Features

Everything your crew needs
for the perfect game night

Designed to be picked up instantly and put down laughing.

🎭

Mafia, with a Real God

One friend runs the night as God, with every role on their screen. Open voting shows who voted for whom. The God can mark players out, remove them, or swap a role mid-game.

🔥

Truth or Dare

Pick your packs, spin, and take your turn. Everyone sees the prompt and reacts live.

📷

Scan & Play in the Browser

Everyone scans the room's QR code with their phone camera and plays in the browser. Nothing to install. Add it to your home screen if you like.

🔑

Sign In with Google

One tap and you're in. Your name and your place in the room follow you, even if you switch phones or browsers.

📶

Drops Don't Stop the Game

A locked phone or patchy Wi-Fi reconnects quietly and the game keeps going. If the God's phone dies, someone else can take over.

⚡

Real-Time Multiplayer

Every vote, turn and reaction shows up on everyone's phone instantly, for groups of up to 40.
