Brainstring Original Puzzle

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.

Not suitable for children under three years old due to small parts, keep out of their reach.
