Title: Roll object control method of pachinko machine
Inventor: KITATSUME HIDETO
IPC: A63F7/02
Filed: 2000-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a roll object control method for a pachinko machine which achieves a control so as to keep players from estimating any jackpot figure and the number of rounds in the operation of roll objects due to the figure. SOLUTION: With the display of a jackpot figure on a special figure display device (S1), a roll object is operated by a roll object control means (S9). The frequency of continuous operation of the roll object is determined by lottery in a system being separated from the jackpot figure (S2 to S8). As a result, players can not estimate the number of rounds from the combination of the jackpot figures to prevent the players from 'estimating limited number of rounds eventually losing desire for game' at the pre-winning stage. This helps players enjoy game feeling expectation to the end of the game. The separate arrangement of the round lottery makes the ratio in the lottery of the number of rounds optional without interfering the jackpot figure thereby easily enhancing game enjoyment.
