Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention sets a payout rate, which is a ratio of the total number of game media acquired by a player to the total number of game media loaded into a machine, to one of a plurality of predetermined levels. The present invention relates to a gaming machine equipped with a payout rate setting means for setting at one setting stage.

[0002]

2. Description of the Related Art Conventionally, such a gaming machine includes, for example, a slot machine. In the conventional slot machine, the extracted random number value is collated with the section data of the predetermined probability lottery table to determine the internal winning mode. The prizes given to the player according to the probability lottery result include various modes, which are roughly classified into a small hit, a medium hit, and a big hit. The winning modes of these various payouts occur when corresponding predetermined symbols are lined up on the winning line during the normal game.

In these internal winning modes, the winning probabilities differ depending on the payout rate set when the power of the slot machine is turned on. In the conventional slot machine, the payout rate is set to any one of the predetermined 6 stages, which sequentially increases from setting 1 to setting 6. The throwing rate is set by inserting a key into a setting key hole of a power supply box provided inside the main body of the slot machine when the power is supplied to the slot machine and rotating the slot machine.

The probability lottery table is prepared according to each of the six setting stages of the payout rate. In other words, the division data of each winning mode of each probability lottery table is set differently for each setting stage, and the probability lottery table corresponding to the higher setting stage has the higher winning probability of each internal winning mode. ing. Therefore, when selecting a gaming table, the player predicts the gaming table in which the payout rate is set in a high setting stage such as setting 4, 5, 6 and expects that the internal winning probability of each winning mode is high. Play a game.

[0005]

However, in the above-mentioned conventional slot machine, since the stage of setting the payout rate is preset inside the main body of the slot machine when the power of the slot machine is turned on, etc. During this time, the player could not recognize the setting stage from outside the slot machine. Therefore, the player has no choice but to predict the setting stage of the payout rate of the game table based on his own experience and intuition. For this reason, even if the gaming table is set to a low stage such as the payout rate of 1 or 2, the player may believe that the gaming table is set at a high level and lose the game by continuing to play the game. In addition, you can move from a game console that is playing to another game console,
The player could not decide whether he should stop or continue the game on the game table based on his own experience and intuition, and sometimes hesitated.

[0006]

The present invention has been made to solve the above problems, and shows the ratio of the total number of game media acquired by a player to the total number of game media loaded into a machine. In a gaming machine equipped with a payout rate setting means for setting the payout rate to one of a plurality of predetermined settings, there are setting steps other than the setting steps set by the payout rate setting means. It is characterized in that it is provided with a setting notifying means for notifying that the setting is not made and notifying the setting stage set by the payout rate setting means.

In such a configuration, since the actually set payout rate setting stage is not notified, the player can predict the set payout rate setting stage to some extent.

Further, the present invention is characterized in that the setting notifying means notifies with a predetermined probability that each setting step other than the setting step set by the payout rate setting means is not set.

In such a configuration, each setting step that has not been set is notified with a predetermined probability, and the player can narrow down the prediction of the setting step that is set each time the notification is made.

The present invention is also characterized in that the setting notifying means notifies each time a predetermined condition is satisfied, a setting stage not set by the payout rate setting means.

In such a configuration, notification is given each time a predetermined condition is met.

Further, according to the present invention, the predetermined condition is that the predetermined internal prize mode is determined by the prize mode determination means for determining the internal prize mode by lottery after the specific game is finished or after the power is turned on. It is characterized in that another predetermined internal winning mode is determined by the mode determining means.

In such a structure, for example, after the jackpot winning or after the power is turned on, the setting stage is notified every time another predetermined internal winning mode is internally won until a predetermined internal winning mode is determined. It

Further, according to the present invention, the setting notifying means notifies that the setting stage other than the setting stage set by the payout rate setting means is not set by the display mode of the display device that directs the game. It is characterized by

In such a configuration, the display device is controlled in a display mode corresponding to the set stage of the set payout rate. Therefore, the player looks at the display mode of the display device,
It is possible to recognize the setting stage of the set payout rate.

Further, in the present invention, the display device is built in a plurality of rotating reels on which various symbols are drawn on the outer periphery, and each of the rotating reels illuminates the symbols stopped and displayed from behind, for each rotating reel. Is a plurality of reel back lamps provided in the.

That is, the microcomputer 81 controls the sound source IC 91 and the power amplifier 95 in accordance with the instruction input from the main control board 61 via the main control unit communication port 88 to make a medal insertion sound, a start lever operation sound, and a stop button operation sound. The speaker 9 outputs game sound effects such as sound effects during bonus and sound effects produced according to the game processing.
Output from 6,96.

FIG. 10 conceptually shows a probability lottery table which is stored in the program ROM 65 of the main control board 61 and is used in the normal gaming state. This probability lottery table is used to classify the random numbers extracted by the sampling circuit 70 during the normal game into each winning mode, and the data for partitioning the random number within a certain range generated by the random number generator 69 into each winning mode. I remember. Microcomputer 63
Constitutes a prize mode determining means for determining an internal prize mode by lottery. A1 to a3 and b1 in FIG.
b3, c1 to c3, d1 to d3, e1 to e3, f1 to f
Reference numeral 3 is preset numerical data, which is used when the random number extracted by the sampling circuit 70 is divided into each winning mode. This data is “a1 to f1” when the number of inserted medals is one, “a2 to f2” when the number of medals is two,
In the case of three sheets, a combination of numerical values of "a3 to f3" is used.

These numerical values are usually "a <b <c <d <e <
If the extracted random number value is less than c, the small hit prize (small hit) is set, and in this case,
If it is less than a, the "cherry" hit request flag is set, if it is a or more and less than b, the "capital letter" hit request flag is set, and if it is b or more and less than c, the "three shakudama" hit request flag is set. If the extracted random number value is greater than or equal to c and less than d, the "replay" per-request flag is set. If the extracted random number is greater than or equal to d and less than e, a medium hit is awarded (medium hit) and the "RB" hit request flag is set. If the extracted random number is greater than or equal to e and less than f, a big hit is awarded ( It becomes a big hit) and the request flag per "BB" is set. If it is f or more, it is a "miss" without winning. That is, the winning mode is determined by which one of the sampled random numbers belongs to which numerical range, and is represented by the winning request flag.

In this embodiment, this probability lottery table is prepared corresponding to each setting stage from setting 1 to setting 6. The division data of each probability lottery table is set to a value that leads the payout rate of each setting stage 1 to 6 shown in FIG. That is, the payout rate of the slot machine 1 is almost determined by the winning probability of each internal winning mode in the probability lottery process.

The symbol table stored in the program ROM 65 is conceptually shown in FIG. This symbol table is for associating the rotation positions of the reels 2 to 4 with symbols, and represents the symbol arrays shown in FIG. 3 by symbols. This symbol table shows code numbers sequentially assigned at a constant rotation pitch of each reel with reference to the rotation position at which the above-mentioned reset pulse is generated, and symbols provided corresponding to each code number. The symbol code and are stored. In the example shown in the figure, when the first reel 2 stops at the rotation position of the code number "16" from the reference position, a symbol corresponding to the code "G" appears in the center of the display window 5, and above and below it. Symbols corresponding to the codes "C" and "A" respectively appear.

A prize symbol combination table is stored in the program ROM 65. In this winning symbol combination table, the symbol code of each winning symbol combination shown in FIG. 6, the symbol code of the symbol combination forming the “reach eyes”, the winning determination code indicating each winning, the number of winning medal dividends, etc. are stored. Has been done. Here, the reach pattern is a symbol combination that suggests that the BB game is about to occur to the player when the “BB” hit request flag has been set. This winning symbol combination table is referred to when the stop control of the first reel 2, the second reel 3 and the third reel 4 is performed and when the winning confirmation after all reels are stopped is confirmed. Further, the program ROM 65 stores a sequence program for executing a game on the slot machine 1.

In addition, the program RO of the sub control board 62
M83 stores, for example, an effect group lottery table shown in FIG. 12, which is referred to in an effect group selection process described later, and a setting determination effect lottery table shown in, for example, FIG. 13, which is referred to in a setting determination effect selection process. Has been done.

In the production group lottery table shown in FIG. 12, four production groups corresponding to the setting stages set by the payout rate setting means are prepared in advance in accordance with the respective setting stages 1 to 6. It is a table that is selected from 1 to 4 by lottery. The total value for each of the settings 1 to 6 of the random number width shown in the table is 128, and the range of the extracted random numbers is 0 to 127.
In each of the settings 1 to 6, the effect groups 1 to 4 are equally selected with a probability of 32/128.

The setting discrimination effect lottery table shown in FIG. 13 is selected by lottery from the effect groups selected in the lottery using the effect group lottery table.
It is a table for selecting one effect. In this table, four types classified into effect groups 1 to 4 are prepared for each setting 1 to 6, and the total value of the random number widths for each effect group 1 to 4 is 100, The range of the extracted random numbers is 0 to 99. Although not shown,
The setting discrimination effect lottery tables of the effect groups 3 and 4 for setting 2 and the setting discrimination effect lottery tables of the effect groups 1 to 4 for settings 3 to 6 are also prepared similarly.

In the table, "(X) not production (X = 1 to 1
The item “6)” indicates an effect for notifying that the setting stage is not set to the (X) stage. This production is performed by reel back lamps 47a, 47b, 47c of each reel 2-4.
The flash pattern is used as described later. Each "(X) not effect" is performed with a predetermined probability. For example, when the setting stage of the payout rate is set to setting 1, when the setting determination effect lottery table of the effect group 1 for setting 1 is selected, "2not effect", "3not effect", "4not effect". , "5not production", "6no
The probabilities of "t effect" are 20/100, respectively. Further, when the setting discrimination effect lottery table of the effect group 2 for setting 1 is selected, the probability of performing “2not effect” is 10/100, the probability of performing “3not effect” is 20/100, and “4not effect”. Is 3
0/100, the probability that "5not production" will be performed is 10 /
100, the probability that "6not production" will be performed is 30/10
It is 0. Hereinafter, similarly, in each of the other setting determination effect lottery tables, each “(X) not effect” is performed with a predetermined probability.

Next, the operation of the slot machine 1 of this embodiment controlled by the control circuit described above will be described.

14 to 16 are flowcharts showing the outline of the main game processing controlled by the main CPU 64 of the main control board 61.

In the main game process, the initialization process at the start of the game is first performed (see step 111 in FIG. 14). In this initialization processing, the control RAM 66 is cleared, and a sub-control unit communication port 79 transmits an effect initialization command to the sub-control board 62, so that the main control board 61
Communication data between the sub-control board 62 is initialized.

Next, the main CPU 64 performs a RAM clear process at the end of the game to erase the data stored in the control RAM 66 at the end of the previous game (step 1).
12). Next, as a result of the previous game, replay (replay)
CPU 6 determines whether or not there is a request to automatically insert medals.
It is determined by 4 (step 113). If there is this automatic insertion request, then the game medals corresponding to the insertion request are automatically inserted (step 114). On the other hand, if there is no automatic insertion request, the player next inserts a medal into the medal insertion slot 8 and inputs a detection signal from the medal sensor 8S, or the stored medal insertion switches 25 and 26.
The operation waits until the closing signal is input by the operation (step 115).

Next, by operating the start lever 28,
It is determined whether or not there is a start signal input from the start switch 28S (step 116). If this determination is "YES", then it is determined whether or not 4.1 seconds have elapsed from the previous game (step 117). 4.
If 1 second has not elapsed, the game start waiting time is exhausted until 4.1 seconds have elapsed (step 118). When 4.1 seconds have passed from the previous game, next, the random number generator 69
The random number for lottery generated in step S119 is extracted by the sampling circuit 70 (step 119), and then the above-mentioned 4.1.
A game monitoring timer for counting seconds is set (step 120).

Next, a probability lottery process is performed based on the random numbers extracted in step 119 (FIG. 15, step 1).
21). This probability lottery process is performed by the sampling circuit 7
It is carried out by determining which one of the winning groups the one random value identified by 0 belongs to in the probability lottery table (see FIG. 10). At this time, the probability lottery data a1 to f shown in each stage of the probability lottery table of FIG. 10 according to the number of medals inserted into the machine.
1, a2-f2, or a3-f3 are set, and the probability lottery is performed.

FIG. 17 is a diagram showing an example of data when betting three coins, which corresponds to the probability lottery table shown in FIG. This figure shows data when the range of the extracted random numbers is 0 to 16383. When the probability lottery process is performed by using this probability lottery table, for example, if a random number 4050 is extracted in the normal gaming state, the “three shakutama” wins the small win prize mode partitioned by the probability lottery data c3. As a result, the request flag for hitting three shaku balls is set in the control RAM 66. Further, for example, if the random number 6650 is extracted in the normal gaming state, it means that the BB partitioned by the probability lottery data f3 has been won, and the request flag per BB is set.

When the probability lottery process is completed, next, a reel rotation process is performed (see step 122 in FIG. 15), and then a start command transmission process is performed (step 123). In the reel rotation process, first, a predetermined area of the control RAM 66 in which the rotational positions of the reels 2 to 4 are written is initialized by the main CPU 64 at the start of the reel rotation, and subsequently, the reels 2 to 4 are rotated by the stepping motor 45. Driven. In the start command transmission process, the main switch from the start switch 28S
Based on the start signal input to the PU 64, a start command is transmitted to the sub control board 62 side via the sub control unit communication port 79. The parameters of this start command include information such as the type of hit request flag established as a result of the probability lottery in step 121 and the game state at that time.

Next, any of the stop buttons 29 to 31
It is determined whether or not is turned on (step 12).
4). If the ON operation has not been performed, it is determined whether or not the automatic stop timer has reached 0 (step 12).
5). This automatic stop timer uses the stop button 29-
This is for automatically stopping the reels 2 to 4 after a lapse of a predetermined time when 31 is not operated for a predetermined time.

When any of the stop buttons 29 to 31 is turned on or when the automatic stop timer becomes 0, the number of symbols drawn on the activated pay line, that is, the number of sliding symbols is determined. (Step 1
26). The number of sliding frames is determined based on the game state, winning request, number of control frames, symbol position, etc. If the number of frames from the activated winning line to the winning symbol is within the range of control frames, it is determined as the number of sliding frames. It Next, the number of sliding frames is stored in a predetermined area of the control RAM 66. After that, the stop request flag of the first stop reel is set, and in response to the stop request flag being set, reel pull-in control is performed in which the first stop reel is rotated by the determined number of slide frames, and 1 The rotation of the individual reels is stopped (step 127).

Next, it is judged whether or not all reels 2 to 4 have stopped (step 128). If the second stop reel and the third stop reel have not stopped, the process returns to step 124 and the above process is repeated.

When all reels 2 to 4 are stopped, next,
The main CPU 64 performs a winning search process (see step 129 in FIG. 16). In this prize search process,
The type of the winning flag indicating the combination of symbols actually aligned on the activated winning line and the type of the internal winning combination determined by the probability lottery process are matched. Then, it is determined whether or not the winning flag is normal (step 130). If this determination result is not normal, for example, when the symbol combination of “capital letters” is aligned on the activated pay line, but the hit request flag corresponding to the internal winning combination is the flag of “cherry”, An illegal error is displayed on the payout number display portion 20 (step 131).

If the winning flag is normal, then the game medals are stored or paid out depending on the state at that time (step 132). In other words, if the game is being played with credits, the number of stored coins displayed in the accumulated coin number display unit 16 is increased by the number of medals obtained by winning, and the game is inserted by inserting medals into the medal insertion slot 8. In the state in which is performed, the number of medals obtained by winning is paid out to the medal tray 32.
When the medals are stored or paid out, the WIN lamp 19 is turned on (step 133) to notify the player of the medal acquisition.

Next, the main CPU 64 determines whether or not the current game state is the operation of the BB game or the RB game (step 134). When the BB game or the RB game is not running, the main CPU 64
The game process by returns to step 112, and the next new game is started. If the BB game or the RB game is in operation, then the number of games of the BB game or the RB game is checked by the main CPU 64 (step 135).

Subsequently, the main CPU 64 determines whether or not the current game state is at the end of the BB game (step 136). If it is the end of the BB game, the RAM clear process at the end of the BB game is performed on the control RAM 66 (step 137), and then the game process returns to step 112 to start the next new game. If it is not the end of the BB game in step 136, the game process returns to step 112 and the next new game is started.

Next, the sub CPU 82 of the sub control board 62
The outline of the game process controlled by the following will be described with reference to the general flowchart shown in FIG.

First, it is determined whether or not the setting notification state is present at present depending on whether or not the setting notification state flag is set (see step 201 in FIG. 18). If it is in the setting notification state, it is subsequently determined whether or not the internal winning combination is a "three shakutama" prize (step 202). When the internal winning combination is “Sanjakutama” winning, next, a random number is acquired (step 203), and subsequently, setting determination effect selection processing is performed based on the acquired random number (step 20).
4). Then, the reel lamp back lamp 47 according to the setting determination effect selected in the setting determination effect lottery process.
Light emission control is performed on a, 47b, and 47c, and an effect is executed by the flash pattern (step 205).

19 and 20 are flow charts showing the details of the game processing controlled by the sub CPU 82.

First, it is determined whether or not a star command has been transmitted from the main control board 61 (see step 301 in FIG. 19). The start command is transmitted to the sub control board 62 side via the sub control unit communication port 79 of the main control board 61 in the start command transmission processing of the main game processing (see step 123 in FIG. 15) as described above, Sub-CP via control communication port 88
It is received by U82. As described above, the parameters of this start command include information such as the type of hit request flag established as a result of the probability lottery and the gaming state at that time.

When the start command has not been received, it is next determined whether or not the current game state is at the end of the BB game or at the time of power-on of the slot machine 1. (See step 302 in FIG. 20). The determination at the end of the BB game is that the BB game end command transmitted from the main control board 61 is received when it is determined at step 136 (see FIG. 16) of the main game process that the game state is the end of the BB game. And "Y
When the BB game is over or the power is turned on, the setting notification state flag is subsequently set in a predetermined area of the control RAM 84 and turned on (step 30).
3).

On the other hand, if it is determined in step 302 that the current game state is neither the end of the BB game nor the start-up of the power source, it is next determined whether or not the setting is changed (step 304). This determination is performed by determining whether or not the setting at the setting stage has been performed by operating the reset switch 35, the setting key type switch 36, and the start lever 28 described above. If the setting is not changed, the process returns to the beginning step 301.
The currently set value of the payout rate is rewritten every time the setting stage is changed, transmitted from the main control board 61, and stored in the control RAM 84.

When it is time to change the setting, next, a random number is extracted from the random number range 0 to 127 (step 305), and an effect group selection process is performed based on the extracted random number (step 306). In this production group selection process,
The above-mentioned production group lottery table (see FIG. 12) is referred to, and one production group is selected from the production groups 1 to 4 corresponding to the newly set setting stage based on the extracted random numbers. For example, when the setting stage is newly set to setting 2 and the random value 50 is extracted, the production group 2 is selected by referring to the setting 2 column of the table. The setting determination effect lottery table of the selected effect group is newly set and updated in the control RAM 84. Then, the process returns to step 301. When the slot machine 1 is installed, the setting stage is automatically set to 1 and the effect group is set to 1 when the power is turned on.

If it is determined in step 301 that the start command has been received, then it is determined whether the internal winning mode is a predetermined winning mode, for example, "cherry" winning mode (FIG. 19). , Step 307). This determination is performed by determining the type of the hit request flag included in the parameter of the start command. When the internal winning mode is "cherry", the setting notification state flag set in the predetermined area of the control RAM 84 is reset and turned off (step 308), and the process returns to step 301. On the other hand, if the internal winning mode is not "cherry", then it is determined whether or not the setting notification state flag is ON (step 3).
09). When the setting notification state flag is OFF, the processing returns to step 301. On the other hand, the setting notification state flag is O
When the result is N, it is subsequently determined whether or not the internal winning mode is a predetermined other winning mode, for example, "three shakutama" winning mode (step 310). If the internal winning mode is not “three shakudama”, the process returns to step 301. On the other hand, when the internal winning mode is “Sanshakutama”, the random number range 0 to
A random number is extracted from 99 (step 311), and setting determination effect selection processing is performed based on the extracted random number (step 312). In this setting determination effect selection process, the setting determination effect lottery table (see FIG. 13) selected in the above-described effect group selection process (see step 306) and set in the control RAM 84 is referred to, and based on the extracted random number, the above-described. "(X) not effect" is selected. For example, as described above, when the effect group 2 is selected in the setting 2, when the random number value 35 is extracted by this random number lottery, “4 not” is selected from the table of the effect group 2 for setting 2 shown in FIG. "Direction" is selected.

Next, all reels 2 in the main game process
4 to 4 are stopped and a reel stop command is received from the main control board 61, a reel lamp effect corresponding to the determined "(X) not effect" is executed (step 31).
3). In this reel lamp production, the decided "(X) n"
The reel lamp back lamps 47a, 47b, 47c of the reels 2 to 4 are controlled to emit light in accordance with the "ot effect", and the flash pattern informs that the setting stage of the setting (X) is not set.

FIG. 21 is a diagram showing an example of a reel lamp effect corresponding to the “4not effect” selected as described above, for example, and the setting stage is set to a setting stage other than the setting 4. The effect shown to the player is shown.

In the figure, the display of (1), (2), and (3) in the "flash pattern" column is for reel 2,
The lighting states of the upper reel back lamps 47a of 3 and 4 are shown respectively, and the indications (4), (5), and (6) are shown respectively for the middle reel reel lamps 47b, (7), and
The indications (8) and (9) are for the reel back lamps 4 at the bottom
The lighting states of 7c are shown. In these displays, the shaded portion indicates the lamp lit state, and the non-hatched portion indicates the lamp extinguished state. In addition, the "stage" column in the figure shows the stage of elapsed time, and the reel back lamps 47a, 47b,
47c is turned on or off at each of these stages as illustrated.

In the flash pattern of "4not effect" shown in the figure, when all reels 2 to 4 are stopped, first, the reel back lamp (1) on the upper stage of the first reel 2 is turned on as shown in stage 1. It Subsequently, as shown in step 2, the middle reel back lamp (4) of the first reel 2 is turned on, and further, as shown in step 3, the middle reel back lamp (5) of the second reel 3 is turned on. It is lit. Further subsequently, as shown in step 4, the middle reel back lamp (6) of the third reel 4 is turned on, and thereafter, as shown in step 5, step 6, and step 7, Reel back lamp (2), second reel 3
The reel back lamp (5) in the middle stage and the reel back lamp (8) in the lower stage of the second reel 3 are turned on in this order. Then, as shown in step 8, an upper reel back lamp (1) of the first reel 2, a middle reel back lamp (5) of the second reel 3, and a lower reel back lamp (9) of the third reel 4. Are simultaneously lit, and subsequently, as shown in step 9, the upper reel back lamp (3) of the third reel 4, the middle reel back lamp (5) of the second reel 3, and the lower reel of the first reel 2 The reel back lamps (7) are turned on at the same time.

In such "4not production", the stage 1
The number "4" is displayed by the series of flash patterns in steps 7 to 7, and the mark "x" is displayed by the flash patterns in steps 8 and 9. That is, this flash pattern “4 ×” informs that the setting stage of setting 4 is not set.

According to the slot machine 1 of the present embodiment as described above, it is "(X) not" that no setting stage other than the actually set payout rate setting stage is set.
It is notified by the flash pattern of "effect", and the setting stage actually set is not notified. Therefore, the player can conversely predict the actually set payout rate setting stage to some extent. As a result, the player can recognize the actually set payout rate setting stage to some extent, and the player continues the recognized payout rate setting stage to another game machine or to stop the game. It can be used as a judgment material when making a decision on a strategy such as whether it should be done. For this reason, believing that the setting stage of the set payout rate is not understood at all or is high, it is possible to lose money by continuing to play the slot machine 1 in which the payout rate is set low. Disappear.

Further, according to the present embodiment, the "(X) not effect" for notifying each setting step that has not been set is set because it is determined based on the setting discrimination effect lottery table (see FIG. 13). Each setting step that does not exist is notified with a predetermined probability. Therefore, the player can narrow down the prediction of the actual setting stage each time the notification is given. Therefore, the enjoyment of predicting the setting stage occurs, and the interest of the slot machine game increases.

According to the present embodiment, after the BB game is over or the slot machine 1 is powered on, the "cherry ball" winning mode is internally won before the "cherry" winning mode is internally won. Every time a predetermined condition is satisfied, the "(X) not effect" is executed to notify the player that each setting stage other than the set setting stage is not set. Therefore, the player is expected to perform the "(X) not effect", and the interest of the setting stage notification increases. In addition, until "Cherry" is internally won, the "(X) not effect" may be repeated many times, and while it may be possible to reliably recognize the setting stage, once "Cherry" is immediately won internally, Also, there is a possibility that "(X) not production" will not be performed, which makes the slot machine game more interesting.

Further, according to the present embodiment, "(X) not
"Production" is performed based on the flash pattern of the reel back lamps 47a, 47b, 47c built in each reel 2-4. Therefore, in addition to the conventional effects such as the illumination of the symbols and the notification of the bonus internal winning mode, the elements of the setting discrimination effect by the reel back lamps 47a, 47b, 47c are further added, and the interest of the slot machine game is increased.

In the present embodiment, the case where the gaming machine according to the present invention is applied to the slot machine has been described. However, a ball game machine including a pachinko machine having a function of setting the payout rate in a plurality of stages. It can also be applied to other game machines such as. Even in this case, the same operation and effect as those of the above-described embodiment can be obtained.

[0105]

As described above, according to the present invention, since the actually set payout rate setting step is not notified, the player predicts the set payout rate setting step to some extent. You can do it. As a result, the set payout rate setting stage can be recognized to some extent, and the player should move the set payout rate setting stage to another gaming table, stop the game, or continue the game. It can be used as a judgment material when making a decision about the capture. For this reason, there is no need to believe that the setting stage of the set payout rate is set at all, or believe that it is a high setting, and continue to play on a gaming machine with a low set payout rate to lose money. .

Further, when the configuration is such that each setting stage other than the setting stage set by the payout rate setting means is set with a predetermined probability, each setting stage not set is set to a predetermined setting. With probability
The player can narrow down the prediction of the setting stage set each time the notification is made. Therefore, the enjoyment of predicting the setting stage occurs, and the interest of the game increases.

Further, in the case where the setting stage which is not set by the payout rate setting means is notified every time the predetermined condition is satisfied, the notification is performed every time the predetermined condition is satisfied. Therefore, the player is expected to be notified of the setting stage, and the interest of the setting stage notification is increased.

Further, the predetermined condition is determined by the prize mode deciding means until the predetermined internal prize mode is determined by the prize mode deciding means for deciding the internal prize mode by lottery after the specific game is finished or after the power is turned on. When another predetermined internal winning mode is determined, for example, after the jackpot winning completion or after turning on the power, the degree of internal winning of another predetermined internal winning mode until the predetermined internal winning mode is determined. Is notified of the setting stage. Therefore, the setting stage is informed many times until the predetermined internal winning mode is determined,
While there is a possibility that the setting stage can be recognized with certainty, there is a possibility that a predetermined internal winning mode will be immediately determined and will not be notified even once, which will increase the fun of the game.

In the case where the display mode of the display device for playing the game is used to notify that the setting stage other than the setting stage set by the payout rate setting means is not set, the set output is set. The display device is controlled in the display mode corresponding to the setting stage of the ball rate. Therefore, the player
The setting stage of the set payout rate can be recognized by looking at the display mode of the display device.

Further, the display device is built in a plurality of rotating reels on which various symbols are drawn on the outer periphery, and each of the rotating reels illuminates the symbols stopped and displayed from behind, and is provided for each rotating reel. When the reel back lamp is configured by a plurality of reel back lamps, the reel back lamp illuminates the symbol of each rotating reel and notifies the setting stage of the payout rate set based on the lighting pattern and the like. Therefore,
The element of the production by the reel back lamp is further added,
The interest of games will increase.
