Twenty-two cards from a standard pack are distributed on the board; the aim is for the player to remove a determined number of cards, which will vary depending on the degree of difficulty.

To remove cards from the board, the rule is to obtain a sum of values equal to eleven. The value of all picture cards is ten; the remaining cards keep their face value. To remove a card, it must be placed face up, i.e. it cannot have another card on top.
