Twelve Points to Insanity burr
12 October 2022Standard Range version made from April 1995 – current. Made 2300. These puzzles are still available in our eBay shop. https://www.ebay.com.au/itm/252288742855 The puzzle is to…
12 hexagonal sticks & 12 dowels. Six stick-dowel pairs joined to form six elbows. 18 pieces in total.
Aka “The Monster”. The more elbows the harder the puzzle.
Stewart theorised that the maximum number of elbows that can be joined before assembly becomes impossible is half the number of each type of piece, so that’s what Brian has done.
Brian has built the puzzle in the reverse direction to Stewart’s drawings, after all we are downunder. Stewart noted that the lattice structure repeats itself indefinitely in all directions, so it would be possible to make larger assemblies with more and longer sticks and dowels.
Size: Hex pieces are 140mm long.
