2048 Game - Free Online 2048 Puzzle

How to use this tool

1. Focus the board and use arrow keys or WASD to slide all tiles in one direction.
2. When two tiles with the same number collide, they merge into one worth double.
3. Undo restores your previous move; reach 2048 to win, then keep going to beat your high score!

How to play

The board is a 4×4 grid. At the start, two tiles (each showing 2 or 4) appear in random empty cells. Focus the board and use the arrow keys or WASD (or swipe on mobile) to slide all tiles in one direction. Every tile slides as far as possible until it hits a wall or another tile. When two tiles with the same number collide, they merge into a single tile with their combined value. After each move, a new tile (2 or 4) spawns in a random empty cell. The goal is to create a tile showing 2048.

Controls

Undo keeps only one previous move in memory while the game is open. It is disabled until a move changes the board, and using it consumes that history. Your personal best is recorded separately and is not reduced when you undo. Starting a new game or resuming an autosaved game clears the previous move history.

Scoring

Every time two tiles merge, you score points equal to the new tile’s value. Merging two 32 tiles scores 64 points; merging two 512 tiles scores 1024 points. There is no time limit, so your score purely reflects the quality of your merges.

Strategy tips

• Build your largest tile in a corner: pick one corner (e.g., bottom-left) and always keep your highest tile there. Avoid moves that pull it away from the corner.
• Chain along a wall: arrange tiles in descending order along one edge (1024 -> 512 -> 256 -> 128) so they merge in sequence without needing to travel far.
• Don’t fill the board: maintain free cells. When the board is nearly full, merges become impossible and the game ends quickly.
• Think two moves ahead: consider not just your current merge but how the board looks after the new tile spawns.

Tile progression & merge scores

Every merge combines two equal tiles into one tile with double the value. The score added per merge equals the resulting tile's value:

The chain shows exponential growth - each level doubles the tile value and the score earned. Reaching 2048 requires a minimum of 10 successful merge chains from the very first 2-tiles.

Maximum possible score

In a theoretically perfect game where every tile starts as a 2 and every merge is optimal, the maximum achievable score is approximately 3,932,156 points. This assumes the board is cleared in an ideal sequence with no wasted moves - a fun benchmark for competitive players pushing for high scores.
