In this block-style game, you have to place elements in their correct groups to create winning matches, for example, Noble Gases. Three correct matches score points and generate more random elements.

There are three levels:

Elemental: All elements are colour-coded with the atomic number and atomic symbol clearly shown. Score 5 points per group match.

Periodyx: All elements are colour coded with a pictorial representation of the element shown. Score 10 points per group match.

Einsteinium; All elements are a grey colour with the atomic number and atomic symbol clearly shown.Score 30 points per group match.

A timer bar (the speed of which varies according to the level that you are playing) times each move you make. This timer resets after every successful move.

There are four "nukes" per scene that will refresh the grid without loss of points.

High scores are retained, and leaderboards are available.
