🕹️ How to play

How to start 2048: Open the page and two tiles appear (usually 2, sometimes 4) — no download or sign-up. An unfinished game auto-resumes; tap New Game to start over.
How to slide and merge tiles: On phone, swipe the board in one direction; on desktop use the arrow keys. Every tile slides to the edge, and two adjacent equal tiles along the way merge into a doubled tile (2+2=4, 4+4=8), scoring the merged value.
What happens after each move: If any tile moved or merged, it counts as a valid move and a new tile spawns on a random empty cell (about 90% a 2, 10% a 4). If a direction changes nothing, no tile spawns and no move is counted — just try another direction.
How to undo and win or lose: Tap Undo to roll back the last board and score (undo never lowers your best). Make a 2048 tile to win and optionally keep going; when the board is full with no possible merges, the game ends and shows your final score, best tile and moves.

📖 Rules & variants

Basic rules: 2048 is played on a 4x4 grid of 16 cells. Each move pushes all tiles up, down, left or right; two adjacent equal tiles along the direction merge into one doubled tile, and the merged value is your score. The goal is to build the 2048 tile.

Merge constraint: each tile merges at most once per move. A row of [2,2,2] sliding left merges only the edge pair into [4,2]; [2,2,2,2] becomes [4,4], never chaining into an 8. To build big numbers, line equal tiles up before pushing.

Spawning: after every valid move a new tile appears on a random empty cell, about 90% a 2 and 10% a 4. Only real movement or a merge triggers a spawn; a direction that leaves the board unchanged is an invalid move that spawns nothing and is not counted.

Undo and resume: on top of the classic rules we add one-tap undo — the board and score before each valid move are remembered, so you can take one step back (undo never lowers your best). Progress is saved locally and auto-resumes on refresh, no login or network needed.

Winning and continuing: reaching a 2048 tile wins; you may keep going for 4096, 8192 and beyond, or stop and view your score. The game ends when the board is full and no move can merge anything. Score accumulates from merges, best only ever increases, and beating it triggers a celebration.

❓ FAQ

How do you play 2048?

Slide the 4x4 board in one direction to merge equal adjacent tiles into doubled tiles — 2+2=4, 4+4=8 — all the way to 2048 to win. After each valid move a new tile appears, so the goal is to keep merging into bigger numbers before the board fills up.

What are the best tips to score high in 2048?

Keep your largest tile pinned in one corner, mostly push just two adjacent directions, and avoid moves that drag the big tile away. Build a descending chain of big tiles along one edge and feed smaller tiles into it. Keeping one edge ordered greatly reduces gridlock.

What is the largest tile you can reach in 2048?

The theoretical maximum on a 4x4 board is about 131072, but that takes near-perfect play; reliably reaching 2048 or 4096 is already strong. Making 2048 completes the standard goal, after which you can keep going for a higher personal best.

What are the rules of 2048?

Each move slides all tiles to the edge; two adjacent equal tiles in that direction merge and double, scoring their sum, and each tile merges at most once per move. A valid move spawns a random 2 or 4, and the game ends when the board is full with no possible merge.

Where do the 2s and 4s come from in 2048?

They are new tiles the game spawns on a random empty cell after every valid move — roughly 90% a 2 and 10% a 4. A spawn only happens when a move actually shifts or merges tiles; if a direction changes nothing, no new number appears.

Can you undo a move in 2048?

Yes. This 2048 supports one-tap undo — tap Undo to roll back to the previous board and score, so a mis-swipe is recoverable, and you can even undo one step after the game ends to keep playing. Undo only affects the current game and never lowers your saved best.
