Join the elements and get to the tile with 256 isotopic mass! Watch out for unstable elements though, as these won't be around forever!
How to play: Use your arrow keys to move the tiles. When two tiles with the same number touch, they merge into one!
Update (8th April): I've created an official Facebook page for this game, which can be found here. I'd love to hear any suggestions you may have!
Note: This site is a fork of the official version of 2048, which can be found here.
