Russian roulette but instead of pulling the trigger on a revolver, I install apps at random and see if my phone gets assimilated into a Muscovite cryptominer botnet.

Shattered Pixel Dungeon

There are many 2048 clones out there, but this is the best I have found on F-Droid

Block drop, a tetris clone. Also OpenMW but you need to buy Morrowind to play that

Frozen Bubble, VCMI & Powder Game.

Gurgle (wordle clone) and Gridle, word games. Cards With Cats is very good if you like to play Hearts. Ball2box, it's all in the name. Super Retro Mega Wars has some serviceable classics like asteroids and Tetris. SuperTuxKart is alright. Simple Solitaire Collection isn't maintained anymore, but hasn't been surpassed yet on f droid imo. Getting good mileage out of Lemuroid of course, the console emulator for people who don't like configuring things.

Open Sudoku is neat if you like Sudoku.

Idle Fantasy is really great. I love it.

I really like Gaugin. It is similar to SoDuKo, but a little more math. I also like to play Freebloks, which is like the board game Blokus.

I like HyperRogue and recently installed Braincup, but that's a bit intense.

Unciv

Also works on desktop Linux

I haven't finished it, but I thought Xeonjia: Ice Adventures was pretty good. It's a combination of sokoban and adventure games where you navigate the world by solving block puzzles.

Currently playing MA Pipes. It's a nice puzzle game.

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
