Description

  The present invention relates to a gaming machine capable of determining a game section of a special game based on a transition lottery probability used for a transition lottery for determining whether or not to shift from a normal game to a special game.

  Conventionally, in a gaming machine such as a slot machine, a plurality of rotating reels capable of variably displaying a plurality of symbols, a start switch for starting a variation display of the symbols of the rotating reels by a player's operation, and a plurality of rotating reels, respectively. And a plurality of stop switches for individually stopping the change display of the symbols on the rotating reels by the player's operation after the start of the display of the change of the symbols on the plurality of rotating reels, and the progress and effect of the game And a control device for notifying the outside of various effects, and the control device has a role lottery means for performing a lottery for winning or losing a plurality of roles. The rotation of the rotating reel is stopped based on the result of the winning lottery and the stop operation of the stop switch, and it is determined whether or not the combination of symbols related to the winning winning combination is aligned on an effective line. , And so as to impart a predetermined benefit, depending on the result of the determination.

In addition, in conventional gaming machines, a normal game that is normally performed and a special game that is more likely to give a privilege than the normal game are provided as games. This special game is performed at a predetermined opportunity, and can be transferred according to the result of a lottery (hereinafter referred to as “transfer lottery”) whether or not to shift to a special game during a normal game. The number of games can be added by lottery or the like.
Here, as a conventional technique, there is one that can substantially increase the number of medals that can be acquired during a special game when a predetermined symbol is arranged during a special game such as a bonus (Patent Document 1).

JP 2009-118902 A

  In the conventional technology as described above, it is possible to know the number of acquired games that can be finally obtained during the special game after the special game is finished, based on the predetermined lottery result and game result during the special game. However, the player generally does not understand what the lottery probability of the transition to special games (the so-called transition lottery probability) was. The so-called “pull”, which is difficult to win the transition lottery of special games, and tends to be disadvantageous (bad) for the player rather than the frequency (timing) of the winning lottery estimated from the probability of the transition lottery. Who is in the “weak, weak” state or who wins the transition lottery of the special game earlier than the frequency (timing) of the transition lottery estimated from the transition lottery probability, and is advantageous to the player Whether it was the so-called “strong pulling, strong pulling” state, which was biased towards (the better one), or which of these was interesting to the player, but the player did not understand .

In view of the above problems, the present onset Ming, special play of the game segment results (e.g., length) from, it is possible to estimate the transition lottery probability used for migration lottery having transferred to the special game, transition lottery It is possible to judge whether the timing of winning the game is earlier or later than the timing calculated from the transition lottery probability (whether it is a strong or weak state), and an entertaining game can be implemented An object is to provide a gaming machine.
In addition, the present invention further reduces the period of entanglement even if a large amount of profits cannot be obtained at once, and the player's feeling that he wants to win the transition lottery at an early stage, It is an object of the present invention to provide a gaming machine capable of responding to a player's feeling that he wants to increase profits to the player.
The present invention further provides a tendency or relationship between the transition lottery probability due to continuation of the game and the initial value of the number of medals that can be acquired during the special game set at the start of the special game (initially obtainable number). It is possible to determine the transition lottery probability expected by the player himself, and whether the current state is a strong pulling state with a strong pull or a weak pulling weak state To provide a gaming machine that can generate a pleasure for a player to be able to make an answer such as whether or not the prediction has been made by comparing the prediction with the reality With the goal.

In addition, the present invention further reduces the period of entanglement even if the initial obtainable number is small, and the player's feeling that he wants to win the transition lottery at an early stage, An object of the present invention is to provide a gaming machine capable of responding to the player's feeling that the initial value (initial number of obtainable sheets) is desired to be increased.
The present invention further allows the player to easily generate a high-preferential state and a low-preferential state by setting a transfer lottery probability, and a game with a rough wave of profit for the player. An object is to provide a gaming machine that can be easily formed.
The present invention can further change the result (for example, length (long or short)) of the game section when the game is shifted to the special game at a predetermined opportunity during the normal game, and can be obtained during the special game. It is an object of the present invention to provide a gaming machine that can change the profit of the game and can make the feeling of expectation and gameability rich.

The gaming machine 10 according to the present invention is characterized by the following points. That is, in the gaming machine 10 having a normal game that is normally played and a special game that is more advantageous to the player than the normal game as a game, a lottery of whether or not to shift from the normal game to the special game (hereinafter referred to as the game) , “Transition lottery”.) Transition condition determining means 190 for determining a lottery probability (hereinafter referred to as “Transition lottery probability”) to be used for the transition lottery, and using the transition lottery probability during the normal game Transition lottery means 330 for performing the game, and a game section of the special game corresponding to the transition lottery probability is set in advance, and the special game is determined based on the transition lottery probability determined by the transition condition determining means 190. and a special game segment determining means 200 for determining a game section, with the length of the game section of one special game for one transition lottery probability is compatible, the transition lottery probability, special Characterized in that it is estimated to be able to set the length of the game segment of the technique.
Here, “the game section of the special game corresponding to the transition lottery probability is set in advance” means that the transition lottery probability and the result (for example, length) of the game section of the special game are in advance. The case where it is determined that there is a certain relevance by an arithmetic expression, the case where both are determined by a table (table), and the like are included.

In the present invention, the game section of the special game is determined based on the transfer lottery probability in the transfer lottery for shifting to the special game. In other words, there is a correspondence (association) between the ease of transitioning to a special game (difficulty) and the result (for example, length) of the game section of the special game based on the transition lottery probability.
Since there is a correspondence between the transition lottery probability and the result (for example, length) of the special game, the result (for example, length) of the special game at the start or end of the special game. When it becomes clear, the transfer lottery probability used for the transfer lottery that has shifted to the special game can be estimated from the result.

A player who has been able to estimate the transfer lottery probability will move to the next (current or future) normal game after the end of the special game and the timing of winning the transfer lottery in the previous (previous) normal game It can be determined whether or not the timing for winning the lottery is earlier or later than the timing calculated from the transfer lottery probability.
In other words, the player who has been able to estimate the transition lottery probability shifts to the normal game from the end of the special game such as the transition lottery probability set in the gaming machine determined by the game section and the previous time or this time. By comparing the result of the transfer lottery probability calculated by the number of games until winning the next special game, the result of the transfer lottery such as the previous time or this time is disadvantageous for the player (the worse one) ), So-called “weak pulling, weak pulling” state, or so-called “strong pulling, strong pulling” state, which is biased toward the player's advantage (the better one) It can be judged whether it was.

  As a result, even if the game section is long without winning the transition lottery, the transition lottery probability set in the gaming machine 10 is very low by comparing with the determined transition lottery probability If it can be determined that the player was in a state of “weak pulling, weak pulling”, without having to hesitate in the numerical value set in the transition lottery probability of the gaming machine 10, this time there is no chance It can be thought that it was inevitable just to do it. If you only have no luck this time, you can make it seem that a lottery win should be generated stochastically by continuing the game without stopping the game. As a result, it is possible to encourage the game to be continued even in a disadvantageous situation for the player that the state of not winning is continued for a long time.

In addition, the transition lottery probability that is the initial setting of the gaming machine 10 is obtained by winning the transition lottery early and the result (for example, length) of the game section of the special game is found, and similarly comparing the transition lottery probability. If it can be determined that the very high is not the direct cause of the early win and the player is in a “strong, strong” state, then he can be honestly pleased with his luck.
In this way, regardless of the state of the game, the game can be further continued and enjoyed, and an interesting game can be achieved.
Here, the “special game” includes a game in which a privilege is given to the player in a so-called assist time (AT), replay time (RT), assist replay time (ART) state, Also included are so-called big bonus games (BB) and regular bonus games (RB).
In addition, “determining the game section for a special game” is not limited to setting a parameter that directly determines the initial value of the number of games for a special game (the number of initial games allowed). In particular, parameters that can be used as a parameter for determining the game section of the special game, for example, an indirect parameter such as an initial value of the number of medals that can be acquired during the special game (initially obtainable number) are included. .
Here, “determining the game section of the special game based on the transition lottery probability” is not necessarily limited to determining the length of the game section of the special game based on the transition lottery probability. In addition, a game that determines the type of game section (game content) for a special game based on the transfer lottery probability may be included. Specifically, for example, when the transition lottery probability is high, a game section in which the number of payouts in one game is 8 is determined, but when the transition lottery probability is low, the number of payouts in one game is determined. In other words, the game content of the game section may be determined to be of a different type rather than the length of the game section so that the game section is determined to be 15 cards.

The gaming machine 10 according to the present invention is characterized by the following points. That is, in a game machine having a normal game that is normally played and a special game that is more advantageous to the player than the normal game, a lottery (hereinafter referred to as whether or not to shift from the normal game to the special game). The transition condition determining means 190 for determining a mode based on a lottery probability (hereinafter referred to as “transition lottery probability”) used for “transition lottery”) and the transition lottery probability during the normal game, The transition lottery means 330 for performing the transition lottery, and the special game zone corresponding to the mode are set in advance, and the special game zone based on the mode determined by the transition condition determination unit 190 and a special game segment determining means 200 for determining a, corresponds to one mode, the length of one transition lottery probability and one special game game section corresponds, the Line lottery probability is characterized in that it is estimated to be able to set the length of the game section of a special game.
Here, “the game section of the special game corresponding to the mode is set in advance” means that the value determined for each mode and the result (for example, length) of the game section of the special game Are determined in advance so as to have a certain relevance by an arithmetic expression, or when the mode and the length of the game section are determined according to a table (table).
In the present invention, the game section of the special game corresponding to the mode is set in advance, and the game section of the special game is determined by the mode based on the transition lottery probability in the transition lottery for shifting to the special game. ing. That is, there is a correspondence (association) between the ease of transitioning to special games (difficulty) by the mode based on the transition lottery probability and the result (for example, length) of the game section of the special game. become.
Since there is a correspondence between the mode based on the transfer lottery probability and the result (for example, length) of the special game, the special game is finished and the result (for example, length) of the special game From this result, the mode used for the transition lottery that has shifted to the special game can be estimated, and the transition lottery probability can be estimated from this mode.
Players who have been able to estimate the transition lottery probability through the mode will be the timing of winning the transition lottery in the previous (previous) normal game, and the next (current or future) normal after the end of the special game It is possible to determine whether or not the timing for winning the transition lottery by proceeding with the game is earlier or later than the timing calculated from the transition lottery probability.
In other words, the player who has been able to estimate the transition lottery probability is a normal game from the transition lottery probability set in the gaming machine determined through the mode by the game section and the end of the special game such as the previous time or this time. By comparing the result of the transfer lottery probability calculated by the number of games until the next special game is won after shifting to, the result of the previous or current transfer lottery is disadvantageous to the player The so-called "weak pull, weak pull" state, or the so-called "strong pull" It is possible to determine whether the state is “pull”.

As a result, even if the game section is long without winning the transition lottery, the transition lottery probability set for the gaming machine 10 is very low by comparing with the transition lottery probability found through the mode If it can be determined that the player was in a state of “weak pulling, weak pulling”, this time, without having to hesitate the numerical value set in the transition lottery probability of the gaming machine 10, etc. It can make you think that it was unavoidable just because there was no luck. If you only have no luck this time, you can make it seem that a lottery win should be generated stochastically by continuing the game without stopping the game. As a result, it is possible to encourage the game to be continued even in a disadvantageous situation for the player that the state of not winning is continued for a long time.
In addition, by winning the transition lottery early, the result (for example, the length) of the game section of the special game is found, and by similarly comparing the transition lottery probabilities through the mode, the initial setting of the gaming machine 10 If you can determine that the probability of a transition lottery being very high is not a direct cause of early wins, but that the player is in a "strong pull, strong pull" state, you will be glad to be lucky. be able to.
In this way, regardless of the state of the game, the game can be further continued and enjoyed, and an interesting game can be achieved.
Here, "special game" or "determine the game section of special game" is similar to the content of the description.
The gaming machine 10 according to the present invention is further characterized in that the special game section determining means 200 is configured such that the game section of the special game becomes shorter as the transition lottery probability is higher.
In the present invention, as the transition lottery probability is higher and the transition to the special game is easier, the length of the game section of the special game becomes shorter.

That is, the present invention, as the transition lottery probability is higher, it is easier to win in the transition lottery to the special game, the transition to the special game is easier, and the length of the game section of the special game is shortened, The profit for the player is reduced.
The higher the transition lottery probability, the easier it is to win the transition lottery earlier and the so-called state of shortage becomes shorter. That is, the higher the transfer lottery probability, the shorter the game section length of the special game when winning the transfer lottery and shifting to a special game. The shorter the state of the game that is not won in the transfer lottery, the shorter the game section of the special game can be suppressed, and the increase in the profit to the player can be suppressed. In other words, the shorter the state of entanglement and the earlier the transition lottery, the less the increase in profits to the player can be made. Since the profit given to the player does not have to be a large amount at once, the player who wants to win the transition lottery early by shortening the period of time that the transition lottery is not won is shortened accordingly. Can respond to the feelings.

On the other hand, in the present invention, the lower the transition lottery probability, the more difficult it is to win in the transition lottery to the special game, the harder the transition to the special game, and the longer the game section length of the special game becomes. The profit for the player during the game is increased.
If the transition lottery probability is low, it is not easy to win the transition lottery, and the so-called hang-up state is long, if the transition lottery is won and the game shifts to a special game, the length of the game section of the special game may be increased. it can. The longer the state of the fit that is not won in the transfer lottery, the longer the game section of the special game can be lengthened according to the length of the fit, and the profit to the player can be increased. That is, it is possible to increase the profit to the player by the amount of the game, and to respond to the player's feelings.
The gaming machine 10 according to the present invention further includes a plurality of rotating reels 62 that can variably display a plurality of symbols 61, and a game can be started by inserting a predetermined number of medals. According to the result of the stop operation of the rotary reel 62, the number of medals corresponding to the combination is formed to be paid out to the player, and the special game has a predetermined number of coins acquired by the player during the special game. The special game section determining means 200 is set to end when it reaches the number (hereinafter referred to as “acquirable number”), and the special game section determining means 200 has the transition lottery probability of X minutes when X is a positive integer. In the case of 1, the initial value of the number of obtainable games in the special game is set based on X.
In the present invention, when the transfer lottery probability is 1 / X, the initial obtainable number is set based on X. For example, between the transition lottery probability and the initial acquirable number such that the higher the transition lottery probability is, the smaller the number (or more) the initial obtainable number is, and the lower the transition lottery probability is, the greater (or the smaller) the initial obtainable number A predetermined relationship (relevance, correspondence) can be assigned. That is, by increasing or decreasing the transfer lottery probability (1 / X), it is possible to give a predetermined tendency such as a certain increase or decrease to the number of acquired sheets.
Since a predetermined relationship can be given between the transfer lottery probability and the initially obtainable number of pieces, if the relationship is found by continuing the game, the transfer lottery probability is determined from the result of the number of pieces acquired during the special game. The player will be able to recognize the transition lottery probability expected by the player himself, whether the current state is a strong pulling state with a strong pull, a weak pulling weak state, etc. be able to.
Conversely, the transition lottery probability is estimated on the basis of the number of games in the normal game from the end of the previous special game to the start of the current special game, and according to the result of the number acquired in the current special game, It is possible to answer whether the current state is a strong pulling state with a strong pull or a weak pulling state with a weak pull. In this way, the player also enjoys that it is possible to make an answer such as whether or not the prediction has been made by comparing the prediction with the reality.
In addition, in the gaming machine 10 such as a slot machine placed in a gaming hall or the like, an upper limit (specifically, for example, 15) of the number of medals paid out to a player in one game is determined. Normally, when the initial obtainable number is set, generally, the larger the initial obtainable number, the greater the number of games.

In the gaming machine 10 according to the present invention, the special game section determining means 200 may further be configured such that when the transition lottery probability is 1 / X when X is a positive integer, the number of initially obtainable games in the special game is Is set to be X sheets.
In the present invention, when the transfer lottery probability is 1 / X, the initial obtainable number is X. The higher the transfer lottery probability, the smaller the initial obtainable number, and the lower the transfer lottery probability, the more the initial obtainable number.

In the present invention, the higher the transition lottery probability is and the easier it is to shift to a special game, the smaller the number of initially obtainable cards. That is, according to the present invention, as the transition lottery probability becomes higher, it becomes easier to win in the transition lottery to the special game and the transition to the special game becomes easier. The profit for the player in the inside becomes small.
As a result, the higher the transition lottery probability, the earlier the transition lottery will be won, and the shorter the state of the so-called fit, the fewer the initial number of special games that can be acquired when winning the transition lottery and shifting to a special game. (As a result, the length of the game section of the special game is shortened by reducing the number of initially obtainable cards).

The shorter the status of the game that does not win the transition lottery during normal games, the less the number of initially obtainable cards in the special game and the less the increase in profits to the player during the special game. . In other words, the state of the entanglement during the normal game is short, and the earlier the transition lottery is won, the less the increase in profits to the player in the special game can be reduced. Since the profit given to the player does not have to be a large amount at a time, it is possible to respond to the player's feeling that he wants to win the transition lottery early by shortening the period of the fit. it can.
On the other hand, in the present invention, the number of special games that can be initially acquired increases as the transition lottery probability is low and the transition to the special game is difficult. Increasing the number of initially acquirable cards increases the length of the special game zone.

In other words, the lower the transition lottery probability, the harder it is to win in the transition lottery to the special game and the more difficult it is to transition to the special game. Profit increases.
As a result, the lower the transition lottery probability, the more difficult it is to win the transition lottery. It is possible to increase the profit to the player during the special game. That is, it is possible to increase the profit to the player in the special game by the amount that fits in the normal game, and to respond to the feelings of the player who is stuck.

In the present invention, specifically, for example, when the transfer lottery probability is 1/100, the initial obtainable number is 100, and when the transfer lottery probability is 1/200, the initial number of possible games is 200. Something that would be a sheet.
It is possible to clearly recognize the specific value of the transition lottery probability from the result of the number of payouts during the special game, and the transition lottery probability expected by the player himself or the current state is a strong pulling state Answers such as whether there is a weak or weak pulling state can be made accurate.
Conversely, the transition lottery probability is estimated on the basis of the number of games in the normal game from the end of the previous special game to the start of the current special game, and according to the result of the number acquired in the current special game, It is possible to accurately answer whether the current state is a strong pulling state with a strong pull or a weak pulling state with a weak pull. In this way, the player also enjoys that it is possible to make an accurate answer such as whether or not the prediction has been made by comparing the prediction with the reality.

The gaming machine 10 according to the present invention is further characterized in that the special game section determining means 200 is configured such that the game section of the special game becomes longer as the transition lottery probability is higher.
In the present invention, as the transition lottery probability is higher and the transition to the special game is easier, the length of the game section of the special game becomes longer.

That is, according to the present invention, the higher the transition lottery probability is, the easier it is to win in the transition lottery to the special game, the easier it is to transition to the special game, and the length of the game section of the special game becomes longer. Profits for players will increase.
As a result, the shorter the state of the game that is not won in the transition lottery, the longer the game section of the special game can be, and the profit to the player can be significantly increased. In other words, the lottery is frequently won in the transition lottery, the more consecutive winnings, the narrower the interval between special games, the longer the special game zone (the length of special games), the shorter Larger profits can be given to the player in the meantime, and the gaming machine 10 can be made like a explosive base where profits increase explosively.

On the other hand, in the present invention, the length of the game section of the special game is shortened as the transition lottery probability is low and the transition to the special game is difficult.
In other words, the lower the transition lottery probability, the harder it is to win in the transition lottery to the special game, the more difficult it is to shift to the special game, and the length of the game section of the special game is also shortened, and the profit to the player is remarkable Get smaller.

For the player, the transition lottery probability is low, it is difficult to shift to the special game, and even if it is finally won, the game section of the special game is short. It is possible to form a so-called large-margin state, and even if it is finally won the transition lottery, the game section of special games will be short and the profit will be slight, a state that is very disadvantageous for the player It becomes.
As a result, by setting the transition lottery probability level, it is possible to generate a high preferential state and a low preferential state for the player, and easily create a game with a rough wave of profit for the player Can do.

The gaming machine 10 according to the present invention further comprises a transition condition changing means capable of changing the transition lottery probability or mode determined by the transition condition determining means 190 at a predetermined opportunity during the normal game, and the special game section The determining means 200 is characterized by newly determining a game section of the special game based on the transition lottery probability or mode changed by the transition condition changing means.
The present invention includes "transition condition changing means capable of changing the transition lottery probability determined by the transition condition determining means 190 at a predetermined opportunity during the normal game, and the special game section determining means 200 includes the transition condition A gaming machine characterized by newly determining a game section of the special game based on the transition lottery probability changed by the changing means or the mode determined by the transition condition determining means 190 during the normal game Transition condition changing means that can be changed at a predetermined opportunity, and the special game section determining means 200 newly determines the game section of the special game based on the mode changed by the transition condition changing means. It means “characteristic gaming machine”.

In the present invention, the transition condition changing means changes the transition lottery probability or mode determined by the transition condition determining means 190 at a predetermined opportunity. The special game section determining means 200 newly determines a special game section based on the changed transition lottery probability or mode.
By changing the transition lottery probability or mode, the result (for example, length (long or short)) of the game section when the game is shifted to the special game at a predetermined opportunity during the normal game can be changed. The player's profits gained can be changed.

The transition lottery probability or mode change by the transition condition changing means may be changed to a new transition lottery probability or mode by lottery, or one transition lottery probability or mode selected from a plurality of predetermined transition lottery probabilities or modes. The mode is determined by lottery or a predetermined order, etc., and the mode is changed to the determined transition lottery probability or mode.
Specifically, in the present invention, for example, a transfer lottery probability A (for example, 1/200, the initial obtainable number of sheets at this time is, for example, 200) and a transfer lottery probability B (for example, 300) are set. 1), the transfer lottery probability A and the transfer lottery probability B are alternately used for each game. And lottery.
The present invention has been described in a sixth embodiment to be described later.

Since this invention is comprised as mentioned above, there exists an effect as described below.
According to the onset Ming, the game segment transition lottery probability and special game result (for example, length) that there is a correspondence between an special game is a game segment special play finished result (e.g. , Length), the transition lottery probability used for the transition lottery that has shifted to the special game can be estimated from the result (for example, length) of the game section, and the player's transition lottery is won It is possible to determine whether the timing to perform is earlier or later than the timing calculated from the transition lottery probability (whether it is a strong or weak state), and a gaming machine capable of performing an entertaining game Can be provided.

According to the present onset Akira, further, as the transition lottery probability is high, becomes easy to transition to a special game it is easy to win in the transition lottery to a special game, the length of the game section of the special game is shortened , The profit for the player is reduced. Thereby, even if a large amount of profits cannot be obtained at one time, it is possible to respond to the player's feeling that he / she wants to win the transition lottery early by shortening the period of fit.
Also, the lower the transition lottery probability, the more difficult it is to win in the special game transition lottery, making it difficult to transition to the special game, and the length of the game zone of the special game becomes longer and the profit to the player increases. . As a result, it is possible to respond to the feelings of the players who are interested in increasing the profits to the players as much as they can.
According to the onset bright, further, the increase or decrease in migration lottery probability (X min of 1), it is possible to apply a predetermined trend of such a constant increase or decrease the payout number, the tendency Ya by the player continues If the relevance can be determined, the player's own prediction of the lottery probability, etc., and whether the current state is a strong pulling state or a weak pulling weak state This makes it possible for the player to enjoy the fact that by comparing the prediction with the reality, the player can make an answer such as whether or not the prediction has been made.

According to the present onset Akira, further, it is possible to transition lottery probability is higher, also to reduce profits to be able to reduce the initial acquisition possible number of special game player. Thereby, even if the number of initially obtainable sheets is small, it is possible to respond to the player's feeling that he wants to win the transition lottery early by shortening the period of the fit.
Further, as the transfer lottery probability is lower, the number of special games that can be initially acquired can be increased and the profit to the player can be increased. As a result, it is possible to respond to the player's feeling that he wants to increase the number of initially acquirable cards as much as possible.

According to the present onset Akira, further, the more likely to shift to a special game with high migration lottery probability, a longer length of the gaming section of the special game. As a result, the shorter the state of the game that is not won in the transition lottery, the longer the game section of the special game can be lengthened, the profit to the player can be increased, and the profit will explode at a stretch. It can be like a table.

On the other hand, in the present invention, the length of the game section of the special game is shortened as the transition lottery probability is low and the transition to the special game is difficult. As a result, the longer the state of the game that is not won in the transition lottery, the shorter the game section of the special game, and the formation of a state where the player is provided with very little profit.
As a result, by setting the transition lottery probability level, it is possible to easily generate a high preferential state and a low preferential state for a player, and easily create a game with a rough wave of profit for the player can do.
According to the onset bright, furthermore, it can change the length of the game segment when migrating lottery probability is shifted to the special game at a predetermined trigger during normal game by being changed (long and short), Special It is possible to provide a gaming machine that can change a player's profits obtained during a game, and that can make the feeling of expectation and gameability rich.

Below the medal payout port 28, a dish-shaped medal tray 26 that opens upward is formed to store medals paid out from the medal payout port 28. When the number of credited medals is less than the maximum number of credit medals, the acquired medals are added to the number of credit medals without being paid out from the medal payout exit 28 until the number reaches 50.

  The gaming machine 10 according to the present embodiment enables a game to be started by inserting a predetermined number of medals by operating the max bet switch 34 or inserting medals. Then, when the start switch 40 is pressed, the rotation of the rotary reel 62 is started to start the game, and a role lottery is performed using a lottery table corresponding to each game state of the main controller 110 described later. Then, based on the operation timing of the stop switch 50 corresponding to each rotary reel 62 and the result of the winning lottery, the gaming machine 10 stops the rotation of the rotating reel 62 so as to match the result of the winning lottery. The gaming machine 10 determines whether the combination of symbols 61 constituting the winning combination is a predetermined effective line (when the combination of symbols 61 of a predetermined combination is aligned on the line, depending on the combination of symbols 61 at the time of stoppage. This is a line to which the profit is awarded, and is hereinafter referred to as the active line 86.) When the player stops on the line, the player is given a predetermined profit such as winning a prize and paying out a predetermined number of medals. . As a result, one game is completed.

“Effective line 86” means a line to be determined by the stop symbol determining means 150 described later, and a “winning” of a small role described later has a combination of symbols 61 corresponding to the role on the effective line 86. Means. The effective line 86 of the present embodiment is composed of only one broken line connecting the middle stage of the left rotating reel 64 and the middle rotating reel 66 and the lower stage of the right rotating reel 68.
As shown in FIG. 2, “red 7”, “blue 7”, “white 7”, “bell (BEL)”, “replay” are formed on the surfaces of the left rotating reel 64, the middle rotating reel 66, and the right rotating reel 68. (REP) ”,“ Cherry 1 (CH1) ”,“ Cherry 2 (CH2) ”,“ Watermelon 1 (WM1) ”,“ Watermelon 2 (WM2) ”,“ BAR ”are formed. ing.

  These designs 61 are formed by sticking a tape on which each design is printed on the outer peripheral surface of the rotary reel 62. Note that the number (frame number) of the symbol 61 in FIG. 2 is not a physical number attached to the outer peripheral surface of the rotary reel 62, but is a virtual number for controlling the stop of each symbol 61. This is for specifying a specific symbol 61 in the program.

  As shown in FIG. 3, a control device 100 for controlling the overall operation of the gaming machine 10 is formed inside the gaming machine 10. This control device 100 receives a main control device 110 that controls the game state by advancing the game, and receives information (commands) from the main control device 110, and controls effects according to the progress of the game. A sub-control device 300 that controls the effect state is provided in order to perform an effect of notifying the player of information related to game content.

  Here, the operating state of the slot machine based on the control of the main control device 110 is referred to as a gaming state, and the operating state of the slot machine based on the control of the sub control device 300 is referred to as an effect state. The main control device 110 and the sub control device 300 are connected by one-way communication from the main control device 110 to the sub control device 300 in order to prevent unauthorized operation of the main control device 110. Communication in the reverse direction from the control device 300 to the main control device 110 is not performed (that is, not bidirectional communication). The main controller 110 receives inputs from the start switch 40, the stop switch 50, the max bet switch 34, and the checkout switch 36, performs a lottery drawing, and controls the operations of the reel unit 60 and the storage / dispensing means 24. Sub-control device 300 receives a signal from main control device 110 and controls the operation of rendering device 70 such as display device 84. On the output side of the sub-control device 300, the display device 84, the speaker 72, and the effect lamp 78 as the effect device 70 are connected.

  Although not particularly illustrated, the main board having the main control device 110 and the sub board having the sub control device 300 are housed in dedicated board cases, respectively. Specifically, the main control device 110 is housed in the main board case, and the sub control device 300 is housed in the sub board case. The main board case is fixed to the upper part inside the housing 12 and the sub board case is fixed to the left side from the front inside the housing 12.

  The main control device 110 and the sub control device 300 are configured by a microcomputer including a CPU, a ROM, a RAM, and an I / O port (not shown). The CPU has an interrupt function such as a timer interrupt, and executes various programs by executing a program stored in the ROM. The ROM stores programs executed by the CPU and fixed data such as various tables, and the RAM stores a temporary storage area when the CPU executes the programs, for example, the state of the gaming machine 10 It is used as a storage area for storing the area and the lottery result of the role lottery.

  In the gaming machine 10 according to the present embodiment, a normal game that is normally performed is provided. Notifying the replay time (RT) state in which the probability of winning a replaying role (replaying role) is higher (or lower) than this normal game, the stop operation order of the stop switch 50, the winning symbol 61, etc. Is provided with an assist time (AT) state for assisting to stop the combination of symbols 61 related to the winning combination on the effective line 86. Note that the RT state is controlled by the main control device 110, and the AT state is mainly controlled by the sub-control device 300. Of course, the devices for controlling each state (main control device 110, sub-control device 300) are not limited to those described above, and each state may be controlled by the other control device, A part of the means may be partially controlled by another control device and may be controlled across both control devices. At this time, direct transmission from the sub-control device 300 to the main control device 110 is not performed, but the main control is performed by notifying the predetermined stop operation order from the sub-control device 300 and stopping the player. Information can be transmitted indirectly to the device 110. The assist time (AT) state is formed to be a special game that is more likely to give a benefit that is beneficial to the player than in the normal state.

  That is, in the gaming machine 10 according to the present embodiment, the game can be transferred by winning a normal game that is a normal game and a lottery (transition lottery) that determines whether or not to shift during the normal game. It has a special game (AT game) that can give more benefits than a normal game.

  An AT game as a special game can be started when a predetermined start condition is achieved, and can be ended when a predetermined end condition is achieved. Specifically, an AT game as a special game can be started when a lottery result of a combination lottery, when a predetermined transition combination is won, or when a predetermined transition lottery is won by a transition lottery means 330 described later, The game can be terminated when the number paid out to the player during the AT reaches a predetermined number (so-called acquirable number). In addition, it is not limited to these start conditions and end conditions, You may set to other conditions, such as ending by reaching | attaining a predetermined game frequency.

  The AT game as a special game can be executed until the number of medals that can be acquired according to the result of the predetermined transition lottery reaches the acquirable number, but this executable acquirable number can be added by a predetermined lottery. Is set. When determining this extra, it is possible to perform an effect when adding to the number of special games that can be acquired, so-called an extra effect, and as this extra effect, a reel effect using the rotary reel 62 and a display device 84. Both the display effect using and are formed to be executable.

  The reel effect is an effect using the rotating reel 62, and the three rotating reels 62 are rotated and stopped, the rotation direction is changed, the rotation speed is changed, the rotation acceleration is changed, and the predetermined symbol 61 is rotated. This can be done by various means. The display effect is an effect performed by a moving image or a still image displayed on the display device 84 which is the liquid crystal display device 84. Note that sound, music, sound effects, and the like from the speaker 72 are appropriately performed along with the display effect.

The AT game as a special game includes a first state that can be repeatedly executed after the AT game start condition is achieved, a second state that can be repeatedly executed after the end of the first state, and an end of the second state. A third state that can be repeatedly executed later is provided (see FIG. 5).
The first state is started with the start of the AT game, and in the second state, the sign effect that suggests the execution of the additional effect can be executed, and the additional effect can be executed in the third effect. Yes.

  The main control device 110 includes a role lottery means 120, a reel control means 130, a stop symbol determination means 150, a normal game control means 160, an RT control means 170, a bonus game control means 180, a transition condition determination means 190, a special game section determination means. 200, state transition means 240, reel effect execution means 245, payout control means 250, transition lottery means 330, and transmission means 260. Details of each means will be described later.

Note that these means, in particular, the transition condition determining means 190, the special game section determining means 200, the transition lottery means 330, and the like may be included in the sub control device 300 instead of the main control device 110. At that time, since direct transmission of data from the sub-control device 300 to the main control device 110 is not performed, the order of the stop operation by the stop switch 50 is performed by the sub-control device 300 when such transmission is necessary. Is transmitted to the main control device 110 through indirect transmission means such as the player performing the stop operation in the order of the stop operation. The
With the above configuration, the main control device 110 performs lottery drawing, controls the rotation and stop of the rotating reel 62, determines the stop symbol 61 when all the rotating reels 62 stop, and advances the game. It will function as a means.

The main control device 110 is for controlling the game and is for proceeding with the game. Hereinafter, the game in the present embodiment will be described.
When the specified number of bets (three) is set, one active line 86 (see FIG. 1) is set. In the gaming machine 10 according to the present embodiment, 3 is set as the prescribed bet number. As a method for setting the bet number, there are a method for inserting a medal from the medal insertion slot 38 and a method for setting a credit medal as the bet number by operating the max bet switch 34. Then, if the start switch 40 is operated on condition that the specified number of bets (3) is set, the number of bets is confirmed and either of a plurality of winning combinations is won by the winning lottery means 120 or A lottery lottery (role drawing) is performed. At almost the same time as the winning lottery, it is determined whether or not a predetermined time (4.1 seconds in this embodiment) has elapsed since the start of rotation of the rotary reel 62 in the previous game. When elapses, rotation of all three rotary reels 62 starts. In the present embodiment, the prescribed number is set to 2 only during a bonus game (CBB) described later.

  In the present embodiment, when a role is roughly classified, a small role (a role accompanied by paying out medals), a re-playing role (a role that can start the next game without using a medal owned by the player, so-called replay) Role) and a transitional role (a role accompanied by a transition of the gaming state).

After the rotation of the rotary reel 62 is started, a predetermined condition (in this embodiment, a process of accelerating the rotary reel 62 is executed, and then a predetermined sensor detects that the rotational position of the rotary reel 62 is the reference position. Is established, the stop switch 50 can be operated (stop operation enabled state).
Thereafter, when one of the three stop switches 50 is operated, the rotation of the rotary reel 62 corresponding to the stop switch 50 is stopped. When all the three stop switches 50 have been operated, the rotation of all three rotary reels 62 is stopped.

  At this time, when a combination of predetermined symbols 61 is arranged on the effective line 86, processing corresponding to the combination of symbols 61 is performed. The gaming machine 10 according to the present embodiment is formed such that a profit is given to a player when a predetermined combination of symbols 61 is arranged on the active line 86. For example, when the combinations of symbols 61 corresponding to the small combination are arranged on the active line 86, the number of medals corresponding to the small combination is awarded to the player.

  In the gaming machine 10 according to the present embodiment, as a gaming state, a normal state (which is a general game) and a bonus (CBB) are won by the role lottery means 120 in the normal state. Nevertheless, when the symbol 61 related to the bonus transition combination does not stop on the active line 86, in the RT1 state (CBB winning state) that shifts from the normal state, and in this RT1 state (CBB winning state) There is provided a bonus state (CBB state) in which the symbol 61 relating to the bonus transition combination is shifted when it stops on the active line 86 and the profit given to the player can be greater than the normal state (see FIG. 5). 4).

  The bonus state is achieved when a bonus transition combination as a transition combination is selected and a combination of symbols 61 corresponding to the bonus transition combination (for example, “blue 7, blue 7, BAR”) is aligned on the active line 86. It is a game that starts from the next game of the game.

  In addition, even if the combination of symbols 61 corresponding to the bonus transitional combination is not prepared on the active line 86 in the game at the time of winning, the bonus transitional combination will correspond to the bonus transitional combination on the effective line 86 after the next game. The winning combination will remain valid until 61 combinations are available. Other combinations will be invalid after the next game if the combination of symbols 61 corresponding to the combination is not available on the active line 86 in the game at the time of winning. The bonus state ends when the total number of medals paid out to the player during the bonus state exceeds a preset number.

  In the present embodiment, a challenge bonus state (CBB state) mainly controlled by the main controller 110 is provided as a bonus state. The challenge bonus state facilitates winning of a small role by placing all the small roles in a winning state. It should be noted that during the challenge bonus state, the stop is stopped within 75 ms from the time of operation of the stop switch 50 in a predetermined case, and the so-called number of sliding symbols is smaller than that in the normal state. Specifically, in the challenge bonus state according to the present embodiment, the right rotating reel 68 has the symbol 61 at the display position at the timing when the right stop switch R is stopped, and one frame above the symbol 61. This is a so-called “single frame slide” state that can be stopped within the range of two frames with the symbol 61. The challenge bonus state according to the present embodiment ends with a payout number exceeding 28. Of course, this end condition is not limited to 28 sheets, and other sheets may be used.

  In addition, when the combination of symbols 61 corresponding to the re-playing role (replaying role) is arranged on the active line 86, the medal is not paid out, but the bet number is automatically used in the next game without using the medal owned by the player. Can be set and played.

  The role lottery means 120 is a means provided in the main control device 110, and is for performing a lottery (role lottery) of winning or losing a plurality of roles in response to an operation of the start switch 40. . The role lottery means 120 has a lottery table for determining whether or not a winning combination is won for each of a normal state, a bonus state (CBB state), and an RT1 state (CBB winning state). Correspondingly, a plurality are provided and stored in the ROM of the main controller 110. The role lottery means 120 compares a predetermined lottery data with a random number extracted from random numbers generated by a predetermined random number generator (random number generator circuit) having a loop counter that repeatedly counts integer values within a predetermined range. Then, it is determined whether or not it is won. The process by the combination lottery means 120 is performed in step 113 (see FIG. 8) described later.

  It should be noted that the lottery probability used for the role lottery of the role lottery means 120 is configured to be changeable by the manager of the game hall within a pre-programmed range. Specifically, a plurality of setting values (specifically, by operating a setting change switch (not shown) in the housing 12 for changing a setting value that is a value for defining the lottery probability) Can change the lottery probability by selecting any one of 1 to 6). In the present embodiment, six set values 1 to 6 are provided, and the lottery probability is defined to be advantageous to the player in principle as the set value increases.

The reel control means 130 is a means provided in the main control device 110, and is for stopping the rotation of each rotary reel 62. The reel control means 130 stops the rotation of each rotary reel 62 based on the lottery result of the winning lottery means 120 and the rotation position of the corresponding rotary reel 62 when each stop switch 50 is operated. Note that the reel control means 130 may set a condition for stopping whether or not the order (stop operation order) when each stop switch 50 is operated to stop meets a predetermined condition as necessary. The processing by the reel control means 130 is performed in step 114 (see FIG. 8) described later.
Further, the reel control means 130 can execute a predetermined reel effect in a so-called freeze state in which the progress of the game is stopped.

  The stop symbol determination means 150 is a means provided in the main controller 110, and stores the combination of symbols 61 on the effective line 86 when all the rotary reels 62 are stopped, and determines a winning or the like. is there. Note that the processing by the stop symbol determination means 150 is performed in step 115 (see FIG. 8) described later.

  The normal game control means 160 controls the progress of the normal game. Here, the normal game means a replay time (RT) by the RT control means 170 described later and a game state other than the CBB by the bonus game control means 180. Note that the winning probability of the re-gamer during the normal game is set lower than the replay time (RT) state.

In the present embodiment, the RT control means 170 controls the replay time (RT) state.
The bonus game control means 180 controls the bonus game, specifically, the CBB state.
The transition condition determining means 190 is for determining a lottery probability (transition lottery probability) used for a lottery (transition lottery) as to whether or not to shift from a normal game to an AT as a special game. The transition condition determining means 190 includes a mode determination lottery table, which will be described later, and lottery means for performing random lottery using the mode determination lottery probability of the mode determination lottery table.
In this embodiment, there are three modes (modes A, B, and C) with different transition lottery probabilities, the transition lottery probability in mode A is set to 1/100, and the transition lottery probability in mode B Is set to 1/200, and the transition lottery probability in mode C is set to 1/300 (see FIG. 7).

  The transition condition determining means 190 is set to perform a lottery (mode lottery) for determining a transition lottery probability at the timing when a predetermined gaming state starts or ends. Specifically, the transition condition determination means 190 performs mode lottery at the end of the special game (AT). Of course, the opportunity for carrying out the lottery is not limited to this, and other predetermined occasions (for example, the timing at the start of special games (AT), the timing at the start of normal games, the role lottery, etc.) It may also be the timing at which a specific combination determined in advance by the combination lottery of the means 120, the timing at which a predetermined number of games have passed since these predetermined triggers, or the like. Further, when a specific combination is won in the combination lottery, the mode may be determined based on the extracted random number value (for example, the remainder obtained by dividing the extracted random number value by 3 is 1, 2, or 0) Depending on the mode A, B, and C).

  The transition condition determination means 190 performs a mode lottery for determining a mode to be used from among the three modes described above. In this mode lottery, the lottery probability (mode determination lottery probability) for determining each mode is stored in the mode determination lottery table shown in FIG. 6, and the mode determination lottery probability of each mode A, B, and C is Each is set to one third (see FIG. 6). In addition, this mode determination lottery probability is not limited to the numerical value mentioned above, and may be another numerical value. Further, the mode determination lottery probability of each mode may not be the same numerical value. Furthermore, a plurality of mode determination lottery tables may be prepared in advance so as to depend on (relevant to) the mode type determined last time. Specifically, for example, when the previous mode is mode A, the mode determination lottery table in which the mode determination lottery probability that mode C is easily selected is set is used.

  Similarly to the role lottery means 120, the lottery means of the transition condition determination means 190 repeatedly counts a random number range set from predetermined mode determination lottery probability data (see FIG. 6) and an integer value within a predetermined range. Which mode is set by comparing with random numbers extracted from random numbers generated by a predetermined random number generation means (random number generation circuit) having a loop counter (which transition lottery probability is set) Determine.

  Here, the transition lottery probability is not limited to the above-described numerical value, but may be another numerical value, and the number of modes described above is not limited to three, but one Or two may be sufficient and four or more may be sufficient. Further, the transfer lottery probability is not limited to the value selected from the fixed values as described above, and the calculation means calculates the predetermined transfer lottery probability by lottery from within a predetermined range using a predetermined arithmetic expression. You may make it calculate.

In addition, here, the transition condition determining means 190, when determining the transition lottery probability, once determines the mode, and determines the transition lottery probability that is preset for each determined mode, The present invention is not limited to this, and the transition lottery probability may be determined directly without involving a mode.
The special game section determining means 200 is for determining a special game (AT) game section based on the transfer lottery probability determined by the transfer condition determining means 190. The special game section determining means 200 is set so that the game section of the special game becomes shorter as the transition lottery probability is higher.

  Here, in the present embodiment, “determine a game section for a special game” is to finally determine a game section for a special game (which affects the length of the game section (which affects the length, The number of medals that can be obtained during an AT as a special game (so-called acquirable number) is determined. The AT as a special game is set to end when the number paid out to the player during the AT reaches the acquirable number, and the maximum number of payouts to be paid out in one game is a predetermined number. Since it is set to (15), the length of the special game is limited by determining the obtainable number. Of course, it is also possible to determine the number of games that can be executed in a special game that is a direct parameter (so-called possible number of games), and other direct game zones that can be determined (can be limited). Or indirect parameters, or a combination of these parameters.

  In the present embodiment, specifically, the special game section determining means 200, when X is a positive integer and the transition lottery probability is 1 / X, the initial value of the number that can be acquired in the special game ( The initial obtainable number) is set to X. Specifically, when X is 100 and the transition lottery probability is 1/100, the special game section determining unit 200 sets the initial number of special games that can be acquired to 100. In addition, the special game section determining means 200 sets the initial obtainable number of special games to be 200 when X is 200 and the transition lottery probability is 1/200. Further, the special game section determining means 200 sets the initial obtainable number of special games to be 300 when X is 300 and the transition lottery probability is 1/300 (see FIG. 7). .

  The state transition means 240 performs transition of each state of the first state (normal state during AT), the second state (a precursor state of the extra effect during AT), and the third state (addition effect state during the AT) during the special game. It is for the purpose.

In the special game (AT), when it is determined to execute any of the additional effects, it is possible to acquire the additional effects.
Specifically, the state transition means 240 shifts to the second state when the execution of the extra effect is determined in the first state, and shifts to the third state after the end of the second state.
The state transition means 240 transitions to the first state when the right to add the performance is not left after the end of the third state.

  The state transition means 240 makes the transition to the second state as long as the right of the additional effect remains after the end of the third state, transitions to the third state after the end of the second state, and after the end of the third state. A similar loop process is set to be repeated based on the remaining number of additional presentation rights.

  The reel effect execution means 245 is for executing a reel effect as an extra effect by the rotating reel 62 operating as the effect device 70. This reel effect execution means 245 executes the reel effect of the extra effect.

The payout control means 250 is for performing predetermined processing such as medal payout based on the determination result of the stop symbol determination means 150. The payout control means 250 pays out medals when it is determined that the small role is winning as a result of the determination by the stop symbol determining means 150.
The transition lottery means 330 performs the transition lottery during the normal game using the transition lottery probability determined by the transition condition determination means 190, and determines whether to shift to the AT state by lottery (transition lottery). To do. Specifically, the transfer lottery means 330 is set to perform a transfer lottery in each game during a normal game. Of course, the trigger for carrying out the transfer lottery is not limited to this, and other predetermined triggers (for example, the timing at which a predetermined gaming state starts or ends, or the predetermined number of games has elapsed since the predetermined trigger) Timing, etc.).

When the transition lottery of the transition lottery means 330 is won, the special game section determining means 200 determines the number of special games (AT) that can be initially acquired based on the transition lottery probability as described above.
The transmission means 260 is for transmitting a signal to the sub-control device 300.

The sub-control device 300 includes a receiving unit 310 and an AT control unit 320.
The receiving unit 310 receives a signal from the transmitting unit 260.
The AT control means 320 controls the effect state in the AT state. Specifically, the AT control means 320 includes a display effect execution means 370, an end determination means 380, and an extra effect determination execution means 390.

The display effect executing means 370 is for executing a display effect performed by the display device 84.
The end determination means 380 determines whether or not an AT state end condition is satisfied, and ends the AT state when the end condition is satisfied. The determination of the end of the AT state is not particularly shown, but is performed separately from the flowchart described later. When the AT state end condition is satisfied, the AT state is forcibly ended. The AT condition end condition is set when the total number of medals paid out during the AT reaches the acquirable number. Of course, the end condition is not limited to this, and when the predetermined number of games is ended, when the predetermined stop operation order is not followed, or when a predetermined predetermined combination is won, etc. It may be set or a combination thereof.
The addition effect determination execution means 390 determines whether or not the AT state is added and the number of times by a lottery (addition effect acquisition lottery) according to a predetermined opportunity (specifically, winning of a predetermined predetermined role) in the AT state. To do.

Note that these means may be arranged in the main control device 110, and the display effect execution means 370, the end determination means 380, and the added effect determination execution means 390 are arranged in the main control device 110 instead of the sub control device 300. You may arrange.
With the above configuration, the sub control device 300 receives a signal from the main control device 110 and performs an effect accompanying the progress of the game.

As shown in FIG. 4, the transition states in the main controller 110 include a normal state, an RT1 state (CBB winning state), and a bonus state (CBB state).
The normal state is a game state in which a normal game controlled by the normal game control means 160 is performed. When the bonus (CBB) is won by the role lottery by the role lottery means 120 in the normal state, the normal state is shifted to the RT1 state (CBB winning state). In the RT1 state (CBB winning state), the replay time state (RT state) has a higher replay lottery probability than the normal state.

  In the present embodiment, the bonus (CBB) is set to be won within a few games during the normal state, and the gaming state seems to have a high ratio of being played in the RT1 state (CBB winning state). Is set to

The RT state in this RT1 state (CBB winning state) is a gaming state in which a re-game controlled by the RT control means 170 is won with high probability. In the RT state, when the combination of symbols 61 (blue 7, blue 7, BAR) of the CBB bonus transition combination is prepared, the CBB winning state, so-called RT state, shifts to the bonus state (CBB state). This bonus state (CBB state) is controlled by the bonus game control means 180.
In the bonus state (CBB state), when a predetermined number, for example, 28 pieces are paid out, the CBB state is shifted to the normal state.

  As shown in FIG. 5, the transition state during the special game (AT) includes the normal state during the AT as the first state, the precursor state of the additional effect during the AT as the second state, and the AT as the third state. Three types are provided: a medium-up stage production state.

In the normal state during AT as the first state, as a result of the role lottery, at a predetermined opportunity such as winning a predetermined predetermined role, as a result of the extra effect acquisition lottery process, the winner was won and execution of the extra effect was decided In this case, it is possible to shift to the second state and the third state, and it is possible to acquire an additional effect.
The special game (AT) is not particularly shown, but is set to end when a predetermined end condition such as reaching a predetermined number of obtainable games is achieved.
In the third state, the additional effect is executed in the additional effect state during the AT. In the precursor state of the additional effect during the AT in the second state, the precursor effect suggesting execution of the additional effect in the third state can be executed.

In any of the first state, the second state, and the third state, it is possible to acquire the right to execute the additional effect, and to count the number of rights to execute the additional effect.
Transition to the third state after the end of the second state, transition to the first state by satisfying a predetermined condition after the end of the third state, and return to the second state by satisfying other conditions. After the end of the two states, there is a case where the same loop process is repeated after the transition to the third state.

  In any state, the special game (AT) is configured to end when a predetermined end condition of the special game (AT) is satisfied, but the end timing is not necessarily limited to this. It is not something. For example, when a special game (AT) satisfies an end condition, the special game (AT) ends immediately in the first state, and in the second state and the third state, the special game (AT) ends after the third state ends. Also good.

As shown in FIG. 6, the mode determination lottery table of the transition condition determining means 190 stores the mode determination lottery probability (common one third) of each mode (modes A, B, and C).
In the present embodiment, the final numerical values of the mode, the transfer lottery probability, and the initial obtainable number are as shown in FIG. Specifically, when the mode in the left column is determined by the transition condition determining means 190, and the transition lottery probability (1 / X) is determined by this mode, the special game section determining means 200 is based on the transition lottery probability. Then, the initial obtainable number of sheets (X) in the right column is set. Note that the initial obtainable number may be set directly from the transition lottery probability without going through the mode.

Based on the flowchart shown in FIG. 8, a general game control process executed by the main controller 110 for each game will be described.
In step 112, the main controller 110 determines whether or not the start switch 40 has been operated. Here, if it is determined that the start switch 40 has been operated, the main controller 110 makes it impossible to set the number of bets. Thereafter, the process proceeds to the next step 113. On the other hand, if it is determined that the start switch 40 has not been operated, step 112 is again performed.

  As a premise of this step 112, a betting number setting process is performed. In this betting number setting process, it is determined whether or not a prescribed betting number is set as the betting number. Specifically, the main controller 110 determines whether or not the number of medals set as the number of bets on the game has reached a specified number of bets (2 or 3).

  In step 113, the role lottery means 120 performs a role lottery process. At this time, the result of the winning lottery is transmitted from the main control device 110 to the sub-control device 300. When the combination lottery process ends, the process proceeds to the next step 114.

In step 114, rotation variation processing of the rotary reel 62 in the reel unit 60 is performed. After the rotation reel 62 reaches a predetermined rotation speed, when the main controller 110 operates the stop switch 50 corresponding to the rotation reel 62 that is rotating, the reel control means 130 causes the rotation reel 62 to The rotation is stopped. The stop operation order corresponding to the winning combination of the stop switch 50 (left stop switch L, middle stop switch C, right stop switch R) at this time is stored in a predetermined storage area formed in the main control device 110. Then, it is read out in the subsequent processing.
Further, after all stop operations are completed, the rotation stop information of all the rotation reels 62 is transmitted from the transmission unit 260 of the main control device 110 to the reception unit 310 of the sub control device 300. Then, when the rotation variation process for all the rotary reels 62 is completed, the process proceeds to the next step 115.

In step 115, the stop symbol determination means 150 performs a determination process such as winning a prize as to whether or not a combination of symbols 61 of a predetermined role is aligned with a combination of symbols 61 on the active line 86. Here, the data of the determination result of the determination process such as winning is transmitted from the main control device 110 to the sub-control device 300. Then, when the determination process ends, the process proceeds to the next step 116.
In step 116, the payout control means 250 performs a payout process corresponding to the determination result of the stop symbol determining means 150. Note that if the result of the determination is that payout is not required, payout processing is not performed. Then, the process ends.

Based on the flowchart shown in FIG. 9, the initial obtainable number determination process performed by the main controller 110 will be described. The flowchart shown in FIG. 9 is performed by the main control device 110, but may be performed by the sub control device 300 through indirect information transmission from the sub control device 300 to the main control device 110. Is.
The flowchart shown in FIG. 9 is a process performed for each game in a normal game. In addition, you may make it implement in other than a normal game.

First, in step 212, a transfer lottery process is performed by the transfer lottery means 330. This transition lottery process is performed in each game during a normal game. Then, the process proceeds to the next step 213.
In step 213, it is determined whether or not the transfer lottery in step 212 has been won. If it is determined that the transfer lottery has been won, the process proceeds to the next step 214, and if it is determined that the transfer lottery has not been won, the process ends.

In step 214, the special game section determining means 200 performs processing for setting the initial obtainable number based on the transfer lottery probability. When the transition lottery probability determined by the transition condition determining unit 190 is 1 / X by the special game section determining unit 200, the initial obtainable number is set to X.
Specifically, when the transition lottery probability determined by the transition condition determining unit 190 is 1/100, the special game section determining unit 200 sets the initial acquirable number to 100. Further, the special game section determining means 200 sets the initial obtainable number to 200 when the transfer lottery probability determined by the transfer condition determining means 190 is 1/200. Further, the special game section determining means 200 sets the initial obtainable number to 300 when the transfer lottery probability determined by the transfer condition determining means 190 is 1/300. Then, the process proceeds to next Step 215.

In step 215, a notification effect process for the number of initially obtainable images is performed. Specifically, the display effect executing means 370 notifies the player of the set initial obtainable number via the display device 84 or the like. Then, the process ends.
The initial acquisition number may be notified at the start timing of the special game (AT), or at the start timing of the special game (AT), only a part is notified and the special game (AT) is performed. After paying out the notified number, the remaining game may be notified and the special game (AT) may be continued. At the start timing of the special game (AT), only a part of the special game (AT) is notified. After playing a game (AT) and paying out the number of the noticed, perform a specific effect (for example, battle effect, etc.), and after the specific effect ends, inform the rest and continue the special game (AT) You may make it do.
In FIG. 10, a description will be given with reference to a flowchart showing the determination process of the transfer lottery probability.

First, in step 309, it is determined whether or not the current timing is a predetermined trigger time in each game. Specifically, it is determined whether or not it is the timing (game) at the end of the special game (AT). If it is determined that the current game is at a predetermined opportunity, that is, the timing (game) at the end of the special game (AT), the process proceeds to the next step 310, and the current game is performed at the predetermined opportunity. If it is not time, that is, it is determined that it is not the timing (game) at the end of the special game (AT), the process ends.
In step 310, the transition condition determination means 190 performs a mode lottery process to determine which mode from among a plurality of modes. Then, the process proceeds to next Step 311.
In step 311, the transition condition determination means 190 determines a transition lottery probability (1 / X) corresponding to the mode determined by the mode lottery process.

The transition condition determination means 190 determines the transition lottery probability according to the mode determined by the mode lottery process. Specifically, the transition condition determination means 190 sets 1/100 as the transition lottery probability (1 / X) when the determined mode is mode A, and transitions when the determined mode is mode B. 1/200 is set as the lottery probability (1 / X), and when the determined mode is mode C, 1/300 is set as the transition lottery probability (1 / X). Then, the process ends.
In the present embodiment, the game section of the special game (AT) is determined based on the transfer lottery probability in the transfer lottery for shifting to the AT as the special game. That is, there is a correspondence (association) between the ease of transitioning to special games (difficulty) and the length of the game section of the special game based on the transition lottery probability.

When there is a correspondence between the transfer lottery probability and the length of the special game section, the player executes the game, the special game ends, and the result of the length of the special game section is found From the result of the length of the game section, the player can estimate the transfer lottery probability used for the transfer lottery that has shifted to the special game (AT).
The player who has been able to estimate the transition lottery probability will determine the timing of winning the transition lottery in the previous (previous) normal game and the next (current or future) normal game after the end of the special game (AT). It is possible to determine whether or not the timing or the like for proceeding and winning the transition lottery is earlier or later than the timing calculated from the transition lottery probability.

In other words, the player who was able to estimate the transition lottery probability until the transitional lottery probability determined by the game section and the transition to the normal game from the end of the special game such as the previous or this time to win the next special game By comparing the result of the transfer lottery probability calculated by the number of games of the game, the result of the transfer lottery of the previous time or this time is biased toward the disadvantage (bad side) against the player. Determine whether the pull was weak or weak, or whether it was in a so-called "strong pull, strong" state that would be biased toward the player's advantage (the better) be able to.

  As a result, even if the game lot is long without winning the transition lottery during normal games, the transition lottery probability according to the original setting of the gaming machine 10 is very low by comparing with the determined transition lottery probability If it can be determined that the player was in a state of “weak pulling, weak pulling”, this time, without having to hesitate the numerical value set in the transition lottery probability of the gaming machine 10, etc. It can make you think that it was unavoidable just because there was no luck. If you only have no luck this time, you can make it seem that a lottery win should be generated stochastically by continuing the game without stopping the game. This makes it possible to encourage the game to continue even in a disadvantageous situation for the player that the state in which the special game transition lottery is not won during a normal game continues for a long period of time.

In addition, when the transition lottery is won early, it is early that the transition lottery probability that is the initial setting of the gaming machine 10 is very high by comparing the transition lottery probability by the same method as described above. If it can be determined that the player's “strong pull, strong pull” state is not the direct cause of winning, then he can be honestly glad that he was lucky.
In this way, regardless of the state of the game, the game can be further continued and enjoyed, and an interesting game can be achieved.

In the present embodiment, the length of the game section of the special game becomes shorter as the transition lottery probability is higher and the transition to the special game is easier.
That is, in this embodiment, the higher the transition lottery probability is, the easier it is to win in the transition lottery to the special game, the easier it is to shift to the special game, and the length of the game section of the special game is shorter. Therefore, the profit for the player is reduced.

  The higher the transition lottery probability, the easier it is to win in the transition lottery earlier, so that the so-called inset state becomes shorter or the inset state does not occur. In other words, the higher the transfer lottery probability, the shorter the game section length of the special game can be made when winning in the transfer lottery and shifting to a special game. The shorter the state of the game that is not won in the transfer lottery, the shorter the game section of the special game can be suppressed, and the increase in the profit to the player can be suppressed. In other words, the shorter the state of entanglement and the earlier the transition lottery, the less the increase in profits to the player can be made. Since the profit given to the player does not have to be a large amount at a time, it is possible to respond to the player's feeling that he wants to win the transition lottery early by shortening the period of the fit. it can.

On the other hand, in this embodiment, the length of the game section of the special game becomes longer as the transition lottery probability is lower and the transition to the special game is difficult.
In other words, the lower the transition lottery probability, the harder it is to win in the special game transition lottery, the harder it is to enter the special game, and the longer the game section length of the special game is, the game during the special game. The profit to the person becomes large.

  The lower the transition lottery probability, the more difficult it is to win in the transition lottery, and the longer the so-called entanglement state becomes. At this time, when the player wins the transition lottery and shifts to the special game, the length of the game section of the special game can be increased. The longer the state of the game that is not won in the transition lottery, the longer the game section of the special game can be lengthened according to the length of the game, and the profit to the player can be increased. That is, if it gets stuck, the profit to a player can be increased, and it can respond to the feeling of the stuck player.

Furthermore, it demonstrates concretely.
In the present embodiment, when the transfer lottery probability determined by the transfer condition determining means 190 is 1 / X, the number of initially acquirable pieces by the special game section determining means 200 is X.
The higher the transfer lottery probability, the smaller the initial obtainable number, and the lower the transfer lottery probability, the more the initial obtainable number.
In the present embodiment, as the transition lottery probability is higher and the transition to the special game is easier, the number of initially obtainable numbers decreases. In other words, in this embodiment, the higher the transition lottery probability, the easier it is to win in the transition lottery to the special game and the easier it is to shift to the special game, but the initial obtainable number in the special game decreases, The benefit to the player during the special game is reduced.

As a result, the higher the transfer lottery probability, the earlier the win in the transfer lottery, and the shorter the so-called state of engagement, the fewer the initial number of special games that can be acquired when winning in the transfer lottery and moving to a special game (In the end, as a result, the length of the game section of the special game is shortened by reducing the initial number of obtainable cards).
In the present embodiment, the shorter the number of entrants that will not win the transition lottery during normal games, the smaller the initial number that can be acquired during special games, and the increase in profits to players during special games. Can be suppressed. In other words, the state of the entanglement during the normal game is short, and the earlier the transition lottery is won, the less the increase in profits to the player in the special game can be reduced. Since the profit given to the player does not have to be a large amount at a time, it is possible to respond to the player's feeling that he wants to win the transition lottery early by shortening the period of the fit. it can.

On the other hand, in the present embodiment, the number of special games that can be initially acquired increases as the transition lottery probability is low and the transition to the special game is difficult. As a result, the number of initially obtainable cards increases, and the length of the game section for special games increases.
In other words, the lower the transition lottery probability, the harder it is to win in the transition lottery to the special game and the more difficult it is to transition to the special game. Profit increases.
As a result, the lower the transition lottery probability, the more difficult it is to win in the transition lottery, and the longer the so-called inconsistency state, the more the initial number of special games that can be acquired when winning in the transition lottery and transitioning to a special game. It is possible to increase the profit to the player during the special game. That is, it is possible to increase the profit to the player in the special game by the amount that fits in the normal game, and to respond to the feelings of the player who is stuck.

  In the present embodiment, specifically, when the transfer lottery probability is 1/100, the initial obtainable number in the special game (AT) is 100, and the transfer lottery probability is 1/200. The initial acquirable number is 200, and when the transfer lottery probability is 1/300, the initial acquirable number is 300. The transition lottery probability is recognized from the result of the number of special games (AT) that can be acquired, such that if the initial number of special games (AT) that can be acquired is 100, the transition lottery probability is 1/100. And the current situation is consistent with the expectation that the player himself predicted the transition lottery probability, whether the current state is a strong pulling state with a strong pull, or a weak pulling state with a weak pull You can make an answer such as whether or not.

Conversely, the transition lottery probability is estimated based on the number of games in the normal game from the end of the previous special game (AT) to the start of the current special game (AT), and gained in the current special game. Depending on the result of the number of sheets, it is possible to answer whether the current state is the same as the current state of the prediction, such as whether the current state is a strong pulling state or a weak pulling state. . For example, if the current special game is won with 203 normal games since the end of the previous special game, the number of initially obtainable numbers in the current special game is estimated when the transition lottery probability is estimated to be 1/200. Is 300, it turns out that the actual transition lottery probability is 1/300, and the player is currently in a stronger pulling state than the player expected. Prove. In other words, since this number of games (203 in the above example) was required before the transition to the special game (AT), the transition lottery probability is probably about this (1/200 in the above example). And the estimated transition lottery probability is compared with the number actually acquired in the special game (AT) (300 in the above example) to determine whether the current state is strong or weak (described above In this example, the player can recognize the strong state).
In this way, the player's expectation can be compared with the actual (answer matching) based on the transfer lottery probability, the number of payouts, etc., and the player can answer whether the expectation was true or not. The pleasure of being able to do it also occurs.
In the present embodiment, when X is a positive integer and the transfer lottery probability is 1 / X, the initial obtainable number in the special game is set to be X. It is not limited. When the transfer lottery probability is 1 / X, it is only necessary that the initial obtainable number in the special game is set based on X. For example, when the transfer lottery probability is 1/200 (X = 200), the initial obtainable number is set to X + 5, and specifically, it may include 205. is there.
Specifically, for example, in the above case, the initial obtainable number is X + 1, X + 2, X + 3,..., X-1, X-2, X-3,. In this case, X + α sheets (where α is an integer (including minus)) may be used. Similarly, X × 0.1 sheets, X × 0.2 sheets,..., X × 2 sheets, X × 3 sheets,..., X / 2 sheets, X / 3 sheets,. -It may be set such as X × β (where β includes a decimal and a fraction in addition to an integer).
In the present embodiment, there is a predetermined correspondence (relevance) between the transfer lottery probability (or mode) and the initial obtainable number, which is the initial value of the number of medals that can be obtained by the player during the special game. Was provided. The payout number (acquired number) as a condition for ending the special game is based on the payout number of medals to be paid out to the player. Instead of this payout number, the game machine is used for the player to start the game. A so-called pure increase number (specifically, the number of payouts during a special game-the number of coins inserted during a special game) that reflects the number of coins inserted into the medals may be used. That is, there may be a predetermined correspondence (relevance) between the net increase number and the transfer lottery probability (or mode).

(Second Embodiment)
This embodiment will be described with reference to FIG.
In the first embodiment, as the transition lottery probability is higher, the special game (AT) game section is set to be shorter. In the present embodiment, the transition lottery probability is higher and special. It is characterized in that the length of the game section of the special game is longer as the transition to the game (AT) is easier.

That is, in this embodiment, the higher the transition lottery probability, the easier it is to win in the transition lottery to the special game, the easier it is to shift to the special game, and the length of the game section of the special game is longer. As a result, the benefit to the player increases.
As a result, the shorter the state of the game that is not won in the transition lottery, the longer the game section of the special game can be, and the profit to the player can be significantly increased. In other words, the more frequent the lottery wins, the narrower the interval between special games, and the longer the special game area (the length of special games), giving the player greater profits. It is possible to make the gaming machine 10 like a explosive base where profits increase explosively at a stretch.

On the other hand, in this embodiment, the length of the game section of the special game becomes shorter as the transition lottery probability is lower and the transition to the special game is difficult. In other words, the lower the transition lottery probability, the harder it is to win in the transition lottery to the special game, the more difficult it is to shift to the special game, and the length of the game section of the special game is also shortened, and the profit to the player is remarkable Get smaller.
For the player, the transition lottery probability is low, it is difficult to shift to the special game, and even if it is finally won, the game section of the special game is short. It is possible to form a so-called large-margin state, and even if it is finally won the transition lottery, the game section of special games will be short and the profit will be slight, a state that is very disadvantageous for the player It becomes.
As a result, by setting the transition lottery probability high or low, it is possible to easily generate a high preferential state and a low preferential state for the player, and a game with a rough wave of profit for the player is easy. Can be formed.

As shown in FIG. 11, specifically, the special game section determination means 200 sets the initial obtainable number of special games to be 300 when the transition lottery probability is 1/100. In addition, the special game section determining means 200 sets the initial obtainable number of special games to be 200 when the transition lottery probability is 1/200. Further, the special game section determining means 200 is set so that the initial number of special games that can be acquired is 100 when the transition lottery probability is 1/300. Of course, the transfer lottery probability and the initial obtainable number are not limited to the above-mentioned values, and the higher the transfer lottery probability, the larger the initial obtainable number, resulting in a longer AT game section length. It suffices if it is set to be.
Other configurations, operations, and effects are the same as those in the first embodiment, and descriptions thereof are omitted.

(Third embodiment)
This embodiment will be described with reference to FIG.
In the first embodiment, the transfer lottery probability is determined by a lottery using random numbers. That is, in the first embodiment, in the transition lottery probability determination process, the mode is first determined by lottery using a random number by the mode lottery process, and the transition lottery probability predetermined for each mode is determined. In the present embodiment, instead of lottery, the number of games in a predetermined range (specifically, after the last special game (AT) is completed and until the current special game (AT) is won) The mode is determined according to the number of games), and the transition lottery probability determined in advance for each mode is determined.

The transition condition determining means 190 according to the present embodiment is configured so that the number of games within a predetermined range (specifically, from the end of the last special game (AT) until the current special game (AT) is won) Counting means for counting the number of games) and storing the counted number, and a calculating means for dividing the number of games counted by this counting means by 3 and calculating the remaining number (1, 2, 0) And a transition lottery probability determining means for determining the transition lottery probability via the mode based on the remainder of the numerical value calculated by the calculating means.
Note that the number of games in the predetermined range described above is set to the number of normal games from the end of the previous special game (AT) until winning the current special game (AT), but is not limited to this. Is not to be done. As long as the number of games is not fixed to a specific number and can be changed to some extent at random, another number of games may be used. Specifically, for example, in a case where the number of special games (AT) is increased by a lottery and varies randomly, the number of special games (AT) may be set to the number of games. . In addition, the number of games or the time from the start or end of a normal game or special game (AT) until a predetermined specific winning combination or winning may be set.
In FIG. 12, a description will be given with reference to a flowchart showing the determination process of the transfer lottery probability.

First, in step 409, it is determined whether or not the current timing (game) is a predetermined trigger time in each game. Specifically, it is determined whether it is the timing at the end of the special game (AT). If it is determined that the current game is at a predetermined opportunity, that is, the timing (game) at the end of the special game (AT), the process proceeds to the next step 410 and the current game is performed at a predetermined opportunity. If it is not time, that is, it is determined that it is not the timing (game) at the end of the special game (AT), the process ends.
In step 410, the counting means (not shown) of the transition condition determining means 190 collects the number of games of the normal game counted from the end of the previous special game until the winning of the current special game (AT). . Then, the process proceeds to next Step 411.
In step 411, the calculation means calculates a remainder obtained by dividing the collected number of games by 3, and the mode determination means determines the mode based on the remainder.

  The calculating means (not shown) of the transition condition determining means 190 calculates a remainder (1, 2, or 0) obtained by dividing the number of games counted by the counting means by 3. Then, the transition lottery probability determining means (not shown) determines the mode (A, B or C) based on the remaining numerical value. Specifically, the mode determining means (not shown) sets the mode for determining the transfer lottery probability to mode A when the remainder obtained by dividing the count number by 3 is 1, and the remainder is 2 The mode is set to mode B. If the remainder is 0, the mode is set to mode C. Then, the process proceeds to next Step 412.

In step 412, a transition lottery probability corresponding to the determined mode is set by a transition lottery probability determining unit (not shown) of the transition condition determining unit 190.
Specifically, the transition lottery probability determining means (not shown) sets the transition lottery probability to 1/100 in the case of mode A, and sets the transition lottery probability to 1/200 in the case of mode B. In the case of mode C, the transfer lottery probability is set to 1/300.
Then, the process ends.

  In the present embodiment, the transfer lottery probability is distributed through the mode by the remainder obtained by dividing the number of games of the normal game by 3, but the present invention is not limited to this. In this embodiment, three modes are used and the remainder obtained by dividing by 3 is used to distribute the three transition lottery probabilities. However, 2, 4, 5,... N transitions. When distributing the lottery probabilities, a plurality of transition lottery probabilities may be distributed according to the remainder obtained by dividing the number of games by a numerical value of 2, 4, 5,.

In the present embodiment, without using lottery means such as random number generating means, the transfer lottery probability can be equally distributed by a simple calculation formula using the number of games of the normal game. Since the lottery means is not used for this portion, even when the number of distributions increases, it is possible to avoid burdening the storage capacity and the like, and the processing time can be processed in a short time.
Other configurations, operations, and effects are substantially the same as those in the first embodiment, and descriptions thereof are omitted.

(Fourth embodiment)
This embodiment will be described with reference to FIGS.
In the first embodiment, the special game (AT) has been completed when the predetermined initial acquirable number is reached, but in the present embodiment, the number of games executed during the special game (AT) is reduced. The game is set to end when a predetermined number of games (so-called possible number of games) is reached.

  When the transition lottery probability is 1 / X when X is a positive integer, the special game section determining means 200 according to the present embodiment has an initial value of the number of games that can be played in the special game (the number of games that can be initially played). Is set to be (m × X) times. Here, m is a predetermined coefficient (specifically, a numerical value equal to or less than 1), and is specifically set to a numerical value of 0.1. Of course, the coefficient m is not limited to 0.1, and may be other numerical values. Here, when the numerical value of m × X (multiplication of the coefficient m and the numerical value X) is not an integer, the integer value is obtained by rounding off the decimal part. In addition, you may make it round off or round up after a decimal point instead of rounding off.

  In the present embodiment, the final numerical values of the mode, the transfer lottery probability, and the initial number of possible games are as shown in FIG. Specifically, the mode of the left column is determined by the lottery of the transition condition determining means 190, and when the predetermined transition lottery probability (1 / X) of the middle column is determined by this mode, the special game section determining means 200 is for setting the initial number of possible games (m × X) in the right column based on the transition lottery probability (1 / X).

  Based on the flowchart shown in FIG. 14, the process of determining the initial number of games that can be performed by the main controller 110 will be described. The flowchart shown in FIG. 14 is performed by the main control device 110, but may be performed by the sub control device 300 through indirect information transmission from the sub control device 300 to the main control device 110. Is.

The flowchart shown in FIG. 14 is a process performed for each game in a normal game. In addition, you may make it implement in other than a normal game.
First, in step 512, the transfer lottery process is performed by the transfer lottery means 330. This transition lottery process is performed in each game during a normal game. Then, the process proceeds to next Step 513.

In step 513, it is determined whether or not the transition lottery in step 512 has been won. If it is determined that the transfer lottery has been won, the process proceeds to the next step 514. If it is determined that the transfer lottery has not been won, the process ends.
In step 514, the special game section determining means 200 performs an initial game possible number setting process based on the transfer lottery probability. When the transition lottery probability determined by the transition condition determining unit 190 is 1 / X by the special game section determining unit 200, the initial possible game number is set to (m × X) times.

Specifically, the special game section determining means 200 sets the initial number of possible games to 0.1 × 100, that is, 10 times when the transfer lottery probability determined by the transfer condition determining means 190 is 1/100. . Further, the special game section determining means 200 sets the initial number of possible games to 0.1 × 200, that is, 20 times when the transfer lottery probability determined by the transfer condition determining means 190 is 1/200. Further, the special game section determining means 200 sets the initial obtainable number to 0.1 × 300 times, that is, 30 times when the transfer lottery probability determined by the transfer condition determining means 190 is 1/300. Then, the process proceeds to next Step 515.
In step 515, a notification effect process of the number of possible initial games is performed. Specifically, the display effect executing means 370 notifies the player of the set initial number of possible games through the display device 84 or the like. Then, the process ends.
Note that, as in the first embodiment, the initial number of possible games may be notified collectively or may be notified separately.

According to the present embodiment, when the transition lottery probability used for the transition lottery to the special game is 1 / X, the initial game possible number of times for the special game is m × X times. In this way, the higher the transition lottery probability, the smaller the initial number of possible games, and the lower the transition lottery probability, the greater the number of possible initial games. As a result, as the transition lottery probability tends to fall low, the number of possible initial games can be increased, the more profitable to the player, the more profitable to the player, Can be in line with the feelings of the person. Further, the higher the transition lottery probability is, the more the number of possible initial games can be reduced, and the profit to the player can be suppressed. The amount of profits in special games may be small, so do not get stuck, or do not stay for a long period of time, and be in line with the player's feelings that they want to move to special games as soon as possible (frequency) Can do. Thus, by setting the transition lottery probability to a predetermined numerical value, it is possible to easily make the game contents in accordance with the feelings of various players. Depending on the transition lottery probability used for the special game transition lottery, the number of possible special games can be set to various numbers, and as a result, the length of the special game (AT) section can be easily controlled. be able to. In addition, by changing only the coefficient m, the initial number of possible games in all modes, that is, the length of the special game section in all modes, without changing the entire stored data of each mode individually. It can be changed easily.
Other configurations, operations, effects, and the like are substantially the same as those described in the first embodiment, and descriptions thereof are omitted.

(Fifth embodiment)
The present embodiment will be described with reference to FIG.
In this embodiment, FIG. 15 is used instead of FIG. 13 in the fourth embodiment.

In the fourth embodiment, as the transition lottery probability is higher, the number of possible initial games is reduced and the game section of the special game (AT) is set shorter. In the present embodiment, As the transition lottery probability is higher and the transition to the special game (AT) is easier, the number of possible initial games is increased and the length of the game section of the special game is longer.
That is, in this embodiment, the higher the transition lottery probability is, the easier it is to win in the transition lottery to the special game, the easier it is to shift to the special game, and the number of times that the special game can be initially played increases. As a result, the length of the game section is increased, and the profit for the player is increased.
As a result, the shorter the state of the fit that does not win the transition lottery, the more the number of possible initial games and the longer the game section of the special game can be, and the profit to the player can be remarkably increased. . In other words, the more consecutive the game, the narrower the interval between special games and the longer the special game area (the length of the special game), so that a larger profit can be given to the player. It is possible to make the gaming machine 10 like a explosive table which increases explosively at a stretch.

  On the other hand, in the present embodiment, the lower the transition lottery probability is and the more difficult it is to shift to the special game, the smaller the number of possible initial games and the shorter the length of the special game zone. In other words, the lower the transition lottery probability, the more difficult it is to win in the transition lottery to the special game, and it is difficult to shift to the special game, and the initial number of times that the special game can be played is reduced. The length is also shortened, and the profit to the player is significantly reduced.

For the player, the transition lottery probability is low, it is difficult to shift to the special game, and even if it is finally won, the game section of the special game is short. It is possible to form a so-called large-margin state, and even if it is finally won the transition lottery, the game section of special games will be short and the profit will be slight, a state that is very disadvantageous for the player It becomes.
As a result, by setting the level of the transition lottery probability, it is possible to easily form a rough wave game consisting of a high preferential state and a low preferential state as a benefit to the player by increasing or decreasing the number of initial games possible Can do.

As shown in FIG. 15, specifically, the special game section determining means 200 sets the initial number of possible special games to be 30 when the transition lottery probability is 1/100. Also, the special game section determining means 200 sets the initial number of possible special games to be 20 when the transition lottery probability is 1/200. Further, the special game section determining means 200 is set so that the initial number of times that the special game can be played is 10 when the transfer lottery probability is 1/300. Of course, the transition lottery probability and the initial number of games that can be played are not limited to the above-described values, and the higher the transition lottery probability, the larger the number of initial games that can be played, resulting in a longer AT game section length. It suffices if it is set to be.
Other configurations, operations, and effects are the same as those in the fourth embodiment, and descriptions thereof are omitted.

(Sixth embodiment)
The present embodiment will be described with reference to FIG.
In the present embodiment, the main control device 110 shown in FIG. 3 is provided with a transition condition changing means (not shown) that can change the transition lottery probability determined by the transition condition determining means 190 at a predetermined trigger during normal game. I have.

Furthermore, the special game section determining means 200 newly determines a special game section based on the transfer lottery probability changed by the transfer condition changing means (not shown).
Based on the flowchart shown in FIG. 16, the transition lottery probability changing process executed by the main controller 110 during the normal game will be described. The flowchart shown in FIG. 16 is performed by the main control device 110, but may be performed by the sub control device 300 via indirect information transmission from the sub control device 300 to the main control device 110. .
First, in step 610, it is determined whether or not the transition lottery probability has already been set in the normal game started after the previous special game (AT) has ended. If it is determined that the transition lottery probability has already been set during the normal game, the process proceeds to the next step 611, and if it is determined that the transition lottery probability has not yet been set during the normal game, The process ends.

  In step 611, it is determined whether or not it is a predetermined trigger for changing the transfer lottery probability by a transfer condition changing means (not shown). Specifically, it is determined whether or not the number of normal games counted from the end of the previous special game (AT) is a predetermined number of games. Specifically, the predetermined number of games is set to 20, 50, 100, 200, 500, 800, and 1000 times. Of course, the value is not limited to the value of the number of games, and may be a value of another number of games. For example, it may be set for each number of games such as an even number or an odd number, and it has a predetermined timer that is timed from the end of the previous special game, and this timer keeps time. It may be set so that a predetermined trigger comes every predetermined time (every hour, every three hours, etc.). In addition, this predetermined opportunity may be a timing at which a winning combination (changed winning combination) set in advance for changing the transfer lottery probability in the winning lottery of the winning lottery means 120 is won. When it is determined that it is a predetermined opportunity, the process proceeds to the next step 612, and when it is determined that it is not a predetermined opportunity for changing the transition lottery probability, the process ends.

In step 612, the transition lottery probability is changed by a transition condition changing means (not shown). Specifically, the mode A transition lottery probability is changed to the mode B transition lottery probability, the mode B transition lottery probability is changed to the mode C transition lottery probability, and the mode C transition lottery probability is changed to the mode A transition lotion probability. The lottery probability is changed. Of course, the change of the transfer lottery probability is not limited to the contents described above. Specifically, for example, in changing mode A, the order of A, B, C, the order of A, A, B, B, C, C, the order of A, B, C, B, A, etc. It may be changed in accordance with the order determined in advance. Moreover, you may make it change the transfer lottery probability corresponding to each mode by lottery using a random number.
Then, the process ends.

In the present embodiment, the transition condition changing means (not shown) determines the transition lottery probability determined by the transition condition determining means 190 for a predetermined opportunity (specifically, a normal game counted from the end of the special game). (When it is a predetermined number of games). The special game section determining means 200 newly determines a game section for the special game based on the changed transition lottery probability as in the case described above.
By changing the transfer lottery probability, you can change the length (long or short) of the game section when transitioning to the special game at a predetermined opportunity during the normal game, and the player's gain during the special game Profit can be changed.
Here, in this embodiment, the transition condition changing means (not shown) changes the transition lottery probability, and the special game section determining means 200 determines the game section of the special game based on the transition lottery probability. However, instead of the “transition lottery probability”, the “mode” described in the first embodiment or the like may be used as a medium. That is, the transition condition changing means (not shown) may change the mode, and the special game section determining means may determine the game section for the special game based on the mode.
Other configurations, operations, and effects are substantially the same as those in the first embodiment, and a description thereof will be omitted.

(Seventh embodiment)
This embodiment will be described with reference to FIG.
In the first to sixth embodiments described above, the transition condition determining means 190 determines the transition lottery probability used for the transition lottery as to whether or not to shift from the normal game to the special game (AT) as the transition condition. It was.
On the other hand, in the present embodiment, the transition condition determined by the transition condition determining means 190 is that the special game is unconditionally unconditional when the number of games of the normal game from the end of the previous special game reaches the predetermined number of games. This is set to the so-called ceiling game count.
Specifically, FIG. 17 is used in this embodiment instead of FIG. 7 described in the first embodiment. The transition condition determining means 190 sets the number of ceiling games in mode A to 100 times, sets the number of ceiling games in mode B to 200 times, and sets the number of ceiling games in mode C to 300 times. Is.

Then, the special game section determining means 200, based on the number of ceiling games determined by the transition condition determining means 190 (100 times, 200 times, 300 times), the initially obtainable number (100, 200, 300 in order). The game section of the special game is determined by determining the number of cards.
That is, when the number of games on the ceiling of mode A is set to 100 times, the special game section determining means 200 sets the initial obtainable number to 100. When the number of games on the ceiling of Mode B is set to 200, the special game section determining means 200 sets the initial number of obtainable games to 200. When the number of games on the ceiling of mode C is set to 300, the special game section determining means 200 sets the initial obtainable number to 300.
Other configurations, operations, and effects are substantially the same as those in the first embodiment, and a description thereof will be omitted.

(Eighth embodiment)
This embodiment will be described with reference to FIG.
In the first to seventh embodiments described above, the special game section determining means 200 determines the game section of the special game based on the transition lottery probability determined by the transition condition determining means 190, and in that case As the parameters for determining the game section of the special game determined in the above, the initial obtainable number of games and the initial number of games that can be played are used. In this embodiment, as a parameter for determining the game section of the special game, the initial value of the number of notification effects for assisting the player's stop operation in the AT state during the special game (AT), the so-called number of navigations Is used as the initial value of the initial navigation possible number of times. The notification effect for assisting the player's stop operation in the AT state is that the stop operation order of the stop switch 50 (so-called recommended stop operation order) is determined in advance, and the stop switch 50 is in accordance with the recommended stop operation order. The display device 84 notifies the recommended stop operation order when the payout number or the like is advantageously set to the player by operating the player.

In the first embodiment, the special game (AT) is completed when the predetermined number of acquirable games is reached, but in this embodiment, the number of times of navigation executed during the special game (AT) is predetermined. When the number of times (so-called initial navigation possible number) is reached, the AT state during the special game (AT) is set to end.
When the transition lottery probability is 1 / X when X is a positive integer, the special game section determining means 200 according to the present embodiment has an initial navigation possible number of times of (n × X) times. It is set so that it may become. Here, n is a predetermined coefficient, and is specifically set to a numerical value of 0.1. Of course, the coefficient n is not limited to 0.1, but may be other numerical values. Here, when the numerical value of n × X (multiplication of the coefficient n and the numerical value X) does not become an integer, the integer value may be obtained by rounding off the decimal part. In addition, you may make it round off or round up after a decimal point instead of rounding off.

In the present embodiment, the final numerical values of the mode, the transfer lottery probability, and the initial navigation possible number are as shown in FIG. Specifically, the mode of the left column is determined by the lottery of the transition condition determining means 190, and when the predetermined transition lottery probability (1 / X) of the middle column is determined by this mode, the special game section determining means 200 is for setting the initial navigable number of times (1 / (n × X)) in the right column based on the transition lottery probability (1 / X).
