Twistio
Untangle knots in 3D
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Lift a rope end, drop it on an empty peg, and clear every crossing. A new knot every day, the same for everyone.
Ropes lie across a wooden board, each end resting on a peg. Some cross over others.
Lift a loose end, drop it on an empty peg, and a crossing comes undone. When no rope crosses another, the card is solved.
How it plays
- Touch a loose rope end and drag it to an empty peg.
- A rope with another lying across it stays put. Move the one on top first.
- Turn the board with a finger to see which rope sits on top. It stays at the angle you leave it.
- Undo is free, as often as you like.
- Stuck? A hint shows one good move, and that card then tops out at two stars.
Four ways to play
- Today's knot: one card a day, the same for everyone. Tap Start, solve it, and see where your time ranks. Come back on consecutive days to build a streak.
- Rush 90: as many small knots as you can solve in 90 seconds. Your best run of the week is ranked.
- Journey: chapters that add one idea at a time, from two ropes up to six.
- Zen: endless knots. No clock, no score.
Stars and score
- Three stars go to a solve inside par without a hint.
- The clock counts up and never runs out. A quick solve adds a bonus.
- Replay any solved card from Progress to raise its stars. What you have earned never goes down.
Spools
- Solved cards, the daily chest and badges pay out spools.
- Spend them on hints, skips and streak freezes, or in the Workshop on rope palettes, board woods and peg finishes. Stars unlock those too.
- Packs of spools are on sale if you want more.
Good to know
- Journey, Zen and the Workshop play offline. Rankings need a connection.
- No account needed.
- Free to play.
- Two looks: Studio, a warm paper stage, and Midnight, a deep blue night.
