About this game

Tap a screw, watch it spin out, drop it into a matching-colour collector. Free every board and the level is yours.

Knurl is the rare puzzle that stays calm while still making you think.

EASY TO LEARN, SATISFYING TO MASTER
- Screws pinned under a board can't be reached until you free what sits on top, so the order you choose is the whole puzzle.
- Collectors hold a limited number of screws and your holding tray is small. Fill it with the wrong colours and you are stuck.
- Rusted screws, tighter trays and extra colours raise the difficulty a step at a time, never all at once.

OVER 1000 LEVELS
37 hand-built levels open the game, then more than a thousand generated ones keep going. Every board is checked before you see it: an impossible level never reaches you.

MADE TO FEEL GOOD
- Pops, particles and confetti on every solve
- Gentle vibration you can switch off
- One-tap Undo and Restart, plus a Hint for when you are genuinely stuck
- Pick any level you have already unlocked and replay it

NO STRINGS
Plays completely offline. No sign-up, no account, no in-app purchases. Coins are earned by playing, and the game is free, supported by ads.

Good for two minutes in a queue or an hour on the sofa. How far can you unscrew?
