Game System

Abstract

A game system includes a plurality of gaming machines and a server. Each of the gaming machines executes a game independently. When the server receives bet information, the server carries out a lottery for winning a progressive prize as to the gaming machine which transmitted the bet information. If any of the gaming machines wins any progressive prize, the server makes the gaming machine that has won the progressive prize to execute an effect for announcing winning of the prize. Meanwhile, the server makes the gaming machines other than the gaming machine that has won the progressive prize to conduct an effect for indicating losing of the prize.

1 . A game system comprising:
 a plurality of gaming machines each capable of executing a game independently; and   a server connected interactively to the plurality of gaming machines,   wherein each of the plurality of gaming machines comprises:

       3 . The game system according to  claim 1 ,
 wherein a processor provided in the server
 executes a lottery process for selecting one or a plurality of gaming machines from among the gaming machines other than any of the plurality of gaming machines having won the prize awarding the progressive payout, and 
 transmits the second effect signal to one or the plurality of gaming machines selected in the lottery process, at the process (d). 
   
   
   
       4 . The game system according to  claim 1 ,
 wherein the processor of each of the plurality of gaming machines
 executes the first effect by the effect device in conjunction with other gaming machines connected to the server, when receiving the first effect signal from the server at the process (c), and 
 executes the second effect by the effect device in conjunction with other gaming machines connected to the server, when receiving the second effect signal from the server at the process (d). 
   
   
   
       5 . A game system comprising:
 a plurality of gaming machines each capable of executing a game independently; and   a server connected interactively to the plurality of gaming machines,   wherein each of the plurality of gaming machines comprises:
 a bet operation portion for accepting a bet operation of a player; and 
 a processor that executes processes of:
 (A) transmitting bet information with respect to a bet amount betted through the bet operation portion to the server; 
 (B) executing a first stage lottery process for acquiring a winning right in respect of a prize awarding a progressive payout at a first winning probability set for each of the plurality of gaming machines; 
 (C) transmitting a lottery result of the first stage lottery process to the server; 
 (D) receiving a winning signal transmitted from the server; 
 (E) paying out, when receiving the winning signal from the server, a prize based on the winning signal received, and 
 
   wherein the server comprises:
 a memory storing a progressive payout at present; and 
 a processor that executes processes of:
 (a) adding to the progressive payout stored in the memory based on the bet information received from the plurality of gaming machines; 
 (b) obtaining the first winning probability set for each of the plurality of gaming machines as to the plurality of gaming machines; 
 (c) setting a second winning probability for each of the plurality of gaming machines based on the first winning probability set for each of the plurality of gaming machines; 
 (d) executing, when the lottery result of the first stage lottery process is received from a gaming machine among the plurality of gaming machines, as to which the first stage lottery process is executed, and the lottery result of the first stage lottery process received is acquiring of a winning right for the prize awarding the progressive payout a second lottery process for winning the prize awarding the progressive payout, to the gaming machine acquiring the winning right at the second winning probability set for the gaming machine; and 
 (e) transmitting, when the gaming machine acquiring the winning right wins the prize awarding the progressive payout, a winning signal including information with respect to the progressive payout amount stored in the memory based on a lottery result of the second stage lottery process. 
 
   
   
   
       6 . The game system according to  claim 5 , wherein, at the process (c), the processor provided for the server sets the second winning probability for each of the plurality of gaming machines for equalizing resultant winning probability of the plurality of gaming machines, each of resultant winning probability being a product of the first winning probability and the second winning probability set for each of the plurality of gaming machines. 
   
   
       7 . A game system comprising:
 a plurality of gaming machines each capable of executing a game independently; and   a server connected interactively with the plurality of gaming machines,   wherein each of the plurality of gaming machines comprises:
 a bet operation portion for accepting a bet operation of a player; and 
 a processor that executes processes of:
 (A) transmitting bet information with respect to a bet amount betted through the bet operation portion to the server; 
 (B) receiving a winning signal transmitted from the server; and 
 (C) paying out, when receiving the winning signal from the server, a payout amount based on information included in the winning signal; and 
 
   wherein the server comprises:
 a memory storing each of a plurality of progressive payouts at present; and 
 a processor that executes processes of:
 (a) adding to each of the plurality of progressive payouts stored in the memory based on the bet information received from the plurality of gaming machines; 
 (b) executing a lottery for winning a prize awarding a progressive payout as to the plurality of gaming machines; 
 (c) calculating a payout amount being modified from each progressive payout to be awarded among the plurality of progressive payouts stored in the memory, when two or more gaming machines among the plurality of gaming machines respectively win a prize awarding any one of the plurality of progressive payouts within a predetermined time lag; and 
 (d) transmitting a winning signal including information with respect to the payout amount calculated at the process (c) to each of the two or more gaming machines having respectively won a prize awarding a progressive payout. 
 
   
   
   
       8 . The game system of  claim 7 , wherein, at the process (c), the processor provided for the server calculates a payout amount, making the payout amount equal to each of the two or more gaming machines having respectively won the prize awarding the progressive payout within the predetermined time lag. 
   
   
       9 . The game system of  claim 7 ,
 wherein each of the plurality of gaming machines comprises
