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?


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
