Mr Puzzle - We've got puzzles!

Current Category
Puzzles by Type > n-ary Puzzles


Itís not known who first looked at the old Chinese Ring puzzle and thought that the movement of the rings in the solution would have two states equating to on/of or 0 and 1 used in computer binary code.  But they did.  And so a new group of puzzle classifications was made.

Since then thereís been not only binary puzzles, but ternary puzzles where pieces have three states and more. Right up to the current record holder Generation Lock - a 15-ary puzzle. 

Many of these puzzles require a lot of moves to complete due to the recursive nature of the solution. Lucky not many have the number of the Generation Lock  - 341,718,750. Yes, thatís 340 million+ !

The puzzle is to remove the ribbon from the elephant maze disentanglement puzzle.   This is a very nice adaptation of the classic staircase disentanglement puzzle, known in French as Baguenaudier (very appropriately it literally means time-waster) they are closely related to the better known "Chinese Ring Puzzle" or "Devil's Needle puzzle".  Its a type  of "n-ary" puzzle meaning each move has "n" number of state - in this case 2 states being binary.   Read more about n-ary puzzles and see others we have here.
There are 11 different starting positions for the ribbon, rated from "tricky" to "very hard".  When you buy the puzzle from Mr Puzzle it comes with a drawing showing each starting position;  this is only available at this website.
The ribbon can be easily reset by undoing the joining clasp, take then ribbon out of the puzzle, and reset the starting position.

Lock 250 puzzle lock by Jean Claude Constantin Lock 250 puzzle lock by Jean Claude Constantin


QTY:





Designed by Jean Claude Constantin this puzzle is called Lock 250 because there are 250 moves to open... that means another 250 moves to close again.  And that's only if you get them all correct!   The 4 steel sliders on the front move the internal wooden plates of the puzzles and which slider you can move depends on the position of the internal plates.
The puzzle is made from laser cut plywood and the outside is veneered.
We also have the HUGE Generation Lock in stock here at Mr Puzzle with 8 sliders and many, many more moves to solve.

 
Generation Lock over 340 million moves Generation Lock over 340 million moves


QTY:





Designed by Jean Claude Constantin this puzzle is the big (VERY BIG) brother of the Lock 250 also available for sale at Mr Puzzle.  The 8 steel sliders on the front move the internal wooden plates of the puzzles and which slider you can move depends on the position of the internal plates.

Dr Goetz Schwandtner from Germany did an analysis of the number of moves to solve the puzzle and came up with over 340 million moves! 341 718 750 to be exact.  He has published his theory here.  He says that "assuming we employ a group of puzzlers willing to work full time on this lock, without holidays and in shifts, so that the solving is going on 24 hours a day, and 365 days a year, and on average 2 seconds per  move, this will take about 21.6 years".  A big thanks to Goetz for the analysis.

LIMITED EDITION of 30 puzzles released 27th November 2009

November 2011 one of these puzzles was resold on the Baxterweb Puzzle Auction site for USD1250.00. Previosly one had been sold in June 2011 on the Cubic Dissection Marketplace site for USD552.00 (At the time this puzzle was released the original sale price AUD420.00 was equal to approx. USD390.00.)

There are 22 pieces to this extremely difficult caged burr puzzle designed by Goh Pit Khiam.  You'll get a feel for just how difficult it is if you watch Brian put it together on YouTube http://www.youtube.com/watch?v=FKavWv3Jin8.  It took him until he was putting the last one together to get the courage to video it. By this time he had learnt to do it without the BurrTools computer animated solution and do it in about 5 mins. The first one took me a lot longer... a lot... at least 30 minutes with the computer!
