Abstract
A slot machine with multiple payoff modes and award presentations. The payoff modes in one embodiment are associated with a basic game and include a first and second payoff mode, the second payoff mode defining a “SUPER SCATTER” feature. Game outcomes are selected in the first and second payoff mode and symbol groups associated with the game outcomes are evaluated in the first payoff mode for symbol combinations displayed relative to one or more paylines and in the second payoff mode for symbol combinations displayed in scatter-pay format. In one embodiment, the machine operates in the first payoff mode until the occurrence of a symbol combination triggering the second payoff mode, then operates in the second payoff mode for a single spin before returning to the first payoff mode. The award presentations include a non-linear sequence of award values which in one embodiment are associated with a bonus game characterized by characters bidding upon a selected object that may be presented in irregular time intervals. The sequence of award values (bids) including a first value (“opening bid”), a number of intermediate values (bids) and a final value (a “win…
