You are an aquarium keeper searching for the one penguin that no one has seen.
Players take turns acting as the lead player, and the game unfolds with trick-taking–style play, where following the suit—here, the penguin species—matters.

Each penguin belongs to one of three species, and players must play a penguin of the same species as the one led by the active player. But what happens if you don’t have a penguin of the required species…?
By choosing and playing cards carefully, you gather clues about the other players’ hands and deduce the whereabouts of the missing penguin.

Through this clever blend of deduction and trick-taking mechanisms, the game offers a rich, puzzle-like experience packed into a short playtime.
Enjoy a tense and satisfying logical challenge that unfolds with every card played.
