Imposterium features for the perfect impostor party game
Imposterium packs everything you need for a great social deduction game into one free, no-install page. Play online or around a single phone, generate your own AI categories, track scores across rounds and switch between 10 languages without ever leaving your browser. The whole game is built to get a group laughing within a minute of opening it, whether you're three friends or a full party of twelve. Here is exactly what's inside this word impostor game.
Play online with invite link and QR code
Create a game and invite friends with a shareable link, a QR code or a short 4 to 8 character join code. Everyone joins from their own phone, so you can play this word impostor game online from anywhere. Hosting takes seconds, and nobody you invite has to install anything or sign up first.
In-person mode on one phone
No second device needed. Pass-and-play mode runs the whole round on a single phone, with players giving clues out loud and voting by voice or show of hands around the table.
AI categories for any topic
Type any theme and the server-side AI writes a custom word list for it, in any of the 10 supported languages. Built-in categories cover everyday themes plus options like Religion and Belief.
Scoring that keeps it competitive
Turn points on to track wins across rounds. The crew scores +2 for catching the impostor, the impostor scores +3 for escaping and +2 for guessing the secret word.
10 languages for words and interface
Imposterium speaks German, English, French, Albanian, Turkish, Spanish, Italian, Portuguese, Dutch and Serbian, for both the interface and the word lists.
Public games and difficulty settings
Make a game public so others can find it in the lobby browser, or keep it private with friends. Choose easy, normal or hard difficulty to match your group, and set the number of impostors to dial the tension up or down.
Free, mobile-first and no account
Every feature is free, with nothing to install and no sign-up to slow you down. Imposterium is mobile-first and runs in any browser, so the same impostor party game works on phones, tablets and computers alike.
