Oskar's Matchboxes has always been one of my favorite designs. In terms of originality, appearance and overall appeal, very few puzzles come close. The five dissimilar pieces consist of an outer box and inner tray cleverly glued together. The goal is to assemble the pieces so that every tray is contained inside a box. With only two solutions, this is quite tricky!Oskar’s Matchboxes is a very time-consuming puzzle to make, with all pieces constructed using the same shoulder joinery that we used...

Pack six identical pieces into a cylindrical box.  When you close the lid, it cannot touch the pieces!  Each piece is made from four truncated rhombic dodecahedra, also called edge-beveled cubes.  Solving this puzzle is not difficult but requires some "out of the box" thinking!  This puzzle is mentioned in an article in CFF #108 (Cubism For Fun).This is the large version, the rhombic dodecahedra have a diameter of 2 cm.This puzzle is impossible to make out of wood.  OK, not impossible, but ...

Eric says: "The second puzzle in this update by Perez, Board Burr Rack looks quite simple. Simply slide four burrs into the rack spaces created by the frame. Easy, right? Unfortunately the two cubes trapped inside the rack makes that task substantially more difficult. Each board move affects its neighbors due to the two unit size of the cube it's interacting with, creating a shifting maze of confusion. When fully assembled, none of the boards are able to be completely removed witho...

Eric says "I like *some* packing puzzles, and this one made the cut. It's a set of pentominos and a simple box, yet there is only ONE solution to packing them all in. A truly extraordinary achievement! I interpreted this one with a lot of panache, using 12 different woods for the pieces (Canary, Bubinga, Yellowheart, Peruvian Walnut, Paduak, Wenge, Shedue, Mahogany, Ipe, Bocote, Cherry, Ash). The tolerances are very precise, and this puzzle may be a bit tight at first in highly hum...

Eric says "A simple box with simple pieces that is anything but simple to solve. The interlocking solution is a unique level 6.2.3.4.5 which if you're a nerd like me is kind of amusing. There's plenty of room in the box, and with over 40k solutions but only one assemblable, you'll soon be cursing Bram's name. Just remember to blame him, not me. I'm just the woodworker."

Eric says "Elena's burr is an interesting variation with a lot of tricky movement. The level 13.7 solution will keep you very very busy. Disassembly alone is a feat, with lots of dead ends. Reassembly without directions is extremely difficult. Elena's burr is an elegant design, and the ability to come up with a unique solution at such high levels with simple pieces is an achievement. I really enjoyed making and playing with this one!"

Eric says " It's not easy to come up with a new variation on the traditional six piece burr, but Juno came up with a great one! Because pairs of two pieces are off-centered, the assembled shape of the puzzle looks inaccurate though the pieces need to be accurate. The puzzle is based on one of the notchable sets of a level 9 combination. Thanks to the off-centered pieces the puzzle has unique solution and is very confusing to assemble! Construction of this puzzle is perf...

Eric says "The Loopy Burr came from the genius brain of Junichi; a very unusual six piece interlocking puzzle with pieces that form three intermingled loops once in the proper position. Finding that position takes eleven moves, and is downright tricky due to the space caused by the loops. Good luck! Construction of this puzzle is outstanding, with our usual precision down to several thousandths of an inch."

Pack six identical pieces into the hexagonal box.  Each piece is made from four rhombicuboctahedra.  This puzzle looks quite different from the (large) version, but the solution is the same.  Solving this puzzle is not difficult but requires some "out of the box" thinking!  This puzzle is mentioned in an article in CFF #108 (Cubism For Fun).This is the small(er) version, the rhombicuboctahera have a diameter of 16 mm.This puzzle is impossible to make out of wood.  OK, not impossible, bu...

"This is the 2nd version of the Byway Secret series. There are 2 rooms inside, and you'll be able to open the 1st room soon. But, it takes 10 moves to open the 2nd room, and you'll miss your way to open. The right side and the reverse side will intertwine and move each other. It was made with a new mechanism that is an application of traditional Himitsubako's bar device."Includes original box and solution.------------------This is one of the hardest Karakuri I have solved - the 2nd compartment i...

"A participant of the 2010 IPP Design Competition, this devilish take apart puzzle is not for the faint hearted. It's extremely difficult to open, and even more difficult to fully understand. The mechanism is simple enough, but figuring out the exact principle is difficult. The goal is to simply open the egg and remove the "yolk" (in this case a US quarter coin). Individually manufactured by Robrecht in the EU, this puzzle is fairly heavy and very solid. It will not be mistaken for a mass produc...

A science toy, not really a puzzle, except to figure out how it works. Blowing into an opening in the side of this flying saucer shaped object turns a turbine that makes the toy a gyroscope. Includes stand as shown and includes instruction booklet. Made of iridescent polymer plastic and measures about 3 1/4 inches in diameter.

The goal is to arrange the eight square pieces so that adjacent colors match.

This clever puzzle is composed of 9 cubes and a frame. The cubes have some sides with portions of Escher images, other sides are clear and reveal an internal mirror that can be positioned to display adjoining images. The cubes must be aligned correctly to display the proper image. A counter-intuitive twist on the sliding-block category of puzzles. Blocks can be rotated to result in one of five different drawings by M.C. Escher. Measures approximately 5 x 5 x 1.25 inches. Copyright 2008 by Recent...

This is one of a series of locks I am selling. Mostly (all?) Indian manufacture and best described as "rustic". All are in working condition,  none are particularly tricky. Condition is variable on most of these. Oil, Grease, Rust all present in varying degrees on these locks.  If you have ever bought locks from India (as I did) you should know the kind of thing you are getting. A puzzle you have to wash your hands, or your Standardised Puzzle Hamster's fur after using,.My standard puzzle hams...

Autumn Rush by Kel Snache. Purchased from Puzzlemaster of Canada.  Overall a nice puzzle, though the sides are slightly warped.  I've been told and shown that other copies have some wood warping as well.  Pictures included for full disclosure.  Paid $199 (CAD) = $139 (USD).  Item is sold-out and I've discounted the puzzle 25% if somebody wants to give this one a Go!Not to be used to store anything inside as the opening mechanism takes up all the space inside of the box.  Received in new c...
