What Is the Impostor Game? Undercover, Spyfall & Mr White Explained

Impostor is a social-deduction party game where most of the room shares a secret word — but a hidden few are faking it. It sits in the same family as Spyfall, Undercover and Mr White, and it's built for 3 to 10 players around one phone.

The roles

• Civilians — the majority, who all share the same secret word.
• Undercover — get a similar-but-different word, and don't even know they're the fake.
• Mr White — gets no word at all, and must bluff a clue to blend in.

How to play

Pass the phone so everyone secretly peeks at their card. Then take turns describing your word without saying it outright. After the clues, the room debates and votes someone out. Civilians win by catching every fake; undercovers win by surviving; and Mr White can steal the whole game with one lucky guess of the secret word.

How it compares to Spyfall and Undercover

If you've played Spyfall, the tension is familiar — someone at the table doesn't know what everyone else knows. Undercover and Mr White add the twist that the fakes get a near-miss word (or none at all), so the giveaway is a clue that's just slightly off. Impostor blends all three, with home-grown Kenyan words.
