The Japanese Ladder mechanical puzzle is based on the "Japanese crystal Puzzle" originally designed in Japan around the 19th century. This beautiful and intriguing mechanical puzzle is one of the most challenging puzzles in our interlocking puzzles collection. This perfectly symmetrical multifaceted celestial structure is made out of 51 non-identical interlocking bar pieces. Each piece precisely cut so the pieces can interlock perfectly to make a solid structure.
Like in many construction interlocking puzzles, the key to unlocking the puzzle is in turning just one piece, there are precise steps that you have to follow to unlock the puzzle.
This high-level difficult puzzle is perfect for serious puzzlers with a lot of extra time on their hands. Perfect for building focus, patience, and spatial reasoning!
Once you’ve solved the puzzle it makes a beautiful art piece to display on a bookshelf or coffee table.
