What kind of games do you like, @avi0lpz ? I could recommend a few time management or hidden object, if that's what you're looking for!
I can only recommend apps for iOS because I don't have the Android platform, so you'd have to check and see if these are available for that if you have Android.If you like jigsaw puzzles, there are some great apps in the iTunes store that are free. I have 3 that I rotate through.For puzzle games, I really like Two Dots. It's relaxing, but also offers some good challenges. It's pretty addicting, though.If you like the drop style games similar to Candy Crush, Farm Heroes Saga and Cookie Crunch are good.
