Cubes 2048.io mashes the number-merging of 2048 with a snake-style .io arena. Steer your cube around the board, swallow the loose blocks scattered across it, and every time you pick up a cube with the same number the two merge into the next one up: 2, 4, 8, 16, and beyond. Your train grows with every merge. Ram another player from the side or behind and their whole line of cubes becomes yours, but get caught by someone carrying a bigger number and you start again from scratch. The higher you climb, the longer your tail and the bigger the target on your back. Collect kills, unlock new skins, and see how far past 2048 you can push before somebody takes you out.
