From Eric's write-up: “This is the tricker iteration of the Quads and Rings series. Four wooden burr pieces interlock with three acrylic pieces with a level 17.2.6 solution. Definitely a step up in difficulty from the Q&R1 design; Yavuz has kind of laid the gauntlet down here! Achieving the checkerboard pattern is a second challenge.”For more details: http://archive.cubicdissection.com/html/qnr2.html

From Eric's write-up: “Every time I think I've seen it all when it comes to 4x4 cubes, someone proves me wrong. In thie case it's Mr. Hu with his excellent "Two Wheeled Cube" design. with an odd level 1.1.1.2.8 solution, this puzzle is moderate in difficulty but very high on the fun factor. The first four pieces form a shell around the heart of the puzzle; two identical "wheels" which rotate and dance around each other in a bewildering number of possble states. The meat of the puzzle is figuri...

Six piece typical diagonal burr creating a beautiful shape. Well known Stewart Coffin design but simplified because of the colour symmetry.I made a handful of these for friends and family last year and had this one left over. Great for someone who wants an inexpensive copy of a great puzzle just to actually play with. The pieces are not perfect like a Lee Krasnow or a Peterson work, so you can get some hints as some fit slightly better in certain orientations but the errors are very small so you...

Well known Stewart Coffin design .I made a handful of these for friends and family  and had this one left over. Great for someone who wants an inexpensive copy of a great puzzle just to actually play with. The pieces are not perfect like a Lee Krasnow or a Peterson work but still close tolerances and nice fit all around. Overall it displays beautifully.

Amazing but complicated puzzle. Includes the original instructions.

Six Key Mine PuzzleThe Six Key Mine Puzzle was designed by R.D. Rose and won him a First Place award in the 2003 Nob Yoshigahara Puzzle Design Competition. This version was made by Bits and Pieces and is no longer being manufactured. The puzzle measures 3” across and is quite hefty in the hand. The goal of inserting the six pegs into the sphered centre will have you puzzling for some time.

Aluminum Interlocking PuzzleI am unfamiliar with who designed or crafted this puzzle, It appears that it could be a machinists project as the tolerances are very good and it has been crafted with brass pegs that slide into recessed channels in the pieces. The puzzle measures a little over 3” and I crafted a small walnut base for displaying this puzzle that will be included with the puzzle. The aluminum shows some small scuffs that would benefit from a metal polish but all in all a nicely craf...

This is a 9-piece burr with 4 sticks on one axis, 3 on another, and 2 on the last. I believe I bought this from Puzzlein in '04, their #145. The sticks are 3" long. I have no idea what level the puzzle is.

After looking at a couple dozen designs I chose six for their representation of the various concepts and levels of difficulty.This and the Quads and Rings 1 are probably the entry-level puzzles in this category when it comes to difficulty. Worm Inside is fairly basic, with...
