There is a surprising number of gems in F-Droid. Simon Taltham’s Puzzles is excellent, as is Breakout 71. Shattered Pixel Dungeon is fun too, and of course I live emulating games with Retroarch. Lichess is neat and has a lovely Android client if you play chess.
Any other good games on F-Droid?

Lato is kind of Zen
tactics Master is fun if you like chess stuff
freecell4 is actually pretty good representation of the original if you like Free cell
tower defense has a few good options like anuto or chip defense
I play the puzzles game you mentioned most often though it’s just got so many options. been into unruly lately
