Abstract: The present invention provides a wagering card game played with a standard fifty-two card deck of cards in which a dealer deals two cards to each of the players. The player must in turn choose whether to try to get one hit card that is numerically between the values of the two dealt cards or to get two hit cards that are above and below, respectively, the values of the two dealt cards. In either case, if the dealt cards constitute a pair, the player automatically loses. As dealt cards, aces are automatic loss cards and also are as hit cards unless assurance, a fee that allows an ace dealt as a hit card to be replaced by another hit card or to be put in play, depending on which option of the game the player has chosen to play, has been purchased.
