Modular

The purpose of the game is to clear the board! Try to do it as quickly as possible for different modulus values and beat your own score.

On clicking an empty tile once, the neighboring tiles are highlighted. If the modulus of sum of neighbors is equal to the incoming integer, then upon a second click, the neighboring tiles are cleared. Else, the integer is added at the tile.

The modulus value can be selected from the "Modulus Value" tab.

Good luck!
