PROBLEM TO BE SOLVED: To enable a game parlor to grasp the amount of a value added to a negotiable value whose magnitude can be specified by information stored on a storage medium. SOLUTION: A game can be played on a game machine by use of data about the balance of common use of the magnitude specified by information stored on an IC card and data about deposited balls. When the value whose magnitude matches the payment of the negotiable value owned by a player is added to the value whose magnitude is specified by the information stored on the storage medium, the total of the values (the sales of values for the game) is calculated.
