<p>A poker game is simulatively played on a display device (34) every time a ball enters a specified prize-winning port (42). More specifically, prior to starting a single round of poker game, five cards are displayed on the display device in a lateral line in such a manner that four cards are placed face up and the fifth card is placed lying on its face. At the start of a single round of poker game, the fifth card is turned over face up. The number of opening and closing times or duration of opening or closing a variable prize-winning port (40) is modified depending upon a bonus point of a poker game. After the completion of a single round of poker game, the line of the five cards is laterally shifted one card to permit the front card to be discarded and a new card to be added at the other end with its face down, thus preparing for the next poker game.</p> |
