Abstract

A gaming system comprises a wager input device receiving a wager from a player to play a wagering game, at least one display, and at least one controller. The wagering game provides access to a progressive game having multiple progressive jackpots. The multiple progressive jackpots are reset after being awarded. In response to a progressive jackpot being awarded, a current expected value of the wagering game is calculated with a normal reset value applied to the awarded progressive jackpot. And, in response to the calculated current expected value of the wagering game being less than a minimum jurisdictional limit, the awarded one of the multiple progressive jackpots is reset with a padded reset value so that the expected value of the wagering game is equal to or greater than the minimum jurisdictional limit. The padded reset value is greater than the normal reset value.

Claims

1. A gaming system, comprising:

a wager input device for receiving a wager from a player to play a wagering game, the wagering game providing access to a progressive game having multiple progressive jackpots, the multiple progressive jackpots capable of being reset after being awarded to a player;

at least one display to display a randomly selected outcome of the wagering game and to display information related to the progressive game; and

at least one controller operative to;

contribute at least a portion of the wager to the multiple progressive jackpots;

in response to one of the multiple progressive jackpots being awarded, calculate a current expected value of the wagering game with a normal reset value applied to the awarded one of the multiple progressive jackpots; and

in response to the calculated current expected value of the wagering game being less than a minimum jurisdictional limit, reset at least the awarded one of the multiple progressive jackpots with a padded reset value so that the expected value of the wagering game is equal to or greater than the minimum jurisdictional limit, the padded reset value being greater than the normal reset value.

2. The gaming system of claim 1, wherein the information related to the progressive game includes award values for each of the multiple progressive jackpots.

3. The gaming system of claim 2, wherein the at least one controller is coupled to the display, the at least one controller instructs the display to display the padded reset value for the awarded one of the multiple progressive jackpots.

4. The gaming system of claim 1, wherein the at least one controller is further operative to calculate the padded reset value so that the expected value of the wagering game is equal to or greater than the minimum jurisdictional limit.

5. The gaming system of claim 4, wherein the at least one controller is further operative to calculate the padded reset value so that the expected value of the wagering game is substantially equal to the minimum jurisdictional limit.

6. The gaming system of claim 1, wherein, in response to the current expected value being lower than the minimum jurisdictional limit, the controller is further operative to reset another one of the non-awarded progressive jackpots from a current jackpot award value to a second padded reset value so that the expected value of the wagering game is equal to or greater than the minimum jurisdictional limit, the second padded reset being greater than the current jackpot award value for the non-awarded progressive jackpot.

7. The gaming system of claim 1, wherein each of the multiple progressive jackpots has a predetermined padded reset value for use by the at least one controller.

8. The gaming system of claim 1, wherein the wagering game includes a base game and the progressive game, the expected value of the wagering game being the summation of the expected values of the base game and the progressive game.

9. The gaming system of claim 1, wherein the gaming system includes progressive-game controller for controlling the progressive game and a gaming terminal for playing the wagering game, the gaming terminal having a gaming-terminal controller, the at least one controller including the gaming-terminal controller and the progressive-game controller.

10. The gaming system of claim 1, wherein the controller is further operative to, in response to the calculated current expected value being equal to or greater than the minimum jurisdictional limit, reset the awarded progressive jackpot to the normal reset value.

11. A method of conducting a wagering game on a gaming system, the wagering game including a base game and a progressive game having multiple progressive jackpots, the method comprising:

awarding, via at least one controller, one of the multiple progressive jackpots to a player;

after the awarding, calculating, via the at least one controller, the current expected value of the wagering game with a predetermined reset value for the value of the awarded progressive jackpot; and

in response to the calculated current expected value of the wagering game being less than a minimum limit, resetting, via the at least one controller, at least the awarded progressive jackpot to a padded reset value to cause the expected value of the wagering game to be equal to or greater than the minimum limit, the padded reset value being greater than the predetermined reset value.

12. The method of claim 11, further including displaying, on a display, values for each of the multiple progressive jackpots including the padded reset value after the resetting.

13. The method of claim 12, wherein the wagering game is conducted on a gaming terminal, and the displaying occurs on a display associated with the gaming terminal.

14. The method of claim 11, further including, prior to resetting the awarded progressive jackpot to the padded reset value, calculating the padded reset value so that the expected value of the wagering game is equal to or greater than the minimum limit.

15. The method of claim 11, wherein the wagering game includes a base game, at least one bonus game associated with the base game, and the progressive game, the expected value of the wagering game being the summation of the expected values of the base game, the at least one bonus game, and the progressive game.

16. The method of claim 11, wherein each of the multiple progressive jackpots has a predetermined padded reset value for use by the controller.

17. The method of claim 11, wherein the minimum limit is a jurisdictional minimum limit.

18. A method of conducting a wagering game on a gaming system, the wagering game including a base game and a progressive game having multiple progressive jackpots, the method comprising:

receiving, from wager-input devices, wager inputs for the wagering game from players;

allocating a portion of the wager inputs to the progressive game so as to increase award values of the multiple progressive jackpots;

awarding, via at least one controller, one of the multiple progressive jackpots to a player;

after the awarding, calculating, via the at least one controller, the current expected value of the wagering game with a normal reset value for the value of the awarded one of the multiple progressive jackpot; and

in response to the calculated current expected value of the wagering game being less than a minimum limit, adjusting, via the at least one controller, one of either an award parameter of the base game or the normal reset value of the awarded one of the progressive jackpots so as to cause the expected value of the wagering game to be equal to or greater than the minimum limit.

19. The method of claim 18, wherein the base game includes a plurality of winning outcomes, each of the plurality of winning outcomes including an associated award value, and wherein the adjusting of the award parameter of the base game is increasing the associated award value for one of the plurality of winning outcomes.

20. The method of claim 18, wherein the base game includes a plurality of winning outcomes, and wherein the adjusting of the award parameter of the base game includes adding an additional winning outcome to the base game.

21. The method of claim 20, wherein the wagering game is a slot gamine having a plurality of reels within a display region, the additional winning outcome is an additional scatter symbol that provides an award when appearing within the display region.

22. The method of claim 18, wherein the adjusting of the normal reset value includes switching the normal reset value to a padded reset value that has a predetermined value.

23. The method of claim 18, wherein the adjusting of the normal reset value includes switching the normal reset value to a padded reset value, the padded reset value being a value that is calculated by a controller, the padded reset value causing the expected value of the wagering game to be equal to or greater than the minimum limit.

24. The method of claim 18, further including displaying, on a display, values for each of the multiple progressive jackpots including the padded reset value after the adjusting.

25.
