Abstract

A method and apparatus for determining the win or loss of individual participants in a game of chance, such as for example Black Jack, Poker or the like, wherein the bet and the winnings are represented by chips. A central chip depository is provided for receiving the game inventory and the latter has means for determining its momentary content. At least one chip deposit area is provided per participant and has in each case at least one sensor for the detection of chips lying on the deposit area. The means for determining the momentary chip content and also the sensors have their outputs connected to the inputs of a data processing system.

Claims

1. A method for determining the total amount bet by individual players participating in a plurality of hands of a game of chance that uses cards at a gaming table having betting areas for each player on which the players place the gaming chips they wish to bet for each hand, with the cards being dealt by a dealer and with a gaming chip depository being provided at the gaming table, the method comprising the steps of:

detecting the start of each new hand,

detecting whether or not each individual player has placed a bet in each respective hand by detecting the presence of at least one gaming chip representing the bet on the respective betting area associated with each individual player,

detecting the total value of gaming chips present in said gaming chip depository,

determining which individual players have lost a hand at a first stage of the hand,

collecting the bets of individual players who have lost at the first stage of the hand and placing the bets individually in the gaming chip depository,

identifying the size of each bet individually placed in the gaming chip depository by determining the change in value of the gaming chip depository,

associating the size of this bet with the respective betting area, and thus with the player,

counting the total number of hands played by the player,

and estimating a total amount bet by that player by mathematically linking an average amount bet by the individual player with the total number of hands he has played, wherein the average amount bet is determined based upon each bet individually placed in the gaming chip depository corresponding to that individual player.

2. A method in accordance with claim 1 including the step of storing information relating to the placement of bets on the betting areas and all changes relating to the inventory in the gaming chip depository in a data processing system and associating time signals with any such changes.

3. A method in accordance with claim 1, wherein the start of each new hand is detected by detecting the placement of bets by at least some of the players and by detecting the placement of cards by the dealer on a card area associated with the dealer.

4. A method in accordance with claim 2 in which the shuffling of cards is detected by rapid changes of an output signal of a card sensor associated with the dealer'"'"'s card area and inhibiting the processing of information relating to the betting areas during card shuffling.

5. A method in accordance with claim 1, wherein a winning area is associated with each player and the placement of winnings on the win area by the dealer is detected and used to evaluate the winnings of each player by linking the number of times gaming chips are placed on the winning area with the average amount bet by the player and taking account of the relationship of the amount won to the amount bet as determined by the rules of the game.

6. A method in accordance with claim 1 including the further steps of supplying information relating to non-dependant game filling changes in the inventory of the gaming chip depository via a dealer operated keyboard.

7. A method in accordance with claim 1 including the further step of determining the performance of the dealer from information stored in the data processing system at the start of gaming and during the playing of a plurality of hands, e.g. by determining the average duration of a hand, the number of hands played per hour and the time spent shuffling cards.

8. A method for determining the total amount bet by individual players participating in a plurality of hands of a game of chance that uses cards at a gaming table having betting areas for each player on which the players place the gaming chips they wish to bet for each hand, with the cards being dealt by a dealer and with a gaming chip depository being provided at the gaming table, the method comprising the steps of:

detecting the start of each new hand,

detecting whether or not each individual player has placed a bet in each respective hand by detecting the presence of at least one gaming chip representing the bet on the respective betting area associated with each individual player,

detecting the total value of gaming chips present in said gaming chip depository,

determining which individual players have lost a hand,

collecting the bets of individual players who have lost a hand and placing the bets individually in the gaming chip depository,

identifying the size of each bet individually placed in the gaming chip depository by determining the change in value of the gaming chip depository,

associating the size of this bet with the respective betting area, and thus with the player,

counting the total number of hands played by the player,

and estimating a total amount bet by that player by mathematically linking an average amount bet by the individual player with the total number of hands he has played, wherein the average amount bet is determined based upon each bet individually placed in the gaming chip depository corresponding to that individual player.
