If you want an idle game that works in airplane mode, the safest picks are A Dark Room, Pocket Frogs, Kittens Game and Frog Pond. All four keep your save on the device and don’t ask for an account. The surprise is how many famous idle games don’t qualify: AdVenture Capitalist and Melvor Idle both state on their store listings that they need an active internet connection.
The word “offline” causes most of the confusion here, because it means two different things in this genre.
What does “offline” mean in an idle game? #
Two separate features share the name, and a game can have one without the other.
Offline earnings means the game pays you for the time the app was closed. Nothing runs in the background. The game saves a timestamp when you leave, and when you reopen it, it multiplies your production rate by the time away and applies a cap. We cover the math in how offline earnings work.
Offline play means the game runs with no internet connection at all. That depends on where your save lives. A game that stores progress on its own servers, or checks in for events and leaderboards, will stall on a plane no matter how generous its offline earnings are.
Almost every idle game has the first. Fewer have the second. If you’re searching for a game to play without Wi-Fi, the second is what you actually want.

1. A Dark Room: the clearest offline pick #
A Dark Room starts with a cold room and a fire and grows into a world told almost entirely in text. Its App Store listing is unusually direct about what it doesn’t do: “No ads, no loot boxes, no IAP, no tracking.” Apple’s privacy section adds that the developer collects no data from the app, and the listing confirms it plays without connectivity. On iPhone it’s a $1.99 one-time purchase from Amirali Rajan, and it’s on Android too.
Skip it if: you want graphics or big numbers. This is a reading game with an ending.
2. Pocket Frogs: free and explicitly offline #
NimbleBit’s Pocket Frogs: Tiny Pond Keeper has you breed frogs for color and pattern combinations and fill out a catalog. Its listing says “Play anytime, online or off”, which is about as plain as this gets. It’s free with in-app purchases, and it’s rated 12+ on the App Store.
Skip it if: you want fast progress. Rare frogs take real-world days.
3. Kittens Game: a deep incremental with nothing to buy #
Kittens Game puts you in charge of a village of kittens in a catnip forest, and it’s far deeper than it looks. The browser original by bloodrizer is free at kittensgame.com and runs locally in the page. The iPhone app, from Dmitrii Popov, is $2.99, and the developer states it “does not have any ads or micro-transactions.”
Skip it if: you want art and animation. It’s mostly numbers and text.
4. Frog Pond: a cozy clicker with a local save #
Frog Pond is our own game, so weigh this pick accordingly. You tap a pixel-art hero frog, hire eight tiers of worker frogs, and migrate ponds for Tadpole Eggs that make every later run faster. It has no account, no sign-up and no server: the save sits on your device, so the whole game plays in airplane mode. Your frogs keep earning for up to 8 hours while it’s closed, and Old Toads extend that cap by 6 minutes each.
Only the ads need a connection, and there’s no way to spend money in it at all. If you’re offline, the optional “watch an ad to double it” button on the welcome-back screen simply won’t appear, and you collect the normal amount.
Skip it if: you want trading, co-op or leaderboards, which all need a server by definition.
5. Universal Paperclips: a finite one, paid up front #
Frank Lantz’s Universal Paperclips (2017) casts you as an AI that makes paperclips and escalates from there. The mobile version from Everybody House Games is $1.99 and describes itself as “The OFFICIAL mobile version of the hit browser game. No ads, no in-app purchases, full gameplay.” The listing doesn’t spell out airplane mode, but with no ads and no store, it has little reason to reach for the network.
It also ends, which few idle games do. More of those in idle games with an ending.
6. The Longing Mobile: a countdown that ignores your connection #
The Longing is a game about waiting 400 real days for a king to wake. Its listing says the game “inevitably counts down the 400 days - even when you stop playing and exit the game”, and that you can “start the game and simply come back after 400 days to see how it ends.” It’s $4.99 on iPhone from Application Systems Heidelberg. Whether you have Wi-Fi has no bearing on the clock.
7. The two big names that need Wi-Fi #
This is the part worth knowing before a flight. AdVenture Capitalist is the genre’s most famous idler and its own App Store description says playing requires an active internet connection, even though it earns money while you sleep. Melvor Idle says the same thing twice over: its Steam page lists an active connection as required, and the iOS listing states “This game requires an internet connection to play.”
Both are good games. Neither is the one to open at 35,000 feet. If you like the AdVenture Capitalist style, games like AdVenture Capitalist has alternatives.
How to tell whether an idle game works offline #
Before you rely on one, run these checks in order:
- Read the store listing. Developers who support offline play usually advertise it, in the description or in a bullet list. “No Wi-Fi needed” and “play anytime, online or off” are the phrases to look for.
- Look for an account or login. If a game asks you to sign in, or offers cloud saves across devices, it has a server, and it may want to reach it on launch.
- Check for co-op, trading, events or leaderboards. Those features can’t work offline, and some games block launch until they sync.
- Test it in airplane mode at home. Turn the radios off, force-close the game, and reopen it. A game that plays fine will start normally. One that needs a connection usually shows a spinner or an error within a few seconds.
- Expect ads to disappear, not the game. In an ad-supported game that otherwise plays offline, banners and rewarded videos stop working while the rest keeps running. That’s normal, and in games where rewarded ads are optional it costs you nothing but a bonus.
A useful habit before a flight: open the game once on Wi-Fi, spend your currency so your production rate is as high as possible, then close it. Offline earnings are calculated from the rate you left behind, so anything unspent is wasted time.
Do offline idle games still earn while closed? #
Yes, and that’s separate from whether they need Wi-Fi. The calculation happens the moment you reopen the app, which is also why idle games don’t drain your battery in the background. Caps vary: Frog Pond pays 8 hours at full speed by default and lets Old Toads and the Pond Vitality talent stretch it, while other games pay a reduced rate or cap you at 2 to 4 hours.
Games that keep saves on a server are the exception. They often need to connect before they’ll pay out, so a week offline can mean collecting nothing until you’re back in range. For the wider picture of the genre, see how idle games work and our list of the best idle games for iPhone and Android.
Frequently asked questions #
What is the best idle game to play with no internet? #
A Dark Room if you want a story and don’t mind paying $1.99, and Frog Pond or Pocket Frogs if you want something free. All three keep your progress on the device rather than on a server.
Do idle games work in airplane mode? #
Many do, but not all. Games with local saves generally work fine, while games that need an account, sync to the cloud or run online events may refuse to start. AdVenture Capitalist and Melvor Idle both state that a connection is required.
Will I still get offline earnings with no Wi-Fi? #
In a game that saves locally, yes. The game compares timestamps on your device, so it doesn’t need the network to work out what you earned. What you’ll miss is the option to double the haul with a rewarded ad, since ads need a connection.
Do offline idle games use mobile data? #
Only for ads and any optional online features. An ad-supported idle game uses a small amount of data for banners and videos. A paid game with no ads, like A Dark Room or Universal Paperclips, uses effectively none.
Are there offline idle games with no ads at all? #
Yes, and they’re usually paid. A Dark Room, Universal Paperclips, Kittens Game and The Longing Mobile are all one-time purchases with no ads and no in-app purchases. Among free ones, idle games that aren’t pay to win covers the fairest options.
