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 by Stewart and sold on our Marketplace a few years ago, we came across this design thought it was interesting, a fun solve, and a great puzzle to make. Construction came out very well with a Figured Maple Box, African teak top, and Lacewood pieces.
Half Hour Variant ships assembled.

These puzzles are listed as part of the Reserve Puzzle Program: for each newly released puzzle on Cubicdissection, four copies are reserved. After that puzzle is sold out, they are listed one at a time in the next four Marketplace events with a one penny opening bid and no reserve. This is done to discourage profiteering and flipping by making more than one copy available as a competing identical listing.
Our work is handcrafted to very precise tolerances and must be kept within the range of 40-60% relative humidity at all times. Failure to do so may cause inoperability or permanent damage.
