<P>PROBLEM TO BE SOLVED: To provide a game machine having equality between players regardless of the level of the skill to understand the arrangement of nails and predict the movement of a game ball. <P>SOLUTION: The game machine includes: a unit 4302 for counting the number of game balls passing through a gate, wherein the unit counts the number of game balls passing through a gate; a mode shift unit 4326 for shifting a game to a potential high winning probability mode or small prize mode according to the result of a lottery performed by a lottery unit 4216; a unit 4301 for indicating a potential high winning probability, wherein the unit executes presentation indicating a potential high winning probability which indicates a high winning probability for a player during the potential high winning probability mode; and a unit 4303 for controlling the frequency of potential high winning probability, wherein the unit changes the execution frequency of the presentation indicating a potential high winning probability according to the counted value of the game balls passing through the gate. The probability of the passage of a game ball through the gate is substantially constant through game machines, so that when the execution frequency of the presentation indicating a potential high winning probability is changed according to the number of game balls passing through a gate, a similar number of game balls shot, equally performs the presentation indicating potential high winning probability at a similar frequency, even in a relatively advantageous game machine in which a game ball is easy to enter a start pocket or a relatively disadvantageous game machine in which a game ball is hard to enter a start pocket. <P>COPYRIGHT: (C)2013,JPO&INPIT |
