"This ingenious burr was designed by Junichi in May 2007 with "head and hands; no computer". Junichi had the idea for a multiple rotational movement but did not get to finally apply it to a puzzle until he came up with the Tornado Burr.People often ask puzzle designers "What was going on in your head to design this puzzle?" What was going on in Junichi's head when he designed the Tornado Burr? Visualising things going up and down and back and forth at the same time is one thing, but things going...

This clever puzzle shows major design chops. Using four identical, simple pieces and a cage, Yamamoto created a level 9.2.5 beauty with only one solution. Fun to solve, a nice half hour challenge for the serious puzzler. The top and bottom is made from mitred Bubinga component pieces, replete with clever notching to facilitate the inset cross braces. A fine cage if I do say so myself.> Each piece signed and dated; ~30 copies made for sale. Ships assembled.

Like William Hu's "Simultaneous Maze" puzzle , Tamás had made a sequel using two mazes and one pin. Vanyó's design uses an identical top and bottom plate to confuse and trick the solver.An excellent addition to your collection, and a must have to compliment the Simultaneous design.The cage connectors are shouldered and reinforced by lateral connectors. The sliding internal pin has a pair of magnets which keep the slider centered once the puzzle is solved, a nice detail which keeps the puzzle f...

#49 of 100This is a hefty aluminum puzzle with a very special lock. No force, no banging, no centrifugal moves. The object is to retrieve several items inside the puzzle, undo the lock, and then return everything to its original state. Very interesting mechanical design.The reason why this puzzle was titled "Pleasure and Pain" was because, in its original configuration, it was possible to get completely stuck. Solution included. Emergency key to get unstuck (which I purchased from Strijbos ...

One panel of this lock is tight.From Puzzlemaster.ca original description:Made from solid metal, this Trick Lock is more complex than it appears, and unlike regular locks, a key is not the only answer. The hidden mechanism is deceiving and requires a more careful inspection to unlock it. These locks are hand made, there are slight variations in each lock. These are replicas of ancient Indian locks. They are made to look old but are brand new.

The object is to separate the 2 pieces of the cross. Puzzlers experienced with the classical version will find that Strijbos has added an extra element that makes this more difficult. Also, it is produced with very high quality in metal, as collectors of Strijbos' creations are used to.From William Strijbos' original description:I first came up with this idea in early September (2015), actually pretty late In early September! (A company in Switzerland wanted to use my First Cross puzzle as a v...

The object is to remove the heart shape from the box. It's not a puzzle box in the traditional sense, but more akin to the Haselgrove box. The internal shapes must be shifted around correctly to release the heart.When I first got this box, it got stuck inside because the fit was too tight. Brian Pletcher graciously took the puzzle apart, sanded it down so that it worked, and glued it back together. Thanks Brian! The result of all this disassembly and reassembly is that there is a noticeable...

From Eric: Another brilliant Jolly design. Bundle of Sticks is very non-traditional in appearance, and a lot of fun to solve. One stick comes out easily enough. The other three create a set of gates which must be maneuvered before the puzzle can be filly disassembled into its five pieces. The solution is a unique level 13.6!
