ICECOOL2 is both a standalone game and an expansion for ICECOOL. If played on its own, ICECOOL2 differs from the original game thanks to:

 Tasks on 1-point cards

Fish-moving power on 2-point cards

Optional tournament scoring

If you combine both ICECOOL sets, you get:

 Multiple new layouts

New game mode called "The Race"

Games playable for up to eight players

Chance to create your own new layouts
