Little Inferno

Shattered Pixel Dungeon Loop Hero Pirates Outlaws

I install a few others every now and again to try new things, but it's usually ad-driven / endless predatory MTX bullshit.

Hill Clim Racer has been a long time favorite. Still works great in airplane mode and well.

Lapse and Lapse 2 - clones of the Reigns game

Plague inc

Tyrian. 90's scrolling shooter ported over and mostly functional.

Lichess :P

I've been playing Shattered Pixel Dungeon, which is an actual roguelike game.

Egg Inc is angrowth game that's silly and fun. Squad Alpha is a great casual shooter, and all ads are voluntary. (Note, this is NOT Alpha Squad.)

As far as puzzle games, SevenBloks is my most played game by FAR. I play on Toughness mode, and the games are pretty quick. It’s a combination of equal parts strategy and luck.

For sports games, Retro Bowl & Retro Bowl College (American football) are the best $1 per game I’ve ever spent. I’ve lost track of the number of seasons I’ve played on both.

Bomb Club on iOS (was on Android at one point)

Jetski.

I’m on iOS and actually pay for Apple Arcade. It’s been worth it. I don’t bother looking anywhere else for mobile games anymore.

Spirit Island and Star Traders

dungeon cards, shattered pixel dungeon, or just read manga

Other's have suggested emulating Pokémon. However, if you want a native RPG, the first six Final Fantasy games were remastered for mobile. That's five whole good games! They all have very frequent auto saving, so they're pretty easy to just pick up and put down.

These aren't arcade-y, though. Others have already suggested the best. I like Super Hexagon the most of the suggestions due to its simplicity. Geometry Dash is also great, but sometimes, it just isn't sightreadable.

AAAAXY is an incredibly trippy puzzle platformer available on F-Droid.

Balloon Fight is hilarious and a stomper

Did you try qr コード 読み取り for more?

Balatro, when it finally gets ported to mobile. It's probably right up your alley.
