like many of Brian's puzzles, this one requires an unusual amount of lateral thinking, the occasional break for food and sleep, and in some situations a running sotto voce commentary with questions to no one in particular. (don't worry about it, no one's watching you, take your time.)
also, the intended solution requires no force. (physics teachers please refrain from commenting.) i note this in its own paragraph because there was a bit of controversy among solvers about whether a particular method during part of the solution should be considered 'creative' or 'cheating'...and i would rather not say whether i used the method in question as i fear it may tend to incriminate me.
from the description on the Mr. Puzzle site:
There are elements in the puzzle Brian would consider as much easier than 10/10. But he’s incorporated completely new ideas in this puzzle too so that always throws a spanner in the works and makes the puzzle harder. Overall, we do think it’s a very difficult puzzle. To work it out with his intended solution we believe its definitely worthy of the 10/10 rating.
The making of Abraham’s Well puzzle has been a huge undertaking for Mr Puzzle. Brian had a concept for the major step in the puzzle way back in 2018 and began designing the puzzle around that. Perhaps the most difficult part of the design is to know when to stop adding things to the puzzle.
Abraham’s Well has many separate steps to solve with a level of complexity comparable or surpassing previous multi-step sequential discovery puzzles. Physically the puzzle is smaller like the Plugged Well. But it has so many steps it’s more like solving the Opening Bat. Not that the Aha! moments in either of those two puzzles have been repeated here. This is a totally new idea.
The puzzle can be separated into are 23 individual parts. There are another 21 parts that are glued into the body and never actually come out of the puzzle. There’s a tool for every step of this puzzle and a big part of the puzzling is to work out which of these parts are tools, and which are not. The tools are tightly packed and very well hidden.
A major characteristic of this puzzle contributing to the difficulty level is that even if you’re able to take the puzzle apart using a non-intended solution or even just by chance, you cannot reverse engineer the solution just by seeing all the pieces laid out in front of you. This is quite unlike most other puzzles that we know about.
All the parts of the puzzle, both woodworking and metalworking, are made and machined here by Brian and his team at Mr Puzzle. Making the brass parts for this puzzle is a massive undertaking. But it’s not only lathe work. He bought a new Milling Machine too! The table saw, 4 routers and the CNC were used in the making of the wooden body of the puzzle. The importance of jigs cannot be understated and the running sheet with the steps to make each puzzle is very important.

all puzzles in my collection have been kept out of sunlight, in a humidity-stable room, away from pets unless they can solve them, and in a non-smoking household.
thank you for looking, and good luck if you bid.
