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:
-
Truly open source (repository available, ideally on F-Droid)
-
No ads, no trackers, no in-app purchases
-
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?
Endless Sky i put this game on basically every device i own lol. i guess it could technically be considered a time waster, the way i play (just take endless mission and ignore the plot) but there is a plot and its recently been more fleshed out. 10/10 would recommend being a space delivery guy
