📲 Play offline on your phone
Add Offline Arcade to your home screen once while you're online. After that, all 13 games open like a normal app and work with no internet: in airplane mode, on the Tube, anywhere.

🌐 First: put the arcade online (one time)
You're running the arcade from files on a computer. It already works offline here, but a phone can't open files from your laptop. To install it on a phone, the folder needs to be hosted at an https:// web address once. It's just static files, so any free static host works:
In the folder, run:
vercel --prodYou'll get a link like
https://your-arcade.vercel.appGo to
app.netlify.com/drop and drag the whole folder onto the page. You get an https link instantly.Push the folder to a GitHub repo, then go to Settings → Pages → Deploy from branch.
http:// on your Wi-Fi (e.g. http://192.168.x.x:8080) works for playing, but browsers only allow offline saving on https:// links (or localhost).1 Open the arcade on your phone
Point your phone's camera at this code and tap the link that pops up. Or send the link to your phone:
2 Add it to your home screen
- Open the link in Safari.
- Wait until the This device box on this page says Ready offline. It takes a few seconds.
- Tap the Share button . It's at the bottom of the screen on iPhone and the top on iPad.
- Scroll down and tap Add to Home Screen ⊞. If you see an Open as Web App switch, leave it on.
- Tap Add. The Arcade icon appears on your home screen.
- Open the link in Chrome.

❓ Troubleshooting
It says “no internet” when I'm offline
The arcade only saves itself once it's been opened online. Open it from the home-screen icon while connected, wait for Ready offline on this page, then try airplane mode again.
How do I get updates?
Just open the app while you're online. Any new version downloads quietly in the background and is used the next time you launch it.
My scores disappeared
Scores and high-score tables are saved on each device, separately for each browser. On iPhone, the home-screen app keeps its own scores separate from Safari.
My iPhone forgot the offline games
Safari can clear saved data for websites you haven't used in a while. Adding the arcade to your Home Screen (step 2) keeps it safe.
Does it use data or track me?
No. The games don't connect to the internet at all: no ads, no trackers, no accounts. Sounds are generated on the device, and the quiz questions are built in.
