Sonar*

Players engage in an underwater cat-and-mouse game where two sonar teams compete to deal two damage points to the opposing team to win instantly. Each team has the same pairs of cards in their color, with roles divided between captain and radio operator if there are two players, or one player assuming both roles alone. Players must strategically manage their energy reserves to maximize movement and actions like sonar use, firing torpedoes, or surfacing while avoiding enemy attacks.
