Merge 2048 Cake

Merge 2048 Cake is listed here under Puzzle. There is no launcher and no install between you and it. Designed around touch input, and comfortable on a small screen. Catalogued as 1 player, 2048, 2d, android, board.

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.
