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 ...

We received several requests to remake this classic design by Stewart Coffin, featured as design number 185 in the Ap-Art book and challenged by the author to "Try your luck on this one - or test your patience!" As a follow up to the previous Blind Slot Machine release in 2005, this edition features a clear acrylic window to view your progress during the solve and a removable top panel which will turn the puzzle into a "Blind Slot Machine" which significantly increases the difficulty. Construct...

Feed The Monkey is the first packing puzzle from the (in)famous Two Brass Monkeys collaboration. The goal is simply to feed all the bananas to your monkey so that none are left sticking out of his or her mouth. The solution is deceptive and unexpected, and I think for a first try they have nailed it!The construction of this puzzle is impressive. Solid brass ends cap an aluminum core, with bananas made from very accurate and nicely milled brass stock. The feel and heft of this puzzle speak to its...
