It is an object of the present invention to provide a gaming machine which can change the probability of winning determination without providing a plurality of game machines.

(Claims 5 to 16) The inventions of claims 5 to 16 have the following objects in addition to the objects of the inventions of claims 1 to 4 described above. That is, an object of the present invention is to provide a gaming machine capable of increasing or decreasing the probability of winning determination during a game.

[0006]

Means for Solving the Problems (Features) The inventions described in the respective claims are made to achieve the above objects, and the features of the inventions are shown in the drawings. This will be described below using embodiments of the present invention.

[0007] The reference numerals indicate the reference numerals used in the embodiments of the present invention, and do not limit the technical scope of the present invention. (Claim 1) The invention according to claim 1 has the following features. That is, the invention according to claim 1 includes the rotating reel 40 having a plurality of symbols 61 displayed on the surface thereof.
A game machine including a control device 20 for controlling rotation and stop of the game and performing a lottery of a prize with a predetermined probability using a random number, wherein the acquired random number and various prize forms are set within the range of the random number. The lottery winning is determined by comparing the specified winning determination table 113, and a stop control corresponding to the lottery result is performed, and a plurality of symbols 61 displayed on the front side with the plurality of rotating reels 40 stopped. Is displayed in a predetermined position mode, in the gaming machine in which a prize is determined, as the stop control, a stop control for pulling in a winning symbol with a predetermined probability (hereinafter referred to as a pull-in control) and a stop control for not pulling in a winning symbol. Stop control (hereinafter referred to as kick-off control) is provided, and the stop control for pulling in the winning symbol includes a control for pulling in a winning symbol with a high probability (hereinafter, high-probability pull-in control). ) And a control for pulling in a winning symbol with a low probability (hereinafter referred to as a low probability pulling control). A control for pulling in a winning symbol with a high probability and a control for pulling in a winning symbol with a low probability. A stop control selecting unit 122 for selecting which of the controls to perform is provided, and depending on which stop control is performed based on the selection result of the stop control selecting unit 122, the probability of winning determination varies as a result. It is characterized by being formed as described above.

According to the present invention, there is provided a gaming machine in which a prize is determined by lottery using a probability table, and the prize is determined when the symbols displayed on the plurality of rotating reels are arranged in a predetermined position mode, for example, on a predetermined line. For example, it is suitable for slot machines. Here, "lottery prize" means winning in a prize lottery, and "winning decision" means a state in which pull-in and kick-out described later are set based on the lottery prize. That is, in the present invention, the lottery win is positioned as a temporary win, and the original win is determined by the winning determination. "Confirmation of winning" means that after winning, each rotating reel 40 stops so as to arrange a predetermined symbol (winning symbol) representing a predetermined winning at a predetermined position.

The pull-in control means that each of the reels 40
Is performed to stop the rotating reel 40 in order to arrange the symbols displayed in the position in a predetermined winning position as much as possible. Specifically, at a predetermined time that triggers the stoppage of the rotating reel (for example, when a stop switch is operated in the case of a slot machine), a symbol at a predetermined position is set as a reference symbol, and the reel 40 is rotated from the reference symbol to a predetermined number of frames. Is rotated to stop. Whether or not a winning symbol can be drawn depends on whether or not there is a winning symbol within a predetermined number of frames from the reference symbol, and the pull-in probability differs depending on the number of frames that can be drawn in the control. For example, the pull-in probability becomes higher when the setting is made so that only five frames can be drawn from the reference symbol than when only one frame is drawn from the reference symbol.

[0010] On the other hand, the kicking-off control means that each rotating reel 40
Is controlled to stop the rotating reel 40 so as not to arrange the symbols displayed in the predetermined winning position mode. When the lottery result based on the winning determination table 113 is a predetermined winning combination winning, the stop control selecting means 122 selects and determines which control among the above-described pull-in controls is used to stop the rotating reel 40. It is. The selection method may be by lottery or may be based on the presence or absence of a specific condition. In addition, the above determination may be made for each winning, or may be performed only during a specific period.

(Operation) Based on the determination of the stop control selecting means 122, the control device 20 performs stop control of the rotating reel 40. At this time, even if the winning is the same, when the stop control selecting means 122 selects the low probability pull-in control, the winning symbol is positioned at a predetermined position as compared with the case where the control for pulling in the winning symbol with a normal probability is performed. Since it is unlikely to be the mode, the probability of winning determination is reduced as a result. On the other hand, when the high-probability pull-in control is selected, the probability of the winning determination becomes higher.

As described above, depending on which stop control is selected by the stop control selecting means 122, the probability of winning determination can be changed without changing the lottery probability of the winning determination table 113, and as a result, the winning is determined. It is possible to change the opportunities that can be taken. (Claim 2) The invention according to claim 2 has the following features.

That is, the invention according to claim 2 has a rotating reel 40 on which a plurality of symbols 61 are displayed on the surface, controls the rotation and stop of the rotating reel 40, and wins at a predetermined probability using random numbers. Is a gaming machine including a control device 20 for performing a lottery, and determines a lottery winning by comparing the obtained random number with a winning determination table 113 that defines various winning modes within the range of the random number. At the same time, a gaming machine that performs stop control corresponding to the lottery result, and a plurality of symbols 61 displayed on the front side are displayed in a predetermined position mode in a state where the plurality of rotating reels 40 are stopped, whereby a winning is determined. In the stop control, a stop control for drawing in a winning symbol with a predetermined probability and a control for not pulling in a winning symbol are provided, and the stop control for pulling in the winning symbol is provided with a high probability. The control includes a control for pulling in a symbol and a control for pulling in a winning symbol with a low probability, and a stop control selecting unit 122 for selecting which of the stop controls is to be provided. It is characterized in that the probability of winning determination is changed as a result depending on which stop control is performed based on the selection result of the selection means 122.

In the present invention, the stop control selecting means 122
In the case where the lottery result based on the winning determination table 113 is a predetermined winning combination winning, a control is selected to determine which of the pull-in control and the kicking-off control is used to stop the rotating reel 40. Therefore, even in the case of a prize, if the stop control selecting means 122 selects the kicking control, the prize is not determined.

The selection method by the stop control selecting means 122 may be by lottery or may be based on the presence or absence of a specific condition. In addition, the above determination may be made for each winning, or may be performed only during a specific period. (Operation) According to the present invention, even if the winning is the same, when the stop control selecting means 122 selects the low probability pull-in control, compared to the case where the control for pulling in the winning symbol with a normal probability is performed, Since the winning symbol rarely has a predetermined position mode, the probability of winning determination is low as a result. On the other hand, when the high-probability pull-in control is selected, the probability of the winning determination becomes higher. Further, when the kick control is selected, the winning is not determined.

As described above, depending on which stop control is selected by the stop control selecting means 122, the probability of winning determination can be changed without changing the lottery probability of the winning determination table 113, and as a result, the winning is determined. It is possible to change the opportunities that can be taken.

At the time of "Replay", when the start switch 30 is operated on condition that a predetermined time has elapsed from the previous game, the reel unit 60 is driven, and the three rotating reels 40 start rotating.

Thereafter, when one of the stop switches 50 is operated, the rotation of the corresponding rotary reel 40 stops.
When all three stop switches 50 have been operated, the rotation of all three rotating reels 40 stops. At this time, when the predetermined symbol 61 stops on the activated pay line of the display window 12, a predetermined number of medals are paid out via the hopper unit 65. Instead of paying out medals, credits may be given.

Winning involves paying out game medals,
There is no small medal prize that gives the player a profit, a special prize that gives the player even greater profits than this small prize prize, and there is no payout of game medals, but again without inserting new game medals "Replay" that can be played. If the lottery result is one of the winnings, a winning flag corresponding to the winning is established. Then, when the lottery result is a special winning, a special winning flag is established. During the special winning flag is established, the stop symbol of the rotating reel 40 of the reel unit 60 is stopped.
61 combinations are predetermined special winning symbols
The winning is determined on condition that it matches 61 (for example, three "7" s are on the activated pay line), and the player is made to play an advantageous special game. on the other hand,
The special winning flag was established by lottery, but the reel 40
If the combination of the stop symbols 61 does not match the special prize symbol 61, the right to establish the special prize flag is carried over to the subsequent games. If the winning flag of the small role cannot determine the winning in the game for which the winning flag has been established, the right of the winning flag establishment does not carry over to the next game.

While any of the winning flags is established,
Whether or not the corresponding winning symbols 61 can be aligned on the activated pay line depends on the timing of the stop switch 50 when the rotation speed of the rotating reel 40 is constant. The stop of the rotating reel 40 is controlled by a reel rotation stop control means 120 described later, and a stop symbol is determined based on a stop table 121 provided for each symbol. Each stop table is a symbol that can be stopped at the time of operating the stop switch 50, is a reference symbol, and determines how many frames are moved from the reference symbol to stop the rotating reel, and a winning is won. In this case, if the stop switch 50 is operated within the range of the number of movable frames, the symbol is drawn in and the reel 40 is stopped. However, if there is no winning symbol within the range of the number of movable frames, the symbol cannot be pulled in to stop the rotating reel 40.

(Special game control means 80) Special game control means
80 is for causing the player to perform an advantageous special game based on the lottery result of the lottery means. The above special games are roughly classified into the following games. (1) Specific introduction game (BB game) (2) Specific game (RB game) (3) Specific winning game (JAC game) Note that a specific game, for example, an RB game is a specific introduction game.
For example, there is a case where the game is performed during the BB game and a case where the game is performed alone when the game is not being performed. Further, the above-mentioned specific winning game, that is, a so-called JAC game, is performed during the RB game. Further, the special game is not limited to the above-mentioned games (1) to (3).

As shown in FIG. 1, the special game control means 80 is roughly provided with the following means. (1) Specific introduction game control means 91 (BB game control means 9
0) (2) Specific game control means 101 (RB game control means 100) (Specific introduction game control means 91) Specific introduction game control means 91
Is for controlling the BB game.

More specifically, in the normal game, although not shown, for example, when three symbols 61 such as “7” are arranged on the activated pay line, for example, 15 medals are paid out via the hopper unit 65. . At this time, the BB game is started. When the game shifts to the BB game, the game is started by inserting up to three medals as in the normal game, and when the rotation of each of the three spinning reels is stopped, it is determined whether or not the winning symbols are aligned on the activated pay line. Payout of medals.

Therefore, in the BB game, a lottery including a small combination is performed every time as in the normal game.
However, if the specific winning symbols for shifting to the RB game during the BB game are aligned on the activated pay line, then the process shifts to the RB game. Usually, B
During the B game, the transition to the RB game is supposed to be performed, for example, up to three times. Therefore, after the first RB game is completed, the lottery and control similar to the normal game described above are performed again. Is what is done.

In the BB game, the number of RB games in the BB game is a predetermined maximum number of times, for example, three times, or
A predetermined maximum number of regular games during the B game, for example, a maximum of 3
The BB game ends when the game has ended 0 times. (Specific game control means 101) The specific game control means 101
It is for controlling the game.

Specifically, when the game shifts to the RB game, one medal is inserted, and when the predetermined symbol 61 of the rotating reel 40 is aligned with the center line of the display window 12, a specific winning game is determined. Is what is done. And RB
In the game, a maximum of 12 specific prize games to determine whether or not to win
The winning can be confirmed up to eight times. That is, up to eight winnings are confirmed,
Alternatively, the RB game ends when the maximum of 12 specific winning games have ended.

(Winning lottery means 110) The winning lottery means 110
A lottery for a prize determination as to whether or not a prize is made is performed based on a predetermined lottery probability. Then, when the lottery result by the prize lottery means 110 is a prize, a prize flag is established, and during the prize flag is established, the combination of the stop symbols of the rotating reel 40 matches a predetermined prize symbol. The winning is determined, and the player is provided with a medal payout or a special game.

As shown in FIG. 1, the winning lottery means 110 is roughly divided into the following means. (1) random number generating means 111 (2) random number extracting means 112 (3) winning determination table 113 (4) determining means 114 The winning lottery means 110 is limited to the above (1) to (4) is not.

(Random number generating means 111)
A random number for a winning lottery is set in a predetermined area (for example, 0 to 10 in decimal).
65535). (Random number extracting means 112) The random number extracting means 112 is a random number generating means.
The random number generated by 111 is extracted under a predetermined condition (for example, operation of the start switch 30). The extracted random numbers are used as extracted random number data.

Here, the "random number generating means"
In addition to a random number that can be generated by the average sampling method as a soft random number, a counter that adds a fixed range of numbers one by one at a high speed can also be used. For example, a counter in which a number in the range of 0 to 16383 is sequentially repeated about 7 million times per second can be considered.
Then, the "random number extracting means" reads the number of the counter when the start switch is pressed.

When formed as described above, the "random number generating means"
Although the random numbers are not generated, the numbers extracted by the "random number extracting means" have a distribution like random numbers. As described above, means for obtaining a number indicating a distribution like a random number as a result is considered here as being included in “random number generating means” or “random number extracting means”.

(Winning Determination Table 113) The winning determination table 113 has a winning area of each winning item in the whole area of the random numbers taken by the random number generating means 111. Note that the probability of winning is determined by the reel rotation stop control means 120 described later.
The winning probability of 3 can be set higher or lower than the general probability.

(Determining Unit 114) Based on the extracted random number data extracted by the random number extracting unit 112 and the lottery probability data of the winning determination table 113, the determining unit 114 determines each of the random numbers in the entire area of the random number generated by the random number generating unit 111. This is to collate with the prize determination area data including the prize area of the prize item, and determine a prize corresponding to the prize area to which the extracted random number data belongs.

(Reel rotation stop control means 120) The reel rotation stop control means 120 is for performing control to stop the rotating reel 40 at a predetermined position based on the lottery result of the winning lottery means 110. Reel rotation stop control means 120
As shown in FIG. 1, the device is roughly provided with the following means.

(1) Stop table 121 (2) Stop control selection means 122 (3) Stop position determination means 123 (4) Stop position output means 124 The reel rotation stop control means 120 includes the above (1) to ( The present invention is not limited to the means of 4), and may have other means.

(Stop Table 121) The stop table 121
A symbol that can be stopped when the stop switch 50 is operated is set as a reference symbol, and how many symbols are moved from the reference symbol and the rotating reel is stopped is defined for each symbol according to the presence or absence of a prize. . Specifically, the stop table 121 includes a plurality of winning symbol stop tables for pulling in and stopping the winning symbols with different probabilities, and a losing stop table for kicking and stopping the winning symbols. It is provided for each symbol. Further, the winning symbol stop table includes a winning advantageous stop table for performing control for drawing a winning symbol with a high probability and a winning disadvantage stopping table for performing control for pulling a winning symbol with a low probability. A table other than these (for example, a table for pulling in a winning symbol with a probability between a winning stoppage table and a disadvantage stop table) may be included.

The pull-in probability of the winning symbol stop table differs depending on how many frames from the reference symbol can be pulled in and stopped. The losing stop table is set so that none of the winning symbols stops at a predetermined position. (Stop control selecting means 122) The stop control selecting means 122 controls the above-described stop table 12 in accordance with the result of the winning lottery or whether the gaming state satisfies a specific condition.
By selecting 1, the stop control is determined. Regarding the operation of the stop control selecting means 122,
Since various forms are possible, these forms will be described below.

(First Mode) In the first mode, the stop table 121 is selected by lottery in accordance with the winning lottery result (see FIGS. 5 and 6). That is, when the winning lottery result is a loss, the stop control selecting means 122 unconditionally acquires the loss stop table. On the other hand, when the lottery result is a predetermined prize, one stop table is selected by lottery from among a plurality of prize symbol stop tables corresponding to the prize symbols of the winning combination, and the stop control is performed using any of the tables. Decide what to do. This lottery is performed using a lottery table that defines the area of each winning symbol stop table. The ratio of the area of each winning symbol stop table is determined by the lottery probability of the winning determination table 113 and the probability that the winning can be determined as a result. The setting is determined according to the degree of the setting.

When a winning winning stop table is obtained as a result of the lottery of the stop table 121, winning is easily determined, and as a result, the probability of winning determination becomes high. When a winning disadvantage stopping table is obtained, However, winning is difficult to determine, and as a result, the probability of winning determination is low. The lottery of the stop table 121 may be performed including the loss stop table. If the losing stop table is acquired, the prize will not be determined.

(Second Mode) In a second mode, the stop table 121 is selected in accordance with whether or not a winning lottery result and a gaming state satisfy specific conditions. A winning advantage stop table or a winning disadvantage stop table is selected (see FIG. 7).

That is, when the lottery result of the winning is a loss, the stop control selecting means 122 unconditionally acquires the loss stop table. On the other hand, if the lottery result is a predetermined prize, it is determined whether or not the gaming state satisfies a specific condition, and if the gaming state satisfies a specific condition, the winning advantage is unconditionally determined. Select a stop table. Conversely, when the gaming state does not satisfy a specific condition, that is, during a general game, the winning disadvantage stop table is unconditionally selected. For this reason, when a specific condition is met, winning is more easily determined than during a general game, and as a result, the probability of winning determination is increased.

Further, the stop control selecting means 122 can unconditionally select the winning disadvantage stop table when the gaming state satisfies a specific condition.
In this case, during a general game, the winning advantage stop table is obtained unconditionally. In this manner, contrary to the above-described case, when the gaming state satisfies a specific condition, winning determination is reduced, and as a result, the probability of winning determination is reduced.

(Third Mode) In a third mode, the stop table 121 is randomly selected and selected according to whether or not a winning lottery result and a gaming state satisfy specific conditions. When a specific condition is met, a winning advantage stop table is selected (see FIGS. 8 and 9).

That is, when the winning lottery result is a loss, the stop control selecting means 122 unconditionally acquires the loss stop table. On the other hand, if the lottery result is a predetermined prize, it is determined whether or not the gaming state satisfies a specific condition, and if the gaming state satisfies a specific condition, the winning advantage is unconditionally determined. Select a stop table. Conversely, if the game state does not satisfy a specific condition, that is, if a general game is being played, a plurality of stop tables 121 are provided.
One of the stop tables 121 is selected by lottery from among them, and it is determined which is used to perform the stop control.

The stop table 121 symmetrical to the lottery performed here can be a winning disadvantage stop table and a loss stop table, or can be a winning stop table, a disadvantage stop table and a loss stop table. . By performing such a lottery, it is easier to determine the winning when the specific condition is satisfied, as compared to during a general game, and as a result, the probability of the winning determination is increased.

(Fourth Mode) In a fourth mode, the stop table 121 is selected by lottery in accordance with the result of a winning lottery and whether the gaming state satisfies a specific condition. When a specific condition is satisfied, a winning disadvantage stop table is selected (see FIG. 10). That is,
If the winning lottery result is a loss, the stop control selecting means 122 acquires the loss stop table unconditionally. On the other hand, if the lottery result is a predetermined prize, it is determined whether or not the gaming state satisfies a specific condition, and if the gaming state satisfies a specific condition, the prize is unconditionally disadvantaged. Select a stop table. Conversely, when the game state does not satisfy a specific condition, that is, during a general game, one stop table 121 is selected by lottery from among the plurality of stop tables 121, and the stop control is performed using any one of them. Decide what to do.

The stop table 121 symmetrical to the lottery performed here is a stop table other than the prize winning stop table and the prize stop table (for example, a stop table with a pull-in probability between the prize stop table and the prize stop table). Or a winning advantage stop table and a winning disadvantage stop table. And, by performing such a lottery, it becomes more difficult to determine a winning when specific conditions are met, compared to during a general game,
As a result, the probability of winning determination is reduced.

(Fifth Mode) In a fifth mode, the stop table 121 is randomly selected and selected according to whether or not a winning lottery result and a gaming state satisfy specific conditions. When a specific condition is satisfied, the probability of selecting the winning advantage stop table or the winning disadvantage stop table is increased (see FIG. 11).

That is, when the lottery result of the winning is a loss, the stop control selecting means 122 acquires the loss stop table unconditionally. On the other hand, when the lottery result is a predetermined winning, it is determined whether or not the gaming state satisfies a specific condition. When the gaming state satisfies a specific condition, one stop table 121 is selected from a plurality of stop tables 121 using a lottery table having a high winning probability of a winning advantage stop table, and any one of the stop tables is used to stop. Decide whether to perform control. On the other hand, when the gaming state does not satisfy a specific condition, that is, during a general game, a lottery table with a low winning probability of a winning advantage stop table (a lottery table with a high winning probability of a winning disadvantage stop table or a loss stop table). Is used to select one stop table 121 from the plurality of stop tables 121, and it is determined which one to use for the stop control.

The stop table 121 symmetrical to the lottery performed here may be a winning stop table and a disadvantage stop table, or may be a winning stop table, a disadvantage stop table and a loss stop table. it can. By performing such a lottery, it is easier to determine the winning when the specific condition is satisfied, as compared to during a general game, and as a result, the probability of the winning determination is increased.

Further, when the gaming state satisfies a specific condition, the stop control selecting means 122 uses a lottery table with a high winning probability of a winning non-performance stop table or a loss stop table to generate a plurality of stop tables 121. It is also possible to select one stop table 121 from among them and determine which to use to perform the stop control. In this case, at the time of a general game, a lottery is performed using a lottery table having a high winning probability of the winning advantage stop table.
In this manner, contrary to the above-described case, when the gaming state satisfies a specific condition, winning determination is reduced, and as a result, the probability of winning determination is reduced.

By the way, the "case where the gaming state satisfies a specific condition" in the above-described second to fifth embodiments may be as follows. (1) When the total value of the payout medals becomes equal to or less than a certain value or equal to or more than a certain value. The slot machine 10 is provided with a difference counter for counting the difference between the number of inserted medals and the number of paid medals,
When the value of the difference counter becomes equal to or less than a certain value, the winning advantage stop table is selected (or is easily selected). As a result, the winning determination is increased, and the payout medals are also increased.

Alternatively, when the value of the difference counter becomes equal to or more than a predetermined value, the winning disadvantage stop table is selected (or is easily selected). As a result, the winning determination decreases, and the payout medals decrease. (2) During a normal game during a BB game. For example, during a normal game, even if a small winning combination wins, the stop control is removed so that the probability of a general winning determination is lower. In the normal game during the BB game, by increasing the probability of the winning determination as a result, the winning of the small role increases, and once the BB game is won, a large number of medals can be obtained. it can.

(3) After the end of the BB game. During normal play, even if the small role wins, remove the stop control,
Make it the probability of a general winning decision. And B
By selecting (or making it easier to select) the winning advantage stop table during a certain period after the end of the B game, the winning of the small role increases, and the chance game of the connection to the next BB game is realized. be able to. The fixed period may be, for example, until a predetermined number of games are completed, a predetermined number of medals are paid out, or the like.

Conversely, during a certain period after the end of the BB game, the winning combination of the small role may be reduced by selecting (or making it easier to select) the winning disadvantage stop table. In this case, an advanced person with a good skill in pushing can stop the winning symbol at a predetermined position even if the stop control has a low pull-in probability, so that the medal difference between the advanced person and the beginner is small. growing. In other words, a certain winning symbol can be positioned as a game replacing the challenge time game in which the stop control is not partially performed.

Further, it may be determined whether the probability of winning determination is to be higher or lower as a result of the number of medals paid out during the BB game. (4) The specific flag is being established. During a normal game, even if a BB game or RB game is won, the stop control is removed and the lottery probability of the winning symbol stop table is adjusted so as to be lower than the probability of a general winning determination. Then, when the BB flag and the RB flag are established, the winning advantage stop table is selected (or made to be easily selected), so that once the BB and RB are won, the winning can be determined with a considerable probability. can do.

(5) Determined by lottery. The lottery is performed during the game, and the fact that the lottery has been won is defined as “specific conditions”. The lottery may be performed at any time during the normal game, or may be performed at the time of BB winning or at the end of BB. The above (2) to (4) may also be determined by this lottery.

(Stop position determining means 123) The stop position determining means 123 is for determining the stop position of the symbol using a predetermined stop table based on the determination by the stop control selecting means 122. In other words, the symbol of the rotating reel that can be immediately stopped at a predetermined position when the stop switch 50 is pressed is used as a reference symbol, and within the range from the reference symbol to the symbol at the time of moving a predetermined number of frames in the rotating direction, where to stop. decide.

The stop table may be created on the assumption that the stop switch 50 is operated at all positions for each symbol. However, since all combinations must be created for each symbol, the number of tables is limited. Becomes huge. Therefore, a stop position candidate may be determined according to the stop table, and the stop symbol may be determined while determining the validity of the candidate. Specifically, a bit corresponding to a winning symbol is provided separately for a winning symbol to be stopped and a symbol that must not be stopped, and a stop position candidate is appropriate based on data stored in the bit. Is stopped at that position, and if it is not appropriate, another valid position is determined and stopped.

(Stop position output means 124) The stop position output means 124 is for transmitting data of the stop position determined by the stop position determining means 123 to the reel unit 60. The reel unit 60 stops the rotating reel 40 at a predetermined position based on the stop position data. (Operation of Slot Machine 10) Next, an outline of the operation of the slot machine having the above configuration will be described with reference to the flow charts shown in FIGS.

First, in step 100 shown in FIG. 3, the start switch 30 is turned on by operating the start switch 30. And the next step 1
Go to 01. In step 101, the winning lottery means 11
With 0, a lottery process is performed. And the next step 1
Go to 02.

In step 102, the rotation of the rotating reel 40 starts. Then, the process proceeds to the next step 103.
In step 103, the stop switch 50 is turned on by operating the stop switch 50. Then, the process proceeds to the next step 104. In step 104, the rotation stop processing of the rotating reel 40 is performed. Then, the process proceeds to the next step 105.

In step 105, it is determined whether or not the stop switch 50 corresponding to the three reels 40 has been operated. When it is determined that the stop switch 50 corresponding to the three rotating reels 40 has been operated, the process proceeds to the next step 106. In step 106, it is determined whether or not the winning symbols corresponding to the winning flag are aligned on the activated winning line while the winning flag is established, that is,
It is determined whether or not the winning is determined. Then, when it is determined that the winning is determined, the process proceeds to the next step 107.

At step 107, a medal corresponding to a winning symbol is paid out. Then, the game ends.
If it is determined in step 105 that the stop switch 50 corresponding to the three rotating reels 40 has not been operated, the process returns to step 103. Step 1
If it is determined in 06 that the winning has not been determined, step 107 is skipped and the game ends.

The lottery process in step 101 will be described with reference to the flowchart of FIG. In step 200, a random number is extracted by the random number extracting means 112 from the random numbers generated by the random number generating means 111 of the winning lottery means 110. Then, the process proceeds to the next step 201.

At step 201, the extracted random numbers are stored inside the random number extracting means 112. Then, the process proceeds to the next step 202. In step 202, the random number extracted by the determination means 114 and the winning determination table 1
Comparison with thirteen winning determination area data is performed. And
Proceed to the next step 203.

In step 203, the determining means 114 determines which of the winning regions in the winning determination table 113 contains the extracted random numbers, and determines the evaluation of the lottery process. Then, the process proceeds to the next step 204. In step 204, the reel rotation stop control means 120 acquires a stop table based on the evaluation in step 203. Then, the lottery process ends.

The acquisition of the stop table performed by the reel rotation stop control means 120 in step 204 described above will be described with reference to the flowcharts of FIGS. The flow shown in FIG. 5 and FIG.
Corresponds to the first mode regarding the selection and determination of the stop table 121 performed by the user. Step 300 shown in FIG.
In, the stop control selecting means 122 determines whether or not the evaluation of the determining means 114 of the winning lottery means 110 is a winning. And
In the case of winning, the process proceeds to the next step 301.

In step 301, a lottery of a plurality of winning symbol stop tables is performed. That is, the stop control selecting unit 122 selects and determines one stop table from the winning advantage stop table and the winning disadvantage stop table by lottery. In addition, this lottery is performed using a lottery table,
A plurality of stop tables 121 defined in this lottery table
The lottery probability of each stop table 121 is determined by the ratio of the areas (the same applies to the second to fifth embodiments below). Then, the process proceeds to the next step 302.

In step 302, it is determined whether or not the determination by the stop control selecting means 122 is a winning advantage stop table. Then, if the determination is a winning advantage stop table, a winning advantage stop table is acquired. On the other hand, if it is not the winning advantage stop table, a winning disadvantage stop table is acquired. In the step 300, the winning lottery means
If the evaluation of the determination means 114 at 110 is not a winning, that is, if a loss is made, a loss stop table is acquired.

Incidentally, a loss stop table may be included in the lottery selection of the stop table in step 301. That is, in step 400 shown in FIG. 6, the stop control selecting means 122
Judge whether the evaluation is a prize. Then, in the case of a winning, the process proceeds to the next step 401. In step 401, a lottery of a plurality of winning symbol stop tables is performed. That is, the stop control selecting means 122 selects and determines one stop table from among the winning advantage stop table, the winning disadvantage stop table, and the loss stop table by lottery. Then, the process proceeds to the next step 402.

At step 402, it is determined whether or not the determination by the stop control selecting means 122 is a winning advantage stop table. Then, if the determination is a winning advantage stop table, a winning advantage stop table is acquired. On the other hand, if it is not a winning advantage stop table, the process proceeds to the next step 403. In step 403, it is determined whether or not the determination of the stop control selecting means 122 is a winning disadvantage stop table. If the determination is a winning disadvantage stop table, the winning disadvantage stop table is acquired. On the other hand, if it is not a winning disadvantage stop table, a loss stop table is acquired.

In step 400, if the evaluation of the determination means 114 of the winning lottery means 110 is not a winning, that is, if a loss occurs, a loss stop table is obtained. The flow shown in FIG. 7 corresponds to the second mode relating to the selection and determination of the stop table 121 performed by the stop control selecting means 122. In step 500, the stop control selecting means 122 determines whether or not the evaluation of the determining means 114 of the winning lottery means 110 is a winning. Then, in the case of a winning, the process proceeds to the next step 501.

At step 501, it is determined whether or not the gaming state satisfies a specific condition. When the gaming state corresponds to the specific condition, a winning advantage stop table is acquired. On the other hand, if the specific condition is not satisfied, a winning disadvantage stop table is acquired. In the step 500,
If the evaluation of the determination means 114 of the winning lottery means 110 is not a prize, that is, if it is a loss, a loss stop table is acquired.

The above description has been made on the case where the gaming state meets the specific condition as the hit period. However, when the game state meets the specific condition as the loss period, it is particularly illustrated. No, but in step 501
In the case where the game state satisfies the specific condition, the winning disadvantage stop table is acquired. The flow shown in FIGS. 8 and 9 corresponds to the third embodiment relating to the selection and determination of the stop table 121 performed by the stop control selecting means 122.

In step 600 shown in FIG. 8, the stop control selecting means 122 determines whether or not the evaluation of the determining means 114 of the winning lottery means 110 is a winning. Then, in the case of a winning, the process proceeds to the next step 601. In step 601, it is determined whether or not the gaming state meets a specific condition.
When the gaming state corresponds to the specific condition, a winning advantage stop table is acquired. On the other hand, if the specific condition is not satisfied, the process proceeds to the next step 602.

At step 602, lottery of a plurality of winning symbol stop tables is performed. That is, the stop control selecting means 122 selects and determines one stop table from the winning disadvantage stop table and the loss stop table by lottery. Then, the process proceeds to the next step 603. Step 60
In 3, it is determined whether or not the determination of the stop control selecting means 122 is a winning disadvantage stop table. If the determination is a winning disadvantage stop table, the winning disadvantage stop table is acquired. On the other hand, if it is not a winning disadvantage stop table, a loss stop table is acquired.

In step 600, if the evaluation of the determination means 114 of the winning lottery means 110 is not a winning, that is, if a loss occurs, a loss stop table is obtained. The lottery in step 602 may include a winning advantage stop table. That is, in step 700 shown in FIG. 9, the stop control selection unit 122 determines whether or not the evaluation of the determination unit 114 of the winning lottery unit 110 is a winning.
Then, in the case of a winning, the process proceeds to the next step 701.

At step 701, it is determined whether or not the gaming state meets a specific condition. When the gaming state corresponds to the specific condition, a winning advantage stop table is acquired. On the other hand, if the specific condition is not satisfied, the process proceeds to the next step 702. In step 702, a lottery of a plurality of winning symbol stop tables is performed. That is, the stop control selecting means 122 selects and determines one stop table from among the winning advantage stop table, the winning disadvantage stop table, and the loss stop table by lottery. Then, the process proceeds to the next step 703.

In step 703, it is determined whether or not the determination by the stop control selecting means 122 is a winning advantage stop table. Then, if the determination is a winning advantage stop table, a winning advantage stop table is acquired. On the other hand, if it is not the winning advantage stop table, the process proceeds to the next step 704. In step 704, it is determined whether or not the determination of the stop control selecting means 122 is a winning disadvantage stop table. If the determination is a winning disadvantage stop table, the winning disadvantage stop table is acquired. On the other hand, if it is not a winning disadvantage stop table, a loss stop table is acquired.

In step 700, if the evaluation of the determination means 114 of the winning lottery means 110 is not a winning, that is, if a loss occurs, a loss stop table is obtained. The flow shown in FIG. 10 corresponds to the fourth mode relating to the selection and determination of the stop table 121 performed by the stop control selecting means 122. In step 800, the stop control selecting means 122 determines whether or not the evaluation of the determining means 114 of the winning lottery means 110 is a winning. Then, in the case of a winning, the process proceeds to the next step 801.

At step 801, it is determined whether or not the gaming state meets a specific condition. When the gaming state corresponds to the specific condition, a winning disadvantage stop table is acquired. On the other hand, when the specific condition is not satisfied, the process proceeds to the next step 802. In step 802, a lottery of a plurality of winning symbol stop tables is performed. That is, the stop control selecting unit 122 selects and determines one stop table from the winning advantage stop table and the winning disadvantage stop table by lottery. Then, the process proceeds to the next step 803.

In step 803, it is determined whether or not the determination by the stop control selecting means 122 is a winning advantage stop table. Then, if the determination is a winning advantage stop table, a winning advantage stop table is acquired. On the other hand, if it is not the winning advantage stop table, a winning disadvantage stop table is acquired. In step 800, when the evaluation of the determination means 114 of the winning lottery means 110 is not a winning, that is, in the case of a loss, a loss stop table is acquired.

The flow shown in FIG. 11 corresponds to the stop control selecting means.
This corresponds to a fifth mode relating to selection and determination of the stop table 121 performed by the 122. In step 900, the stop control selecting means 122 determines whether or not the evaluation of the determining means 114 of the winning lottery means 110 is a winning. Then, in the case of a winning, the process proceeds to the next step 901.

At step 901, it is determined whether or not the gaming state meets a specific condition. When the gaming state satisfies the specific condition, the process proceeds to the next step 902. In step 902, a lottery of a plurality of winning symbol stop tables is performed. That is, the stop control selecting unit 122 selects and determines one stop table from the winning advantage stop table and the winning disadvantage stop table by lottery. The lottery probability at this time is set so that the winning advantage stop table is extremely high. Then, the process proceeds to the next step 903.

In step 903, it is determined whether or not the determination by the stop control selecting means 122 is a winning advantage stop table. Then, if the determination is a winning advantage stop table, a winning advantage stop table is acquired. On the other hand, if it is not the winning advantage stop table, a winning disadvantage stop table is acquired. If the game state does not correspond to the specific condition in the step 901, the process proceeds to the next step 905.

In step 905, a lottery of a plurality of winning symbol stop tables is performed. That is, the stop control selecting unit 122 selects and determines one stop table from the winning advantage stop table and the winning disadvantage stop table by lottery. The lottery probability at this time is set such that the winning disadvantage stop table is extremely high. Then, the process proceeds to the next Step 906.

In step 906, it is determined whether or not the determination by the stop control selecting means 122 is a winning advantage stop table. Then, if the determination is a winning advantage stop table, a winning advantage stop table is acquired. On the other hand, if it is not the winning advantage stop table, a winning disadvantage stop table is acquired. In the step 900, the winning lottery means
If the evaluation of the determination means 114 at 110 is not a winning, that is, if a loss is made, a loss stop table is acquired.

Although not particularly shown, the lottery of the stop table 121 in step 905 may be performed by using a winning disadvantage stop table and a loss stop table. Further, it may be performed by a winning advantage stop table, a winning disadvantage stop table, and a loss stop table. By the way, the above description has been made on the case where the gaming state corresponds to the specific condition as the hit period. However, when the game state corresponds to the specific condition as the loss period, the steps 902 and It can be executed by changing the lottery probability of each stop table in 905. That is, when the specific condition is satisfied, the lottery probability of the winning disadvantage stop table is set to be extremely high, and when it is not satisfied, the lottery probability of the winning advantage stop table is set to be extremely high.

(Other Embodiments Related to Stop Control) The stop control described above as an embodiment of the present invention is performed using a stop table. However, the stop control uses a stop table. It can be done without. This is to perform control such that when a certain prize is won in the lottery, a symbol (winning symbol) corresponding to the prize is stopped at a predetermined position as much as possible, and other symbols are not stopped.

Specifically, bits corresponding to the winning symbols are provided separately for winning symbols to be stopped and symbols not to be stopped. Then, first, control is performed so as not to stop symbols that should not be stopped, and then control is performed to stop symbols that should be stopped.
These controls are performed based on the data stored in the aforementioned bits.

In the case of this control method, kicking of a predetermined symbol and pulling in of a predetermined symbol are set in step 204 described with reference to FIG. That is,
The stop control selecting means 122 selects a predetermined stop control depending on whether a winning lottery result or a game state satisfies a specific condition. Regarding the flow representing the mode of the selection of the stop control, the “stop table” in FIGS.
Is replaced with “stop control”, and a description thereof will be omitted.

Then, the reel rotation stop processing of step 104 shown in FIG. 3 is as shown in the flow of FIG.
Note that “n” in the figure represents the maximum number of symbols that can be drawn in the stop control. That is, in step 1000, it is determined whether or not the kick setting has been achieved for a predetermined symbol. When it is determined that the setting of the kicking of the predetermined symbol has not been achieved, the process proceeds to the next step 1001.

In step 1001, the rotating reel 40 is rotated by one symbol. That is, kicking is performed for one symbol. Then, the next step 100
Proceed to 2. In step 1002, it is determined whether or not the number of the symbols obtained by rotating the rotary reel 40 by one symbol described above corresponds to the n-th symbol after the stop switch 50 is operated. Then, after the stop switch 50 is operated, if the number of symbols shifted by rotating the rotary reel 40 one symbol at a time is n, the process proceeds to the next step 1003.

In step 1003, the rotating reel 40
Stop the rotation of. Thus, the operation of the slot machine 10 from the insertion of the medal to the stop of the rotation of the rotating reel 40 is completed. If it is determined in step 1000 that the setting for kicking a predetermined symbol has been achieved, the process proceeds to the next step 1004.

In step 1004, it is determined whether or not a draw is set for any of the symbols. Then, when it is determined that the pull-in is set for any of the symbols, the process proceeds to the next step 1005. In step 1005, it is determined whether the pull-in setting has been achieved. If it is determined that the pull-in setting has been achieved, the process proceeds to the next step 1004.

If it is determined in step 1004 that no drawing is set for any of the symbols, the process proceeds to step 1003. Step 100
If it is determined in step 5 that the pull-in setting has not been achieved, the process proceeds to step 1001. Step 10
In 02, after the stop switch 50 is operated, the number of symbols shifted by rotating the rotary reel 40 one symbol at a time becomes n.
If not, the process returns to step 1000.

Steps 1001 through 10
The example described in 05 is an example of so-called minimum pull-in stop control, but may be maximum pull-down stop control.
