<p><P>PROBLEM TO BE SOLVED: To perform displaying by selecting an orbit pattern, which meets prescribed evaluation reference, such as passing an area in the neighborhood of a prize-winning port, in order to raise satisfaction of a player. <P>SOLUTION: It is determined whether or not the orbit of a game ball indicated by first orbit information which is generated in an orbit information generation step is a prize-winning orbit for prize-winning at a start prize-winning port. When the first orbit information is determined to be the prize-winning orbit, position relation between the game ball orbit indicated by the first orbit information and a specified prize-winning area is evaluated, and evaluation information of the first orbit information is generated. Previously stored evaluation information of the second orbit information is compared with evaluation information of the first orbit information generated in an orbit evaluation step. One of the kinds of orbit information is selected, based on the comparison result. When the first orbit information is selected, it is replaced with the second orbit information and its evaluation information, so as to store the first orbit information and its evaluation information. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
