  • Method of playing blackjack game
    Patent number: 5454570
    Abstract: An improved game of blackjack allows the player to insure against the appearance of values of cards in a dealer's hand which would defeat the numerical value of a player's hand and cause the player to lose the original wager. If the wagered on value appears, the player is paid according to predetermined odds. The player will win or lose the original wager according to conventional blackjack rules. The improved game allows the player to sequentially insure against a winning dealer's hand in light of sequentially changing game conditions.
