You want a really hard puzzle? You want a puzzle to really stump the person who can do them all? This is it.... a list of all our really challenging puzzles. Our most difficult puzzles all on one page. Mr Puzzle Australia makes and sells some of the hardest puzzles in the world. Some of the the really hard puzzles are made here in our own workshop and are not available anywhere else in the world.
We consider a hard puzzle to be a puzzle that will take some hours to do and memorise. We don't consider a puzzle mastered until you can show someone that you can do it without them getting bored half way through the performance. These very difficult puzzles may be a challenge but being difficult to us doesn't have to mean just more pieces...
You'll find these puzzles interesting as well as difficult.
Edward Hordern IPP Puzzle Exchange - San Francisco, USA, August 2009 Presented by Frans de Vreugd. Made by Brian Young @ Mr Puzzle Australia. Designed by Jack Krijnen in 2008.
Jack Krijnen has invented a number of different 18 piece burrs in the past few years but this one stood out from the others. The puzzle has 29467 possible assemblies.
To assemble the puzzle in this symmetrical colour combination the puzzle has a unique solution. This solution is a level 62 disassembly; this means that it will take a minimum of 62 moves in exactly the correct order to remove just the first piece. The puzzle requires a total of 105 moves to remove all pieces and take it completely apart. The number of moves to remove each piece in order is first piece - 62 next piece - 4 next peice, then 21 next piece 1 and so on - 2.2.1.1.1.2.2.2.1.1.1.2.
We cannot stress enough how hard this puzzle really is - that's 105 moves in exactly the right order as a computer would solve it and along the way you will find that there are many, many moves you can make which will lead you in completely the wrong directiion.
In almost 20 years of manufacturing puzzles for a living Brian says that Condor's Peeper is up there as one of the hardest puzzles he has ever had to assemble. The only one that he remembers being harder is Puzzlers Cage http://www.mrpuzzle.com.au/category103_1.htm which he made as a Limited Edition in 2002. At least he only had to make and put together 24 of those!
The puzzle is to separate the four pieces from each other then put them back together again. Even when you think you've almost got it there's another secret to unlock... and then there's the problem of putting it back together.
Can you take the three pieces of the puzzle apart? Can you get the puzzle back together again? There are three interwoven pieces to the puzzle. Can you separate each piece of the puzzle?
Separate the 4 pieces of the puzzle. True bonds has always been hard to form, but once formed such bonds are eternal and hard to break. The inventor Uyematsu says that his original version was created with this image in his mind, but the puzzle was completed into a cast puzzle with a bond that is truly difficult to unravel. How would you go about breaking and forming this bond? There are two approaches to this puzzle and we challenge you to both!
The three pieces of this puzzle just slide apart, you don't need to force them. Can you work out the twisting movement required to achieve this and to then get them back together again?
Can you separate the three links of the chain and then get it back together again? What's special about this puzzle is that it can be solved three different ways, depending on which of the three pieces has been chosen as the middle link.
The object is to separate the two parts - N E W S. The level of difficulty is very high because it's very difficult to work out the solution to the puzzle. Once done the puzzle is not difficult to memorise.
There are two goals to the Cast Nutcase created by the Dutch puzzle inventor, Oskar van Deventner. 1. Remove the small nut by disassembling the Cast Nutcase. 2. Cast puzzle enthusiasts (some call them nutcases) can enjoy trying to change the wording on the bolt from "nut-case" to "case-nut".
The puzzle is to assemble the 31 blocks into the planet Saturn with it’s ring.
The puzzle is similar in concept to the Rubik’s Snake but it’s been connected into a complete ring.The puzzle also has a combination of right angled pieces and some straight through pieces to make it more challenging.
What a great Christmas present to commemorate the release of the Huygens probe from Cassini on Christmas Day 2004.

The blocks are strung on a closed ring of strong elastic cord so it’s difficult for you to find where the puzzle starts and ends. The puzzle was designed by and is exclusive to Mr Puzzle.
We also have a couple of copies of this puzzle on our Collectibles page as part of "Juegos de Ingenio" magazine plus Mr Puzzle designed Saturn Ring set. Click here.
The puzzle is to re-pack all 9 pieces in the box so that all pieces are under the closed lid. You will need to make room for the key (dowel) to fit.
Mr Puzzle resdesigned Make Room so that this version has a unique solution.
The puzzle is made with the kind permission of Stewart Coffin. At IPP21 in Tokyo in 2001 a larger version of the puzzle #127-A was given by Jerry Slocum as his exchange gift. That version had 14 separate solutions to fit all nine pieces in the box. Click here to view this original design by Stewart Coffin.
As well as our Standard Range this puzzle is also available Craftsman Range made using 9 different Australian hardwood timbers.
