How to play 2048

The rules

A four-by-four grid. Each move slides every tile as far as it can go in the chosen direction. Two tiles with the same number that collide merge into one tile of double the value. After any move that changes the board, a new tile appears in a random empty cell — a 2 most of the time, a 4 occasionally.

You win by creating a 2048 tile. You lose when the grid is full and no two adjacent tiles match, so no move changes anything.

The detail that matters: one merge per tile per move

If a row contains 2, 2, 2, 2 and you slide left, you get 4, 4 — not 8. Each tile can only participate in one merge per move. The pairs form from the direction you are sliding toward, so the leftmost pair merges first.

This rule is why you cannot simply spam one direction and expect everything to collapse. It also means the order you press matters as much as which keys you press.

Scoring

Every merge adds the value of the resulting tile to your score. Merging two 64s into a 128 adds 128 points. The score is therefore determined entirely by which merges you make, not by how long you survive.

Reaching 2048 for the first time typically scores around 20,000. Reaching 4096 roughly doubles that.

Why most people lose

The failure mode is almost always the same. Big tiles end up scattered across the board — a 256 in one corner, a 128 in the middle, a 512 somewhere else. They cannot reach each other, they cannot merge with anything, and they occupy space permanently until the grid fills up.

Everything in 2048 strategy is about preventing that.

The one rule that changes everything

Pick a corner and never let your largest tile leave it. In practice this means choosing two directions you use freely and one you almost never press.

If your corner is bottom-left, slide down and left constantly, right occasionally, and up essentially never. Pressing up lifts the bottom row, and if the largest tile moves off the corner the structure collapses.

Building a row

With the corner fixed, aim to keep the whole bottom row in descending order — largest in the corner, then smaller going along. That way each tile has a neighbour it can eventually merge with, and the row collapses in sequence rather than getting stuck.

Controls

• Arrow keys, or W A S D.
• Swipe in any direction on a touchscreen.
• The on-screen pad, which appears on smaller displays.
• Undo takes back one move — useful when you press the wrong direction.

Your first serious attempt

1. Choose bottom-left as your corner.
2. Alternate down and left. Use right only when neither changes the board.
3. Never press up.
4. Keep the bottom row in descending order from the corner.
5. When the bottom row is full and matched, one left press collapses it into something large.
