发明名称 Ticket drawing games having escalating discrete prize levels
摘要 Ticket drawings having escalating discrete prize levels within a gaming environment are provided. A gaming system having an automated random ticket drawing game module provides ticket drawing bonus games in conjunction with primary wager based games. Ticket drawings can include base, intermediate and ultimate prize levels, with each level corresponding to a specific prize and range of ticket entries. The prize level escalates as more ticket entries are granted. Ticket entries can be awarded for various events, such as a 3-of-a-kind at a primary wager based game. Drawings include a time period for the acceptance of ticket entries, including a predefined start and end. Award and drawing mechanisms and multiple display devices facilitate each drawing. Multiple drawings can occur simultaneously, such as an hourly and daily drawing. Drawings may also be part of an ongoing series of continuous ticket drawings, such as 24 hourly drawings in a given day.
