The number of the coins inserted from thecoin insertion slot 27 or the bet operation using theoperation button 26 is detected respectively. - In S22, it is determined whether or not the start button is operated. That is, it is determined whether or not the start button is ON. The determination whether the start button is operated is executed based on whether the input signal is received from the start switch or not.
- If it is determined that the start button is not operated (S22: NO), the game returns to the start reception process. The operation such as correction of the bet number is possible at this time. On the other hand, if it is determined that the start button is operated (S22: YES), the bet number which is set is deducted from the credits owned by the player, and the subtraction result is stored in the
RAM 44 as the betting information. And then the game proceeds to S23. - In S23, the base game is progressed. In the base game, for example, the symbol rows are variably displayed on the symbol display portion, and then the symbol rows are stopped and displayed. Awards are provided based on the symbol combination of the symbols stopped and displayed. As the base game, various well-known games may be executed. And a predetermined award may be provided based on the game result. And then the game proceeds to S24.
- In S24, the winning probability is obtained. At this time, the
RAM 44 is referred. - In S25, the lottery of bonus is executed based on the obtained winning probability.
- In S26, it is determined whether the bonus is won or not. If it is determined that the bonus is not won (S26: NO), the main game process is terminated. If it is determined that the bonus is won (S26: YES), the game proceeds to S27.
- In S27, the payout process is executed. In the payout process, a predetermined number of gaming medium is paid out. Also the payout number of the gaming medium may be set appropriately.
- Next, the server base process executed in the
server 91 will be described.FIG. 1 is a flowchart of the server base process. The programs to execute the server base process are stored in theserver ROM 93 of theserver 91, and are executed by theserver CPU 92. - In S31, it is determined whether or not the payout rate information is received from any of the
slot machines 1. If it is determined that the payout rate information is not received from any of the slot machines 1 (S31: NO), the game returns to S31. In other words, the process will wait at S31 until the payout rate information is received from any of theslot machines 1. - On the other hand, if it is determined that the payout rate information is received from any of the slot machines 1 (S31: YES), the game proceeds to S32.
- In S32, the first table is renewed.
- The renewal of the first table will be described below.
-
FIG. 11 shows one example of the first table. InFIG. 11 , the slot machine having ID “0001”, the slot machine having ID “0002”, the slot machine having ID “0003”, and the slot machine having ID “0004” are connected to theserver 91. The payout rate in each slot machine is 85%, 95%, 90% and 80% respectively. Further, the winning probability of bonus in each slot machine is 0.015%, 0.005%, 0.010% and 0.020%. - Here, in the
slot machine 1, bonus may mean that to obtain predetermined amount of gaming media by extracting a random number value in a predetermined winning range (for example, 0 to 9) by lottery from a predetermined random number range (for example, 0 to 99999), to obtain predetermined amount of gaming medium by displaying a predetermined symbol combination is displayed on themain display 10B, or the like. The winning probability of the bonus can be changed by changing the winning range or by changing a probability of appearance of the predetermined symbol combination. - As shown in
FIG. 11 , the winning probability of bonus is set to be lower when the payout rate is higher. As the payout rate is higher, as the probability of the occurrence of the bonus is lower. - Further, the corresponding relationship between the payout rate and the winning probability of bonus shown in
FIG. 11 is only one of the examples. - The corresponding relationship between the payout rate and the winning probability of bonus in the first table is defined by the second table.
-
FIG. 12 shows one of the examples of the second table. InFIG. 12 , it shows that when the payout rate is below 80%, the winning probability of bonus is 0.025%, when the payout rate is 80% or more but below 85%, the winning probability of bonus is 0.020%, when the payout rate is 85% or more but below 90%, the winning probability of bonus is 0.015%, when the payout rate is 90% or more but below 95%, the winning probability of bonus is 0.010%, when the payout rate is 95% or more, the winning probability of bonus is 0.005%. As shown inFIG. 12 , the winning probability of bonus is set to be lower when the payout rate is higher. Further, the corresponding relationship between the payout rate and the winning probability of bonus shown inFIG. 12 is only one example. - The first table is renewed based on the received payout rate information and the second table. For example, when the payout rate information including the information “payout rate: 92%” is received from the
slot machine 1 having ID “0002”, since “92%” is in the range “90% or more but below 95%”, the winning probability of bonus for theslot machine 1 having ID “0002” becomes “0.010%”. As a result, in the first table, the winning probability of bonus for theslot machine 1 having ID “0002” is renewed to “0.010%”. -
FIG. 13 shows the content of the first table after renewal. - Now the description will be returned to
FIG. 1 . - In S33, the winning probability information is sent to the
slot machine 1 which sent the payout rate information in S31 based on the renewed first table. The new winning probability is included in the winning probability information. In aboveFIG. 13 , the winning probability information including “the winning probability: 0.010%” is sent to theslot machine 1 having ID “0002”. - According to the first embodiment described above, the
slot machine 1 sends the payout rate information to theserver 91 when the payout rate is changed. Theserver 91 renews the first table when the payout rate information is received from any of thelot machine 1. Here, in the first table, the payout rate of eachslot machine 1 is corresponding to the winning probability of bonus. And based on the content of the renewed first table, the winning probability information is sent to theslot machine 1 which sends the payout rate information. And after theslot machine 1 receives the winning probability information, the winning probability of bonus is renewed based on the winning probability information, and the lottery of bonus is executed based on the renewed winning probability of bonus. - As a result, the entertainment aspect is enhanced it can attract to players.
