I'm a semi-retired geologist and planning consultant with too many hobbies, including writing stories for Literotica. My interests tend to wander from obsession to obsession.
Is there interest in more advanced #Sudoku? This one should challenge most people. There's no sense in timing this puzzle, graded at 7.2 on SudokuWiki's scale to 10. I'll add information in the alt text.

I haven't replied with a puzzle for a while. I've been working on my ability to produce harder puzzles.
This isn't a hard puzzle. It should be slightly more difficult than R431. It started quickly then took some time to clean up.

I did it in a little under fifteen minutes.

I've taken to putting the "Hard" puzzles through a solver before I spend time on them. The solver at sudoduwiki.org graded it as 8.3 on a scale to 10 and used techniques that are out of my reach right now.

The solver at sudokuwiki.org rated it as "tough." Their solver used a method I'm not familiar with.
I couldn't replicate my solution, so no doubt I made a lucky mistake.

I solved in 13:19. I wonder if I made a fortuitous mistake somewhere that made it work.

That's a difficult puzzle, and without resorting to extreme technique.

Couldn't finish it without guesswork. SudokuWiki graded it as very hard.

15:04 for me. The cats left me alone.

Here's one. It took me 26:25, but it shouldn't be that hard. I took twenty minutes doing not much, and solved it in six.

Here's another one for late-night puzzling. As before, details in the alt text.

That was a change of pace. Solved in 10:22. I think it qualified as "Hard" because the solution needed one "expert" method.

That's not a bad idea. If you regularly solve puzzles from one source then the level usually constrains what you need to do to solve a puzzle. If you aren't familiar with the source, then you're left fishing for the methods you need to use.

Try this one in your spare time. It's one I generated. Some details in the alt text.

I tried twice and failed both times, then fed it through the solver at SudokuWiki.org. Solving the puzzle deductively requires a couple pretty advanced methods.
