2048 is a free online number puzzle you can play right in your browser — no sign-up, no download. Swipe to slide every tile on the board; when two matching numbers collide, they merge into one bigger tile. Keep combining — 2, 4, 8, 16, and beyond — and chase the legendary 2048 tile before the board fills up.

1. Swipe up, down, left, or right (or use arrow keys) — every tile slides as far as it can.
2. Two tiles with the same number merge into one when they collide.
3. Each swipe spawns a new tile, so space runs out fast.
4. The game ends when the board is full and no merges are left.
5. Build to the 2048 tile — then keep going for a new best.

💡 Tip: Pick a corner and keep your biggest tile parked there — swiping in only three directions keeps your board ordered and your merges chaining.
