When you arrive at the party


Listen to the introduction delivered by the host. Your host will unlock the “Secrets & Objectives” cards on your device. Read these right away, they’ll give you more insight to your character and guide you on some tasks you’ll need to complete.


Mingle with the other guests as you stay as true to your character as you can. Are you playing an incessant chatterbox? Talk to everyone! Is your character shy? Act more aloof!


Complete the objectives outlined on your card. Make sure no one else sees them or any other character information on your mobile device.
