Abstract

An apparatus and method for automatically switching between any of a plurality of theoretical expectations on a gaming or amusement device of the kind where the outcome is determined by a combination of random or pseudo-random events yielding an associated score from a table of values. Any one of a plurality of predetermined random "trigger" events will cause the amusement or gaming device to automatically vary the likelihood of certain random events, without altering the associated score for any particular outcome, for a minimum "duration" period. By altering the likelihood of any particular outcome, the device will operate at a different theoretical expectation.

Claims

1. An apparatus for automatically varying multiple theoretical expectation on a gaming device;

comprising in combination;

processing means including an associated memory means;

said processing means operatively coupled to at least one gaming device;

a default representation mode of at least one said gaming device stored in said memory means;

an incentive representation mode of at least one said gaming device stored in said memory means;

means for providing a trigger event;

said processing means responding to said trigger event by changing said default representation mode to said incentive representation mode of at least one said gaming device whereby multiple theoretical expectation on at least one said gaming device is varied; and

means for concealing the current game representation mode from a player for subliminally offering greater excitement to the player.

2. The apparatus of claim 1 wherein said incentive representation mode of at least one said gaming device is maintained for a duration period and based on an incentive representation pay table.

3. The apparatus of claim 2 wherein said processing means includes means for changing said incentive representation mode based on said incentive pay table to said default representation mode based on a default representation pay table separate and distinct from said incentive representation pay table when said duration period has ended.

4. A method for automatically varying multiple theoretical expectations on a gaming device, comprising the steps of:

providing a power source,

providing a processing means operatively coupled to the gaming device and to the power source,

providing a memory means associated with the processing means and including a default representation pay table and a separate incentive representation pay table of the gaming device stored therein,

starting a game on the gaming device when a start of game event occurs,

determining the occurrence of a trigger event;

enabling the incentive representation pay table of the gaming device when the occurrence of the trigger event has been determined; and

concealing the current gaming device representation from a player for subliminally offering greater excitement to the player at random intervals.

5. The method of claim 4 including the step of communicating a signal from the processing means to the gaming device for performing a reset game mode operation when the power source is activated.

6. The method of claim 5 including the step of performing a wait for event operation.

7. The method of claim 6 including the step of determining when an event has occurred.

8. The method of claim 7 including the step of distinguishing what event has occurred.

9. The method of claim 8 including the step of providing a game counter in communication with the processing means.

10. The method of claim 9 including the step of determining if the game counter is enabled upon the occurrence of the start of game event.

11. The method of claim 10 including the step of determining if said game counter is greater than zero upon the occurrence of the start of game event.

12. The method of claim 11 including the step of decrementing the game counter when the game counter is greater than zero.

13. The method of claim 12 including the step of providing a timer in communication with the processing means.

14. The method of claim 13 including the step of setting said timer to a maximum duration if the trigger event has occurred.

15. The method of claim 14 including the step of performing a wait for event operation after play of game has ended.

16. The method of claim 15 including the step of powering down said device if an event has occurred which is not the start of game event or a wager event.

17. The method of claim 16 including the step of determining if the game counter is enabled when the wager event occurs.

18. The method of claim 17 including the step of evaluating said game counter when the wager event occurs.

19. The method of claim 18 including the step of decrementing the game counter if the game counter reveals a count greater than zero.

20. The method of claim 19 including the step of returning to said wait for event operation when the wager event occurs and after said game counter is decremented.

21. The method of claim 20 including the step of performing said reset game mode operation if the game counter reveals a count less than or equal to zero.

22. The method of claim 21 including the step of determining if the trigger event has occurred when the game counter is not enabled.

23. The method of claim 22 including the step of starting the play of game after the game counter is determined to be disabled and trigger event has not occurred.

24. An apparatus for automatically varying multiple theoretical expectation on a gaming device;

comprising in combination;

a processing means including an associated memory means;

said processing means operatively coupled to said gaming device;

means for identifying a particular player operatively coupled to said gaming device;

a first representation mode of said gaming device stored in said memory means;

a second representation mode of said gaming device stored in said memory means;

means for providing a trigger event correlative to the particular player identified;

said processing means responding to said trigger event by changing said first representation mode to said second representation mode of said gaming device whereby multiple theoretical expectation on said gaming device is varied.

25. The apparatus of claim 24 wherein said first representation mode is a default mode having a winning hit rate on a default pay table which coincides with a long term expectation.

26. The apparatus of claim 25 wherein said second representation mode is an impoverished mode having a winning hit rate on a impoverished pay table which is separate and less than said winning hit rate on said default pay table.

27. The apparatus of claim 26 wherein said impoverished mode is maintained for a duration period once said trigger event has occurred.

28. The apparatus of claim 25 wherein said second representation mode is an incentive mode having a winning hit rate on an incentive pay table which is separate and greater than said winning hit rate on said default pay table.

29. The apparatus of claim 28 wherein said incentive mode is maintained for a duration period once said trigger event has occurred.

30. The apparatus of claim 24 wherein said means for identifying a particular player includes a card reader operatively coupled to said gaming device and a player card particular to the player scanned by said card reader.

31. The apparatus of claim 24 wherein said means for identifying a particular player includes means for automatically identifying a new player by using said processing means for monitoring an elapsed period of time between games played and comparing playing speeds between a current player and a previous player.

32. An apparatus for automatically varying multiple theoretical expectation on a gaming device;

comprising in combination;

a processing means including an associated memory means;

said processing means operatively coupled to said gaming device;

a plurality of representation modes of said gaming device stored in said memory means;

said plurality of representation modes including a default mode, an incentive mode and an impoverished mode;

means for providing a trigger event;

said processing means responding to said trigger event by changing one said representation mode to another said representation mode of said gaming device whereby multiple theoretical expectation on said gaming device is varied.

33. The apparatus of claim 32 wherein said plurality of representation modes includes said default mode having a winning hit rate for a pay table which coincides with a long term expectation.

34. The apparatus of claim 33 wherein said plurality of representation modes further includes said incentive mode having a winning hit rate for said pay table which is greater than said winning hit rate in said default mode.

35. The apparatus of claim 34 wherein said plurality of representation modes further includes said impoverished mode having a winning hit rate for said pay table which is less than said winning hit rate of said default mode.

36. The apparatus of claim 35 wherein said trigger event means includes a first trigger event which prompts said processing means to change said default mode to said incentive mode representation of said gaming device.

37. The apparatus of claim 36 wherein said trigger event means includes a third trigger event which prompts said processing means to change said default mode to said impoverished mode representation of said gaming device.
