Abstract
Certain embodiments provide a method and system for awarding a progressive prize. The system includes a bank of gaming machines accepting different bets per play as selected by a player. A random number is selected from a predetermined fixed range of numbers that does not change during play of a gaming machine. The player is allotted one or more numbers for each credit bet. The allotted numbers represent a subset of the predetermined fixed range of numbers. A feature game is triggered for the progressive prize based on a numerical comparison between the selected random number and the number(s) allotted to the player. Certain embodiments provide a trigger condition for a feature outcome based on an event having a probability related to credits bet per game at a gaming machine. A probability of success in the feature game may be higher than a probability of success in the base game.
