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.
Shattered Pixel Dungeon is your friend, then
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
Mindustry really had me hooked for some time. The devs call it an “automation tower defense RTS”. GPL-3.
Battle for Wesnoth
Hex, turn-based, fantasy game.
Tons of campaigns.

Luanti (previously named minetest)
Block-builder engine, with 100s of game modes.
I wonder if mobile version of Cataclysm-DDA is open-sourced, like the desktop one. It is probably the most mechanically complex zombie-survival roguelike you can find
It’s on GitHub, so I believe it is.
https://github.com/a1studmuffin/Cataclysm-DDA-Android/releases
That repo says that it Is no longer maintained and to check this repo instead:

(There are official Android releases now apparently)
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.
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)
Shattered Pixel Dungeon is pretty great if you like graphical top-down turn-based games with procedurally generated maps.
Astro Loop, roguelike shooter

Surprisingly addictive
Yeah I’ve been playing a lot of that one lately. Sorta Vampire Survivors plus Asteroids.
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!
