How to you pass the king thing to another?

If you are talking about that super annoying king from the Royal Match ad, there's not much you can do to get another video ad. You might try an ad blocker; where you still have to wait 35 sec to play, but that's better than sitting through that ad. Also try going into your game settings (green gear icon), selecting "advanced" tab, and selecting or unselecting the "personal ads" and see if that changes your ads. If that doesn't help, take the ad time to close your eyes and mentally prepare for JJ game, breath deep, hand/finger stretches, etc. They can put an annoying ad in front of you, but they can't force you to watch it.

Do you mean being the team captain or leader? They have a crown next to their name. I don’t know how to do that but perhaps search answers about team captain and/or ask the question again.
