Platforms: Browser, Mobile

Instructions

Use the arrow keys to slide every tile on the board in that direction at once; two tiles with the same number merge into one tile with double the value the instant they collide, and after every move the game drops a new tile into a random empty cell — 90% of the time a 2, 10% of the time a 4.

The game is won the moment any tile reaches the value 2048, but the board keeps accepting moves afterward if you want to keep merging toward higher tiles once that condition is met.

Press the Auto-run button to hand control to the built-in solver, which picks each move by evaluating board smoothness and monotonicity rather than playing randomly — watching a few of its moves is a fast way to see why keeping your highest tile in a corner matters.

Controls

Arrow keys / H,J,K,L — slide the grid; vim-style keys work as an alternate scheme
Swipe — swipe on touch screens to merge tiles
Space — restart with a fresh board

Tips to Master 2048

Because every arrow-key move slides the entire board in one direction, a high-value tile that is not pinned in a corner gets shuffled around and blocks merges instead of anchoring them. Picking one corner and repeatedly sliding toward it keeps your largest tiles stacked in descending order along that edge.

Watch the 90/10 spawn odds

New tiles spawn as a 2 nine times out of ten and a 4 the rest of the time, always in an empty cell. Since you cannot control where the new tile lands, leaving at least one empty row or column gives the spawn room to land without immediately blocking your next planned merge.

Avoid sliding toward your empty side

The board only fills up once open cells run out, so repeatedly sliding in the direction that empties tiles away from your corner strategy is what causes most losses — once movesAvailable() returns false because every adjacent tile has a different value, the run ends immediately.
