Cubes 2048.io takes the merging idea from 2048 and drops it into a live arena. You steer a cube with a number on it around a board scattered with other numbered cubes; run into one with your value and they merge into double, so a 2 becomes a 4, then an 8, then a chain of cubes trailing behind you like a snake.
The .io half is what makes it tense: other players are doing the same thing, and running into a larger player's chain ends your run while running into a smaller one absorbs it. It is a genuinely clever mashup and one of the more popular browser games of the last few years.
Run into a cube showing the same number as yours and the two combine into one of double the value — the same rule as 2048, played in real time.
Prioritise merges over collecting. Absorbing loose low cubes lengthens your chain but doesn't raise your value; only same-number merges double you up.
Yes — a light browser .io game with nothing to install. It needs a live connection.
