This is nice!

Readers may also enjoy Simon Tatham's puzzle collection, available for mobile as well: https://www.chiark.greenend.org.uk/~sgtatham/puzzles/

(My favorite currently is Dominosa. Playing the Hard mode is teaching me new patterns.)

Strong +1 to Simon Tatham's puzzle collection. One note: the main iOS app is a little wonky in places. I've been using Kyle Swarmer's "Puzzles Reloaded" app, which is a little nicer in places.
The MacOS build on the page is quite old, and doesn't reflect recent fixes/enhancements. If you want to build it from source for MacOS the included instructions won't work because Simon's 'halibut' documentation tool will be missing.

So you need to:

1) Build Halibut from source:

   git clone https://git.tartarus.org/simon/halibut.git
   cd halibut
   cmake -B build -DCMAKE_BUILD_TYPE=Release
   cmake --build build -j
   # binary lands at: halibut/build/halibut
2) Build the puzzles app, pointing CMake at that halibut binary. Do this in a fresh build dir (don't reuse a stale top-level CMakeCache.txt that already recorded HALIBUT-NOTFOUND):

   cd /path/to/puzzles
   cmake -B build-osx -DCMAKE_BUILD_TYPE=Release \
       -DHALIBUT=/full/path/to/halibut/build/halibut
   cmake --build build-osx -j
3) Now you have build-osx/Puzzles.app and can (optionally) build the dmg:

   cd build-osx && cpack

I install Simon's collection on every device of mine, as well as PySol.

(I'm stuck on Guess aka Mastermind right now, and damn good at it if I say so myself! Also Solo aka Sudoku on 6 sub-blocks, with X+Jigsaw+Killer & No symmetry+Unreasonable difficulty.)

Yeah, this collection is _awesome_. I'm currently enjoying the Towers (just do it on 5x5 simple, and find it quite relaxing!).
This one is so good. Original puzzles, works fine on mobile. Very future proof.

My favorite is pearl.

I feel like I shouldn't need to say this, but Simon is also the Author of the awesome PuTTY. Until fairly recently, a vital tool of anyone doing remote management from Windows.
(Over a decade ago now?) I created https://kardland.com with a couple of solitaire games. No ads or other bullshit.

I had intended to add more solitaire games but moved on to other projects. At the time it was an excuse for me to learn Javascript.

How do you plan to keep it free from ads? I see it has accounts, if it was completely client side, it could have been forever free.
Please copy the LinkedIn Games !

I feel like the Nonogram is AI generated? There’s no way a human would set a perfectly symmetrical “diamond” as a medium difficulty puzzle. Worse yet, the hard difficulty is just “big diamond”, the same thing on a slightly larger grid.
I mean the front page is full of LLM smells, so presumably the games are made that way too.

And that's fair; this whole thing could be one-shot with any of the leading models.

The nonograms get more difficult as you do them. I actually made the diamond one myself, haha! Not too challenging really. I'm not good with making pixel art, but I probably made half of them by hand and I used Fable 5 to make the rest. I didn't actually find Opus or GPT-5.5 very good at making them. Or if they had an idea that was good, I had to fix it myself. Fable 5 was much better and 80% of its ideas looked decent.
I was also very confused. I started a medium puzzle and was immediately thrown off by the borders. Thicker borders are usually every 5 cells, but here it looks like they've been added just to equally divide the puzzle into 3 chunks.

Missing small details like these makes it fall into the uncanny valley. It looks like a typical puzzle on the surface but when you try to solve it all the mistakes stick out.

By the way, if you are interested in nonograms specifically, there is a great website nonograms.org that has tens of thousands nonograms (both B&W and color) and no ads.
Oh yeah, I think I've seen it before. I got some inspiration for some of the nonograms that I made from some different sites. Not all of the sites that I've seen have had a great UI, especially on mobile, which is why I wanted to add nonograms to this site specifically.
Well i like the theory but all of your nonograms are symmetrical or diamonds. Not exactly much of a puzzle

And what sort of monster doesn't have nonogram sizes in multiples of 5?

I'm 99% sure this was an invalid Sudoku puzzle.

Just before putting the 2 in here (above the pencil 6), I put in 6 and it said Mistake, so I erased it and put 2. But... why wouldn't 6 be valid there?

EDIT: As per replies, "X" Sudoku is variant with a different rule. While I saw the diagonals "highlighted" in another color, I didn't know that rule. Perhaps it could be added to the page for those unfamiliar with this non-standard Sudoku variant?

Nice! A few word games would be cool: scrabble, boggle, etc.
Nice! I wanted to share a link to Ripple Effect Hard with my time (23:47), but it seems the URL only captures attempts, so there's no real way to link to the puzzle itself.

Might be useful to

- add a wordle-style 'SHARE' button, and/or

- make the canonical URL that of the puzzle (and only the attempt on completing/abandoning it)

The homepage is a little overwhelming, other than that cool site
I took a quick look at the source:

      // Fire view events (e.g. unlock_prompt_viewed) for any monetization prompt
      // present in the freshly loaded page. data-analytics-view-events is a JSON
      // array so one rendered prompt can report several events at once.
What's a monetization prompt?
Looks great. FYI, Claude has idunno, maybe 20-30 different strongly themed websites it knows how to make, and this newspaper aesthetic is one of them, and all the sites it does this way look exactly the same.

It's a good aesthetic for your site, and I thought it was a good one for one of my sites. But eventually I redesigned my site significantly when I saw that it's gonna be common among vibed-up website designs and they look exactly the same.

And here we are again. A nice idea, ai generated, for grabbing email addresses... Not even trying to give it a human touch. Is this the new spam? Hundreds of sites and web apps forcing you to sign up with a temp email address for no good reason?

The "Hard" big diamond nonogram was not hard at all. Are you vibe-coding these?
After starting a nonogram level, it seems you can't go back to it because you're just prompted to sign up or log in. As mentioned already they're also shitty puzzles.
For those who like these types of puzzles, i made a benchmark called pencil puzzle bench

Testing AI model's ability to solve puzzles like these. https://ppbench.com/

Can play the puzzles and compare your timing and accuracy to many AI models on the leaderboards

Only after you create an account? Oh my lord

Not really sure if you can call Nonogram a puzzle, when you give the answer right in the title.
Now I just need an ad-free save the doggo from the bees site. =)
