Potato Sudoku
Classic nine-by-nine sudoku, and nothing else. It runs in the browser, keeps working once the signal drops, and never shows an ad or asks for an email.

Built for the part of the trip with no internet
Most puzzle apps assume a connection and pay for themselves with ads. This one does neither, which is exactly what you want at 11,000 metres.
Works with no signal
Once the page has loaded it keeps going — flight mode, a tunnel, or a train through the middle of nowhere.
No ads, ever
No banners, no video between puzzles, nothing that has to phone home before it will load.
Completely free
No paid tier, no coins, no puzzle packs to unlock. The whole thing is just there.
No account
No sign-up, no email, no profile. Open it and play.
The dead time on every trip
- Long-haul flights, once the laptop battery is gone
- Trains and buses where the mobile signal comes and goes
- Airport gates, delayed boarding and layovers
- Keeping a restless kid busy without handing over an ad-filled app
- Winding down in a hotel room with bad wifi
