“When two of my favorite puzzles designers get together to collaborate on a new puzzle, I take note and anxiously await the arrival of the final product. The dynamic duo for this most recent venture is Christoph Lohe and Andrew Crowell. Chris prototyped a puzzle design concept with 3 interlocked burr pieces within a 5x5x5 frame and provided Andrew with this new raw puzzling material to inject into his magical complexinator. The complexinator then churned this puzzle DNA into several new creations. The best of these creations are the Chamburr and Cyburr twins. If you solve both, you will notice some similarities but also appreciate the differences. Normally, I like to receive puzzles from Chris and Andrew unassembled, but I was more than happy to get these assembled. Chamburr requires 43 moves to remove the first piece! A disassembler’s dream with the pieces endlessly dancing around each other. If you are familiar with Andrew’s complexinator you may be tempted to rotate the pieces but avoid the temptation. All 43 of the moves are strict rectilinear moves. However, if you are tempted, it is possible to remove a piece halfway through using rotations. Once the first piece is out, a quick rotation will release the other 2. If you think that the lack of required rotational moves to remove the first piece would make Chamburr easier than Cyburr, you would be wrong. I found Chamburr to be the more difficult of the two. If you are bold and scramble the pieces before reassembly, you will have a formidable challenge. Cursing is permitted on this one.”
