In Ligretto, each player has his own deck of forty cards, with cards 1-10 in four colors and a unique symbol on the back to identify which cards are his. At the start of each round, each player lays out 3-5 cards (depending on the number of players) face up in front of him to create his row; places a face-up stack of ten cards, seeing only the top card, next to his row to create his Ligretto stack; and holds the remaining cards in hand face down.
Playing at the same time, each player tries to empty his Ligretto stack. If he has a 1 on the top of any face-up stack, he plays it to the center of the table. If he has a 2 of the same color as any 1 in the center of the table, he can place the 2 on the 1. All cards in the central piles must be played in ascending order and must be the same color.
