Id highly suggest ezpzrpg its been a fun game for my friends and I. You really only have to check it once a day, but there is a surprising amount of stuff to do if you want to sit down for an hour and play it.
Really good for anyone who likes rpg games, and the feeling of having an upgrade drop that means you finally get to kill the boss you've been stuck on!
Here's my apk file that I took from my phone

So, you want a game that you don't even have to play? https://play.google.com/store/apps/details?id=com.nuclear.qmwow.platform.r2game I think that's what you're looking for.
Might you be talking about this game: EZ PZ RPG?
EZ PZ RPG (released April 2015)?
just ignore the paid-thing and it would be a good game ;)

Maybe EZPZ RPG? You don't need to leave it open, just you need to login (so you need wifi/mobile) and check in on your character, update their gear, get them to fight a boss to fight stronger mobs which drop better gear, etc.
