Classic puzzle game in which it is necessary to place boxes in the designated places and freeze the molecules with each ice box. In this version, there is the added element of coloured boxes, making the puzzles more unconventional and logically complicated. Boxes of a certain color can only be moved after drinking a vial of the same color. The grey box is neutral and can be moved at any time.

There are 100 levels in the game, each of which is named after a prominent figure of humanity and usually has its own unique character.

The game is controlled with the cursor arrow keys and the help keys.
