<P>PROBLEM TO BE SOLVED: To enhance the amusement of a game by allowing a player to freely receive the transition of difference numbers by which the situation of put-out balls can be easily recognized. <P>SOLUTION: A ball dispensing device 3 has a function of storing a difference number transition graph over a plurality of days with an ordinate axis as difference numbers (difference between safe balls and out balls) and an abscissa axis as times. If the player specifies any one date of the past in displaying the difference number transition graph of the day, the difference number transition graph of the day and the difference number transition graph of the past date selected by the player are superimposed on each other and displayed. As a result, the player can easily recognize the difference number transition of the day and the difference number transition of the past date optionally selected by the player by collating both transitions with each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
