I’m moving away from proprietary apps and want to find open-source games on Android that are genuinely good, not just time-killers or kids’ titles.
My criteria:
-
Modern feel and polished experience — something that feels like a real game, not a tech demo
-
Made for adults: deep gameplay, challenge, real progression (any genre welcome — strategy, roguelike, RPG, racing, puzzle…)
I trust actual players over AI-generated lists, so: what open-source game on Android gave you the best experience, and why?
Idle Fantasy is fun but the gameplay isn’t that deep. It’s basically passive Runescape.
Mindustry, its open source, free, has campaign and multiplayer mode, also available on pc. You can even support devs by buying steam version of the game
+1 to that, mindustry is tons of fun and has builds for most devices. I have personally sunk way too much time into it
Battle for Wesnoth
Hex, turn-based, fantasy game.
Tons of campaigns.

Luanti (previously named minetest)
Block-builder engine, with 100s of game modes.
Mindustry really had me hooked for some time. The devs call it an “automation tower defense RTS”. GPL-3.
Shattered Pixel Dungeon is pretty great if you like graphical top-down turn-based games with procedurally generated maps.

Unciv is basically Civilization 5 with pixel graphics.
There’s a part of my brain that actually prefers Unciv. There’s something very satisfying about mixing complex gameplay and simpler graphics (to me)
Yeah, same actually. The simpler graphics make it easier to understand what’s going on, I find.
And it just uses less system resources, which is good for battery life and being able to keep it running in the background.
Simon Tatham’s Puzzles is my long-time favourite and recently I got really hooked on Water Sort (though that one is a bit lackluster in custom game generation). I don’t know if these meet the progression or even deep gameplay requirements, but at least they are challenging and more or less polished.
Seconding Simon Tatham’s Puzzles, I’ve had a lot of fun with it
SuperTuxKart
Fyi, looks like you’re best off installing via Obtainium if you want auto-updates. The FDroid version is from 2022, so it’s pretty outdated
Breakout 71
I really like Endless Sky!
It’s an open source PC game, but there’s an open source mod for phones on F-Droid.
Edit: i almost forgot the best part! Because the game play relies on text files in a certain format, the PC story mods work with the phone game!
Andor’s Trail is a pretty good roguelike. It goes very deep. Actually, maybe a bit too deep, I have trouble keeping track of everything that is going on! But it is certainly entertaining.
Going to give this a try.
Has excellent quirky humour, from being community built.
Also, make sure to equip some gear. Otherwise, zero combat skills.
I find Feudal Tactics to be a lot of fun.
