The goal of each side
The imposter game is a hidden-role social deduction game with exactly two sides and two win conditions. Everyone shares one secret word except a hidden imposter who does not have it. From there the rules reduce to a single question each round: can the group identify and vote out the imposter?
- Civilians win if the group votes out an imposter.
- The imposter wins by surviving the vote — either because an innocent player is voted out, or because the vote ties and nobody is eliminated.
Note what is not a rule: the imposter never has to guess the secret word to win, and civilians never have to prove the word — they only have to catch the imposter at the vote.
The roles
There are only two roles, and every player is dealt one secretly at the start of a round.
- Civilian. Knows the secret word. Gives honest, related clues that prove they know it — but subtle enough not to hand the word to the imposter. Every non-imposter is a civilian.
- Imposter. Does not know the word (single-word mode) or holds a close look-alike (word-pair mode). Must bluff a clue that fits the conversation and blend in. In a multi-imposter game, imposters do not know each other.
Setup rules: players and imposters
Two numbers define a round before any words are dealt: how many players, and how many of them are imposters.
- Players. Three is the minimum for a legal round — one imposter and two civilians. Below three there is no group to deceive. This online version supports 3 to 20 players passing a single device.
- Imposters. The classic game uses one. You may set any count from 1 up to players minus one (there must always be at least one civilian). More imposters tilt the game heavily toward the deceivers.
A balanced guideline for imposter count by group size:
- Up to 6 players — 1 imposter.
- 7 to 12 players — 2 imposters.
- 13 or more players — 3 imposters.
These are recommendations, not hard limits — a bigger group with a single imposter simply plays as a longer, harder hunt.
Order of a round
Every round follows the same fixed sequence. This is the structural rule set; the play-by-play version lives on how to play.
- Deal roles. Each player privately learns their word or that they are the imposter. Roles stay secret.
- Clue round. Going in turn order, each player says exactly one word related to the secret word. You may not say the secret word itself.
- Discussion. Players argue about whose clue felt wrong. No new formal clues; the secret word still may not be spoken aloud.
- Vote. Everyone points to or names one suspect.
- Reveal. The most-voted player is flipped. The win is resolved by the conditions above.
Clue rules
- One word per turn. A clue is a single related word, not a sentence or a definition.
- Never say the secret word. Civilians may not state the exact word; by common house rule, saying it forfeits your turn or ends the round.
- No repeats. You cannot reuse a clue another player already gave — this stops players from hiding behind a safe echo.
- Clues must be defensible. A clue that fits nothing is a giveaway; the imposter has to sound like they know the word.
Voting and tie rules
After discussion, every player casts one vote. The player with the most votes is eliminated and their role revealed.
- Most votes is out. Only the top-voted player is eliminated per vote.
- A tie eliminates nobody — which counts as a win for the imposter, because the group failed to catch them. (Popular house rule: run a quick runoff between the tied players instead.)
- Catching any imposter ends it for the civilians. In a multi-imposter game the simplest rule is that voting out even one imposter wins the round for the civilians; a harder variant requires catching them all.
Rule variant: single word vs word pairs
The single biggest rules choice is what the imposter receives. Both are legitimate; pick one before dealing.
- Single word. Civilians share one word; the imposter gets nothing and must infer the topic purely from others’ clues. The purest, most paranoid version.
- Word pairs. The imposter gets a close look-alike — Wolf when civilians have Dog. The imposter can now give clues that almost fit, which is harder to catch and often more fun. Browse pairs on the imposter game words page or roll your own with the imposter game word generator.
Popular variants and house rules
Once the core rules are set, groups love to bolt on twists. None of these are required — agree on them up front.
- Imposter guess. When caught, give the imposter one chance to guess the secret word; a correct guess steals the win.
- Imposter hints. Hand the imposter a vague clue (“a four-legged animal”) so they are not stranded — kind to big groups and beginners.
- Multiple rounds. Play a fixed number of rounds and keep score; the imposter side and civilian side each bank points for their wins.
- Blank / white-card imposter. A variant where the imposter knows they are the imposter but everyone plays it cool — already the default here.
- Silent first clue. Skip discussion on round one and go straight to a vote for a brutal fast game.
- Timed discussion. Cap discussion (60/120/180 seconds) so nobody stalls; when the timer ends, vote immediately.
Frequently asked questions
What are the rules of the imposter game?
Everyone secretly gets the same word except one hidden imposter. Players take turns giving a one-word clue about the word, then discuss and vote. If the group votes out the imposter, the civilians win; if the imposter survives the vote, the imposter wins. That is the whole ruleset — the rest is player counts, imposter counts, and optional variants.
How does the imposter win?
The imposter wins by not being voted out. If the most-voted player is an innocent civilian, or the vote ends in a tie so nobody is eliminated, the imposter escapes and wins the round. The imposter never has to guess the secret word to win — surviving the vote is enough.
What happens if the vote is a tie?
A tie means nobody is eliminated, which counts as a win for the imposter — the group failed to catch them. Some tables add a house rule for a runoff vote between the tied players instead; both are fair, just agree before the round starts.
How many imposters should there be?
Standard rules use one imposter. As a guideline, use one imposter for up to about 6 players, two for 7 to 12, and three for 13 or more. You can set any number from 1 up to one fewer than the player count, but more imposters make it much easier for them to hide.
Can the imposter say the secret word?
No. In the base rules the imposter does not know the word, so they cannot say it, and civilians are not allowed to say the exact secret word in a clue either — a clue that states the word ends the round or forfeits that player's turn, by common house rule. Clues must be related words, not the word itself.
Do the civilians know who the imposter is?
No. Civilians only know the secret word, never who the imposter is — even the imposter does not know which other player might also be an imposter in a multi-imposter game. Working out identities from the clues is the entire challenge.
What is the minimum number of players?
Three: one imposter and two civilians. Rounds are tense and fast with 5 to 8 players and this online version supports 3 to 20 in a single pass-and-play round.
