Puzzler's Cage was designed by Junichi Yananose in 1999 without the aid of a computer. He describes it as "crazy hard". The puzzle has more interlock than should be possible, with half of the stick ends captive in notched perpendicular pieces. Even with instructions, assembly is a daunting task.

CD used three different woods to give clues for solving. The beautiful tones of Bubinga, Schedua and Black Palm ensure this will hold a prized place in your puzzle display. Preferably behind glass so someone does not inadvertently disassemble it.

Notches and dimensions are very precise, with just enough room to prevent binding during the solve. Given the number of pieces and negative space, solving can be a bit of a dexterity puzzle. We recommended you keep it flat on a table to maintain a plane of reference during the process.
