Who is the best fisherman? One player takes the role of the two anglers and tries to catch as many fish as they can. The other player takes on the role of the fish and with bluff and skill tries to hinder the anglers from catching fish. The angler player decides where to fish, but must do so in the dark (that is, they cannot really see where the fish are), as the fish cards are placed face down. Because of this, they do not know whether they are catching a fish or garbage. Also, when they are lucky enough to catch a fish, they will not know until they land how valuable it is. With clever movement of their fish, the fish player tries to get garbage and small fish onto the anglers hooks.

After one game, the players swap roles. After two games, the player who has the most points is the winner.

Gone Fishing! is part of the Kosmos two-player series of games.
