Picross Luna
Picross Luna 2
I'm a bit late to the fad, but I've been playing Picross Luna all week and can't stop. It's a simple game with nice, relaxing colours, and a ton of levels.
Here you go, OP.
I didn't review them but this are all the low spec, portrait perspective games I recommend.
Edit: I reviewed some becuase they were the most memorable, the non reviewed ones aren't bad but I have been playing Android games for about 5 years so it's a lot that I have forgotten.
I just counted them and it's 64 games,

I have been doing picross for a few weeks now. Decent enough for a basic puzzle. https://play.google.com/store/apps/details?id=air.com.coworkdream.PicrossLUNA
