The short version: there are a handful of scary Android games that need zero data once downloaded, and most "offline horror" lists online are wrong because they include games that need a connection for ads, saves, or the opening tutorial. I tested this the only way that matters: turning on airplane mode and seeing what launches.
I run my business life on apps that need wifi for everything, invoicing, scheduling, email, the lot. So when my nephew asked me for horror games to play on a long train journey with no signal, I went looking. What I found is that "free offline horror" is one of the most badly answered questions on the app store review sites. Half the listicles are copy-pasted from each other and nobody has sat in a dark room with the wifi switched off to check.
Why most "offline horror" lists lie to you
Here is the uncomfortable bit nobody wants to say in a cheerful listicle: a lot of games marketed as "offline" still phone home the second you open them, either to validate a licence, load an ad network, or sync a save file to a server. If you are somewhere with no signal, a remote cottage, a flight, a basement with no bars, that game will sit on a loading screen forever. The only honest test is airplane mode. Download the game on wifi, switch to airplane mode, force close it, then reopen it cold. If it works, it is offline. If it stutters or demands a reconnect, it was never offline to begin with, it just didn't mention the catch in the store description.
That single test eliminates roughly half of what shows up when you search "free offline horror games Android" on the Play Store. The games below passed it.
Games that run with the wifi off
- Eyes: The Horror Game (free, has ads but they load before you start) - you are breaking into a haunted house to steal gold and something is hunting you. It is short, around 10 to 15 minutes a run, which makes it good for a train journey rather than an all-nighter.
- Granny (free) - you wake up trapped in a house with an old woman who will kill you if she hears you. Entirely offline once installed, no story to speak of, pure mechanical tension. This is the one that makes people jump in a dark room because the audio cues are the whole game.
- Mr Meat (free) - a puzzle-horror where you are chained up and need to solve escape puzzles before a butcher finds you. Slower pace than Granny, more thinking than running, which suits people who want dread rather than a heart attack.
- Dreadout: Keepers of the Dark (free, paid DLC exists but the core game is playable without it) - a side-scrolling horror platformer, lighter on jump scares, heavier on atmosphere, and it does not need a connection once the initial files are downloaded.
- Slendrina: The Cellar (free) - one of the oldest mobile horror games still going, and it still works completely offline because it was built for phones with far worse connectivity than we have now.
Here is a specific example of how this plays out in practice. Say you run a Halloween night for a group of teenagers who will inevitably end up somewhere with patchy signal, a garden shed, a basement, a tent. Download three or four of the above on home wifi beforehand, test each one in airplane mode before the night starts, and you have a backup plan that does not depend on whoever has the best phone signal in the group. That is the actual value of knowing which ones are offline, it is not about saving data, it is about the game working when and where you need it to.
What "free" costs you
None of these are secretly paid games, but free horror apps on Android make their money one of two ways: ads between rounds, or in-app purchases for cosmetic extras and extra lives. The ad-funded ones are the better bet for a offline evening because once the initial ad has loaded (which needs a connection), subsequent play sessions in airplane mode just skip the ad slot entirely rather than hanging. The in-app-purchase ones tend to be cleaner offline because they are not constantly trying to serve you a new ad, they just nag you to buy a key or a torch upgrade, which you can ignore.
A quick setup routine before you go dark
- Download your chosen games at home on wifi, not on mobile data, since horror game files run 100MB to 400MB each.
- Open each one once while still connected so it can do its first-run check and any licence validation.
- Switch to airplane mode and force close the app completely, not just minimise it.
- Reopen it cold. If it loads straight to a menu or gameplay, you are sorted.
- Turn your screen brightness down and your volume up before you play in the dark, since these games lean on audio far more than visuals.
That five-step routine takes under ten minutes and it is the difference between a smooth dark-room session and a frustrating one where half your battery goes on a spinning loading wheel.
Storage and battery, the bit nobody mentions
Horror games with decent atmosphere are not small. Budget 1.5GB to 2GB of free storage if you are installing three or four of these, because the audio files that make them creepy take up real space. And if you are playing in the dark for an extended stretch, your screen is already at a lower brightness which helps battery, but the constant audio processing on these games drains a phone faster than a simple puzzle game. A fully charged phone will give you roughly two to three hours of continuous horror gaming rather than the five or six hours you'd get from something like a word game.
If you want a wider spread of things that work with zero signal, not just horror, the no internet games list covers over a thousand options across Android, PC and iPhone, and it is worth a look if the group you are entertaining is not all into horror. For Halloween specifically there is a separate roundup of Halloween games that play offline on your phone, which leans more festive and less terrifying if you need something for younger kids in the mix, and a set of Halloween party games for adults and kids if the horror apps are too intense for part of the group.

If you want the general method for working out whether any app, horror or otherwise, is really offline rather than just claiming to be, I wrote up the full test process in how to find offline games that truly don't need wifi. It applies exactly the same way to horror apps as it does to anything else, the airplane mode test does not care what genre you are downloading.
What to skip
I would steer clear of anything advertised as "multiplayer horror" for an offline session, obviously, since those need a server connection to match you with other players and will simply fail in airplane mode. Also be wary of anything that asks for an account login before you can play at all, because that login check almost always needs a live connection even if the gameplay afterwards does not. If a horror app forces a sign-in screen before showing you a single frame of gameplay, it is not a safe bet for a no-signal evening.

Frequently asked questions
Are there any free horror games for Android that work with no internet at all?
Yes, Granny, Mr Meat, Slendrina: The Cellar and Eyes: The Horror Game all run completely offline once installed, provided you open them once on wifi first to let any first-run checks complete.
Why do some offline horror games still ask me to connect to wifi?
Usually it is ads, since many free games try to serve a new ad slot and will show a loading wheel if there is no connection, or it is a save-sync feature. Test with airplane mode before you commit to playing in a signal-free spot.
How much storage do offline horror games need on Android?
Budget 100MB to 400MB per game, so three or four titles will need 1.5GB to 2GB of free space, mostly for the audio files that make the atmosphere work.
Do offline horror games drain battery faster than other mobile games?
Yes, generally. The heavy audio processing that creates tension uses more power than a simple puzzle game, so expect two to three hours of play from a full charge rather than five or six.
