Filed: 2021-10-27
Abstract: PROBLEM TO BE SOLVED: To provide a game machine capable of enhancing a player's interest. 
     SOLUTION: The game machine includes: specific game state setting means which sets a specific game state where a second discrimination condition different from a first discrimination condition is easily established; second discrimination means which executes discrimination when the second discrimination condition is established; variable ball entry means capable of changing from a first state where game balls hardly make winning entry to a second state where the game balls easily make winning entry when identification information indicating a second discrimination result is displayed in display means as a result of discrimination by the second discrimination means; and a specific area through which the game balls making winning entry into the variable ball entry means can pass. Privilege game execution means executes a privilege game even when a game ball passes through the specific area. The specific game state setting means can set at least a first specific game state where the second discrimination condition is easily established and a second specific game state where the second discrimination condition is more hardly established than in the first specific game state. By this, the player's interest can be enhanced.

Title: Game machine
IPC: A63F7/02
Filed: 2021-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a game machine enabling efficient generation of energization force. 
     SOLUTION: Since a coil spring SP1 is positioned close to presentation means 780, energization force can be efficiently generated. Further, a player's visual recognition of the coil spring SP1 can be avoided by a spring cover SC1. It can be prevented that the spring cover SC1 makes symbols and patterns drawn on the exterior of the presentation means 780 invisible. Even if an unexpected posture change occurs in the presentation means 780, when the presentation means 780 is disposed at an ascended position, the spring cover SC1 contacts the presentation means 780 to correct the positional change. Therefore, positional changes can be corrected every time when disposed at the ascended position.
