Abstract

Card shuffler apparatuses include a card repositioner used to randomly reposition a plurality of cards on-edge over an aperture extending through a card support surface to allow cards to sequentially pass through the aperture in a random order. The apparatuses may be capable of continuously and sequentially forming playing card hands for use in a game. Shuffler apparatuses may be used to obtain a measurement relating to a thickness of the deck of cards. Methods involve the use of card shuffler apparatuses to form one or more playing card hands in a playing card game. Additional methods involve counting playing cards present within a stack of playing cards using a shuffler apparatus. In further methods, a number of shuffler apparatuses and a lesser number of shuffler activation devices are provided in a gaming establishment so as to preclude simultaneous use of all the shuffler apparatuses in the establishment.

Claims

1. A method of using a plurality of shuffler apparatuses within a gaming establishment, comprising:

providing a first number of shuffler apparatuses in the gaming establishment, each shuffler apparatus of the first number of shuffler apparatuses comprising a receptacle for receiving an activation device therein, operation of each shuffler apparatus of the first number of shuffler apparatuses being precluded when an activation device is not received within the receptacle; and

providing a second number of activation devices in the gaming establishment, the second number being less than or equal to the first number.

2. The method of claim 1, wherein each shuffler apparatus of the first number of shuffler apparatuses comprises:

a card support surface for supporting a plurality of cards thereon, the card support surface having an aperture extending through the card support surface for allowing cards of the plurality of cards to pass through the card support surface;

a repositioner for receiving and supporting the plurality of cards over the card support surface, the repositioner configured to randomly reposition the plurality of cards over the aperture extending through the card support surface to allow one or more cards of the plurality of cards to sequentially pass through the aperture in a random order; and

a card collector for sequentially receiving the one or more cards of the plurality of cards therein as they pass sequentially through the aperture and form a plurality of shuffled cards in the card collector.

3. The method of claim 1, wherein the second number is less than the first number.

4. A method of operating a card shuffler configured to permit operation thereof when an activation device is inserted in a receptacle of the shuffler and configured to disable operation when the activation device is not inserted in the receptacle, the method comprising:

inserting an activation device in the receptacle to enable operation of the card shuffler.

5. The method of claim 4, wherein inserting an activation device in the receptacle comprises inserting a radio frequency activation device into the receptacle.

6. The method of claim 4, wherein the activation device comprises a key, and wherein the key comprises a radio frequency identification device embedded therein.

7. A card shuffler, comprising:

a card support surface for supporting a plurality of cards thereon, the card support surface having at least one aperture extending through the card support surface for allowing cards of the plurality of cards to individually pass through the card support surface;

a repositioner for receiving and supporting the plurality of cards over the card support surface, the repositioner configured to randomly reposition the plurality of cards over the at least one aperture to allow cards of the plurality of cards to individually pass through the at least one aperture in a random order;

a body defining a receptacle for an activation device; and

a controller configured to permit operation of at least a portion of the card shuffler when the activation device is present within the receptacle and configured to disable operation of at least a portion of the card shuffler when the activation device is absent from the receptacle.

8. The card shuffler of claim 7, wherein the controller is configured to permit operation of the repositioner when the activation device is present within the receptacle and configured to disable operation of the repositioner when the activation device is absent from the receptacle.

9. The card shuffler of claim 7, wherein the controller is configured to transmit a signal to at least one positioner actuator.

10. The card shuffler of claim 9, wherein the controller is configured to cause the at least one aperture to be unblocked by signaling the at least one positioner actuator to remove at least one playing card from the at least one aperture when the activation device is present within the receptacle and configured to cause the at least one aperture to be blocked by signaling the at least one positioner actuator to place at least one playing card in the at least one aperture when the activation device is absent from the receptacle.

11. The card shuffler of claim 7, further comprising an exciter configured to vibrate the cards over the card support surface.

12. The card shuffler of claim 11, wherein the controller is configured to control the operation of the exciter.

13. The card shuffler of claim 7, wherein the controller is configured to control the operation of a card receiver actuator.

14. The card shuffler of claim 7, wherein the controller is operably coupled to a card receiver sensor.

15. The card shuffler of claim 7, wherein the controller is configured to control the operation of at least one aperture actuator.

16. The card shuffler of claim 15, wherein the controller is configured to cause the at least one aperture to be opened when the activation device is present within the receptacle and configured to cause the at least one aperture to be closed when the activation device is absent from the receptacle.

17. The card shuffler of claim 15, wherein the controller is configured to cause the at least one aperture to be unblocked when the activation device is present within the receptacle and configured to cause the at least one aperture to be blocked when the activation device is absent from the receptacle.

18. The card shuffler of claim 15, wherein the controller is configured to cause the at least one aperture to be opened by signaling the at least one aperture actuator to open at least one gate when the activation device is present within the receptacle and configured to cause the at least one aperture to be closed by signaling the at least one aperture actuator to close the at least one gate when the activation device is absent from the receptacle.

19. The card shuffler of claim 7, wherein the controller comprises a receiver adapted to detect a radio frequency signal.

20. The card shuffler of claim 7, further comprising:

a housing defining an opening through which cards may be inserted into the card shuffler; and

a card collector configured to receive cards as the cards pass through the card shuffler.
