Untangler vs Fudeto

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. FREE TO PLAY A small banner keeps the game free, and an optional ad can skip a level or add 5 moves in Hardcore. A one-time "Remove Ads" purchase removes the ads forever and gives you one free skip a day and +5 free moves once per Hardcore run. No subscriptions. Requires iOS 17.6 or later.

In 1736, Swiss mathematician Leonhard Euler studied the Seven Bridges of Königsberg: could you cross every bridge exactly once? His answer — based on the parity of vertex degrees — founded the field of topology. 290 years later, Fudeto turns Euler's question into your daily puzzle. Every day at midnight UTC, a graph of 6 to 20 vertices appears on your screen. Trace every edge in one stroke — and players around the world face the very same graph. A mathematical guarantee: Euler's 1736 theorem ensures every puzzle has a solution. The graph is generated live from today's UTC date — different every day, identical worldwide. — What makes Fudeto different — · Zero images, zero music, zero fonts. Every dot, line and colour is computed live in pure code. · Live Pulse — a faint heartbeat along the bottom of the screen while you play. · Solve Stillness — a held moment of quiet when you solve, before the next prompt fades in. · Render Fingerprints — every graph is rendered subtly, uniquely. — Content that keeps going — 1.
