Loose Lines Untangle Game
A calm untangle game: drag the dots until none of the lines cross.
How to play
Loose Lines is an untangle game with one rule. You get a set of dots joined by straight lines, and you drag the dots around until no two lines cross each other. Every puzzle is generated so that a crossing-free layout exists. It does not have to look tidy, it only has to be untangled.
Under Type you can pick how many dots the puzzle has: 6, 10, 15, 20 or 25, or set your own number with Custom. Small puzzles take a minute. The bigger ones become a slow, satisfying job of sorting out one corner at a time.
There is no timer and no move limit. Undo and Redo step through your moves, Restart puts the dots back where they started, and New gives you a fresh puzzle of the same size.

Tips
- 1Find a dot with only two or three lines and park it near the edge first.
- 2Look for small loops of three or four dots and give each loop its own patch of space.
- 3Move dots out of the crowded middle before you try to fix individual crossings.
- 4If one area gets worse every time you touch it, leave it and work on another corner.
