Artist’s note added 12/23 at 6:28PM: This image, an information network presented in artistic and mathematical form has an alternate title called “Portrait of the Artist’s Brain at Middle Age”. The network includes puzzles and possible seeds for puzzles as well as tests of new network structures to test memory, cognition, and a lot more.

This trailhead and all following work were constructed with the constraints of 1 day for the main puzzle (above) and the rest of the week to finish other content whether traditional puzzles, new types of puzzles, meta-puzzles, and so on. More details are not being shared as over 80% of that content, and at least very clear but still “unfinished” works appropriate for posting at least visually, exist within the full opus and a publication plan will be made in early 2025. Besides the puzzle and art constraints, the author followed a testing/accountability plan for connection with close contacts and medical care team that Thomas established through 2024 to be able to get back to doing great science again. “Party Report” is an example of a playful message that should work best for children and those with open eyes who dream of playing “The Game” with super complexity and the artist wanted a story of how his brain did pull in many notable social, societal, political and other themes into what was otherwise an unconstrained topical work. Importantly, it also includes a soundtrack listing for his team to see to ensure mental wellness. On the other hand, a lot of things may seem like noise. No puzzle, for instance, was forced to have the answer COVFEFE. But maybe the uninterpretability made it a curious answer to try to use a lot showing the relevance of journeys to answers, and the skills and intelligence gained along the way.

The author wanted the downturn phase (when one transitions from learning/doing a problem to having solved it and teaching) to include an unconstrained (certainly unpredictable) experience while returning to his more normal medium of fragile humanity. “Penny for your Thoughts” is a separate opus, but should not be presented except as a margin note of the “Ready Layer One”. Many other puzzles including the Motivational Posters, with progressive simplicity and hints and eventually full solutions accessible at the start are meant to stop the rush of people bringing up mental illness to allow the rest to enjoy some phenomenal puzzles, sharing a love with their friend and vice-versa, while also still highlighting the importance of acknowledging mental illness in the creation of these works too (just not at the times people expected).

[Note: The remaining two Microsoft Puzzle Hunt puzzles will be released on upcoming future Sundays (starting Jan 29) since these are involved puzzles to solve and harder than our usual weekday content.]

[More comments about the site below; for now, here is the first of four puzzles that I wrote for last year’s Microsoft Puzzle Hunt. Our “Binary Earth” round had paired puzzles that would look similar with a “large thing” and a set of “small things” to look at. This is the easiest puzzle of the set, entitled EXPLORER. Just as at the Microsoft Puzzle Hunt, it is presented solely as a PDF with no specific instructions. I will add hints each day as I also release the other 3 puzzles I wrote for that Hunt this week.]

[Note: I had a very busy weekend, including some mental health care which took me offline completely for 4 days, so have not reformatted the puzzles for this week yet or made the second “Smashing the Sudoku” video either. Amazingly, those busy weekends did not include full completion of the USPC or any participation in the MIT Mystery Hunt so things must be pretty serious for me right now. Reflecting on some of the comments from my post last Thursday, I do not want this site to go completely dark during my sabbatical year, but it may be less predictable when content gets added until we have our other puzzlemasters able to do web tasks more. That said, I also don’t think we need to release more free web puzzles without a new platform that can really grow our audience. Our planning for 2023+ has kicked off in a new GMPuzzles Discord channel that we will open up to authors/top fans soon.]

Dear friends,

This weekend is the MIT Mystery Hunt and Grandmaster Puzzles is very happy to be a sponsor of this puzzle event in 2020.

If you are new to this site, there are lots of different fun genres of logic puzzles to explore and you can follow some of the links to the left to find these genres including our easiest puzzles to get started. The Intro to GMPuzzles and Logic Puzzles 101 books are some great titles to try as well.

As part of the pre-Hunt activities for the team I compete with, I created the attached puzzle set in the style of a Mystery Hunt puzzle. Like most puzzlehunt puzzles, it is missing some of the instructions you may want to have but I think you may still be able to figure it out. It has a final answer which is a word/phrase. We will post some hints and/or the answer in the coming weeks.

See this PDF for the full week of Snake Pit puzzles from Carl Worth.

If you noticed anything unusual about the puzzles this week, it probably wasn’t an accident. Carl has hidden an additional puzzle within the six Snake Pits. Find and solve that puzzle to determine some counsel he’d like to share with you, perhaps something to use when approaching puzzles like these.

The final answer to the hidden puzzle consists of eight characters (specifically four CAPITAL letters followed by four numbers). Nothing outside of the six Snake Pits has any bearing on the hidden puzzle, including this text.
