Shattered pixel dungeon

All games on fdroid

I've enjoyed ports from PC games and emulation. Emulation is pretty good on android now, and that opens up a LOT of options for offline & no ads

Unciv is a decent Civilization clone. And it's open source.

Shattered Pixel Dungeon
Mindustry

Bloons TD 6

Almost every paid Kairosoft games?

Terraria

1. Any Playdigious games is good.
2. Any Kairosoft games.
3. ICEY is such an underrated game. The narration and it's wit is so good.
4. Levelhead if you want platformer and want Super Mario Maker on your phone.
5. Limbo

Slay the Spire is a heavy recommendation from me, though it does have online sync it works nicely offline.

Stardew Valley, 10/10

Shattered pixel dungeon if you like roguelikes; it's on the play store and fdroid

My goto for offline gaming is usually emulation, typically pokemon. But I can also recommend the Bart Bonte puzzle games, Vampire Survivor and Shattered Pixel Dungeon.

I quite enjoy Hoplite.

Puzzles - no internet, no cost, no pay-to-win, no ads, no fancy UI, just classic logic puzzles!

Simon Tatham's puzzle collection is my fallback game for whenever I don't have internet or am bored with whatever other game I'm playing

Dead Cells & Titan Quest. Both are amazing games, work totally offline, no ads.

If you like American football, big recommend for Retro Bowl - as the name suggests, it's an old-school arcade/NES style game heavily inspired by Tecmo Bowl. Plays really well on mobile, and has a small premium charge to permanently unlock some nice extra features (e.g. roster customisation).

Similaritron (seems abandoned, but still works)

If the game does not need online features, then you can make any game "ad free" with an app like "NetGuard". Just block the app from accessing the internet.

Mindustry and Unciv are my main recommendations. If you like strategy stuff, you'll have a blast.

Found an old archive so I'm going to ad to the thread myself:

Alto's Adventure and Alto's Odyssey both definitely work offline, but I'm not sure about them trying to serve you advertisements.

I also used to have a considerable library of emulated games on my phone and would use a bluetooth gamepad. I should probably go back down this road I think! I'd imagine emulation has come a long way since I was mucking around with it.

I've been really enjoying Pocket City !pocket_city@lemmy.world

antimine is a fun and well made minesweeper clone, also its foss

On this topic I wish there was a definitive place to find Android games that have controller support. No microtransactions.. I will have to download and try again first and then 90% of the time it doesn't meet my criteria for playable.

Slay the Spire is a heavy recommendation from me, though it does have online sync I'm pretty sure it works offline...

I believe Kotor 1 doesn't require a connection to play, and it's more of a tactical game, so it's not as annoying to play on a touch screen.

Battle for Wesnoth is cool once you get used to the weird controls

Unciv and Shattered Pixel Dungeon have been on my Phone forever. Both available on FDroid.

DATA WING, is a great game! Really well made, easy to pick up for a few miniuits and really well scripted!

Yioto is a great indie dev with lots of gems, but if particularly recommend Antiyoy.

I'd also recommend Battle for Polytopia.

I'm fairly certain both these turn based strategy games will work fine offline.

Unciv and Mindustry, both which are also free, on fdroid, and open-source.

every game is ad free is you use pi-hole

Hocus. It's a MC Escher puzzle solving game! Google play link

Patience balls

Endless Sky is a space fleet building, trading, battling, exploration game. Free and open source.
