Untangle

Drag tangled lines apart until every connection lies flat—sounds simple, but your brain will twist into knots.

Untangle drops a mess of connected dots on your screen and dares you to drag them until every line runs clean. No two edges may cross. Sounds trivial, right? Then you load a level with fifteen points and realize the knot you're staring at looks like a plate of spaghetti after a toddler attack. I've spent more time than I'd like to admit nudging a single vertex millimeter by millimeter, watching a tangle of three crossings suddenly flatten out. What makes it work is the lack of punishment. There's no timer, no move counter, no score. You just grab a point, slide it anywhere, and the edges stretch like rubber bands. You can pull the outer ring into a rough circle to get your bearings, then work inward. Some levels seem impossible until you notice that two clusters can simply be swapped. That 'aha' when five intersections vanish at once? That's the whole hook. Because puzzles generate randomly, no two sessions feel the same. It's perfect for a mental reset between classes or while waiting for something to load. And yes, it runs on phones—touch dragging is natural. Just be careful: once you start untangling, it's weirdly hard to stop.

The goal is to arrange the points so that no line intersects.

Pull the outermost dots into a rough circle first—it gives you a frame to work inside. Don't panic when many lines cross; focus on clearing one intersection at a time. If a cluster looks hopeless, try dragging it to the opposite side of the board. Use small nudges instead of big jumps to avoid creating new crossings. Every level is solvable, so if you're stuck, take a breath and rotate the whole arrangement mentally.
