About Zip Tie Untangle
Drag nodes to untangle crossing wires in this satisfying brain puzzle. 30 levels across 5 tiers of increasing complexity.
Description provided by GameZipper.
How to play
- Look at the tangled graph of nodes (circles) and wires (lines)
- Drag any node by tapping or clicking and holding to reposition it
- Watch wires turn green as you eliminate crossings (red wires are still crossed)
- Win the level by removing all wire crossings

This game supports touch, keyboard, mouse input; the exact controls are explained inside the game.
Questions
- What is an untangle puzzle?
- An untangle puzzle is a planar graph embedding problem. Players drag vertices on a 2D plane to reposition them so that no edges (lines connecting vertices) cross each other.
- Is every level solvable?
- Yes! All 30 levels are procedurally generated using planar graphs, which guarantees that every puzzle has at least one solution (a non-crossing embedding). The initial scrambled positions create the challenge, but a solution always exists.
- How do stars work?
- You earn 3 stars for solving a level with very few moves, 2 stars for moderate moves, and 1 star for completing it at all. Fewer moves = more stars.
