About the game
2048 is a sliding puzzle played on a 4x4 board where you merge tiles that carry the same number. Two 2s become a 4, two 4s become an 8, and so on, doubling your way up until you finally build the 2048 tile. The rules take seconds to learn, yet every single move reshapes the whole board, which is why the game keeps revealing more depth the longer you play.
This version runs directly in your browser with no installation or sign-up. On desktop you play with the arrow keys; on mobile you simply swipe across the board. Your score and best record are saved automatically on your device, so you can come back any time and chase your own high score. A single run can last a few minutes or the better part of an hour, and each one delivers a quiet sense of accomplishment.
How to play
- Desktop: press the arrow keys to slide all tiles in that direction.
- Mobile: swipe up, down, left or right anywhere on the board.
- Use the Pause button to take a break and Restart to begin a fresh board.
Rules
- One input slides every tile as far as it can go in that direction.
- When two tiles with the same number collide they merge into one, and the merged value is added to your score.
- A tile that has already merged cannot merge again during the same move.
- After every move a new tile (2 or 4) appears on a random empty cell.
- The game ends when the board is full and no adjacent tiles can merge.
- Building a 2048 tile counts as a win, and you can keep playing for even bigger tiles.
Strategy & tips
Anchor your biggest tile in a corner
The core strategy of 2048 is to park your highest tile in one of the four corners and defend that spot. If the big tile drifts into the middle of the board, merge paths tangle up and the board clogs surprisingly fast.
Restrict yourself to three directions
If your anchor corner is bottom-left, for example, treat the Up key as forbidden. Limiting yourself to three directions dramatically reduces the accidents that knock your big tile out of its corner.
Keep one edge sorted like a staircase
Arrange the edge row that contains your anchor corner in descending order, largest to smallest. New tiles then feed naturally into chain merges. Players often call this the snake formation.
Slow down when the board gets tight
With only three or four empty cells left, one careless move can end the run. Before each move, imagine where the worst possible spawn could land, and save your risky direction for when you truly have no choice.
FAQ
Does the game end when I reach 2048?
No. You get a victory message at 2048, but if you press Continue you can keep playing on the same board and chase 4096, 8192 and beyond.
Where is my best score stored?
Scores and best records are stored only in your browser's localStorage. Nothing is sent to a server unless you choose to submit a score to the leaderboard, and clearing browser data will also erase the records.
Do new tiles spawn as 2 or 4?
After every move a new tile appears on a random empty cell: a 2 with 90% probability and a 4 with 10% probability.
How is the score calculated?
Every merge adds the value of the resulting tile to your score. Merging two 64s into a 128, for instance, earns you 128 points.
