Knot Puzzle: Untangle Lines

Free · In-App Purchases · Designed for iPad. Not verified for macOS.

Untangler is a minimalist knot puzzle game where one rule changes everything: no lines may cross. Drag the glowing dots around the screen and rearrange the network until every tangled line becomes clean and straight. What looks like chaos at first becomes a moment of clarity once you find the perfect layout — that satisfying click when the last red line turns green. Simple to learn. Surprisingly hard to master. Impossible to put down.

Most puzzle games shout at you. Untangler whispers. There are no flashing rewards, no aggressive notifications, no stamina meters telling you to come back tomorrow. Just a quiet, beautiful problem waiting to be solved. Perfect for: - Coffee breaks and short pauses in your day - Winding down before bed - Long flights and offline travel - Anyone who loves logic puzzles, graph theory, or planar problems - Fans of classics like Untangle, Planarity, and minimalist puzzle apps THE CHALLENGE Each level presents a graph — a set of dots connected by lines, all tangled together. Your job is simple: rearrange the dots so that no two lines cross. As you progress, levels introduce more nodes and denser connections, forcing you to think several moves ahead. Some levels you'll solve in seconds. Others will sit in the back of your mind until that "aha!" moment hits. NO ADS THAT INTERRUPT YOUR FLOW A small banner ad appears at the bottom of the screen to keep the game free. Don't want to see it?
