How to play the Googol Game?
Use arrow keys to slide tiles. Tiles move and merge when two of the same number collide while moving.
Increase your score when tiles combine, adding the value of the new tile.
The game ends when no legal moves are left, marked by no empty spaces and no adjacent tiles with the same value.
