I also like, from f-droid, Tower Jumper, and from Play, hillclimb racing.
seen much praise of mindustry here on Lemmy, but not got into it myself
rabbit escape is like lemmings/pingus
I like go, but play casual. CrazyStone on Play works well for me. It’s doing something with the internet on startup, probably benign model updates, but I block its internet access.
I also remember Doom and Destiny being very fun and fairly casual. The free version is not too bad on ads. The second one I never got far in - felt like it was constant ads interrupting gameplay
