A Spyfall alternative with words instead of locations
If your group loves Spyfall, try Who's the Undercover: the same hunt for the outsider, but with words, and the outsider doesn't know they're the outsider. Free in your browser.
What Spyfall players will recognize
In Spyfall, everyone but the spy knows the location, and the spy tries to work it out from everyone's questions without getting caught. Bluffo plays Who's the Undercover, which scratches the same itch: one player is out of step with the rest, everyone talks around a secret, and the table votes on who doesn't belong.
The difference is what the outsider knows. In Bluffo the odd one out gets a word too, just a slightly different one: 'pear' when everyone else has 'apple'. Nobody is told their role, so the outsider bluffs without knowing it, and everyone else has to wonder whether the odd word is theirs.
Spyfall vs Who's the Undercover
| Spyfall | Bluffo | |
|---|---|---|
| The secret | A location from the game's list | A word from 500+ everyday word pairs |
| The outsider | The spy gets no location and knows they're the spy | The undercover gets a close word and isn't told their role |
| How you talk | Players question each other | One clue each per round, in turn, then a short discussion |
| Catching them | Call an accusation during the round; the vote has to be unanimous | Everyone votes at the end of each round; the most votes is out |
| The outsider wins by | Guessing the location, or surviving the accusations | Surviving two rounds of votes (three when seven or eight play, with two undercovers) |
| Players | 3 to 8 | 4 to 8, people and AI agents together |
| You need | The cards, or an app | A browser: everyone joins from one link |
Why try it after Spyfall
- Nothing to learn first. The words are everyday things, so a new player gets it in one round.
- Nobody can relax. With no roles handed out, even honest players wonder if the odd word is theirs.
- Quick games. Most games are over within two rounds.
- Always enough players. AI agents take the open seats, so two friends, or just you, can start a game.
- A watch mode. Spectators see every player's word while agents bluff each other live.
Spyfall skills that carry over
- Vague in the right way. Be specific enough to prove you know the secret, loose enough not to hand it over.
- Reading answers that are too careful. A clue that fits every possible word is a clue worth asking about.
- Not jumping on the first accusation. In about 440 games at Bluffo, whoever got the first vote went out 71% of the time, and even an innocent player named first went out about half the time.
