery means 110, the operation timing of the stop switch 50, the priority order of the stop position, etc. For example, when winning two or more types of roles at the same time, pull-in control is performed so that the symbol combination corresponding to the higher-priority role can be displayed on the active line according to the priority order associated with each role. .

In addition, in the case of winning a press order minor combination described later, if each stop switch 50 is operated in the correct press order, the symbols related to the press order minor combination will be displayed regardless of the timing of the stop operation. Draw it onto the active line and win the small combination in the push order. On the other hand, if each stop switch 50 is operated in a pressing order other than the correct pressing order, the symbols related to the pressing order minor combination will not be aligned on the active line, and the pressing order minor combination will not win. Control as follows.

(Winner determination means 140)
The prize determining means 140 is for determining whether a prize has been won or not based on the display mode when the three rotating reels 40 are stopped by operating the stop switch 50. Specifically, when all the rotating reels 40 stop rotating, it is determined that a winning combination corresponding to the symbol arrangement has been won, provided that a predetermined symbol arrangement is aligned on any valid winning line. do. If the winning is accompanied by a medal payout, a payout winning signal is output to the hopper unit 65 (or the medals are added to the credits instead of being paid out). Further, if the winning is to cause a change in the game state, the game state control means 100 is notified and the game state is changed. Furthermore, when the replay combination wins, automatic bet processing is performed so that the next game can be started without newly inserting game medals.

(Hopper control means 150)
The hopper control means 150 operates the hopper unit 65 based on the payout winning signal from the winning determining means 140, the operation signal of the settlement switch 17, etc., and controls the payout of medals. In addition, when winning is accompanied by a medal payout, the payout medals may be automatically stored electronically as credits, and only the payout amount exceeding the allowable number of credits may be paid out from the hopper unit 65.

(Production control means 200)
The presentation control means 200 is for controlling the operation of the presentation section 66 such as the image display section 67, the lamp 68, and the speaker 69. The effect control means 200 performs effects such as prize winning notification and press order notification based on the effect data stored in the ROM.

Note that the press order notification is to notify the operating order of the stop switch 50 that can win the press order minor win when a press order minor win to be described later is won. This pressing order notification is performed, for example, by displaying the order of operations on the image display section 67, notifying the stop switch 50 to be operated by voice from the speaker 69, or lighting up the stop switch 50 to be operated. .

(Press order notification control means 210)
The press order notification control means 210 is for controlling press order notification in an advantageous section to be described later. Specifically, when a press order minor winning combination is won, the press order notification control means 210 acquires the correct pressing order (operation order of the stop switch 50) for winning the press order minor winning combination, Select an effect to notify the press order of the correct answer. The effect selected by the press order notification control means 210 is notified to the effect control means 200 and executed, thereby executing the press order notification.

Note that the press order minor winning combination is a minor winning combination or a replay winning combination that is controlled so that winning symbols are aligned when the stop switch 50 is operated in a predetermined pressing order. If the push order is not reported, it is difficult to know which push order minor winning combination you have won, and you also do not know the correct push order, making it difficult to aim for the push order minor winning combination and win a prize. On the other hand, when the correct pressing order is notified, by operating the stop switch 50 according to the pressing order notification, it is possible to easily win the pressing order minor combination.

The press order notification control means 210 controls the press order notification to be performed only during a specific game (ART or AT) regarding some or all of the press order minor combinations. For this reason, during a specific game, it is easier to win a prize with a press order minor combination, while during a non-specific game, it is difficult to win a press order minor combination.

(Setting means 220)
The setting means 220 is for setting a set value from among a plurality of set values having different degrees of advantage to the player. This set value can be changed by operating a switch provided inside the locked housing 11, and can be changed by the manager of the hall in which the slot machine 10 is installed before the opening of the hall or after the opening of the hall. It will be preset after completion. Although not shown, a different combination drawing table 120 is provided for each setting value, and by using the combination drawing table 120 according to the setting value in the combination drawing, the payout rate of medals changes according to the setting value. It has become. In this embodiment, the set value is comprised of six levels from 1 to 6, with 6 being the highest payout rate, and decreasing values in the order of 5, 4, 3, 2, and 1, the lower the payout rate. In terms of payout rate, when 6 is set as the setting value, the player has the highest gaming advantage, and as the value decreases in the order of 5, 4, 3, 2, and 1, the gaming advantage increases. becomes lower. Note that in this embodiment, the set value is set to six levels, but the set value is not limited to this, and may be set to five levels or less.

(Specific game control means 230)
The specific game control means 230 is for controlling the execution of a specific game. A specific game is a game in which an instruction function is activated to display an operation mode advantageous to the player by activating the push order notification control means 210, and includes ART (assist replay time) and AT (assist time). It is a game called

This specific game control means 230 executes a specific game lottery when a predetermined specific game lottery trigger role is won in a game during an advantageous section to be described later, and controls to start a specific game when a specific game lottery is won. Execute.

The specific game lottery by the specific game control means 230 is performed, for example, by extracting random numbers generated by the random number generating means at the timing of operation of the start switch 30, and comparing the extracted random numbers with a specific game lottery table. In the specific game lottery table, each random number that can be extracted is assigned a "win" or "lose", so by comparing the random numbers with the specific game lottery table, you can determine whether it is a "win" or "lose". be able to.

In this embodiment, the specific game lottery triggering combination is "Watermelon", and as shown in FIG. 5, the RT3 state (during the RB game) does not win this specific game lottery triggering combination (watermelon). For this reason, the specific game lottery is not executed during the RB game, and the specific game cannot be started. On the other hand, in the RT0 state, RT1 state, and RT2 state, it is possible to win the specific game lottery trigger (watermelon), so the specific game lottery can be executed and the specific game can be started.

The specific game started by winning the specific game lottery continues until the number of specific game games awarded is exhausted. When the given number of specific game games is exhausted, the specific game control means 230 ends the specific game.

(Game section control means 240)
The game section control means 240 is for controlling the game section. The slot machine 10 according to the present embodiment includes, as game sections, a normal section in which the order in which the stop switches 50 are pressed is not reported, and an advantageous section in which the order in which the stop switches 50 are pressed is notified.

The normal section is a game section in which it is not possible to assist in winning the winning combination. Specifically, this is a game section in which the push order notification by the push order notification control means 210 is not possible. In this game section, the above-mentioned specific game cannot be executed.

Further, the advantageous section is a game section in which it is possible to assist in winning a winning combination. Specifically, this is a game section in which push order notification can be made by the push order notification control means 210. In this game section, it is possible to execute the above-mentioned specific games (in other words, during a specific game, it is always an advantageous section. However, during a non-specific game, it may be an advantageous section or a normal section) .

This gaming section control means 240 executes control to shift the gaming section to the advantageous section when a predetermined advantageous section shift opportunity is achieved in the normal section. In this embodiment, the trigger for moving to an advantageous section is winning a predetermined advantageous section transfer combination, and all winning combinations are set as the predetermined advantageous section transfer combination. Therefore, if you win some kind of winning combination (not a losing winning result), it is set to move to the advantageous section.

This advantageous section continues until a predetermined number of advantageous section games (for example, 1500 games) is played or a predetermined increased number of coins (for example, 2400 coins) is exceeded. Furthermore, as will be explained in detail later, this advantageous section also ends when both the specific game and zone transition are achieved. When the advantageous section ends, the game section shifts to the normal section.

(Mode management means 250)
The mode management means 250 is for managing a plurality of modes in which the probability of winning a specific game lottery is different. In this embodiment, as shown in FIG. 6, six modes are provided: "Mode A", "Mode B", "Mode C", "Mode D", "Mode E", and "Heaven Mode". These modes are "Mode A"<"ModeB"<"ModeC"<"ModeD"<
The winning probability of the specific game lottery is set to gradually increase in the order of "Mode E"<"HeavenMode".

Specifically, as shown in FIG. 11, when a specific game lottery is executed in "Mode A", the probability of winning is 28/256, and when a specific game lottery is executed in "Mode B", the probability of winning is 28/256. If executed, the probability of winning is 32/256, and if the specific game lottery is executed in "Mode C", the probability of winning is 42/256. If a specific game lottery is executed in "Mode D", the probability of winning is 64/256, and if a specific game lottery is executed in "Mode E", the probability of winning is 128/256. When a specific game lottery is executed in "heaven mode", the probability of winning is 240/256.

These modes are changed in stages from when the BB game starts to when it ends. That is, "Mode A" → "Mode B" → "Mode C" → "Mode D"
”→“Mode E”→“Heaven Mode”. By shifting the mode in stages in this manner, the probability of winning the specific game lottery gradually increases as the BB game is played.

Note that the mode transition stage is not limited to one stage, and may be two or more stages. For example, it is possible to suddenly shift from "Mode A" to "Mode C" or higher without passing through "Mode B".

The mode management means 250 according to the present embodiment determines which mode to transition to when transitioning to an advantageous section during a BB game. Specifically, the mode management means 250 executes a mode change lottery when the vehicle shifts to an advantageous section, and determines the mode based on this mode change lottery.

The lottery probability of this mode transition lottery is determined by the zone when the mode transition lottery is executed. A zone is a range divided by the number of sheets remaining up to the specified number (300 sheets) of the BB game, and the mode management means 250 according to the present embodiment divides the remaining number of sheets up to the specified number by 6 as shown in FIG. It is divided into two zones and managed.

That is, in this embodiment, as shown in FIG. corresponds to the above mode in a one-to-one relationship. That is, "Zone 1" corresponds to "Mode A", "Zone 2" corresponds to "Mode B", "Zone 3" corresponds to "Mode C", and "Zone 4" corresponds to "Mode D". "Zone 5" corresponds to "Mode E",
"Zone 6" corresponds to "Heaven Mode".

Further, the remaining number of cards up to a specified number is assigned to each zone, so that the remaining cards belong to any one zone during the BB game. In this embodiment, if the number of coins remaining up to the specified number of BB games is 250 or more (that is, the number of acquired coins during the BB game is 50 or less), it belongs to "Zone 1", and the remaining number of coins up to the specified number is If the number of coins obtained during the BB game is 200 to 249 (i.e., the number of coins obtained during the BB game is 51 to 100), it belongs to "Zone 2". 101 to 150), it belongs to "Zone 3", and if the remaining number of coins to the specified number is 100 to 149 (i.e., the number of coins obtained during the BB game is 151 to 200), it belongs to "Zone 4". , if the remaining number of coins up to the specified number is 50 to 99 (i.e., the number of acquired coins during the BB game is 201 to 250), it belongs to "Zone 5", and the remaining number of cards up to the specified number is 49 or less (i.e., If the number of coins obtained during the BB game is 251 or more), it belongs to "Zone 6".

Then, the mode management means 250 according to the present embodiment identifies the current zone by referring to the remaining number of tickets up to the specified number at the time of transition to the advantageous section, and uses the mode transition lottery table associated with that zone. and execute the mode transition lottery. For example, if the number of tickets remaining up to the specified number when moving to the advantageous zone is 250 or more, the current zone is "Zone 1" and the mode transition lottery table associated with "Zone 1" is used. Execute mode transition lottery.

The mode transition lottery table is provided in a one-to-one ratio corresponding to each zone, and each has a different lottery probability. For this reason, the mode transition lottery is executed with different lottery probabilities depending on the zone when the zone shifts to the advantageous section.

FIG. 7 is a diagram showing the lottery probability of the mode transition lottery. As shown in this figure, the mode transition lottery is configured so that only a mode higher than the mode corresponding to the current zone (a mode with a higher probability of winning a specific game lottery than the current mode) is selected.

Specifically, if a non-BB game (a game that is not a BB game) is moved to an advantageous section and a mode transition lottery is executed, the current zone does not exist and the mode corresponding to the current zone also does not exist. Since none exists, all modes are selectable. When a mode transition lottery is executed in a non-BB game, "Mode A" is selected with a probability of approximately 16.7%, "Mode B" is selected with a probability of approximately 16.7%, and the probability of "Mode B" is selected with approximately 16.7%. "Mode C" is selected with a probability of about 16.7%, "Mode D" is selected with a probability of about 16.7%, "Mode E" is selected with a probability of about 16.7%, and a probability of about 16.7% is selected. ``Heaven Mode'' is selected.

In addition, if a mode transition lottery is executed after moving to an advantageous section in "Zone 1", since the mode corresponding to the current zone is "Mode A", "Mode A" including "Mode A"
” (all modes) can be selected. If the mode transition lottery is executed in "Zone 1", "Mode A" will be selected with a probability of 80.0%, "Mode B" will be selected with a probability of 10.0%, and probability of 5.0%. "Mode C" is selected with a probability of 3.0%, "Mode D" is selected with a probability of 1.0%, "Mode E" is selected with a probability of 1.0%, and "Heaven Mode" is selected with a probability of 1.0%. is selected.

In addition, if the mode transition lottery is executed after moving to an advantageous section in "Zone 2", since the mode corresponding to the current zone is "Mode B", "Mode B" including "Mode B"
” (“Mode B,” “Mode C,” “Mode D,” “Mode E,” and “Heaven Mode”) can be selected. If the mode transition lottery is executed in "Zone 2", 50
．． "Mode B" is selected with a probability of 0%, "Mode C" is selected with a probability of 15.0%, "Mode D" is selected with a probability of 7.5%, and "Mode D" is selected with a probability of 7.5%. "Mode E" is selected, and "Heaven Mode" is selected with a probability of 20.0%.

In addition, if the mode transition lottery is executed after moving to an advantageous section in "Zone 3", the mode corresponding to the current zone is "Mode C", so "Mode C" including "Mode C"
” (“Mode C,” “Mode D,” “Mode E,” and “Heaven Mode”) can be selected. When the mode transition lottery is executed in "Zone 3", "Mode C" is selected with a probability of 50.0%, "Mode D" is selected with a probability of 12.5%, and "Mode D" is selected with a probability of 12.5%. ``Mode E'' is selected, and ``Heaven Mode'' is selected with a probability of 25.0%.

In addition, if the mode transition lottery is executed after moving to an advantageous section in "Zone 4", the mode corresponding to the current zone is "Mode D", so "Mode D" including "Mode D"
” (“Mode D,” “Mode E,” and “Heaven Mode”) can be selected. If the mode transition lottery is executed in “Zone 4”, there is a 50.0% probability that “Mode D
" is selected, "Mode E" is selected with a probability of 20.0%, and "Heaven Mode" is selected with a probability of 30.0%.

In addition, if the mode transition lottery is executed after moving to an advantageous section in "Zone 5", the mode corresponding to the current zone is "Mode E", so "Mode E" including "Mode E"
” (“Mode E” and “Heaven Mode”) can be selected. When the mode transition lottery is executed in "Zone 5", "Mode E" is selected with a probability of 50.0%, and "Heaven Mode" is selected with a probability of 50.0%.

In addition, if the mode transition lottery is executed after moving to an advantageous section in "Zone 6", the mode corresponding to the current zone is "Heaven Mode", so "Heaven Mode" including "Heaven Mode" A higher level mode (only "heaven mode") can be selected. "Zone 6
”, if the mode transition lottery is executed, “Heaven Mode” will be selected with a 100.0% probability.

Therefore, as shown in Figure 8, as the number of coins acquired in the BB game accumulates and the number of coins remaining until the specified number decreases, the probability of transitioning to a more advantageous mode gradually increases. Accordingly, the probability of starting a specific game is also improved.

Note that the mode transition lottery as described above is executed at the start of the advantageous section. In other words, the mode transition is performed at the time of transition to the advantageous section. Therefore, in order to shift to an advantageous mode, it is necessary to once complete the advantageous section, and then shift to the advantageous section again to execute the mode change lottery.

In the present embodiment, by adjusting the timing at which the advantageous section ends, the system is configured to always shift to an advantageous mode in the mode transition lottery at the time of transition to the advantageous section.

Specifically, the game section control means 240 according to the present embodiment determines whether (1) a specific game has ended while staying in a zone next to the zone corresponding to the current mode, or (2) a specific game. After the end of the game, the advantageous section is ended on the condition that the zone has moved to the next zone corresponding to the current mode. The order of the zones is cyclical: "Zone 1" → "Zone 2" → "Zone 3" → "Zone 4" → "Zone 5" → "Zone 6" → "Zone 1". The zone after "Zone 1" is "Zone 2", the zone after "Zone 2" is "Zone 3", and the zone after "Zone 3" is "Zone 4".
”, the zone after “Zone 4” is “Zone 5”, the zone after “Zone 5” is “Zone 6”, and the zone after “Zone 6” is “Zone 1”. be.

In this way, by configuring the advantageous section to end in the zone next to the zone corresponding to the current mode, the mode will always be in an advantageous mode in the mode transition lottery when the next advantageous section is entered, except when staying in heaven mode. It is configured to move to For example, if the current mode is "Mode A" and the current zone is "Zone 1", until the zone (Zone 1) corresponding to the current mode (Mode A) ends (BB game The advantageous section does not end until the number of sheets remaining up to the specified number is less than 250 sheets. As a result, when shifting to the advantageous section again after the end of the advantageous section, the player always moves to the next zone (Zone 2), so that in the mode change lottery, the player can only win in a mode higher than the current mode. For this reason, when moving to an advantageous section, the mode is always shifted to a higher mode than the current mode, unless the user is staying in the highest heaven mode.

In addition, since the end of the specific game is a condition for ending the advantageous section, even if you move to the next zone of the zone corresponding to the current mode, the advantageous section will not end if you have not performed the specific game (mode change (also not performed).

In addition, if it is difficult to win a specific game lottery, the zone next to the zone corresponding to the current mode may end before the specific game ends. In this case, the advantageous section does not end (no zone transition occurs) until the BB game is finished once. For example, if the current mode is "Mode A" and you exit "Zone 2" without executing a specific game (if the zone next to the zone corresponding to the current mode ends) ), the advantageous section cannot be completed until the next "Zone 2" starts (no mode transition occurs). Then, the next timing to start "Zone 2" is when you start the BB game again after finishing the BB game and move to Zone 2 (when the number of remaining cards to the specified number is 249 or less) Therefore, the advantageous section does not end (zone transition does not occur) until the BB game ends. In this way, in this embodiment, the mode can be maintained across BB games.

(About the winning role)
The winning lottery means 110 according to this embodiment stores the lottery result in the RAM as an internal flag. Specifically, when any of the winning combinations is won as a result of the drawing by the winning drawing means 110, a winning flag corresponding to the winning is established. Then, the winning combination associated with the established winning flag is recognized as a winning winning combination.

Note that the winning flag related to the bonus combination is carried over to the next and subsequent games even if no prize is won in the game in which the winning flag is established. In other words, the right to win the winning combination is maintained until the prize is won. On the other hand, winning flags related to other winning combinations are reset if no prize is won in the game in which the winning flag is established, and are not carried over to subsequent games.

As shown in FIG. 5, the slot machine 10 according to the present embodiment has winning combinations such as "Replay", "BB", "RB", "Press Order Bell", "Common Bell", "Watermelon", "RB Middle Bell", and "Single-card". ”. Note that these are part of the winning combinations, and other winning combinations may also be provided.

Among these, "Replay" is a replay role. When the "replay" is won, the stop control of the rotating reel 40 that draws in the "replay" is executed, and the "replay" is won. If you win a "replay", you will be able to play the next game without inserting new medals.

"BB" is the role of BB. When "BB" is hit, the rotating reels 40 are allowed to be stopped so as to achieve a winning pattern corresponding to "BB". When these symbols are displayed and the player wins "BB", the BB game starts from the next game.

"RB" is the role of RB. When "RB" is hit, the rotating reels 40 are allowed to be stopped so as to achieve a winning pattern corresponding to "RB". When these symbols are displayed and the player wins "RB", the RB game starts from the next game.

``Oshijun Bell'' is a small role. This “push order bell” is a press order small combination whose winning mode changes depending on the press order of the stop switch 50. When the stop switches 50 are operated in the correct order, stop control of the rotating reels 40 is permitted so as to form a winning mode corresponding to the "press order bell". When these symbols are displayed and the "push order bell" is won, a predetermined number of medals (15 medals) are paid out. Note that if the stop switches 50 are not operated in the correct order, kick-off control is executed so as not to win the "push order bell".

"Common Bell" is a small role. When the "common bell" is hit, the rotating reels 40 are allowed to be stopped so as to achieve a winning pattern corresponding to the "common bell". When these symbols are displayed and the "common bell" is won, a predetermined number (3) of medals are paid out.

``Watermelon'' is a small role. When a "watermelon" is won, the rotating reels 40 are allowed to be stopped so that a winning mode corresponding to the "watermelon" is achieved. When these symbols are displayed and a "watermelon" is won, a predetermined number (3) of medals are paid out.

"RB Middle Bell" is a small role. When the "RB middle bell" is hit, the rotating reels 40 are allowed to be stopped so as to form a winning pattern corresponding to the "RB middle bell". When these symbols are displayed and the player wins the "RB Medium Bell", a predetermined number of medals (15 medals) are paid out.

A "one piece role" is a small role. When a "one-card winning combination" is won, the rotating reels 40 are allowed to be stopped so as to form a winning pattern corresponding to the "one-card winning combination." When these symbols are displayed and a "one-card winning combination" is won, a predetermined number of medals (one medal) are paid out.
Regarding these winning combinations, the probability of winning as shown in FIG. 5 is set in each gaming state.

That is, in the RT0 state, the winning probability of replay is 1/7.3, the winning probability of BB is 1/2.6, the winning probability of RB is 0, and the winning probability of pressing order bell is 1/2.9. The probability of winning a bell is set to 1/9.4, the probability of winning a watermelon is 1/32, the probability of winning a bell in RB is set to 0, and the probability of winning a one-card combination is set to 0.

In addition, in the RT1 state, the winning probability of replay is 1/7.3, the winning probability of BB is 0, the winning probability of RB is 1/1.9, and the winning probability of pressing order bell is 1/2.9. The probability of winning a bell is set to 1/9.4, the probability of winning a watermelon is 1/32, the probability of winning a bell in RB is set to 0, and the probability of winning a one-card combination is set to 0.

In addition, in the RT2 state, the probability of winning the replay is 0, the probability of winning BB is 0, the probability of winning RB is 0, the probability of winning the push order bell is 1/2.9, and the probability of winning the common bell is 1.
/9.4, the probability of winning a watermelon is set to 1/32, the probability of winning a bell in RB is set to 0, and the probability of winning a 1-card combination is set to 0.

In addition, in the RT3 state, the probability of winning the replay is 0, the probability of winning BB is 0, the probability of winning RB is 0, the probability of winning the push order bell is 0, the probability of winning the common bell is 1/7.3, and the probability of winning the watermelon is 0. The probability of winning is set to 0, the probability of winning of Bell in RB is set to 1/17.6, and the probability of winning of 1-card combination is set to 1/3.5.

Furthermore, in the RT0 state, the probability of winning the BB combination is set to be very high. Specifically, the probability of winning the BB combination (1/2.6) is set higher than the probability of winning the replay combination (1/7.3). Therefore, in the RT0 state, it is easy to win the BB role, and the BB game can be started immediately.

In addition, in the RT0 state, RT1 state, and RT2 state, it is possible to win the "push order bell" which is a push order minor combination, so it is possible to execute a specific game by notification of the push order. On the other hand, in the RT3 state, the push order minor combination "Push Order Bell" is not hit, so even if a specific game is being executed, the push order notification is not executed.

(About the game flow)
Next, the flow when a player actually plays a game on the slot machine 10 will be explained with reference to FIG. 9.
First, as shown in step S1 in FIG. 9, the player starts playing the game in the RT0 state. In this RT0 state, the player aims to win the BB combination, but as described above, the player easily wins the BB combination.

If you win the BB combination, as shown in step S2, you will be in a state where you have internally won the BB combination. Here, the player aims to win the BB winning combination. Specifically, the stop switch 50 is operated at a good timing so that the winning symbols of the BB combination are aligned on the active line.

When the BB winning combination is won, the state shifts to the RT1 state as shown in step S3. In this RT1 state, the player executes a game while expecting the start of a specific game.

If the player wins the RB role in the RT1 state, the game moves to the RT2 state as shown in step S4. In this RT2 state, the player executes a game while expecting the start of a specific game. However, if the player wins the RB prize and moves to the RT3 state (starts the RB game), the number of medals earned will decrease and he will not be able to start a specific game, so the player can play the game while avoiding winning the RB prize. I do. Specifically, the stop switch 50 is operated in a timely manner so that the winning symbols of the RB combination do not line up on the active line.
When the BB game ends, the state returns to RT0 and the above game flow is repeated.

(About mode transition flow)
Next, mode transition during the BB game will be explained with reference to FIG. 10.
First, as shown in (1) of FIG. 10, the BB game starts. Since the number of acquired coins is 0 at the start of the BB game, the remaining number of coins up to the specified number of BB games is 250 or more. Therefore, the zone becomes "Zone 1".

Further, as shown in (2), when the BB game shifts to an advantageous section before and after the start and a mode transition lottery is executed, the mode shifts to the mode determined by the mode transition lottery. Here, it is assumed that "Mode A" is applied and the mode is shifted to "Mode A". In this case, the player plays the game in mode A while expecting to win the specific game lottery.

After that, as shown in (3), it is assumed that the specific game lottery is won and the specific game is executed. If the zone when the specific game ends is "Zone 2", the specific game ends while staying in the next zone (Zone 2) after the zone (Zone 1) corresponding to the current mode (Mode A). Therefore, the conditions for ending the advantageous section are met. Therefore, the advantageous section ends and shifts to the normal section.

After shifting to the normal section, as shown in (4), the hand immediately plays the advantageous section transition role. In the mode transition lottery at this time, let's assume that "Mode C" is selected, and "Mode C" is selected.
”. In this case, the player plays the game in mode C while expecting to win the specific game lottery.

Thereafter, as shown in (5), it is assumed that the specific game lottery is won and the specific game is executed. If the zone when the specific game ends is "Zone 3", the advantageous section ends because you are not staying in the next zone (Zone 4) after the zone (Zone 3) corresponding to the current mode (Mode C). Condition is not met. Therefore, the advantageous section does not end at this point.

However, as shown in (6), if the number of acquired coins is accumulated by playing BB games and the number of coins remaining until the specified number of BB games decreases, and the state moves to "Zone 4", the specified game After the end, the zone (Zone 3) corresponding to the current mode (Mode C) has been moved to the next zone (Zone 4), so the conditions for ending the advantageous section are satisfied. Therefore, the advantageous section ends and shifts to the normal section.

After shifting to the normal section, as shown in (7), the hand immediately plays an advantageous section transition role. In the mode transition lottery at this time, here we assume that "Mode E" is selected, and "Mode E" is selected.
”. In this case, the player plays the game in mode E while expecting to win the specific game lottery.

Thereafter, as shown in (8), it is assumed that the specific game lottery is won and the specific game is executed. If the zone when the specific game ends is "Zone 6", the specific game ends while staying in the next zone (Zone 6) after the zone (Zone 5) corresponding to the current mode (Mode E). Therefore, the conditions for ending the advantageous section are met. Therefore, the advantageous section ends and shifts to the normal section.

After shifting to the normal section, as shown in (9), the hand immediately plays the advantageous section transition role. In the mode transition lottery at this time, the player will definitely win the "heaven mode" and will be transferred to the "heaven mode." In this case, the player plays the game in this heaven mode while expecting to win the specific game lottery.

The heaven mode according to the present embodiment is configured to perform a specific game continuation lottery when a specific game lottery is won. If the specific game continuation lottery is not won, a process of ending the heaven mode and resetting the mode is executed. Specifically, the game waits until it moves to Zone 1 (after the end of a specific game, until it moves to the next zone (Zone 1) of the zone (Zone 6) corresponding to the current mode (Heaven mode)). The advantageous section is ended, and the mode transition lottery is thereby executed in the initial state.

(summary)
As described above, in the present embodiment, the mode management means 250 determines the mode by referring to the remaining number of sheets up to the specified number when the BB game shifts to an advantageous section. Therefore, even if the advantageous section ends, the number of sheets remaining up to the specified number will have changed at the time of the next transition to the advantageous section, so it can be expected that the mode will shift to an advantageous mode. For example, if an advantageous period ends during a BB game, and then shifts to an advantageous period again during the same BB game, the number of remaining cards up to the specified number in the BB game has decreased, so the mode will be changed to a different mode than before. will be transferred. In this way, even if the advantageous section ends and you move to the normal section, you can expect to switch to a mode that is more advantageous than the mode you were in at the end of the previous advantageous section, so when the advantageous section ends ( Even when the game shifts to the normal section), the player's sense of anticipation can be maintained.

Further, the mode management means 250 executes a mode transition lottery for determining the mode when the game shifts to an advantageous section during the BB game. With this configuration, the mode to which the game will be transferred is determined at random, making it possible to keep the player's heart racing. Even if the player counts the number of coins he or she has won in the BB game, he or she cannot completely predict the mode to which the player will transition, resulting in an unpredictable game development.

Further, the mode management means 250 manages the remaining number of tickets up to the specified number by dividing them into a plurality of zones, and executes a mode transition lottery with a different lottery probability for each zone. With this configuration, the drawing probability of the mode transition drawing can be varied in accordance with the progress of the BB game.

Furthermore, the mode management means 250 determines modes corresponding to zones in stages, and is configured such that only modes equal to or higher than the mode corresponding to the current zone are selected in the mode transition lottery. With this configuration, it is possible to realize a gaming machine in which the probability of winning the lottery increases step by step as the BB game progresses.

Furthermore, the game section control means 240 does not end the advantageous section until the zone corresponding to the current mode ends. According to such a configuration, in the mode transition lottery when moving to the next advantageous section after completing the advantageous section, it is possible to configure the mode to shift to a mode more advantageous than the current mode.

In addition, in the above-described embodiment, the mode management means 250 determines the mode by mode transition lottery, but the present invention is not limited to this. For example, it may be possible to forcibly shift to a mode corresponding to the zone at the time of transition to an advantageous section.

Further, in the above-described embodiment, the lottery probability of the mode transition lottery is set so that the mode increases in stages, but the present invention is not limited to this. For example, a mode may be adopted in which a zone where the mode increases (or where the probability of the mode increasing is high) and a zone where the mode decreases (or where the probability that the mode decreases is high) appear alternately. For example, if you move to an advantageous zone in "Zone 1", "Zone 3", or "Zone 5", a mode transition lottery will be executed in which the mode will increase (or there is a high probability that it will increase), but "Zone 2" or "Zone 4" ” If the mode transitions to an advantageous section in “Zone 6,” a mode transition lottery may be performed in which the mode will go down (or there is a high probability that the mode will go down).
