Progressive solving hints
These are original Crafty Puzzles hints based on the published objective and mechanism. They do not reproduce the manufacturer's challenge booklet or solution diagrams.
Hint 1
Follow one colour at a time rather than watching every string at once.
Hint 2
Move endpoints in small steps and check the centre after each change.
Hint 3
If a crossing becomes difficult to reverse, undo the last few moves instead of adding more tension.
Background
Recent Toys lists Brainstring Original as one of its signature brainteasers and describes the goal as rearranging the strings without creating a knot.
