Category of App/Game that is earning you income?

Which category of App/Game is earning you income?
My case is Puzzle Game earning me around $20 to $30 a day.

I think the most of us will not tell, that means more apps in the same category , more competition and bad futureā€¦ :smiley:

Many of the Dev always tries to keep their earnings to themselves. From what I see $20 to $30 a day is really good. Keep it up
