If you have a rooted phone, an older android version, or the ability to access the android/data folder to move files around, I hear some pvz2 mods are pretty good. Only ones I can personally say are good are Refloureshed and Eclise, though it's been a long time since I've played Eclise. Both are harder versions of vanilla.

Alto - very calming and engaging game where you go down a mountain on your snowboard trying to catch llamas and do aerial tricks. Excellent vibes, no bothersome ads or micro transactions i think.

Night of the Full Moon is incredible.

Sky Force and Kittens Game are the only two mobile games I ever played and still have installed on every phone

Minesweeper on fdroid

If you like puzzles, horror and all things weird, definitely try some of the games by Rusty Lake.

The entire Cube Escape series is available for free (a sort of excape the room puzzle).

Reigns is quite fun

I've rather enjoyed 20 Minutes Till Dawn

Board game adaptations tend to be good. Everdell and bottom of the ninth for preference.

Monument Valley 1 and 2.

Haven't found anything that isn't microtransaction and ad-riddled trash or a port of an older game since.

Le Parker is my favorite side scrolling platformer on mobile that no one knows about.

There's an app I really like called Minireview, focused on finding and reviewing mobile games.

I Love Hue and I Love Hue Too. Also, My Friend Pedro. That one's pretty short though.

Atomas is pretty fun, it's super simple and looks really good

Slay the Spire. Join us.

• Monument Valley is an amazing mobile game although not arcade style
• Alto's Adventure/Odyssey are pretty solid
• Duet is a great arcade style game
• HyperRogue is a neat non-Euclidean roguelike https://roguetemple.com/z/hyper/

• Another vote for "Slay the Spire", have bought it for all platforms and wasted too much of my time
• Horizon Chase Turbo is a very good arcade racer
• Danmaku Unlimited 2 and Danmaku Unlimited 3 for bullet hell shmups

Not arcade style, but Final Fantasy I-VI pixel remasters are IMHO great on phones.

Super auto pets is incredibly based

I Love Hue, both 1 and 2

Dunno if anyone mentioned Badland yet.

Looks difficult to play but is so well designed that it isn't

Peglin is super fun. It's wood-described as a peggle rouglike

Fancade is also great. It's an open engine for little arcade games, so there's always something new to play. There's different modes like an adventure mode and a battle mode. There are IAP's but they're purely optional and very unnecessary.

All games I'm going to mention aren't sending me any notifications.

Square on top is a bit like jump king, and let's you disable 'unwanted' Ads. You're still able to watch ads for your own gain, but dont have to.

Divineko is a fun shape drawing/reaction game that has very fair ad placements IMO.

Xeonjia is an ice puzzle game (you walk in one direction until you hit a rock) that reminds me a bit of Pokémon with its art style. I dont think it has any ads.

Those three are my go to's currently.

Try 'A dark room'. It's a bit different, but it had depth and your can get into it. I also still love 'Plague inc.'.

Super Auto Pets is one I like

There are plenty of puzzle-style ones like Sagadoku/Blockudoku, Minesweeper, etc.
