发明名称 System for implementing a secondary game
摘要 The present system provides an incentive for players to place maximum wagers in an effort to gain access to secondary games, the entry of which is controlled by the player's own wager amount, wager type, or wager source. In employing such games, gaming machine establishments are able to maximize the level of play on each of their gaming machines and thereby reduce operation costs and increase the number of machines available for play.
