2048 Cube Buster

Browser Hypercasual: 2048 Cube Buster needs a tab and nothing else. Taps and swipes are the whole vocabulary — a phone plays it best. Listed under 3d, 3d games, block, board, bricks.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Everything runs client-side, so there is nothing to set up before you start.
