Fold

Everything returns to one.

FOLD is a quiet geometric meditation. Every tile on the board moves as one; equal values meet, merge, and double. Resolve the whole field into a single target tile — fewer moves, purer form.

• 150 endless studies — a deterministic generator with a conservation invariant, so every board is solvable.
• Daily puzzle — one shared form per day, same for everyone.
• Five languages — English, Español, Português, 中文, 日本語.
• Three-minute levels — no install, no ads, no noise.

A puzzle you can finish between two sips of coffee.
