My record

Every tile slides as far as it can in the direction you choose. When two equal numbers collide they merge into one tile with double the value.
A tile can merge only once per move. For example, sliding 2 2 2 2 to the left gives 4 4.
After each move a new 2 (sometimes a 4) appears in an empty cell.
Your score goes up by the value of every merged tile.
Make the target tile to clear the game. The target is 2048 on 4x4 and 5x5, and 512 on the 3x3 challenge. After clearing you can keep going for bigger tiles.
The game ends when there are no empty cells and no tiles to merge. Ending before the target counts as failed.
Undo can be used up to 3 times per game, even after the game ends if you still have some left.
Your game in progress is saved in this browser, so you can close the window and continue later.

Keep your biggest number in one corner and keep that row full.
Try to use only two or three directions, and avoid moves that pull the big tile out of its corner.
