Not Curly Burl – Curly Burr N8

I like all sorts of puzzles, but I still consider myself to be a burr guy.  As such, I always look forward to Frans de Vreugd’s International Puzzle Party (IPP) exchange puzzle every year.  This year’s puzzle, Curly Burr N8, was designed by Frans himself and made by Pelikan using Maple and Merbau.  Should have been Curly Burl Maple – just sayin.  However, one of my pieces is curly on the end.

The information that comes with the puzzle indicates that it has a unique level 8 solution.  This means that it takes 8 moves to remove the first piece from a fully assembled puzzle.  Unfortunately (or fortunately), it comes unassembled and there are quite a few required moves before the last piece gets put in.  And they forgot to mark the piece the goes in last.  Of course, being the expert burr puzzler that I am, I started with that piece as the first piece.

I always enjoy solving 6 piece burrs.  I start by taking the pieces and examining them.  Each piece is new and has its own specific role to play in the solution dance.  This ensemble has a pair of twins, which helps to reduce the complexity a bit.  While experimenting with the pieces, you develop a feel for how the notches and nobs are used and given the nature of these particular pieces, how the pieces have to move to start a disassembly process.

I worked on one assembly for a while, but was not able to get to the finish line with it.  As difficult as it is to break away from a potentially promising assembly, I reversed some of the pieces to successfully solve the puzzle.  Along the way, I discovered that the piece that I started out with needed to be the last piece, and I found it a bit of a dexterity problem to hold all the pieces in place as I juggled the remaining pieces to swap it out and then reintroduced it later.  Once it was added, it was just a matter of manipulating the pieces to close it up.

This puzzle does have a red herring.  I was continually puzzled by an aspect of one of the pieces.  After solving the puzzle, I was left wondering if it had been used without me noticing it.  So, I carefully disassembled it while keeping a close eye on this piece and I was left with the impression that it had more capability than was being used.  Next, I looked at all the pieces.  It was then that I realized that this feature was not there for the solution but for the manufacturing.  I approve - well done!

As of this writing, there are still copies available for purchase on Pelikan’s website.  If you are a burr person like myself, I highly recommend getting it.
