Hey! I looked around a bit and the last thread like this I found was several months ago, so I thought I'd make a new one.
As per the title, what game do you play on your phone? I'm both looking for new ones myself by also hope others might find some of interest to them.
For my own part of this I mostly like puzzle games, especially these:
Anything I can play with a controller on my PC, because I can stream Steam games to my phone from my PC over the Internet and I have a thing to hold my phone with a Bluetooth controller.
I've wanted to get a holder to join my phone and controller, but I haven't found one that works with any of the controllers I have :/ I'm a sucker for buttons on the underside of controllers and the "official" ones available (xbox elite and dualsense edge) are way too expensive... And those are the only ones that I find phone attachment thingys for.
I have a Gulikit KK3 and it's an absolutely amazing controller, only two small negatives are the lack of the above-mentioned and a headphone jack. Otherwise, it's easily the best normal style controller I've ever used (I have a deep love for the original steam controller, but mine died a while ago and it has some glaring issues that barely make up for all the greatness).
Thought I'd chime in and also recommend GeForce Now and Shadow for cloud streaming on your phone, both work well for specific games. Nothing that needs super quick response times and frame-perfect inputs, but more games than I would have guessed work great!
