A video poker system and method allow a player to play a primary game in a conventional fashion while seeking a bonus payout based on cards from the primary game poker hand and one or more secondary poker hands from separate decks of cards. Certain pre-established poker hands (e.g., 4s of a kind) formed using cards from the primary game poker hand and the one or more secondary poker hands provide bonus payouts. A bonus hand may comprise a royal flush hand made using one royal flush card from each of five secondary poker hands. The system and method increase player interest, player wagers and provide meaningful bonus payouts.
