D!C!ASSETTE, a stylized display of the Italian for 17 (diciassette), is a bluffing card game in which players try to time when a set of cards on the table sum to 17 or more.

The deck consists of cards numbered 1 to 5 and cards with special effects, such as reversing the direction of play. Some of the numbered cards show their number on both the front and back of the card.

Each player has a hand of three cards. On their turn, they choose to play a card face up or face down to a row on the table, then draw a replacement card. Other players can then state “Diciassette!” if they think the cards in the row sum to 17 or more. If they are correct, they earn a daisy chip and the last person to place a card in the row takes a ghost chip; if not, the ghost chip and daisy chip are handed out the other way.

Players lose one daisy chip for every two ghost chips they obtain, and the first person to collect three daisy chips wins.
