Abstract

Embodiments of the present invention are directed to gaming devices and methods for implementing mystery bonus results in place of base game results on a gaming display. The gaming device comprises a base game having a base game display. A random number generator is optionally operable with the base game to obtain a base game result, and the base game display operative to display the base game result. A base game pay table is tied to the base game result and includes winning outcomes and non-winning outcomes. A bonus game award mechanism is configured to determine a threshold tied to a bonus result, track play of the base game, advance a counter responsive to play at the base game, display the bonus result at the base game display in place of the base game result when the counter bears a predefined relationship with the threshold, and award a bonus to a player.

First claim

The invention claimed is:

1. A gaming device comprising:
a base game having a base game display;
a bill acceptor associated with the gaming device for receiving and validating one of a bill and a ticket received at the acceptor;
a credit meter on the gaming device, the credit meter being operable to display credits available for play when the one of a bill and ticket is received;
a random number generator operable with the base game to obtain a base game result for each play of the base game, each result comprising a combination of symbols that may be a winning result or a losing result, the base game display operative to display the base game result on a result display;
a counter configured to count the number of base game results to a predefined threshold;
a bonus result comprising a winning combination of symbols generated independently from the base game results determined by the random number generator;
a delay circuit for delaying display of the bonus result until the next non-winning result produced by the base game if the base game result that advanced the counter to the predefined threshold is a winning result;
a bonus game award mechanism configured to display the bonus result on the result display in place of and substituting for the next non-winning result produced by the base game after the threshold is reached and award a bonus to a player;
a ticket printer associated with the gaming device; and
a ticket issued by the ticket printer reflecting the balance of credits that remain on the gaming device.

2. The gaming device of claim 1 , wherein the gaming device includes a plurality of bonus results including at least one bonus result that does not match any base game result possible on the base game.

3. The gaming device of claim 1 , the result display including indicia locations and wherein the bonus game award mechanism is configured to display an indicia at one of the indicia locations that is unavailable in any base game outcome.

4. The gaming device of claim 3 , wherein the indicia locations include three reel positions and a final one of the reel positions for the bonus result is a -7-, wherein the final -7- indicia is unavailable in the base game outcome.

5. The gaming device of claim 1 , further including:
a player tracker with player record; and
wherein the threshold is set according to criteria stored in the player record.

6. The gaming device of claim 5 , wherein the threshold is set differently for players having different player records.

7. The gaming device of claim 1 , wherein the gaming device includes a plurality of base games, the counter being further configured to track play of the plurality of base games and advance a count responsive to play at the plurality of base games, the result display displaying a bonus result at a particular one of the plurality of base games in place of and substituting for the base game result at that particular one of the plurality of base games.

8. The gaming device of claim 1 , wherein the gaming device is configured to allow play by a plurality of players, the counter being further configured to track play by the plurality of players and advance a count responsive to play by the plurality of players, the result display displaying a bonus result to a particular one of the plurality of players in place of and substituting for a base game result obtained by that particular player.

9. The gaming device of claim 8 , wherein the plurality of players form a group selected according to a common player profile.

10. The gaming device of claim 1 , wherein the random number generator is integrated within the base game.

11. The gaming device of claim 1 , wherein the random number generator is external of the base game.

12. The gaming device of claim 1 , wherein the bonus game award mechanism is integrated within the base game.

13. The gaming device of claim 1 , wherein the bonus game award mechanism is external of the base game.

14. The gaming device of claim 1 wherein the threshold comprises a number randomly selected from within a predefined range of numbers.

15. The gaming device of claim 14 wherein the counter is configured to determine a plurality of thresholds each tied to a different bonus result.

16. The gaming device of claim 15 wherein each threshold comprises a number randomly selected from within a predefined range of numbers.

17. The gaming device of claim 16 wherein at least two of the numbers are randomly selected from within different predefined ranges of numbers.

18. The gaming device of clam 17 wherein the predefined range of numbers for one bonus result is at least two orders of magnitude greater than the predefined range of numbers for another bonus result.

19. The gaming device of claim 1 wherein the gaming device further includes a plurality of spinnable reels each having a plurality of symbols thereon and wherein the combinations of symbols are made up of at least one symbol from each of at least two of the reels.
