Description

This invention relates to a gaming machine.

There are known gaming machines capable of performing so-called "promotion sequences" (see, for example, Patent Document 1 below).

Japanese Patent Publication No. 2021-168998

The problem that this invention aims to solve is to provide a gaming machine that can perform promotion sequences in an easy-to-understand manner.

The present invention, developed to solve the above problems, is a gaming machine that includes multiple types of jackpots, including a special jackpot, which can be won when the win/failure lottery result is a win. The machine is capable of executing an upgrade sequence as part of the winning spin sequence, which occurs from the start of the spinning of multiple decorative symbols until the symbols stop in a manner indicating a win. The upgrade sequence can be a special upgrade sequence that transitions from a state where it is uncertain whether the special jackpot can be won to a state where it is indicated that the special jackpot can be won. The machine is characterized in that a special image representing a predetermined performance element is displayed during the special upgrade sequence and during the special jackpot.

The gaming machine according to this invention is capable of performing an easily understandable promotion animation.

The embodiments of the pachinko game machine 1 (hereinafter simply referred to as the game machine) according to the present invention will be described in detail below with reference to the drawings. Unless otherwise specified, the images in the following description include not only still images but also videos. Furthermore, unless otherwise specified, the following description assumes that normal gameplay (gameplay as intended) is taking place. Also, when it is stated that "a game ball enters (wins) XX," it strictly means that a sensor installed in XX has detected the game ball entering.

1) Basic Configuration of the Gaming Machine The overall configuration of the gaming machine 1 (see Figure 1) will be briefly explained. The gaming machine 1 is equipped with a game board 90. The game board 90 is formed from a nearly square piece of plywood, and guide rails 903 that form a passage for guiding the game balls launched by the operation of the launching device 908 (launching handle) to the game area 902 are provided in a roughly arc shape. The game area 902 is equipped with a starting area 904, a big prize area 906, an out opening 907, and so on.

The display area 911 of the display device 91 is visible through the opening 901 formed in the game board 90. In some figures, the shape of the display area 911 that is exposed and not covered by the game board 90 is simplified (shown as a rectangle), but the size and shape of this portion can be changed as appropriate.

Furthermore, the game area 902 is provided with multiple game pins, which act as obstacles that alter the flow of the game balls upon collision. The game balls flowing through the game area 902 change their flow pattern in various ways depending on the conditions of collision with the game pins.

In this type of gaming machine 1, game balls are launched towards the game area 902 by operating the launching device 908. When game balls flowing down the game area 902 enter prize areas such as the starting area 904 or the big prize area 906, a predetermined number of prize balls are dispensed by the payout device.

2) Gameplay (Specifications)
2-1) Winning/Losing Draw (Special Design Draw)
When a game ball enters the starting area 904, a numerical value (sometimes referred to as win/loss lottery information) is obtained from a random number source. A win/loss lottery (generally referred to as a special symbol lottery, etc.) is performed using this numerical value. Basically, as with well-known gaming machines, the win/loss lottery result is derived by comparing this numerical value with a predetermined judgment value (win/loss lottery table). This numerical value is also used to determine what kind of in-game effects (described later) will be performed.

In this embodiment, the starting area 904 is provided as a first starting area 904a and a second starting area 904b located at a different position from the first starting area 904a (see Figure 1). When a game ball enters the first starting area 904a, first win/loss lottery information is acquired, and based on this, the first win/loss lottery (special drawing 1 lottery) is performed. When a game ball enters the second starting area 904b, second win/loss lottery information is acquired, and based on this, the second win/loss lottery (special drawing 2 lottery) is performed. The first starting area 904a is the area into which the game ball enters when the game ball is launched so as to flow down the left side of the game area 902 (left side of the display area 911) (so-called "left-handed shooting"). The second starting area 904b is the area into which the game ball enters when it is launched so as to flow downwards to the right of the game area 902 (to the right of the display area 911) (so-called "right-handed shooting"). In this embodiment, the game ball does not enter the first starting area 904a when "right-handed shooting" is performed, and the game ball does not enter the second starting area 904b when "left-handed shooting" is performed.

In this embodiment, the result of the draw is either a "minor win" or a "loss." That is, if the draw is a "win," it is always a "minor win," and there are no "big wins." However, as will be described later, unless an anomaly occurs, all minor wins will lead to winning a big win, so in effect, a minor win equals a big win. Therefore, in the following explanation, "big win" in terms of big win probability, big win, etc. strictly refers to a minor win. Various effects and presentations are designed to make winning a minor win seem like winning a big win. Incidentally, a gaming machine that allows you to win a big win via a minor win in this way is called a "Type 2" gaming machine. As stated above, in this embodiment, the result of the draw is not a big win and you cannot win a big win (so-called direct wins do not occur), so it does not have the gameplay characteristics of a "Type 1" game (it is not a "Type 1 and Type 2 mixed" gaming machine either). However, with the exception of configurations that can only be achieved with a "Type 2" machine, the technical matters described below can also be applied to "Type 1" gaming machines and "Type 1 & 2 mixed" gaming machines.

In this embodiment, the probability of a minor win (effectively the probability of a major win) in the first draw is 1/319 (anything else is a loss). Similarly, the probability of a minor win (effectively the probability of a major win) in the second draw is 1/47 (anything else is a loss). Therefore, the second draw is more advantageous for the player (a higher probability draw) than the first draw. As will be explained in detail later, the normal game state aims to win a major prize through the first draw, while the specific game state aims to win a major prize through the second draw. Therefore, the specific game state is more advantageous than the normal game state.

2-2) Winning Game If a jackpot is won, the jackpot game is executed. The jackpot game consists of one or more unit games (a game equivalent to one "round"; sometimes referred to as a "round" in the following explanation) in which the large prize area 906 (normally closed) is opened until a predetermined condition is met. One unit game ends (the large prize area 906 closes) when either the prize-winning condition (C game balls entering the large prize area 906) or the time condition (a predetermined amount of time elapses) is met. In this embodiment, C = 10 (this value of C is generally referred to as the "count"). In each unit game, if game balls are continuously launched toward the large prize area 906, the prize-winning condition will almost certainly be met before the time condition is met. In other words, if the game is played as instructed, at least 10 game balls will be awarded in one unit game. In this embodiment, when a game ball enters the big prize area, the payout (number of prize balls) is 15, so at least 150 prize balls can be obtained in one unit game (this number increases when so-called over-winning occurs). The more unit games (number of rounds) included in a big win game, the greater the player's profit (expected value of profit) obtained in that big win game. In this embodiment, the big prize area 906 is located to the right of the game area 902 (see Figure 1), and the player plays the game so that the game ball enters to the right of the game area 902 (so-called "right-handed play").

As described above, in this embodiment, a big win can be obtained via a small win. When a small win is achieved, a small win game is executed. In the small win game, the big prize area 906 is opened, and the bonus area 10 (see Figure 2) provided within the big prize area 906 is also opened. The letter "V" is attached near the bonus area 10 (see Figures 1 and 2), and this "V" is used as wording to indicate the bonus area 10 to the player. The bonus area 10 is normally closed, but is temporarily opened when a small win is achieved. The big prize area 906 is provided with two exit areas, and a game ball that enters the big prize area 906 will pass through one of these two exit areas. One of these two exit areas is the bonus area 10 (see Figure 2). A sensor is provided in each of these exit areas, and a game ball that passes through either of these exit areas is treated as having entered the big prize area 906. In other words, a game ball that enters bonus area 10 also enters the grand prize area 906.

In this minor win game, the condition for winning a jackpot is for a game ball to enter the bonus area 10 (to win a jackpot, one game ball needs to enter the bonus area 10). In the following explanation, the entry of a game ball into the bonus area 10 may be referred to as a "V-win" ("V-win = jackpot win (jackpot confirmed)"). Note that the bonus area 10 may be located outside the jackpot area 906. A minor win game is considered a unit game equivalent to one round of the jackpot game won through it. For example, a 10-round jackpot (a jackpot where the unit game is executed 10 times) that follows a minor win means that the minor win game (a game in which the large prize area 906 and the bonus area 10 are opened) is the first round of the game, and the subsequent opening of the large prize area 906 as part of the jackpot game is executed as rounds 2 through 10 (if no game balls enter the bonus area 10, it is a so-called "puncture," and rounds 2 through 10 are not executed, ending with only the minor win game). The minor win game ends when at least one of the time condition and the prize condition (10 prizes in this embodiment) is met, similar to the unit games that make up the jackpot game. Since the prize condition will be met first if game balls are continuously launched, the same number of prize balls can be obtained in the minor win game as in a single unit game.

In this embodiment, during a minor win, the bonus area 10 is opened along with the major prize area 906, and the time is sufficient to allow the game ball to enter the bonus area 10. The bonus area 10 is located to the right of the game area 902, and in order to get the game ball into the bonus area 10, the player must shoot to the right. If the player continues to shoot to the right, the game ball will almost certainly enter the bonus area 10 (see Figure 2(b)). When a minor win is achieved, an instruction to shoot to the right is displayed in the display area 911 (see Figure 2(c)), so the player only needs to follow this instruction. Even if the player starts shooting to the right about 10 seconds after the instruction is given, the game ball will almost certainly enter the bonus area 10. Thus, when a minor win results in the execution of a minor win game, (unless an unexpected abnormality (such as a power outage or malfunction) occurs) the game ball will enter the bonus area 10 as long as the game is played as instructed. Therefore, in effect, "minor win = major win" (a minor win leads to a major win). In this embodiment, during unit games (from the second round onwards) that constitute a major win game other than the minor win game, the bonus area 10 is closed (see Figure 2(a)).

2-3) Decorative Patterns The result of the draw is indicated by decorative patterns 80 (see Figure 3) displayed in the display area 911. In this embodiment, three groups of decorative patterns 80g are set, each containing multiple types of decorative patterns 80. Specifically, these are the left decorative pattern group 80gL displayed on the left side of the display area 911, the right decorative pattern group 80gR displayed on the right side, and the middle decorative pattern group 80gC displayed between the left decorative pattern group 80gL and the right decorative pattern group 80gR. The draw result is indicated by a combination of three decorative patterns 80 selected and displayed from each decorative pattern group 80g. The performance from when the three decorative pattern groups 80g start to change until the change stops and the combination indicating the draw result is displayed is called the change performance (hereinafter sometimes simply referred to as "change" or "rotation"). Note that in some drawings, the illustration of the decorative patterns 80 is omitted. In this embodiment, decorative patterns 80 containing the same numbers are considered the same type (those containing different types of numbers are considered different types).

In this embodiment, when the draw result is a win (minor win), a winning combination consisting of three identical decorative symbols 80 is displayed. As described above, in this embodiment, a minor win is essentially equivalent to a major win, so the display of three identical decorative symbols 80 essentially indicates a major win. If the draw result is a loss, a combination that is not a winning combination (a losing combination) is displayed.

Although the explanation is omitted here, other symbols (separate symbols) besides the decorative symbol 80 may be displayed, and the winning/losing result may be indicated by these separate symbols. These separate symbols may be displayed as small symbols near the outer edge of the display area 911, or they may be displayed outside the display area 911 (e.g., as lighting patterns for lamps, etc., displayed outside the display area 911). However, ordinary players can enjoy the game by watching the decorative symbol 80 and the various effects performed in the display area 911 without being aware of the form of the separate symbols.

2-4) Reserve When a game ball enters the starting area 904 and new win/loss lottery information is acquired, if a variation performance corresponding to the previously acquired win/loss lottery information is being performed (in the case of variation of the decorative symbols 80), the newly acquired win/loss lottery information is stored as reserved information (reserved) in the storage means (not shown). In this embodiment, the maximum number of first reserved information (special symbol 1 reserved) acquired as first win/loss lottery information that can be stored is four, and the maximum number of second reserved information (special symbol 2 reserved) acquired as second win/loss lottery information that can be stored is four.

The reserved information stored in the memory means may be displayed in the display area 911 as a reserved symbol 70 (see Figure 3). In this embodiment, the reserved symbols 70 are divided into a reserved symbol 71 during reel spinning and a reserved symbol 72 before reel spinning. The reserved symbol 71 during reel spinning indicates the existence of win/loss lottery information for which the reel spinning animation for the corresponding win/loss lottery result has not yet started, but the notification of the win/loss lottery result has not been completed (the reel spinning animation has not ended). While this win/loss lottery information is not strictly considered reserved information, it is generally referred to as "the relevant reel spinning reserved information," and therefore the symbol indicating the existence of this win/loss lottery information is designated as the reserved symbol 71 during reel spinning. The reserved symbol 72 before reel spinning indicates the existence of win/loss lottery information (reserved information) for which the reel spinning animation for the corresponding win/loss lottery result has not yet started.

In this embodiment, when the game ball should be launched aiming at the first starting area 904a (a state where left-handed shooting is required; the normal game state will be described in detail later), a reserve symbol (Special Figure 1 Reserve) indicating the existence of the first win/fail lottery information (first reserve information) is displayed. When the game ball should be launched aiming at the second starting area 904b (a state where right-handed shooting is required; the specific game state will be described in detail later later), a reserve symbol (Special Figure 2 Reserve) indicating the existence of the second win/fail lottery information (second reserve information) is displayed. Note that in some drawings, the illustration of the reserve symbol 70 is omitted.

When both the first win/loss lottery information (first reserved information) and the second win/loss lottery information (second reserved information) are stored in the memory device, the in-game animation based on the second win/loss lottery information takes priority (the result of the second win/loss lottery is announced first), and the in-game animation based on the first win/loss lottery information is not started (the result of the first win/loss lottery is not announced) until the second win/loss lottery information stored in the memory device is gone. In other words, the gaming machine 1 according to this embodiment is what is known as "prioritizing the consumption of special feature 2 (reserved)."

2-5) Game State 2-5-1) Normal Game State and Specific Game State The game state in which a player aims to win a jackpot (by launching game balls aiming at the starting area 904) can be broadly divided into the normal game state and the specific game state (see Figure 4). Basically, the specific game state is more advantageous for the player than the normal game state because both the ease of winning a jackpot and the ease of getting game balls into the starting area 904 are better in the specific game state than in the normal game state.

The normal game state is one in which the player should aim to launch the game ball into the first starting area 904a (i.e., "left-handed shooting" should be performed). If the player "shoots to the right" in the normal game state, the player will not be able to enjoy the intended profit (the profit enjoyed will be significantly reduced compared to "left-handed shooting"). Therefore, if "right-handed shooting" is detected, the player will be advised to "shoot to the left." As mentioned above, the probability of winning the first win/loss lottery (minor win probability), which is performed on the condition that the game ball enters the first starting area 904a, is 1/319. Therefore, the normal game state can be said to be a game state in which the player aims to win the jackpot with a probability of 1/319.

On the other hand, the specific game state is a game state in which the player should aim to launch the game ball towards the second starting area 904b (i.e., "right-handed shooting" should be performed). If the player "shoots left-handed" in the specific game state, the player will not be able to enjoy the intended profit (the profit enjoyed will be significantly reduced compared to when "shooting right-handed" is performed). Therefore, if "left-handed shooting" is detected, the player will be warned to "shoot right-handed". As mentioned above, the probability of winning the second win/loss lottery, which is performed on the condition that the game ball enters the second starting area 904b, is 1/47. Therefore, the normal game state can be said to be a game state in which the player aims to win the jackpot with a probability of 1/47.

2-5-2) Opening/Closing Mode (with or without time-saving feature)
There are two opening/closing modes: a low opening/closing mode and a high opening/closing mode. The low opening/closing mode and the high opening/closing mode differ in how easily the second starting area 904b (see Figure 1) is opened. The second starting area 904b is an area that is normally closed (when closed, game balls cannot enter), and it is an area that is opened by winning the opening lottery (a lottery different from the win/loss lottery (special symbol lottery) that is executed when a game ball enters the starting area 904, and is generally called a normal lottery, normal symbol lottery, etc.) (this is the so-called "electric tuner (area)").

The opening lottery is performed based on a numerical value (opening lottery information) obtained when a game ball enters the normal area 905. In this embodiment, the normal area 905 is provided to the right of the game area 902 (see Figure 1). By shooting to the right, the game ball enters the normal area 905 relatively easily. The method for notifying the success or failure of the opening lottery is the same as in general gaming machines, so a detailed explanation is omitted. In this embodiment, the result is notified by the lighting pattern of a lamp located outside the display area 911 (the lighting pattern of this lamp corresponds to the "normal symbol"). If a game ball enters the normal area 905 while the notification of the opening lottery result is not yet complete (while the normal symbol is changing), the opening lottery information is stored in a storage means (not shown). In this embodiment, the maximum number of opening lottery information entries that can be stored is four (maximum value for normal symbol hold = 4).

The probability of winning the opening lottery when the high opening/closing mode is set is higher than the probability of winning the opening lottery when the low opening/closing mode is set. The probability of winning the opening lottery when the low opening/closing mode is set may be 0%. Also, the probability of winning the opening lottery when the high opening/closing mode is set may be 100%. In this embodiment, even if the opening lottery is won when the low opening/closing mode is set, the opening time of the second starting area 904b is extremely short, and it is virtually impossible to get the game ball into the second starting area 904b. Therefore, when the low opening/closing mode is set, left-handed play (playing aiming for the first starting area 904a) is recommended. On the other hand, when the high opening/closing mode is set, the opening lottery is easily won, and the opening time of the second starting area 904b in that case is sufficiently long. Therefore, when the high opening/closing mode is set, right-handed play (playing with the aim of targeting the second starting area 904b) is recommended, and if you continuously play right-handed, the game ball will frequently enter the second starting area 904b.

In this embodiment, the normal game state is the low opening/closing mode. The specific game state is the high opening/closing mode. Generally, the high opening/closing mode is referred to as the "time-saving (state)," so the normal game state can be said to be the "no time-saving (state)" state, and the specific game state can be said to be the "time-saving (state)" state. In the following explanation, the low opening/closing mode may also be referred to as the "no time-saving (state)," and the high opening/closing mode may be referred to as the "time-saving (state)." Also, the number of win/loss draws (second win/loss draw in this embodiment) that are the conditions for the high opening/closing mode (time-saving) to end may be referred to as the number of time-saving draws. In this embodiment, a predetermined number of prize balls are dispensed when a game ball enters the starting area 904 (first starting area 904a, second starting area 904b) (the starting area 904 is the prize-winning area). Therefore, the rate at which the number of balls decreases (number of prize balls per number of game balls launched) is lower in the high opening/closing mode than in the low opening/closing mode. In other words, the low-opening/closing mode is a "low-base state" with a relatively low base, while the high-opening/closing mode is a "high-base state" with a relatively high base.

2-5-3) Types of Specific Game States In this embodiment, the following specific game states (high opening/closing modes) are provided: the first specific game state, the second specific game state, and the special specific game state. Each specific game state has a different termination condition for ending the high opening/closing mode. The termination condition is met when either the "variable number condition," which is met when the number of second win/loss draws performed since the start reaches a predetermined value (a predetermined number of time-saving draws), or the "minor win condition," which is met when the number of minor wins achieved since the start reaches a predetermined value (whichever comes first), is met.

Furthermore, since winning a jackpot and executing the jackpot game means that the game state is no longer one in which the goal is to win a jackpot, winning a jackpot can be considered a de facto termination condition for the high-opening/closing mode. Also, while various specific game states are transitioned to after the end of the corresponding jackpot game, the "start" point of each specific game state (high-opening/closing mode) refers to the end point of the corresponding jackpot game. In other words, when transitioning to a certain specific game state after the end of a jackpot game, the above-mentioned variable count conditions and minor win conditions are reset. However, the variable count conditions are only reset when a "jackpot" is won (when the game ball enters the bonus area 10), and are not reset by winning only a "minor win."

The first specific game state is defined as a condition where the second win/loss lottery is performed 70 times after the start of the game. In other words, the number of time-saving rounds is set to 70. As mentioned above, the probability of winning (minor win) in the second win/loss lottery is 1/47. Therefore, the probability of winning the second win/loss lottery before 70 consecutive losses occur after the start of the first specific game state (before the high-opening/closing mode ends) is approximately 78%.

The first specific game state requires two minor wins after the start of the game to be considered a minor win condition. In other words, the high-opening/closing mode does not end after one minor win following the start of the first specific game state. Note that two or more minor wins are sufficient to satisfy the minor win condition for the first specific game state.

The second specific game state is one in which the number of variations is conditional on the second win/loss lottery being executed 1000 times after it starts. In other words, the number of time-saving rounds is set to 1000. As mentioned above, the probability of the second win/loss lottery being a win (minor win) is 1/47, so the probability of losing 1000 times in a row without winning the second win/loss lottery after the second specific game state starts is extremely low. In other words, the second specific game state can be said to be a state in which the continuation of the high opening/closing mode is practically guaranteed until the next minor win (acquisition of a major win via a minor win). Thus, a specific game state with a time-saving round count in which the probability of ending without winning the win/loss lottery is astronomically low (less than 0.1%) is considered a state in which "acquisition of the next major win is practically guaranteed" before the end of the specific game state (high opening/closing mode) (the same applies to the special specific game state described later). Unlike this embodiment, the second specific game state may continue until the next major win is acquired (time-saving rounds = ∞). Even in specific game states that continue until the next jackpot is won, we consider this state (high-opening/closing mode) to be a state where "the next jackpot is effectively guaranteed" before the end of that specific game state.

The second specific game state requires winning a minor win "once" after it has started. In other words, the high-opening/closing mode ends after winning a minor win once after the second specific game state has started.

The Special Specific Game State is a state where the number of variations is conditional on the second win/loss lottery being executed 1000 times after its start. In other words, the number of time-saving rounds is set to 1000. As mentioned above, the probability of winning (minor win) in the second win/loss lottery is 1/47, so it is highly unlikely that the Special Specific Game State would start and result in 1000 consecutive losses without winning the second win/loss lottery. Therefore, the Special Specific Game State effectively guarantees the continuation of the high-opening/closing mode until the next minor win (winning a major win via a minor win).

The special designated game state requires two minor wins after it begins. In other words, the high-opening/closing mode does not end after a single minor win following the start of the special designated game state. Note that two or more minor wins are sufficient to fulfill the minor win condition for the special designated game state.

2-5-4) As described above, if we express the normal game state and the specific game state in terms of the level of the probability of winning the draw (effective jackpot probability) and the presence or absence of a time-saving feature,
(a) Normal game state... "Low probability, no time-saving feature"
(b) Specific game state... "High probability, with time reduction"
That's how it works.

Furthermore, if we represent various specific game states in terms of the probability of winning the draw (effective jackpot probability), the presence or absence of time-saving features (number of time-saving features), and the number of small wins that end the high opening/closing mode,
(b-1) First specific game state: "High probability, time-saving feature (70 spins), 2 small wins"
(b-2) Second specific game state: "High probability, time-saving feature (1000 spins), 1 small win"
(b-3) Special designated game state... "High probability, time reduction (1000 spins), 2 small wins"
That's how it works.

2-6) Types of Jackpots In this embodiment, there are two types of jackpots: normal jackpots and special jackpots. A normal jackpot is a jackpot that transitions to a normal game state after the jackpot game ends (meaning after the end of the last unit game that makes up the jackpot game). A special jackpot is a jackpot that transitions to a special game state after the jackpot game ends. Since the special game state (high probability, with time reduction) is more advantageous to the player than the normal game state (low probability, no time reduction), it can be said that, in terms of the game state after the jackpot game ends (excluding the difference in the number of rounds), a special jackpot is more advantageous to the player than a normal jackpot.

There are three types of special jackpots: the First Special Jackpot, the Second Special Jackpot, and the Extra Special Jackpot. The First Special Jackpot is a jackpot that transitions to the First Special Game State after the jackpot game ends. The Second Special Jackpot is a jackpot that transitions to the Second Special Game State after the jackpot game ends. The Extra Special Jackpot is a jackpot that transitions to the Extra Special Game State after the jackpot game ends. Of the special game states, the Extra Special Game State is the most advantageous (it is the most advantageous of all game states). Therefore, regarding the game state after the jackpot game ends (excluding the number of rounds), the Extra Special Jackpot is the most valuable of the special jackpots.

In this embodiment, the regular jackpot and the first specific jackpot are 2-round (2R) or 10-round (10R) jackpots. The second specific jackpot and the special specific jackpot are all 10-round (10R) jackpots. Except for the points specifically described below, the number of rounds can be changed as appropriate.

2-7) Gameplay Flow 2-7-1) "Number of spins cut type" (first specific game state) and "Loop type" (second specific game state)
The following describes the gameplay flow of the gaming machine 1 according to this embodiment, although some of it overlaps with the explanation above. Note that the flow described below assumes that no abnormalities occur and the player plays the game as instructed (playing left when left-handed is required and right when right-handed is required).

After a predetermined reset operation (which can be performed by the arcade staff, not the player), the initial state is the normal game state (the most unfavorable game state for the player). In this embodiment, the RAM clear operation constitutes the reset operation, while turning the power OFF/ON is not. However, the setting may be configured so that turning the power OFF/ON is the reset operation.

In normal gameplay, the player plays by shooting left-handed. When a game ball enters the first starting area 904a, the first lottery information is acquired. If a minor win is achieved in the first win/fail lottery (special figure 1 lottery) based on the first lottery information (first win/fail lottery information), the minor win game is executed, and a big win is obtained when the game ball enters the bonus area 10 (V-entry) during the minor win game. The type of big win obtained after the first win/fail lottery is determined by referring to the big win distribution table for the first win/fail lottery. In this embodiment, the big win obtained after the first win/fail lottery (big win obtained after the first win/fail lottery) is distributed as follows: 40% are normal big wins (2R), 10% are first specific big wins (2R), and 50% are special specific big wins (10R) (see Figure 6(a)). Normally, if a jackpot is won, the game returns to normal gameplay after the jackpot round ends (see Figure 4), and the player continues playing in normal gameplay mode, aiming to win another jackpot.

If a first specific jackpot is achieved, the game transitions to the first specific game state (see Figure 4). In the first specific game state, the player plays by shooting to the right. Second lottery information is acquired when the game ball enters the second starting area 904b. If a minor win is achieved in the second win/fail lottery (special figure 2 lottery) based on the second lottery information (second win/fail lottery information), the minor win game is executed, and a jackpot is won when the game ball enters the bonus area 10 (V-entry) during the minor win game. The first specific game state is a "high probability, time-saving (70 spins)" state. Therefore, the goal of the game is to win the jackpot by getting a win (minor win) in the second win/fail lottery result before the second win/fail lottery result is a loss for 70 consecutive spins. In other words, if the second draw result is a loss for 70 consecutive times, the game transitions to a normal game state (however, it first transitions to a remaining-reserve chance state (details below)). Therefore, this game state aims to win a jackpot before the second draw result is a loss for 70 consecutive times, in order to avoid transitioning to the normal game state. This type of gameplay, where a state where it is easy to win a jackpot continues until a predetermined number of losses (70 in this embodiment) occur, is generally referred to as "count limit" or "ST" (hereinafter referred to as "count limit type").

The type of jackpot won after the second win/loss lottery (special figure 2 lottery) is determined based on the jackpot distribution table for the second win/loss lottery. Here, for the second win/loss lottery, the table referenced differs depending on whether the machine is in high-opening/closing mode ("time-saving mode enabled") or not ("time-saving mode disabled") when the jackpot is won. In other words, the "jackpot distribution" differs depending on whether the machine is in "time-saving mode enabled" or "time-saving mode disabled" when the jackpot is won. Furthermore, in this embodiment, the "jackpot win" (the point at which the jackpot is determined) is when the game ball enters the bonus area 10 during a minor win game, i.e., when a V-win occurs. Therefore, the "jackpot distribution" differs depending on whether the machine is in "time-saving mode enabled" or "time-saving mode disabled" at the time of the V-win (see Figure 6(b)).

The first specific game state has two minor win conditions (see Figure 5). Therefore, the high-opening/closing mode (time-saving mode) does not end (the minor win condition is not met) after the first minor win (one minor win) following the start of the first specific game state. Thus, at the point when a V-entry occurs in the minor win game executed after the first minor win (when the big win is determined), the state is "time-saving mode enabled." If no abnormalities occur and the player continuously fires game balls aiming for the bonus area 10 as instructed, a V-entry will almost certainly occur in that first minor win game (no malfunction will occur). Therefore, the type of big win obtained in the first specific game state is determined by referring to the "time-saving mode enabled" table. Thus, the distribution of big wins obtained in the first specific game state is basically (if no malfunction occurs) 95% for the first specific big win (10R) and 5% for the special specific big win (10R) (see Figure 6 (b-1)).

If the second win/loss lottery result is a loss for 70 consecutive time-saving rounds after the start of the first specific game state (resulting in a "time-saving round exit"), the condition for the number of variations is met, and the first specific game state ends, transitioning to the normal game state. However, immediately after the end of the first specific game state, the second reserve information (special symbol 2 reserve) remains in the memory (hereinafter, the second reserve information remaining at the end of the first specific game state may be referred to as the remaining reserve), so the second win/loss lottery with a "high probability" (1/47) is executed for the remaining reserve (hereinafter, this high probability lottery for the remaining reserve will be referred to as the "remaining reserve chance") (see Figure 4).

In this embodiment, during the 70th losing spin (the final spin of the time-saving mode) after the start of the first specific game state, an animation prompting the player to accumulate four second-reserve information (hereinafter, the state in which four second-reserve information is stored may be referred to as "reserve full") is executed (reserve storage instruction animation) (see Figure 7(a)). When the reserve is full, an animation indicating this (reserve storage completion animation) (see Figure 7(b)) is executed. Note that if the reserve is already full at a predetermined point in the final spin of the time-saving mode, the reserve storage instruction animation may be omitted.

During the final spin of the time-saving mode, the above-mentioned hold-storage instruction animation is executed. Therefore, normally, when the first specific game state ends, four second-stage hold-storage information slots remain. This means you have the right to receive four chances at the second win/loss lottery (high-probability lottery) with a winning probability of 1/47. This is the "remaining hold-storage chance." In other words, while the state in which the "remaining hold-storage chance" is executed is technically already the normal game state, the animation corresponding to the "remaining hold-storage chance" is executed to make it appear as if you are still in an advantageous state (not the normal game state) until the high-probability lottery is completed, because four chances remain.

The in-game animations (four in-game animations) performed during the remaining reserve chance are special and will not be performed when the remaining reserve chance is not active. In this embodiment, an animation for the remaining reserve chance called "○○ Chance" (see Figure 8(a)) is performed. During the remaining reserve chance, the results of the win/fail lottery corresponding to the second reserve information (second win/fail lottery information), which was acquired earlier, are announced first. In this embodiment, if the win/fail lottery result is a win (minor win), an animation is performed that leads to a success result (see Figure 8(b) → (c-1)) indicating that the situation is favorable to the player, and if it is a loss, an animation is performed that leads to a failure result (see Figure 8(b) → (c-2)) indicating that the situation is unfavorable to the player (Note that the success result includes a so-called reversal pattern where it appears to be a failure but is then reversed). If the result is a success, a minor win game is performed. If the result is a failure, the next in-game animation is started. If all four of these second-round draws (high-probability draws) result in losses, the remaining chance ends and the player is prompted to play with left-hand shots. In other words, the goal becomes to win a jackpot after the first-round draw.

As will be explained in more detail later, if you win the second win/loss lottery during the remaining reserve chance, the jackpot you will receive will be either a regular jackpot or a second specific jackpot. In this embodiment, the type of jackpot won is announced during the battle sequence during the jackpot game (see Figure 9), and the name of the jackpot (prize) encompassing both the regular jackpot and the second specific jackpot is called "Battle Bonus." Therefore, during the remaining reserve chance, a sequence using an image representing the Battle Bonus prize (hereinafter referred to as the prize image) is executed. Specifically, in each sequence, the prize image is displayed at a stage where it is not yet known whether the result will be a success or a failure (see Figure 8(b)). In this way, the player can know in advance that if the sequence is successful, they will receive the prize represented by the prize image (making the sequence easier to understand). If a successful outcome is achieved, an image indicating a favorable situation (in this embodiment, the word "Success") is displayed along with the reward image that was displayed in the previous stage (stage 8(b)) (see Figure 8(c-1)), making it easy to understand that the reward has been obtained. On the other hand, if a failure occurs, an image indicating an unfortunate situation (in this embodiment, the word "Failure") is displayed, and the reward image that was displayed in the previous stage (stage 8(b)) is no longer displayed (see Figure 8(c-2)), making it easy to understand that the reward was not obtained.

If a minor win is achieved in the second draw of the remaining reserve chance, the minor win game is executed (see Figure 9(a)). A jackpot is won by hitting the V-slot during this minor win game. Here, since the state in which the remaining reserve chance is executed is already the state of no time-saving mode after the high opening/closing mode has ended, the state at which the jackpot is won (when the V-slot is hit) is also the state of no time-saving mode. Therefore, the type of jackpot won after the second draw of the remaining reserve chance is determined by referring to the "no time-saving mode" table. That is, the distribution of jackpots won in the remaining reserve chance is 79% for the second specific jackpot (10R) and 21% for the regular jackpot (10R) (see Figure 6(b-2)). If a second specific jackpot is won, the game transitions to the second specific game state after the jackpot game ends (see Figure 4). If a regular jackpot is won, the game transitions to the regular game state after the jackpot game ends (see Figure 4).

In this embodiment, whether a second specific jackpot or a regular jackpot has been won is announced during the jackpot game after a V-win. In this embodiment, the outcome is announced via a battle sequence (see Figure 9(b)). This battle sequence leads to either a victory ending (a favorable outcome for the player) where the player's character wins (see Figure 9(c-1)) or a defeat ending (a disadvantageous outcome for the player) where the character loses (see Figure 9(c-2)). (Note that the victory ending includes a so-called reversal pattern where a defeat is initially apparent but then reversed.) If the won jackpot is a second specific jackpot, a victory ending occurs; if it is a regular jackpot, a defeat ending occurs. If a victory ending occurs, the second specific game state begins after the jackpot game ends. On the other hand, if a defeat ending occurs, the game transitions to the regular game state after the jackpot game ends.

Furthermore, if you win a minor prize in the first to third of the four second-win/loss draws performed as part of the remaining reserve chance, and thus obtain a regular jackpot, then after that regular jackpot, the remaining second-win/loss draws (one of the first to third) will be performed (see (i) below in Figure 9 (c-2)). For example, suppose you win a regular jackpot in the third second-win/loss draw from the start of the remaining reserve chance. In that case, after the regular jackpot game ends, the second-win/loss draw for the remaining one second-win/loss information will be performed. If you win the second-win/loss draw again there and obtain a second-specific jackpot, then after the jackpot game ends, you will transition to the second-specific game state. In other words, the remaining reserve chance ends either when you "obtain a second-specific jackpot" or when the fourth second-win/loss draw from the start of the remaining reserve chance ends. Therefore, even if you obtain a regular jackpot in the first to third second-win/loss draws, if you obtain a second-specific jackpot in the remaining second-win/loss draws, you may transition to the second-specific game state after the remaining reserve chance.

If the fourth second draw after the start of the remaining chance is unsuccessful, or if the resulting jackpot is a regular jackpot even if a win was achieved, the game will transition to a state where left-handed play is encouraged. In other words, the goal is to win a jackpot after the first draw.

If a second specific jackpot is won during the remaining reserve chance, the game transitions to the second specific game state (see Figure 4). The second specific game state has 1000 time-saving spins, and it is virtually guaranteed that the next jackpot will be won before the high-opening/closing mode ends. Therefore, in the second specific game state, losing spins are rapidly processed until a minor win is achieved. Then, after winning a minor win in the second win/loss lottery, a jackpot is won.

Here, in the second specific game state (unlike the first specific game state described above), the condition for a minor win is set to one (see Figure 5). Therefore, the high opening/closing mode (time reduction) ends with the first minor win after the start of the second specific game state. Thus, at the point when a V-entry is achieved in the minor win game executed after the first minor win (when the big win is determined), the state is "no time reduction". If no abnormalities occur and the player continuously fires game balls aiming for the bonus area 10 as instructed, a V-entry will almost certainly occur in the first minor win game (no malfunction will occur). Therefore, the type of big win obtained in the second specific game state is determined by referring to the "no time reduction" table. Thus, the distribution of big wins obtained in the first specific game state is basically (if no malfunction occurs) 79% for the second specific big win (10R) and 21% for the regular big win (10R) (see Figure 6 (b-2)). Note that this distribution is the same as the distribution for big wins obtained during the remaining reserve chance.

Thus, the second specific game state is effectively a state where the next jackpot is guaranteed, and that jackpot has a 79% probability of becoming a second specific jackpot, leading back to the second specific game state. In other words, once you enter the second specific game state, the advantageous game state (high probability and high opening/closing mode) that is guaranteed to continue until the next jackpot loops at a predetermined probability, creating a "loop type" gameplay.

If a regular jackpot is won in the second specific game state, the game returns to the regular game state after the jackpot game ends. In this embodiment, even after the regular jackpot game won in the second specific game state ends, the game returns to the "remaining reserve chance" state. In order to return to this remaining reserve chance state, the game must have four second reserve information entries stored (a state of full reserves) at the end of the second specific game state. Therefore, in this embodiment, the following control is performed in the second specific game state.

As described above, the second specific game state is a state in which the next big win is practically guaranteed, so losing spins where the second win/loss lottery result is a loss are processed at high speed. Then, in winning spins where the win/loss lottery result is a win (minor win), an animation for accumulating reserves (reserve storage instruction animation) is executed (the reserve storage instruction animation is not executed in losing spins) (see Figure 10(a)). In other words, winning spins have a somewhat longer spin time than losing spins, ensuring sufficient time to fill the second reserve information. After the reserve storage instruction animation, an animation indicating that the reserves are full (reserve storage completion animation) is executed when the reserves reach a full state (see Figure 10(b)). Note that these reserve storage instruction animations and reserve storage completion animations may be the same as or different from those executed in the final spin of the time-saving state of the first specific game state described above. After that, it is announced that the win/loss lottery result is a win (minor win) (see Figure 10(c)). At this point, the player is not explicitly informed whether the jackpot won is a second-special jackpot or a regular jackpot. In other words, the aforementioned reserve storage instruction animation will be executed during the win animation regardless of whether the jackpot won in the future will be a second-special jackpot or a regular jackpot. Furthermore, during the jackpot game after a V-entry, the player will be informed whether the won jackpot is a second-special jackpot or a regular jackpot through the battle animation; therefore, in this embodiment, the name "Battle Bonus" is displayed (see Figure 10(c)). That is, the name "Battle Bonus" indicates that the jackpot won after a V-entry is either a regular jackpot or a second-special jackpot.

The subsequent progression is the same as when a minor win is achieved during the remaining chance. Specifically, during the minor win game, instructions are given to aim for the bonus area 10 when launching the game ball (see Figure 9(a)). Upon hitting the V-slot, a jackpot is won, and the jackpot game begins. During the jackpot game, a battle sequence (see Figures 9(b), (c-1), and (c-2)) is performed to indicate whether the won jackpot is a second-special jackpot or a regular jackpot.

As mentioned above, during the winning spin in the second specific game state, the reserve storage instruction animation is executed, so the reserve should already be full when that winning spin ends. Therefore, even if the acquired jackpot is a regular jackpot (the battle animation during the jackpot game ends in defeat) and the game returns to the regular game state, the player still has the right to receive four more chances in the second win/loss lottery (a remaining reserve chance occurs) (see (b) below in Figure 9 (c-2)).

Furthermore, it may be possible to include cases where, during a winning spin, it is confirmed that the winning jackpot will be a second-specific jackpot. In such cases, since the game returns to the second-specific game state after the second-specific jackpot game ends (without returning to the remaining reserve chance), the reserve storage instruction animation may be omitted during the winning spin.

The remaining reserved chance is the same as the one performed after the first specific game state (after the time-saving mode ends) as described above, so the explanation is omitted. The presentation (the manner of the presentation announcing the win/loss result, the name of the presentation, etc.) of the remaining reserved chance performed after the first specific game state and the remaining reserved chance performed after the second specific game state may be different.

As described above, the gaming machine 1 according to this embodiment has a "count-limit type" (ST type) gameplay in the first specific game state, aiming to win a jackpot before a predetermined number of consecutive losses (70 times in this embodiment). In the second specific game state, it has a "loop type" gameplay, aiming for the next jackpot, which is virtually guaranteed to be won, to be a second specific jackpot (not a regular jackpot). In other words, it is a novel design that allows players to experience both the "count-limit type" (ST type) gameplay and the "loop type" gameplay in the same gaming machine (one model).

Furthermore, in this embodiment, there is no possibility of transitioning from the normal game state (excluding the remaining reserve chance) to the second specific game state (it is not possible to obtain the second specific jackpot in the normal game state (excluding the remaining reserve chance)). The condition for transitioning to the second specific game state is obtaining the second specific jackpot during the remaining reserve chance after the first specific game state has ended. Therefore, a player starting from the normal game state (excluding the remaining reserve chance) will first aim to transition to the first specific game state, and if that first specific game state ends, will aim to acquire the right to transition to the second specific game state during the remaining reserve chance.

In particular, in this embodiment, the probability of winning a minor win and obtaining the first specific jackpot before the first specific game state ends due to the number of fluctuations condition (exiting the time-saving mode) is approximately 78%, while the probability of obtaining the second specific jackpot in the second specific game state is approximately 79%. In other words, the so-called continuation rate is higher in the second specific game state than in the first specific game state. Therefore, it can be said that the second specific game state, which is relatively difficult to transition to, is a more valuable state than the first specific game state, which is relatively easy to transition to. Alternatively, it can be said that the interesting gameplay lies in the fact that obtaining a jackpot during the remaining reserve chance after the end of the first specific game state is a condition for transitioning to the more advantageous second specific game state.

2-7-2) Special Specific Jackpot (Special Specific Game State)
Special jackpots are jackpots that can be won by winning the first win/loss lottery in normal gameplay (excluding remaining reserve chances) and by winning the second win/loss lottery in the first specific gameplay state, and all of them are 10 rounds (see Figures 4 and 6). Therefore, in a single special jackpot game, if you continuously play to the right to a certain extent so that the winning conditions are met before the time conditions are met in each unit of gameplay, you will receive a minimum of 15 x 10 x 10 (prize balls x count x number of rounds) = 1500 prize balls.

The special special game state, which is entered after the end of a special special jackpot game, has 1000 time-saving spins, and is a state where it is virtually guaranteed that the next jackpot will be won before the high-opening/closing mode ends. In other words, it is the same as the second special game state in that the next jackpot is virtually guaranteed. Because the next jackpot is virtually guaranteed in this way, in the special special game state, losing spins end very quickly until a minor win is achieved. Then, as with other game states, a jackpot is won by winning a minor win.

Here, in the special specific game state (unlike the second specific game state described above), the conditions for a minor win are set to occur twice (see Figure 5). Therefore, the high opening/closing mode (time reduction) does not end (the minor win condition is not met) when the first minor win occurs after the start of the first specific game state (one minor win). Thus, at the point when a V-entry is achieved in the minor win game executed after the first minor win (the point when a big win is determined), the state is "time reduction enabled". If no abnormalities occur and the player continuously fires game balls aiming for the bonus area 10 as instructed, a V-entry will almost certainly occur in the first minor win game (no malfunction will occur). Therefore, the type of big win obtained in the special specific game state is determined by referring to the "time reduction enabled" table. Therefore, the distribution of jackpots obtained during the special designated game state is basically (unless a "bust" occurs) 95% for the first designated jackpot (10R) and 5% for the special designated jackpot (10R) (see Figure 6 (b-1)).

In short, the Second Specific Game State and the Special Specific Game State share the commonality of being states where the next jackpot is virtually guaranteed before the high-opening/closing mode ends. However, the conditions for a minor win in the Second Specific Game State are one minor win, while the conditions for a minor win in the Special Specific Game State are two minor wins. Therefore, the reference table (jackpot distribution) when a jackpot is won differs: the former has "no time reduction" (see Figure 6 (b-2)), and the latter has "time reduction" (see Figure 6 (b-1)). One of the major differences is that the former has the possibility of a normal jackpot, while the latter does not. From the player's perspective, the Second Specific Game State carries the risk of transitioning to the normal game state after the jackpot game ends, but the Special Specific Game State does not transition to the normal game state after the jackpot game ends (it transitions to either the First Specific Game State or the Special Specific Game State).

Furthermore, both the First Specific Jackpot and the Special Specific Jackpot, which can be obtained in the Special Specific Game State, are 10 rounds long. This means that even with a jackpot obtained in the Special Specific Game State, the minimum prize payout is 15 x 10 x 10 (prize payout x count x rounds) = 1500 balls.

To summarize, the following can be said: When a special jackpot is won, a minimum of 3000 balls are effectively guaranteed: the minimum 1500 balls awarded for that special jackpot (sometimes referred to as the "first jackpot") plus the minimum 1500 balls awarded for the subsequent jackpot in the special game state (sometimes referred to as the "second jackpot"). Furthermore, the special game state (high probability and high opening/closing mode) continues even after the second jackpot ends. Therefore, winning a special jackpot guarantees both "3000 balls" and the "special game state (after the second jackpot ends)."

In this embodiment, the name (title) of the special jackpot includes "3000," which indicates the minimum number of prize balls that can be obtained (see Figure 11). When a special jackpot is won, this name is displayed at the beginning of the winning spin or the special jackpot game that triggered the win. In this embodiment, the special jackpot is named "Special Bonus 3000."

As described above, the gaming machine 1 according to this embodiment is equipped with a special designated jackpot as a premium jackpot that guarantees a prize of 3,000 balls. Since this special designated jackpot can be obtained even during normal gameplay (excluding remaining reserve chances) (i.e., as a so-called initial win), it contributes to promoting gameplay. In particular, in this embodiment, 50% of the jackpots obtained after the first win/loss lottery are special designated jackpots, and the probability of obtaining this jackpot immediately is quite high, thus having a significant effect in promoting gameplay. In addition, since there is a possibility of obtaining a special designated jackpot even in the first designated gameplay state, which is a so-called "count-limited" type of gameplay, it is also possible to expect a larger payout during consecutive wins.

Furthermore, after winning a special specific jackpot (the previous jackpot), the game will not revert to the normal game state after the subsequent jackpot game, which is won in the special specific game state. In other words, the special specific game state is considered a "guaranteed consecutive win" game state. If the game were to revert to the normal game state after the premium jackpot (the subsequent jackpot) which awards 3000 balls, players would lose interest. Therefore, after the subsequent jackpot game ends, the game transitions to a specific game state (high probability and high opening/closing mode).

Furthermore, the reason why it is possible to have both the second specific game state as a "loop type" game state and the special specific game state as a "guaranteed winning streak" game state is that the conditions for small wins (termination conditions) are different for the second specific game state and the special specific game state, which are similar in that the next big win is virtually guaranteed during the high opening/closing mode (a so-called long time-saving mode). In order to make it a "loop type," there must be a possibility of winning a regular big win (a possibility of falling back to the regular game state). On the other hand, in order to make it a "guaranteed winning streak," the possibility of winning a regular big win (a possibility of falling back to the regular game state) must be eliminated. In other words, the big win distribution must be different for the second specific game state and the special specific game state. Therefore, while both the second specific game state and the special specific game state are set to long time-saving mode (1000 time-saving rounds in this embodiment), effectively guaranteeing the next big win, the conditions for small wins are different. In the former, the time-saving mode is disabled upon V-entry (the "No Time-Saving Mode" table is referenced), so that a regular big win is included in the big win distribution (see Figure 6(b-2)). In the latter, the time-saving mode is enabled upon V-entry (the "Time-Saving Mode" table is referenced), so that a regular big win is not included in the big win distribution (see Figure 6(b-1)).

2-8) Control when a "puncture" occurs: The first specific game state, which is a high opening/closing mode, is one in which the conditions for a minor win are set to be two. Therefore, when a minor win occurs for the first time after the first specific game state has started, the high opening/closing mode (time reduction) does not end, and normally (if no abnormalities occur and the game is played as instructed), a V-win will occur in that first minor win game, so the type of big win will be determined by the distribution with "time reduction" (see Figure 6 (b-1)).

However, if, during the first minor win game after the start of the first specific game state, the ball does not enter the V-zone due to an abnormality or the player not playing as instructed (not continuously shooting to the right), it will result in a "puncture" and the jackpot will not be awarded. (Hereafter, the event in which the game ball does not enter the bonus area 10 (does not enter the V-zone) during a minor win game may be referred to as a "non-entry event." The occurrence of a "non-entry event" is equivalent to the occurrence of a "puncture").

However, the termination condition for the first specific game state is met when either the fluctuation count condition (number of time-saving rounds) = 70 rounds or the minor win condition 2 rounds is met. Therefore, even if such a "bust" occurs, if there are still time-saving rounds remaining, the fluctuations of the first specific game state will start again after the minor win game ends (fluctuations for the remaining time-saving rounds will start). For example, if a minor win is achieved in the 50th second win/loss draw after the first specific game state has started, but the minor win game "busts", then after the end of the minor win game, fluctuations will start to announce the result of the 51st second win/loss draw (the 51st spin of the time-saving round). In this embodiment, a distinction is made between the state before a bust (non-entry event) occurs in the first specific game state (hereinafter sometimes referred to as the normal state) and the state after a bust (non-entry event) occurs (hereinafter sometimes referred to as the special state). In the example above, the normal state lasts from the start of the first specific game state until the 50th spin, and the special state lasts from the 51st spin until the end of the first specific game state (see Figure 12).

When a "puncture" occurs in the first specific game state, information indicating that a special state is in place (hereinafter referred to as "special information") is stored in the memory means (see Figure 12). In other words, if special information is stored in the memory means, the game is currently in a special state; if special information is not stored, the game is currently in a normal state. It is preferable that the memory means that stores the special information is a non-volatile memory means that does not lose its memory even when the power is turned off. In other words, it is preferable that the information indicating that a special state is in place remains even if a power outage occurs. In this embodiment, the special information is stored in the memory means of the main control board (main control circuit). The gaming machine 1 according to this embodiment, like a typical gaming machine, has a main control board (main control circuit) that performs the win/loss lottery and a sub-control board (sub-control circuit) that determines the content of the performance to be executed based on the win/loss lottery results (the main control board and sub-control board themselves are well known, so a detailed explanation will be omitted). However, special information is stored in the storage means of the main control board (main control circuit), which retains its memory even when the power is turned off, rather than in the storage means of the sub-control board (sub-control circuit), which loses its memory when the power is turned off.

The type of animation that constitutes the in-game animation and is executed when a predetermined condition is met differs depending on whether the game is in a normal state or a special state. In this embodiment, the target animations are "display of winning combinations" and "display of bonus name (jackpot name)."

Regarding the "display of winning combinations," in the normal state, when the result of the win/loss lottery is a win, i.e., in a win variation, three matching "7" decorative symbols 80 are displayed to announce the win (see Figure 13(a)). Since a minor win in the normal state is the first minor win after the start of the first specific game state, the high opening/closing mode (time reduction) does not end. Therefore, when a V is hit, the type of jackpot is determined by the "time reduction available" jackpot distribution (see Figure 6(b-1)). In this "time reduction available" jackpot distribution, there is usually no jackpot (after the jackpot game ends, it transitions to a specific game state (first specific game state or special specific game state), and does not transition to the normal game state), so the win is announced by three matching "7" decorative symbols 80. In the technical field of this invention, the "7" symbol is usually set as a valuable symbol, and many players think so. Since the "Time-Saving Bonus" jackpot distribution does not normally result in a jackpot, the win is indicated by the decorative "7" symbol (number 80), which is the valuable symbol in question.

In contrast, in the special state, when the draw result is a win, i.e., a win variation, the display of three "7" decorative symbols 80 is prevented. In this embodiment, three of any of the decorative symbols 80 other than "7" are displayed (see Figure 13(b)). It is also possible to have a configuration in which it is predetermined which of the decorative symbols 80 other than "7" will be displayed (for example, a configuration in which it is predetermined that three of the "6" decorative symbols 80 will be displayed). Since a minor win in the special state is the second minor win since the start of the first specific game state, the high opening/closing mode (time reduction) ends. Therefore, when a V is hit, the type of jackpot is determined by the "no time reduction" jackpot distribution (see Figure 6(b-2)). This "no time reduction" jackpot distribution has the potential to result in a regular jackpot. Therefore, as mentioned above, if a win is announced by a triple match of the "7" decorative symbol 80, which is generally recognized as a valuable symbol, there is a possibility that the game may revert to normal gameplay even after the "7" decorative symbol 80 has appeared (which could lead to complaints from players). Therefore, in this embodiment, in the special state, the game is controlled to display a different symbol combination (a triple match of decorative symbols 80 other than the "7" decorative symbol 80) than the "triple match of the "7" decorative symbol 80" displayed in the normal state described above.

Regarding the display of bonus names (jackpot names), the names of jackpots obtainable after a V-win in the normal state and the names of jackpots obtainable after a V-win in the special state are different. Jackpots obtainable in the normal state (jackpots obtainable with the "Time-Saving Bonus" jackpot distribution (see Figure 6 (b-1))) are either the First Specific Jackpot or the Special Specific Jackpot. As mentioned above, in this embodiment, the Special Specific Jackpot is named "Special Bonus 3000" (see Figure 13 (a-2)). On the other hand, the First Specific Jackpot is named "Big Bonus" (see Figure 13 (a-1)). Therefore, when indicating jackpots to be obtained in the future (after a V-win) during win fluctuations in the normal state, the names "Special Bonus 3000" or "Big Bonus" are used.

On the other hand, the jackpots that can be obtained in a special state (jackpots that can be obtained in the "no time-saving" jackpot distribution (see Figure 6(b-2))) are either the second specific jackpot or the regular jackpot. As mentioned above, which jackpot has been obtained is announced during the jackpot game's presentation (battle presentation) (see Figure 9), and before this is determined, the name "Battle Bonus" is used (the name "Battle Bonus" can be said to be a name that comprehensively refers to both the second specific jackpot and the regular jackpot) (see Figure 13(b)). Therefore, when referring to the jackpot that will be obtained in the future (after a V-win) during the jackpot variation in a special state, the name "Battle Bonus" is used.

Furthermore, in special states, the aforementioned reserve storage instruction animation may be executed during winning spins. Since a jackpot won in a special state may become a regular jackpot, in that case, to ensure that the second reserve information is full when transitioning to the remaining reserve chance, the reserve storage instruction animation will occur, instructing the player to accumulate reserves.

Thus, in this embodiment, the first specific game state, under normal circumstances (if no malfunction occurs), determines the type of jackpot with a "time-saving" jackpot distribution (see Figure 6(b-1)). However, after one malfunction occurs, if a minor win is achieved again, the type of jackpot obtained from that minor win will be determined by a "time-saving" jackpot distribution (see Figure 6(b-2)). Since the jackpot distribution differs (the type of jackpot awarded differs) between the normal state (where no malfunction has occurred) and the special state (where a malfunction has already occurred), the mode of the target performance is determined after determining whether the state is normal or special. In this embodiment, "display of winning combinations" and "display of bonus names" are the target performances, but a configuration where only one of them is the target performance is also possible. Furthermore, "display of winning combinations" and "display of bonus names" may occur at different times. Also, a configuration where other performances are the target performances is also possible.

Whether the system is in a normal or special state is determined by whether or not special information exists in the non-volatile memory. Therefore, if a power outage occurs while the system is in a special state and is subsequently restored, gameplay will resume in the special state. In other words, a power outage or other anomaly will not cause the jackpot distribution to change before and after the anomaly occurred (power outages and other anomalies will not affect the player's profits).

In this embodiment, the minor win condition for the first specific game state is set to two minor wins (see Figure 5), but the minor win condition may be set to three or more. Since the first specific game state is basically designed to apply the jackpot distribution of the "Time-Saving" state (see Figure 6(b-1)), it is sufficient that the high-opening/closing mode does not end after the first minor win from the start of the first specific game state. Even if the minor win condition for the first specific game state is set to three or more, the high-opening/closing mode will not end after one minor win, so the jackpot distribution of the "Time-Saving" state will be applied. In other words, the first specific game state only needs to end after N minor wins (N is 2 or more).

Furthermore, the special state is the state in which the high-opening/closing mode ends upon the next minor win (if a V-win occurs in the next minor win game, the "no time reduction" jackpot distribution (see Figure 6 (b-2)) is applied). Based on this, the normal state is from the start of the first specific game state until N-1 minor wins (until N-1 failures occur), and the special state is after N-1 minor wins (after N-1 failures occur). For example, if the minor win condition is 3 minor wins (N=3), then the normal state is from the start of the first specific game state until 2 minor wins (until 2 failures occur), and the special state is after 2 minor wins (after 2 failures occur).

Furthermore, similar control (control that determines the target animation based on whether the game is in a normal or special state) is also executed in the special specific game state where the minor win condition is set to two times, just as in the first specific game state.

The following describes specific examples of improvements, modifications, and implementations of the above-mentioned aspects of gameplay. Furthermore, whenever possible, a configuration may be created that applies multiple aspects described using the following specific examples.

○Specific Example 1-1
In the above embodiment, a special specific jackpot is provided as the jackpot, and a special specific game state is provided as the game state to which the player transitions after the special specific jackpot game ends. However, even without these features, it is possible to realize a gameplay that combines both the "number of spins type" (ST type) and the "loop type".

For example, a game flow like the one shown in Figure 14 is conceivable (assuming the termination conditions for the first and second specific game states (variation count conditions and minor win conditions) are the same as in the above embodiment (see Figure 5)). In the normal game state (excluding the remaining reserve chance), a normal jackpot or the first specific jackpot can be obtained after the first win/loss lottery (it may also be 100% the first specific jackpot). After the first specific jackpot game ends, the game transitions to the first specific game state, and a "count-limited type" (ST type) game is executed. If the "time-saving mode ends," the remaining reserve chance is executed, and if a second specific jackpot is obtained there, the game transitions to the second specific game state, and a "loop type" game is executed.

○Specific Examples 1 and 2
In the above embodiment, it was explained that the first specific game state is two (two or more) small win conditions and the second specific game state is one small win condition. However, by reversing these settings, it is possible to realize gameplay in which the "number of spins type" (ST type) and the "loop type" alternate. Such gameplay can be realized, for example, by using the configuration shown in Figures 15 and 16.

The first specific game state is defined as one minor win condition, and the second specific game state is defined as two (or more) minor win conditions (see Figure 16(a)). In this case, if a minor win is achieved in the first specific game state, the high-opening/closing mode has already ended by the time the V-entry is achieved, so the "no time reduction" jackpot distribution (see Figure 16(b-2)) is applied. By designating the jackpot obtained through this distribution as the second specific jackpot (preventing the first specific jackpot from being obtained), the game transitions to the second specific game state after the end of the second specific jackpot game (see Figure 15).

The second specific game state requires two (or more) minor wins. Therefore, when the first minor win occurs after the second specific game state begins, the high-opening/closing mode has not yet ended. Thus, if a V-win occurs during this first minor win, the "time-saving" jackpot distribution (see Figure 16 (b-1)) is applied. By ensuring that the first specific jackpot is included in the jackpots obtained through this distribution (and that the second specific jackpot is not obtained), the game transitions to the first specific game state after the first specific jackpot game ends (see Figure 15).

In this way, by making it possible to win the second specific jackpot (but not the first specific jackpot) during the first specific game state, and the first specific jackpot (but not the second specific jackpot) during the second specific game state, a gameplay style can be achieved where, during so-called consecutive wins (when the specific game state continues), the first specific game state, which is a "count-limited type" (ST type), and the second specific game state, which is a "loop type," alternate.

○Specific Examples 1 and 3
In the above embodiment, we explained that the gameplay is such that the first objective is to transition to a first specific game state, which is a "count-limited type" (ST type), and the condition for transitioning to a second specific game state, which is a "loop type," is to win a jackpot in the remaining reserved chance after the first specific game state ends. However, the opposite configuration is also possible, that is, the condition for transitioning to a first specific game state, which is a "count-limited type" (ST type), is to win a jackpot in the remaining reserved chance after the second specific game state, which is a "loop type," ends. For example, this type of gameplay can be realized by using the configurations shown in Figures 17 and 18.

In normal gameplay (excluding remaining bonus rounds), the jackpots that can be won do not include the first specific jackpot, but they do include the second specific jackpot (see Figure 17). Therefore, players should first aim to win the second specific jackpot.

The second specific game state is defined as two (or more) minor win conditions (see Figure 18(a)). Therefore, when the first minor win is achieved after the second specific game state begins, the high-opening/closing mode has not yet ended. Thus, if a V-win is achieved during this first minor win, the "time-saving" jackpot distribution (see Figure 18(b-1)) is applied. The jackpot obtained through this distribution is either a second specific jackpot or a regular jackpot. If a second specific jackpot is obtained, the game returns to the second specific game state after the jackpot game ends. In other words, obtaining a second specific jackpot constitutes a winning streak.

If a regular jackpot is won in the second specific game state, the game returns to the normal game state. However, a "Remaining Reserve Chance" is triggered, allowing the player to receive a second chance at winning or losing based on the four remaining reserved balls (second reserved information) stored during the winning spin in the second specific game state (high probability). Furthermore, the reserved ball storage instruction animation described in the above embodiment is executed during the winning spin in the second specific game state.

Since the remaining reserve chance is already in the normal game state, the type of jackpot won in that remaining reserve chance is determined based on the jackpot distribution for "no time reduction" (see Figure 18 (b-2)). The "no time reduction" jackpot distribution is 100% the first specific jackpot, and after the completion of that first specific jackpot game, the game returns to the first specific game state. If all four second win/loss draws are unsuccessful, the remaining reserve chance ends and the game returns to a state where left-hand play is encouraged. In other words, the goal is to win a jackpot after the first win/loss draw.

The first specific game state is defined as one minor win condition (see Figure 18(a)). Therefore, when the first minor win occurs after the start of the first specific game state, the high-opening/closing mode ends. Consequently, if a V-win occurs during this first minor win, the "no time-saving" jackpot distribution (see Figure 18(b-2)) is applied. Since the "no time-saving" jackpot distribution is 100% the first specific jackpot, the game returns to the first specific game state after the end of this first specific jackpot game.

If the game fails to hit the target for the first specified game state for a consecutive number of time-saving rounds (e.g., 70 rounds), the first specified game state, which is favorable for fulfilling the spin count condition, ends, and the game returns to the remaining reserve chance state. During the final spin of the time-saving round, the reserve storage instruction animation described in the above embodiment is executed.

Thus, while the game does not transition from the normal game state (excluding the remaining reserve chance) to the first specific game state, it is possible to transition from the normal game state (excluding the remaining reserve chance) to the second specific game state. Furthermore, by allowing a transition to the first specific game state upon winning a jackpot during the remaining reserve chance after the second specific game state ends, the gameplay is designed so that the player first aims to transition to the "loop type" second specific game state, and then, upon winning a jackpot during the remaining reserve chance after the second specific game state ends, the player is required to transition to the "count-limited type" (ST type) first specific game state.

○Specific Examples 1 and 4
The system is designed to allow players to determine if a special state is entered during the first specific game state and if a jackpot is won during that special state. The special state is entered when a "puncture" occurs, and therefore it is a state that would not normally occur. A jackpot won during this special state may be a regular jackpot, which could lead to complaints from players. Therefore, if a jackpot is won after winning a small prize during the special state, this fact is made clear from an image displayed in the display area 911 (see Figure 19; hereinafter referred to as the discrimination image 20).

The discrimination image 20 is preferably displayed small near the outer edge of the display area 911 so as not to interfere with the player's attention (i.e., not to interfere with the game's presentation). Alternatively, the discrimination image 20 may be located outside the display area 911 (e.g., by the illumination of a lamp). For example, the normal state (default state) of the discrimination image 20 is "blue." If a jackpot is won in a special state, the discrimination image 20 becomes "red." A reset operation (as described above) is required to return the discrimination image 20 to "blue." In other words, the player cannot return it to "blue." This configuration allows for the explanation of the cause (the occurrence of a "puncture") to the player, even if a complaint arises because a jackpot won in a special state turns out to be a normal jackpot.

3) Promotion演出 3-1) Special Image Among the jackpots installed in the gaming machine 1 according to this embodiment, the special specific jackpot (10R) is the jackpot with the highest expected value of profit obtained by the player (the highest value). During the game of the special specific jackpot, a special image 30 representing a predetermined performance element is displayed. In this embodiment, a special image 30 representing a predetermined character (special character; indicated by the letter "X" in the drawings) is displayed (see Figure 20(c)). The appearance of the special image 30 may change within a range that the player can recognize as representing the same object. In other words, anything within the range that the player can recognize as representing the same object is considered a special image 30.

The special image 30 is not displayed during other types of jackpot games. Therefore, the special image 30 symbolizes the special jackpot and emphasizes (congratulates) the acquisition of the highest-value jackpot. It is preferable to display the special image 30 as early as possible. In this embodiment, the special image 30 is displayed upon a V-win (see Figure 20(b) → (c)). This further emphasizes that the V-win led to the acquisition of a special jackpot.

Furthermore, the special image 30 does not directly indicate a special jackpot. For example, it does not include part or all of the name (title) of the special jackpot. Also, the special image 30 is not displayed in one special jackpot game but not in another. In this embodiment, the special image 30 is displayed in both special jackpot games obtained during normal gameplay and special jackpot games obtained during specific gameplay states. Moreover, the special image 30 does not indicate the profit (payout) or number of rounds obtained during the special jackpot.

3-2) Special Upgrade Performance The gaming machine 1 according to this embodiment may perform an upgrade performance as part of the performance that constitutes the in-spin performance (winning spin) when the result of the win/loss lottery is a win (minor win). In this embodiment, the upgrade performance may occur during a winning spin in the normal game state (excluding the remaining reserve chance). However, this does not preclude the possibility of a performance that is substantially the same as the upgrade performance described below occurring in a specific game state.

As described above, in this embodiment, the types of jackpots that can be obtained through the first win/loss lottery in the normal game state (excluding the remaining reserve chance) are three types: normal jackpot (2 rounds), first specific jackpot (2 rounds), and special specific jackpot (10 rounds). Considering the number of rounds in the jackpot game and the game state transitioned to after the jackpot game ends, the expected value of the profit (hereinafter sometimes simply referred to as profit) obtained by the player from winning each jackpot is in the order of special specific jackpot > first specific jackpot > normal jackpot. In other words, the special specific jackpot is the most valuable jackpot for the player, and the normal jackpot is the least valuable jackpot for the player.

The promotion sequence involves the three types of jackpots mentioned above, but not the second specific jackpot. Therefore, for the purpose of the promotion sequence, the three types of jackpots are categorized (defined) as shown in Figure 21(a). Specifically, the special specific jackpot (10R) is defined as a "special jackpot," and jackpots not included in this "special jackpot" are defined as "non-special jackpots." Therefore, the regular jackpot (2R) and the first specific jackpot (2R) are included in the "non-special jackpot" category. Furthermore, the regular jackpot (2R) and the first specific jackpot (2R), which are "non-special jackpots," are defined as the first non-special jackpot and the second non-special jackpot, respectively. Arranged in order of increasing profit, the order is: First Non-Special Jackpot < Second Non-Special Jackpot < Special Jackpot.

As shown in Figure 21(b), in this embodiment, in the normal game state, if a winning combination of the "7" decorative symbol 80 (hereinafter referred to as a special combination) is displayed as confirmed, it is confirmed that a special jackpot will be won. In other words, there is no possibility that the jackpot won will be a non-special jackpot. Combinations other than the special combination are called non-special combinations. In this embodiment, the second non-special combination and the first non-special combination may be displayed as non-special combinations. The second non-special combination is a winning combination of odd-numbered decorative symbols 80 other than "7" ("1", "3", "5", "9"). If the second non-special combination is displayed as confirmed, there is no possibility that the jackpot won will be a first non-special jackpot. In other words, it is determined that the jackpot won will be a special jackpot or a second non-special jackpot (a second non-special jackpot or better). The first non-special combination is a winning combination of even-numbered decorative symbols 80 ("2", "4", "6", "8"). If the first non-special combination is displayed as confirmed, there is a possibility of any of the three jackpots (a first non-special jackpot or better). Therefore, from the player's perspective, special combinations are the most valuable, and the first non-special combination is the least valuable. Note that "confirmed display" refers to the display at the end of the reel spinning animation (the display at the point when the reel spinning of the 80 decorative symbols has completely stopped). In contrast, "provisional display" as used in the following explanation refers to a display during the reel spinning animation when the reel spinning of the 80 decorative symbols has not completely stopped (a state where they are slightly shaking, etc., not completely stopped). If a winning combination is provisionally displayed, the result of the win/loss lottery is considered confirmed to be a win. Furthermore, after a certain type of winning combination (special combination or second non-special combination) is provisionally displayed, it will not change to a lower-value winning combination and be confirmed (there is no rank down of winning combinations).

As mentioned above, if a winning combination is tentatively displayed during the reel spin animation, the result of the win/loss lottery is confirmed to be a win. In this embodiment, if a non-special combination (second non-special combination or first non-special combination) other than "7" is tentatively displayed (see Figure 22(a)), the result of the win/loss lottery is confirmed to be a win, but it is uncertain whether a special jackpot will be won. In such a situation, a special upgrade animation, which is a type of upgrade animation, may occur.

The special upgrade animation consists of a first and second half. The first half describes a state where it is uncertain whether a special jackpot can be won. Specifically, after a non-special combination (second non-special combination or first non-special combination) is temporarily displayed (pseudo-stopped) (see Figure 22(a)), the decorative symbols 80 are displayed in a changing manner (re-changing) (see Figure 22(b)). This constitutes the first half. The second half indicates that a special jackpot can now be won. In this embodiment, the special image 30 (an image representing a special character) is displayed in the second half (see Figure 22(c)), and then the re-changing of the decorative symbols 80 stops, confirming the special combination (see Figure 22(d)).

Thus, during the special promotion sequence, the special image 30 is displayed, just as during a special jackpot (special specific jackpot). The special image 30 (special character) is an image symbolizing the special jackpot (a character associated with the special jackpot). By displaying this special image 30 during the special promotion sequence, the content of the promotion sequence (special promotion sequence) and the jackpot (special jackpot) obtained through it are linked, creating a visual effect.

Furthermore, there are cases where a special combination is confirmed and a special jackpot is announced without a special promotion animation occurring. In other words, even if special image 30 is not displayed during the reel spin animation, there is still a possibility of winning a special jackpot.

3-3) Normal Upgrade Performance As described above, if a winning combination is tentatively displayed during the variation performance, it is confirmed that the result of the win/fail lottery is a win. In this embodiment, if the first non-special combination is tentatively displayed, it is confirmed that the result of the win/fail lottery is a win, but it is uncertain whether a second non-special jackpot or a special jackpot can be obtained (the jackpot obtained may be the first non-special jackpot). In such a situation, not only the special upgrade performance described above, but also an upgrade performance different from the special upgrade performance (referred to as a normal upgrade performance to distinguish it from the special upgrade performance in which the special image 30 is displayed) may occur.

The normal upgrade animation consists of a first and second half. The first half describes a state where it is uncertain whether a second non-special jackpot can be won (or even whether a special jackpot can be won). Specifically, the first half involves the first non-special combination being temporarily displayed (pseudo-stopped) (see Figure 23(a)), followed by the decorative symbols 80 changing and being displayed again (re-changing) (see Figure 23(b)). The second half indicates that a second non-special jackpot can now be won. In this embodiment, the second half involves the decorative symbols 80 stopping their re-changing and the second non-special combination being displayed (see Figures 23(c) and (d)).

In this case, the special image 30 is not displayed during a normal upgrade animation (see Figures 23(c) and 23(d)). Since the special image 30 symbolizes a special jackpot, and the normal upgrade animation does not indicate that a special jackpot is possible (it is not an animation that guarantees a special jackpot), the special image 30 is not displayed. This clarifies the difference between the special upgrade animation and the normal upgrade animation (the difference in the jackpots that can be obtained in the future).

3-4) Promotion Failure Animation The above promotion animations (special promotion animation, normal promotion animation) are animations in which the symbol combination displayed in the second half is a higher value symbol combination than the symbol combination displayed in the first half. In contrast, in the promotion failure animation, the symbol combination displayed in the first half (see Figure 24(a)) remains the same and is displayed in the second half after a re-spin (see Figure 24(b)) (no "promotion" of the symbol combination occurs) (see Figure 24(d)). In this embodiment, as a promotion failure animation, patterns may occur in which the first non-special combination is displayed in the first half and the first non-special combination is displayed in the second half, and in which the second non-special combination is displayed in the first half and the second non-special combination is displayed in the second half. Naturally, the special image 30 is not displayed in the promotion failure animation either.

3-5) In this embodiment, during a jackpot game (during a round), a "jackpot upgrade" may be announced. Hereinafter, this upgrade announcement will be referred to as a "jackpot upgrade." However, the upgrade animation described above is performed during the reel spin and is separate from the jackpot upgrade. If the second non-special combination is confirmed, a jackpot upgrade may occur to announce that the acquired jackpot was a special jackpot. If the first non-special combination is confirmed, a jackpot upgrade may occur to announce that the acquired jackpot was a special jackpot, and another jackpot upgrade may occur to announce that it was a second non-special jackpot. The specific form of these jackpot upgrades may vary, so a detailed explanation is omitted.

The occurrence of such a jackpot upgrade means that the confirmed symbol combination only guarantees at least one jackpot corresponding to that combination. As shown in Figure 21(b), the confirmation of the second non-special combination indicates that a jackpot of the second non-special jackpot or higher (second non-special jackpot or special jackpot) has been confirmed. The confirmation of the first non-special combination indicates that a jackpot of the first non-special jackpot or higher (first non-special jackpot, second non-special jackpot, or special jackpot) has been confirmed.

However, it is also possible to prevent such upgrades during a jackpot from occurring. In this case, when a certain combination of symbols is displayed as confirmed, the acquisition of the corresponding jackpot is determined. That is, if a special combination is displayed as confirmed, a special jackpot is acquired; if a second non-special combination is displayed as confirmed, a second non-special jackpot is acquired; and if a first non-special combination is displayed as confirmed, a first non-special jackpot is acquired. From another perspective, the occurrence of an upgrade animation (special upgrade animation, normal upgrade animation) represents the last chance for the type of jackpot to rank up (rank up from the provisional display).

The following describes specific examples that improve, modify, or elaborate upon the above-mentioned promotion animations. Furthermore, where possible, a configuration that applies multiple aspects of the specific examples described below may be used.

○Specific Example 2-1
In the above embodiment, it was explained that the special jackpot (special specific jackpot) is the jackpot with the highest expected value of profit obtainable by the player among multiple types of jackpots (the highest jackpot). However, the configuration may be such that the special jackpot is not the highest jackpot.

○Specific Example 2-2
The system is configured to display a special image 30 when a jackpot upgrade (upgrade during a round) occurs. For example, suppose a non-special combination (first non-special combination or second non-special combination) is confirmed and displayed (see Figure 25(a)), and then the jackpot game begins (see Figure 25(b)). If a jackpot upgrade occurs during that jackpot game, indicating that the acquired jackpot was a special jackpot, then the special image 30 will be displayed (see Figure 25(c)). In other words, at the start of the jackpot game, it appears as if the acquired jackpot was not a special jackpot, and then, when it is announced that the acquired jackpot was actually a special jackpot during the jackpot game, the special image 30, which symbolizes a special jackpot, is displayed to emphasize this. In this way, it is possible to clearly indicate that a special jackpot has been acquired (that it has been upgraded to a special jackpot).

○Specific Examples 2 and 3
The special image 30 shown above is displayed in special jackpot games obtained during normal gameplay (excluding remaining reserve chances), i.e., in special jackpot games obtained as a so-called "first win," but is not displayed in special jackpot games obtained in specific gameplay states. In other words, it is displayed in special jackpot games obtained after winning a low-probability lottery, but is not displayed in special jackpot games obtained after winning a high-probability lottery.

As mentioned above, the promotion animation (special promotion animation) can occur during a winning spin when the first win/loss lottery is won in the normal game state (excluding the remaining reserve chance). Therefore, it will only be displayed for special jackpot games that are "first wins" obtained in the normal game state. In other words, the situation in which the special promotion animation, in which special image 30 is displayed, can occur, and the situation in which a special jackpot, in which special image 30 is displayed, can be obtained, will be the same (normal game state). By doing so, the connection between the content of the promotion animation (special promotion animation) and the jackpot (special jackpot) obtained through it can be made clearer.

○Specific Example 2-4
In the above embodiment, the special upgrade animation displays the special image 30 automatically (regardless of the player's actions). In contrast, this configuration ensures that the special image 30 is not displayed in the special upgrade animation unless predetermined conditions are met by the player's actions. For example, if an operating means 60 (see Figure 1), such as a push button, is operated during a predetermined period set during the re-spin after a non-special combination has been provisionally displayed (a period set before the confirmed display is made), a lottery (display lottery) is executed as a result, and the special image 30 is displayed on the condition that the player wins the display lottery (see Figure 26(a) → (b-1)). If the player does not win the display lottery, the special image 30 is not displayed (see Figure 26(a) → (b-2)). Naturally, if the operating means 60 is not operated at all, the special image 30 will not be displayed. Regardless of whether the player wins the display lottery or not, the special combination is ultimately confirmed and displayed (see Figure 26(c)). In other words, whether or not you win the display lottery (whether or not special image 30 is displayed) is merely a visual difference and does not affect the actual profit (payout).

By using this example, it is possible to create a special upgrade animation that gives the impression that the player has, through their own efforts, displayed the special image 30, which symbolizes a special jackpot.

○Specific Example 2-5
In the above embodiment, it was explained that the special image 30 displayed during the special jackpot game is also displayed in the special upgrade animation, meaning that a common "image" is displayed. However, other performance elements (output elements that can be perceived by the player's senses) may also be common. For example, the sound output from the speaker 65 (see Figure 1) (hereinafter referred to as the special sound) may be common. That is, the special sound output during the special jackpot game (see Figure 27) will also be output in the special upgrade animation (see Figure 28). Note that the special sound is not output during other jackpot games. In this way, the sound symbolizing the special jackpot will also be output in the special upgrade animation, making it easier to understand that the special upgrade animation suggests the acquisition of a special jackpot.

Preferably, the special sound output during a special jackpot game should be triggered by a V-win (see Figure 27(b) → (c)). This makes the special sound a "prominent sound" that signals the acquisition of a special jackpot (V-win). By outputting such a "prominent sound" during special upgrade sequences, it becomes clearer that the special upgrade sequence indicates the acquisition of a special jackpot.

4) Although embodiments of the present invention have been described in detail above, the present invention is not limited in any way to the above embodiments, and various modifications are possible without departing from the spirit of the invention.

The gaming machine 1 according to the above embodiment is described as having a so-called "Type 2" gameplay, where a big win can be obtained via a small win. However, except for configurations that are only possible with this "Type 2" gameplay, the configurations described in the above embodiment can also be applied to gaming machines with "Type 1" gameplay (gaming machines equipped with so-called direct wins, including Type 1 and Type 2 hybrid machines). For example, the "promotion effect" described above can also be applied to gaming machines with "Type 1" gameplay.

The specific means (gaming machines) obtained from the above embodiments are listed below.

○Means 1-1
A gaming machine comprising: a win/loss lottery means that performs a win/loss lottery based on win/loss lottery information acquired when a game ball enters a starting area; a variation performance execution means that performs variation performances from when multiple types of decorative symbols start to vary until they stop in a manner corresponding to the win/loss lottery result; and a game state setting means that can set a normal game state and a specific game state which is a high opening/closing mode in which it is easier for a game ball to enter the starting area than in the normal game state, wherein the specific game state is provided as a first specific game state and a second specific game state, and the game is characterized by having a combination of a count-limited type of gameplay in which, when transitioning to the first specific game state, the condition for avoiding transitioning to the normal game state is to win a jackpot before the win/loss lottery result is a loss for a specified number of consecutive times, and a loop type of gameplay in which, when transitioning to the second specific game state, the condition for avoiding transitioning to the normal game state is that the next jackpot, which is effectively guaranteed to be won, is not a normal jackpot.
The above-mentioned gaming machine is an innovative design that combines the gameplay features of both a limited-play-per-turn type and a loop-type gameplay.

○Means 1-2
The gaming machine according to means 1-1, further comprising a storage means for storing a predetermined number of win/loss lottery information, for which the corresponding variable performance has not yet been initiated, as reserved information, and characterized in that, when the win/loss lottery result is a predetermined number of times consecutively unsuccessful in the first specific game state and the game transitions to the normal game state, the condition for transitioning to the second specific game state is that a jackpot is won based on the reserved information stored in the storage means.
This approach creates an innovative gameplay experience where winning a jackpot with the remaining reserved spins is the condition for transitioning to the second specific game state.
Furthermore, even if the first specific game state ends, there is a chance to transition to the second specific game state, resulting in an engaging gameplay experience.

○Means 1-3
A jackpot can be won by entering a special area that is opened when the result of the draw is a minor win, and there are two types of jackpots: a first specific jackpot which transitions to the first specific game state after the jackpot game ends, and a second specific jackpot which transitions to the second specific game state after the jackpot game ends.
The first specific game state is characterized in that, after it is started, the high opening/closing mode does not end upon winning one minor prize, whereas the second specific game state is characterized in that, after it is started, the high opening/closing mode ends upon winning one minor prize, and if the game ball enters the bonus area at the time the high opening/closing mode is in effect, there is a possibility that the jackpot won is the first specific jackpot, and if the high opening/closing mode is not in effect, there is a possibility that the jackpot won is the second specific jackpot, according to means 1-1 or means 1-2 of the game machine.
In this way, by ensuring that the high opening/closing mode does not end upon winning a minor prize in the first specific game state, and that the high opening/closing mode ends upon winning a minor prize in the second specific game state, the types of big wins that can be obtained can be made different in the first and second specific game states.

○Means 1-4
The gaming machine according to means 1-3, wherein a special specific gaming state is provided in which the next big win, which is effectively guaranteed to be won, is not the regular big win, and the high opening/closing mode does not end when a small win is achieved after the special specific gaming state has started.
The second specific game state and the special specific game state are similar in that the next big win is virtually guaranteed, but they differ in whether the high opening/closing mode ends when a minor win is achieved. Therefore, the types of big wins that can be obtained in the second specific game state and the special specific game state can be different.

○Means 2-1
A win/loss lottery means that performs a win/loss lottery based on win/loss lottery information acquired when a game ball enters the starting area; a bonus area which is opened when the win/loss lottery result is a minor win, and where the entry of a game ball is a condition for awarding a jackpot; an opening/closing mode setting means that can set a low opening/closing mode and a high opening/closing mode which makes it easier for a game ball to enter the starting area than when in the low opening/closing mode; and a means that determines the type of jackpot to be awarded depending on whether or not the high opening/closing mode is in place when a game ball enters the bonus area. A gaming machine comprising a means for determining a jackpot, wherein a first specific gaming state is provided in which the high opening/closing mode ends when a minor jackpot is won N times (N is 2 or more) after the start of play, and in the first specific gaming state, the manner of the target performance executed when a predetermined condition is met differs between a normal state before N-1 non-entry events occur in which a minor jackpot is won but the game ball does not enter the bonus area, and a special state after N-1 such non-entry events have occurred.
According to the above-mentioned gaming machine, the risk of complaints arising from the fact that a jackpot won in a special state differs from a jackpot won in a normal state can be reduced.

○Means 2-2
The aforementioned target performance is a performance in which a winning combination consisting of the same type of decorative symbols indicating that the result of the winning or losing lottery is a win is displayed, and the type of decorative symbols that make up the winning combination displayed in the normal state is different from the type of decorative symbols that make up the winning combination displayed in the special state, as described in means 2-1 of the gaming machine.
This emphasizes that the types of jackpots that can be won differ between the normal state and the special state (i.e., the method for determining the type of jackpot differs).

○Means 2-3
The gaming machine according to means 2-1 or means 2-2, characterized in that, when the non-entry event occurs N-1 times in the first specific gaming state, special information indicating that the special state is in place is stored in a non-volatile storage means.
This ensures that even if a power outage occurs and is restored, gameplay will resume in a special state (preventing the system from returning to its normal state due to the power outage).

○Means 2-4
The gaming machine according to means 2-1, characterized in that a second specific gaming state is provided, which is the high-opening/closing mode, and which ends when the high-opening/closing mode is triggered by winning a small prize once after the start of the game.
In this way, the method for determining the type of jackpot won can be different in the first specific game state and the second specific game state.

○Means 3-1
A gaming machine that has multiple types of jackpots, including a special jackpot, which can be won when the result of the win/fail lottery is a win, and which is capable of executing an upgrade sequence as part of the in-spin sequence for winning, from when multiple types of decorative symbols start to spin until they stop in a manner that indicates the result of the win/fail lottery is a win, and which is capable of executing a special upgrade sequence that transitions from a state in which it is uncertain whether the special jackpot can be won to a state in which it is possible to win the special jackpot, and which is characterized in that a special image representing a predetermined performance element is displayed during the special upgrade sequence and during the special jackpot.
In the aforementioned gaming machine, the special upgrade animation and the special jackpot are linked by a common visual element—a special image—making it easy to understand that the two are linked (the target of the special upgrade animation is the special jackpot).

○Means 3-2
The gaming machine according to means 3-1, wherein there are two or more non-special jackpots, the expected value of the profit that the player can obtain is lower than that of the special jackpot, the two or more non-special jackpots include a first non-special jackpot and a second non-special jackpot, the expected value of the profit that the player can obtain is higher than that of the first non-special jackpot, and as the upgrade performance, a normal upgrade performance can be executed, which transitions from a state in which it is uncertain whether it is possible to obtain the second non-special jackpot to a state in which it is possible to obtain the second non-special jackpot, and the special image is not displayed during the normal upgrade performance.
This makes it clear that the target of the regular promotion animation is not a special jackpot.

○Means 3-3
The gaming machine according to means 3-1 or means 3-2, characterized in that the special jackpot is the jackpot with the highest expected value of profit obtainable by the player among multiple types of jackpots that can be obtained.
In this way, the special image functions as an element that emphasizes (symbolizes) the fact that the highest-value jackpot has been won.
