Winning probability data storage means 55 for storing so-called winning probability data composed of high winning probability data with high probability
With the input of the normal probability determination signal from the probability determination means 53, while selecting the normal winning probability data stored in the winning probability data storage means 55, on the condition that the high probability determination signal is input, Probability selecting means 54 for selecting the high winning probability data stored in the winning probability data storage means 55
And a winning lottery means 56 for randomly selecting one random number value from the random number values sequentially generated from the random number generating means 52, a random number value drawn by this winning lottery means 56 and a normal winning probability of the winning probability data storage means 55. Based on the data or the high winning probability data, a winning determination means 59 for determining a winning and outputting a winning signal is provided.

It should be noted that the probability determining means 53 selects either to shift to a high probability or to maintain the current state when the current state is a normal probability, while on the other hand, when the current state is a high probability, The lottery probability data is provided to select either the normal probability or the current state. Also, FIG.
As shown in FIG.
And the sound effect generating means 58, the lamp 30 and the speaker 31 connected to the output side of the central control device 50, the specific probability notification means 60 for notifying the player that the normal probability is changed to a high probability is formed. Has been done.

The operation of the slot machine 10 thus configured will be described with reference to the block diagram shown in FIG. First, insert a medal from the medal insertion slot 22 (Fig. 2),
Alternatively, the slot machine 10 waits for the start signal from the start switch 25 depending on whether the credit medal insertion switch 24 (FIG. 2) is operated to insert the stored credit medal.

As shown in FIG. 1, when the player operates the start switch 25, the start switch 25 outputs a start signal to the probability lottery means 51 and the winning lottery means 56. By inputting this start signal to the probability lottery means 51, the probability lottery means 51 becomes a random number generating means.
One random number is randomly selected from the random numbers generated from 52,
The probability lottery signal is output to the probability determining means 53.

Next, as shown in FIG. 1, the probability lottery means 51.
By inputting the probability lottery signal from the probability determination means 53, the probability determination means 53, based on the random number value drawn by the winning lottery means 56 and the lottery probability data held inside the probability determination means 53. , Normal probability or high probability is determined.
That is, specifically, when the current state is the normal probability, it is determined whether to shift to the high probability or to maintain the current state, and when the current state is the high probability, to shift to the normal probability or maintain the current state. Determine whether to do.

When the judgment result is the normal probability, the probability judging means 53 outputs the normal probability judging signal to the lamp lighting control means 57, the sound effect generating means 58 and the probability selecting means 54. On the other hand, when the determination result is high probability, the probability determination means 53 outputs a high probability determination signal to the lamp lighting control means 57, the sound effect generation means 58, and the probability selection means 54.

When the normal probability judgment signal or the high probability judgment signal is input to the lamp lighting control means 57 as shown in FIG. 1, the lamp lighting control means 57 lights the lamp 30 based on these signals. Control whether or not. That is, specifically, when the current state has a high probability and the lamp 30 is lit, the normal probability determination signal is the lamp lighting control means.
When it is input to 57, the lamp 30 is turned off, while when the high probability determination signal is input, the lamp 30 continues to be turned on. Also, if the current situation is a normal probability and the lamp 30 is off,
When the high probability judgment signal is input, turn on the lamp 30,
On the other hand, when the normal probability determination signal is input, the lamp 30 remains off.

Further, when the normal probability judgment signal or the high probability judgment signal is inputted to the sound effect generating means 58 as shown in FIG. 1, the sound effect generating means 58, based on the judgment by the probability judging means 53, It controls whether or not a sound effect is generated from the speaker 31. That is, specifically, when the sound probability is currently generated from the speaker 31 and the normal probability determination signal is input to the sound effect generation means 58, the sound effect is not generated from the speaker 31. If the high probability judgment signal is input to the sound effect generating means 58, the speaker 31 is stopped.
Keeps producing sound effects. Further, if the present situation is that the sound effect is not generated from the speaker 31 with the normal probability, when the high-probability determination signal is input to the sound effect generating means 58, the speaker 31 starts generating the sound effect, while the normal probability is generated. When the determination signal is input to the sound effect generating means 58, the speaker 31 still stops generating the sound effect.

In the present embodiment, it has been described that the speaker 31 continuously outputs the sound effect during the high probability, but the sound effect generated from the speaker 31 changes from the normal probability to the high probability. In some cases, or only when the high probability shifts to the normal probability, it may be generated. Further, as shown in FIG. 1, when the normal probability determination signal or the high probability determination signal is input to the probability selecting means 54, the probability selecting means 54 causes the normal winning probability data stored in the winning probability data storage means 55 or Select high winning probability data.
That is, specifically, the probability selecting means 54 is the probability determining means.
On the condition that the normal probability determination signal from 53 is input, the normal winning probability data stored in the winning probability data storage means 55 is selected, and the probability of winning is determined on the condition that the high probability determination signal is input from the probability determining means 53. The high winning probability data stored in the data storage means 55 is selected.

Then, the probability selecting means 54 sends the normal winning probability data or the high winning probability data selected from the winning probability data storing means 55 to the winning determination means 59. In addition,
High probability means the winning probability of a specific winning form of normal probability is 10
It has been increased by a factor of 2,
For example, the winning probability when "BAR, BAR, BAR" is set in 17 to 21 is increased to 10 times the normal probability.

Further, as shown in FIG. 1, when the start signal is inputted to the winning lottery means 56, the winning lottery means 56 selects one of the random number values sequentially generated from the random number generating means 52, The lottery signal is output to the winning determination means 59. Next, as shown in FIG. 1, when the lottery signal from the winning lottery means 56 is input to the winning determination means 59, the winning determination means 59 causes the probability selection means 54 to obtain the normal winning probability data or the high winning probability data. Based on, it is determined whether or not the randomly selected random value has won.

After that, when the randomly selected random number is won,
As shown in FIG. 1, the winning determination means 59 outputs a winning signal to the game control means 41 and the medal payout means 40. And
As shown in FIG. 1, when a prize signal is input from the prize determination means 59 to the game control means 41, the game control means 41 operates a prize lamp (not shown) or the like that informs the prize by light or the like.

Further, as shown in FIG. 1, when a winning signal is input from the winning determination means 59 to the medal payout means 40, the medal payout means 40 pays out a predetermined number of medals to the player. Specifically, a predetermined number of medals are paid out to the player from the medal discharge port 29 (FIG. 2) at the lower front of the slot machine. Next, the operation of the slot machine 10 having the above configuration will be described with reference to the flowcharts shown in FIGS.

First, as shown in FIG. 3, the routine proceeds to step 71, where it is judged whether or not the accessory continuous operation increasing device is in operation. This determination is specifically carried out by the winning determination means 59 (FIG. 1). In addition, the fact that the accessory continuous operation increasing device is operating means that the so-called “large bonus” is being performed. In the above step 71, if the accessory continuous operation increasing device is not operating, that is, if the "large bonus" is not in progress, as shown in FIG. 3, the process proceeds to step 72, and it is determined whether or not the "bonus game" is in progress. do. In the "bonus game", for example, a "large bonus" in which "seven, seven, seven" are lined up in predetermined lines 17-21 or in a predetermined line 17-21, for example, "BAR, BAR,"
After winning the "Single Bonus" where "BAR" is lined up, "JA
It means that it is in "C game". This determination is also specifically made by the winning determination means 59 (FIG. 1). Here, the "JAC game" means that after inserting one medal and rotating the rotary reels 11 to 13, the stop switch 26
~ 28 is operated to stop each of the rotating reels 11 to 13, among the symbols of the stopped rotating reels 11 to 13, [JA
This is a game in which the payout of medals is carried out when three symbols including the characters C] are aligned on the center line 17.

If it is determined in step 72 that the "bonus game" is not in progress, that is, if the "JAC game" is not in progress, the process proceeds to step 73 and the "bonus game" flag is established, as shown in FIG. It is determined whether or not This determination is specifically made by the winning determination means 59.
(FIG. 1). In step 73 above,
If the flag of the "bonus game" is not established, as shown in FIG. 3, the process proceeds to step 74, and the lottery probability data of the lottery probability data of the bonus corresponding to the setting or the number of games is selected. Specifically, the probability lottery means 51 (FIG. 1) draws one from the random number values sequentially generated by the random number generation means 52 (FIG. 1).

After the lottery probability data has been switched in step 74, the step 75 is executed as shown in FIG.
Proceed to to determine whether or not the result of the lottery corresponds to winning. Specifically, the probability determination means 53 (FIG. 1) makes a determination based on the probability lottery signal from the probability lottery means 51 (FIG. 1). When it is determined in step 75 that the result of the lottery probability data switching lottery is winning, as shown in FIG. 3, the process proceeds to step 76, and the winning probability is changed. That is,
When the current situation is the normal probability, the specific winning probability is increased to 10 times, and the high probability is obtained. When the current situation is the high probability, the normal probability is obtained. Specifically, based on the probability determination signal from the probability determination means 53 (FIG. 1), the probability selection means 54 (FIG. 1) changes the lottery probability data from the winning probability data storage means 55 (FIG. 1) to the normal winning probability. It is processed by changing to data or high winning probability data.

In step 76, after selecting either the normal probability or the high probability, the process proceeds to the next step 77, in which the lamp 30 and the speaker 31 are output as shown below. Control. When the current state is high probability, when the normal probability determination signal is input to the lamp lighting control means 57, the lamp 30 that has been turned on is turned off, whereas when the high probability determination signal is input, the lamp 30
Keeps on.

When the current probability is normal probability, when the high probability judgment signal is input, the lamp 30 that has been turned off is turned on, whereas when the normal probability judgment signal is input, the lamp 30 is turned on.
Remains off. Further, when the current probability is high, when the normal probability determination signal is input to the sound effect generating means 58, the generation of the sound effect from the speaker 31 is stopped, whereas the high probability determination signal is the sound effect. When input to the generating means 58, the speaker 31 continues to generate a sound effect.

When the current probability is the normal probability, when the high probability determination signal is input to the sound effect generating means 58, the speaker 31 starts generating the sound effect, while the normal probability determining signal is changed to the sound effect generating means. When input to 58, the speaker 31 remains stopped generating the sound effect. After controlling the outputs of the lamp 30 and the speaker 31 in the step 77, as shown in FIG. 3, the process proceeds to step 78, and the winning probability probability setting step and the winning probability data corresponding to the number of games are selected.
Specifically, the probability selection means 54 (FIG. 1) is performed by selecting the lottery probability data from the winning probability data storage means 55 (FIG. 1).

After selecting the winning probability data in step 78, as shown in FIG. 4, the process proceeds to step 79, and it is determined whether or not the accessory continuous operation increasing device is in operation, that is, the "large bonus". It is determined whether or not. This determination is specifically carried out by the winning determination means 59 (FIG. 1). In the above step 79, if the accessory continuous operation increasing device is not in operation, that is, if it is not in “large bonus”, as shown in FIG. That is, it is determined whether or not the winning probability of a specific winning character is 10 times the normal probability, that is, a so-called “10 times winning character” state. This determination is specifically performed by the probability determination means 53 (FIG. 1).

When it is determined in the above step 80 that there is a high probability state, as shown in FIG.
Then, based on the high winning probability data, the state is set to a high probability, that is, a so-called “10 times winning character”. Specifically, the probability selection means 54 (FIG. 1) uses the high winning probability data from the winning probability data storage means 55 (FIG. 1), so-called “10”.
It is performed by sending the winning probability data of "double prize" to the winning determination means 59 (FIG. 1).

After setting the winning probability data in the step 81, the process proceeds to the step 82 as shown in FIG.
Lottery for "replay". Specifically, the lottery is performed by the winning lottery means 56 (FIG. 1) drawing one of the random number values generated by the random number generating means 52 (FIG. 1). After performing the "replay" lottery in step 82, the process proceeds to step 83 as shown in FIG. 4, and it is determined whether or not the lottery in step 81 corresponds to winning. Specifically, this determination is made by the winning determination means 59 (FIG. 1) and the probability selection means 54.

It is performed by drawing one of the random number values generated from 52 (FIG. 1). After the lottery of “1 cherry” is performed in the above step 84, as shown in FIG. 5, the process proceeds to step 85, and it is determined whether or not the lottery in step 83 corresponds to winning. This determination is specifically made by the winning determination means 59 (FIG. 1) based on the winning probability data signal from the probability selection means 54 (FIG. 1) and the lottery signal from the winning lottery means 56 (FIG. 1). To do.

In step 85, "1 cherry"
If the lottery is not a win, as shown in FIG. 5, the process proceeds to step 86 and the lottery of “2 cherry” is performed. Specifically, the lottery is performed by the winning lottery means 56 (FIG. 1) drawing one of the random number values generated by the random number generating means 52 (FIG. 1). In the above step 86, after the lottery of “2 cherries” is performed, as shown in FIG.
Then, it is judged whether or not the lottery in step 86 corresponds to winning. This determination is specifically made by the winning determination means 59 (FIG. 1) based on the winning probability data signal from the probability selection means 54 (FIG. 1) and the lottery signal from the winning lottery means 56 (FIG. 1). To do.

In step 87, "2 cherries"
If the lottery is not a win, as shown in FIG. 5, the process proceeds to step 88 and the lottery of “3 cherries” is performed. Specifically, the lottery is performed by the winning lottery means 56 (FIG. 1) drawing one of the random number values generated by the random number generating means 52 (FIG. 1). After the lottery of “3 cherries” is performed in the above step 88, as shown in FIG.
Then, it is determined whether or not the lottery in step 87 corresponds to winning. This determination is specifically made by the winning determination means 59 (FIG. 1) based on the winning probability data signal from the probability selection means 54 (FIG. 1) and the lottery signal from the winning lottery means 56 (FIG. 1). To do.

In step 89 above, "3 cherries"
If the lottery is not a win, as shown in FIG. 5, the process proceeds to step 90 and the "orange" lottery is performed. Specifically, the lottery is performed by the winning lottery means 56 (FIG. 1) drawing one of the random number values generated by the random number generating means 52 (FIG. 1). After the "orange" lottery is selected in step 90, the process proceeds to step 91 as shown in FIG. 5, and it is determined whether or not the lottery in step 89 corresponds to winning. This determination is specifically made by the winning determination means 59 (FIG. 1) based on the winning probability data signal from the probability selection means 54 (FIG. 1) and the lottery signal from the winning lottery means 56 (FIG. 1). To do.

If the "orange" lottery does not correspond to the winning in step 91, as shown in FIG.
Proceed to step 92, and draw a "lemon". Specifically, the lottery is performed by the winning lottery means 56 (FIG. 1) drawing one of the random number values generated by the random number generating means 52 (FIG. 1). In step 92 above, "lemon"
After the lottery, the process proceeds to step 93 as shown in FIG. 5, and it is determined whether or not the lottery in step 92 corresponds to winning. This determination is specifically made by winning determination means 59 (FIG. 1)
However, the determination is made based on the winning probability data signal from the probability selecting means 54 (FIG. 1) and the lottery signal from the winning lottery means 56 (FIG. 1).

When the "lemon" lottery does not correspond to the winning in step 93, the process proceeds to step 94, as shown in FIG. 6, whether or not the bonus game flag is established, that is, the so-called "JAC game". It is determined whether or not it is in progress. This determination is also specifically made by the winning determination means 59 (FIG. 1). In step 94 above, "J
When not in the "AC game", as shown in FIG. 6, the process proceeds to step 95, and the lottery probability of the winning character is selected by the setting mode. To make this selection, specifically, the probability selection means 54 (FIG. 1)
It is performed from the winning probability data input from the winning probability data storage means 55 (FIG. 1).

The setting mode has some patterns of a predetermined winning probability, and by changing this setting mode, the game store can freely adjust the way of medals. is there. In addition, here is the accessory
For example, "BAR, BAR, BA
"R" is aligned. After the setting mode is selected in the above step 95, as shown in FIG. Specifically, this lottery is performed by the winning lottery means 56 (FIG. 1) drawing one random number value out of the random number values sequentially generated from the random number generating means 52 (FIG. 1).

In the above step 96, after the lottery is selected,
As shown in FIG. 6, the routine proceeds to step 97, where it is judged whether or not the lottery result corresponds to winning. This determination is specifically carried out by the winning determination means 59 (FIG. 1). In the above-mentioned step 97, if not winning, as shown in FIG. 6, the process proceeds to step 98, and a lottery for whether or not to activate the accessory continuous operation increasing device, that is, a so-called "large bonus" lottery is performed. This determination is specifically carried out by the winning lottery means 56 (FIG. 1).

As a result of the lottery in the above step 98,
As shown in FIG. 6, the process proceeds to step 99, and it is determined whether or not the lottery result corresponds to winning. This determination is specifically carried out by the winning determination means 59 (FIG. 1).

That is, when the specific winning form is won, the rotating reels 11 to 13 are set so that the specific patterns of the rotating reels 11 to 13 are forcibly arranged on the predetermined lines 17 to 21. If you have not won, the specific picture on the rotating reel is
It is set to force exclusion so that it does not line up.

Further, when the above step 101 is carried out, the process advances to the next step, and this flowchart ends. In addition,
When it is determined in step 71 that the accessory continuous action increasing device is operating, that is, when the "large bonus" is being performed, the process proceeds to step 78 as shown in FIG. If it is determined in step 72 that the bonus game is being performed, the process proceeds from step 72 to step 102, and a small hit “kicking off” is performed. That is, the rotating reels 11 to 13 are controlled so that the patterns are not arranged in the winning form for the small hit.

Then, as shown in FIG.
The process proceeds from step 102 to step 103, and the "JAC game" is drawn. This lottery is specifically carried out by the winning lottery means 56 (FIG. 1). After the lottery in step 103, as shown in FIG. 3, the process proceeds to step 104, and it is determined whether or not the lottery result corresponds to winning. This determination is specifically performed by the winning determination means 59 (FIG. 1).

Then, if the result of the determination in step 104 is a win, as shown in FIG. 3, the process proceeds to step 105, and "JAC" is pulled in. That is, the patterns of "JAC" on the rotating reels 11 to 13 are forcibly set so as to be aligned on a specific line, here, the center line 17.
After the "JAC" pull-in is set in step 105, the process proceeds to step 101 as shown in FIG.

If the bonus game flag is established in step 73, the process proceeds from step 73 to step 78 as shown in FIG. When it is determined in step 75 that the lottery result in step 74 does not correspond to winning, the process proceeds from step 75 to step 78 as shown in FIG. When it is determined in step 79 that the accessory continuous operation increasing device is in operation, as shown in FIG.
Proceed to 107 and set the winning probability data for normal use while the accessory continuous operation increasing device is operating. That is, the winning probability data for the base game in the case where the "large bonus" game is not the "JAC game" is set.

Then, as shown in FIG.
The process proceeds from step 107 to step 108, and the "JAC game" is drawn. This lottery is specifically carried out by the winning lottery means 56 (FIG. 1). In step 108 above,
As shown in FIG. 4, as a result of the lottery result of the “JAC game”, the process proceeds to step 109, and it is determined whether or not the result corresponds to winning. This determination is also made specifically by the winning determination means 59.
(FIG. 1).

In step 109, as a result of the judgment,
When the “JAC game” is won, the process proceeds from step 109 to step 110, and the pulling of “JAC” is determined. Here, withdrawal of "JAC" means rotating reel 11
The pattern of "JAC" above 13 is forcibly drawn onto a specific line, here, the center line 17 to be aligned. Then, from step 110 to step 101,
The pull-in of "JAC" is actually set.

In step 80, the "10 times character product"
If it is determined that it is not in the middle, as shown in FIG. 4, the process proceeds from step 80 to step 111, and the winning probability data is set to the normal one. Then, the process proceeds from step 111 to step 82. If the result of the determination in step 83 above is a win, as shown in FIG. 4, the process proceeds from step 83 to step 112, and the replay pattern can be forcibly drawn onto the predetermined line 17-21. It is determined.

Then, as shown in FIG. 6, step 112
From step 101, the rotary reels 11 to 13 are set so that the replay patterns on the rotary reels 11 to 13 are actually aligned on the predetermined lines 17 to 21. If the result of determination in step 85 is a win, as shown in FIG. 5, the process proceeds from step 85 to step 113, and the "1 cherry" pattern is forcibly drawn onto the predetermined line 17-21. Is determined.

Then, as shown in FIG. 6, step 113
From step 101, the rotary reel 11 and the like are set so that the "1 cherries" on the rotary reels 11-13 are actually aligned with the predetermined lines 17-21. Further, in the above step 87, when the judgment result is a win, as shown in FIG.
Proceeding from step 87 to step 114, it is decided to forcibly draw the "2 cherry" pattern onto the predetermined lines 17-21.

Then, as shown in FIG. 6, step 114
From step 101, the rotary reels 11, 12 etc. are set so that the "2 cherries" on the rotary reels 11, 12 are actually aligned with the predetermined lines 17-21. Also, above step 89
In the case where the determination result is a win, in step 89, as shown in FIG. 5, the process proceeds from step 89 to step 115, and it is determined that the pattern of “3 cherry” is forcibly drawn onto the predetermined lines 17 to 21.

Then, as shown in FIG.
From step 101, the rotary reels 11 to 13 are set so that the "3 cherries" on the rotary reels 11 to 13 are actually aligned with the predetermined lines 17 to 21. Also, above step 91
In the case where the result of the determination is “win”, the process proceeds from step 91 to step 116 as shown in FIG.
It is decided to forcibly draw in the picture on the predetermined line 17-21.

Then, as shown in FIG.
To step 101, the rotary reels 11 to 13 and the like are set so that the "orange" on the rotary reels 11 to 13 is actually aligned with the predetermined lines 17 to 21. When the result of the determination in step 93 is a win, as shown in FIG. 5, the process proceeds from step 93 to step 117, and the "lemon" pattern can be forcibly drawn onto the predetermined lines 17-21. It is determined.

Then, as shown in FIG. 6, step 117
To Step 101, the rotary reels 11 to 13 and the like are set so that the "lemon" on the rotary reels 11 to 13 is actually aligned with the predetermined lines 17 to 21. In step 94 above,
If it is during the "JAC game", as shown in FIG. 6, the process proceeds to step 100, and the deviation is confirmed.

Then, as shown in FIG. 6, step 100
Then, the process proceeds to step 101, and "pull-in" or "kick-off" is actually set. Further, in the above step 97, when the determination result is a win, as shown in FIG.
Proceeding from step 97 to step 118, it is decided to forcefully draw the character design on the predetermined lines 17-21.

Then, as shown in FIG. 6, step 118
From step 101, the rotary reels 11 to 13 and the like are set so that the symbols on the reels 11 to 13 are actually aligned with the predetermined lines 17 to 21. Further, in the above step 99, when the determination result is a win, as shown in FIG.
Proceeding from step 99 to step 119, a specific pattern on which the accessory continuous operation increasing device operates, so-called "Seven, Seven,
It is decided that "Seven" will be forced to pull in on a given line 17-21.

Then, as shown in FIG.
From step 101, the rotating reels 11 to 13 and the like are set so that the specific pattern on the rotating reels 11 to 13, so-called "Seven, Seven, Seven", is actually aligned on the predetermined lines 17 to 21. As described above, in this embodiment, “1
