Untangle
Drag the knots on a sheet of notebook paper until no strings cross. Endless levels grow bigger and add nailed-down knots, with timed three-star goals and hints.
Untangle is a calm planarity puzzle drawn in ink on warm notebook paper. Each level is a web of knots joined by strings, and every string that crosses another glows red. Drag the knots around until every line turns green and nothing overlaps. Every crossing you remove plays a rising chime and pops a little counter, so you can feel the knot loosening as you work, and the whole web flashes green when it comes free.
Every puzzle is generated from a hidden layout that is guaranteed to have a crossing-free solution. Early levels have only a handful of knots in small local tangles, then each new level adds more knots, more strings and wider scrambles. From level 5 some grey knots are nailed in place at their true positions, so you must arrange everything else around them. A timer tracks each solve: beat the par time for three stars, or twice the par for two. A hint circles the knot causing the most trouble but adds ten seconds. Stars unlock levels and raise your rank from Loose Thread to Master Untangler.
This line-untangling logic game suits anyone who enjoys spatial puzzles at their own pace. Tip: pull the outer ring of knots into a rough loop first, then tuck the inner knots into the gaps.
How to play
Drag the knots (circles) so that no two strings cross. Crossing strings are red; the level is solved when every string is green. Grey nailed knots cannot move. Solve under the par time for three stars, or under twice the par for two. A hint highlights the knot with the most crossings but adds 10 seconds. Your score is your total stars across all levels.
