A new browser game asks one question, over and over, against a running clock: is this a real photo or AI-generated? The quiz hit the front page of Hacker News with 178 points, which tells you something about how badly people want to know if their instincts still work. According to Hacker News, the whole thing runs in 60 seconds with up to 10 seconds per image, and there’s no pause button.
I played it. It’s humbling. Here’s what the game does and why it matters more than a quick distraction.
1. The format is brutally simple
You get an image. You pick “Real photo” or “AI-generated.” The next image appears right away. You can click the buttons or hit 1 and 2 on your keyboard. As detailed in Hacker News, the clock keeps running no matter what you do, so hesitation costs you.
There’s no tutorial, no explanation of what to look for, and no hints. Just your gut versus a generator. That’s the point.
2. The scoring punishes guessing
The game doesn’t let you spam answers and hope. Here’s how points work:
- Correct answer: +100 points
- Wrong answer: -100 points
- Timeout: 0 points
- 3 correct in a row: +150 per answer
- 5 in a row: +200 per answer
- 10 or more: +300 per answer
A wrong answer or a timeout resets your streak. So random clicking nets you roughly zero, and the only way to a high score is a genuine string of correct calls. Smart design. It separates people who can actually tell the difference from people who got lucky.
3. It shows you the answers afterward
When time’s up, the game reveals every image you saw and what it actually was. This is the part that stings. You’ll see the “obviously fake” photo that was real, and the “clearly real” one a model spat out. There’s a share button for your score and a reset option that clears your image history so you don’t get repeats on the next round.
On mobile, there’s an “Enlarge” button so you can inspect an image without accidentally tapping an answer. Small touch, but it shows someone thought about how people actually play.
4. Why this matters beyond the game
Honestly, the game itself isn’t the story. The story is that most people can’t do this anymore, and they don’t know it.
Two years ago you could spot AI images by counting fingers or looking at mangled text on a sign. Those tells are mostly gone. Current image models handle hands, reflections, lighting, and skin texture well enough that a 10-second glance won’t save you. And 10 seconds is generous. Most people scroll past an image in under two.
That has real consequences:
- Fake product photos in ads and marketplaces
- Fabricated news images during breaking events
- Synthetic “customer” testimonials and profile pictures
- Manipulated evidence in disputes and scams
If your detection strategy is “I’ll know it when I see it,” this game will probably show you that you won’t.
5. What it doesn’t tell you
A few caveats. The source page doesn’t say who built the game, which models generated the AI images, or where the real photos came from. So there’s no way to know if the image set is representative or cherry-picked to be hard. It also needs JavaScript enabled to run, which the page states plainly.
There’s no pricing because there’s nothing to buy. It’s free, it’s in the browser, and it takes one minute. That’s also why it spread so fast on Hacker News.
What comes next
Games like this are a cheap way to make a point that studies have been making for a while: human detection of AI images is drifting toward coin-flip territory. The practical takeaway isn’t to train your eyes harder. It’s to stop trusting your eyes as the last line of defense and start looking at provenance, source, and context instead.
Worth a minute of your day. Just don’t expect to feel good about your score.
