Geneva is the first new puzzle by William Hu in quite some time. Named after the clockwork mechanism that it's partially inspired by, the level 9.3.4 solution includes some very unique rotations and coordinate motions. During assembly, there's a fair amount of freedom, with a lot of dead ends to run into and circles to run around in. Geneva is a nice addition to any TIC collection.This puzzle is shipped disassembled.Precision wood puzzles can be damaged by environmental changes. Please read the...

Designed and first released at IPP in 2009, Surround is closely related to the 3/4/5 cubes designs by Ichiro. In this case, six pieces must be used to surround the solid cube in such a way that is self-supporting. Two solutions using magnets are possible, with another "rule-breaker" solution that does not use magnets and covers the cube completely! The finished shape is pleasingly symmetrical and displays well.Puzzle Pusher has an excellent blog review of this puzzle.Precision wood puzzles ...

Five is the magic number! This "Turning Interlocking Cube" has a level five solution, with five rotations and five different wood types. Designed by Andrew Crowell, these fascinating TIC's take it to the next level. Instead of straightforward linear moves, these designs require rotations during the solution process. Construction is outstanding, with shouldered joinery where side grain gluing is not possible, and detailed bevels which flow around the shouldered joints for a uniform appearance.Thi...

Irregular board burr by Yavuz Demirhan. I do not have a definite record of the wood species, but I believe they are Maple, Padauk, Wenge. Shipping is from California, USA. I will ship worldwide; buyer to pay actual shipping costs.

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...

Boron is a moderately difficult puzzle that displays like a piece of sculpture once it's solved. The 12 pieces are made with contrasting hardwoods and precision-crafted in our North Carolina workshop. Its interlocking nature means that several pieces have to shift around to release the first piece. This puzzle is a lot of fun and a great addition to anyone's collection, beginner or advanced. Boron is delivered disassembled.For multiple items, combined shipping is available. Simply message me on...

A small but good-quality set of 13 length-8 burr pieces. (From the photo it looks as though a piece is missing, but the set is complete; it is a 13 piece set that comes in a box that could hold 14.) Craftsmanship is solid but not top-tier. Excellent condition. Shipping is from California, USA. I will ship worldwide; buyer to pay actual shipping costs.

Another classic by Oskar van Deventer, the Paperclips puzzle is rarely made, and for good reason. The length of the sticks and small surface area for overlap at the edges makes it very difficult to construct. Each corner is reinforced by a shoulder joint, then sanded flush and further reinforced with a full length spline. This is a very time consuming process, but is the only way to ensure the strength and rigidity necessary for this work of art.The result is worth the effort. With two possible ...

Derek's Split Maze Burr has been eagerly awaited as the more difficult and imposing version of the original Maze Burr released years ago by Kagen. Upping the ante with double maze plates on each face, this puzzle is more of a puzzle system. There are many challenges, with "simple" solutions requiring 30 moves up to the most difficult configuration requiring over 300 moves to solve! The puzzle comes with tools to rearrange the plates and a downloadable booklet illustrating the problems (a link to...
