Abstract: An improved double down wager for blackjack involves offering the player a split double option. The split double option may be either in lieu of, or in addition to, a standard double down option. Originally, when a player elects a split double option, the player places a wager increase to the initial wager. The dealer then deals the player n additional cards. Each of the cards is separately used in combination with the initial cards to form a separate player final hand. The total wager is likewise divided into individual wagers for each player final hand so constructed. Each player final hand is then evaluated and resolved against the dealer's final hand with individual wagers being separately resolved.

Abstract: The player is randomly dealt an initial poker hand, optionally of five cards, from a composite deck formed from two or more subdecks of cards. The player decides which of the initial cards to discard, if any, retaining the remaining cards from the dealt hand. The player receives replacement cards to replace the discarded cards. The player's final poker hand consists of the player's retained cards and the dealt replacement cards. The dealer evaluates the poker hand so reconstituted against a prespecified payoff table, and the player loses the game wager or receives a reward, as indicated in that payoff table. The payoff table determines the reward for a final hand based on the combination of suit, value, and source subdeck of the cards comprising that final hand.
