Which project does this player open?
This is the classic open-source 2048 by Gabriele Cirulli, hosted here under its MIT licence. It has the original four-by-four board. Versions advertised with undo, power-ups or larger grids describe different rules.
Launch and keep the complete view
Arrow keys or swipes move the whole board. Equal adjacent tiles can merge, and empty spaces matter as much as the next score. The game keeps its own board and best score when browser storage is available. RadiantGames favourites retain only the page address.
