Use arrow keys to swipe cards in arrow direction. Same numbers merge when they collide.
About Number Merge
Free 2048 in your browser — the addictive number-merge puzzle. Swipe or arrow-key the tiles in any direction; matching numbers merge into their double. Combine your way up: 2 + 2 = 4, 4 + 4 = 8, all the way to 2048 (and beyond, if you don't get stuck first).
Pondernook number-merge tracks your local best score automatically. No signup, no install, no ads. Plays on phone (swipe) or desktop (arrow keys). The game looks simple but rewards careful corner-anchoring strategy: keep your biggest tile in one corner and build a snake from there. Sessions usually run ten to thirty minutes if you're going for a high score, or a couple of minutes for a quick distracted attempt.
Frequently asked questions
How do I reach 2048?
Slide every tile in one direction so equal numbers collide and merge — 2 + 2 = 4, 4 + 4 = 8, and onward. Keep merging and you can pass 2048.
Any strategy tips?
Anchor your largest tile in one corner and build a descending “snake” from it; avoid scattering big tiles across the board where they can't merge.
Is my score saved?
Your best score is stored locally on the device, so it's there next time — but it isn't tied to an account or synced between devices.
