How to play
Drag anywhere to turn the knot. Red beads mark where strands still cross, and a counter tells you how many are left. Find the clean angle and the knot settles flat on its own.
Swipe up whenever you want the next one.
Common questions
Do I need an account?
No account, no sign-in.
Can I play offline?
The puzzles play offline and each card is generated on your device.
How does difficulty change?
Every card is generated on your device, so there is always a next one. Difficulty rises by card number, one step at a time, the same for everyone. There is no clock.
Where are the settings?
Settings are behind the gear icon, top right. Studio is a warm paper stage. Midnight is a deep blue night. Switch any time in settings.
Does Twistio cost anything?
Twistio is free. The current version has no purchases or subscriptions.
How do I turn off notifications?
