The greatest temptation when playing Captain Sonar doesn’t come during the game itself. It comes when you’re trying to find another seven people to play. You’ll want to call this a party game version of Battleship—and that’s an apt description. Like the best party games, Captain Sonar features a wonderful mix of yelling, cooperation, deception, role-playing, deduction, and speed. And, like Battleship, you put your naval vessel on a grid and hope the other team doesn’t luck into finding it.
