The mystery of Brainstring Original is not only how to untangle a twisted knot of strings in the middle, but also how it's possible that all the strings can be interchanged without forming a knot! Four groups of differently colored strings, four strings per group, which move up, down, and around all six sides of a polycarbonate shell. Brainstring Original is not just a puzzle, it's a work of art.
