Abstract

A system for monitoring the play at gambling games is disclosed. The preferred embodiment comprises a system for monitoring the play at blackjack as that game is played in casinos. The system typically will comprise video monitor means for generating a digital representation of the bets made by the players and of the cards dealt to the players and to the dealer, so that an output can be generated indicating whether the correct payouts are made and bets collected. An alarm signal is generated if an error is made in the play of the game. An alarm signal may also be generated if the long-term statistics of the game indicate that the odds ordinarily applicable to the game have been departed from over a period of time.

Claims

1. A system for monitoring the play of a gambling game of chance, the outcome of which depends on the outcome of a random physical occurrence, comprising:

means for determining the bets placed by each player;

means for optically monitoring the outcome of said random occurrence;

means for determining whether each player has won or lost his bet at the termination of each round of play;

means for determining whether each player'"'"'s bet has either been correctly paid out or collected from him;

means for determining whether conditions exist which would tend to alter the odds ordinarily applicable to the game being played; and

means for generating an alarm signal in the event that an error is made in the play, such that the rules of the game are broken, or that such conditions exist;

wherein said means for determining the bets placed and said means for optically monitoring comprise means for analyzing an optical image formed by a video camera and for generating a numeric representation thereof.

2. The system of claim 1 further comprising means for examining the play of cards, where the game being played is a card game, and means for recognizing the values of cards dealt to players and correlating those values with individual players.

3. The system of claim 2 wherein said system correlates said players and the cards dealt to them by examining specific areas assigned to each player at his card location on a playing table.

4. The system of claim 1 wherein said means for determining the result of each player'"'"'s bet and for generating an alarm signal comprises digital computer means.

5. A system for monitoring the play of a blackjack game comprising:

optical scanner means for generating a digital representation of the bets made by players and of the cards dealt to them and to the dealer; and

digital computer means for storing the output of said optical scanner means, for calculating the proper result of each hand played and for generating an alarm when an error is made in the play of the hands, said computer means further being adapted to output an alarm signal when the play of a sequence of hands indicates that a statistical imbalance exists in the values of the cards having been played, so as to alter the odds ordinarily applicable to the game.

6. The system of claim 5 wherein said system recognizes bets made by players and cards dealt to them by assigning individual areas on the playing table to individual ones of said players.

7. The system of claim 5 wherein plural computers each monitoring play at a single table are adapted to have their outputs summed so as to enable generation of a report summing over plural ones of said playing tables.

8. Method for monitoring the play at gambling games, the outcome of which depends on one or more random physical events, comprising the steps of:

detecting the bet made by each player with video camera means and associating it with that player;

optically detecting the occurrence of said one or more random physical events with video camera means;

generating digital signals corresponding to said bets and the occurrence of said random physical events as detected by said video camera means;

at the conclusion of each round of play, calculating the outcome of each player'"'"'s bet responsive to said signals;

determining whether the payout to the players and the collection of their bets is made by a dealer in accordance with the rules of the game; and

generating an alarm if said determination indicates that said rules have been violated.

9. The method of claim 8, comprising the additional step of retaining the outcome of plural rounds of play at a particular table, and generating an alarm if said outcome indicates that the odds ordinarily applicable to the game have varied.
