This guide describes rules and mechanics actually available in the Blefuj game.
This page is for the moment when you already know how to play, but not what to play tonight. We compare all three modes criterion by criterion, strengths, limitations and a complete example round of each, so you can choose deliberately rather than at random.
The big comparison table
| Criterion | Impostor | Duo | Mind Leak |
|---|---|---|---|
| Players | 3–10 | exactly 2 | exactly 2 |
| Round length | 3–6 min (grows with the group) | 2–3 min | 5–8 min (5 scenarios) |
| Difficulty | medium | low | medium |
| Bluffing level | high (one player fakes it) | low (nobody bluffs) | very high (constant role-play) |
| Deduction level | high, as a group | medium, shared | high, solo |
| Pace | medium, with debate pauses | very fast | calm, narrative |
| Privacy at reveal | each player privately, phone passed around | two private peeks | only the Secret holder sees the secret |
| Best occasion | house party, gathering, icebreaker | travel, queues, breaks | a date, a night in for two |
| Entry barrier | medium, roles need explaining | minimal | medium, needs getting into character |
Impostor: who it's for, strengths, limitations
Who it's for: groups of 3–10 who enjoy shared debate, accusations and laughing at failed bluffs. It's the only mode where everyone plays at once.
- Strength: scales from an intimate three to a full table.
- Strength: the pre-vote debate pulls in even the shy players.
- Strength: variants (two impostors, timers, last chance) keep it fresh for a long time.
- Limitation: with 8+ players rounds drag without a timer.
- Limitation: needs at least 3 people, it doesn't work for two.
- Limitation: a very timid impostor can freeze a round.
A complete example round (5 players): the group picks Places; the civilians' word is “swimming pool”. Clues: Ola, “chlorine”, Bartek, “swim cap”, Kasia (the impostor), “in summer” (safe, it fits everywhere), Michał, “lane four”, Ania, “diving in headfirst”. In the debate Michał points out “in summer” also fits a lake or ice cream; Kasia argues she meant holidays. The vote goes 3:2 against Kasia, civilians win, and Kasia admits that after “chlorine” she'd nearly worked out the word and would risk a specific clue next time.
Duo: who it's for, strengths, limitations
Who it's for: two people who want to play instantly and lightly, travelling, queueing, over coffee. Duo has no roles and no bluffing: you both give honest clues and jointly guess whether you had the same word.
- Strength: zero entry barrier, the rules fit in one sentence.
- Strength: the shortest round of any mode.
- Strength: nobody loses “against” anyone, the result is shared.
- Limitation: less tension than the bluffing modes.
- Limitation: many rounds in a row get predictable, it works best in short bursts.
A complete example round: Marta sees her word, Paweł sees his. Marta: “sweet”. Paweł: “served warm”. Marta: “with fruit”. Paweł: “Sunday breakfast”. Both feel it's a match and guess “same word”. The result: Marta had “pancakes”, Paweł had “waffles”. The trap was that all four clues fit both words, only “crispy” or “from a frying pan” would have separated them.
Mind Leak: who it's for, strengths, limitations
Who it's for: two people who want something deeper than a quick guessing game, usually couples and close friends. The Secret holder acts out reactions across 5 scenarios as if the secret were true, while the Detective hunts for false notes and finally picks the secret from 3 options.
- Strength: the most conversation and laughter per minute of play.
- Strength: the roles (bluffer vs tracker) are distinct and beg to be swapped.
- Strength: a best-of-5 series builds a natural evening-long rivalry.
- Limitation: it needs getting into character, not everyone enjoys role-play.
- Limitation: rounds are longer and don't suit in-between moments.
- Limitation: strictly for exactly 2 players.
A complete example round: the app picks Ola as the Secret holder. She reads the secret privately and hides the screen. Scenario 1: “Someone suggests cooking together. How do you react?”, Ola answers casually but changes the subject a touch too fast. Detective Tomek probes: “what would you cook?”. The next scenarios stack up small tells: Ola dodges time-related details twice. After the fifth scenario Tomek gets 3 possible secrets, rules one out instantly and decides between the other two based on that earlier rush. He's right, a point for detection, and they swap roles for the rematch.
Choosing by scenario
- You have 10 minutes as a pair → Duo (2–3 full rounds).
- You're planning a night in for two → Mind Leak with a best-of-5 series.
- Guests are just getting to know each other → Impostor with an easy category; shared debate breaks ice faster than small talk.
- The party's already rolling → Impostor with two impostors and a timer.
- Playing with people who hate the spotlight → Duo, or Impostor in a bigger group (attention spreads out).
- You want a couch mode without endless phone-passing → Mind Leak (the phone changes hands only once).
Recommendations by player count
- 2 players: Mind Leak for a longer evening, Duo for quick rounds, Impostor is out.
- 3–4 players: intimate Impostor; every clue carries weight and the deduction is purest.
- 5–7 players: Impostor at its best, full debate without the drag.
- 8–10 players: Impostor with two impostors and a timer; consider splitting into two smaller games if the table is loud.
Recommendations by situation
- A date: Mind Leak, the scenarios keep the conversation going by themselves.
- A train or car journey: Duo, short rounds, zero props.
- A house party: Impostor, the more witnesses to a failed bluff, the better.
- A family gathering: Impostor on easy categories, generations compete as equals.
- A team icebreaker: Impostor with neutral categories and a rotating opener.
Which mode is easiest to start with?
Duo, the rules fit in one sentence and there's no bluffing. For a group of 3+, the simplest sensible pick is Impostor with the impostor hint enabled.
Can you play Impostor with two people?
No, the vote needs at least 3 people. Duo and Mind Leak were built for two and deliver similar tension without a group.
Duo or Mind Leak, which is better for a date?
Mind Leak if you have 20+ minutes: acting out scenarios naturally sparks conversation. Duo works better as a short warm-up before something else.
Can you mix modes in one evening?
Yes, it's the best way to play. A simple arc to start with: Duo as a warm-up, several Impostor rounds in the middle, and Mind Leak for two once most guests have left.
Which mode suits players who hate lying?
Duo, nobody bluffs in it. In Impostor such a player still has full fun as a civilian; the impostor role comes up randomly and rarely.
