“The Bermuda Triangle puzzle is a tetrahedral teaser designed to tantalizingly tempt, test, torment and tax your patience to the breaking point.
Designed by Adrian Fisher, the objective of this puzzle is easy to visualize but difficult to achieve.”

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.”
