Imposterus

One theme. One Imposter. Can you spot the traitor before they guess the truth? A fast, fun party game for friends.

Imposterus is a social deduction party game where trust disappears and every word can betray you.

Each round, players receive a role and a shared theme. Everyone knows the theme — except one secret Imposter.

The Imposter must blend in, ask the right questions, and guess the theme without being exposed. The other players must listen carefully, analyze answers, and uncover the traitor.
