Abstract

Identifiers are read from playing cards collected after completion of at least one hand of a card game, such as blackjack, and the value of a hand is determined from the resulting sequence of read identifiers (i.e., ending sequence). The playing cards are collected in a defined order, such as from players in order from a dealer'"'"'s right to left, and finally from the dealer. The cards, and the play of the game, can be validated based at least in part on the ending sequence. Identifiers may also be read from cards before or while dealing the card game to produce an initial sequence.

Claims

1. A system for analyzing a card game played on a playing surface of a gaming table, the system comprising:

an optical reader operable to read an identifier from each of a number of playing cards collected after completion of at least one hand of at least one player of the card game to determine an ending sequence of playing cards;

detecting means for detecting a dealing of at least one playing card to the at least one hand of the at least one player, before determining the ending sequence of playing cards; and

means for automatically determining a value of the at least one hand based at least in part on the ending sequence and based at least in part on the detected dealing of at least one playing card to the at least one hand of the at least one player.

2. The system of claim 1 wherein the detecting means comprises at least one sensor positioned generally above the playing surface of the gaming table.

3. The system of claim 1 wherein the detecting means comprises at least one sensor positioned under the playing surface the playing table.

4. The system of claim 1 wherein the detecting means comprises at least one optical sensor.

5. The system of claim 1 wherein the detecting means comprises at least one camera.

6. The system of claim 1 wherein the detecting means comprises at least one camera positioned generally above the playing surface of the gaming table and operable to detect the appearance of each playing card dealt to the at least one hand of the at least one player.

7. The system of claim 1 wherein the detecting means comprises at least one optical source and receiver pair positioned below the playing surface of the gaming table, and operable to detect the appearance of each playing card dealt to the at least one hand of the at least one player.

8. The system of claim 1 wherein playing surface of the gaming table comprises a plurality of apertures formed therein, and the detecting means comprises a plurality of optical source and receiver pairs, positioned below the playing surface of the gaming table, and aligned with respective ones of the apertures, the optical source and receiver pairs operable to detect the appearance of each playing card dealt to the at least one hand of the at least one player.

9. The system of claim 1, further comprising:

means for determining an outcome of the card game based at least in part of the determined value of the at least one hand of the at least one player.

10. The system of claim 1, further comprising:

means for determining an initial sequence of playing cards corresponding to an order that the playing cards in a set of playing cards are dealt to at least one hand of at least one player in the card game.

11. The system of claim 10, further comprising:

means for determining whether a playing card has been inserted into the initial sequence of playing cards after the initial sequence has been determined.

12. The system of claim 11, further comprising:

means for determining whether a playing card has been removed from the initial sequence of playing cards after the initial sequence has been determined.

13. The system of claim 1, further comprising:

a receiver sized and dimensioned to receive and temporarily hold the playing cards collected after completion of the at least one hand of the at least one player of the card game.

14. The system of claim 1 wherein the optical reader comprises a scanner.

15. The system of claim 1 wherein the optical reader comprise an imager.

16. The system of claim 1 wherein the optical reader is a barcode reader.
