This video will talk about our early history with GAS team, where we reached 50 published posts on Saturday, a great milestone for us. On the 51st puzzle (shown) something much different happened when I decided to start solving. What is it, and how do I express / unlock creativity at different times?

To hate a thing, you have to love a thing. To hate a thing, you have to love a thing. That sounds like yesterday’s theme. This video is not about repetitive computer-generated slop, but it is about repetition. Rather accidental or purposeful, there is sometimes replication of puzzles when authoring or editing. Listen to a fun story that makes us ask how certain things happen and then even forces to ask, when we are choosing a grid like a 17-given one that must be repetition if there is still a way to represent it that is something new and not just déjà vu.
We’ll also reveal the first 2 minutes of the most important Snyder Sudoku Method of construction that we don’t think anyone has done.

To hate a thing, you have to love a thing. Keep this in mind as you watch this raw video that may venture into delicate spaces but gets at what is important not just about puzzles, but about puzzle publishing, and there is a lot of scar tissue from long before the AI-hype cycle. Based on actions during the video, we suspect at least 98.4375% of slop may eventually be harmed by this video.

Computers construct Sudoku by subtracting randomly from a known solution. Humans construct by adding givens, like in a house of cards, and hoping the last few don’t topple the foundation. What if you overbuilt a solid foundation and then let a computer subtract randomly from a good puzzle to get a Sudoku?

Special author’s note: This puzzle was highly inspired by a design from Thomas Snyder even if so refactored, reworked, or otherwise changed he may not know which thing. But he probably does. You will always inspire our creations.
*Special editorial note: We had significant internal debate about whether to publish this creative Dr. Sudoku puzzle with the controversial or potentially political subtitle “Major Newspaper Edition”, as it is not clear there are (m)any major newspapers anymore, certainly compared to propaganda machines, AI / attention-grabbing platforms, and companies pivoting to all the games fit to print instead of journalism.
