Untangle Knots Puzzle

A tangle of lines and one rule: no line may cross another. Drag the dots around until every crossing is gone.

Levels open at four dots and grow from there. All 1,000 of them were run through a solver before they shipped, so a level you cannot finish is not in here.

There is no timer and there are no lives. Put it down halfway through a board and it will be waiting exactly as you left it.

• 1,000 levels, each one checked solvable
