SquareMath 2

A puzzle game of thinking and spatial logic.

The goal is to clear the board with zeroes in all buttons. To do so, choose a number to add or subtract with the "+" and "-" buttons. Then press on a button on the board. The number will be added or subtracted to the button and its neighbors.

As you finish levels you will unlock new ones, each time slightly harder.

Games are saved so you can finish playing later if you are interrupted.
