A move acts on the whole board
The original game begins with two tiles. A valid move shifts the tiles, merges compatible neighbors and adds a new tile. Pressing a direction that changes nothing does not add a tile. Planning one pair alone can leave the rest of the board trapped.
A new tile cannot merge twice in one move
The source marks newly merged tiles so they do not merge again during that move. For example, a row of four 2 tiles moving left produces two 4 tiles, not an 8. The merged value is added to the score.
Winning does not have to end the board
Making a 2048 tile opens the winning state, with a Keep playing option in the original implementation. The game ends when no spaces or adjacent matching pairs remain. A full board can still have a legal move.

Board and best score use localStorage when available.

Before the next click.
Is there an undo button in the original?
The linked original does not provide undo. Forks may add one, so advice about a clone may not apply here.
Does a refresh keep my board?
The source restores saved gameState from localStorage when it is available. If storage is unavailable, its fallback lives only in memory.
Can I move the save to another browser?
The original does not provide a cloud account or a normal save-export control. Browser-local progress does not automatically move between profiles or hosts.
