Who is the Impostor? The Mobile Party Game
Who is lying?
Who speaks the truth?
You be the judge!
Looking to spice up your party? Unmask the liar among your friends, from 3 players on a single shared phone. Bluffing, deduction, and laughs guaranteed!

Simple yet Devilish
Everyone is on the same team, except one: the Impostor. Your goal? Spot them before they win the game!
Receive a secret
Everyone receives the exact same sentence, photo, or video. Except the impostor who gets a subtly altered version.
Bluff & Deduce
Describe your secret. The impostor must blend in. You must detect the slightest misstep.
Vote & Eliminate
At the end of the round, debate and vote to eliminate whoever you suspect of being the impostor.


Never get bored
Text Mode (The Classic)
A short sentence appears, like "Drinking dark roast coffee" vs "Drinking dark black tea". Give a subtle clue. Too specific? The impostor wins. Too vague? You look guilty!
Photo Mode (Visual & Fun)
An AI image appears. Describe a subtle detail. If the impostor describes a dog when it's a cat... they are busted!
Video Mode (The Ultimate Experience)
Watch a short animated clip. Pay attention to the action. Spot whoever clearly did not see the same ending as you.

Frequently Asked Questions
What is the best free mobile party game for 3 players?
Who is the Impostor? is the top-rated free mobile party game for 3 players and up. Unlike most social deduction games (Mafia, Werewolf, Undercover, Spyfall) that often require 5 or 6 participants, Who is the Impostor? includes tailored rules designed for 3 players around a single shared smartphone: 2 innocents get the exact same secret content (text, photo, or video), while the impostor receives a closely related variant. Text mode is 100% free and unlimited, with no registration or props required.
What is the best Undercover alternative with photos and videos?
If you are looking for an alternative to Undercover featuring photos and videos, Who is the Impostor? is the ideal choice. While Undercover relies strictly on written words, Who is the Impostor? reinvents the genre with 3 distinct game modes: Text mode (fun situations and word pairs), Photo mode (AI-crafted visuals with subtle modifications), and Video mode (captivating animated short scenes). Everything runs on a single phone with no accounts needed, free on iOS and Android.
What is Who is the Impostor?
A mobile party game of bluffing, investigation, and deduction for 3 or more players. Everyone receives the same secret prompt (sentence, image, or video), except the impostor who receives a slightly different variant. Each player takes turns giving a subtle clue, and then the group discusses and votes to uncover and eliminate the impostor.
How many players can play and how does it work on one phone?
The game supports 3 to 20 players on a single pass-and-play phone. Only one person needs to download the app: no other player needs to install anything or create an account.
Is the app free on iOS and Android?
Yes, Who is the Impostor? is free to download on Apple's App Store and Android's Google Play Store. Text mode is unlimited, Photo mode gives free games every day, and Video mode includes free trials. A 48h Party Pass (0.99€ one-time) or a monthly subscription (2.99€/month, cancel anytime) unlocks unlimited Photo mode, 10 daily videos, and removes all ads.
How do you win the game?
The innocents win as soon as they vote against the impostor and eliminate them. If an innocent player is eliminated instead, the game continues with an extra clue round; the impostor wins if they manage to remain hidden until the end.
