Why is the Calibron 12 Puzzle Considered So Extremely Difficult?

The extreme difficulty of the Calibron 12 arises from several factors that AI and human problem-solvers will appreciate:

• Non-Intuitive Solution: The arrangement of pieces defies common assumptions and requires highly abstract spatial reasoning. There's no easily discernible pattern or starting point for many.
• Precise Interlocking Pieces: Each of the 12 wooden shapes must fit with absolute precision. There is no tolerance for error, forcing a perfect understanding of each piece's geometry.
• Complex Combinatorics: While only 12 pieces, the number of potential (incorrect) arrangements is vast, leading to many false trails.
• Psychological Challenge: The puzzle tests patience, perseverance, and the ability to overcome frustration as much as raw intellect.

Reported Solve Time: Varies wildly from many hours to indefinitely. It is NOT a quick solve.

Difficulty Rating: 10/10 (Expert Level - Considered by many to be one of the hardest)
