Untangler: Untangle Knots

Untangler is a minimalist knot puzzle with one rule: no lines may cross. Drag the glowing dots and rearrange the network until every red line turns green. What looks like chaos at first falls into place once you find the layout — and the moment the last line turns green is pure satisfaction. Simple to learn. Surprisingly hard to master. WHAT'S INSIDE - Endless levels, generated for you and checked to be solvable, with up to 20 dots on Hard - Daily Knot: a new puzzle every day, the same for every player. Keep your streak alive and share your result - Picture puzzles: every 5th level and every Daily Knot hides a picture. Untangle it and watch the dots glide into shape — collect all 30 - Three difficulties: Easy, Medium and Hard. Medium earns double stars, Hard triple - Hardcore mode: limited moves, a running clock, no hints, and every line stays red, so you have to spot the crossings yourself. How many knots can you clear in a row? - World leaderboard on Game Center: climb the ranks with your total stars - Share your solve as a short video - Undo, hints, shuffle or a brand-new board when you are stuck (Hardcore leaves you on your own) - Star ratings: solve with few moves and quickly to earn 3 stars - Detailed stats, streaks and level records - Plays offline, in English and Turkish, on iPhone and iPad WHY UNTANGLER? No energy bars, no lives, no waiting. Just a quiet, beautiful puzzle — for a coffee break, a long flight or winding down before bed. Perfect for fans of logic puzzles, graph theory and classics like Planarity. THE CHALLENGE Each level is a graph: dots connected by lines, all tangled together. Move the dots so that no two lines cross. Boards gain dots as you climb, so you will need to think a few moves ahead.
