Mega Six 6 piece multiple move burr Standard

Mega Six 6 piece multiple move burr Standard

DIFFICULTY RATING 9 

The puzzle is to assemble the six piece burr.

This puzzle really does show a case of 'don't judge a book by it's cover'.  It may look like other six piece burrs on the outside but it is DEFINITELY not.  The puzzle is incredibly more complicated than the commonly known six piece puzzle. This photo shows the Mega Six when it's about half way together or apart).  msixapart.jpg

Bill Cutler first used a computer program to analyse six piece burrs in 1974 but it took until 1990 to analyse all possible six piece burr combinations. 

Mega Six is the result of that search for the maximum number of moves for a six piece burr with a unique solution.  This does not mean it has a unique assembly, due to the number of internal voids.  In theory the pieces should fit together in 20 different ways however, the reality is that you can physically only put the puzzle together in one of the 20 assemblies.

Not only OUR hardest six piece burr but THE hardest six piece burr!

Dicey Box

Edward Hordern Puzzle Exchange  - Gold Coast, Australia, August 2007
Presented by Bill Darrah.  Made by Brian Young @ Mr Puzzle Australia. Designed by Bill Darrah.

The puzzle is to disassemble and reassemble the 12 piece burr so that all the decorative routing is symmetrical.

The puzzle can go together in two different ways.  One way, without the decorative routing symmetrical, is how the puzzle is presented when sold.  You will have to completely take it apart so that you can then put it back together with all the routing symmetrical. This is a lot more difficult than it may first appear.  A very elegant design by Bill Darrah who is well known for designing very difficult puzzles.

Puzzle made from Mackay Cedar.

Wausau '82 13 piece burr

Wausau '82 13 piece burr

 DIFFICULTY RATING 8

The object of the puzzle is to dissassemble the 13 piece rectilinear burr.  

This puzzle was designed by Bill Cutler in 1982 as part of his Wausau series of burrs.  Prior to this he had worked mostly with the standard six piece burr but this series was an experiment in different patterns of rods along the 3 axes.   Bill describes this second puzzle in the series as one of his favourite designs, saying it uses a lock picking technique.

Decemburr 12 piece multiple move burr Craftsman

Decemburr 12 piece multiple move burr Craftsman

DIFFICULTY RATING 9

There is an interesting sequence of 13 forward and backward moves required to disassemble this puzzle... Yes, that’s 13 moves to get the first piece out and that’s not the trickiest part of the puzzle.

Once completely apart, there are 5485 false solutions (in other words, false assemblies), meaning the puzzle looks like it should go together but you can’t get the last piece in.  Only the specific sequence of 13 moves will allow you to insert the last piece and solve this puzzle. 

This puzzle is made under license to Goh Pit Khiam.
Goh Pit Khiam invented this twelve piece puzzle in December 1999 without the use of a computer.
We’ve given the puzzle a rating 9 out of 10 because it’s sold assembled. 
To solve the puzzle from a disassembled state without clues it could definitely be worthy of a  rating 10!

DIFFICULTY RATING 7

Two of the most popular puzzles ever made and sold in the world have been used to make this unique puzzle.  The puzzle is to assemble both the Soma Cube and the six piece diagonal burr at the same time.

To do this you will need to find just one of the 240 different assemblies of the Soma Cube.  Why? In this puzzle the Soma Cube has a unique solution.  One piece of  Soma Cube is attached to one of each of the pieces of the diagonal burr.  When you assemble the burr you will need to assemble the Soma Cube inside it at the same time. Don’t forget you also need to fit the loose seventh piece of the Soma Cube in as well.....
The concept of putting the two puzzles together came to Brian after seeing a puzzle by Phillipe Dubois made with a single cube loose inside it.

Entrant IPP Design Competition 2004.

Size 95mm x 95mm x 95mm (Each piece of burr 95mm x 30mm x 30mm Each cube of Soma Cube 14mm x 14mm x 14mm)

Packaged DISASSEMBLED for your puzzling enjoyment!  You must rely on the photograph on the accompanying Presentation Card to know what shape to assemble the blocks in. This ensures you'll get the maximum value from the puzzle.  REMEMBER - for when all else has failed we enclose a professionally printed solution sheet.
