Why the listing is not enough
Almost every puzzle game on the App Store can be opened without a network. That is a much weaker promise than it sounds, and it is the one most listings are quietly making. The question that matters on a flight, on a subway, or in a basement is different: can you still finish a level, and the one after it?
The gap exists because the parts of a modern mobile game that need a network are rarely the parts you think of as “the game”. Levels arrive as downloads. Lives regenerate against a server clock. Rewarded ads are the only way to refill something. None of that appears in a feature list, and none of it is visible until the network is gone.
The airplane-mode test
Do this once, on the ground, before you need the game to work. It takes about ten minutes and it is conclusive.
- Install on Wi-Fi and open the game once. Let any first-run download finish completely. Many games fetch a large chunk of content the first time they launch; if you skip this step you will be testing the wrong thing.
- Play two or three levels normally, still online. This gets you past the tutorial and any first-session setup, and it lets the game cache whatever it caches.
- Force quit the app. Swipe up from the bottom of the screen, pause, and swipe the game away. A game that is still resident in memory can keep working on data it will not have after a cold start.
- Turn on Airplane Mode from Control Center, and check that Wi-Fi is off too — iOS leaves Wi-Fi on if you toggled it back on during a previous Airplane Mode session.
- Reopen the game and play for ten minutes. Start a level, finish it, go back to the menu, start another one, and open the settings screen. The failures almost never happen where you expect them.
- Watch specifically for a stall. A clear “no connection” message is the honest outcome. A spinner that never resolves, a button that does nothing, or a level select that shows empty tiles is the same failure wearing a disguise.
The six ways games break without a network
When a game fails the test, it is usually one of these. Knowing which one tells you whether the game is unusable offline or merely diminished.
| What breaks | What you see | How bad |
|---|---|---|
| Levels are streamed | Level select is blank, or a level opens to a loading spinner that never finishes | Fatal — the game is unplayable |
| Forced interstitial ads | The game waits after a level for an ad that cannot load, then stalls or shows a black screen | Usually fatal, sometimes recovers after a timeout |
| Lives or energy on a server clock | You run out of lives and the timer never ticks down | Fatal once you exhaust them |
| Rewarded ads gate progress | “Watch an ad to continue” with no alternative | Fatal at the moment you need it |
| Login or cloud save required | A sign-in wall on cold start, or progress that refuses to load | Fatal |
| Leaderboards and daily events | A tab shows an error; the rest of the game is fine | Cosmetic |
Only the last one is acceptable in a game you plan to play on a plane. The others all end your session, and four of the six are invisible in the store listing.
What to check before you install
You can skip most bad candidates from the product page alone.
- Compare the download size to the content claim. A game advertising hundreds of levels in a 40 MB download is either very efficiently built or fetching most of it later. Bundled level data is small; bundled art is not.
- Read the in-app purchase list. It is on the App Store product page, and it is the most honest section on it. Entries called coins, gems, energy, lives or moves describe an economy that has to be refilled — often by waiting against a clock or watching an ad, both of which behave badly offline.
- Look for “requires an internet connection”. When it is in the description, believe it. It is usually buried below the fold, in the last paragraph, near the support links.
- Search the reviews for the word offline. Reviews are searchable on the web version of the App Store listing, and travellers are specific: “played it the whole flight” is a different review from “useless without Wi-Fi”.
- Prefer a fixed level set to a generated one. Games that generate puzzles on the fly need somewhere to generate them. Games with a fixed, hand-checked catalog have already shipped it to you.
The honest version of an offline claim
Since we make one of these games, here is ours in the same terms we have just used to judge everyone else.
ColorPath ships all 450 levels inside the app as a fixed catalog that is read from the bundle, not fetched. There is no account, no sign-up and no cloud save; progress lives on the device. There are no lives, no energy meter and no move limit, so there is nothing that can run out while you are offline and nothing that refills on a server's clock.
The part that does need a network is ads, and we would rather say so plainly. ColorPath is free and supported by ads, with a one-time purchase that removes them. Ads are served over the network, so in Airplane Mode they do not appear. The optional “watch an ad for an extra hint” offer is therefore unavailable offline — but every puzzle already carries a free hint that needs nothing, and no ad has ever been the only way forward. The app also checks a small remote settings file at launch; when that check fails, it falls back to the values built into the app and the game starts normally.
That is the shape of an offline claim you can actually rely on: the content is present, nothing depletes, and the network-dependent parts are optional extras rather than gates.
Common questions
Does Airplane Mode really turn everything off?
Not always. iOS remembers if you re-enabled Wi-Fi or Bluetooth during a previous Airplane Mode session and will turn them back on with it. Open Control Center and confirm the Wi-Fi icon is actually off, or turn Wi-Fi off separately before you test.
Does a game with ads still work offline?
It depends entirely on whether the ad is optional. An ad you choose to watch for a reward simply becomes unavailable and costs you nothing else. An ad the game forces between levels can block progress while it waits for a load that will never come, and a rewarded ad that is the only route to more lives is a hard stop.
Why do games download more content after installing?
To keep the App Store download small. Games that generate levels, stream art, or ship assets as on-demand resources fetch the rest on first launch or as you progress. A small store download followed by a large first-run download is the clearest warning that later content may also arrive over the network.
Will my progress sync when I come back online?
Only if the game has cloud saves, and games that do usually want an account. A game that stores progress locally has nothing to sync — which is both the reason it works on a plane and the reason it will not follow you to a new phone.
Try one that passes the test
ColorPath is a colour grid puzzle with no timer, no lives and no move limit. All 450 levels are free and bundled with the app. You can play twelve of them in your browser first, with nothing to install.
