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.

It also features only one solution in a flat 8x8 configuration.Both solutions contain voids making this a very tricky solve and I also made extra cubes that can be used in the solve but not really sure if that helps or hinders your progress? (See last photo)Maple was used from an antique upright piano with Padauk 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...
