Players take turns playing cards from their hand to a central pool. The player earns points by playing a card, whose value matches the value of either one or more cards already in the pool, or the sum of several cards already in the pool. In either case, the player wins all the cards in the set and places them in their score pile.
The round ends when the draw pile has been emptied: Points are awarded for the yellow 7, for the most yellow cards, and for the most total cards. In addition, you can win a point for clearing the table.
The game ends after a set number of round.
