Abstract

Claims (36)

1. An electronic gaming system comprising:

at least one electronic video display device;

at least one input device;

at least one memory device;

at least one wager accepting device configured to accept a physical item associated with a monetary value to increase a credit balance on the electronic gaming system; and

at least one processor configured to receive a plurality of instructions from the at least one memory device, which when executed by the at least one processor, cause the at least one processor to:

(a) determine a wager from the credit balance placed by a player of the electronic gaming system;

(b) cause the at least one electronic video display device to display primary game symbols in association with primary symbol positions defined by a plurality of primary reels;

(c) determine if a secondary game is triggered, wherein the secondary game is triggered when the at least one display device displays a plurality of matching primary game symbols;

(d) upon determining that the secondary game is triggered:

(1) cause the at least one electronic video display device to display one or more secondary reels in place of a subset of said primary symbol positions, said secondary reels displaying a plurality of secondary game symbols;

(2) determine a secondary game outcome based solely upon said displayed secondary game symbols; and

(e) award at least one secondary game award for one or more winning secondary game outcomes.

2. The electronic gaming system of claim 1 wherein the number of secondary reels is greater or less than the number of primary reels corresponding to said subset of primary symbol positions.

3. The electronic gaming system of claim 1 wherein said plurality of secondary game symbols is greater or lesser in number than the number of primary game symbols in said subset of primary symbol positions.

4. The electronic gaming system of claim 1 wherein said at least one processor causes a periphery of an area of said plurality of primary reels containing said at least one subset or primary symbol positions to be highlighted if the secondary game is triggered.

5. The electronic gaming system of claim 1 wherein said secondary game is triggered when the at least one display device display a plurality of matching primary game symbols in a first subset of primary symbol positions and said secondary reels are displayed in place of a second subset of primary symbol positions.

6. The electronic gaming system of claim 1 wherein said secondary reels display a plurality of secondary symbol positions and secondary game symbols are displayed in at least some of said secondary symbol positions.

7. The electronic gaming system of claim 1 wherein said at least one processor awards at least one primary game award based upon a winning combination of primary game symbols.

8. A method of presenting a wagering game via an electronic gaming system comprising:

(a) receiving a physical item associated with a monetary value at a wager accepting device of the electronic gaming system, a credit balance at the electronic gaming system being increased by the monetary value, and determining a wager from the credit balance placed by a player of the electronic gaming system;

(b) causing at least one electronic video display device to display primary game symbols in association with primary symbol positions defined by a plurality of primary reels;

(c) determining if a secondary game is triggered, wherein the secondary game is triggered when the at least one display device displays a plurality of matching primary game symbols;

(d) upon determining that the secondary game is triggered:

(1) causing the at least one electronic video display device to display one or more secondary reels in place of a subset of said primary symbol positions, said secondary reels displaying a plurality of secondary game symbols;

(2) determining a secondary game outcome based solely upon said displayed secondary game symbols; and

(e) awarding at least one award for one or more winning secondary game outcomes.

9. The method of claim 8 wherein the number of secondary reels is greater or less than the number of primary reels corresponding to said subset of primary symbol positions.

10. The method of claim 8 wherein said plurality of secondary game symbols is greater or lesser in number than the number of primary game symbols in said subset of primary symbol positions.

11. The method of claim 8 further comprising highlighting a periphery of an area of said plurality of primary reels containing said at least one subset or primary symbol positions if the secondary game is triggered.

12. The method of claim 8 wherein said secondary game is triggered when the at least one display device display a plurality of matching primary game symbols in a first subset of primary symbol positions and said secondary reels are displayed in place of a second subset of primary symbol positions.

13. The method of claim 8 wherein said secondary reels display a plurality of secondary symbol positions and secondary game symbols are displayed in at least some of said secondary symbol positions.

14. The method of claim 8 wherein said subset of primary symbol positions comprises primary symbol positions associated with at least M primary reels and said step of causing the at least one electronic video display to display one or more secondary reels comprises displaying N secondary reels, wherein N is greater than M.

15. The method of claim 8 wherein said step of causing the at least one electronic video display device to display one or more secondary reels in place of a subset of said primary symbol positions comprises displaying said one or more secondary reels in an area of said primary reels corresponding to said subset of primary symbol positions.

16. The method of claim 8 comprising displaying said one or more secondary reels in a spinning condition while said primary game reels are fixed.

17. The method of claim 8 further comprising awarding at least one primary game award for one or more winning combinations of said primary game symbols.
