Each player chooses a magical creature to be their game piece. Players explore an island, gathering clues until they find the Selkie skin and defeat the guardian creature. A spinner built into the board determines movement as well as battle outcomes. Players move to different parts of the board and make a hypothesis. This involves telling another player what you think is the creature guarding the Selkie's skin, and what part of the island. If that player is holding either card, they must reveal one, disproving the player's hypothesis. A player who thinks he or she knows the answers can make a guess and check the set aside cards. If they are incorrect, the player must go back to Start. When a player guesses correctly, they must spin the spinner for a battle. If they spin the right magic weapon, they win the game. If they don't, the other players get to move.
