Sacculus is played on several rounds in which players try to get gems worth 15 or more points using their cards. In each round, four stones are randomly drawn out of the pouch. Both players then pick one of their cards and place it hidden in front of them. They then try to guess which card their opponent played. If they do, the guessed card will not work. Players whose card were not guessed will do what's on their card and can get some points. At the end of the round, all cards are returned to the players and the game continues until a player reaches 15 or more points.
