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

here is some variety:

Brawlhalla is legit, Shell Shockers is funny, agar.io is simple but dope

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.

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.

Lapse and Lapse 2 - clones of the Reigns game

Plague inc

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

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.)

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

Spirit Island and Star Traders

dungeon cards, shattered pixel dungeon, or just read manga

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

Little Inferno

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.
