Use the arrow keys to move the active cell (starts at lower-right corner) and the enter/return key to drop it. When the active cell is dropped, any adjacent cells which contain a number which is a multiple of the dropped cell will disappear (providing that there are at least two such cells). The greater the number of cells which disappear at a time, the greater the point increment.

SCORING:

1. The number of disappearing cells squared is the point increment.
2. When 100 points is reached a new level is created.
3. Score is computed by dividing points by moves.
