Brass Monkey Sixential Discovery (BMSD) Production Prototype

For more background on BMSD see the announcement page on our website.

The goal of this SD puzzle is to find the Bananas and feed them to the Monkey.

This is one of three production prototypes we are selling.  We went through many prototypes, both 3D printed and metal, and at the end of the process we've ended up with four production prototypes which, from a puzzling perspective, are identical to the production versions we will be selling early in 2024.  These were all used for our final review and some play testing (thanks to our testers!) We are selling three and retaining one.  The three auctions have slightly differing end times to help those who don't live close to the prime meridian.

The start price for these auctions is 245 GBP. This is our intended retail price for BMSD.

If you bid on this auction you'll get three things :

1. You'll be one of the first to own a copy of BMSD, six weeks before it becomes available to the (hopefully) masses.

2. There were some very minor tweaks made after play testing, you'll receive the updated parts AND the original parts in a sealed envelope to be opened after solving. Bonus puzzle : can you figure out why we made the final tweaks we did?

3. You'll definitely get thanks from us and the warm fuzzy feeling that you have helped us recoup early some of the investment we have already made in BMSD. Also monkeys love warm fuzzy feelings…..fact!

Cheers and Happy Puzzling
