The benefit there is that the events are hand-curated with interesting historical facts and link to articles on the topic if you want to read more. Also real photographs, not extremely obvious AI imagery. The mechanics are also nicer -- placing events one by one ramps the difficulty up rather than trying to one-shot it and correcting mistakes.
fair point, my images are not meant to be realistic anyway, I actually prefer this semi-realistic, high-contrast, rich in color style - that's why I generate them having that specific style. anyways, isn't it great that there are different takes on the concept so everyone can pick what fits them best? :)
The "earlier" and "later" labels really confused me because I think they could be interpreted either way. Also the AI art is corny. But I'm guessing this is all just AI generated
Fun game. I like the name! Consider making the card description two rows on mobile. All of them got truncated, so I had to click on them to be able to read the last word. I think you have space for the full text.
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!
guys, I added OPTIONAL google login, so you can play on many devices without losing streak & stats.
Wanna migrate current streak & stats to you google account? -> just go to the desired device and sign-in there. -> local progress will be migrated to your new account.
( 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?
Most people share their result with friends and family in text threads. It’s for fun and starts discussions, many times out of a solution being surprising or tough. The best times are when one of us can’t figure out a solution and we give each other hints.
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
Wow, just played my first game and I wild-guessed it and got it right in 1 attempt. Maybe time to go buy a lotto ticket...I honestly had no clue! Good job on the easy-to-use interface.
glad to hear you find UI easy to use -> that is my main goal. btw, were the images working? cause i just found out they were not working for a couple of hours, already fixed it :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.
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.
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
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.
Timdle's UI is a bit wonky but the NYT puzzle is very straightforward - you just drag and drop each event into the timeline. The reason it's weekly is because they likely are curating them by hand.
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.
I noticed the images are from Gemini, but what's with the rectangular blurring in the bottom-right corner? It only covers part of the logo, so I assume you weren't trying to hide it. Is there some kind of embedded identifier? I remember DALL-E images having something similar, but does Gemini actually link it to your account or something?
tbh I didn’t want to hide the gemini watermark at all, i’m just processing images (size, optimization) using CC, and for some reason it decided to blur them - and did a pretty shitty job at it, haha
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
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
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
yeah, i'll probably adjust the prompt for image generation to make them look more hand-drawn, visible brush strokes. i tried to express this in my current prompt, but gemini kinda slipped into this AI style too much xd
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.
NYT has a weekly version of this for those interested
https://www.nytimes.com/interactive/2026/04/17/upshot/flashb...
imagine waiting a week lol

Fixed! yeah, that was pretty annoying, thanks for suggestion. glad you like the game.
Looks good now!
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!
If you mean adding the years of the events to a timeline to match to, I think that's too much information.
In this case, I knew the rough dates of all but one of the events in the list; adding years in a timeline would have given the last away.
That's actually not a bad idea, will definitely consider that.
guys, I added OPTIONAL google login, so you can play on many devices without losing streak & stats.
Wanna migrate current streak & stats to you google account? -> just go to the desired device and sign-in there. -> local progress will be migrated to your new account.
This only happens on first login.
Very cool! Consider adding a wikipedia link to each card after the game is over.
thanks for suggestion, definitely gonna implement something like that soon
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
( the six green squares don't render on HN ) ... which is still a string that can be readily edited.

Very fun! My family is a big fan of the Chronology card game (https://buffalogames.com/chronology/), hopefully this helps me win next next time :)
glad you like it!

I saw images (I think?), nothing looked off!
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.
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.
not a bad idea at all, would be fun :D
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.
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
This, as well as the NYT game, is heavily inspired by https://www.timdle.com ?

yeah, that drag & dropping event into timeline one by one definitely has something to it, I was also considering this concept
it’t just about which style and mechanics people wanna do more
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.)
Nice game. I can see myself playing this daily.
How do you plan to feed the questions? Is it with AI or manual work?
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.
I noticed the images are from Gemini, but what's with the rectangular blurring in the bottom-right corner? It only covers part of the logo, so I assume you weren't trying to hide it. Is there some kind of embedded identifier? I remember DALL-E images having something similar, but does Gemini actually link it to your account or something?
tbh I didn’t want to hide the gemini watermark at all, i’m just processing images (size, optimization) using CC, and for some reason it decided to blur them - and did a pretty shitty job at it, haha
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
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
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
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
Excellent name!
thankss!
Nice work! I'd consider ditching the AI art though, it was distracting.
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
You might want to tinker with the prompt a bit to get a different style; the AI vibe is very noticeable as-is, especially at a smaller scale.
yeah, i'll probably adjust the prompt for image generation to make them look more hand-drawn, visible brush strokes. i tried to express this in my current prompt, but gemini kinda slipped into this AI style too much xd
Not everyone likes daily games. I hate them. That shouldn't stop you from making a daily game. Ignore the haters.
well said
I believe pulling art/media from Wikipedia would be cooler and less controversial. I also believe the licensing allows it.
yeah, got your point. i still find the style of my generated images pretty nice and consistent.
I'll take the other side of this argument: I like the AI art. Easy way to make it more visually engaging
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
They're AI generated, so obviously not accurate.

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.
Fun
thanks
Cool, I would play this
Hopefully EMEA isn't all of history /s
no, just a coincidence today, haha
