The Gift That Keeps Giving - The Ottawa Cube

Several years ago, the hosts of the 35th International Puzzle Party indicated that they liked my 4x4x4 interlocking puzzles and asked if I would be interested in designing the Committee gift for IPP35.  This gift is given to each of the hard-working committee volunteers that make the event run smoothly.  Of course, I was honored and immediately said yes.

The development of the IPP35 puzzle was a collaborative effort between several people including the IPP35 hosts, Brett Kuehner and Rob Stegmann, who provided design criteria, reviewed proposed designs, and provided feedback; myself as the designer; world-renowned craftsman Brian Menold from Wood Wonders to make them; and Rob Jones providing support.  The result of this team effort was the Ottawa Cube.

What prompted me to finally write about the Ottawa Cube this week, is the listing of an Ottawa Cube on the Cubicdissection Marketplace.  Only 30 were made and you don’t see them very often.  This particular copy is an unopened spare from IPP35 that has been added to the puzzle auction to support a charity: Community Food Bank of New Jersey.  The winner will not only support those in need but end up with a rare puzzle as well.

Since it would be awkward to describe how wonderfully awesome this puzzle is, I decided to share some of the highlights of the design process:

Round 1 - Something New

The IPP35 hosts approached me 1½ years before the event to design the puzzle.  They were looking for something similar to my 4x4x4 designs and offered the following criteria:

• It should be a new, unproduced design.
• It should not be too expensive to make.
• It should be challenging but not too difficult to solve.

With that guidance, I set about creating 3 new designs and I brought prototypes to IPP34 and the following Rochester Puzzle Picnic (RPP) for the hosts to review.  Each of the designs consisted of a 4x4x4 puzzle built around an initial concept.  These concepts were:

• An entire 2x2 face pushed in for the first move.
• A friction move required for the first move.
• A puzzle consisting of all U-shaped pieces.

After a thorough review by the hosts, they said that’s nice, … , but it’s not what we’re looking for.  They were looking for something more theme related to IPP35 in Ottawa, Canada.

I dubbed the 3 designs - The Reject Series, and they are now even rarer than the Ottawa Cube.  There are only 3 complete sets and I have one of them.

Round 2 - Something Themed

Armed with a pocket full of rejection, I thought about how I would approach a themed puzzle.  I pretty quickly decided on a cube with letters on the side with the following criteria:

• The cube would have to be 5x5x5.  A 4x4x4 cube was just too small and anything larger would be too expensive.
• All the characters used would be on the face of the puzzle and not hidden inside.
• It would be done in two colors with red for the foreground and white for the background to match the Canadian flag.
• Each piece would be a single color and not a combination of the two colors.  Yes, sometimes I like to make things unnecessarily complex for myself.  However, without this restriction, you could take any 5x5x5 puzzle and make it look the way you want and I felt that it would lose the quality of what makes it unique if that was done.

I worked up an initial prototype using live cubes and sent pictures to the hosts for an initial assessment to verify that I was on the right track.  I was glad to get a response back that it looked worth pursuing.

Round 3 - Something More Complex

Unfortunately, there was no way to lay out the letters on the face where the adjacent edges matched color.  To solve this dilemma, I had to up my game and cut the corner cubes at a 45-degree angle to get a different color on each face.  Of course, this was no longer a cubic dissection and I realized that I had probably just shot the expense criteria to hell.  

Did I mention that I imposed a restriction where each of these different color cube halves can’t be part of the same piece?  Needless to say, it was a challenge to develop an interlocking puzzle with purely colored pieces.

I created a BurrTools file of the new design where each cube in the puzzle was represented by a 3x3x3 set of cubes to allow me to cut them in half at an angle.  BurrTools was able to successfully solve the puzzle, which is always welcome feedback.

With a bit of trepidation, I sent the BurrTools file out to the team for review.  I was particularly worried about what Brian would have to say about all those 45-degree angle cuts.  As an amateur wood dabbler, it looked insurmountable to me.  

Round 4 - Final Product

With the design process complete, Brian Menold took over the development of the Ottawa Cube. Aside from some recommended changes to improve the structural reliability of the pieces from Brett and Rob’s review of an initial prototype, it was good to go.  Rob also suggested the name: The Ottawa Cube.

The final product is a gorgeous cube with the letters for IPP35 on 5 of the 6 faces.  It’s made with Redheart and Maple to represent the red and white colors of the Canadian flag.  It’s also fairly big and heavy at slightly over 3” per side.

When I first saw the Ottawa Cube at IPP35, I was amazed on how beautiful they looked and how smoothly they moved.  Brian did an amazing job with the 45-degree angled pieces and I was impressed on how well everything came together.

I’m sure that Brian has his own story to tell about unrealistic designers and constraints.  After everything was done and I chatted with Brian about the project, I thought I heard him mumble something under his breath like “neber eggen”.

I’m glad to have been part of The Ottawa Cube team and thoroughly enjoyed working with the team.  I hope that others will be interested in acquiring a copy and helping support the Community Food Bank of New Jersey by bidding generously on the Cubicdissection Marketplace Ottawa Cube listing this week.

A Second Chance – Puzzle Auctions

Wausau '82

You’ve just read about a fantastic puzzle that you failed to acquire.  Maybe you weren’t interested in it when it was released, maybe you couldn’t afford to buy it with all the puzzles you wanted at the time, or maybe you’re just getting started and arrived too late.  Now your friends are telling you it is the best puzzle ever and what a shame that you missed out.  The puzzle community is rife with regrets regarding missed purchase opportunities on limited edition puzzles.

Regret is a constant itch that can be scratched with the help of puzzle auctions.  It is a second chance to acquire that puzzle that will complete you.  I always track the auctions looking for puzzling gems that would add shine to my collection.  I’ve acquired several puzzles through the auctions including a couple of Bill Cutler’s Wausau series puzzles (‘82 and ‘83) made by Mr. Puzzle and several Cubicdissection puzzles that I failed to buy when they came out.  (Note: Wausau ’82 and ’83 are currently available at Mr. Puzzle and Wausau ’82 – ’84 are available again on Bill Cutler’s site ). The puzzle auction sites that I track are:

Wausau '83

• Baxterweb Puzzle Auction – This puzzle auction site, run by Nick Baxter, is held a few times during the year and lately has been concentrated in the Winter months.  I believe that the puzzles being auctioned are in Nick’s possession (therefore shipped from the US) and he provides the photos and descriptions along with an estimate of what the puzzle is worth.  Bidding utilizes an anti-sniping feature set to 24 hours.   For those of you not familiar with the term sniping, it refers to the action of a bidder to place a bid just before an auction ends to ensure that the prior winning bidder does not have an opportunity to reconsider and increase his bid.  The anti-sniping capabilities added to many auction sites were added to avoid this by extending the auction for a period of time after a new highest bidder has been established.

• Cubicdissection Marketplace – Run by Eric Fuller, this puzzle auction site runs several times during the year.  Before the auction starts, any registered seller can add items to be auctioned.  The sellers provided the descriptions and photos and the puzzles are shipped by the sellers from their location to the winning bidders.  Bidding utilizes an anti-sniping feature with a variable time delay that decreases over time to avoid long extensions for the auction.  It’s 24 hours for the first 3 days.

Jupiter

• eBay – Sometimes, very nice puzzles show up on eBay.  I acquired my copy of Stewart Coffin’s Jupiter puzzle on eBay.  Anybody can list a puzzle on eBay at any time so you either have to hear about it or establish search criteria that will periodically email results to you.  All listing information is from the seller and the puzzle will be shipped from the seller’s location.  Sniping is rampant on eBay, so make sure you bid appropriately.  Puzzles can also be listed with a buy option.

• Haubrich Puzzle Auction – This puzzle auction site is run by Jacques Haubrich and runs several times during the year.  I believe that the puzzles being auctioned are in Jacques’ possession (therefore shipped from the Netherlands) and he provides the photos and descriptions along with an estimate of what the puzzle is worth.  Bidding utilizes an anti-sniping feature with a variable time delay that decreases over time to avoid long extensions for the auction.  It starts at 24 hours and only existing bidders on an item can continue bidding during the extension period.

• Puzzle Paradise – This site is like eBay for Puzzlers.  It is supported out of the UK by a group of puzzling individuals that generously donate their time to support the site.  Puzzles can be listed at any time by registered sellers, who provide all listing information, and the puzzles ship from the seller’s location.  Puzzles can also be listed with a buy option.  Puzzle listings may indicate that anti-sniping is activated and how it operates.

Keep in mind that shipping is usually not included in the bid price and you may want to factor that into your bidding process, especially if you are bidding from overseas.

Please be respectful when participating on these puzzle auction sites.  The site administrators work hard to make these valuable facilities available to the puzzle community.  They can and will bar troublemakers from participating at their discretion.

This post was motivated by the 2 major puzzle auctions going on this week at the Cubicdissection Marketplace and the Haubrich Puzzle Auction.  When checking out the Cubicdissection Marketplace, be sure to look at the puzzles being offered by an anonymous seller identified as Steve (there’s a Big clue here somewhere on who that is).  In a stroke of brilliant lunacy, Steve has standardized weight and size measurements for puzzles utilizing the Standardised Puzzle Hamster (SPH).  All puzzle vitals are provided in SPH and each puzzle photo is taken with the SPH for reference except for the ones that the SPH was too embarrassed to be seen with.  For those using antiquated systems of measurement, the conversion to 1 SPH is 160mm length, 76mm height , and 64g weight.  The puzzle descriptions are a must read and not to be missed.  And the best part – One of the puzzles that the SPH is squatting on is Wausau ’83!

Bid well and may all your bids be successful!
