I use Mini Review for most of my android game finding. I find that if they give an overall score of 8 and above, I almost always like the game.

I'm currently enjoying the idle clicker Magic Research 2 It doesn't feel like most idlers. There's monsters to fight that need some strategy and a pretty good plot where I actually read everything! Most games have plot that is so boring and rehashed that it's not worth reading, but Magic Research 2 was a lot of fun. I played the demo a bit and bought the full version before running into whatever limits were in the demo.
