<P>PROBLEM TO BE SOLVED: To prevent the amusement of a game from becoming monotonous by varying an expectation degree given to a player from time to time without fixing it to one kind. <P>SOLUTION: Even for a probability variable jackpot or an ordinary jackpot of different round numbers, an opening/closing pattern of a big winning port is set the same, and thus, although the same movement is generated apparently when winning the jackpot, an indication lamp or the like informs in which round the jackpot occurs. Therefore, it is difficult to determine, from the number of times of the opening of the big winning port, in which round the jackpot is obtained. Here, expectation degrees for both probability variations are mixed, the player determines the round number by utilizing the information through the indication lamp or the like and can enjoy to guess the expectation degree for the probability variation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
