Abstract

A method of triggering a multi-player game, comprising: determining a current number of eligible gaming machines; communicating current hit rate data based on the current number of eligible gaming machines to at least each eligible gaming machine; determining at each eligible gaming machine whether to trigger the multi-player game at a hit rate based on the current hit rate data.

First claim

The invention claimed is:

1. A method of gaming in a gaming system having a plurality of gaming machines, each gaming machine having a credit input mechanism configured to receive a physical item associated with a monetary value for establishing a credit balance, the credit balance being increasable and decreasable based at least on wagering activity, a display, and a feature controller, the method comprising:
establishing a credit balance via said credit input mechanism of a gaming machine, receiving the physical item;
in accord with having established the credit balance via the credit input mechanism receiving the physical item, starting via the feature controller a multi-player tournament game in which two or more players compete;
conducting via the feature controller game rounds for each of the two or more players until an end condition is met, each game round comprising, for each player:
(a) selecting via the feature controller a plurality of symbols for display at a plurality of display positions on the display associated with the player,
(b) determining via the feature controller if a designated symbol of the plurality of symbols is displayed amongst the symbols selected for display at the plurality of display positions, and
(c) in response to determining a said designated symbol is displayed amongst the symbols selected for display, increasing via the feature controller a total number of displayed designated symbols, and updating via the controller a player progress record from the displayed symbols of designated symbols;

determining via the feature controller at least one winning player when the end condition of obtaining a designated threshold of displayed designated symbols is met from a player's progress record; and
making via the feature controller an award to the winning player, wherein the award awarded to the winning player is derived at least in part from an amount initially wagered by the winning player and a time taken to obtain the designated threshold of designated symbols.

2. A method as claimed in claim 1 , wherein at least one player achieves an outcome.

3. A method as claimed in claim 2 wherein the outcome is that a designated number of designated symbols is reached by at least one of the players and wherein each player progress record stores a current number of designated symbols and in each game round, the player progress record is updated by determining a number of designated symbols for the round from the displayed symbols.

4. A method as claimed in claim 3 comprising, for each game round, visually representing each player's record by filling individual ones of a plurality of progress display positions corresponding to the designated total with the number of designated symbols determined for the game round.

5. A method as claimed in claim 2 , wherein the award is dependent at least partly on the time taken to achieve the outcome.

6. A method as claimed in claim 1 , wherein the end condition is that a designated number of game rounds is completed.

7. A method as claimed in claim 6 , wherein the award is based at least partly on the player's position based on the player progress record.

8. A method as claimed in claim 6 , wherein the award is based at least partly on a level achieved by the player by the completion of the designated number of game rounds.

9. A method as claimed in claim 1 , wherein display positions correspond to visible symbols of respective ones of a plurality of stopped reels and symbols selected for display for each reel.

10. A method as claimed in claim 9 , wherein each reel has a reel sequence and the symbols for each reel are selected by selecting a stop position for each reel sequence.

11. A method as claimed in claim 1 , wherein the game is started as a feature game in response to a trigger event, and the players play independently prior to the trigger event.

12. A method as claimed in claim 11 , wherein the trigger event is determined by determining a current number of eligible gaming machines;
communicating current hit rate data based on the current number of eligible gaming machines to at least each eligible gaming machine;
determining at each eligible gaming machine whether to trigger the multi-player tournament game at a hit rate based on the current hit rate data.

13. A method as claimed in claim 12 , wherein the eligible gaming machines are active gaming machines of a set of gaming machines.

14. A method as claimed in claim 12 , wherein the current hit rate data includes the current number of eligible gaming machines and each eligible gaming machine determines the hit rate from the number.

15. A method as claimed in claim 12 , wherein the current hit rate data is the hit rate.

16. A method as claimed in claim 12 , further comprising determining at each eligible gaming machine whether to trigger the multi-player tournament game as part of each game round.

17. A method as claimed in claim 11 , wherein the set of symbols from which symbols are selected are specific to the multi-player tournament game.

18. A method as claimed in claim 17 , wherein the symbols are comprised of the designated symbol and blank symbols.

19. A method as claimed in claim 11 , wherein each player plays a base game on the gaming machine and the trigger event occurs on the gaming machine of one of the players.

20. A method as claimed in claim 1 comprising controlling the game rounds with a tournament controller to ensure no player has an unintended advantage based on the number of game rounds played by each player.

21. A gaming system comprising:
a plurality of gaming machines, each gaming machine having a credit input mechanism configured to receive a physical item associated with a monetary value for establishing a credit balance, the credit balance being increasable and decreasable based at least on wagering activity, and a display, and said gaming machines being configured to, in accord with having established the credit balance via the credit input mechanism receiving the physical item, conduct a multi-player tournament game in which two or more players compete; and
a feature controller configured to:
start the multi-player tournament game in which two or more players compete;
conduct game rounds for each of the players until an end condition is met, each game round comprising, for each player:
(a) a selection of a plurality of symbols for display at a plurality of display positions on the display associated with the player,
(b) a determination of whether a designated symbol is displayed amongst the symbols selected for display at the plurality of display positions,
c) in response to determining that a said designated symbol is displayed amongst the symbols selected for display, an increase of a total number of displayed designated symbol, and an update of a player progress record from the displayed symbols of designated symbols;

determine at least one winning player when the end condition of obtaining a designated threshold of displayed designated symbols is met from a player's progress record; and
make an award to the winning player, wherein the award awarded to the winning player is derived at least in part from an amount initially wagered by the winning player and a time taken to obtain the designated threshold of designated symbols.

22. A gaming system as claimed in claim 21 , wherein the feature controller is further configured to conduct the game as a feature game in response to a trigger event occurring in relation
