6-piece Burr puzzle

July 2007

(Pictures of my creations can also be found in my BrickShelf folder)

1. Introduction

I always wanted to build a Burr-puzzle, too. But I didn't want a puzzle with one solid piece (without a single cutout), because these are rather easy to solve. I found an interesting webpage with lots of precalculated six-piece Burr puzzles. I decided to try to build the level 2.3 puzzle designed by Stewart Coffin. There are more difficult puzzles too, but I had to bear in mind that I had to be able to solve the puzzle by heart (in front of an audience).

  • Right: the pieces. The piece on the right was a very difficult one to create: because of the many cutouts it was really hard to have this piece smooth on all sides (with no visible top or bottom of LEGO elements).
Required pieces

The first time this puzzle was shown to the public was on August 10, during the 75th anniversary of LEGO. Apparently, Michael Brandl is a puzzle freak too: all day long he begged me to give him the building instructions for this puzzle. So don't be too surprised if you see this puzzle appearing in his collection soon.

3. YouTube video (2015)

Better late than never: I finally made some videos of my sliding puzzles, posted them on my YouTube channel, and embedded them here on my website.
Unfortunately, by the time I made those videos this puzzle had already been taken apart to built the bigger 18 piece Burr.

The rendered images are created with MLCad and rendered with POV-Ray.
