In Hey, That's My Fish!, players want to catch as many fish as possible with their waddle of penguins. Each turn, a player moves one penguin in a straight line over hex-shaped ice tiles with 1, 2 or 3 fish on them.

The player then collects the hex from where the penguin started its movement from the table, thereby creating a gap which penguins can't cross on future turns. When a penguin can't move, it's removed from play with its owner claiming the tile on which it stands. The player who collects the most fish wins.
