In Catena, players try to form the best chains possible. The game board consists of 16 pearls, which are lined up on 7 chains. There are two chains with 1 pearl, two chains with 2 pearls, two chains with 3 pearls, and one chain with 4 pearls. Each player tries to win as many chains as they can during the game. A chain scores as many points as there are pearls on it. For example, a chain with three pearls counts as three points. The player with the most points at the end of the game wins.
