Abstract

A system which uses a specially coded deck of cards indicating the value and suit of the card or a value related to the count of the card as well as whether the card belongs to a particular set of cards senses the code on the card and sends the detected signal to a processor. The processor determines a running count, a betting count, a true count or other information related to the profitability of a particular wager or particular action, such as an insurance bet as well as an indication of whether the card belongs to the particular set of cards assigned to the table. The counts are displayed centrally and/or remotely from the shoe which dispenses the cards. The electronics for the system may be internally included as part of the shoe or externally included as a separate unit in which the shoe is secured.

Claims

1. An apparatus for determining at least one count during dealing of a set of playing cards, comprising:

means for holding said set of cards;

means for sensing a mark on each of said plurality of cards as each of said cards is dealt, said mark indicative of a value of each card and further indicative of said card belonging to said set;

means for incrementing said at least one count resulting in at least one accumulated count as each card is dealt; and

means for displaying said at least one accumulated count.

2. The apparatus of claim 1 wherein said mark is recorded optically and said means for sensing is an optical character reader.

3. The apparatus of claim 2 wherein said optically recorded mark is a bar code.

4. The apparatus of claim 2 wherein said optically recorded mark consists of existing card graphics.

5. The apparatus of claim 1 wherein said mark is encoded magnetically and said means for sensing is a magnetic scanner.

6. The apparatus of claim 1 further comprising:

means for signaling when one of said cards is sensed as not belonging to said set of cards.

7. The apparatus of claim 6 wherein said means for signaling generates an audible signal.

8. The apparatus of claim 6 wherein said means for signaling generates a visual signal.

9. The apparatus of claim 6 wherein said means for signaling is integral with said means for displaying.

10. The apparatus of claim 1 wherein said at least one accumulated count includes a running count, a betting count, a true count or other indicator of relative distribution of dealt cards.

11. The apparatus of claim 1 wherein said means for displaying is remotely located from said means for holding.

12. The apparatus of claim 1 wherein said means for incrementing and said means for displaying are remotely located from said means for holding.

13. An apparatus for determining at least one count continuously incremented during dealing of a set of cards, said apparatus comprising:

means for sensing a code on each card of said set and generating a signal for each card indicative of said code;

means for processing said signal to increment said at least one count relating to said cards which have been dealt resulting in at least one accumulated count indicative of relative distribution of said dealt cards; and

means for displaying said at least one accumulated count.

14. The apparatus of claim 13 further comprising:

means for signaling when a card is sensed not belonging to said set.

15. The apparatus of claim 13 wherein said card is optically recorded and said means for sensing is an optical character reader.

16. The apparatus of claim 15 wherein said optically recorded mark is a bar code.

17. The apparatus of claim 15 wherein said optically recorded mark consists of existing card graphics.

18. The apparatus of claim 13 wherein said code is magnetically recorded and said means for sensing is a magnetic scanner.

19. The apparatus of claim 14 wherein said means for signaling generates an audible signal.

20. The apparatus of claim 14 wherein said means for signaling generates a visual signal.

21. The apparatus of claim 13 wherein said means for displaying is remotely located from said means for sensing.

22. The apparatus of claim 13 wherein said means for displaying and said means for processing are located remotely from said means for sensing.

23. A method for calculating at least one count or other indication of relative distribution relating to playing cards dealt from a set of coded playing cards during a game of blackjack, the method comprising the steps of:

initializing said at least one count to establish an initial value for said at least one count;

sensing a code on each of said playing cards, said code indicative of a value of said card and whether said card belongs to said set;

generating a signal indicative of said sensed code;

processing said signal to increment said at least one count and providing an accumulated count for each of said at least one counts; and

displaying each of said accumulated counts.

24. The method of claim 23 further comprising the step of:

activating a signal when said sensed code indicates a card does not belong to said set.

25. The method of claim 23 wherein said code is optically recorded.

26. The method of claim 23 wherein said code is magnetically recorded.

27. The method of claim 25 wherein said optically recorded code is a bar code.

28. The method of claim 23 wherein said displaying is performed remotely from said sensing.

29. The method of claim 23 wherein said processing and said displaying are performed remotely from said sensing.

30. The method of claim 23 further comprising the step of:

removably holding said set of cards such that said sensing may be performed as each card of said set is being dispensed.
