How to play
The board is four squares by four squares. Each move pushes every tile as far as it can go in the direction you chose, and any two tiles carrying the same number that collide on the way become one tile with double the value. Every move that changes the board also drops one new tile into a random empty square — a 2 most of the time, a 4 now and then. When no move can change anything, the run is over.
Your score is the sum of every tile you have created by merging. A 4 built from two 2s adds four points; the 2048 tile itself adds 2048 the moment it appears. That is why score and top tile are not the same measure of a run, and why two players who both reach 1024 can be hundreds of points apart.
Controls
- Desktop: arrow keys or W A S D.
- Phone or tablet: swipe in any direction on the board.
- Undo: steps back exactly one move, so you can see what a collapse looked like.
Strategy that actually moves your ceiling
Pick one corner and never let your largest tile leave it. Most players choose the bottom left, which means they use left, down and right freely and treat up as an emergency key. The reason is mechanical: the instant your biggest tile drifts into the middle, it splits the board into regions that cannot merge with each other, and the free squares disappear from both sides at once.
With a corner locked, build the bottom row as a descending staircase — biggest tile in the corner, then the next biggest beside it, and so on. Players call this the snake pattern, because when the bottom row fills you continue the sequence backwards along the row above it. A tidy staircase means a single well-timed move can cascade through several merges at once.
Two habits cause most avoidable losses. The first is chasing a merge on the far side of the board and pulling your anchor tile out of its corner to get it. The second is filling the board with lots of small odd values — a 4 stranded between two 16s blocks that whole line until something matches it. When you are running out of room, prefer the move that clears the most small tiles, not the one that scores the most points right now.
Rough milestones from our own play testing, offered as estimates rather than records: a first 512 tile usually arrives within a handful of attempts, 1024 tends to show up once corner discipline becomes automatic, and 2048 is a realistic target after a few dozen runs.
Where the game came from
2048 was written by Gabriele Cirulli in 2014 as a weekend project and released as open source. It was openly a remix of an earlier browser game called 1024, which in turn borrowed the merging idea from the mobile game Threes!. The version you are playing here is our own implementation, built for this site — the rules are the same because the rules are the fun part, but none of the code or text is copied from any other release.
One deliberate difference: new tiles come from your browser's cryptographic random number generator through a rejection loop, so no square and no value is quietly favoured. It is more machinery than a tile game strictly needs, and it means a frustrating spawn really was chance.
Questions players ask
Is 2048 always winnable?
No. Tiles spawn in random empty squares, so a run can be lost to placement even when you play well. Corner discipline wins far more often than not, but nothing guarantees the 2048 tile in a single attempt.
What is the highest possible tile?
On a 4×4 board the theoretical ceiling is 131072, and reaching it needs an almost unbroken chain of ideal spawns. For a human playing by hand, 8192 is already an exceptional run.
Does undo count as cheating?
It is a single step and it exists to teach you which moves collapse a board. Want a clean run? Do not press it. Either way the score is stored only on your device.
