ImpostrGames is a collection of fast, easy-to-learn social deduction games inspired by classics like Mr. White and Undercover. Open the site on one device, gather your friends or family around, and play through three phases: first, everyone reveals their role (normal player or imposter), then players take turns giving short clues while one or more secret imposters try to blend in without ever seeing the real word, character, team, or item. Finally, the group discusses and votes to find the imposters.
Every game on this page is free to play, runs directly in your browser, and is designed for groups of 3–10 players. No accounts, no downloads, and no complicated setup — just pick a theme, enter player names, and start your first round in seconds. The number of imposters scales with your group: 3–4 players get 1 imposter, 5–7 players get 2 imposters, and 8–10 players get 3 imposters for maximum chaos, tension, and challenge as everyone argues over which clues they can really trust.
One shared device
A phone, tablet, or laptop works as long as everyone can take turns viewing it.
3 to 10 players
Smaller groups feel sharper, while larger groups create more noise and bluffing.
A shared theme
Pick a mode your group actually knows so the clue round feels fair and useful.
Five clean rounds
Most groups find their best rhythm after a short warm-up and a few quick resets.
If this is your first time playing, you can quickly learn the basics and see example rounds in our helpful guides:
Every mode uses the same simple rules, but each one swaps in a different theme and word list so you can match the game to your players.
