Ring Sort vs Untangler

Tap to free a ring from pipe! Match three same color rings until all the pipes are freed. An easy to pick up yet challenging game to test your brain.

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.

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.
