Gaming machine with multiple payoff modes and award presentation schemes

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 "winning" bid). A payoff is awarded based on the final winning bid.

  1. 1
    A slot machine comprising:a processor operable to select game outcomes in a first and second payoff mode;a display for displaying symbol groups associated with the game outcomes, each of the symbol groups comprising of a plurality of symbols displayed at a plurality of display positions;and symbol evaluation means for evaluating the symbol groups displayed in the first and second payoff modes, the symbol groups displayed in one of the first and second payoff modes being evaluated for symbol combinations displayed relative to one or more paylines and the symbol groups displayed in the other of the first and second payoff modes being evaluated for symbol combinations displayed in scatter-pay format.
  2. 10
    A method of operating a slot machine under control of a processor operable in a first and second payoff mode, the method comprising:selecting, under processor control, one or more game outcomes in the first payoff mode from a predefined set of possible outcomes, at least one of the possible outcomes defining a transition outcome;switching operation from the first payoff mode to the second payoff mode in response to the selection of a transition outcome in the first payoff mode;selecting, under processor control, one or more game outcomes in the second payoff mode from the set of possible outcomes used in the first payoff mode;displaying symbol groups associated with the game outcomes selected in the first and second payoff modes, each of the symbol groups comprising a plurality of symbols displayed at a corresponding plurality of display positions;and awarding credits based on the symbol groups displayed in the first and second payoff modes, the credits in the first payoff mode being based on symbols in the symbol group which are displayed relative to an active payline, the credits in the second payoff mode being based on all of the symbols in the symbol group.
  3. 11
    A method of operating a gaming machine under control of a processor, the method comprising the steps of:executing, under processor control, a bonus game program defining an award presentation;selecting, under processor control, a sequence of award values for said award presentation, the sequence of award values including an opening award value, a number of intermediate award values and a final award value;presenting the sequence of award values to a player;and awarding a payoff to the player based on the final award value.
  4. 21
    A gaming machine comprising:a processor operable to execute a bonus game program defining an award presentation;a selection element for selecting, under processor control, a sequence of award values for said award presentation, the sequence of award values including an opening award value, a number of intermediate award values and a final award value;a presentation element for presenting the sequence of award values to a player;and a payout mechanism for awarding a payoff to the player based on the final award value.
  5. 22
    A method of operating a gaming machine under control of a processor, the method comprising the steps of:executing, under processor control, a bonus game program defining an award presentation in which bids are made upon a selected object;selecting, under processor control, a sequence of the bids which are to be made in the award presentation, the sequence of bids including an opening bid, a number of intermediate bids and a final bid defining a winning bid;presenting the bids in the award presentation;and awarding a payoff to the player based on the winning bid.
  6. 36
    A gaming machine comprising:a processor operable to execute a bonus game program defining an award presentation in which bids are made upon a selected object;a selection element for selecting, under processor control, a sequence of the bids which are to be made in the award presentation, the sequence of bids including an opening bid, a number of intermediate bids and a final bid defining a winning bid;a presentation element for presenting the sequence of bids;and a payout mechanism for awarding a payoffto the player based on the winning bid.
  7. 39
    A gaming machine, comprising:a presentation element;and a processor causing said presentation element to successively present a non-linear increasing sequence of potential payouts to a player, said sequence of potential payouts being presented by said presentation element at irregular time intervals, at least a final one of said potential payouts being awarded to said player.
  8. 44
    A method of operating a gaming machine under control of a processor, comprising:providing a presentation element;successively presenting, on said presentation element, a non-linear increasing sequence of potential payouts to a player, said sequence of potential payouts being presented by said presentation element at irregular time intervals;and awarding at least a final one of said potential payouts to said player.
