In this game, a cruel professor wants to freeze children's hearts. The players counter this by collecting a rainbow's icicles. An arrow is spun and determines how far a player can move. The squares show symbols which represent actions, notably removing or adding a thermometer chip onto the professor's thermometer. When it is hot enough to melt ice, 16 icicle cards can be collected. When all of them have been collected, they are flipped over and the players can see their value (1-3). The player with the highest number wins.
