Brainstring Original - level 3

The mystery of the Brainstring Original lies not only in how to untie a tangled "knot" of strings in the center, but also in the fact that all of its strings can be interchanged—WITHOUT ever creating a knot! Four groups of different colored strings, four strings per group, moving up and down and around the six faces of a polycarbonate shell… Beyond simply tying or untying a knot, what beautiful symmetries can you create? Brainstring Original isn't just a puzzle—it's a work of art.
