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

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

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.

Lichess :P

Tetris. Pac-Man 256. Brick Breaker Quest. for Tetris at least you'll want to make sure that you've got an adblock DNS set up because it's full of ads otherwise

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.

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

It's not an arcade-style game by any means, but I can't recommend "Sky: Children of the Light" enough! My partner and I have been playing it daily for over 4 years and still can't get enough of it. It's hard to give it a proper description. It has a beautiful storyline with new seasonal stories that come out every 3 months or so. You play as a child of light whose mission is to banish darkness and shepherd spirits from a post-apocalyptic land into the stars. However, the real core of the game is the social aspect. It's mmo-adjacent (typical server sizes are 8 players) with other players showing up as other children of light. You slowly make friendships using in-game currency and gifting each other friendship levels. You cannot chat with others at first and must communicate through a variety of emotes until you unlock chat in the friendship tree. The way communication and friendship is handled in the game makes it one of the most friendly and least toxic communities that I've found on the Internet. It's also cross-play and cross-save between Android, iOS, Switch, PlayStation, and Steam. That Sky Game

Survivor.io is actually amazing and doesn't panhandle your for money

Bloons TD6 is great and will melt your life away

Pawnbarian is a good twist on chess

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.)

You didn’t say what OS you were running, but if you’re running an iPhone, the original Sonic is in the App Store and is pretty playable on a phone. I also really liked Temple Run.

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