Fidget burr was an easy decision to make. A seemingly simple 3x3 cube, it's actually a five-piece interlocking burr with a level 12 solution. Three burr pieces nest inside two identical frame pieces. Disassembly of this puzzle is VERY tricky, with many false paths and dead ends.  Fidget Burr is a ton of fun and it turned out very well.The cage pieces are made from Cherry sapwood, and the internal burr pieces are made from Wenge.These puzzles are extras and oddballs that have accumulated in the ...

Numlock is an n-ary puzzle designed by Pit Khiam Goh and crafted by Johan Heyns with help from Jack Krijnen.  Theoretically, the puzzle could be increased to any odd-number-ary size (Johan has made a 7-ary/9-ary version) this ternary/quinary option was quite enough for me!  The toughest setting will need 404,999 moves to release the first piece but I will ship it in the more modest 47-move setting.  Please read Kevin Sadler's excellent review at https://www.puzzlemad.co.uk/2017/11/not-jingly...

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...

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 ...

This is a great puzzle box designed by Bruce Viney of Homemade Puzzles.  I built this puzzle box myself.  It has very little tight spots.It is made of 1/8" plywood.  I sanded it to a very smooth finish, with Sandpaper 6000 grit.  It is unfinished.  I will send the sequence to opening it, as it has a secret area in the box, and it takes 42 moves to get to it, with 42 moves in all.
