Breaking Even

Think fast! 

The board is filled with unstable odd numbers and you must make them even before they explode!

Controls:

     Left click a tile to select it, and click an adjacent tile to transfer 1 to it from the selected tile.

Rules:

     Odd numbers can only transfer to tiles to the left and right.

     Even numbers can only transfer to tiles above and below.

     0's cannot transfer to any adjacent tile.

     9's can not be transferred to.

     Once all numbers are even, the board is complete!
