Start the game
Shuffle the deck, deal nine cards to each player, place one card face-up in the center to start the discard pile. Set the remaining cards face-down as the draw pile.

Form sets
Organize your cards into three sets where the sum of two cards equals the value of the third card in each set (e.g., +2 and -7 add up to -5).

Drawing and Discarding
On your turn, draw one card from the top of the discard pile or the draw pile. If it fits any of your sets, replace one card from your hand with it. Place the discarded card face-up in the discard pile.

Continuing Play
The next player may draw the new face-up card or a face-down card from the pool.

Completing the Game:
The first player to successfully form their three sets shouts "Z!" and shows their sets for validation; the game ends, and scores are calculated by adding up the absolute values of the numbers in the incomplete sets of other players (e.g., -5, -4, and +2 would score 11).
Winning the game
Winning the Game: In tournaments, play three consecutive games; the player with the lowest total score wins.
