Abstract

A secure game table system, adapted for multiple sites under a central control, for monitoring each hand in a live card game. A common deck identity code is located on each card. A shuffler has a circuit for counting the cards from a previous hand which are inserted into the shuffler and which reads the common identity code. The game control verifies that no cards have been withdrawn from the hand by a player or that new cards have been substituted. A unique code also placed on each card is read as the card is dealt to indicate the value and the suit. The game control stores this information in a memory so that a history of each card dealt is recorded. Sensors are located near each of the player positions for sensing the presence of a game bet and a progressive bet. A card sensor located near each player position and the dealer position issues a signal for each card received. The game control receives these signals and correlates those player positions having placed a game and/or progressive bet with the received cards. The game control at each table has stored in memory the winning combinations necessary to win the progressive jackpots. Since the game control accurately stores the suit and value of each card received at a particular player position, the game control can automatically detect a winning progressive combination and issue an award signal for that player position.
