Be the first player to empty your Goal Pile by playing all 9 cards onto the center Build Piles. Cards go from Ace (1) through King (13).
The 4 center piles are shared. Start each pile with an Ace, then stack cards in ascending order (A, 2, 3... up to K). When a pile reaches King, it clears automatically.
Kings (K) are wild cards. They can substitute for any rank when playing to a Build Pile, making them extremely valuable.
Click on a card in your hand or Goal Pile to select it, then click a Build Pile to play. End your turn by discarding a hand card to one of your Discard Piles.
