What Is 2048?
2048 is a sliding tile puzzle played on a square grid, usually 4×4. Each turn you move every tile in one direction at once — up, down, left or right — with the arrow keys or a swipe. When two tiles showing the same number collide they merge into a single tile of double the value, and the aim is to build a tile worth 2048.
Two 4-tiles become an 8, two 256-tiles become a 512, and so on up the chain. A freshly merged tile cannot merge again on the same move, so a row of four 4s becomes two 8s rather than a single 16.
The goal and how the game ends
A new tile spawns in a random empty cell after every move — a 2 about nine times out of ten, a 4 the rest of the time. The nominal goal is to create a tile with the value 2048, but the game continues beyond that for players chasing higher scores and larger tiles like 4096, 8192, or beyond.
The game ends when every cell is occupied and no two adjacent tiles share the same value — at that point no merges are possible and no new tile can appear. Does 2048 have an ending? covers that condition in detail.
The complete rules
There are only seven of them, and they have not changed since 2014:
| Element | Rule |
|---|---|
| Board | A square grid, 4×4 by default (16 cells) |
| Controls | Arrow keys or a swipe; every tile moves at once |
| Sliding | Tiles travel as far as they can in that direction, not one cell |
| New tiles | One per move, in a random empty cell — a 2 about 90% of the time, a 4 about 10% |
| Merging | Two equal tiles combine into their sum; a tile that just merged cannot merge again on the same move |
| Score | Each merge adds the value of the tile it creates |
| Winning and losing | You win when any tile reaches 2048; you lose when the board is full with no equal neighbours |
Where 2048 came from
It was written in March 2014 by Gabriele Cirulli, then a 19-year-old Italian developer, and released free and open-source.
On 2048.now, the original game mechanics are kept identical and extended with competitive ranked play across three grid sizes (4×4 Classic, 5×5 Large, 6×6 Expert), global leaderboards, seasonal rankings, and a cosmetic progression system.
