Abstract

A gaming machine is described herein. The gaming machine includes a control unit programmed to initiate an instance of a primary game and spin and stop virtual reel strips to display an outcome of the primary game. The control unit detects an appearance of a winning combination of game symbols in the outcome and provides an initial award based on the winning combination, and detects an appearance of the collect symbol and a credit prize symbol in the outcome, determines an amount of credits associated with the credit prize symbol, and a bonus award including the determined amount of credits.

First claim

What is claimed is:

1. A gaming machine, comprising:
a cabinet;
a display device mounted to the cabinet; and
a game control unit including a processor programmed to execute an algorithm including the steps of:
displaying a game screen on the display device including a bonus credit meter displaying a credit balance and a plurality of virtual reels displaying a plurality of symbols within a plurality of cells arranged in a grid;
initiating an instance of a feature game by spinning and stopping the plurality of virtual reels to display an outcome of the feature game;
detecting one or more credit prize symbols appearing in the outcome of the feature game and responsively increasing the credit balance of the bonus credit meter based on an amount of credits associated with each of the one or more credit prize symbols appearing in the outcome of the feature game; and
detecting a reset symbol appearing in the outcome of the feature game and responsively resetting the bonus credit meter to an initial credit balance for use with a subsequent instance of the feature game.

2. The gaming machine of claim 1 , wherein the processor is programmed to execute the algorithm including the steps of:
detecting a collect symbol appearing in the outcome of the feature game and responsively increasing a primary credit meter a credit amount equal to the credit balance of the bonus credit meter.

3. The gaming machine of claim 2 , wherein the processor is programmed to execute the algorithm including the steps of:
resetting the bonus credit meter to the initial credit balance upon detecting the collect symbol appearing in the outcome of the feature game.

4. The gaming machine of claim 2 , wherein the processor is programmed to execute the algorithm including the steps of:
detecting an end symbol appearing in the outcome of the feature game and responsively terminating the feature game.

5. The gaming machine of claim 4 , wherein the processor is programmed to execute the algorithm including the steps of:
initiating another instance of the feature game if the end symbol does not appear in the outcome of the feature game.

6. The gaming machine of claim 4 , wherein the processor is programmed to execute the algorithm including the steps of:
detecting a mystery feature event symbol appearing the appearing in the outcome of the feature game and responsively selecting an event trigger symbol from a group of symbols including the collect symbol, the reset symbol, and the end symbol.

7. The gaming machine of claim 6 , wherein the processor is programmed to execute the algorithm including the steps of:
removing the mystery feature event symbol from the displayed outcome to reveal the selected event trigger symbol.

8. The gaming machine of claim 1 , wherein the processor is programmed to execute the algorithm including the steps of:
initiating the feature game upon detecting a triggering condition occurring with a primary game.

9. A method of operating a gaming machine including a display device mounted to a cabinet and a game control unit including a processor operably coupled to the display device, the method including the processor performing an algorithm including the steps of:
displaying a game screen on the display device including a bonus credit meter displaying a credit balance and a plurality of virtual reels displaying a plurality of symbols within a plurality of cells arranged in a grid;
initiating an instance of a feature game by spinning and stopping the plurality of reels to display an outcome of the feature game;
detecting one or more credit prize symbols appearing in the outcome of the feature game and responsively increasing the credit balance of the bonus credit meter based on an amount of credits associated with each of the one or more credit prize symbols appearing in the outcome of the feature game; and
detecting a reset symbol appearing in the outcome of the feature game and responsively resetting the bonus credit meter to an initial credit balance for use with a subsequent instance of the feature game.

10. The method of claim 9 , including the processor performing the algorithm including the steps of:
detecting a collect symbol appearing in the outcome of the feature game and responsively increasing a primary credit meter a credit amount equal to the credit balance of the bonus credit meter.

11. The method of claim 10 , including the processor performing the algorithm including the steps of:
resetting the bonus credit meter to the initial credit balance upon detecting the collect symbol appearing in the outcome of the feature game.

12. The method of claim 10 , including the processor performing the algorithm including the steps of:
detecting an end symbol appearing in the outcome of the feature game and responsively terminating the feature game.

13. The method of claim 12 , including the processor performing the algorithm including the steps of:
initiating another instance of the feature game if the end symbol does not appear in the outcome of the feature game.

14. The method of claim 12 , including the processor performing the algorithm including the steps of:
detecting a mystery feature event symbol appearing the appearing in the outcome of the feature game and responsively selecting an event trigger symbol from a group of symbols including the collect symbol, the reset symbol, and the end symbol.

15. The method of claim 14 , including the processor performing the algorithm including the steps of:
removing the mystery feature event symbol from the displayed outcome to reveal the selected event trigger symbol.

16. The method of claim 9 , including the processor performing the algorithm including the steps of:
initiating the feature game upon detecting a triggering condition occurring with a primary game.

17. A non-transitory computer-readable storage media having computer-executable instructions embodied thereon, when executed by at least one processor the computer-executable instructions cause the at least one processor to perform an algorithm including the steps of:
displaying a game screen on a display device including a bonus credit meter displaying a credit balance and a plurality of virtual reels displaying a plurality of symbols within a plurality of cells arranged in a grid;
initiating an instance of a feature game by spinning and stopping the plurality of reels to display an outcome of the feature game;
detecting one or more credit prize symbols appearing in the outcome of the feature game and responsively increasing the credit balance of the bonus credit meter based on an amount of credits associated with each of the one or more credit prize symbols appearing in the outcome of the feature game; and
detecting a reset symbol appearing in the outcome of the feature game and responsively resetting the bonus credit meter to an initial credit balance for use with a subsequent instance of the feature game.

18. The non-transitory computer-readable storage media of claim 17 , wherein the computer-executable instructions cause the at least one processor to perform the algorithm including the steps of:
detecting a collect symbol appearing in the outcome of the feature game and responsively increasing a primary credit meter a credit amount equal to the credit balance of the bonus credit meter.

19. The non-transitory computer-readable storage media of claim 18 , wherein the computer-executable instructions cause the at least one processor to perform the algorithm including the steps of:
detecting an end sy
