The object of 4-Line Deuces Wild is to obtain a five-card poker hand that contains a winning combination. It differs from original Deuces Wild, since it has four lines of cards. Each line uses a different deck of cards. Each line is treated as a separate hand for the determination of any wins.

The better your hand, the bigger the payout. You choose how many and which of your cards are to be replaced. You may replace your cards only once.
