Join the numbers and get both ±64 tiles!
New GameHow to play: Use your arrow keys to move the tiles. When two tiles with the same number touch, they merge into one. When two tiles with opposite signs touch, they cancel out, leaving a zero tile.
Note: This site is the official version of ±64. Source is available on GitHub at cuviper/pm64.
