Hello, sorry you have not been asked to view adverts. If you have not made any purchases  just wait untill you are put in a test group. king does rotate different events for most people. Also about what @Lindark   said  its not true. Your adverts may only be  gone for a few months or even a year or maybe forever it depends on king as mentioned above by  @kiara_wael. Just hang in there because you never know when king might or might not give them to you.

This feature also disappears forever once you make a purchase in the store.

Hi and Welcome to the King Community

Thank you for the feedback. The video ad feature as all ads and promotional features is still a test feature in the game, which means that some of you can get Lives, while others can get Boosters or other items from this feature.

This also means that the video ads will not always be available and not found in all player's games or on all devices.

So if you at the moment are missing the ads in your game, just stay tuned and keep an eye in the game to see when the ads are back.
