Houses and Factories, designed by Dick Hess, produced by Bits and PiecesGoal of this puzzle is to pack the two houses and three factories into the square frame.  It's a nice looking metal puzzle and a fair challenge.  The puzzle was an entry in the 2004 Design Competition and also an exchange gift at IPP24.  A brief review can be found:http://mechanical-puzzles.blogspot.com/2010/05/puzzles-at-museum-of-science.htmlPuzzle will come with its original solution sheet.-----Buyer is responsible for...

This Burr looks like it's made from 3 pieces (hence the name), but is actually a non-standard 6-piece burr.  Made by Bits and Pieces, it is still new and in shrinkwrap.  Will be provided with its original box and solution sheet.  Online, I've also seen this puzzle called "Triple Play".-----Buyer is responsible for shipping which should be less than $10-12 for small puzzles (within USA, first-class).  Priority mail (and heavier items, such as the glass puzzles) might be $3 to $6 more.  I cha...

Climburr is a very special collaborative design effort by Chris Lohe, Ken Irvine and Andrew Crowell.  Building upon the previous  designs by Chris that featured three sticks in a 5x5x5 cage Chamburr and Cyburr this design is on a whole new level. Here is what Chris says about it: "Climburr is not really a 5x5x5 framed puzzle any more. In order todisable an early shortcut it requires an odd angled cut in the frame,and two angled cuts in one of the three Burr sticks. It pays back by a50+ level...

While ResQ and Jammed Gem share a few similarities, Jammed Gem takes a different approach to deny the solver. We can't say more without revealing spoilers, but ...

Stewart Coffin designed the venerable Half Hour puzzle in 1975, so named because he thought it would take most people about that long to solve it. This variant of Half Hour, STC-29B, is a spin on the classic design. The box features a removable top panel that dovetails into the restricted opening for storage of the solved puzzle. Solving the Half Hour cube will only get you partially there, as the "T" shaped restriction limits the assembly to one solution.Previously existing as a prototype made ...

The two board and two burr pieces interact with the two hybrid-style pieces to create an unusual challenge. The solution is devious and clever.Construction of Exhaust went very well. The end-grain joints of the hybrid pieces are reinforced by a half-shoulder for strength, ensuring that this puzzle will stand the test of time without mechanical failure. Exhaust look...
