<p>PROBLEM TO BE SOLVED: To protect a fair profit of a player by avoiding such a case that a ball passage of a specific area is invalidated by a factor unintended by the player.SOLUTION: When a game ball enters an operation-start hole to start a minor winning game, blade members of a first special electric generator are opened, a game ball distribution operation is executed inside the first special electric generator and, when a game ball passes through a specific area, a jackpot is produced. In that case, when a first error state (a magnetic error state, a vibration error state, or an electric wave error state) caused by a fraud is detected, the specific area is set to be invalidated (S232) and, when a second error state (a motor original point non-detection error state or the like) is detected, the specific area is set to be validated (S234). The second error state is not caused by an act of the player, but by an error state based on an incidental event such as ball clogging, so that the game machine sets to validate the specific area to give relief to the situation, thereby protecting the fair profit of the player.</p> |
