AgeOf2048

No download, no account: AgeOf2048 is a Puzzle game that runs where you found it. Taps and swipes are the whole vocabulary — a phone plays it best. Listed under 1 player, 2048, best games, puzzle.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Close the tab and come back later; the game is still one click away.
