Puzzles by Type > Interlocking Burrs - High Level


decemburrapart.jpgThere have been many, many multi-level burrs invented over recent years.  And the speed at which they are being designed seems to have increased its seems with the advent of fantastic tools like BurrTools and more (huge thanks to Andreas Rover for his development of this OpenSource project).  So we thought it would be good to separate these high level burrs on a page of their own.

Burrs are organised by level with the "easier" ones at the top .... bear in mind that absolutely none of the burrs on this page are easy .... it's all relative.  Generally you would have to say a Level 4 burr is theoretically easier than a Level 30 burr but it will still be a hard puzzle!

A level 13.3.5 solution means that it will take 13 moves to remove the first piece. Then only after this first piece has been successfully removed another 3 moves are needed to remove the second piece. Once that is done still 5 more moves will be needed to remove the third piece of the burr.  Very difficult by any standards. 

A move is considered to be a directional move. ie: moving a piece, and sometimes it is possible that more than one piece is moving at the same time, on a single axis in that direction.

Other language we may use to describe burrs "false assemblies".  This is when the pieces would theoretically fit together to make the object shape but there is no physical way of assembling them.  This adds another dimension to difficulty ratings for these puzzles when puzzles are being reassembled. The Mega Six puzzle is a particularly good example of this.




Gordian's Knot very difficult take apart interlocking burr puzzle Gordian's Knot very difficult take apart interlocking burr puzzle


QTY:





The puzzle is to slide each piece oin the correct sequence to take the puzzle apart.
With every move you make, one or more pieces will move easily - but there's only one correct answer.  It's up to you to work out which move is the right one!

This is an extremely difficult interlocking burr puzzle.

This puzzle is so difficult the makers have included a 69 page, one step per page, spiral bound glossy colour solution booklet.  It includes BOTH the solution to take the puzzle apart and also the steps to put it back together again.

 
Halt level 21.8.2 framed burr Halt level 21.8.2 framed burr Out of Stock





Question:  How can getting just 3 pieces out of the frame take 21 moves to get just the first piece out? 
Answer: When it's designed by Stéphane Chomine.
The ends of the pieces are designed in such a way that when they are inside the frame they spell the word HALT around the 4 sides.  But don't let that stop you from having a go at this one.

Edward Hordern IPP Puzzle Exchange - Narita, Japan  August 2013
Presented by Grant Smith.  Designed by Junichi Yananose.  Made by Mr Puzzle.

This puzzle was invented in September 2011 by Junichi Yananose.   It has 6 different pieces and is a unique level 18.2 burr.  With only 6 pieces this means that on average each piece has got to move 3 times to assemble it into the correct shape.  The Coming of Age MkII had 18 pieces and was a level 19 burr;  at the time it was invented it was the most moves for a burr puzzle.  This shows just how far burrs have come in the past 10 years or so.  To top it off this puzzle has a unique solution too!

Our Rating 10/10 from the disassembled puzzle (without using BurrTools). The puzzle comes with a very clear step by step solution drawn by Junichi.

You are choosing to receive the puzzle assembled.  Good value considering he's just spent the last hour putting only 4 together WITH the solution.  Let's hope he gets better at it!
You may have the puzzle for $3 less if you want to assemble it yourself.  Quite a challenge though!  Click here to buy.  Never the less, this puzzle is a significant challenge even just to take apart.

 
Hourglass Osanori Yamamoto level 11.6.3.3 frame burr Hourglass Osanori Yamamoto level 11.6.3.3 frame burr


QTY:





The puzzle consists of single plane frame and 4 identical pieces. Some part of the pieces are actually made from the same wood as the frame and so when assembled they actually look like part of a larger frame.
With the right sequence of moves, level 11.6.3.3, and even rotational moves in the correct place, you can get all 4 pieces out of the frame.   There is only 1 possible solution.  Rotational moves do not mean force.  A rotational move means get the piece or pieces in the correct spot and there will be plenty of space to rotate.

Edward Hordern IPP Puzzle Exchange - Narita, Japan  August 2013
Designed by Junichi Yananose.  Presented by Brian Young.  Made by Mr Puzzle.

The plane is incorrectly assembled and can’t possibly fly like this. You need to take the puzzle apart and reassemble it to make it more aerodynamic. To do that on reassembly you’ll have to solve the level 13.4 multiple move burr.

Good Bon Voyage present.  Plenty of time to play with puzzles on the plane flight!

Our Rating 8/10 because the puzzle is already in an unsolved state (without using BurrTools). The puzzle comes with a very clear step by step solution drawn by Junichi.

It is also available at a small additional cost of $3 already assembled for you.  Good value considering he's just spent the last hour putting only 4 together WITH the solution.  Let's hope he gets better at it!  Click here to buy.  This puzzle is a significant challenge even just to take apart.

Edward Hordern IPP Puzzle Exchange - Narita, Japan  August 2013
Presented by Lambert Bright.  Designed by Junichi Yananose.  Made by Mr Puzzle.

This puzzle was invented in January 2012 by Junichi Yananose.   It has 6 different pieces and is a unique level 10 burr.  The finished shape is very attractive with the two toned wood but having these two different colours does not give any clues to the solution.

Our Rating 9/10 from the disassembled puzzle (without using BurrTools). The puzzle comes with a very clear step by step solution drawn by Junichi.  Sold DISASSEMBLED.

Edward Hordern IPP Puzzle Exchange  - Osaka, Japan  July 2010
Presented by Frans de Vreugd.  Made by Brian Young @ Mr Puzzle Australia.  Designed by David Rousseau.

The object of the puzzle is to take the burr apart and reassemble it.  Just six pieces but beware it's a level 8.3.2.2;  that means it takes 8 moves to remove the first piece, then three more for the next piece, then two more, then two more before it will all fall apart.  The challenge is then to put it back together again.  There are 105 theoretical assemblies, otherwise known as false assemblies,  but only 1 of them can actually be put togetherFor an extra challenge the puzzle comes DISASSEMBLED. 

 
Pylon 2P2C 2 piece 2 column frame puzzle Pylon 2P2C 2 piece 2 column frame puzzle


QTY:





The puzzle is to disassemble and reassemble the 3 piece framed burr.

Designed recently by Turkish designer Yavuz Demirhan in early 2013 this puzzle is unlike the type of framed burr you might be used to doing.

The frame is made of two towers fixed on a base and the puzzle has 2 congruent pieces that can be removed and reinserted into the frame. 

There are 4 possible assemblies but just one solution which is a level 9.9.  That means that it will take 9 moves to remove the first piece then another 9 to remove the second piece.

Edward Hordern IPP Puzzle Exchange  - Prague, Czech Republic, August 2008
Presented by Frank Potts.  Made by Brian Young @ Mr Puzzle Australia.  Designed by Frank Potts.

Status: 30th March 2013. Only 20 left. Once sold we won't make this puzzle again.

The object of the puzzle is to disassemble the burr and then reassemble.  It's a level 9,3 burr but the challenge may not just be about the number of moves to disassemble the burr.

Reviewed as a good "all round" puzzle by someone who says they are not really into burrs http://puzzle-obsessed.blogspot.co.uk/2012/10/sly-burr-frank-potts.html

QTY:





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).  

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!

Cockpit 3 piece framed burr Cockpit 3 piece framed burr


QTY:





The puzzle is to remove the 3 burr pieces from the cube frame and insert them again.

Designed recently by Japanese designer Osanori Yamamoto in early 2013 this puzzle has a very complex level 16.3 solution to solve it with a symmetrical colour pattern.

When the puzzle is completed with the symmetrical light colour bars in place on each face there is just one solution from possible assembles. If the colour pattern is ignored there are 2 solutions from 3 possible assemblies.

The level 16.3 solution means that it will take 16 moves to remove the first piece then another 3 to remove the second piece.

 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, Wausau '82,  as one of his favourite designs, saying it uses a lock picking technique.
