AI - I created a custom prompt to generate those event, so that the difficulty is just right, not that easy, but not that hard also. Took some iterations to polish it, now it kinda feels just right.
Same with the image generation - custom prompt so they have this specific style.
( the six green squares don't render on HN ) ... which is still a string that can be readily edited.
It's more resources your end to save game results for a specific play and generate a unique checksummed hash key for a third party URL lookup, sure, so I guess the question is how important is it for players to reliably share their results in a manner that is hard than a simple edit to 'cheat' on?
very good question. My take is that once the result becomes this easy to manipulate, like simply editing the result string, it kinda defeats the purpose of doing so :D . If anyone can do it then it kinda loses meaning and there’s not much point to doing so in the first place :D
yeah, you're not the first mentioning this. I was just so proud of that name + animation combo I had to make sure it's visible all the time xdd but yeah, will consider dropping it / adjusting intensity
A fun variation would be to create the cards from social media posts or articles, stripped of dates. It's astonishing how little context the geoguessers need, I expect the same for chronoguessers.
i was HEAVILY inspired by wordle, wanted to create a daily game with similar mechanics. This concept came to my mind, but yeah, after it came to my mind i checked if something like that already exists and bumped into thing you just posted. UX seemed kinda complicated to my, my idea was to make it as simple as possible, drag & drop, so people can play it while commuting daily (tram, metro, bus), and will take like 2 minutes of their time.
Neat! I think with more events (~9) and obscure ones it would be more fun. I also think it would be fun to make it possible to play previous days. Bookmarked.
yeah, i was considering it, but to be honest the only reason i decided to go with 6 event is to make it playable on mobile device with images big enough to see soemthing :D
Very fun. Would you consider putting years on the timeline to match the events up to? I think from an education perspective it would be a great feature! Nice Work!
Nice, I enjoyed it. Fyi I think you should edit the title to be "Show HN: <title>". This will mean it will be on the /show (https://news.ycombinator.com/show) page.
got you man, had this problem with wordle too, but there's something nice about being only able to play it once a day. daily ritual while drinking your morning coffee and then sharing it with ur family/friend of course :D :D
I love those :D took me some time to come up with the custom prompt to make those images have that specific art style, but yeah, I understand that not everyone like s AI art
How accurate are these pictures? I feel like I see ideas like this on HN pretty often and the art always gets things wrong. Like all the same clean armor during the first crusade seems doubtful and two swords on horseback just seems wacky. Two swords like that is dumb normally but also how do you control the horse lmao
Although we live in a post-truth age and AI generated photos are used in historical and academic contexts now so it doesn't really matter much anymore. The past is just a vibe.
Agree. My goal wasn’t 100% accuracy so much as capturing the overall feel of the event, more like a collage that includes key people, features and atmosphere of that period.
Very cool! Consider adding a wikipedia link to each card after the game is over.
Nice game. I can see myself playing this daily.
How do you plan to feed the questions? Is it with AI or manual work?

Noodling kind of question, Share results / copy to Clipboard both seem to put the same string in the local clipboard:
Hisorty #9 1/3 https://hisorty.app

cool game, maybe consider removing the eternally looping animation in the header, it's pretty visually distracting
Or loop once/twice... it's a fun effect, but when endless I agree that it's distracting

not a bad idea at all, would be fun :D
NYT has a weekly version of this for those interested
https://www.nytimes.com/interactive/2026/04/17/upshot/flashb...
imagine waiting a weeeek... jk :D
This, as well as the NYT game, is heavily inspired by https://www.timdle.com ?

Should have 5+ puzzles to do on the first day, so people can play enough to remember it. (They can be the same 5 static puzzles.)

That's actually not a bad idea, will definitely consider that.
Maybe I missed it but if I don't solve in time, it didn't show me the correct answers.
There is no timer implemented as far as i know :D , it shouldn't be the case :D
Nice, I enjoyed it. Fyi I think you should edit the title to be "Show HN: <title>". This will mean it will be on the /show (https://news.ycombinator.com/show) page.
Thankss! Yeah, good tip.
awesome! but the one per day thing kills it for me.. I want to play like 10 in a row and then forget about it for a few months.
got you man, had this problem with wordle too, but there's something nice about being only able to play it once a day. daily ritual while drinking your morning coffee and then sharing it with ur family/friend of course :D :D
Excellent name!
thankss!
Nice work! I'd consider ditching the AI art though, it was distracting.
I believe pulling art/media from Wikipedia would be cooler and less controversial. I also believe the licensing allows it.
I love those :D took me some time to come up with the custom prompt to make those images have that specific art style, but yeah, I understand that not everyone like s AI art
Not everyone likes daily games. I hate them. That shouldn't stop you from making a daily game. Ignore the haters.
well said
I'll take the other side of this argument: I like the AI art. Easy way to make it more visually engaging

They're AI generated, so obviously not accurate.

Fun
thanks
I like it! A quality old school learning game, like we had in the 90s
I’m also a huge history guy so anything that helps people understand history better is great
Was the goal just to make this for yourself and see how it goes?
Yeah basically, I'm very curious to see if people will actually find this wordle-like history game interesting and if they'll stick to it.
But i also often find myself just staring at some of those images and eventually finding more about some of those on the internet.
