Recent Toys Brain String Original World's Most Fascinating Brainteaser Ages 7+

The mystery of Brainstring Original isn’t just how to untie a twisted ‘knot’ of strings in the centre, but how it can be that all its strings can be interchanged— WITHOUT creating a knot! Four groups of different coloured strings, four strings per group, moving up, down and around all six sides of a polycarbonate shell… beyond just tying or untying a knot, what kind of beautiful symmetries can you create? Brainstring Original isn’t just a puzzle — it’s a work of art.

• Move the pegs along the tracks ro change the positions of the strings.
• Sort the pegs so each side has just one solid colour.
• Solve by untangling the knot and sorting the colours.
