PROBLEM TO BE SOLVED: To provide a game machine which can sufficiently thrill and excite the player in a shortened time mode. SOLUTION: A shortened time mode is started when a shortened time starting display mode different from a special premium appeared as the result of a first display game regarded as a slot machine. Thereby ball holding is kept better until the next special premium. The continuation time of the shortened time mode is regulated by time regardless of the number of execution of the second display game and the continuation time is changed corresponding to the kind of a shortened time starting mode when the first display game appeared. The upper limit number of balls dischargeable per unit time is increased than that in an ordinary time during the shortened time mode. |
