Description

I have decided to offer up this puzzle in an effort to further thin out my personal collection.

This is a clever design by Stewart that is nicely made by Henry, which was presented at IPP 25 in Helsinki, Finland marking his third participation in the Exchange.

Stewart wrote:

“Six polyomino pieces fit into a 3x3x3 box that has a cubic block attached to the top midpoint of one side, hence the name. It was presumed to have only one solution, but I was never sure until Bill Cutler confirmed it by computer.”

Shipping cost to be determined at close of auction.

Pentablock - Stewart Coffin Design #2 by John Devost

Tube It In 2 - William Hu by John Devost

I’m sure everyone is quite familiar with William Strijbos’ original Tube It In design so I don’t think I need to give a lengthy description but should say that William Hu came up with a novel design twist on this awesome puzzle and he has graciously allowed me to make a small run.I’ve long since left the puzzle scene after completely retiring, however I did finish up a select few of these and thought I’d offer them up for sale.This puzzle is crafted from Padauk with Yellowheart Slipfea...

Gouge Packing Puzzle - Gaétan Gouge by John Devost

I previously made a few of this surprisingly difficult packing puzzle by Gaétan and at the time I didn’t have any contact info for him but then a few years ago I was surprised by one of his puzzle purchases in ‘Paradise’.My plan was to make another run but life kinda’ took a turn so now I’ve managed to sort myself out and began making another run.Allard kindly blogged about the copies I made in 2014, here’s an excerpt:https://allardspuzzlingtimes.blogspot.com/2014/04/gouge-packing-p...
