RELEASED:8.14.2014PRODUCED:42 CopiesDESIGNER:William HuCRAFTSMAN:Eric FullerMATERIAL:Jatoba, Maple, AcrylicCOMMENTS:Even though I knew it would be a difficult project, I couldn't resist making this puzzle. It's a very unique concept and execution. The acrylic maze piece must be removed, and the three key pieces are simultaneously manipulated to achieve the goal. Very tricky and very interesting looking, this puzzle begs to be solved.Construction was tricky...the solid side spine and endgrain key...

XMatrix Cubus 3D marble maze. An interesting variation on the metal ball-in-a-cubic maze. Plastic.

Very nice looking carved-animal jigsaw puzzle, not difficult but quite attractive and well-made, with each piece appearing to be hand-carved. Seven animal pieces, plus four frame pieces. The wood of the top and bottom pieces of frame have slight warpage. There's also a detachable bit of wood on the back that can act as a stand for display. I sold a similar puzzle in a prior auction. Weighs 14 ounces, plus about 8 ounces for packing. You can check shipping prices at www.usps.com, shipped from Cal...

This is a simple 3D carved jigsaw of a lighthouse scene (9 pieces) with a 4 piece frame and a backing board. The back has a slotted panel that comes out that allows you to lean it on a desk like a photo. It's pretty, and nicely made, but certainly not difficult.

from puzzlepalace.comThis puzzle is a collaboration between me and Oskar van Deventer. My idea involved two pieces, where the pins of one piece connect to grooves in the other piece and vice verse. The grooves in both pieces should form a maze pattern. After some failed attempts, Oskar simplified this idea to the extreme. Each piece should have just a single pin and a single meandering groove. This way, the puzzle effectively turned into an N.G. de Bruijn "Beer Bottle Problem", see page 373 of "...

I-Scream Sandwich, IPP29 exchange puzzle, from Keith Winegar. A hidden maze with a steel ball - go from one end of the "sandwich" to the other. Ball is captive behind a plexiglass window. Puzzle is maple and walnut. Original wrapper is torn (somewhat unavoidable to get to the puzzle, unfortunately).

A rare and hard to find puzzle from that elusive desiner Roger. This is not a difficult one to solve. The challenge would appear to be to move the ball bearing from one eye to the other. Supplied is a small metal baton to help push the ball around the inside of the puzzle.

Boston has a subway system in which there are two North-South lines crossing over two East-west lines with connections between them at some of the cross-over points. Imagine a future Boston subway system with ten North-South lines and ten East-West lines. Oskar van Deventer imagined such a system and built the most perverse transfer design possible. This rendition of his puzzle was greatly enhanced by the fertive mind of Dave Rossetti who suggested a magnetic wand to guide the intr...

This was an IPP exchange gift from IPP19 in London.

Coin maze is based on a circular maze pattern designed by Adrian Fisher as a company logo. The puzzle is a "misleading" mechanical maze, as it feels that you can cross a wall at some places, whereas you are blocked at other places where there seemsto be no wall.

Multimatch is Wade Philpott's trademark for MacMahon's Three-color Squares, made by Kadon Enterprises. A set of pieces plus a booklet full of puzzle patterns is provided. The classic task is to join squares with colormatched edges plus a uniform border color around the perimeter of the indicated figures. This requirement produces a zigzag sort of region bounded by the border color. Additional activities focus on creating color patches within edge matched rectangles and squares.This original puz...

This puzzle is really interesting. It's a maze with 4 levels and a very unusual property. Because of the size of the cutouts and the round shape of the ball, each level has different paths depending on which way you turn the puzzle. The ball will hit a seeming dead end, but if you flip the puzzle over suddenly new possibilities will appear.VERY entertaining and a really brilliant design by the well known Mr. Deventer. These puzzles are ones from my personal collection that I no longer have ...

This excellent puzzle was an IPP design competition winner. Received in the gift exchange, the craftsmanship is remarkable and the design a ton of fun.

These puzzles are ones from my personal collection that I no longer have room for.Shipping cost will be calculated after the end of the auction. Winning bidder will pay the actual postage amount pl...
