A lot of really good older games have been ported to mobile and work fantastically. Knights of the Old Republic, Neverwinter Nights, and Baldur’s Gate just to name a few. Hell, you can play Baldur’s Gate multiplayer, cross-platform with PC players even! There’s also fo2.exe on the Play Store, which lets you play Fallout 1 & 2 on mobile provided you have access to the files from the PC versions. Oh, and Doom ports galore, of course.
As far as mobile-only or mobile-specific games, my favorite is probably Caves, a surprisingly well done and completely free roguelike.
Also an honorable mention goes to Organ Trail, a zombie-themed take on Oregon Trail that is, frankly, just a flatly better version of the game in almost all regards. The only reason it’s not my favorite is because the controls on mobile feel awkward compared to the PC version. Still fun though.
Slay the Spire is excellent on mobile, it’s a roguelike deck builder.
Seconding this, it’s one of the very very few mobile games that hold up to the standards of other platforms (probably because it’s on those other platforms as well). It’s not just a good mobile game, it’s an incredible game period.
Slay the Spire is crazy fun. And literally infinitely replayable
Definitely the mobile version of Stardew Valley
Might not be the answer you expect, but I have an iPhone and I got myself an Apple Arcade subscription without expecting much (I didn’t play mobile games at all before that, because they tend to feel either unoriginal, or scammy, or both), and I was surprised at how most games (not all games, but still) were truly original, and none of them were scammy since I was technically paying for them with the subscription. It’s been a surprisingly nice exploration.
On iOS, there’s an AltStore app called PojavLauncher. It’s a launcher for Minecraft Java Edition, which is pretty awesome.
I also quite like the original Angry Birds (now called “Red’s First Flight”), but that’s £0.99.
On Android, have a look at the games category on F-Droid.
Monument Valley, Quarriors, Bastion, Battle Heart Legacy, Marvel Snap, Spades.
Marvel Snap is a really fun lightweight TCG kinda thingy. I never liked Hearth stone or Runeterra, however I thoroughly enjoy Snap
I used to play a ton of rocket league on pc. I was upset at one point by some of their decisions. However i have really been enjoying their free mobile game rocket league sideswipe. It’s different than other games so that ticks the box and there is a lot of room to grow skill wise.
Cytus II, it’s a great rhythm game with a cool storyline
Hate to break it to you, but Rayark replaced it’s art department with AI, so I wouldn’t support them.
Arcaea is good though from what I know, and if not that, there’s also opsu! and the osu! lazer port for android.
World of tanks blitz is amazing.
So is my heroes for RPG
One More Line is pretty great.
RCT classic is pretty good. Not as good as OpenRCT but still quite good.
Slay The Spire is also very good, though the mobile version is a bit bigger than the PC game
I am playing a lot of slice and dice right now. Rogue-like dice rolling game. Available for PC and mobile. Free demo available. If you buy it on Itch.io you get a code for activating your mobile download as well. Absolutely worth the 7 dollars I spent on it.
May be the commercial one but actually Candy crush is a nice one
I work at a gaming company - Candy crush is known for employing the same tactics that keep people sitting at slot machines for 8 hours a day, and every damn PM wants to copy those patterns.
