Abstract

A programmable card handling machine with a display and appropriate inputs for adjusting the machine to any of a number of games comprises inputs including a number of cards per hand selector, a card game selector, a number of hands delivered selector and a trouble-shooting input. These features also provide for interchangeability of the apparatus for many different games, for many types of cards or decks and in different locations thereby reducing the number of back-up machines or units required at a casino. The display may include a game mode or game selected display, and use a cycle rate and/or hand count monitor and display for determining or monitoring the usage of the machine. The card-handling machine is capable of randomly selecting numbers of cards to be delivered in a hand of cards to players and the dealer during a round of a casino table card game.

Claims

1. An apparatus for providing hands of playing cards in a casino table card game comprising:

a playing card container;

a delivery tray;

a playing card moving system moving playing cards from the container to the delivery tray and forming a hand of playing cards in the delivery tray;

a processor containing software that directs the card moving system to randomly select how many playing cards will form the hand in the delivery tray.

2. The apparatus of claim 1 wherein the playing cards are moved individually by the playing card moving system to the delivery tray.

3. The apparatus of claim 1 wherein the playing cards are moved as a group by the playing card moving system to the delivery tray.

26. The apparatus of claim 1 further comprising a card shuffling mechanism that provides randomized cards to the container.

27. The apparatus of claim 26 wherein the card shuffling mechanism randomizes all cards prior to hand formation.

28. The apparatus of claim 26 wherein the card shuffling mechanism randomizes only a portion of cards prior to at least one hand being formed.

29. The apparatus of claim 26 wherein the card shuffling mechanism simultaneously randomizes cards and forms a hand of cards.

4. An apparatus for providing hands of playing cards in a casino table card game comprising:

a container receiving a first group of playing cards;

a playing card shuffling and playing card delivery system capable of forming random subsets of playing cards within the apparatus;

a playing card mover for moving the random subsets of playing cards to a delivery tray to form hands of playing cards; and

a processor controlling the card mover;

wherein the processor contains a program that randomly selects at least one variation from the group consisting of;

a number of playing cards in a hand of playing cards formed in the delivery tray, at least one hand in which a random number of playing cards will be provided, when random numbers of playing cards in at least one of player hands, common cards and a dealer hand is provided, whether at least one player hand or dealer hand will receive a random number of playing cards; and

a frequency at which random numbers of playing cards will be provided to at least one hand.

5. The apparatus of claim 4 wherein the program in the processor randomly selects a number of playing cards from within a defined range that will be provided to at least one hand in the casino table card game.

6. The apparatus of claim 4 wherein the program in the processor randomly selects a hand that is to contain a random number of playing cards.

7. The apparatus of claim 4 wherein the program in the processor randomly selects a hand that is to contain a random number of cards from within a predetermined range of numbers of playing cards.

8. The apparatus of claim 7 wherein the program in the processor allows only player hands to be selected to contain a random number of playing cards.

9. The apparatus of claim 7 wherein the program in the processor allows only a dealer'"'"'s hand to be number of playing cards selected to contain a random number of playing cards.

10. The apparatus of claim 7 wherein program in the processor allows only a hand to contain a random number of cards that is selected from the group consisting of a player'"'"'s hand, a dealer'"'"'s hand, community cards and both a player'"'"'s hand and dealer'"'"'s hand.

11. An apparatus for randomizing playing cards and forming hands of playing cards comprising:

a receiving area for a first set of playing cards;

a randomization area wherein the first set of cards is randomized;

a processor controlling playing card movement at least within the randomization area; and

a delivery tray where individual hands of playing cards are delivered or formed;

wherein a program in the processor randomly selects a number of playing cards to be delivered or formed within the delivery tray.

12. The apparatus of claim 11 wherein the program in the processor instructs the apparatus to form multiple hands wherein at least one hand has a card count unequal to card counts in at least one other hand.

13. The apparatus of claim 11 wherein the number of cards randomly selected is randomly selected from within a predetermined range.

14. The apparatus of claim 13 wherein only player hands are formed in or delivered to the dealing tray.

15. The apparatus of claim 13 wherein only player hands and dealer'"'"'s hands are formed in or delivered to the dealing tray.

16. A method of providing hands of playing cards for use in a casino table card game comprising:

randomizing a first group of cards within an apparatus; and

providing hands of a number of randomized cards for delivery to locations on a casino game table;

wherein the number of randomized cards is randomly determined.

17. The method of claim 16 wherein a number of randomized cards is randomly determined from within a predetermined number of cards.

18. The method of claim 16 wherein an underlying game play procedure in the casino table card game is played with players using a specific number of cards to form poker-type hands, and a random number of cards to be determined is selected from the group consisting of the specific number of cards, fewer than the specific number of cards, and more than the specific number of cards.

19. The method of claim 17 wherein an underlying game play procedure in the casino table card game is played with players using a specific number of cards to form poker-type hands, and a random number of cards to be determined is selected from the group consisting of the specific number of cards, fewer than the specific number of cards, and more than the specific number of cards.

20. The method of claim 18 wherein an underlying game play procedure in the casino table card game is played with players using a specific number of cards to form poker-type hands, and a random number of cards to be determined is selected from the group consisting of the specific number of cards and more than the specific number of cards.

21. The method of claim 20 wherein an underlying game play procedure in the casino table card game is played with players using a specific number of cards to form poker-type hands, and a random number of cards to be determined is selected from the group consisting of the specific number of cards and more than the specific number of cards.

22. The method of claim 16 wherein a randomized group of cards is formed within the apparatus and cards are delivered one at a time to a delivery tray to form individual hands.

23. The method of claim 16 wherein hands of random cards are formed within the apparatus and the hands of random cards are pushed onto a delivery tray.

24. The method of claim 23 wherein the hands pushed into a delivery tray are complete hands of cards.

25. The method of claim 23 wherein the bands pushed into the tray are partial hands of cards.

30. An apparatus for providing hands of playing cards in a casino table card game comprising:

a playing card container for a random group of playing cards;

a delivery tray;

a playing card moving system moving playing cards from the random group of playing cards container to the delivery tray and forming a hand of playing cards in the delivery tray;

a processor randomly selecting how many playing cards will form a hand in the delivery tray.
