This puzzle game required you to move your cursor over the 'atoms' of a molecule that were contained in a maze. You could start an atom moving in a certain direction, and it would keep travelling until it hit an obstacle, be that another atom or a piece of the maze. The idea was to complete the molecule displayed at the bottom left of the screen within the time limit.
Devilishly simple yout fiendishly addictive, this was a perfect example of unputdownable puzzle fun.
