Description

  In the present invention, a medal (coin) is used as a game medium, and a plurality of rotating reels (rotors) are arranged in a predetermined arrangement on a winning line. More particularly, the present invention relates to a slot machine that provides a new specific gaming state that has never existed before.

In general, a slot machine displays a plurality of (usually three) symbols such as predetermined pictures, numbers, characters, etc. on the outer peripheral surface when a player inserts a game medal as a game medium and presses a start lever. This reel is a game machine in which the reel starts rotating, the reel is stopped by pressing a stop button at an arbitrary timing, and a predetermined number of medals are paid out according to the arrangement of the symbols of the stopped reels.
In such a slot machine, normally, in order to increase the fun of the game, a plurality of reels are automatically controlled with a certain probability so that the symbols attached to each reel are arranged in a predetermined arrangement on the winning line. The winning control called so-called “internal winning lottery” is performed.

The internal lottery control is such that when the game is started by depressing the start lever, the internal winning lottery is automatically performed in the slot machine for each game and the winning content is determined. The reel stop position is controlled accordingly, and if a lottery result is won, regardless of the timing when the player presses the stop button, the symbols attached to each reel within a certain range will be the winning content. The stop is automatically controlled so as to obtain a corresponding arrangement (winning arrangement), and a predetermined amount of medals according to the winning arrangement is paid out.
More specifically, when a certain content is won as a result of the internal lottery, the rotating reels are within a certain range (for example, within the range of 4 symbols from the position of the corresponding symbol) and the player's Regardless of the timing at which the stop button is pressed, the symbols are arranged in a predetermined winning line (for example, “7, 7, 7”, “BAR, BAR, BAR”, etc.) according to the winning content on the predetermined winning line. Stop control (winning control) is performed.

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

Here, in the slot machine game in which a predetermined amount of medals is paid out by the reel stop control as described above, a general game that is completed for each game and a specific game that is completed in units of multiple games (so-called “big hit”, "Combined items") are provided.
As a result of the internal lottery, the general game is a “small role” in which a small amount (for example, 2 or 7) of medals is paid out per game, or a “replay ( In a game state in which stop control such as “Replay” ”or“ Loose ”without medal payout is performed, the effect of the lottery result of this general game is valid only for that game, and the effect disappears in subsequent games.
In general, a slot machine game is a repetition of a general game performed in one game unit, except for a specific game (act) that occurs with a certain probability.

On the other hand, a specific game (community) means that when a predetermined “big win” is won as a result of the internal lottery, a specific game state starts when a predetermined condition is satisfied in that game or the next game. The game is played once or a plurality of times under different control from the general game, and the specific game state is ended when a certain condition is satisfied.
For example, a so-called “bonus game” called a specific gaming state advantageous to the player is known. This bonus game is “winning (flag established)” for bonus games such as “Regular Bonus (RB)” and “Big Bonus (BB)” that allow a large amount of medals to be paid out as a result of lottery per internal. Then, the winning effect is maintained until the symbol of the reel in the game or the next and subsequent games becomes a predetermined winning arrangement (for example, “7, 7, 7”), the reel stops at the winning symbol, and “ When “winning (start)”, the player enters a specific game state for one or several games thereafter, and medals are paid out at a high payout rate that cannot be obtained during a general game.

Specifically, when a regular bonus (RB) is won / winned, control for a bonus game in which several games become one set is performed. The lottery and reel control are performed so that a predetermined symbol arrangement with a combination and a large amount of payouts is continuously arranged, and 100 or more medals are paid out.
In addition, when the big bonus (BB) is won / winned, the above-mentioned regular bonus is controlled in several sets (for example, three sets), and the game is played so that hundreds of medals are paid out. Be controlled.
As described above, the conventional slot machine has the greatest feature that a large amount of medals are paid out in a specific gaming state caused by a big win (see, for example, Patent Document 1-2). ).

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

In other words, there are only the types of slot machines that can be paid out by jackpots so far, and all slot machines are common in this respect. In this situation, the slot machine game is monotonous and does not look good. There was a possibility that it was felt.
In addition, even if a jackpot that increases the payout is provided in this way, in the case of a so-called “weak pull” player, it is not easy to win the jackpot winning, and as a result, the game itself loses its interest, Could stop the game.

In addition, there is generally an upper limit on the number of payouts during jackpots, and there are limits to the number of winning medals that a player can win with a single jackpot.
Furthermore, jackpots with large payouts are the target of fraud (goto) using so-called bodily sensation machines, etc. From this point of view, it is considered necessary to take some measures and review of the mass payout system with jackpots. It came to be able to.

On the other hand, in order to increase freshness, novelty, etc., changing the conventional gaming system of winning and winning a specific gaming state by jackpot of internal lottery has penetrated the players. Familiar gaming systems will be lost, which may cause unnecessary confusion and customer churn.
In addition, slot machine games are operated under certain regulations and standards. Even if the game system is changed to a completely different one because of the freshness and fun of the game, Adoption was difficult.
Furthermore, even if a new game system is adopted, it is meaningless unless it is easy to understand for the player, and it is particularly important that the game content and the progress of the game can be easily understood.

For this reason, it has become desirable to develop a slot machine with a new game system that is more attractive and easy to understand while following the previous game system. A new slot machine has not been realized.
The inventor of the present application, following diligent research, follows a conventional game jackpot system by lottery inside a slot machine and a method of starting and ending a specific game, and is innovative, attractive, and understood by the player This has led to the creation of a new slot machine that is easy to do.

  In other words, the present invention has been proposed to solve the problems of the conventional slot machine, and in a specific game state generated as a result of a lottery per internal game, the game is reduced so that the number of balls is reduced compared with that in a general game. By controlling the game and ending the specific gaming state in which the number of games is reduced when the predetermined conditions are met, it is expected that all players regardless of beginners, advanced players, etc. It is possible to provide unprecedented surprise, thrill, and surprising game performance of decreasing the number of balls, and it can greatly reduce the possibility of being targeted for fraud. The purpose is to provide a slot machine full of new appeal that does not exist.

  In order to achieve the above object, the slot machine of the present invention stops a plurality of reels that start rotating by a start operation so that symbols on each reel are in a predetermined winning arrangement, as described in claim 1. This is a slot machine in which medals corresponding to winning symbols are paid out, a lottery is performed for each game, and each game is completed in units of one game according to the result of the lottery, or a plurality of games Control means for controlling the specific game state to be completed in units is provided, and the control means is configured to control the game so that the payout rate in the specific game state is lower than the payout rate in the general game state.

According to the slot machine of the present invention configured as described above, the general gaming state and the specific gaming state are controlled by the control of the control unit in the slot machine. In the specific gaming state to be performed, the game is controlled so that the payout rate is lower than that in the general gaming state.
Specifically, by setting the lottery table used in the internal lottery and the number of payouts at the time of winning to a predetermined value, the winning combination with a large amount of payout in the general gaming state is continuously won and won, and specified. By continuously generating a lost combination with no payout in the gaming state, it is possible to lower the payout rate in the specific gaming state and to increase the payout rate in the general gaming state than in the specific gaming state.

As a result, when the general gaming state continues, a large amount of payout is obtained and the number of acquired medals increases, and when a big hit and the specific gaming state is reached, the number of payouts is less than the general gaming state, and as a result, the specific gaming state When entering, the medal earned in the general gaming state will decrease.
That is, in the present invention, the normal game in the normal state is more advantageous to the player than the specific game that is a big hit, and the player acquires as many medals as possible during the general game state. The game is performed so that the specific game state does not occur, and when the specific game state is generated / started, the game is performed so as to end the specific game state as soon as possible.

As in the case of a bonus game in a conventional slot machine, the specific gaming state is generated by winning a predetermined jackpot as a result of the internal winning lottery performed for each game (flag is established), and the game or next time A game of “Decrease time (decrease time: GT)” that starts (wins) and stops by stopping at a predetermined symbol arrangement (for example, “skull / skull / skull”) in subsequent games. Start as a state.
Then, the game state of this ball reduction time is terminated, for example, by arranging predetermined stop symbols in the specific game state, and is provided as a specific game state that continues until a certain number of games are consumed. Alternatively, the game can be terminated when the total number of medals paid out in the specific gaming state reaches a certain number, as in the case of the gaming state of a bonus game with a large amount of payout.

As a result, in the present invention, a player who is continuously playing an advantageous game in the general game by a new specific game state called a ball deduction time draws a jackpot as a result of the internal winning lottery, The situation will occur and the number of balls will be reduced, so even weak players can fully enjoy the advantageous game state in general games, if you are an advanced player, do not win a big hit, You can enjoy an unprecedented game and game characteristics, such as winning a large amount of payouts by aligning winning symbols as much as possible in general games while preventing the jackpot that was drawn from starting.
Therefore, in the slot machine of the present invention, regardless of the level or skill of players such as beginners and advanced players, any player can enjoy an advantageous game in general games, and the thrill, surprise, and unexpectedness of a specific game can be achieved. Furthermore, it is possible to enjoy satisfaction, relief, etc. at the end of the specific gaming state.

For the player, he can enjoy the thrill of the big hit, which reduces the number of balls that do not know when it will occur, and the satisfaction and sense of accomplishment of the advantageous ball status in the general gaming state during that time. Surprise and shock when it occurs, and a sense of relief and satisfaction when it ends, giving you an unprecedented thrilling and attractive slot machine with high surprise and satisfaction.
In addition, jackpots with fewer balls than regular games are less likely to be targets of fraud, and general games that are completed in units of one game are cumbersome and difficult to shoot with bodily sensation devices. Therefore, as a result, illegal acts such as bodily sensations can hardly be performed, and a highly safe gaming machine can be realized.

More specifically, in the slot machine of the present invention, as described in claim 2, the control means ends the specific gaming state when the total number of medals paid out in the game in the specific gaming state reaches a predetermined number. This is a configuration to be made.
According to a third aspect of the present invention, the control means may be configured to end the specific gaming state when the reel stop symbols become a predetermined arrangement in the game in the specific gaming state.

According to the slot machine of the present invention having such a configuration, a specific gaming state in which the number of balls is reduced is reduced when a certain number of winnings / payouts occur during the specific gaming state, It can be terminated when it is ready.
As a result, the player arranges a predetermined stop pattern and stop arrangement (for example, “Angel” pattern, “Angel / Angel / Angel” array, etc.) for escape time reduction, or a conventional bonus. As in the case of the game, it can be understood that the specific gaming state continues until a certain number of payouts are obtained, and the game content of the slot machine according to the present invention can be reliably grasped. Then, it is possible to concentrate on the game with the goal of having a certain number of payout and escape symbols, and to enjoy satisfaction and relief at the end of the specific gaming state.

In addition, by setting the probability of winning combination and the number of winnings / payouts during the decrease in payout time, or the probability of occurrence of a specific escape symbol, the payout rate and total payout amount during the payout reduction time can be set arbitrarily. In this way, it is possible to arbitrarily set the number of digested games required before the game is finished and the adjustment of the game play rate during the general game.
Therefore, in the slot machine of the present invention, as with the conventional slot machine, by setting the payout rate for each gaming machine, for example, adjustment according to the business target of the gaming hall, setting of the sales stand at the time of new opening, etc. Therefore, it is possible to provide a gaming machine with high versatility and expandability that can be directly applied to an existing game hall.

  In the slot machine of the present invention, as described in claim 4, after the control means wins the specific gaming state by lottery for each game, the reel stop symbols in the game or the next game and the predetermined arrangement are Thus, the specific gaming state is started.

According to the slot machine of the present invention configured as described above, the specific gaming state that is the time to decrease the number of balls is the result of the internal winning lottery performed for each game as in the case of the bonus game in the conventional slot machine. , It is generated by winning a predetermined jackpot (flag is established), and it is started by stopping at a predetermined symbol arrangement (for example, “skull / skull / skull / skull”) in the game or the next and subsequent games. ing.
As a result, the internal winning lottery and jackpot system, the start method after the flag is established, the internal winning notification system that indicates the flag is established, etc., follow the game method almost the same as the conventional bonus game with a large amount of payout. It can be provided as an easy-to-understand game machine that allows players to easily understand the game system and game content, and can be provided as a highly versatile and highly scalable game system that can be applied to existing slot machines as it is. .

  Further, in the slot machine of the present invention, as described in claim 5, the control means controls the game to a plurality of specific gaming states having different payout rates or total payout numbers according to the lottery result for each game. As a configuration.

According to the slot machine of the present invention having such a configuration, a plurality of specific game states having different payout rates and total payout numbers can be provided as the specific game state that is the payout reduction time. For example, there is a big bonus (BB) that corresponds to a conventional bonus game with a large amount of payout and there is almost no payout during a specific game, and there is a small amount of payout during a specific game. In addition, two types of ball reduction time can be set: regular bonus (RB), which has less ball loss than big bonuses.
Thus, the player feels expectation, anxiety, and thrill about which ball reduction time is generated, and can provide a more attractive and interesting ball reduction time.

According to the slot machine of the present invention, in a specific game state different from the general game, the number of balls is reduced compared to that in the general game, and the specific game state of the ball reduction mode is terminated when certain conditions are met. By doing so, it is possible to give the player a sense of expectation for large-scale payout and unprecedented surprises, thrills, surprises, and game characteristics that the number of balls is surely reduced.
In particular, the thrill / expectation for the occurrence of a specific gaming state, the shock / impact at the time of occurrence, and the satisfaction / relief at the end of the specific gaming state are completely new game characteristics that do not exist in conventional slot machines. Yes, it can be offered as an attractive slot machine for players.

In addition, the specific game state that becomes the reduction mode of the game can be performed in the same game progress and game system as the conventional jackpot mode, and the player can easily and surely understand the game contents and can be realized immediately. It can be provided as a game machine with excellent versatility and expandability.
Therefore, according to the present invention, it is possible to realize a new slot machine that can provide a sense of expectation, thrill, and satisfaction unprecedented so that players of all levels, from beginners to experts, can enjoy the game. become able to.

It has disappeared.

By the lighting display of this notification lamp, the internal hit is notified together with the notification sound from the speaker 9 described above. That is, when the internal hit notification section 2a is lit, the player can know that the winning flag has been won and the flag has been established as a result of the internal win lottery. It can be seen that when the symbol is stopped at a predetermined winning arrangement (“skull / skull / skull / skull”), a specific gaming state that is the time to decrease the payout starts.
In addition, when a predetermined winning combination is won as a result of an internal winning lottery during a specific gaming state or a general game, this can be notified by lighting on the internal winning notification unit 2a or other lamp indications. . For example, when a winning combination that can end the specific gaming state is won during a specific game, the player is notified by lighting the internal hit notification section 2a, etc. In the game), it can be seen that by stopping the symbol to the predetermined winning arrangement (“Angel / Angel / Angel”), it is possible to end the deduction time, and you can enjoy aiming at the “Angel” symbol, etc. It becomes like this.

Here, the internal hit notification unit 2a can have any configuration as long as the player can visually notify the player of the internal hit, and in addition to the above-described lamp (light-flashing) and translucent display unit, for example, An arbitrary configuration such as a liquid crystal display unit or LEDs arranged in a matrix can be employed.
The notification by the internal hit notification unit 2a can be selectively performed or not performed under the control of the control unit 10. In addition, the target winning combination for which an internal winning notification is made can also set various winning contents such as a jackpot, a general winning combination, an escaped time reduction winning combination, etc. as notification targets.

Each of the credit display unit 2b, the status display unit 2c, and the payout display unit 2d is composed of a 7-segment LED or the like, and displays a predetermined numerical value.
In other words, the credit display unit 2b displays the number of stored medals, the state display unit 2c displays the total number of paid-out medals and the number of digested games in the specific gaming state, and the payout display unit 2d displays the payout at the time of each payout. The number is displayed.
The display unit 2a, the credit display unit 2b, the status display unit 2c, and the payout display unit 2d are driven and controlled by the display drive circuit 16 provided in the control unit 10 (see FIG. 4).

[Control means]
Next, with reference to FIG. 4, the control part 10 which controls the slot machine which concerns on this embodiment which consists of the above structures is demonstrated. FIG. 4 is a block diagram showing an outline of the control means of the slot machine according to the present embodiment.
As shown in the figure, the control unit 10 of the present embodiment is a control means for controlling each part of the slot machine 1 described above, and is constituted by a microcomputer provided with an IC, a memory, various circuit boards and the like. .
Specifically, the control unit 10 includes a CPU 11, a RAM 12 and a ROM 13 that serve as storage means, a clock generation circuit 14 that generates a reference clock, a random number generation circuit 15 that generates random numbers for internal lottery, and display units 2a to 2a. The display unit driving circuit 16 that drives 2d, the sound circuit 17 that generates sound through the speaker 9, the display unit driving circuit 18 that drives the display unit L for presentation, and the like are provided.

First, the control unit 10 inputs a medal signal from the medal selector 6a and a medal signal from the insertion button 7 (7a, 7b), and the number of medals inserted from the medal insertion slot 6 and the insertion button 7 are pressed. While confirming the number of inserted medals bet, the number of stored medals stored in the RAM 12 is decreased based on the medal signal from the insertion button 7. Thereby, the number of medals used (betting) for each game is determined.
Further, the control unit 10 inputs a start signal from the start lever 4 and a stop signal from the stop buttons 5a to 5c, thereby outputting a pulse (driving) signal serving as a control signal for the reel 21 to the drum unit 20, Rotate and stop 21a-21c. Thus, in the drum unit 20, the reels 21a to 21c are rotated by the start signal, and the corresponding reels 21a to 21c are stopped by the stop signal input by pressing the stop buttons 5a to 5c.
Further, the control unit 10 recognizes the stop symbol of each reel 21a to 21c from the marker signal input from the drum unit 20, and determines whether or not the stop symbol is a predetermined winning arrangement. As a result, when the predetermined winning arrangement is selected, the medal payout process according to the type of winning is performed.

And the control part 10 which performs the above game controls performs the lottery per inside for every game, and controls the game according to the result of the lottery per inside.
The internal lottery is a lottery process performed for each game, and is executed by a lottery table preset and stored in the random number generation circuit 15 and the ROM 13 made up of a counter IC or the like. Depending on the region, the content indicated by the region is determined and won as a lottery result.
Specifically, the random number generation circuit 15 generates a random number within a predetermined random width range (for example, 1 to 16384). The lottery table is a data table stored in the ROM 13, and predetermined winning contents are assigned corresponding to a range (1 to 16384, etc.) that can be taken by random numbers.

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

Specifically, the control unit 10 outputs a pulse (drive) signal to the drum unit 20 in order to stop and control the reels 21 in a predetermined winning arrangement according to the result of the internal winning lottery. Based on this, the stop position of the reel 21 is controlled. As a result, the reels 21a to 21c are stopped so that the symbols are arranged in accordance with the winning contents within a certain range, regardless of the timing when the stop buttons 5a to 5c are pressed.
In addition, when the internal winning lottery is won, the control unit 10 outputs a signal to the display unit driving circuit 16 to turn on (flash) the lamp of the internal winning notification unit 2a. Make a hit announcement.

Here, games controlled according to the result of the internal lottery include a general game that is completed for each game and a specific game (a game) that is completed in units of a plurality of games.
In general games, as a result of lottery per internal, stop control such as a small role with a predetermined amount of medals paid out per game, replay (replay) that can play the next game without inserting medals, lose without medal payout, etc. In the game state in which the game is performed, the effect of the result of the general game lottery is effective only for the game, and the effect disappears in the game after the game.

On the other hand, in the case of a specific game (community), when a big win is won as a result of the internal lottery, the specific game state starts when a predetermined condition is established in the game or the next game or later. A game is performed once or a plurality of times under different controls, and when a certain condition is satisfied, the specific gaming state ends.
The basic operation of a game in the slot machine 1 is that a general game is repeatedly performed in units of one game in principle, except for a specific game (a combination) that occurs with a certain probability.

In the present embodiment, the game is controlled such that the payout rate in the specific game state is lower than the payout rate in the general game state.
Specifically, by setting the lottery table used in the internal lottery and the number of payouts at the time of winning to a predetermined value, winning / winning is generated for a winning combination with a large payout in the general gaming state, and a specific game By continuously generating a lost combination without paying out in the state, it is possible to lower the payout rate in the specific game state and to increase the payout rate in the general game state than in the specific game state.

As a result, in the slot machine 1 of the present embodiment, a large amount of payouts are obtained as the general gaming state continues, and the number of acquired medals increases. As a result, when the player enters the specific gaming state, the number of medals earned in the general gaming state decreases.
In other words, the normal game in the normal state becomes more advantageous to the player than the specific game that is a big win, and the player acquires medals as much as possible while in the general game state, and the specific game state is generated. The game is performed so as to end the specific game state as soon as possible when the specific game state is generated / started.

The specific gaming state in which the number of balls is reduced is the same as in the case of the bonus game in the existing slot machine, and is generated by winning a predetermined jackpot as a result of the internal lottery performed for each game (flag is established). In this game or the next and subsequent games, the game will start (win) by being stopped at a predetermined symbol arrangement (“skull / skull / skull / skull”). Start as a gaming state.
And the game state of this ball reduction time is ended by aligning a predetermined stop pattern and stop sequence (one "angel" pattern or "angel / angel / angel" array, etc.), or the conventional mass As in the case of a bonus game with payout, the game ends when the total number of medals paid out in the specific game state reaches a certain number, and as a result, the specific game state continues until the fixed number of games is consumed.

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

[Setting the rate of appearance]
Hereinafter, with reference to FIG. 5, a specific example of setting the payout rate in the slot machine 1 of the present embodiment will be described.
FIG. 5 is a so-called slump curve showing a difference ball situation in a setting example of the following payout rate. FIG. 5A shows the case of the A type in which the payout performance is improved as compared with the conventional slot machine. In the case of the B type in which the difference in the payout rate between the general game and the specific game is large, (c) is the case of the conventional slot machine.
It should be noted that the set value of the payout rate shown below is merely an example, and it goes without saying that other values can be set as long as the payout rate in the specific gaming state is lower than the payout rate in the general gaming state.

[A type]
In this type, the winning contents and probability of internal lottery in general games are set as shown in Table 1 below.

In addition, the winning combination when the winning BB (bonus) with a probability as described above wins a specific gaming state is set as shown in Table 2 below, and the payout in the BB (special prize issue) It is assumed that the BB ends when the total number is 90 sheets.

With the above settings, since the winning probability of BB is 1/100, an average of 100 games will be played in general games before the occurrence of BB, and the payout status during that time is as follows.
-15-game role: 70 games x (15 payout-3 shots) = 840-1-card role: 9 game x (1 payout-3 shots) = -18-Replay: 20 games x (3 photos Payout-3 shots) = 0-BB: 1 game x (0 payout-3 shots) =-3 sheets The total of the difference balls is 819 in total.

After that, when winning a BB and winning (starting) and entering a specific gaming state, the specific gaming state will continue until the total number of payouts (special prizes) in the BB reaches 90.
Since there are only 3 winning combinations in the BB with a probability of 10/100, and there are no other payouts, an average of 300 games will be played before the BB ends with 90 special prizes. The payout status during that time is as follows.
・ 300 games x (-3 cards inserted) + 90 special prizes = -810 cards

From the above, the number of payouts and the number of inputs in the general game state and the specific game state in this type are as follows.
-Payout during general game: (70 games x 15) + (9 games x 1) + (20 games x 3) + (1 game x 0) = 1119 cards-Payout during specific games: Special prizes = 90 games, throwing during general games: 100 games x 3 = 300 cards, throwing during specific games: 300 games x 3 cards = 900

Since the payout rate = (total payout number / total input number) × 100, the general game, the specific game, and the total payout rate are as follows.
・ General game appearance rate = (1119/300) x 100 = 373%
-Specific game appearance rate = (90/900) x 100 = 10%
・ Total payout rate = (1119 + 90 sheets / 300 + 900 sheets) × 100 = 100.75%

The slump curve of this type of difference is as shown in Fig. 5 (a), and a peak of large payouts in general games occurs repeatedly with an average of about 400 games, which is a monotonous suction for players. It is an attractive game with no state, and the total payout rate can be set to about 100%, so that the hall side will be fully profitable.
In addition, in this type, by changing the upper limit value of the 90 special prize balls that end the specific game state, it is possible to vary the payout rate in the specific game, and the game pattern can be changed infinitely. .

[B type]
In this type, the winning contents and probability of the internal lottery in the general game are set as shown in Table 3 below.

In addition, the winning combination when the winning BB (bonus) with the probability as described above wins a specific gaming state is set as shown in Table 4 below, and the payout in the BB (special prizes) The total number is 1, that is, when the symbols “angel, angel, angel” are arranged in the BB, one is paid out, and the BB ends.

With the above settings, since the winning probability of BB is 1/200, an average of 200 games will be played in general games before the occurrence of BB, and the payout status during that time is as follows.
-15-game: 176 games x (15 payout-3 shots) = 2112-Replay: 23 games x (3 payouts-3 inserts) = 0-BB: 1 game x (0 payouts-3 The total number of difference balls over 3 sheets is 2109.

After that, when BB is won and won (started), it becomes a specific game state. Until there is one payout (special prize ball) in the BB, that is, the specific game state until "Angel / Angel / Angel" is complete Will continue.
Since only one winning combination is set at a probability of 1/700 in BB and there is no other payout, 700 games will be played on average before the end of the BB. It becomes like this.
-700 games x (-3 shots) + 1 special prizes = -2099

From the above, the number of payouts and the number of inputs in the general game state and the specific game state in this type are as follows.
-Payout during general game: (176 games x 15) + (23 games x 3) + (1 game x 0) = 2709-Payout during specific game: 1 special prize ball = 1 200 games x 3 = 600-Input during specific game: 700 games x 3 = 2100

In this type, the general game, the specific game, and the total payout rate are as follows.
-General game appearance rate = (2709/600) x 100 = 451.5%
-Specific game appearance rate = (1/2100) x 100 = 0.048%
-Total payout rate = (2709 + 1/600 + 2100) x 100 = 100.37%

The slump curve of this type of difference is as shown in FIG. 5 (b), where a large amount of 2000 or more is paid out in a short period of about 200 games average, and then a long suction state is reached. Therefore, it becomes an attractive game for a player to expect a large amount of payout before the specific game state occurs, and even when entering the specific game state, only one “angel” symbol is arranged. If the payout is obtained, the specific game is completed, so there is an interest that the feeling of expectation for the game “angel” is increased even during the specific game.
Further, even in this type of setting, the total payout rate is about 100%, similar to the large payout type shown in FIG. 5 (a), so that the hall side is sufficiently profitable.
Also in this type, by changing the winning probability of the “angel” symbol that ends the specific game state, the play rate in the specific game can be varied, and the game pattern can be changed infinitely.

On the other hand, in the case of the conventional slot machine, for example, the situation as shown in FIG.
As shown in the figure, in the conventional slot machine, the number of balls is basically reduced in the general gaming state until a specific gaming state (bonus game) with a large amount of payout due to the jackpot occurs. And the difference ball will increase only when it is a big hit, but generally it will be a monotonous and less undulating and sharp difference situation, compared to the case of this embodiment for the player It is easy to become a less attractive game.

In the two setting examples of the present embodiment described above, only one type (BB) is shown as the specific game state starting with the jackpot, but as the specific game state that becomes the payout reduction time, A plurality of specific game states having different total payout numbers can be provided. For example, there are two types of settings corresponding to the conventional big hit (bonus game) with a large amount of payout, that is, a big bonus (BB) where there is almost no payout during a specific game, and a specific game There are two types of payout reduction time, regular bonus (RB), in which there is a small amount of payout in a predetermined amount and there is less decrease in the payout than the big bonus.
In this way, the player will also feel the expectation, anxiety, and thrill of which ball reduction time will occur, and will be able to provide a more attractive and interesting ball reduction time. .

[Game operation]
Next, the gaming operation of the slot machine according to the present embodiment as described above will be described with reference to FIG.
FIG. 6 is a flowchart showing an outline of the gaming operation of the slot machine according to the present embodiment.
First, the game is started when the player inserts a medal into the medal slot 6 (step 601 in FIG. 6). The game started at this time is a game in a general gaming state.
Here, the medals to be inserted are usually assigned to one bet, two bets or three bets corresponding to the pay line on the display window 3, and when four or more medals are inserted, four medals are inserted. The above medals are stored in the RAM 12 of the control unit 10 as stored medals. Therefore, the stored medal is used for the second and subsequent games by the insertion button 7.

After the medal is inserted, the start lever 4 is pressed (step 602), the three reels 21 start rotating, and at the same time, the control unit 10 performs a lottery for the inside (step 603).
Here, as a result of the internal winning lottery, if a predetermined big win (BB) has been won, at the same time as the start of the game or after the end of the game, the predetermined internal winning is made via the internal winning notification unit 2a. Announcement is made.

Thereafter, when the player presses the stop buttons 5a to 5c (step 604), the reels 21a to 21c corresponding to the stop buttons 5a to 5c are controlled to stop (step 605).
At this time, the reels 21a to 21c are controlled by the control unit 10 and the drum unit 20 so that the symbols on the reels are in accordance with the prize winning content of the lottery within a certain range regardless of the timing of pressing the stop button 5. The stop control is performed so that the predetermined arrangement is obtained.

When all the reels 21a to 21c are stopped (step 605), processing corresponding to the stopped symbols is performed.
First, as a result of the internal lottery (step 603), when the big win is not won (No in step 606), if the player is in a general gaming state and has won a predetermined number of payouts ( On the condition that the reel stop symbol is in a predetermined winning arrangement (step 608), medals corresponding to the winning arrangement are paid out (step 609).
In this embodiment, it is set to win a general small role that has a high probability of paying out in the general gaming state, and the player can aim for winning and paying out as much as possible by shooting and aiming for a predetermined winning arrangement. A general small role can be arranged, and a large amount of payout can be obtained.
Thereafter, the continuation or end of the game is selected according to the player's judgment (step 610).

On the other hand, as a result of the internal winning lottery (step 603), when the big win is won (Yes in step 606), the flag is established, and the stop symbol of the reel 21 has a predetermined winning arrangement (“skull / skull / skull / draw”). ”), The game is won (Yes in Step 611), and the specified game state is entered, and the payout reduction time starts (Step 612).
If the stop symbol is not in the predetermined winning arrangement (“skull / skull / skull”) (No in step 611), the payout reduction time will not start, and it will be elected as a general small role according to the stopped symbol array If so (Yes in Step 607), the medals corresponding to the winning arrangement will be paid out (Step 609) on condition that the reel stop symbols are in a predetermined winning arrangement (Step 608). .
At this time, since the player can know that the flag has been established by the lighting display of the internal hit notification section 2a, until a predetermined winning arrangement ("skull / skull / skull") is complete and the big win starts, Players will be able to enjoy games aimed at general payouts with payouts while avoiding the stop symbol where the ball reduction time starts as much as possible. You can also enjoy the thrill of "Do not do it!" And "Don't pull the skull!"

When the winning arrangements are aligned and the payout reduction time starts (Yes in step 607), as described above, the total number of payouts during the specific game reaches a predetermined number, or the stop symbols of the reels 21 are in a predetermined arrangement (“angel” The game will not end unless it becomes “Angel / Angel”), and during that time, the rate of appearance will be controlled lower than in general games, and as a result, the number of players will be reduced.
Thereafter, when the total number of payouts during the specific game reaches a predetermined number, or when the stop symbols of the reels 21 are in a predetermined arrangement, the specific game state is ended and the general game state is restored.
Therefore, during a specific gaming state, the player will play the game aiming at the “angel” symbol, and when the “angel” is drawn, the player will be able to enjoy the satisfaction, relief, etc. Become. At this time, when the “angel” role is won as a result of the internal winning lottery, it can be notified by turning on the internal winning notification section 2a, etc., and the player can enjoy aiming at the “angel” symbol.
Thereafter, the continuation or end of the game is selected according to the player's judgment (step 610).

As described above, according to the slot machine according to the present embodiment, the general gaming state and the specific gaming state are controlled by the control of the control unit in the slot machine. In the specific game state that occurs, the game is controlled so that the payout rate is lower than that in the general game state.
As a result, when the general gaming state continues, a large amount of payouts are obtained and the number of acquired medals increases, and when the big game hits the specific gaming state, the number of balls played is less than the general gaming state, and as a result When entering the state, medals won in the general gaming state will decrease.

Therefore, in this embodiment, the player can continuously play a game advantageous in general games and receive a medal payout, and when a specific game state occurs when a big win is drawn as a result of the internal lottery, Will be reduced, and even players with weak pulling will be able to fully enjoy the advantageous game state in general games. On the other hand, it is possible to enjoy an unprecedented game and game characteristics, such as winning a large amount of payouts by arranging winning symbols as much as possible in general games.
As described above, according to the slot machine of this embodiment, regardless of the level or skill of a player such as a beginner or an advanced player, any player can enjoy an advantageous game in general games, and the thrill of a specific game can be achieved. You can enjoy surprises, surprises, and satisfaction and relief at the end of a particular gaming state.

For the player, the thrill of the big hits, where the number of balls that are not known when it is reduced, and the satisfaction and accomplishment of the favorable ball status in the general gaming state in the meantime, are increased, and the jackpots with a certain probability This will give you a surprise shock when you experience the problem, and a sense of relief and satisfaction when it ends, and you can realize an attractive slot machine with unexpected and high satisfaction with thrilling that has never existed before.
In addition, jackpots with fewer balls than regular games are less likely to be targets of fraud, and general games that are completed in units of one game are cumbersome and difficult to shoot with bodily sensation devices. Therefore, as a result, illegal acts such as bodily sensations can hardly be performed, and a highly safe gaming machine can be realized.

The slot machine of the present invention has been described with reference to the preferred embodiment. However, the slot machine according to the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. It goes without saying that it is possible.
For example, in the above-described embodiment, the case where two types of play reduction times with different payout rates are set as the specific game state is shown. However, a specific game state with a low play rate has a different play rate. Of course, it is possible to set more than one mode.

  In addition, the prizes that are drawn and determined by lottery inside the slot machine are generally divided into several types, such as “losing”, “small role (including replay)”, and “big winning (BB, RB)”. In the present invention, the same winning contents are determined by lottery, but the type and specific contents of the winning are set according to the type and type of the slot machine. Even in the present invention, as long as the payout rate in the specific gaming state is set lower than the payout rate in the general gaming state, there is no particular limitation on the type and content of the winning.

  Further, as long as the game play rate in the specific game state is set lower than the game play rate in the general game state, in the general game state, it is possible to perform control that is advantageous to the player as in the existing slot machine. For example, by notifying the player of the stop order and timing of the reels, when a stop button is pressed in the stop order or timing, a predetermined winning arrangement is always obtained, so-called assist time (AT) or medal Replays that can be played in the next game without throwing in are highly probable so that the consumption of medals can be reduced, so-called replay time (RT), reels at the timing when the player performs a stop operation for some or all reels Is known, so-called challenge time (CT), which is advantageous to advanced players who can accurately perform the reel stop operation, is also known in the general gaming state of the slot machine according to the present invention. Various types of control can be performed.

  Furthermore, in the slot machine of the above-described embodiment, the case where the game medium to be used is a medal (coin) is shown, but the game medium that can be used in the slot machine according to the present invention is not limited to a medal, for example, a pachinko ball and the like Similar game balls can also be used as game media. A slot machine that can be played using such a game ball is also called a pachilot or the like, and can be applied as a slot machine of the present invention having a reduced play time.

  INDUSTRIAL APPLICABILITY The present invention can be used for a slot machine (revolving game machine) in which a game is mainly performed using medals (coins) as game media, and in particular, one game according to a lottery result for each game. The present invention can be suitably used for a slot machine having a general gaming state completed in units and a specific gaming state completed in units of a plurality of games.
