  • Patent number: 5785606
    Abstract: A multiple hand variation of the card game Twenty-One involving individual players being dealt five cards, the five cards being divided into a two-card hand and a three-card back hand is disclosed. In a first embodiment of the invention, the cards are arranged into a two-card hand that comes as close to twenty-two points as possible, and into a three-card hand made up of the remaining cards. The two-card hand, which is the better of the two hands, is designated as the "front" hand and is positioned in front of the other hand, which is designated the "back" hand. In the event that the back hand exceeds twenty-two points, ten points are automatically subtracted from the back hand to prevent a "bust" from occurring with regard to that hand. In a second embodiment of the invention, the player has the option of maximizing either the two-card hand or the three-card hand to a predetermined point level.

  • Patent number: 5294128
    Abstract: A multiple hand variation of the card game of Hi-Lo poker involving individual players being dealt six cards, the six cards being divided into a one-card high ranking hand, a two-card high ranking hand, and a three-card low ranking hand is disclosed. The cards in the three hands are ranked according to a hierarchy which ranks individual cards according to values placed upon each card and in addition, ranks combinations of cards according to an established criteria. The players must arrange the cards in the three hands so as to maximize their overall chances of having one or more winning hands when compared to a bank player's three hands. Each player's one-card, two-card and three-card hands are compared against the bank player's respective one-card, two-card and three-card hands to determine if the player wins the hand in which case the bank player pays the player, or if the player loses the hand, in which case the player forfeits its wager for the hand, or there is a tie.
