<p><P>PROBLEM TO BE SOLVED: To provide a game machine which can increase the amusement of a game by increasing the game property during a specified game status. <P>SOLUTION: This game machine is equipped with a big winning port 11, a shift controlling means, and a round controlling means. In this case, the big winning port 11 changes between an ease of winning in which a game ball is easy to enter, and a winning difficult state in which the game ball is hard to enter. The shift controlling means makes the game status shift from a normal game status to a specified game status. The round controlling means repeatedly executes a round control which switches the game status to the difficulty of winning after placing the big winning port 11 under the ease of winning in the specified game state with a specified number of times as the upper limit. Under the winning easy state, when a fact that the game ball has entered the big winning port 11 is detected, the success/failure of the switching condition is judged from a specified judgement probability, and when the establishment of the switching condition is judged, a control for switching the big winning port 11 from the ease of winning to the winning difficult state is executed. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
