Let’s playYour phone is your secret card
4–12 players join one room on their own phones. Internet is required; no account or download. Play in person, or use a separate voice call with remote friends.
Read your word. Keep it secret.
There is 1 undercover among 4–7 players, or 2 among 8–12. Civilians share one word; undercovers receive a similar word. You see your word but not your team. The host cannot see anyone else’s word.
Take turns describing
Once everyone confirms their word, describe it in one sentence when prompted. Do not say the word, translate it, or use a sound-alike clue. Speak in person: the game does not record audio. Tap “I’m done” afterwards. The host can only skip an offline speaker.
Vote in secret
Every surviving player votes for a suspect other than themselves. Votes cannot be changed after submission and remain private until voting ends. Results are counted once everyone votes or the timer ends; missing votes count as abstentions.
Ties and elimination
A unique top-voted player is eliminated. Their team, but not their word, is revealed. A first tie triggers one runoff between the tied players. Another tie or no votes means no elimination. The starting speaker rotates each round.
Who wins?
Civilians win when all undercovers are eliminated. Undercovers win when surviving undercovers are at least as numerous as surviving civilians. All words and teams are revealed at the end. Everyone on the winning team, including eliminated players, earns a win. The host can return to the lobby for another game.
Reconnect to your seat
Refresh in the same browser to reconnect. A new tab for the same seat takes over from the old one. An online player becomes host after the host is offline for 30 seconds. Seats cannot join or leave during a game; the host may end the game and return everyone to the lobby.
Rooms and privacy
Rooms expire 24 hours after their last game action. Your browser stores a reconnect credential and language; the server stores nicknames and temporary game state. No chat, advertising, or payments. Leave your seat before handing over a shared device.
