2048

2048 is based around a simple concept: using the arrow keys, you slide pieces around a 4×4 grid. Every movement sends the tiles as far as they will go in a given direction, and then a 2 – or sometimes a 4 – will randomly spawn on the board. Sliding two of the same number into each other gives you the next power of two: so, two 4s combine into an 8, and two 16s give you 32. 2048, can therefore only be achieved through forcing identical 1024 squares to bump in the same place, at the same time. The tiles change colour as their value increases.
