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?


I agree a half finished game isn’t what OP is looking for, and a lot of the gameplay (especially later) revolves around finding your way through what are effectively mazes.
I play it one handed though. It’s turn based combat and when out of combat you just put your finger on the screen and it walks towards it? I didn’t even know a d-pad option existed 😅
The Fight button (I think?) was on the far upper left. So I had to move my lazy left hand AAAALL the way to my phone!
I just had to go back and check we were talking about the same game. There’s no fight button in the default control scheme, you just bump into the thing you want to fight, then a popup shows in the middle of the screen to start the fight.
Ah, I didn’t realize I could just keep bumping into them. I was looking at this Attack button thinking I had to tap that.
Oh that button! That shows after a battle has started. You can tap anywhere! Just tap tap tap on the screen and and long as it’s not a button you’re tapping on then it will attack.
Yeah. I am idiot.
