<p><P>PROBLEM TO BE SOLVED: To enable early detection of occurrence of a failure and to perform control in the failure appropriately according to a game state in an enclosed ball type game machine. <P>SOLUTION: Based on detection results by a first detection means and a second detection means, it is determined whether a difference between a game ball discharged to a game area 27 and a game ball that has passed through collection parts (each winning hole, out hole 145, and foul ball return hole 150) has reached a threshold for determination in the failure, and control in the failure is executed. Also, the threshold for determining the failure is changed according to a game state (during an in-jackpot game, a change to thresholds ("25", "35") for in-jackpot is performed). <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
