Lucky 13 by Alexander Magyarics and made by Nothing Yet Designs. Pack the pieces into the tray.A little about myself and the puzzles. I am a solver / collector.

All the puzzles I sell are solved at least once by me. My home is smoke free and pet free. I keep the humidity where the puzzles are between 40-50% with the average being approximat...

From cubicdissection.com:Six Slabs is a unique packing puzzle reminiscent of the Hexahedroom design. Six uniform "slabs" must be packed into the box, which has three openings in a non-symmetrical pattern. This is complicated by two fixed blocks inside the box. With a level 1.1.9.3.2.3 solution, Six Slabs is non-trivial to solve.Crafted from Curly Maple (box) and Wenge (pieces). Great care was taken during construction, with Wenge accents on the box corners and extremely precise dimensions. Ext...

The artisan half hour puzzle cube (STC-29) by Stewart Coffin. Produced by Eric Fuller at Cubicdissection. This is a pretty straight forward puzzle. The goal is to build a cube. And of corse it was originally named 1/2 hour cube because that’s how long it would take the average person to solve it. Furthermore I will mention that this puzzle doesn’t come with any box or documentation but I did email Eric fuller before listing and I confirmed that it’s and authentic CD half hour cube.

2-in-1 is a twelve piece interlocking burr with a unique solution and a couple challenges; the first puzzle is to figure out what shape it makes, and the second is to make that shape. Ingenious design using full notches makes finding a solution more difficult, as the open spaces concealed in the puzzle allow more false starts.************************************************************For multiple items, combined shipping is available.

The goal of Fano Blocks is to pack seven pairs of identical rectangular pieces flush into the box. These aren't just any pieces, however! They possess unique properties: any two distinct blocks share precisely one edge length in common and any set of two specific edge lengths are held by two identical blocks. The resulting number of edge-matching combinations creates a complicated problem. Finding even one of the eight possible solutions is an accomplishment.Named after the Fano plane (the small...

Eric's description: Slot Machine is a fantastic puzzle, and a ton of fun to solve! Just two pieces dance around each other in the cage...how hard can it be to put them in? Eighteen moves is what it takes, it's a LOT trickier than you expect. A beautiful and fun puzzle.Construction of this puzzle is as good as it gets. The cage ends are milled from solid stock and the cross pieces notched in.

A classic from 1983 that won the Grand Prize in the Hikimi Wooden Puzzle Competition three years later. The objective is to pack the four wooden blocks inside the box. But the pieces are unusually shaped, with some very odd angles. Once you work out the trick to getting that final piece in, you realise there’s a lot of subtlety to those simple looking blocks. This version, crafted by Maurice Vigouroux, weighs 0.8 kg.

A challenging but incredibly satisfying packing puzzle!

From cubicdissection.com:In keeping with our theme of very unique offerings this month, Chain Store is a very unusual puzzle. The goal is simple; to fit the chain with its five interconnected links completely into the box. The solution is not so simple and very satisfying.
