Turns are simple: Flip over an ocean tile, and see what you reveal. You can take what you reveal in the shallows or dive deeper, hoping for a larger catch — but the deeper you go, the more plentiful the predators become. As you surface with food, you build sets of three colors. Target the colors you need to complete sets and score the maximum number of points.

When one of the depths of the ocean has been fully explored, the game ends and the penguin waddle with the best sets of food wins!
