We’ve gotten the red flags outside of the grid but still cannot make sense of them. It may be tied to that shiny yellow number in the corner, another survivor from yesterday’s expanded challenge. The rest of this space is from the new training ground we traveled to. Who knew training reasoning models with just 50 word tokens could lead to such amazing intelligence? Given our rate of progress, we’ll show off “Full Setting Automation” by tomorrow!

Nothing to worry about; some minor issues before we can show off our full self-setting technology. We’re being warned that the flagged number is causing a disturbance that puts our powerful AI at risk. Still, we have new hope that we have eliminated all weak spots in our GPU core. No more big explosions today. Given our rate of progress, we’ll show off “Full Setting Automation” by tomorrow!

The fourth level of self-setting is “High Setting Automation”. The editor relaxes as an automated, intelligent process (AI) generates grids that are then passed to a second AI the editor has set up to reject almost everything that is not an outlier, since corner cases may be the only interesting things left to search for. When needed, the editor still acts to reject unfriendly logic before publishing.

We have a few site updates for the start of July, which marks the start of our second full month in the Twelve Months of Sudoku!?! project. A playful YouTube recap of the first month of sudoku is in this video that shares the goal to see “how far we can push the limits of sudoku”:
The big news in June was starting to publish the Genuinely Approachable Sudoku (GAS) puzzle here, a series we love as a great daily game and expect you already love or will come to love in the same way. Having met our soft-launch goals, in July we are making this next update: The daily GAS will be available each day here at 12 AM PT for everyone in the world to build into their routine however they choose. This is the same time as some of our other daily games that we make for LinkedIn and my own daily routine will be to spend a little time double-checking the Queens, Zip, and Tango before solving ~1 GAS puzzle to track my thinking that morning and try to come up with one new idea, even if I just leave it on paper that day.
We don’t yet have our own book/app project with the GAS team; if you want to support clover! (Patreon), Philip Newman (Patreon), and Bill Murphy (Patreon) individually you can go to the pages linked here. One thing you can get by becoming a patron is some of the more GMPuzzles-like difficulties harder than GAS, still with impressive grid construction as you’ll have seen from the regular GAS.

The other news for July is the start of my “A Story of Self-setting Sudoku“. For a few months I’ve had an idea for a new way to share puzzles that might change the experience a bit. Some may remember the challenging mix of themes in the “Twelve Days of Sudoku” / “Ready Layer One” era (perhaps month 0 of this project?), which had a mix of puzzle types and modes and essays and conversations on mental health and a lot more. I was first pushing that creativity while in a productive, creative state and then later while in a severe hypomanic state, and without the usual team support to keep on target.
This new project aims to reach the interesting and enjoyable potential of that winter project, with more controlled construction and puzzle release. It will still be experimental, and may give off puzzle hunt or ARG vibes alongside other things, but it’s “Layer One” is just a daily puzzle with a little flavor here on the blog and is only much more if you choose to visit our Discord and watch and/or participate with the items that pop up there.
There are three things “A Story of Self-setting Sudoku” is about. First, it is a story. Each puzzle fits into some of the preceding or following puzzles, with a few sentences of text connecting some dots (no more than can fit on a puzzle PDF page). The series is launching with a theme of self-setting (while some AI may be harmed in the making of this series, it is up to you to determine if any were ever used); this may change the conversation from “How did (you/the constructor) make that?” to “Why did (you/the editor) find that important?” and other things too. It will have a daily Sudoku puzzle with difficulty and solving times behind spoiler tags. If you just want a daily Sudoku-like thing more Classic than the GAS, for now this series is my answer. Later in the year, there are other projects brewing that are not “art projects” and are meant for the mass-market that we will point you to instead if the GAS or “A Story of Self-setting Sudoku” are not what you are looking for. There are possibly Easter eggs, and Discord-specific elements (a lot of the extra story/interaction has to happen on Discord).
As always, there are lots of ways to reach me / our team, from blog comments to Discord messages to email or mail. For a little while, I am not going to be posting messages here or on Discord (except automated puzzle posts) and will leave it to mars and their AI solver to try to understand what “A Story of Self-setting Sudoku” is really about. Feel free to read that story, or try to outsmart the AI solver if you can. I’ve left some messages sealed in envelopes for when certain events happen which will be reported here or on the Discord. Enjoy the rest of July!
The third level of self-setting is “Conditional Setting Automation”. The author can now simply ask, for familiar grid patterns, for automation to generate valid Sudoku with specific characteristics. The author — now more of an editor — relaxes until there are thousands of solution paths to watch go through their steps, and looks for whatever is “interesting” to the eye. Beauty is in the eye of the editor.

The second level of self-setting is “Partial Setting Automation”. The author, who has come up with a previously interesting grid pattern, finds a new starting seed, and then uses computer assistance to add all other numbers to generate lots of valid puzzles which guide the picking of a preferred “gem” from suggested characteristics including novelty, breadth of solving path, and the kind of steps.

The first level of self-setting is “Setter Assistance”. The author, who has thought of an interesting idea, comes up with a grid pattern by hand, fills in a starting seed, and then adds the remaining numbers with some software to characterize the remaining solutions and get a unique Sudoku. AI is used for making postscript art, but not the AI within AI which is more than just assistance.

Happy Two Pi Day to those not yet aware of other events today. We thought a combination of Thermometers and Arrows would be a great way to celebrate a natural constant!
or solve online (using our beta test of Penpa-Edit tools)
Theme: Because 2 π’s Are Better Than One
Author/Opus: This is the 583rd puzzle from Thomas Snyder, aka Dr. Sudoku.
Rules: Standard Sudoku rules (insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region). Some thermometer shapes are in the grid; numbers must be strictly increasing from the round bulb to the flat end. Some arrow shapes are in the grid; the sum of the numbers along the path of each arrow must equal the number in the circled cell. Numbers can repeat within an arrow shape. The coloring is strictly to emphasize the theme.
Difficulty (highlight to view):5 stars
Time Standards (highlight to view):Grandmaster = 12:00, Master = 24:00, Expert = 48:00

This Kropki Pairs Sudoku was inspired by a variant selection and puzzle by Philip Newman from earlier today, as Thomas explored how some new themes can be added to Consecutive Pairs by allowing multiplication on the other side of a grid.
Author/Opus: This is the 582nd puzzle from Thomas Snyder, aka Dr. Sudoku.
Rules: Standard Sudoku rules (insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region). If a white circle is given between two adjacent cells, then the two numbers in those cells must differ by 1. If a black circle is given between two adjacent cells, then the two numbers must have a ratio of 2. Pairs of cells without circles can have any relationship.

or solve online (you will need to activate “letter tool” in the settings menu)
Author/Opus: This is the 581st puzzle from Thomas Snyder, aka Dr. Sudoku.
Rules: Place a letter from the phrase “SHINY GOAL” into each cell so that no letter repeats in any row, column, or bold region. If you are not finding one true calling, you might need to find two crossing copies of the mantra HOLY in the grid, each appearing in a straight line in some direction (like in a word search).
