Frequently Asked Questions

The Impostor is a free online social deduction party game. Everyone receives a secret word except one player — the Impostor — who must bluff their way through the round. Players give clues, discuss, and vote to find the Impostor before time runs out.

The Impostor was created by Guifré Ballester, an independent developer who built it as a free party game anyone can play right in their browser — no app, no account, no sign-up. It is inspired by classic social deduction games like Spyfall, Werewolf, and Mafia, with a unique word-based twist. You can read the full story on the About page.

Yes, 100% free with no hidden purchases or premium features. The game is supported by non-intrusive ads. All game modes, themes, and word packs are available to everyone at no cost.

Yes! The Impostor shares a similar concept with Spyfall — one player does not know the secret information and must bluff. However, The Impostor uses word pairs instead of locations, offers three game modes (Classic, Mysterious, Chaotic), and is completely free to play in your browser with no app required.

Both are social deduction games, but Among Us is a digital multiplayer game where impostors sabotage a spaceship. The Impostor is an in-person party game where everyone is in the same room passing a phone. It is the right pick for game nights with the people physically next to you, not online matches with strangers.

The Impostor supports 3 to 20 players. The game works best with 4 to 10 players. For larger groups (10+), we recommend using 2-3 Impostors to keep the game balanced.

For groups of 6, The Impostor sits in the sweet spot: one Impostor versus five Citizens leaves enough room for misdirection while keeping every player involved in the discussion. Rounds run about 5 to 7 minutes, so you can play many in an evening.

A typical round takes 5 to 10 minutes including setup, word reveal, discussion, and voting. The round timer is adjustable from 1 to 15 minutes. Quick rounds with small groups can be done in under 3 minutes.

There are three modes: Classic (the Impostor has no word and must bluff entirely), Mysterious (the Impostor gets a different but related word from the same category), and Chaotic (the number of Impostors is randomly assigned each round, creating maximum paranoia).

Absolutely! The game is family-friendly and suitable for ages 8 and up. The Animals and Nature themes work especially well for younger players. Choose Classic mode for the simplest experience.

No, The Impostor is designed exclusively for in-person play. Players pass a single device around to view their secret roles privately, so everyone needs to be in the same room. This is what makes it a great party game!

No. The Impostor works directly in any modern web browser (Chrome, Safari, Firefox, Edge) on phones, tablets, and computers. No download or installation required — just open the website and start playing.

Yes. The Impostor is built to be a party game that runs in any browser with no app needed — no install, no account, no setup. Just open theimpostor.app on one phone, and the whole group plays from that single device.

Any device with a modern web browser works: iPhones, Android phones, iPads, tablets, laptops, and desktop computers. The game is optimized for mobile since it is designed to be passed around.

You need to load the site once with an internet connection. After that, The Impostor works offline — it is an installable app (PWA), so you can add it to your home screen and play with no connection. Everything runs on the single device you pass around.

No — The Impostor has no accounts and no login at all. The whole game runs on the single device you are playing on, with no backend or servers. Your recent players and game settings are remembered locally in that browser, so they are ready the next time you play.

There are 11 themed word packs: Animals, Anime, Brands, Cinema, Food, Memes, Music, Nature, Sports, Tech, and Travel. Each theme contains over 100 word pairs. You can also select 'All Themes' to combine all 1,300+ word pairs for maximum variety.

Each word pair consists of a Citizen word and an Impostor word. These are related terms from the same category — close enough to create confusion but different enough that careful players can spot the Impostor. For example, 'Dog' (Citizen) and 'Wolf' (Impostor) in the Animals theme.

Custom word packs are not currently available but are planned for a future update. For now, the 11 built-in themes with 1,300+ word pairs provide extensive variety for many game sessions.

Yes. The Impostor works well in classrooms of 5 to 20 students because the game runs in any browser without an account, and the Animals or Nature themes keep the vocabulary age-appropriate. Many teachers run 3 to 5 minute rounds between lessons or as a warm-up activity to get quieter students talking.

Yes. The Impostor is a popular icebreaker for office teams of 4 to 15 people because rounds finish in under 10 minutes and the discussion phase gets every team member talking. Many teams play one round at the start of a meeting or during an in-person social hour.

Yes, as long as everyone is in the same car, train compartment, or hotel room. Since only one device is needed, a single phone is enough (no Wi-Fi or data after the initial page load). Rounds last 5 to 10 minutes, which fits the natural pacing of a road trip.

Yes. The role reveal is shown as a single clear word with optional swipe-to-reveal protection. The discussion phase is verbal, so reading speed does not affect gameplay. For mixed-age groups, choose Classic mode and start with the Animals or Nature themes, which use common vocabulary.

The Impostor works especially well as an icebreaker for guests who just met. Because every player has to give a clue, everyone speaks at least once per round. The shared goal of finding the liar creates instant collaboration, and rounds are short enough that nobody gets stuck if they feel awkward.

Many groups treat The Impostor as a casual party game alongside drinks. The discussion phase encourages talking and joking. House rules sometimes add a drink penalty for being caught as the Impostor, but the base game is family-friendly and the drinking layer is entirely optional.

As the Impostor, listen carefully to other players' clues to identify the category and word. Give clues that sound plausible but are vague enough not to expose your ignorance. Avoid going first, as you will have less information. In Classic mode, you can also win by correctly guessing the secret word.

As a Citizen, give clues that prove you know the word without making it too obvious for the Impostor to guess. Watch for players who give vague, generic, or slightly off-topic clues. Discuss with your group before voting — collaboration is key to catching the Impostor.

A good clue is specific enough to show you know the word but vague enough that the Impostor cannot guess it. For example, if the word is 'penguin,' saying 'bird' is too broad, but 'tuxedo pattern' is clever. Avoid one-word clues that could apply to many different things.

If you like Among Us but want something to play with people in the same room, the strongest options are The Impostor, Spyfall, Werewolf, and Mafia. The Impostor is the easiest to start: no cards, no moderator, and no app — just pass a phone.
