ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to casino table and electronic-format card games such as Poker, Blackjack and Baccarat.
BACKGROUND
Card games such as Poker and Baccarat are well known forms of casino-type games. They provide excitement and entertainment to the players. In these games the players are looking for a game in which they have a reasonable chance of winning their wager and the casinos are looking for a reasonable return for hosting the game.
Baccarat is one of the many live table games played in casinos or gaming establishments. Baccarat uses a standard deck of fifty-two playing cards and is usually dealt from a shoe having multiple decks that have been shuffled together prior to the beginning of play.
The object of the game of Baccarat is for the bettor to successfully wager on whether the Bank's hand or the Player's hand is going to win. The bettor receives even money for his wager if he selects the winning hand and loses his wager if he selects the losing hand. Because of the rules of play of Baccarat, and more particularly the pre-established draw rules, the Bank's hand has a slightly higher chance of winning than does the Player's hand. The winning frequency for the Bank's hand has been determined to be 0.45859 (45.859%) whereas the winning frequency for the Player hand is 0.44624 (44.624%) with the remainder of the outcomes being ties. Therefore, if the bettor wagers on the Bank's hand and the Bank hand wins, the bettor must pay to the gaming establishment a commission (typically, 5%) of the amount the bettor wins. No commission is paid if the bettor successfully wagers on the Player's hand.
As used in this specification, the term “Conventional Manner of Play of Baccarat” is as follows:
A multiple number of decks of standard playing cards, 52 in number, are used; typically eight decks are shuffled together and placed in a shoe from which the cards are dealt during the play of the game.
Each bettor makes a wager on whether the Bank's hand or the Player's hand will win. After all wagers are made, two cards are dealt from the shoe to the Bank position and two cards are dealt from the shoe to the Player position on the table layout. The cards are turned face up and the value of the Bank hand the Player hand is determined, modulo ten.
Aces count one; Kings, Queens, Jacks and Tens count zero and the other cards count their respective face value. The suits (Spades, Hearts, Diamonds and Clubs) have no meaning in Baccarat.
The highest hand value in Baccarat is nine. All hand values range from a low of zero to a high of nine. If when the cards are added together, the total of the hand exceeds nine, then the hand value is determined modulo ten. For example, a seven and a eight total fifteen, but the hand value is five. An Ace and a nine total ten, but the hand value is zero.
A two card total of eight or nine is called a “natural”; a two card total of zero is called a “baccarat.” As will be explained below, in certain situations in the play of the game, a third card will be dealt. The value of this third card is added to the total of the first two cards and a new hand value is established. Again, if the new hand total exceeds nine, the hand value is determined by subtracting ten from the total of the hand.
Prior to the deal, each better can make one of three wagers: 1) that the Bank hand will win; 2) that the Player hand will win; or 3) that the Bank hand and the Player hand will tie. Wagering locations are provided on the Baccarat table layout. Whichever of the Bank hand or the Player hand is closest to a total of nine is the winner.
All winning Bank hand wagers are paid off at odds of one-to-one and the house charges a five percent (5%) commission on the amount won by the bettor. For example, if a bettor wagers $100 on the Bank hand and the Bank hand wins, the bettor wins $100 and is charged a $5 commission on the amount that the bettor won. The bettor is not charged any commission on the amount of his wager.
All winning Player hand wagers are paid off at odds of one-to-one and the bettor is not charged any commission on the amount of his winnings or his wager because the house, by virtue of the third card draw rules, has a statistical advantage over the player of 45.859−44.624 or 1.235% which is the vigorish (“vig”) of the house on player wagers. Winning wagers on the Tie hand bet are paid off at odds of nine-to-one or eight-to-one (depending on the gaming establishment) and the bettor is not charged any commission on the amount of his winnings or his wager since there is already a statistical advantage in favor of the house on tie wagers. If a Tie hand occurs, all wagers on the Bank hand and all wagers on the Player hand are “pushes” and the amount wagered is returned to the bettor.
Depending on the point total of the Player's hand and the Dealer's hand, one more card may be dealt to either the Player's hand, the Dealer's hand or both. The rules for determining whether a third card is dealt are fixed; that is, there is no discretion for either the Player's hand or the Dealer's hand on whether a third card is dealt.
If either the Player hand or the Dealer hand has a point total of eight or nine on the first two cards, no third card is dealt to either hand and the hand with the highest point total is the winner (or a Tie, as the case may be). If neither the Player hand nor the Dealer hand has a point total of eight or nine, then there is a possibility of a third card draw.
The third card draw rules are as follows:
Rule #1: If the initial two card Player hand has a point total of 0, 1, 2, 3, 4 or 5, the Player hand draws a third card. If the initial two card Player hand has a point total of 6 or 7, the Player hand stands and does not receive a third card.
Rule #2: If the Player hand stands and does not draw a third card, then the Bank hand follows Rule #1. In other words, if the Player hand has a point total of 6 or 7, the Bank hand draws a third card on a point total of 0, 1, 2, 3, 4 or 5 and the Bank hand stands on a point total of 6 or 7.
Rule #3: If the Player hand draws a third card, the Bank hand must draw or stand as follows:

At the end of each hand, winning wagers are paid and losing wagers are collected by the house. Any commission due to the house is marked in commission boxes in the center of the table. Gaming chips are used to represent the amount of money owed by each bettor to the house for the commissions. In order not to slow down the game, the commission is not actually collected from each bettor until the end of the round determined by all of the cards in the shoe being dealt down to the plastic cut card, usually approximately eighty hands.
The mathematical analysis of the game reveals that the 5% commission is what gives the house its advantage on wagers on the Banker hand and allows the gaming establishment to make a profit from providing the Baccarat game to the bettors. Because the rules for standing and drawing third cards are automatic, the mathematical analysis shows that the Bank hand will win 45.859% of the hands, the Player hand will win 44.624% of the hands and the Tie hand will occur 9.517% of the hands.
