About the game
Throw a surprise party in 3D. Everyone joins on their own phone and the reveal lands at once.
A host picks a venue and builds a cake, guests arrive on a link and bring something that makes noise, and the birthday person is sent a quiet link that gives nothing away. When the host taps reveal, every phone in the room runs the same fifteen seconds: the lights snap on, everybody’s shout appears above their head, confetti and champagne fire, and a cake with the right number of candles rises out of the floor. Four venues, thirty-two things to bring, a cake you build tier by tier, and a portrait video of the whole thing afterwards for everyone who was there. Up to twenty-four people.
How to play
- Everyone joins on their own phone. You pick the room and the cake, they bring the noise, and the whole thing comes back as a video.
- They pick an avatar, bring something to set off, and write what they will shout.
- Name them, choose their look, then send the one link that gives nothing away.
- Your call, host. Lights out when they are at the door, then reveal.
- Make your wish, then blow at your phone.
