PROBLEM TO BE SOLVED: To reduce economic burden on a game hall introducing a game machine which allows a play using already gained points.SOLUTION: A CU (card unit) connected to a Pachinko machine (game machine) which allows a play using already gained points memorizes the number of game balls usable for games at the Pachinko machine. Information on the number of game balls increased in response to prize winning or the like and the number of game balls decreased in response to shot game balls is transmitted from the Pachinko machine to the CU every 200 ms. The CU which has received the information updates the number of game balls and memorizes it. When the Pachinko machine cannot receive an information transmission request even when 200 ms has elapsed, the Pachinko machine accumulates and memorizes the number of increased game balls and the number of decreased game balls until the next transmission request reaches. |
