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?


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
