How to play the spy game (imposter word game)
The spy game, also called the imposter game, "who is the spy" or undercover, is a social deduction party game for 3 or more people. Everyone shares a secret word except the spy, who has to blend in. These rules work with paper slips or with any app.

Goal: the innocents want to find the spy; the spy wants to stay hidden or figure out the secret word. A round takes 3 to 15 minutes and needs no board, no cards and no game master.
Setup and round flow
- 1. Choose a secret word. Pick a category everyone knows (animals, foods, places, jobs…) and a word from it. With paper: one person writes the word on every slip except one, which says "SPY", folds them and that person also plays. With an app, the phone picks the word and deals the roles.
- 2. Deal the roles in secret. Every player looks at their slip or card alone. Innocents learn the word, the spy only learns they are the spy. Nobody reacts out loud.
- 3. Start the timer. 5 to 8 minutes works for most groups. Saying the category out loud is allowed (the spy learns it too).
- 4. Ask questions in turns. A player asks anyone a question about the word ("Would you find this at a wedding?"). The person who answers asks the next question. You may not say the word itself.
- 5. Accuse and vote. When time runs out, or when someone calls a vote, everyone points at the player they suspect on the count of three. The player with the most votes is revealed.
- 6. Spy's last guess. If the spy is caught, they get one chance to name the secret word. A correct guess steals the win. If an innocent is voted out, the spy wins.
Scoring
Play several rounds and keep score. A common system:
- Spy not caught: spy +2 points.
- Spy caught but guesses the word: spy +1 point.
- Spy caught and wrong: every innocent +1 point.
- First to 5 points wins the night.
Popular variants
- Multiple spies: with 6 or more players, use 2 spies who don't know each other. Roughly one spy per three players keeps it fair.
- Undercover / hidden spy: the spy gets a similar but different word ("cat" vs. "dog") and doesn't know they're the odd one out.
- One-word clues: instead of questions, each player says one word related to the secret word, going around the circle twice, then everyone votes. This is the version that spread on TikTok as "the imposter game".
- Locations: the secret is a place and every innocent imagines a job there, the idea behind the commercial board game Spyfall.
- Special roles: a Detective who knows one innocent, an Accomplice who knows the spy, a Faker who wants to be voted out.
Tips for innocents
- Ask questions that only someone who knows the word could answer well.
- Avoid answers that are too obvious; the spy is listening and can guess the word.
- Watch for copycat answers and vague replies like "it depends".
- Don't vote too fast; a wrong vote hands the win to the spy.
Tips for the spy
- Listen first; the early answers narrow the word down quickly.
- Give short, confident answers that could fit several words.
- Ask questions that sound specific but stay generic ("Have you used one this week?").
- If you're sure of the word, steer the group toward voting for someone else.
Quick answers
- How many players? At least 3; 4 to 10 is the sweet spot for one spy.
- Is it the same as Mafia or Werewolf? No. There is no moderator, no night phase and no elimination; one round, then reveal.
- Is it good for kids? Yes. Use easy categories like animals or food; kids around 7 and up usually get it after one round.
