Rummz Z is played with 106 tiles which correspond to two decks of cards, including two jokers. The regular suites - Clubs, Spades, Hearts and Diamonds - are replaced by four colors bearing numbers 1 through 13 consecutively. The numbers, 1, 11, 12, and 13 replace the Ace, Jack, Queen and King respectively. The primary object of each round is to be the first to play all of your tiles from your rack to the table. The secondary objective is to hold as few points as possible at the end of each round. The winner of the game is the player to first score minus 1000 points.
