This guide describes rules and mechanics actually available in the Blefuj game.
Impostor is a fast bluffing-and-deduction game for 3–10 people on one phone. Most players know a secret word; one or more impostors don't and must pretend they do. Below you'll find the complete rules, an example round and tips.
Setup
- Set the number of players (3–10) and how many impostors.
- Pick a word category, e.g. Food, Movies or Travel.
- Decide whether the impostor gets a gentle hint (hint mode).
- Enter names or play anonymously, names stay on your phone only.
Revealing roles
The phone travels around the group. Each player reveals their role on a private screen, one at a time, so nobody else can see it. Civilians see the secret word; the impostor only sees that they're the impostor (or a gentle hint if you enabled that mode).
Important: don't show your role screen to others, and only pass the phone after closing your card. The next role never reveals itself automatically.
The round and clues
Going in turns, each player says one word or a short association linked to the secret. Civilians want to prove they know the word without giving it away too directly. The impostor bluffs, listening to others and blending in so as not to break the rhythm.
- Too obvious a clue hands the word to the impostor.
- Too vague a clue makes you look suspicious yourself.
Voting and the result
After the clue round the group discusses and votes on who the impostor is. Catch the impostor and the civilians win. If the impostor survives, or correctly guesses the word, they win. Then you can play another round with a new word.
An example round
Category: Food. The civilians' word: “pizza”. The impostor doesn't know it. Clues in turn: “Italian”, “round”, “with cheese”, while the impostor plays it safe with “warm”. It sounds neutral but too generic, and that's exactly what draws the group's attention at the vote.
A second example round
Category: Travel. The civilians' word: “airport”. Clues in turn: “suitcase”, “queue”, “passport”. The impostor, not knowing the word, offers “far away”, it fits travel but not the specific place. In the discussion someone asks for a detail and the vague answer gives them away. Had they caught “passport” and “queue” earlier, though, they could risk a sharp “check-in” and survive.
Common player mistakes
- A civilian gives an obvious clue and hands the word straight to the impostor.
- A civilian is so cryptic they look as suspicious as the impostor.
- The impostor talks too much, the more detail they invent, the easier to catch.
- The group votes in silence with no debate, yet the debate is the best part.
- You reuse the same category every round and the game gets predictable.
Rule variants
- Two impostors: with 7+ players it adds chaos and quiet alliances.
- Timed round: ~10 seconds per clue, pressure exposes bluffing.
- Last chance: a caught impostor still wins if they guess the word.
- No hint: a harder mode for experienced groups.
- Silent round: write clues down and reveal them all at once.
Settings by player count
How many impostors, whether to use a timer and which category to pick should all depend on your group size, a game of 3 plays very differently from a game of 10. We've collected recommended starting setups for every group size in a separate guide.
Safe categories to start with
For the first rounds pick universal categories everyone knows, no specialist knowledge and no sensitive topics:
- Food, Animals, Travel, easy and universal.
- Home, Everyday Objects, Nature, good for mixed groups.
- Movies & Series, Sport, Music, when the group shares interests.
