PROBLEM TO BE SOLVED: To increase the anticipation for a bonus by determining the winning effective lines in response to the number of game mediums inserted in one game for each type of an winning generator in the game that winning is determined from a combination of stopped patterns on a plurality of pattern display windows and a prescribed number of game mediums are delivered. SOLUTION: Three reels are simultaneously rotated in three pattern display windows 131-133, then the rotation of corresponding reels is stopped via the action of stop buttons. When the combination of patterns stopped on an winning effective line determined by the number of inserted medals (and winning generator) is a prescribed winning combination, a number of medals corresponding to the type of winning are delivered. When 4+4+4=12 patterns can be displayed, big bonus winning effective lines are set to four horizontal lines + four diagonal lines = eight lines in all, regular bonus winning effective lines are set to two horizontal lines, and the winning effective lines for the other winning generator are set to four horizontal lines.
