- Alex Bezos's Monday Puzzle in The Guardian. Usually a few thematically related problems in ascending difficulty.
- Catriona Shearer's Felt-tip Geometry Problems. The problems are elegant and fun, and it's neat to see in the twitter threads the variety of ingenious approaches people take to solve these.
- Fivethirtyeight.com's weekly contest-like (posted Friday, answers due by Sunday night) Riddler, edited by Oliver Roeder, consisting of an "Express" puzzle/problem and a "Classic" that can range from hard to way out there. People (including me) sometimes blog their solutions to the Classics.
- The Puzzles category of the Futility Closet blog. Most common are 2-move-mate chess problems, but also other math and logic riddles.

Thanks for these, Hector. They are all new to me, but I will check them out! The fivethirtyeight one sounds particularly good.
Other than the NYT Mini, I don't really have any to add. Spelling Bee and Letter Boxed too, I guess, but those are both behind the NYT paywall.
Also, you should plug your own puzzles, which I found on the website you have in your profile! I haven't tried them yet, myself, but I will give them a go as well.

Thanks, Brian! Most of the puzzles on that blog site are Riddler ones; only the solutions are mine. (I have, though, authored a couple of the Riddler puzzles over the years.)
