I want to activate ads in the game

Hello @saidos it is not possible to get a game feature activated just by asking for it. Every feature of Candy Crush is randomly delivered to groups of players by King, so you either have a feature or you do not. If you haven't got a particular that you would like all you can do is wait and hope that King eventually deliver that feature to your game. Unfortunately there is always the chance they will never deliver a particular feature to your game.
