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
