<p>PROBLEM TO BE SOLVED: To provide a technique capable of reducing a risk of probability variation blowout when a player puts in an unfortunate situation.SOLUTION: After termination of a special game, when a game ball passes through a specific area during a special round game, a game machine sets a lottery probability related to an internal lottery to a high probability state where a player acquires a win at a high probability compared with that of a low probability state where the player acquires a win at least a normal probability in the internal lottery. However, when no game ball passes through the specific area during the special round game, the game machine sets the lottery probability related to the internal lottery to the low probability state, and, when it is checked that no game ball passes through the specific area from when the special round game is started in a state where the game ball can pass through the specific area until a specific time elapses, executes a rescue performance with a content instructing that the lottery probability related to the internal lottery is not set to the high probability state unless a game ball passes through the specific area during the special round game.</p> |
