Our Ten-Year Anniversary Contest is now over and we talk through the solution in this “final?” Smashing the Sudoku series video here:

Congrats to the four winners: Stephen W., Mindren L., Giovanni P., and Barbitos.

We’re continuing to work on setting up a two puzzles a day subscription release model for GMPuzzles. We have a first set of testers now identified but if you would be interested in helping out as we get closer to a beta test, please let us know at ads@gmpuzzles.com. In the mean time, we’re pausing our “reposts” from the past for now while we get our 2023 plans set up, at least for April.

Our tenth Smashing the Sudoku video, finishing our original 60+1 puzzle reposting series is now live:

We’re still working on setting up an initial version for a GMPuzzles subscription/release model leveraging Discord. If you are interested in being a tester and committing to adding comments/sharing feedback, please let me us know at ads@gmpuzzles.com. We will likely have an email option to share the content to subscribers as well, but right now we are looking for testers to tell us if a Discord integration (as an early version of a more fully fledged platform) is worth committing more time to.

We’ll be posting Sudoku from our 2022 Sudoku Grand Prix Round over the next couple weeks.

Our eighth Smashing the Sudoku video for “Fleet Week” is now live:

We have two more weeks in this look back series and then we will be putting our attention to a new subscription model for daily puzzles starting in April. While we have a long-term goal of having a full digital platform to deliver puzzles, we will get started by using Discord to support a Penpa + PDF delivery of two puzzles per day. Discord should also allow for a more dynamic conversation ability between our constructors and our audience while we gather feedback on features for the future.

Look to this Sunday update space for more details on our Discord invites and on how to get an early subscription before our April launch.

Our seventh Smashing the Sudoku video (which also announces the prizes for our Ten-Year Anniversary Contest) is now live:

This coming week will be “fleet week” of sorts, with Battleships and Battleship Sudoku alternating every other day.

We’re excited to announce that Grandmaster Puzzles will be organizing the puzzles for the next World Sudoku and Puzzle Championships. This news is now confirmed yesterday following a successful vote of the general assembly of the World Puzzle Federation. The next WSPC event will be held October 15-22 in Toronto, Canada. Thomas Snyder and Serkan Yürekli will be coordinating the puzzles, with a much larger team from Canada and the US working together on all the other details.

Organizing the world championships will be a big project for us in 2023, and we are considering how “competitions” and “rankings” can be a larger theme for our new content on the website and YouTube this year. Please keep on the watch for more news and updates, and do reach out to us if you are interested in contributing to the WSPC (particularly North American authors).

In addition to this exciting news, we have our posted our sixth episode in our Smashing the Sudoku series, looking back at our launch puzzle set from 2013:

I’ve been doing some traveling so am a bit late in announcing the release of our fifth episode of Smashing the Sudoku, as we look back at the good (and evil?) sides of puzzle styles like Consecutive Sudoku and Masyu.

We’ve also now completed adding hints and solutions to the four Microsoft Puzzlehunt puzzles we’ve put here over recent Sundays. If you haven’t checked out these puzzles yet please find them alongside a few other “puzzle hunt” puzzles on our blog.

Several members of the GMPuzzles family are from Turkey, and our thoughts go out to them and to others from Turkey and Syria who may have been affected or may know those affected by the recent earthquakes on the Turkish/Syrian border.

GMPuzzles will be donating all proceeds from book sales for the next ten days to relief efforts like those of the Turkish Red Crescent; we will also match any donations that come in via PayPal over the same period (see Tip Jar in left menu). As an advance against those amounts, we’ve given $1,000 to https://ahbap.org/disasters-turkey.

Update 12 Feb 2023: Serkan has constructed a puzzle to help raise awareness and funding for those impacted by the earthquake. We’ve put together this simplified PDF to be able to play along with the puzzle.

The puzzle was also featured on Cracking the Cryptic:

with this link to play the puzzle online.

We’ve just published our fourth episode of Smashing the Sudoku as we look back at our first puzzles from ten years ago and try to bring back memories of these constructions from our first 60+1 puzzles:

In a few minutes we will also have our fourth Microsoft Puzzle Hunt bonus puzzle, which we hope you all enjoy.

After a tough January with assorted things like a power outage impacting our ability to compete on the United States Puzzle Championship, and many more events around my science work leading to a mental health break, we’re back on track for most of our 2023 projects. For Grandmaster Puzzles, we’ve now completed our recent “Best Of” series is now finished and we just released our third edition of “Smashing the Sudoku” to go along with our original 60+1 puzzle set.

Coming in the future will be some invites to puzzle contributors and top fans for our Discord channel where we are brainstorming what is next for the site (in 2023 and out to 2033 in a ten year plan), a new approach to web content, and more info on puzzle championships that GMPuzzles will be involved in.

(Copying a message below after a day where I’ve felt better than any time in the last 5 years having made a hard life decision. If I haven’t seen you in awhile or written in awhile, this is my commitment this year to share the love with my closest network, to detoxify myself and then to reconnect with my 1000 strongest connections to then see what we can do together on the problems we don’t even know to identify yet. The spark came from thinking about my move to 2014, the story of me ending my (f)unemployment from puzzles and relearning my love of science. It was a letter to Chad. I’ll not share his response unless he agrees, but I want you to know what I’m saying to my close network of people. Writing letters as with a postage stamp may not be a scalable thing to do, but I don’t care right now as it is a great way to share clear thoughts.)

Dear Chad,

There are not enough words (certainly not these 500+) that can say how much I appreciated your love last year, hearing your family connection to mental health while going through a challenging 2022 myself.

You might have seen Verily’s reduction in workforce news. Wednesday was a tough day for me after an exhausting JPM week. I drove to my college alma mater today and cleared my head and feel quite different. It’s added up to the decision in the header, I am taking a sabbatical from full-time work in 2023. I want to slow down parts of my life so that I can speed up my thinking. I want to help change the world, to coach the teams that might be able to.

My first innovative decision is to try life without a cell phone for this year, and connect back with the people I love. I may write a scientific paper after 12 months about the experience on my mental health and on others — I have lots of good measures and I am a data scientist so there could be a story there. Having gone through DBT therapy and being observant has made me recognize even just watching the homeless and mentally ill, or trying to talk to them and seeing how often I can get through — those observations from a person like me could make a difference. I think my main research goal might become tackling mental illness, but January is just about reading non-science books and trying other things.

So to keep me accountable — that this is a sabbatical and not a retirement — I commit this year, every couple months, to write you some thoughtful notes, with no rush for you to respond back (consider it a long letter sent with a postage stamp). I will be visiting different places sometime and I would love to get a set-up like a $1 and 0 equity advisor role just so I can have a badge back if I find myself in Seattle and want a place to sit and do some thinking and don’t need to send any emails to have an open door and a hotel desk. I don’t have an admin, I don’t want an admin. I want an open door like I loved having when I was at google so I could see a foreign city and get a quick snack before heading to an airport if needed. When it is a longer stay, we should certainly arrange an invited talk, a chance for lunch or other connection with you and Harlan.

I have strong connections in 10+ cities, but yours is the only one I want to start with for Seattle, because just talking about immunosequencing with some of its pioneers may revive what I felt in 2014, a time I consider one of the most stimulating in my life as I had access to all your data and to Tableau and could just play. I want my 1-2 day experiments to be things I can share anywhere, and we’ll discuss how this might be possible later. My message today was to just say I made a decision for me and am off the market but also not working anywhere deliberately. I’m going to celebrate my 43rd birthday next Thursday by being with my best friend, their partner, and child, in Boston who I haven’t seen enough since they moved away from SF during my post-hospitalization therapy.

I know we’re not genetically related, but I consider you a dear part of my family — I only use the term for closest connections and mentors/mentees in both directions. I do hope that you are managing these tough times. No rush to respond, but I look forward to a pleasant surprise in my inbox within the next 12 months. And I’ll stand by my commitment to write when I want to share a connection and fun life experience and maybe a new idea where something is connecting in a bigger picture I want to form.

With love,
Thomas
