Candy Crush (King Games) win Cryptocurrency

Just putting it out there, would be awesome to win coins on these games, and use coins instead of google pay cash to buy stuff. There are 3 games I play now, more of an addiction, Candy Crush, Farm Heroes, and Soda Crush all wonderful ways to unwind and relax. I believe there is money to be made in these games and others. I know there are ICOs and coins out there in the gaming industry, just don't know of any successful ones.
