I’m open to options, but I’d especially like to find some that have some sort of real-time, directly controlled primary loop (rather than clicker, or autobattler or that). Basically, while I want it to be an incremental game, I’d still like it to feel like there is a satisfying primary loop.
Also, obvious I’d like to avoid anything pay to win or reliant on microtransactions.
Edit: clarification on primary loop
Edit 2: games in the same style include Berry Bury Berry, A Game About Digging a Hole, Scritchy Scratchy (does have an Android port), and a lot of old Flash games.


Breakout 71 (available on F-Droid) is awesome and is like a souped up version of the ball bounces on paddle to break blocks game. I particularly enjoy the way it controls, when you let go it autopauses the game and unpauses when you click on the screen again. There are different upgrades that you get every round and some of them can get out of hand very quickly!
Unciv is a FOSS recreation of Civilisation V and has an Android version available on F-Droid, it looks pretty neat if you like that sort of game!
And of course, you can always install Retroarch and a frontend (e.g. ES-DE, RetroHrai!, Daijisho, that last one being closed-source while the former two are FOSS) to emulate retro games and, depending on your phone, you can emulate up to Switch! I personally enjoy playing 3DS (horizontally) and GBA (vertically) on my phone. You might also like Lemuroid, which is an emulator that is configured well OOTB but less flexible than Retroarch.
I don’t think any of those are incrementals, though :)
I’m sure in the massive catalogue of retro games that can be emulated at least one is an “incremental” game.
Breakout 71 is actually really fun though, you should play it!
Yeah I installed that one, will check it out :)
