Description

  In the present invention, a plurality of reels (rotors) that start rotating by a start operation after the game medium is inserted, and a pattern such as a picture, a character, etc. attached to each reel after a constant speed rotation is predetermined on the winning line. With regard to slot machines (revolving game machines) that acquire a certain amount of winning game media (prize balls) by stopping to be arranged, especially according to the number of game media inserted (game media bet number, prescribed number) The present invention relates to a slot machine that changes the internal lottery probability for each gaming state and realizes a bonus high probability state in a predetermined specific gaming state.

In general, in a slot machine, when a player inserts a game medal (coin) as a game medium and presses a start lever, a plurality of ( (Normally 3) reels start rotating, and after rotating at a constant speed, the reels stop when the stop button is pressed at an arbitrary timing, and a predetermined number of game media are paid out according to the arrangement of the symbols of the stopped reels. Is a gaming machine.
In such a slot machine, normally, in order to increase the fun of the game, a plurality of reels are automatically controlled with a certain probability so that the symbols attached to each reel are arranged in a predetermined arrangement on the winning line. A so-called “internal lottery” winning control that stops is performed.

In this internal lottery control, when the game is started by pressing the start lever, the internal winning lottery is automatically performed in the slot machine for each game, and the winning content is determined. The reel stop position is controlled, and if the result of the lottery is hit, regardless of the timing when the player presses the stop button, the symbols attached to each reel within a certain range will correspond to the winning content. Then, stop control is automatically performed so that the arrangement (winning arrangement) is achieved (slip), and a predetermined amount of game media corresponding to the winning arrangement is paid out.
More specifically, as a result of the internal lottery, if a certain content is hit, a plurality of rotating reels are within a certain range (for example, within the range of 4 symbols from the position of the corresponding symbol) and the player stops Regardless of the timing of pressing the button, the symbol is stopped on the predetermined winning line so that it becomes a predetermined winning arrangement (for example, “7, 7, 7”, “BAR, BAR, BAR”, etc.) according to the winning content. Control (winning control).

As a result of the reel stop control being performed in this manner, the timing of pressing the stop button of each reel deviates from the timing of stopping the symbols (“7”, “BAR”, etc.) constituting an array of a winning content on the array. Even if the deviation is within a certain range (within 4 frames from the symbol, etc.), the symbol is stopped by mechanical control so that the symbol is positioned on a predetermined winning line, and the winning arrangement is configured. Is done.
As a result of this stop control, regardless of the skill of the game, if the player presses the stop button within a certain range, the reels are automatically stopped so that the symbols are in a predetermined winning arrangement, and the stopped winning prize is A predetermined amount of game media is paid out according to the arrangement. As a result, even a beginner or a person unfamiliar with a game can acquire a predetermined amount of winning game media with a certain probability.

Here, in the slot machine game in which a predetermined amount of game media is paid out by the reel stop control as described above, a specific game advantageous to the player and a normal game that is a game other than the specific game are usually performed. It is like that.
A specific game (combination) is different from a normal game when a predetermined condition is established in that game or the next game or later when a predetermined “big hit” is won as a result of an internal lottery. One or a plurality of games are performed under control, and the specific gaming state is ended when a certain condition is satisfied.
For example, a specific game state that is advantageous to a player, so-called “bonus game” is known. Examples of the bonus game include “single bonus game (SB)”, “regular bonus game (RB)”, and “big bonus game (BB)”.

  As a result of the internal lottery, the single bonus game (SB) (hereinafter referred to as “single bonus (SB)” for short) “wins (flags established)” and the reels stop at the single bonus (SB) winning symbol. When “winning (start)” is performed, only the next game is in a specific gaming state, and when the reel is stopped at a predetermined winning symbol (for example, “JAC / JAC / JAC”) in the next game, a predetermined number of game media are stored. It is to be paid out. Note that the single bonus (SB) is a game corresponding to a normal character.

  In addition, as a result of the internal lottery, a regular bonus game (RB) (hereinafter referred to as “regular bonus (RB)”) or a big bonus game (BB) (hereinafter abbreviated) in which a large amount of game media can be paid out. If you win a bonus game such as “Big Bonus (BB)”), you wo n’t win until the reels have a predetermined winning arrangement (for example, “7.7.7”). When the reels stop at the winning symbol and “win (start)”, the game will be in a specific game state for one or several games thereafter, and a high play rate that cannot be obtained during normal games With this, the game medium is paid out.

Specifically, when a regular bonus (RB) is won or won, control is performed for a bonus game in which several games become one set. During the bonus game, a small role with a small payout or a large amount The lottery and reel are controlled so that a predetermined symbol arrangement with payout is continuously arranged, and, for example, 100 or more game media are paid out. Note that the regular bonus (RB) is a game corresponding to a first-class special bonus.
Further, when the big bonus (BB) is won or won, the above-mentioned regular bonus (RB) is controlled so that several sets (for example, three sets) are continued, and for example, hundreds of large numbers of game media are paid out. The game is controlled. Note that the big bonus (BB) is a game that corresponds to the first kind special feature continuous operation.

In addition to the single bonus (SB), regular bonus (RB), and big bonus (BB), the specific game (act) includes, for example, a single challenge time (SCT) and a challenge time (CT).
The single challenge time (SCT) is a gaming state in which at least one reel is controlled to stop according to the pressing timing of the stop button regardless of the result of the internal lottery, and only the next game is in that state. Say.
The reel stop control in the single challenge time (SCT) includes a control (so-called “bitter stop”) for stopping a symbol on the winning line as it is on the winning line when the stop button is pressed, Control that stops symbols within a predetermined number of symbols (for example, one frame, two frames, etc.) on the winning line from this symbol based on the symbols that were positioned on the winning line when the stop button was pressed (So-called “slip control”) and control for removing the symbol from the winning line and stopping it so that the symbol arrangement on the winning line does not become the predetermined winning arrangement (winning prevention control).

These stop controls are performed regardless of the result of the internal lottery. For example, even if the result of the internal lottery is “losing”, the symbols placed on the winning line at the time when the stop button is pressed are “small roles” because all three reels are “small roles”. If “Combination, Small Role, Small Role” is aligned (ie, if “Poor, Small Role, Small Role” is aligned with bittering), a prize will be awarded.
In addition, although the arrangement of the symbols placed on the winning line when the stop button was pressed was not “pocket, small bonus, small bonus”, the symbols were positioned on the winning line at the time of pressing. If there is a “pocket” within the range of the specified number of symbols with reference to, even if the result of the internal lottery is “lost”, the slip control is performed so that the “pocket” stops on the winning line This control is performed on all or a part of the three reels, and a winning combination is made when “small part, small part, small part” is arranged.
Furthermore, it means that the symbol array located on the winning line when the stop button is pressed wins the symbol array (for example, “7, 7, 7 ”etc.), the symbol (“ 7 ”) on one or more reels is removed from the winning line and stopped by winning prevention control to avoid the winning.

  In the single challenge time (SCT) in which such stop control is performed, the range of the number of symbols in which the slip control is performed is usually as small as one or two frames, and it depends on the result of the internal lottery. Since the reel stops almost in accordance with the timing of pressing the stop button, the gaming state is advantageous to skilled players who are good at stopping bitterness.

The challenge time (CT) refers to a gaming state in which a single challenge time (SCT) is played in a plurality of games until a predetermined payout number (for example, several hundreds) is reached or a predetermined condition is satisfied.
Note that the single challenge time (SCT) is a game corresponding to the second type special character. In addition, the challenge time (CT) is a game corresponding to the second kind special feature continuous operation.

In the above-described specific game (object), the predetermined symbols are controlled so as to be aligned on the winning line with a high probability, whereby a predetermined amount or a large amount of game media can be acquired.
As described above, in the conventional slot machine, control is performed so that a large amount of game media that is advantageous to the player is paid out in a specific game state generated by a big win (winning of a specific game (commodity)). Yes, this is the greatest feature of the slot machine (see, for example, Patent Document 1-2).

  On the other hand, the normal game refers to a game in a state where a specific game state has not started. Further, the normal game includes a game from the end of the specific game state to the start of the next specific game state. When the replay time (RT) is started after the big bonus (BB) ends, there is no normal game between the big bonus (BB) and the replay time (RT). In this case, the replay time (RT) ends and the next game or later becomes a normal game.

In this normal game, as a result of the internal lottery, “small role” in which a small amount of game media (for example, 2 cards, 7 cards, etc.) is paid out for each game, or the next game can be performed without game media being inserted. Stop control of “replay (RP)” and “losing” without paying out game media is performed. The effects of these lottery results are valid only for that game, and the effects disappear in subsequent games.
In general, in a slot machine game, except for specific games (combined items) that occur at a certain probability, the basic game is repeated in units of one game in principle.

  Also, in normal games, as a result of the internal lottery, the single bonus (SB), regular bonus (RB), big bonus (BB) (and, if equipped, single challenge time (SCT) or challenge time) (CT)) may be hit, and reel stop control is performed according to the contents of these wins. Here, with the stop control, when a predetermined game is aligned on the winning line and a specific game (combination) is won, the specific game state is started from the next game, and control that is advantageous to the player is performed. Is called. On the other hand, even if the reel stop control is performed, if the predetermined symbols are not aligned on the winning line and the specific game (combination) is not won, the specific game state is not started and the next game continues to be the normal game. A game is played depending on the state.

Incidentally, as described above, in a slot machine, an internal lottery is performed in accordance with a start operation, and the lottery probability of the internal lottery is determined by a predetermined lottery probability table.
Specific examples of the lottery probability table are shown in FIGS. The figure (a) is a specific example of the lottery probability for each gaming state in the three-bet dedicated machine (a gaming machine in which the number of betting of game media (medals) in a normal game is limited to three), (b) Is a specific example of a lottery probability for each gaming state in a 1 to 3 betting machine (a gaming machine in which the number of betting media (medals) in a normal game can be 1, 2, or 3). Is shown respectively.

As shown in FIGS. 4A and 4B, in both the three-wager dedicated machine and the one to three-wager machines, the lottery probability (1 / 10), replay (RP) drawing probability (1 / 7.3), big bonus (BB) drawing probability (1/500, etc.), regular bonus (RB) drawing probability (1/300, etc.), The drawing probability (1/1) of the small role in the big bonus (BB) and the drawing probability (1/1) of the small role in the regular bonus (RB) are respectively determined.
In addition, since the big bonus (BB) and the regular bonus (RB) are not drawn during the big bonus (BB) and the regular bonus (RB), the drawing probability is not determined.

Here, the drawing probability of the big bonus (BB) and the regular bonus (RB) capable of acquiring a large amount of game media is very low compared to the drawing probability of the small role or replay (RP). This is to prevent the player from gaining excessive profits due to frequent winning of big bonuses (BB) or the like.
Further, in the case of 1 to 3 betting machines, in a normal game, the lottery probability gradually decreases as the number of betting of game media (medals) decreases. In addition, the probability of drawing a single bet is very low compared to a 3-stake or 2-stake. This is determined so that a three-wager bet is advantageous to the player.

  However, in the conventional slot machine, the bonus game drawing probability is set to a certain low level, for example, about 1/300 or 1/500, so as not to excessively give the player gambling. For this reason, although the player expects to win or win a bonus game, the conventional slot machine cannot play a game while greatly increasing the degree of expectation.

Here, a so-called stock machine has been proposed as a state where a bonus is intentionally drawn with a high probability.
A stock machine is a gaming machine in which bonuses won are temporarily stored and later released together. Thereby, a pseudo high probability state can be created.
However, in the case of a stock machine, it was supposed to create a very unfair state for the player depending on whether or not the bonus stock was accumulated.

  In addition, some conventional slot machines are equipped with a single bonus (SB) or single challenge time (SCT) that has a higher drawing probability than a big bonus (BB) or regular bonus (RB). . However, these single bonuses (SB) etc. could not be linked to mass acquisition such as big bonuses (BB) because only the next game is played in a state advantageous to the player. . For this reason, the single bonus (SB) or the like has been regarded as an unattractive game compared to the big bonus (BB) or the like.

Furthermore, the low lottery probability such as the big bonus (BB) hinders the player's expectation to acquire a large amount of game media. That is, while the player desires to acquire a large amount of game media, the player cannot tend to win a big bonus (BB) or the like, and therefore has a tendency to think that a large amount of acquisition cannot be realized. Thus, if the player's interest in the slot machine is diminished, the game hall side is concerned that it may lead to a decrease in the number of visitors.
In order to improve the situation and encourage the players to visit and improve the occupancy rate, the gaming hall side is attractive to realize a gaming state in which the probability of lottery such as a big bonus (BB) is very high I wanted to offer a slot machine.

In addition, slot machine games have rapidly spread and expanded in recent years, and books showing game contents and strategies for various slot machines have been sold, and slot machine game systems that have been adopted so far. The game content and game system are already widely known and permeated among many players.
For this reason, from the viewpoint of continuously providing more attractive slot machines, the appearance and characters of the slot machine are changed in a certain cycle.
However, in order to maintain and expand the popularity of slot machine games by always providing players with fresh and interesting slot machine games, not only changes in the appearance and characters of slot machines, It has also become necessary to introduce a new lottery method that replaces the internal lottery method.

  The present invention was created as a result of the inventor's earnest research with careful consideration of each of the above circumstances, and the bonus probability of the bonus game can be increased by changing the lottery probability of each gaming state according to the number of bets on the gaming medium. Realizes the probability state and can improve the attractiveness of single bonus (SB) and single challenge time (SCT), and can realize a high probability state of the bonus game without creating an unfair situation for the player The purpose is to provide a slot machine full of new charm that never existed before.

  In order to achieve this object, the slot machine of the present invention stops a plurality of reels that start rotating by a start operation so that the symbols on each reel are in a predetermined winning arrangement, so that a game according to a winning symbol is achieved. It is a slot machine that pays out media, and storage means for storing an internal lottery table that determines the internal lottery probability for each game, and internal lottery based on the lottery probability set in the internal lottery table Control means for controlling each game to be played in either a normal gaming state or a specific gaming state according to the result of the lottery, and the internal lottery table is specified in a predetermined number of gaming medium bets. The lottery probability of the game state is set higher than the lottery probability of the specific game state in other game medium bets, and the control means The predetermined game medium bet number increases, there only a configuration in which receivable controlled in predetermined specific gaming state.

When the slot machine has such a configuration, it is possible to realize a high probability state of the bonus game by changing the lottery probability of each gaming state according to the number of betting of the game medium.
For example, the lottery probability of the specific gaming state at the game medium bet number “1” is set higher than the lottery probability of the specific gaming state at the game medium bet number “3”. The game medium bet number “1” can be accepted only in a predetermined specific gaming state (for example, a single bonus (SB)). Thereby, the lottery probability of each gaming state is changed according to the number of gaming medium bets, and a high probability state of a specific gaming state in a predetermined specific gaming state can be realized.
Here, the lottery probability of the specific gaming state in the predetermined specific gaming state can be set to be significantly higher than the lottery probability of the specific gaming state in the conventional slot machine. For this reason, the present invention can provide a slot machine full of new appeal that has never existed before.

  Moreover, the high probability state of the bonus game in the slot machine of the present invention is different from the pseudo high probability state in the conventional stock machine, and the internal lottery is actually performed with high probability. Therefore, it is possible to realize a slot machine that can eliminate unfairness to the player and experience a true high probability state.

Furthermore, since the number of game medium bets varies according to the game state, the player can easily grasp the current game state.
For example, the number of game media bets in the single bonus (SB) is “1”. In this case, the player cannot insert two or more game media. For this reason, the player can easily grasp that the current gaming state is in operation of the single bonus (SB).

  In the slot machine of the present invention, the specific game state includes a plurality of first and second specific game states, and the internal lottery table has the first and / or second specific number in a predetermined number of game medium bets. The gaming state betting probability is set higher than the first and / or second specific gaming state betting probabilities for other gaming medium betting numbers, and the control means sets the predetermined gaming medium betting number to the first and / or The configuration is such that the reception is allowed only in a predetermined specific gaming state including the second specific gaming state.

If the slot machine has such a configuration, the lottery probability of each gaming state is changed according to the number of bets on the gaming medium, and the specific gaming state in one or both of the first and second specific gaming states is high. Probability states can be realized.
For example, the predetermined number of game media bets is “1”, the number of other game media bets is “3”, the first specific game state is a single bonus (SB), and the second specific game state is a big bonus ( BB) and the predetermined specific gaming state is a single bonus (SB), the predetermined game medium bet number “1” can be accepted only in the predetermined specific gaming state (single bonus (SB)). If a single bonus (SB) is won or won in the normal gaming state, then a single bonus (SB) in which one or both of the single bonus (SB) and the big bonus (BB) have a high probability of drawing will be given. It can be carried out.

Furthermore, since the lottery probability of the first specific gaming state in the first specific gaming state is high, once the first specific gaming state is won or won, any number of games will continue in succession. It is also possible to continue winning in the first specific gaming state. In addition, during the first specific game state, the lottery probability of the second specific game state is also high. As a result, while the first specific gaming state continues, the expectation for winning or winning the second specific gaming state increases, and multiple games can be played while maintaining this high expectation and tension. You can continue.
In this way, if the transition is made from the normal gaming state to the first specific gaming state, the lottery probability of the second specific gaming state (bonus game) will increase, so expectation of winning a bonus game due to the transition of the gaming state A feeling can be raised.

Furthermore, as described above, for example, if the first specific gaming state is a single bonus (SB), the attractiveness of the single bonus (SB) can be improved.
In the conventional single bonus (SB), only the next game becomes a bonus game, and when this is finished, the game is in the normal gaming state again. On the other hand, in the slot machine of the present invention, if the first specific gaming state is a single bonus (SB), in principle, only the next game will be a bonus game. Since the probability is high, a single bonus (SB) bonus game can be continuously performed with a high probability. Moreover, while this single bonus (SB) continues, the probability of drawing in the second specific gaming state is high, and the player can be expected to win in the second specific gaming state. . For this reason, the charm of the single bonus (SB) can be dramatically improved over the conventional single bonus (SB).

  Furthermore, in the slot machine of the present invention, the same can be said for the single challenge time (SCT) as for the single bonus (SB). In other words, if the first specific game state is a single challenge time (SCT), it is possible to perform this single challenge time (SCT) continuously with a high probability. The expectation of winning the state can be greatly enhanced. Therefore, the attractiveness of the single challenge time (SCT) as well as the single bonus (SB) can be dramatically improved.

In the slot machine of the present invention, at least one of the specific gaming states is a single bonus game.
If the slot machine has such a configuration, the probability of drawing a single bonus (SB) for a predetermined number of game media bets can be set higher than the probability of drawing a single bonus (SB) for other numbers of game media bets. The predetermined number of game medium bets can be accepted only in a predetermined specific game state (for example, a single bonus (SB)). Further, the lottery probability of other specific gaming states (for example, big bonus (BB)) in the single bonus (SB) is determined to be higher than the lottery probability of other specific gaming states in the normal gaming state. As a result, when a single bonus (SB) is won or won, a gaming state with a high lottery probability such as a big bonus (BB) is obtained, and a high probability state of the bonus game can be realized.

The slot machine of the present invention is configured such that at least one of the specific gaming states is a big bonus game.
If the slot machine has such a configuration, the probability of big bonus (BB) drawing in a predetermined number of gaming media bets can be set higher than the probability of drawing big bonus (BB) in other numbers of gaming media bets. . The predetermined number of game medium bets can be accepted only in a predetermined specific game state (for example, a single bonus (SB)). As a result, when a single bonus (SB) or the like is won or won, the gaming state has a high probability of drawing a big bonus (BB), and a high probability state of a big bonus (BB) can be realized.

The slot machine of the present invention is configured such that at least one of the specific gaming states is a regular bonus game.
When the slot machine has such a configuration, the probability of drawing a regular bonus (RB) at a predetermined number of game media bets can be set higher than the probability of drawing a regular bonus (RB) at other numbers of game media bets. The predetermined number of game medium bets can be accepted only in a predetermined specific game state (for example, a single bonus (SB)). As a result, when a single bonus (SB) or the like is won or won, a gaming state with a high probability of drawing a regular bonus (RB) is achieved, and a high probability state of a regular bonus (RB) can be realized.

The slot machine of the present invention is configured such that at least one of the specific gaming states is a single challenge time.
If the slot machine has such a configuration, a single challenge time (SCT) draw probability for a predetermined number of game media bets is set higher than a single challenge time (SCT) draw probability for other game media bets. Can do. The predetermined number of game medium bets can be accepted only in a predetermined specific game state (for example, single challenge time (SCT)). Furthermore, the lottery probability of other specific gaming states (for example, big bonus (BB)) in the single challenge time (SCT) is set higher than the lottery probability of other specific gaming states in the normal gaming state. As a result, when a single challenge time (SCT) is won / winned, a gaming state with a high lottery probability such as a big bonus (BB) is obtained, and a high probability state of a bonus game can be realized.

The slot machine of the present invention is configured such that at least one of the specific gaming states is a challenge time.
When the slot machine has such a configuration, the probability of challenge time (CT) drawing in a predetermined number of game media bets can be set higher than the probability of challenge time (CT) in other game media bets. The predetermined number of game medium bets can be accepted only in a predetermined specific game state (for example, a single bonus (SB)). Thereby, a game state with a high challenge time (CT) drawing probability is obtained by winning and winning a single bonus (SB) or the like, and a high probability state with a challenge time (CT) can be realized.

Furthermore, the lottery probability of a predetermined specific gaming state (for example, single bonus (SB)) in the challenge time (CT) can be set higher than the lottery probability of the predetermined gaming state in the normal gaming state. The lottery probability of another specific gaming state (for example, big bonus (BB)) in the predetermined specific gaming state can be set higher than the lottery probability of the other specific gaming state in the normal gaming state.
Therefore, a game state with a high probability of drawing a bonus game can be realized by winning / winning a challenge time (CT) and then winning / winning a predetermined specific gaming state, thereby realizing a high probability state of the bonus game. .

  In the slot machine according to the present invention, the first specific game state is a single bonus game, the second specific game state is a big bonus game and / or a regular bonus game, and the internal drawing table has a predetermined table. The probability of single bonus game lottery at a certain number of game media bets is set to be higher than the single bonus game draw probability at other game media bets, and the bonus bonus and / or regular bonus game at a predetermined game media bet The lottery probability is set higher than the lottery probability of the big bonus game and / or the regular bonus game in other game medium betting numbers, and the control means sets the predetermined game medium bet number to a predetermined specific game state including a single bonus game. To accept only in There as formed.

If the slot machine has such a configuration, the single bonus (SB) drawing probability in the single bonus (SB) can be set higher than the single bonus (SB) drawing probability in the normal gaming state. In addition, it is possible to set the drawing probability of the big bonus (BB) or the regular bonus (RB) in the single bonus (SB) higher than the drawing probability of the big bonus (BB) or the regular bonus (RB) in the normal gaming state.
Therefore, a winning state of a bonus game can be realized because a game state with a high drawing probability of a big bonus (BB) or a regular bonus (RB) is achieved by winning / winning a single bonus (SB).
Note that specific examples of such game characteristics will be described in detail in (Type a) to (Type d) in [Best Mode for Carrying Out the Invention] below.

In the slot machine of the present invention, the big bonus game includes a big bonus game in which a replay time is continued after the end of the big bonus game.
When the slot machine has such a configuration, it is possible to set a high probability of drawing a big bonus (BB) (second big bonus (BB2)) with a replay time (RT) among the big bonuses (BB).
As described above, since a game state with a high lottery probability of a big bonus (BB) with a replay time (RT) is obtained by winning or winning a predetermined specific gaming state (for example, a single bonus (SB)), a bonus game High probability state can be realized.
A specific example of such game characteristics will be described in detail later in (Type d) of [Best Mode for Carrying Out the Invention].

  In the slot machine of the present invention, the first specific gaming state is a single bonus game, the second specific gaming state is a single challenge time, and the third specific gaming state is a big bonus game and / or Or a regular bonus game, the internal lottery table shows the single bonus game and / or single challenge time draw probability at a predetermined number of game media bets, the single bonus game and / or single challenge time at other game media bets The lottery probability of a big bonus game and / or a regular bonus game at a predetermined number of game media bets is set to be higher than the draw probability of a big bonus game and / or a regular bonus game at other game media bets. High set, control means, a predetermined game media bet number is as only the configuration of admissible controlled in predetermined specific game state including single bonus game and / or single challenge time.

  If the slot machine is configured in this way, the single bonus (SB) and single challenge time (SCT) drawing probability in the single bonus (SB) is set as the single bonus (SB) and single challenge time (SCT) in the normal gaming state. In addition, a single bonus (SB) and single challenge time (SCT) drawing probability in the single challenge time (SCT) can be set higher than a single bonus (SB) and single challenge time in the normal gaming state. It can be set higher than the lottery probability of (SCT). For this reason, when a single bonus (SB) is won, for example, in the normal gaming state, the single bonus (SB) and single challenge time (SCT) are drawn with a high probability in the next single bonus (SB). If you win or win a single challenge time (SCT), the next single challenge time (SCT) will be held. In the single challenge time (SCT), the single bonus (SB) and the single challenge time (SCT) are drawn with a high probability. If the single bonus (SB) is won and won, A single bonus (SB) is performed. Thus, once winning the single bonus (SB) or single challenge time (SCT), both the single bonus (SB) and the single challenge time (SCT) are in a high probability state, and thereafter, the single bonus (SB) The game can be advanced while repeating SB) and single challenge time (SCT).

  Moreover, in the single bonus (SB), since the probability of drawing the single bonus (SB) is high, the single bonus (SB) can be won or won during the single bonus (SB), and the single bonus (SB) can be continued. It becomes possible. Then, by continuously performing the single bonus (SB), the high probability state of both the single bonus (SB) and the single challenge time (SCT) is maintained. On the other hand, the same can be said for the single challenge time (SCT) as for the single bonus (SB). That is, the single challenge time (SCT) can be continuously performed because the probability of drawing the single challenge time (SCT) in the single challenge time (SCT) is high. The single challenge time (SCT) is continuously performed, so that a high probability state of the single challenge time (SCT) and the single bonus (SB) is maintained. Therefore, once a single bonus (SB) or single challenge time (SCT) is won, the game can be advanced while the single bonus (SB) and the single challenge time (SCT) are alternately repeated.

And the drawing probability of the big bonus (BB) or the regular bonus (RB) in the single bonus (SB) or the single challenge time (SCT) is larger than the drawing probability of the big bonus (BB) or the regular bonus (RB) in the normal gaming state. Is set to a high value, a high probability state of a big bonus (BB) or a regular bonus (RB) can be realized.
A specific example of such game characteristics will be described in detail later in (Type c) of [Best Mode for Carrying Out the Invention].

  In the slot machine of the present invention, the first specific gaming state is a single bonus game, the second specific gaming state is a challenge time, and the third specific gaming state is a big bonus game and / or It consists of regular bonus games, and the internal lottery table shows the single bonus game and / or challenge time draw probability for a given number of game media bets, and the single bonus game and / or challenge time draw probability for other game media bets. And the probability of drawing a big bonus game and / or regular bonus game at a predetermined number of game media bets is set higher than the probability of drawing a big bonus game and / or regular bonus game at another number of game media bets. The control means Game media bet number constant, there as only the configuration of admissible controlled in predetermined specific game state including single bonus game and / or challenge time.

  If the slot machine has such a configuration, the single bonus (SB) and challenge time (CT) drawing probability in the single bonus (SB) is the same as the single bonus (SB) and challenge time (CT) drawing probability in the normal gaming state. Furthermore, the probability of drawing a single bonus (SB) in the challenge time (CT) can be set higher than the probability of drawing a single bonus (SB) in the normal gaming state. For this reason, if a single bonus (SB) is won in the normal gaming state, for example, the single bonus (SB) and challenge time (CT) are drawn with high probability in the next single bonus (SB). If you win or win the challenge time (CT), the challenge time (CT) will be performed next. In this challenge time (CT), the single bonus (SB) is drawn with a high probability, and if the single bonus (SB) is won or won, the single bonus (SB) is then performed. . Thus, once winning the single bonus (SB), both the single bonus (SB) and the challenge time (CT) are in a high probability state, and thereafter the single bonus (SB) and the challenge time (CT). You can continue playing the game while repeating.

  Moreover, in the single bonus (SB), since the probability of drawing the single bonus (SB) is high, the single bonus (SB) can be won or won during the single bonus (SB), and the single bonus (SB) can be continued. It becomes possible. Then, by continuously performing the single bonus (SB), the high probability state of both the single bonus (SB) and the challenge time (CT) is maintained. On the other hand, in the challenge time (CT), the single challenge time (SCT) is performed a plurality of times, and the high probability state of the single bonus (SB) is maintained during this time. Therefore, once the single bonus (SB) is won, the game can be advanced while the single bonus (SB) and the challenge time (CT) are alternately repeated.

Then, by setting the drawing probability of the big bonus (BB) or the regular bonus (RB) in the single bonus (SB) higher than the drawing probability of the big bonus (BB) or the regular bonus (RB) in the normal gaming state, A high probability state of bonus (BB) or regular bonus (RB) can be realized.
A specific example of such game characteristics will be described in detail later in (Type e) of [Best Mode for Carrying Out the Invention].

As described above, according to the present invention, it is possible to realize a high probability state of the bonus game by changing the drawing probability of each gaming state according to the number of bets on the game medium.
Specific games can include single bonus (SB), big bonus (BB), regular bonus (RB), single challenge time (SCT), challenge time (CT), etc. It is possible to have a high probability that is not present.

  Further, a predetermined specific gaming state in which only a predetermined number of game media bets for which a bonus game lottery probability is determined to be high is accepted as a single bonus (SB), and a single bonus (SB) in the single bonus (SB) By determining the drawing probability of the big bonus (BB) or the like high, it is possible to continuously win the single bonus (SB), and during this time, the drawing probability of the big bonus (BB) or the like can be kept high. For this reason, the charm of a single bonus (SB) can be improved dramatically.

  Similarly, a predetermined specific gaming state is set as a single challenge time (SCT), and the single challenge time (SCT) and the big bonus (BB) during the single challenge time (SCT) are set to be high so that the lottery probability is continuously increased. In this way, it is possible to win a single challenge time (SCT), and during this time, it is possible to maintain a high probability of drawing a big bonus (BB). For this reason, the charm of single challenge time (SCT) can be improved dramatically.

Furthermore, when a transition is made from a normal gaming state to another gaming state, such as a single bonus (SB), the probability of drawing a specific gaming state such as a big bonus (BB) becomes very high. Can raise the sense of expectation.
In addition, since the number of game medium bets varies according to the game state, the player can easily grasp the current game state.

  The first specific gaming state is a single bonus (SB), the second specific gaming state is a single challenge time (SCT), the third specific gaming state is a big bonus (BB), etc. By increasing the drawing probability of each of the first, second, and third specific gaming states in the game, and further increasing the drawing probability of each of the first, second, and third specific gaming states in the second specific gaming state The single bonus (SB) and the single challenge time (SCT) can be alternately repeated with a high probability, and the game medium is acquired a plurality of times by the single bonus (SB) and the single challenge time (SCT). The game can be performed while greatly enhancing the expectation of winning such as a big bonus (BB).

Similarly, the first specific gaming state is a single bonus (SB), the second specific gaming state is a challenge time (CT), the third specific gaming state is a big bonus (BB), and the like. By increasing the drawing probability of each of the first, second and third specific gaming states in the game, and further increasing the drawing probability of each of the first specific gaming states in the second specific gaming state, a single bonus (SB) And the challenge time (CT) are repeated alternately with high probability, and it is possible to acquire a game medium by the single bonus (SB) and the challenge time (CT), and the big bonus (BB), etc. It is possible to play games while greatly raising the expectation of winning.
And by making these feasible, it is possible to provide a slot machine full of new charm that has never existed before.

When the insertion button 7 is pressed, a medal signal is output to the control unit 10 (see FIG. 3), and the same number of medals are inserted from the stored medals stored in the RAM 12 into the game. Become. When a stored medal is inserted, the number of stored medals in the memory is subtracted by the number of inserted medals, and the numerical value displayed on the credit display unit 2b is also decreased by the number of inserted medals.

A gaming medal payout opening 8 and a speaker 9 are provided at the bottom of the slot machine 1.
In the game medal payout port 8, when the reels 21 stopped by pressing the stop button 5 are in a predetermined winning arrangement, a number of winning medals according to the winning arrangement discharged from the hopper device 30 in the housing is paid out. It is supposed to be. The number of medals paid out is displayed on the payout display part 2d constituting the state display part below the display window 3 of the reel.

The speaker 9 generates various sounds such as a melody sound and a message sound to the player. For example, when the control unit 10 performs an internal lottery and hits a predetermined jackpot or small role In addition, when winning symbols are arranged and a big win or a small role is won, a predetermined production sound, a sound for notifying the internal winning, or the like is generated.
The sound generated from the speaker 9 is generated and output to the sound circuit 17 provided in the control unit 10 (see FIG. 3).

FIG. 2 shows an outline inside the housing of the slot machine 1.
As shown in the figure, a drum unit 20 that rotates and stops the three reels 21a to 21c, a hopper device 30 that pays out medals, and other machines and devices are provided inside the casing of the slot machine 1. It has been.
The drum unit 20 rotatably holds the three reels 21a, 21b, and 21c and the three reels 21a to 21c, and rotates the stepping motors 23a to 23c corresponding to the reels 21a to 21c. A motor drive circuit 22 that controls the start of rotation of 21c, constant speed rotation and stop, and a rotation position detection unit that detects a stop position of each of the stopped reels 21a to 21c and outputs a position signal to the control unit 10 24 (see FIG. 3).

As in the existing slot machine, the reel 21 is composed of a cylindrical portion having a plurality of (usually 21) patterns and characters such as characters on the outer periphery, and is rotated in the vertical direction (vertical direction in the drawing). A reel (left) 21a, a reel (middle) 21b, and a reel (right) 21c are arranged in a row in the horizontal direction (left-right direction in the drawing) (see FIG. 2).
The symbols provided on each of the reels 21a to 21c are arranged at equal intervals for each reel. For example, characters such as “cherry”, “BAR”, and “replay”, a symbol indicating a slot machine character, fruit, etc. Are displayed in a predetermined order, and usually 21 symbols are displayed on each reel.
The symbols on the reels 21a to 21c are stopped in a predetermined combination along the winning line of the display window 3 described above by pressing the corresponding stop buttons 5a to 5c, and winning is determined. The

The three reels 21 a to 21 c are driven and stopped by the controller 10, the motor drive circuit 22 of the drum unit 20, and the rotation position detector 24.
In the drum unit 20, the three reels 21a to 21c are rotatably held by the corresponding three stepping motors 23a to 23c, respectively, and the start lever 4 and the stop buttons 5a to 5c are pressed to operate the motor drive circuit. 22 inputs a pulse (drive) signal from the control unit 10 to drive the stepping motors 23a to 23c (see FIG. 3), and controls the rotation start, constant speed rotation and stop of the corresponding reels 21a to 21c. Is called.

Then, the stop position of the reel 21 is controlled according to the result of the internal lottery performed by the control unit 10, regardless of the timing at which the player presses the stop button 5, that is, the pressing timing of each of the stop buttons 5 a to 5 c. Even if there is a deviation, the reels 21 are controlled to stop so that the symbols of the corresponding reels 21a to 21c are in a specific arrangement within a certain range (usually within the range of four symbols).
As a result, the control unit 10 performs an internal drawing in response to the start signal from the start lever 4, and the drum unit 20 is controlled by the control signal from the control unit 10, so that the stop button 5 is pressed. Instead, each reel 21a, 21b, 21c is stopped at a stop position corresponding to the result of the internal lottery within a certain range.

The hopper device 30 is a medal payout device disposed below the drum unit 20 in the housing. The hopper device 30 stores the payout medal, and drives the hopper 31 to discharge a predetermined number of medals. A hopper drive circuit 32 and a medal detection unit 33 that detects the number of discharged medals and outputs a payout number signal to the control unit 10 are provided (see FIG. 3).
The medals discharged from the hopper device 30 are paid out from the game medal payout port 8 of the front door 1a to the front surface of the slot machine and provided to the player.

Below the display window 3 of the front panel 2, an internal winning notification unit 2a, a credit display unit 2b, a status display unit 2c, and a payout display unit 2d are provided.
As a result of the internal lottery in the control unit 10 of the slot machine 1, the internal winning notification unit 2a is a lamp that lights or blinks when a predetermined big win is won, and a translucent display unit that translucently displays a pattern or the like by the light of the lamp And have.

Each of the credit display unit 2b, the status display unit 2c, and the payout display unit 2d includes a 7-segment LED and the like, and a predetermined numerical value is displayed.
That is, the credit display unit 2b displays the number of stored medals, the state display unit 2c displays the total number of paid-out medals and the number of digested games in the specific gaming state, and the payout display unit 2d displays the payout at the time of each payout. The number is displayed.
The display units of the internal hit notification unit 2a, the credit display unit 2b, the status display unit 2c, and the payout display unit 2d are driven and controlled by the display drive circuit 16 provided in the control unit 10 (FIG. 3). reference).

[Control means]
Next, with reference to FIG. 3, the control part 10 which controls the slot machine which concerns on this embodiment which consists of the above structures is demonstrated. FIG. 3 is a block diagram showing an outline of the control means of the slot machine and its peripheral configuration according to the present embodiment.
As shown in the figure, the control unit 10 of the present embodiment is a control means for controlling each part of the above-described slot machine 1, and has a microcomputer having an IC, a memory, various circuit boards, and the like. Has been.
Specifically, the control unit 10 includes a CPU 11, a RAM 12 and a ROM 13 serving as storage means, a clock generation circuit 14 that generates a reference clock, a random number generation circuit 15 that generates a random number for internal lottery, and the display units 2a to 2d. The display unit drive circuit 16 for driving the sound, the sound circuit 17 for generating sound through the speaker 9, the display unit drive circuit 18 for driving the display unit L for production, and the like.

  First, the control unit 10 inputs a medal signal from the medal selector 6a and a medal signal from the insertion button 7 (7a, 7b), and the number of medals inserted from the medal insertion slot 6 and the insertion button 7 are pressed. While confirming the number of inserted medals bet, the number of stored medals stored in the RAM 12 is decreased based on the medal signal from the insertion button 7. Thereby, the number of medals used (betting) for each game is determined.

Further, the control unit 10 inputs a start signal from the start lever 4 and a stop signal from the stop buttons 5a to 5c, thereby outputting a pulse (driving) signal serving as a control signal for the reel 21 to the drum unit 20, 21a-21c is rotated and stopped. Thus, in the drum unit 20, the reels 21a to 21c are rotated by the start signal, and the corresponding reels 21a to 21c are stopped by the stop signal input by pressing the stop buttons 5a to 5c.
Further, the control unit 10 recognizes the stop symbols of the reels 21a to 21c based on the marker signal input from the drum unit 20, and determines whether or not the stop symbols are in a predetermined winning arrangement. As a result, when the predetermined winning arrangement is selected, the medal payout process according to the type of winning is performed.

And the control part 10 which performs the above game control performs an internal lottery for every game, and controls the game according to the result of the internal lottery.
The internal lottery is a lottery process performed for each game, and is executed by a random number generation circuit 15 including a counter IC or the like and a lottery table preset and stored in the ROM 13, and the extracted random number is stored in any area of the lottery table. The contents indicated by the area to which the user belongs are determined and won as a lottery result.
Specifically, the random number generation circuit 15 generates a random number within a predetermined random width range (for example, 1 to 16384). The lottery table is a data table stored in the ROM 13, and predetermined winning contents are assigned corresponding to a range (1 to 16384, etc.) that a random value can take.

The winning contents set in the lottery table include jackpots (BB, RB, etc.), small roles, replays, loses, etc., and the winning contents are assigned to the lottery table corresponding to the range of the random number width. 1 to 55: jackpot, 55 to 1055: small role, 1056 to 16384: lost, etc., so that each content has a predetermined winning probability.
Then, at the moment when the start lever 4 is pressed, one random number is extracted from the random number generation circuit 15, and the extracted random number is compared with the value of the lottery table, so that the winning content to which the random number belongs is obtained as the lottery result. In accordance with the winning content, the stop position of the reel 21 is controlled. When a winning content is won, regardless of the timing at which the player presses the stop button 5, the symbols attached to each reel 21 within a certain range. Is controlled to be arranged in accordance with the winning content.

By the way, the above-described lottery table is one in which each winning content (each gaming state) is assigned within a range that the random number value can take. That is, the lottery table is a correspondence table between each random number value and the gaming state. And the lottery probability of each game state can be calculated | required from the lottery table. That is, the lottery probability of a certain game state (for example, big bonus (BB)) is calculated by changing the number of random numbers (for example, 55) to which the game state (big bonus (BB)) is assigned (for example, the number of all random numbers (for example, 16384 pieces) (here, about 1/300). If the lottery probability of each gaming state is calculated by such calculation, and these are combined, a lottery probability table as shown in FIG. 4 or FIG. 11 is obtained.
In the present embodiment, the lottery table and the lottery probability table are collectively referred to as an “internal lottery table”.

And the control part 10 performs an internal lottery based on the lottery probability defined in the internal lottery table (lottery probability table), and depending on the result of the winning, each game is in a specific gaming state or a normal gaming state. Control to do either.
Here, in the lottery probability table, the lottery probability of a specific gaming state in a predetermined number of gaming medium bets is set higher than the lottery probability of a specific gaming state in other gaming medium betting numbers, and this lottery probability is set to a predetermined value. The number of game media bets is determined to be accepted only in a predetermined specific game state.

In the control unit 10, internal lottery is performed in accordance with the contents determined by the lottery probability table. That is, control is performed so that a predetermined number of game medium bets that have a high lottery probability determined in the lottery probability table can be accepted only in a predetermined specific gaming state.
Here, “predetermined number of game media bets”, “number of other game media bets”, “specific game state”, “predetermined specific game state”, “lottery probability”, etc. can be arbitrarily determined. Due to game characteristics, rule restrictions, and the like, (type a) to (type e) listed in the following [specific examples of internal drawing] are main examples.
Specific examples of these internal lotteries will be described in detail below in [Specific examples of internal lottery].

[Specific examples of internal drawing]
Next, a specific example of the internal lottery performed by the control unit of the slot machine of this embodiment will be described with reference to FIGS.
FIGS. 4A to 4E are diagrams showing specific examples of lottery probability tables respectively used for the internal lottery types ((type a) to (type e)) in the slot machine of the present embodiment. .

  Moreover, the lottery probability tables shown in FIGS. 4A to 4E are merely examples. Therefore, as long as the high probability state of the bonus game is realized by changing the lottery probability of the game state according to the number of bets on the game medium, the game state and the lottery probability can be arbitrarily set in the lottery probability table. It goes without saying that it can be determined.

(Type a)
In this type, in the internal lottery table, the single bonus (SB) draw probability at a predetermined game medium bet number “1” is greater than the single bonus (SB) draw probability at another game medium bet number “3”. The lottery probability of the big bonus (BB) and the regular bonus (RB) at a predetermined game medium bet number “1” is set as the big bonus (BB) and the regular bonus ( RB) is determined to be higher than the lottery probability, and a predetermined game medium bet number “1” that increases the lottery probability is set as a single bonus (as long as the probability of those big bonuses (BB) and regular bonuses (RB) is increased). When accepting only in (SB) (however, the big bonus (B ) And lottery probability of regular bonus (RB) show a specific example of a case of a 0).

  As shown in FIG. 4A, the slot machine 1 of this type can win a small combination, replay (replay), and single bonus (SB) during a normal game. In addition, in the single bonus (SB), it is possible to win a small role, replay (replay), big bonus (BB), regular bonus (RB), and single bonus (SB).

In this type, the number of game medium bets (the number of bets) and the internal lottery probability are determined as shown in FIG.
That is, regarding the number of game media bets, the number of game media bets for the normal game and the big bonus (BB) is set to three, and the number of game media bets for the regular bonus (RB) and the single bonus (SB) is set to one. Yes.
On the other hand, with regard to the drawing probability, the drawing probability of the single bonus (SB) in the normal game is 1/100, the drawing probability of the big bonus (BB) in the single bonus (SB) is 1/5, and the regular bonus in the single bonus (SB) The (RB) drawing probability is set to 1/16, and the single bonus (SB) drawing probability for the single bonus (SB) is set to 1/2.

Here, looking at the number of gaming medium bets that can be accepted in normal games and the number of gaming medium bets that can be accepted with a single bonus (SB) “1”, the single bonus in the number of gaming medium bets “1”. The drawing probability (1/2) of (SB) is higher than the drawing probability (1/100) of the single bonus (SB) in the game medium betting number “3”. Also, the big bonus (BB) draw probability (1/5) at the game medium bet number “1” is higher than the big bonus (BB) draw probability (considered as 0) at the game medium bet number “3”. ing. Furthermore, the regular bonus (RB) draw probability (1/16) at the game medium bet number “1” is higher than the regular bonus (RB) draw probability (considered as 0) at the game medium bet number “3”. ing.
As long as the probability of drawing a big bonus (BB) or regular bonus (RB) increases, the game medium bet number “1” can be accepted only with a single bonus (SB). It is not accepted. For this reason, in the single bonus (SB), the probability of drawing the big bonus (BB) and the regular bonus (RB) can be made extremely high.
In this type, not only the single bonus (SB) but also the regular bonus (RB), the number of game media bets is “1”. However, in the regular bonus (RB), the big bonus (BB) and the regular bonus (RB) are not drawn. For this reason, the regular bonus (RB) is not included in the range of “as long as the drawing probability of the big bonus (BB) or the regular bonus (RB) is high”.

Next, the flow of the game in this type of slot machine 1 will be described with reference to FIG.
The player first plays a game in the normal game state (normal game) in expectation of winning a single bonus (SB). Here, the drawing probability of the single bonus (SB) is 1/100. This is, for example, a probability that the winning is easier than the drawing probability 1/800 of the big bonus (BB) shown in FIG.
If the single bonus (SB) is won or won, the game is played in the hope of winning the next big bonus (BB) or regular bonus (RB).
During the single bonus (SB), the drawing probability of the big bonus (BB) is 1/5 and the regular bonus (RB) is 1/16, both of which are much easier to win. Thus, in this type of slot machine 1, a high probability of the bonus game can be realized.

  Further, during the single bonus (SB), the drawing probability of the single bonus (SB) is ½. This means that the possibility of winning / winning the single bonus (SB) during the single bonus (SB) is very high. For this reason, a single bonus (SB) can be performed many times continuously. Moreover, during the single bonus (SB), the probability of drawing a big bonus (BB) or a regular bonus (RB) is dramatically increased. From this, as long as the single bonus (SB) continues, the state where the probability of drawing such as the big bonus (BB) is high continues. Therefore, the player can continue playing the game while greatly increasing the expectation of winning such as a big bonus (BB) by continuously performing the single bonus (SB). Therefore, the slot machine 1 of this type can provide the slot machine 1 with completely new gameplay that has never been achieved.

(Type b)
This type, like type a, in the internal lottery table, the single bonus (SB) draw probability at a predetermined game medium bet number “1” is set as the single bonus (SB) at the other game medium bet number “3”. And the probability of drawing the big bonus (BB) and regular bonus (RB) at a predetermined game medium bet number “1” is set to the big bonus (BB) at the other game medium bet number “3”. ) And regular bonus (RB) are set higher than the drawing probability, and a predetermined number of game media bets “1” that increases the drawing probability is increased (the drawing probability of those big bonus (BB) and regular bonus (RB) is high. A specific example in the case of accepting only in the single bonus (SB) is shown.
However, as a difference from type a, the lottery probability of the big bonus (BB) and the regular bonus (RB) in the normal gaming state is other than zero.

  As shown in FIG. 4 (b), this type of slot machine 1 has a small role, a replay (replay), a big bonus (BB), a regular bonus (RB), and a single bonus (SB) during a normal game. It is possible to win. Similarly, during a single bonus (SB), a small bonus, replay (replay), big bonus (BB), regular bonus (RB), and single bonus (SB) can be won.

In this type, the number of game medium bets (the number of bets) and the internal lottery probability are determined as shown in FIG. 4B.
The number of game media bets is the same as type a.
On the other hand, with regard to the lottery probability, the lottery probability of the big bonus (BB) in the normal game and the lottery probability of the regular bonus (RB) in the normal game are both 1/800, and the lottery probability of the single bonus (SB) in the normal game is 1. / 150, Single Bonus (SB) Single Bonus (SB), Single Bonus (SB) Single Bonus (SB) (1/8), Single Bonus (SB) Regular Bonus (RB) Drawing Probability The probability of lottery for SB) is set to 1/2.

Here, looking at the number of gaming medium bets that can be accepted in normal games and the number of gaming medium bets that can be accepted with a single bonus (SB) “1”, the single bonus in the number of gaming medium bets “1”. The drawing probability (1/2) of (SB) is higher than the drawing probability (1/150) of the single bonus (SB) in the game medium betting number “3”. In addition, the big bonus (BB) drawing probability (1/8) at the game medium bet number “1” is higher than the big bonus (BB) drawing probability (1/800) at the game medium bet number “3”. ing. Further, the probability (1/8) of the regular bonus (RB) drawing at the game medium bet number “1” is higher than the probability (1/800) of the regular bonus (RB) at the game medium bet number “3”. ing.
As long as the probability of drawing a big bonus (BB) or regular bonus (RB) increases, the game medium bet number “1” can be accepted only with a single bonus (SB). It is not accepted. For this reason, in the single bonus (SB), the probability of drawing the big bonus (BB) and the regular bonus (RB) can be made extremely high.
In this type, not only the single bonus (SB) but also the regular bonus (RB), the number of game media bets is “1”. However, in the regular bonus (RB), the big bonus (BB) and the regular bonus (RB) are not drawn. For this reason, the regular bonus (RB) is not included in the range of “as long as the drawing probability of the big bonus (BB) or the regular bonus (RB) is high”.

Next, the flow of the game in this type of slot machine 1 will be described with reference to FIG.
The player can expect a big bonus (BB) or regular bonus (RB) to be won in the normal game, but since the probability of lottery is low, the single bonus (SB) is first used in the normal game here. Playing games in anticipation of winning. Since the drawing probability of the single bonus (SB) is 1/150, it is easier to win than the drawing probability of 1/800 such as the big bonus (BB).

If the single bonus (SB) is won or won, the game is played in the hope of winning the next big bonus (BB) or regular bonus (RB).
During the single bonus (SB), the drawing probability of both the big bonus (BB) and the regular bonus (RB) is 1/8. It has become much easier to win. Thus, in this type of slot machine 1, a high probability of the bonus game can be realized.

  Further, during the single bonus (SB), the drawing probability of the single bonus (SB) is ½. For this reason, a single bonus (SB) can be performed many times continuously. From this, as long as the single bonus (SB) continues, the state where the probability of drawing such as the big bonus (BB) is high continues. Therefore, the slot machine 1 of this type can provide the slot machine 1 with completely new gameplay that has never been achieved.

(Type c)
This type is similar to type a and type b, in the internal lottery table, the single bonus (SB) lottery probability at a predetermined game medium bet number “1” is set as the single bonus at other game medium bet numbers “3”. (SB) is determined to be higher than the lottery probability, and the lottery probability of the big bonus (BB) and the regular bonus (RB) at the predetermined game medium bet number “1” is set to the big at other game medium bet numbers “3”. A predetermined game medium bet number “1” that increases the drawing probability of the bonus (BB) and the regular bonus (RB) and increases the drawing probability (the big bonus (BB) and the regular bonus (RB) drawing) A specific example of accepting only a single bonus (SB) as long as the probability is high A.

However, the slot machine 1 of this type is different from the slot machine 1 of type a or type b in that a single challenge time (SCT) or a challenge time (CT) is newly installed.
And during single challenge time (SCT), small role, replay (replay), big bonus (BB), regular bonus (RB), challenge time (CT), single challenge time (SCT), single bonus (SB) It is possible to win. In addition, during the challenge time (CT), small bonuses, regular bonus (RB), and single bonus (SB) can be won.

  For this reason, this type is different from Type a and Type b in that, in the internal drawing table, a big bonus (BB), regular bonus (RB), challenge time (CT) for a predetermined number of game media bets “2” ), Single Challenge Time (SCT), Single Bonus (SB) lottery probability, Big Bonus (BB), Regular Bonus (RB), Challenge Time (CT), Single Challenge in other game media bet number “3” Specific case where the predetermined number of game media bets “2”, which is set higher than the lottery probabilities of time (SCT) and single bonus (SB), and can be accepted only during the single challenge time (SCT) An example is given.

  Furthermore, this type is different from Type a and Type b in that the lottery probabilities of challenge time (CT) and single challenge time (SCT) at a predetermined number of game media bets “1” are set in the internal lottery table. The predetermined game medium bet number “1”, which is set higher than the draw probability of the challenge time (CT) and the single challenge time (SCT) in the other game medium bet number “3” and becomes high A specific example in the case of accepting only the single bonus (SB) (as long as the drawing probability of the big bonus (BB) and the regular bonus (RB) becomes high) is shown.

In this type, the number of game medium bets (the number of bets) and the internal lottery probability are determined as shown in FIG.
With regard to the number of game media bets, the number of game media bets for normal game, big bonus (BB), challenge time (CT), 3 game media bets for single challenge time (SCT), regular bonus ( The number of game media bets for RB) and single bonus (SB) is defined as one.

On the other hand, with regard to the lottery probability, during normal games, the lottery probability of big bonus (BB), regular bonus (RB), challenge time (CT) is 1/800, single challenge time (SCT) and single bonus (SB) The lottery probability is set to 1/150.
Further, during the challenge time (CT), the regular bonus (RB) drawing probability is set to 1/800, and the single bonus (SB) drawing probability is set to 1/150.

Also, during the single challenge time (SCT), the probability of drawing a big bonus (BB) is 1/20, the probability of drawing a regular bonus (RB) is 1/50, the probability of drawing a challenge time (CT) is 1/12, The drawing probability of the single challenge time (SCT) is set to 1/2, and the drawing probability of the single bonus (SB) is set to 1/10.
In addition, during the single bonus (SB), the drawing probability of the big bonus (BB) is 1/12, the drawing probability of the regular bonus (RB) is 1/50, and the drawing probability of the challenge time (CT) is 1/20. The challenge time (SCT) drawing probability is set to 1/10, and the single bonus (SB) drawing probability is set to 1/2.

Here, looking at the game medium bet number “3” that can be accepted in the normal game and the game medium bet number “1” that can be accepted by the single bonus (SB), the big bonus at the game medium bet number “1” is as follows. (BB) drawing probability (1/12), regular bonus (RB) drawing probability (1/50), challenge time (CT) drawing probability (1/20), single challenge time (CT) drawing probability ( 1/10) and Single Bonus (SB) draw probability (1/2) are the Big Bonus (BB) draw probability (1/800) and Regular Bonus (RB) draws, respectively, when the number of betting media is 3 Probability (1/800), Challenge time (CT) drawing probability (1/800), Single challenge time (CT) drawing probability (1/150), It is higher than the lottery probability of bridging Le bonus (SB) (1/150).
As long as the probability of drawing a big bonus (BB) or regular bonus (RB) increases, the game medium bet number “1” can be accepted only with a single bonus (SB). It is not accepted. Therefore, in the single bonus (SB), the probability of drawing each of the big bonus (BB), regular bonus (RB), challenge time (CT), single challenge time (CT), and single bonus (SB) is very high. It can be.
In this type, not only the single bonus (SB) but also the regular bonus (RB), the number of game media bets is “1”. However, in the regular bonus (RB), the big bonus (BB) and the regular bonus (RB) are not drawn. For this reason, the regular bonus (RB) is not included in the range of “as long as the drawing probability of the big bonus (BB) or the regular bonus (RB) is high”.

Furthermore, looking at the game media bet number “3” that can be accepted in the normal game and the game media bet number “2” that can be accepted in the single challenge time (SCT), the big bonus in the game media bet number “2” (BB) drawing probability (1/20), regular bonus (RB) drawing probability (1/50), challenge time (CT) drawing probability (1/12), single challenge time (CT) drawing probability ( 1/2), Single Bonus (SB) drawing probability (1/10) is Big Bonus (BB) drawing probability (1/800) and Regular Bonus (RB) drawing for the game media bet number “3”, respectively. Probability (1/800), challenge time (CT) drawing probability (1/800), single challenge time (CT) drawing probability (1/800) 50), it is higher than the lottery probability of a single bonus (SB) (1/150).
The game medium bet number “2” can be accepted only in the single challenge time (SCT), and cannot be accepted in other game states. For this reason, during the single challenge time (SCT), each lot probability of the big bonus (BB), regular bonus (RB), challenge time (CT), single challenge time (CT), and single bonus (SB) is very high. Can be.

Next, the flow of the game in this type of slot machine 1 will be described with reference to FIG.
Players can also expect to win big bonuses (BB), regular bonuses (RB), and challenge times (CT) in regular games, but these are very low in the lottery probability. Then, a game is played in expectation of winning a single challenge time (SCT) or a single bonus (SB).
The drawing probability of the single challenge time (SCT) and the single bonus (SB) are both 1/150. These are numbers that are easier to win compared to a lottery probability 1/800 such as a big bonus (BB).

If a single challenge time (SCT) or a single bonus (SB) is won or won, a game is played in the hope of winning a big bonus (BB) or regular bonus (RB).
For example, during the single bonus (SB), the probability of drawing the big bonus (BB) is 1/12 and the regular bonus (RB) is 1/50, both of which are much easier to win (single challenge time ( The same applies during SCT).
Here, it is possible to play a game with the expectation of winning the challenge time (CT), and to play the game with the expectation of winning a regular bonus (RB) during the challenge time (CT). However, since the probability of drawing the regular bonus (RB) during the challenge time (CT) is 1/800, winning the regular bonus (RB) during the single challenge time (SCT) or during the single bonus (SB) It is easier to play games with the expectation of

Further, during the single bonus (SB), the drawing probability of the single bonus (SB) is ½. For this reason, a single bonus (SB) can be performed many times in succession, and a state in which a lottery probability such as a big bonus (BB) is high can be continued.
In addition, the single challenge time (SCT) during the single challenge time (SCT) has a high probability of ½, so the single challenge time (SCT) is repeated many times and the big bonus (BB ) Etc. can be kept in a state with a high probability of lottery.

Further, as a feature of this type, a single bonus (SB) and a single challenge time (SCT) are repeatedly performed alternately with high probability.
As shown in FIG. 4C, the drawing probability of the single bonus (SB) and the single challenge time (SCT) in the single bonus (SB) is the same as the single bonus (SB) and the single challenge time (SCT) in the normal gaming state. It is set higher than the lottery probability. Also, the single bonus (SB) and single challenge time (SCT) drawing probabilities in the single challenge time (SCT) are set higher than the single bonus (SB) and single challenge time (SCT) drawing probabilities in the normal gaming state. ing.

For this reason, when a single bonus (SB) is won, for example, in the normal gaming state, the single bonus (SB) and single challenge time (SCT) are drawn with a high probability in the next single bonus (SB). If you win or win a single challenge time (SCT), the next single challenge time (SCT) will be held. In the single challenge time (SCT), the single bonus (SB) and the single challenge time (SCT) are drawn with a high probability. If the single bonus (SB) is won and won, A single bonus (SB) is performed.
Thus, once winning the single bonus (SB) or single challenge time (SCT), both the single bonus (SB) and the single challenge time (SCT) are in a high probability state, and thereafter, the single bonus (SB) The game can be advanced while repeating SB) and single challenge time (SCT).

Moreover, in the single bonus (SB), since the probability of drawing the single bonus (SB) is high, the single bonus (SB) can be won or won during the single bonus (SB), and the single bonus (SB) can be continued. It becomes possible. Then, by continuously performing the single bonus (SB), the high probability state of both the single bonus (SB) and the single challenge time (SCT) is maintained. On the other hand, even in the single challenge time (SCT), the single challenge time (SCT) can be continuously performed because the probability of drawing the single challenge time (SCT) is high. The single challenge time (SCT) is continuously performed, so that a high probability state of the single challenge time (SCT) and the single bonus (SB) is maintained.
Therefore, once a single bonus (SB) or single challenge time (SCT) is won, the game can be advanced while the single bonus (SB) and the single challenge time (SCT) are alternately repeated.

  Furthermore, the drawing probability of the big bonus (BB) or the regular bonus (RB) in the single bonus (SB) or the single challenge time (SCT) is larger than the drawing probability of the big bonus (BB) or the regular bonus (RB) in the normal gaming state. By setting a higher value, a high probability state of a big bonus game (BB) or a regular bonus (RB) can be realized.

(Type d)
This type of slot machine 1 is different from the type a slot machine 1 in that it has two types of big bonuses (BB1, BB2) instead of the regular bonus (RB). To do.
The first big bonus (BB1) has the same game content as the big bonus (BB) in the type a slot machine 1.
The second big bonus (BB2) is a game in which a bonus game called replay time (RT) is continued after the end of the big bonus (BB1).

  The replay time (RT) is a gaming state in which the probability that the re-playing symbols are aligned with the winning line is very high. In this replay time (RT), it is possible to expect winning / winning of the next big bonus (BB) while suppressing a decrease in game media (medals). Moreover, it is possible to expect a winning / winning of a single bonus (SB) for a certain number of games with a high probability.

  In this type, in the internal lottery table, the single bonus (SB) drawing probability at a predetermined game medium bet number “1” is set as the single bonus (SB) drawing probability at another game medium bet number “3”. And the probability of drawing the first and second big bonuses (BB1, BB2) at the predetermined game medium bet number “1” is set to the first and second at the other game medium bet number “3”. A specific example is shown in which a predetermined game medium bet number “1” that is set higher than the lottery probability of the big bonus (BB1, BB2) and can be accepted only in the single bonus (SB) is increased. Is.

In this type, the number of game medium bets (the number of bets) and the internal lottery probability are determined as shown in FIG.
With regard to the number of game media bets, three game media bets for the normal game, the first big bonus (BB1) and the second big bonus (BB2), and the number of game media bets for the single bonus (SB) are 1. It is defined as a sheet.

On the other hand, with regard to the lottery probability, during the normal game, the lottery probability of the first big bonus (BB1) is 1/300, the lottery probability of the second big bonus (BB2) is 1/10000, and the single bonus (SB) The lottery probability is set to 1/300.
Also, during the single bonus (SB), the first big bonus (BB1) drawing probability is 1/16, the second big bonus (BB2) drawing probability is 1/5, and the single bonus (SB) drawing probability. Is defined as 1/2.

Here, looking at the number of gaming medium bets that can be accepted in normal games and the number of gaming medium bets that can be accepted with a single bonus (SB) “1”, the single bonus in the number of gaming medium bets “1”. The drawing probability (1/2) of (SB) is higher than the drawing probability (1/300) of the single bonus (SB) in the game medium betting number “3”. In addition, the drawing probability (1/16) of the first big bonus (BB1) at the number of gaming medium bets “1” is equal to the drawing probability (1/16) of the first big bonus (BB1) at the number of gaming media bets “3”. 300). Further, the drawing probability (1/5) of the second big bonus (BB2) at the number of gaming media bets “1” is equal to the drawing probability (1 / of the second big bonus (BB2) at the number of gaming media bets “3”. 10,000).
The game medium bet number “1” can be accepted only with a single bonus (SB), and cannot be accepted in other game states. For this reason, the drawing probability of the first and second big bonuses (BB1, BB2) can be made very high during the single bonus (SB).

Next, the flow of the game in this type of slot machine 1 will be described with reference to FIG.
There are a first big bonus (BB1), a second big bonus (BB2), and a single bonus (SB) as specific games that may be won in a normal game, but the second big bonus (BB2) is Since the lottery probability is 1/10000, it can be said that it is equal to not winning. However, the player wants to expect to win a second big bonus (BB2) that can be obtained in large quantities. Therefore, as a player, first, a game is played in the hope of winning a single bonus (SB). The drawing probability of a single bonus (SB) is 1/300.

If the single bonus (SB) is won or won, the game is played in the hope of winning the second big bonus (BB2).
During the single bonus (SB), the second big bonus (BB2) is 1/5, which is much easier to win.
Further, during the single bonus (SB), the drawing probability of the single bonus (SB) is ½. For this reason, a single bonus (SB) can be performed many times continuously. Thus, as long as the single bonus (SB) continues, the state in which the probability of drawing the second big bonus (BB2) is high continues.

  In the game flow described above, the single bonus (SB) is won / winned, and then the second big bonus (BB2) is won / winned. It is also possible to play a game so as to win a large amount of game media by winning and winning the first big bonus (BB1).

(Type e)
The slot machine 1 of this type is different from the slot machine 1 of type a in that a challenge time (CT) is mounted instead of a regular bonus (RB).
In this type, in the internal lottery table, the lottery probabilities of the big bonus (BB), challenge time (CT), and single bonus (SB) when the predetermined number of game media bets is “1” are set to other game media bets. Set higher than the probability of drawing big bonus (BB), challenge time (CT), and single bonus (SB) in “3”, and determine the probability of drawing single bonus (SB) in the number of game media bets “2”, etc. The game medium bet number “3” is set higher than the single bonus (SB) lottery probability, and a predetermined game medium bet number “1” that increases the lottery probability can be accepted only in the single bonus (SB). A specific example when the number of game media bets “2” can be accepted only during the challenge time (CT) A.

In this type, the number of game medium bets (the number of bets) and the internal lottery probability are determined as shown in FIG.
Regarding the number of game media bets, three game media bets for normal game and big bonus (BB), two game media bets for challenge time (CT), and single media (SB) game media bets The number is defined as one.

On the other hand, with regard to the lottery probability, during normal games, the lottery probability of the big bonus (BB) is set to 1/1000, the lottery probability of the challenge time (CT) is set to 1/200, and the lottery probability of the single bonus (SB) is set to 0. ing.
Further, during the challenge time (CT), the drawing probability of the single bonus (SB) is set to 1/16.
Furthermore, during the single bonus (SB), the big bonus (BB) draw probability is set to 1/5, the challenge time (CT) draw probability is set to 1/4, and the single bonus (SB) draw probability is set to 1/4. ing.

Here, looking at the game medium bet number “3” that can be accepted in the normal game and the game medium bet number “1” that can be accepted by the single bonus (SB), the big bonus at the game medium bet number “1” is as follows. (BB) lottery probability (1/5), challenge time (CT) lottery probability (1/4), single bonus (SB) lottery probability (1/4) at the game medium bet number “3”, respectively. It is higher than the drawing probability (1/1000) of the big bonus (BB), the drawing probability (1/200) of the challenge time (CT), and the drawing probability (0) of the single bonus (SB).
Also, when looking at the number of betting media bets “3” that can be accepted in normal games and the number of betting media bets “2” that can be accepted at challenge time (CT), a single bonus ( The drawing probability (1/16) of SB) is higher than the drawing probability (0) of the single bonus (SB) in the game medium betting number “3”.

  In addition, the game medium bet number “1” can be accepted only with a single bonus (SB), and cannot be accepted in other gaming states. Further, the game medium bet number “2” can be accepted only in the challenge time (CT), and cannot be accepted in other game states. For this reason, each lot probability of big bonus (BB), challenge time (CT) and single bonus (SB) in single bonus (SB) and single bonus (SB) lottery probability in challenge time (CT) are very high. Can be expensive.

Next, the flow of the game in this type of slot machine 1 will be described with reference to FIG.
The player can expect a big bonus (BB) win in a normal game, but since the probability of lottery is low, the player first plays a game in anticipation of a challenge time (CT) win. The challenge time (CT) lottery probability is 1/200. This is a number that is easier to win than the probability of drawing such as a big bonus (BB1). During normal games, the single bonus (SB) is not won.

When the challenge time (CT) is won or won, the game is played in the hope of winning a single bonus (SB). During the challenge time (CT), the drawing probability of the single bonus (SB) is 1/16, making it easier to win.
When a single bonus (SB) is won or won, a game is played in the hope of winning a big bonus (BB). During the single bonus (SB), the probability of drawing the big bonus (BB) is 1/5, which makes it easier to win.

  Further, during the single bonus (SB), the drawing probability of the single bonus (SB) is 1/4. For this reason, a single bonus (SB) can be performed many times continuously. Therefore, as long as the single bonus (SB) continues, the state where the probability of drawing the big bonus (BB) is high continues.

Further, as a feature of this type, a single bonus (SB) and a challenge time (CT) are repeatedly performed alternately with high probability.
As shown in FIG. 4E, the drawing probability of the single bonus (SB) and the challenge time (CT) in the single bonus (SB) is the drawing probability of the single bonus (SB) and the challenge time (CT) in the normal gaming state. Is set higher than. In addition, a single bonus (SB) drawing probability in the challenge time (CT) is set higher than a single bonus (SB) drawing probability in the normal gaming state.

For this reason, if, for example, a challenge time (CT) is won in the normal gaming state, a single bonus (SB) is drawn with a high probability in the challenge time (CT) performed after the next game, and the single bonus (SB) is not won here.・ If you win, you will be given a single bonus (SB). In this single bonus (SB), the single bonus (SB) and the challenge time (CT) are drawn with a high probability, and if the challenge time (CT) is won or won, then the challenge time (CT) ) Is performed.
Thus, once winning the challenge time (CT), the game can be advanced while repeating the single bonus (SB) and the challenge time (CT) thereafter.

Moreover, in the single bonus (SB), since the probability of drawing the single bonus (SB) is high, the single bonus (SB) can be won or won during the single bonus (SB), and the single bonus (SB) can be continued. It becomes possible. Then, by continuously performing the single bonus (SB), the high probability state of both the single bonus (SB) and the challenge time (CT) is maintained. On the other hand, in the challenge time (CT), a plurality of single challenge times (SCT) are played until a predetermined number of payouts (for example, several hundreds) are reached or until a predetermined condition is satisfied. The probability state is maintained.
Therefore, once winning the challenge time (CT), it is possible to advance the game while alternately repeating the single bonus (SB) and the challenge time (CT).

  Furthermore, since the probability of drawing the big bonus (BB) in the single bonus (SB) is set higher than the probability of drawing the big bonus (BB) in the normal gaming state, the big bonus game (BB) in the single bonus (SB) ) High probability state can be realized.

  The type e slot machine 1 in the present embodiment is configured not to be equipped with a regular bonus (RB), but the type e slot machine 1 may be configured to be equipped with a regular bonus (RB). it can. In this case, for example, the regular bonus (RB) drawing probability in the normal game is set to about 1/500, the regular bonus (RB) drawing probability in the single bonus (SB) is set to about 1/5, and the single bonus (SB) is set. A high probability of regular bonus (RB) can also be realized.

[Game operation]
Next, the gaming operation of the slot machine according to the embodiment as described above will be described with reference to FIG.
FIG. 10 is a flowchart showing an outline of the gaming operation of the slot machine according to the present embodiment.
First, the game is started when the player inserts a medal into the medal slot 6 (step 1001 in FIG. 10). The game started at this time is a normal game.
Here, the medals to be inserted are usually assigned to one bet, two bets, three bets corresponding to the pay line on the display window 3, and when four or more medals are inserted, four medals are inserted. The medals after the first are stored in the RAM 12 of the control unit 10 as stored medals. Therefore, the stored medal is used for the second and subsequent games by the insertion button 7.

After the medal is inserted, the start lever 4 is pressed (step 1002), the three reels 21 start rotating, and at the same time, the control unit 10 performs an internal lottery (step 1003).
Here, as a result of the internal lottery, when a predetermined jackpot (BB) is won, a predetermined internal winning notification is made via the internal winning notification 2a simultaneously with the start of the game or after the game ends. Can be done.

Thereafter, when the player presses the stop buttons 5a to 5c (step 1004), the reels 21a to 21c corresponding to the stop buttons 5a to 5c are controlled to stop (step 1005).
At this time, the reels 21a to 21c are controlled by the control unit 10 and the drum unit 20, and the symbols on the reels correspond to the winning contents of the internal lottery within a certain range regardless of the timing of pressing the stop button 5. Stop control is performed so as to obtain a predetermined arrangement.

When all the reels 21a to 21c are stopped (step 1005), processing corresponding to the stopped symbols is performed.
First, as a result of the internal lottery (step 1006), if the jackpot has not been won (No in step 1006), it is then determined whether or not the jackpot has been hit (step 1007), and this jackpot has not been hit. If so (Yes in Step 1007), the game medium corresponding to the winning arrangement is paid out (Step 1009) on the condition that the reel stop symbols are in a predetermined winning arrangement (Step 1008).
Thereafter, the continuation or end of the game is selected according to the player's judgment (step 1010).

On the other hand, as a result of the internal lottery (step 1003), when a big hit is made (Yes in step 1006), the flag is established, and if the stop symbol of the reel 21 is in a predetermined winning arrangement, a win is won ( In step 1011), the specific game state is entered and the specific game is played (step 1012).
If the stop symbol is not in the predetermined winning arrangement (No in Step 1011), the specific game is not started, and if it is playing a small role according to the stopped symbol arrangement (Yes in Step 1007), the reel On the condition that the stop symbol is a predetermined winning arrangement (step 1008), game media corresponding to the winning arrangement is paid out (step 1009).
Thereafter, the continuation or end of the game is selected according to the player's judgment (step 1010).

The configuration of the slot machine 1 according to the present embodiment described above is substantially the same as the configuration and functions of the existing slot machine except for the above-described parts, and the game method, the game system, and the like are also substantially the same. is there.
Therefore, detailed description of the same parts as those of the existing machine is omitted.

As described above, according to the slot machine according to the present embodiment, it is possible to realize a high probability state of the bonus game by changing the lottery probability of the game state according to the number of bets on the game medium.
Further, if the predetermined specific gaming state is a single bonus (SB) or single challenge time (SCT), the attractiveness of these specific gaming states can be dramatically improved.

In addition, when a transition is made from a normal game to a specific game state such as a single bonus (SB), the probability of drawing a game state such as a big bonus (BB) becomes very high. Expectation can be raised.
In addition, since the number of game medium bets varies according to the game state, the player can easily grasp the current game state.
And by making these possible, it is possible to provide a slot machine full of new appeal that never existed before.

The preferred embodiment of the slot machine of the present invention has been described above.
