How to Play 2048 — Rules
2048 is a puzzle played on a 4x4 grid where you merge matching number tiles. The rule fits one sentence: slide all tiles in one direction; matching numbers merge once each. The merged tile's value becomes your score — make 4, score 4; make 512, score 512. Two tiles start on the board, and after each real move one new tile (90% chance of 2, 10% chance of 4) appears in a random empty cell. The game ends when no empty cells and no adjacent matches remain.
A commonly missed detail: each tile merges only once per move. Sliding 2 2 2 2 left produces 4 4, not 8. This prevents lucky mass-merges and creates the strategy of sequencing merges.
Three Principles for Higher Scores
First, pin your largest tile to a corner. Any corner works, but stick with it all game. A large tile drifting to the center forces every other tile to orbit it, draining empty cells. A corner-locked tile has two walls protecting it.
Second, seal one direction. If your big tile is top-left, avoid pressing down — that pulls the big tile off its corner. Three directions are enough. The basic rhythm is down-left-down-left, mixing in right only when neither down nor left moves anything. Before pressing right, confirm the bottom row is full so the corner stays put.
Third, line up large tiles in a snake pattern. Fill the top row left-to-right by descending value, the next row right-to-left, and so on in a zigzag. This keeps big tiles adjacent, so smaller tiles from below are absorbed in chain merges. The 1024-to-2048 leap almost always happens on this pattern.
When You Are Stuck
Board locks almost always trace to two causes: the big tile left its corner, or matching pairs are stranded on different rows. Prevent the first by honoring the sealed direction; prevent the second by habitually counting how many mergeable pairs remain. Below two pairs is a danger signal — prioritize creating pairs over scoring. If it is too late, use undo. Undo here is unlimited and ad-free.
Speed causes mistakes too. Button-mashing slips in an unintended direction that breaks the corner. Inputs are throttled at 80ms, but looking at the board before each press is far better for your score.
Daily, 5x5, and Replay GIF
Daily mode Daily mode gives everyone the same tile sequence for the day — luck removed, pure judgment. Rankings are daily-only. Retry as many times as you like; only your best score counts. The 5x5 variant has more room, making it forgiving for beginners aiming for their first big tile. The goal is 4096 and records are tracked separately.
After a game ends, you can turn the last 30 moves into a GIF. The animation captures the satisfying moment tiles click into place — great for sharing. Encoding happens entirely in the browser with nothing sent to any server. For deeper strategy, see the strategy guide. strategy guide
2048 Explained · One swipe moves the whole board
Rules: every tile slides the same way
Each move slides every tile on the board as far as it can in the chosen direction. When two tiles with the same value collide, they merge into one and the new value is added to your score. A tile that has already merged during a move cannot merge again in that same move, so pushing a row of 2·2·2·2 gives two 4s, not one 8.
A new tile appears in an empty cell only when something actually moved. Nine times out of ten it is a 2, otherwise a 4. The game ends when no direction changes the board, and building your first 2048 tile counts as the win.
The standard board is 4×4. You can also pick a roomier 5×5 variant; nine extra cells make each mistake far less costly, which makes it a good place to chase tiles beyond 2048.
Controls: arrow keys, WASD or swipe
- Desktop: arrow keys or W, A, S, D. WASD keeps working even when a Korean input method is active.
- Phone or tablet: swipe across the board in the direction you want.
- Undo: press U or tap the undo button. There is no limit.
- Daily mode deals the same tile sequence to everyone on a given date, so scores from that day can be compared fairly.
Strategy: use three directions, not four
Most high scorers almost never press one direction. If you keep your biggest tile in the bottom-left, alternate down, left and right, and press up only when nothing else is legal. Pushing up lifts the corner tile and lets a stray 2 slip underneath it, which is how most boards collapse.
Line up the row next to the corner tile in descending order, such as 1024, 512, 256, 128. When the row forms a staircase like this, building one more 128 at the end triggers a chain of merges all the way to the corner. Players often call this the snake or the ladder.
Before merging whatever can merge, count how many empty cells the move will leave. A move that drops you to two or three free cells is usually worth skipping even if it scores more.
History: a weekend project that hooked the world
2048 was built over a weekend in March 2014 by Gabriele Cirulli, a 19-year-old developer in Italy, and released as open source. He started from a similar web game called 1024, which in turn traced back to the mobile puzzle Threes!, launched the month before.
Within a week millions of people had played it, and because the source was public, thousands of variants followed, from hexagonal boards to a periodic-table edition. The fact that a ruleset the Threes! team had refined for over a year spread for free within days is still cited in debates about cloning and credit in game design.
On a 4×4 board the largest tile that can theoretically be built is 131072. That figure assumes a perfect staircase of powers of two filling all sixteen cells, so in practice only search-based AI players get anywhere near it.
Questions about 2048 scoring and play
- Roughly how many points is one 2048 tile worth?
- Each merge adds the value of the new tile, so building a single 2048 tile entirely from 2s earns 20,480 points along the way. When 4s appear, some merge steps are skipped and the real total is a little lower. A score around twenty thousand is a good sign that you are close to 2048.
- Does the big tile have to live in the bottom-left corner?
- Any corner works. What matters is sticking with the corner you chose until the game ends. If swiping right feels more natural, anchor on the bottom-right and save the one direction that would pull the tile out of that corner.
- How should strategy change on the 5×5 board?
- Anchoring a corner and building a staircase still work. The difference is that each row has five cells, so a staircase can run five steps along one row, and the spare room means you rarely need to merge in a hurry. The wider board also lets 2s and 4s scatter, so make a habit of gathering small tiles in one area on the far side from your staircase.
