10 of Diamonds award winning puzzle
1 August 2020Made for the Edward Hordern IPP40 Puzzle Exchange which finally took place in August 2023 in Jerusalem, Israel. Originally scheduled for August 2020 but delayed…

The goal is to disassemble and reassemble the 12 H shaped pieces into an interlocked box. All 12 pieces are slightly different to each other which makes the unique level 3-1-1-1-2-2 solution even more interesting to assemble.
Junichi conceived the original design in 1991 and Brian has always wanted to make the H burr as a Limited Edition puzzle but when making a prototype he discovered the original had a number of solutions, some easier than the one intended.
With Junichi working here over the past year it was a good opportunity to encourage him to rework the design. As a result the box burr was born by creating this unique solution H Burr.
The Jarrah (red wood) pieces were added to reduce the solutions to one only. This then also makes the inside of the assembled shape a void, making it a box, effectively a puzzle box that can be completely disassembled.
Wood: Queensland Silver Ash (white wood) with Western Australian Jarrah inserts (red wood). Size: 140mm x 140mm x 140mm Weight: 1.5 kg including packaging.
