I’d like to ask the good people of this community that, if you do know the solution or figure it out, that you not share the answer here. Feel free to announce your success, but there’s something to be said for discovering the answer completely unaided, even if it takes years.
It’s embarrassingly obvious once you see it though.
I think I figured it out, but it’s so easy that I don’t think that could possibly be it. But it is, apparently.

I figured it out took about 10 minutes, thought i was onto it immediately until I had 8 at the end haha
I love puzzles like this—the rule always seems obvious after you see it. It’s satisfying when something that sits in the back of your mind for years finally clicks.

Ah, typo is short for typographical error. I’v never realized that before.
Those pesky lead pieces all look the same eh!
Ever play the game Myst? As a kid that’s exactly how it was. Days of banging my head and then a rush of finally figuring something out. Really miss that
I recommend Outer Wilds then.
Go in as blind as possible. They recommend a controller over mouse and keyboard and they mean it. The DLC is just as good as the base game, but I’d tackle it after doing the main objective.
Outer Wilds or Outer Worlds because I’ve heard good things about both but know nothing about either.
I have played Chants of Zenaar some which also hits the feeling.
Outer wilds.
Outer Worlds is just a fairly mediocre sci-fi RPG (IMHO).
Outer Wilds.
I think The Outer Worlds was just an RPG.
Wilds is a mystery game of aha moments.
Take a look on tunic, but it comes with some combat action, which may not be what you are looking for.
I’ve looked at Tunic before but it always looked more like Zelda to me. I dunno why but I’ve always bounced off Zelda.
I don’t like Zelda games myself but loved tunic. The puzzles are completely different than Zelda, much more interesting. The other commenter mentioned you can tone the combat down. Maybe worth a try if it is on sale.
You can turn that down and I highly recommend doing so.
I found the combat to be quite obnoxious.
I was more of a Return to Zork kid. I’d work my way up to each character, and then kill that character to see their death scene. Then I’d start over and work my way to the next. I got all the way to the vulture at the cave, and stopped playing because I was told there were no more people to murder after that.
I always got eaten by the grue sadly.
Loved that game and every game in that series. Part of the fun was being dropped into this world with no clues and just having to feel your way around.
I admit that I surrendered after a while and got a walkthrough, which was followed by several hours of, “Oh for fucks sake I could have figured that out!”
Every once in a while I definitely needed the walkthrough too. I hear blue price hits the same feeling. My wife and I just need to find time to dive into it together
Did you ever read the tie-in novels?
I have, I picked up the Myst Reader which collects all three from a used book sale a while back. I remember them being a fun read. Nothing mind blowing but a fun jaunt through more Myst
For everyone saying it’s the difference between the two numbers, it’s not it. Because the last one should be 8 to follow the rule
Oh shit, I thought it was OP just being a dummy. Turns out I’m the dummy
Don’t search for creator of the puzzle, you will be instantly spoilered. At least some search engines return pictures with spoilers.
Figured it out. Weirdly, knowing you solved it made me confident I could too, and I don’t even know you 🤔

I focused on the anomaly ignoring the rest, tried to see what possible rules could lead to it, then went back to see which rule also applied to the “non-anomalous” numbers.
This is exactly how George Bernard Dantzig proved two previously unproven statistical theorems, when he thought they were homework assignments.
Once I saw a video about Mario Kart speedrunning history and there was a record on Rainbow Road that lasted for years. Than someone broke it but just told the community without showing how it was done. In a couple of days someone else figured it out and did it too. Sometimes we just need to know it is possible
Amazing story 💫
Thank you
Free clue: It’s not 15. That solution doesn’t work for the bottom numbers, and it’s very clearly stated that the 7 is not a typo.
Edit: What makes this puzzle so good is that it tempts you with an “obvious” solution that works with all but the last set, but there’s an equally obvious solution that does fit every set, if you can shake yourself free of the fist one.
Thanks but I’ll ignore the last set and win

I wish I saw this first. I’m very prone to off-by-one errors.
I opened the comments thinking that I solved it, then some comments with broken spoiler tags essentially spoiled the actual answer for me, despite my best efforts to ignore them.
With these types of puzzles, I normally start looking for solutions that don’t just involve the obvious operations. Had I seen your comment first, I would’ve continued playing with the first thing I noticed (and later abandoned for the wrong solution) and I think I would’ve got there by myself eventually.
Either others need to be more mindful of their spoiler tags, or I need to stop using Sync for Lemmy. It’s probably the latter; I’ve seen such weird formatting that only makes sense if I assume Sync’s Markdown renderer is broken.
Non-bastardized version:

Oh that’s easier to read in me eyes
Hah, took me nearly a minute.
Tap for spoiler
Add the digits on both sides.
? = 12
But I only got it so quickly because I enjoyed a similar puzzle once.

…continue the series.
Did I get it?

Keep going until you reach a 4!
Yes, that’s the solution
312211
13112221
1113213211
31131211131221Wonder if/when a 4 would ever show up… and what the formula for that would look like
Think about it.
To get a 4, you need either 1111, which can’t happen because thats just 21, or you have 211112, which would again just be 31.
Seems you can’t have a series that ends in anything but 1, if it starts from 1?

13211321322112
1113122113121113222112I wonder if this type of series would eventually become repeating… or is it irrational?
Still curious what the mathematical proof would look like. Not that I’d be able to understand it regardless, but curious nonetheless
Your mother’s a 4.
And your father smelt of elderberries! Harumphh
Yeah. Probably.
You realize a 4 never will happen, right?
Not with that attitude, it won’t
Edit: I found the nerdy stuff I was curious about
Edit edit: and the real good stuff

Please explain more
Is this an honest question for information or a sarcastic slap on the wrist because my puzzle is basically a hint for OPs?
No I’m dumb but eventually figured it out after reading literally every comment in the thread. This one genuinely made me feel stupid.
Thanks for the hint. I kept on overthinking it.

21 minus 13 is unfortunately not 7… Unless I’ve misunderstood what you mean?
Wow, I just woke up and saved this to have a nice puzzle to work on for a while but I figured it out in like a minute… Kinda disappointed that happened to be honest.
Same thing happened to me lol. I was thinking about primes, how numbers might add up, multiply, etc, and then I noticed the actual pattern. Womp womp lol.

I figured it out in about 3 minutes. I think I’m autistic or something
Took me a bit more and I’m not autistic. But: see below.
Hint that helped me
Reading op claiming he figured it by just looking at it and not making complicated calculations on a piece of paper probably helped a lot.
Same… My brain was hungry for a puzzle to dig into and now its already over. Big sad.
Took me 30 seconds. Autistic as f.
