In 13 Leaves, players can play one or more cards of the same value that align with the sequence on the table. The cards must be of a value equal to or lower than the lowest card in the sequence, or of a value equal to or higher than the highest card in the sequence.
The first player to play all the cards in their hand wins. At the end of the rules, you'll find the expert variant, which consists of playing multiple games in a row with a scoring at the end of each game.
