Composed of eight pieces of brass and stainless steel, the components fit together to form a cube with gently rounded edges.

The Tycho Puzzle also features a hidden interior cavity that’s a perfect place to conceal a meaningful surprise. The solution to the puzzle might initially seem obvious, but upon closer inspection there are nuances, asymmetries, and interferences that prevent a simple stacked approach.
