“Sierpinski’s Burr is a variation on the traditional framed 6 piece burr, in which 2 opposing corners have been removed. The resulting shape is one I hope you find quite interesting! It adds a few extra moves to the puzzle, and also provides small windows through which possible moves can be deduced. At level 40, it may sound a bit daunting, but keeping track of the solve is manageable, without too many dead ends. I don’t think this one will be the hardest burr out there, but it should be a lot of fun to work out. Of course, the puzzle is named after the Sierpiński Triangle, which the triangular faces of the burr resemble. Pelikan’s build of my design adds a lovely tactile feel, as well as being a beautiful wood combination. I hope people enjoy it! :)”

“This is a wonderful caged 6 piece burr from Tyler. He has been quite prolific over the last few years and has designed several different kinds of puzzle. This is a caged 6 piece burr which has had 2 opposite corners chopped off to allow quite a lot more freedom of movement for the burr sticks. It really adds to the challenge and allows it to reach quite a high level. I loved it but it might be too difficult for many of you if you are nor big burr fans. It has been beautifully made by Jakub and Jaroslav in Mahogany and Acacia. The angles of all those cuts must have made manufacture a bit of a nightmare to produce but the effort was well worth it. Obviously, it needs disassembly and then reassembly.
 
This is a huge challenge but is definitely manageable. There is a particular sequence that recurs several times and each time it is done it allows further progression before being undone and moving other pieces. The entire disassembly is level 40.6.3.1.2.2 so once the first piece is out then the rest will follow quite easily by looking inside and working out what is possible. Tthere was absolutely no way I could reassemble it myself and off to Burrtools I went. So much fun in one small cube!”
