Title: Game machine
Inventor: UCHIGASHIMA TOSHIHIRO
IPC: A63F7/02
Filed: 2001-04-03
Abstract: PROBLEM TO BE SOLVED: To provide a game machine equipped with a lot redrawing function in which a winning is obtained with a probability varying pattern at the time of getting a big hit. SOLUTION: When a 'ready-to-win' condition is coming, the appearing rate of the normal pattern and the probability varying pattern is made approximately 3:1 so that the appearing rate of the normal pattern is heightened, and until an intra-'ready-to-win' condition redrawing is decided, a provisional stop is made with the normal pattern at a probability of approximately 3/4. After generation of the intra-'ready-to-win' condition redrawing, setting is made to the appearing probability of probability varying pattern (approximately 1/2). This is because the probability of the pattern at the time of 'ready-to-win' condition becoming a probability varying pattern is set to 1/2 in an ordinary model having no redrawing.  The appearing rate of the normal pattern and probability varying pattern is made approximately 1/2, and a provisional stop is made with the normal pattern at a probability of 1/2 approximately, and upon passing the intra-'ready-to-win' condition redrawing a grade-up is made to the probability varying pattern. That is, when intra-'ready-to-win' condition redrawing is generated, grade up to the probability varying pattern is made with a specified grade-up rate among the stop display with the normal pattern at the first time.
