How to play: Use your arrow keys to move the tiles. When 3 identical numbers touch in a line, they merge into one. Work your way up to reach 729.

You can also play the game with Easter styling or Christmas styling.

Note: This game is a derivative of http://git.io/2048, created by Gabriele Cirulli. I've merely tweaked the code to require three rather than two tiles to touch, and modified the style.
