Royal Adviser is a pass-and-play tablet and mobile game where you and your friends attempt to achieve your secret goals, while taking hidden actions, spying on each other and forming clandestine alliances. One game takes about 20-40 minutes and uses only a single device, making it a perfect secondary activity for a long drive, a boring movie or a bar night with your friends.

Royal Adviser is inspired by the party game Werewolf and the card games Bang! and Coup.

There is a playthrough video in Youtube that explains the rules via a full game playthrough:
