A gaming system comprising an input device for placing wagers. The wagers include a first wager consisting of a base wager, and second and third wagers, each consisting of a base wager portion and an additional wager portion. The third wager has a higher ratio of the additional wager portion to the base wager portion than the second wager. An outcome is based on the first, second or third wager, such that upon said second wager being made and an designated event associated with the second wager occurring, a first additional benefit relative to when the first wager is made is provided, and upon said third wager being made and a designated event associated with the third wager occurring, a second additional benefit relative to when the first wager is made is provided. The second additional benefit is a greater benefit than the first additional benefit.
