US Patent 7306517 Wagering gaming and method of play

A game enhances conventional video poker by providing players an enhanced opportunity to hit four of a kind. Ideally, players are provided an option to place a wager once five initial cards are displayed. The option is provided in response to the five dealt cards including one or more pairs. Should the player elect to place the wager, the player must retain one pair and a kicker. The player is then provided with a fourth card having a rank the same as the rank of the pair. The player now holds three of a kind and a kicker. Finally, a fifth and final card is displayed. If the player obtains a four of a kind, the player receives a payout. Other versions include a progressive jackpot and the option to buy cards.
