One puzzle that I acquired recently and solved was the Tricolore from Brian Menold and just looking at it how could anyone resist it? In fact looking at the website just now there appears to be a copy still available - you should seriously think about nabbing one now! Go on, I will wait here whilst you buy.....
Back now? Good; I will continue. This is a 6 board burr designed by Frans de Vreugd who is responsible for some of the best board burrs ever including Torture and Extreme Torture (aka Gordian's Knot) with a relatively "simple" level of 184.108.40.206. Brian said this about it:
When this puzzle was recommended to me I was at first skeptical about making it. I love making board burr puzzles but the reinforcing splines were necessary and add to the cost, and, I didn’t know what made it special. Well, was I ever wrong. This puzzle has a few moves in the middle that just leave you saying “Why did I have to do that!” I think it is truly unique. The splines, needed for reinforcement, are a part of the three-color scheme. With a unique solution, it provides quite a challenge; and as I said earlier, some of the moves are, in my mind, quite special. Lacquer and wax finish.Knowing who had recommended this puzzle I just knew that there would be something truly wonderful about the solution. He tends to be fairly skeptical about a lot of the new Burrtools designed puzzles and only when one has something truly exceptional will he say that it is good. As soon as it came up for sale, I nabbed it. Unfortunately the vagaries of Brian's shopping cart system meant that he sold more than he had and I had to wait a week or so for new ones to be made.
