Many Las Vegas casinos have in recent years added a slot club that allows them to reward customers for frequent play. Members are issued a club card, similar in appearance to a credit card, that the player inserts in the machine before beginning play. The player accumulates points which can be redeemed for cash, merchandise, food, rooms, or whatever that particular casino has dreamed up.
In keeping with the times Deuces Wild also has a slot club, which it uses to keep track of each player's results and preferences for play.
