Have a look in here for the rules and some tips.

It will give you a unique link that you can then share to anyone!
Check 'SG' to put a full SteamGifts URL.
Once solved, your secret message (or giveaway link) will be displayed :)
All puzzles are guaranteed to have a unique solution and won't require any guessing.
I made it in Javascript using the p5.js (Processing) library.
I was able to reuse parts of the previous generator I had, but had to make a solver for it (since in 2020 I was manually solving and rebuilding puzzles until getting a unique solution) and build the playable interface. Lots of fun!
The trickiest portion was the encryption of the puzzle ids to hide the secret messages, took me two full days with ChatGPT as a backseat driver...
If you're curious about what a sleep-deprived dev can come up with, have a look at the code on GitHub!
I want to make this tool as convenient as possible so that anyone may create and solve nonograms.
Let me know how I can improve it!

Thanks!
It was quite a hassle to code but the logic itself isn't as complex as we'd think.
I made a long binary sequence using all the info I need, and then converted it to characters for the id, then I read it by reversing the steps.
It all starts from the fact that SG giveaway ids have 62 possible values per character, so I made my IDs use all of them, plus - and _ to get 64 possible values per ID character.
The ID is built that way:
[version][gap][padding][numRows][numCols][seed][encodedMessage]
version takes 6 bits (so 64 values) that I use to mark the version of the puzzle, so that if I change the logic of ID creation in the future, past puzzles can still work.
numRows and numCols each take 5 bits (32 values) and will determine the size of the puzzle
seed takes 31 bits and is a large number generated from the secret message (essentially looks random) that will be used to get random values in a predictable way (so that anytime we generate values with that seed, we get the same randomness). It is used to regenerate the whole puzzle
encodedMessage takes the rest of the space, with 6 bits per character for SG gift ids, or 8 bits otherwise to get more characters (accents, symbols, spaces and whatnot).
gap takes 3 bits (8 values) and tells how many characters are missing to make a multiple of 6 (to fully encode the id in alphanumeric characters), and padding is empty characters to fill that gap.
And finally to make it look even more random, I shuffle the bits around (again, in a deterministic way) and I convert the binary sequence to my extended alphanumeric numbers by reading them 6 bits at a time.
And yup as you mentioned, the solved grid of the puzzle is the only thing that can allow us to read the encrypted message, so solving we must! ^^

Yoooo, finally not having to do the picross puzzles in paint :D
Thank you for the effort, and for giving some more love to these, i much prefer them to jigsaws (which i suck at, and despise :D)

So true, I do look back at the first version with some fondness, but gosh the solving was awful xD
No amount of pretty colors and gridlines could make it feel better to solve haha
Plus the QR codes have built-in redundancy, which means that if we do a little mistake here and there, we can still get the code in the end.
Not on my watch :P Now only the perfect solution works ^^

solved for fun because nonograms are awesome :)
Also Murder by Numbers is a great game.

I played many of them, but the throne belongs to Paint it back. It's by far the best picross game I've ever layed my hands on. I think I've played it through for three times or more by now, it's just that good (and for lack of competition).

wishlisted, thanks :)
I really wish I knew about these games 24 hours ago when the Winter sale was still on lol. I didn't check the Murder by Numbers page and didn't know there was a Nonogram bundle that I would've bought if it was on sale.

At first I was confused with the solid lines thinking they were an additional part to the nonogram... but then I realized it's just a visual indicator for every 5x5 section, nothing else. Ugh.
If I had one suggestion it would be for a toggle to disable that, as it actually confuses me more than it helps.

Yeah it's a standard of nonogram puzzles, to help visualize more the bigger numbers but I can see how it may become confusing
I will definitely try to add some customization options in the future to provide different solving experiences, thanks for the feedback! <3

This is awesome! Definitely bookmarking to use for future giveaways. You can never have too many nonograms! :D

Bump, love nonograms, expecting Murder by Numbers to appear in giveaways at some point :) (should really go back and finish it)

Bump, if someone loves nonograms there is Paint it back too !

Played like 40 hours of Mario's Picross early 2024 and even taught my co-workers about it. Glad to get back to them, been a while. Overall everything feels good (Defintley more conveneinet than the old ms paint fill tool method you did a long time ago).
Only suggestion I'd give is a way to save your progress (kind of like in Jigidi), so you can get back to the puzzle later on. maybe local storage can be used to store the users current game state.

That is a great suggestion and I think I know just the way to make that work :)
I don't have a server per se, but I could export the puzzle as a link with an additional info containing the solving progress, so that the link may be used in the future to continue from wherever we were.
I'll work on that!

I like how this works, but have 1 suggestion, normally in nonograms you have squares of 5 by 5, then a thick line and then 5 by 5 again, but this one also has squares that are smaller, which in small puzzles isn't a big deal but for bigger puzzles it would be, I would suggest make them all 5 by 5 and then just add a few 0 at the end to cut that part off, that way it's easier to calculate bigger numbers.
Ps. I love doing nonograms so great job!

That's a good point, I remember wondering about that in the past, whether to keep them at multiple of 5s or not.
Personally I always found it easier to not see the empty columns rather than having to mentally remove them while solving, but that's just a preference.
I will be adding some customization options in the future so that's part of the things I will address.
Thanks for the feedback! :)

Thanks for the puzzle! I solved it in reverse, with the little dots being according to the numbers (seemed easier to follow for me), but it doesn't give a win screen when solved (had to swap them).

Thanks for that, i don't know why, but i tried the right way and it just didn't look right to me :D

The 10x10 puzzle (Week 4) opens a 12x12 puzzle.

This is much harder than Pixross, but I managed! Thanks a lot, unexpected amount of fun

RosimInc's 2025 Nonogram Café
Announcement - 2025 Edition Begins!
Hello everyone!
First of all Happy New Year to everyone, I wish you all a lovely 2025 <3
Back in 2020, I made the first version of the Nonogram Café, it was a lot of fun but it was quite tedious to create and play the puzzles.
A week ago I started looking at different alternatives online, and finally gave up, and made my own creator and player instead.
So I officially present to you my fully online, fully interactive nonogram player! ^^
Which comes with a nonogram creator, naturally. Look below for the link to it!
I will post a new nonogram weekly, leading to a giveaway each. Giveaways will end one week after the next for fun all year round!
Now you get to play; let's get cracking!™ ;)
Weekly Puzzles
The links below contain everything you need to access the giveaways I made.
