Brainstring Original Puzzle

The mystery of Brainstring Original isn’t just how to untie a twisted ‘knot’ of strings in the center, but how it can be that all its strings can be interchanged—WITHOUT creating a knot! Four groups of different colored 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.

It’s knot what you think
