“Effectively a large burr puzzle which contains 36 identical pieces. The Herculean strength required here tends to be more mental rather than physical”

This puzzle does not come with a solution.

Pentangle says ~
“Almost all of our puzzles are supplied without solutions. We feel that if a solution is sold with the product - the puzzler will look, often without really trying to solve the problem first! We do however, offer a solution service whereby the ‘answers’ are available upon request.”
