The number of players determines whether the game can be played with one deck of cards or with two or more. Ten or thirteen cards are dealt to each playroyal casino slotser, with the remaining cards making up the draw pile. Making valid sets (three or four cards of the same rank) and sequences (three or more consecutive cards of the same suit) is the goal. The players alternately draw a card from the discard pile or the draw pile, then discard one card from their hand.
