Multiball is a tricky new puzzle box with a deceptive solution. Four stainless bearings are trapped behind a small window, and must be dealt with to open the box. Panels slide, pins drop, and the box remains stubbornly closed. There is one and only one way to open this box...can you figure it out? The solution will not be what you think!Construction of this puzzle is excellent, with sturdy shouldered joinery and a precise fit. As with all puzzle boxes, Multiball should be protected against abrup...

Missing Notch is one of Stewart Coffin's more difficult assembly puzzles. The six pieces are nearly identical, with notched out centers and two angled notches on the outside. One piece is missing an angled notch, which obviates the obvious coordinate motion assembly. Can you figure out the alternate methodology?This puzzle came out very nicely, with a precise fit and a solid maple cube with magnets on each face to keep the inherently unstable assembly together once solved.57 copies made for sale...

Rick sent me this design a while ago and initially, I wasn't going to make it...all those holes are incredibly time-consuming to drill. He stepped in and helped with the drilling, so this is a true collaborative effort between designer and producer.Logical Progression is a very unique cube. With only one solution which must be accomplished with serial assembly, it seems at first look that this puzzle will be a trial and error nightmare. However, the puzzle is designed such that scrutiny of the p...

An interesting and unusual interlocking burr puzzle designed by Tom Jolly. Six identical pieces interlock in a symmetrical manner. Moderate in difficulty and fun to solve. The "H Cube" takes this same concept but bumps the difficulty up several notches in assembly and disassembly. Seller is responsible for all paypal fees. 

A Stewart Coffin classic; fairly easy to make a shape with, a bit trickier to discover the single symmetrical solution. Very nicely made by John with exotic hardwoods. Seller is responsible for all paypal fees. 

Another brilliant packing puzzle by the designer of the award winning "Casino" puzzle, Harun is a tricky assembly. Six notched sticks and six small planks pack into the box two different ways. The solution is trickier than is apparent given the simple pieces.Construction of this puzzle is excellent, with a precise fit which displaces a cushion of air when the entire assembly is dropped in at once.56 copies made for sale, each signed and dated.

Eric's description: Pin Block Case is a unique and very interesting packing puzzle. It's not terribly high level, nor super difficult, yet there's something satisfying about the solution that makes it a wonderful puzzle. Construction of this puzzle is very sturdy with milled, solid pieces.

Never got around to playing with this good looking Alfons Eyckmans’ puzzle.  Solid weight to it with perfect fit.  Getting away from burrs these days, otherwise this would be aback in my shelf. Level: 12.10.6.1.2
