How to play

Slide the full grid. Equal neighboring units merge once per move.

Controls

Arrow keys, WASD, touch swipes, or the directional pad.

Rules & result

Reach 2048 to complete the protocol. The run ends when no moves remain.

Scoring tip

Keep the largest tile in one corner and avoid random direction changes.

How Fusion Grid works

The board is generated in the browser and validated against the protocol rules after each move. No network request is needed to create or solve a round. Restart creates a clean state without reloading the page, and optional records remain on this device.

Accessibility and devices

The game uses visible text feedback in addition to color. Controls are keyboard-focusable, touch targets are at least 44 pixels, and motion is reduced when your system requests it.
