The ultimate party game! Find the spy among your friends. Easy to learn, impossible to put down.
SUS is a social deduction party game (imposter game) where 3 to 20 players share a single phone, take turns viewing a secret word, and try to figure out who the imposter is. Pass the phone around, give clever clues about your word, and vote to eliminate the spy — all without needing internet, accounts, or a second device.
Most party games either need everyone to download an app, require WiFi, or take ten minutes to explain. SUS gets your group playing in under 30 seconds. Everyone swipes up to see their secret word card — civilians all see the same word, while the imposter gets a different one (or no word at all). The discussion phase is where the game comes alive: bluffing, reading faces, and trying to figure out who doesn't belong.
## How Do You Play SUS?
Each round, players take turns privately viewing their word card by swiping up on the phone. Civilians all receive the same secret word and must give subtle clues that prove they know it — without making it obvious to the imposter. The imposter sees a different word and has to bluff their way through. After the discussion timer runs out, the group votes on who they think the spy is. A built-in animated countdown timer shifts from green to red as time runs low, creating real tension without needing a separate app or stopwatch.
## What Makes the Mr. White Role Special?
The Mr. White role adds a strategic comeback layer that changes how every round plays out. Mr. White is a special imposter who receives no word at all — they're completely in the dark and must piece together clues from the discussion to figure out what word the civilians are hinting at. If the group votes Mr. White out, they get one final chance: guess the secret word correctly and steal the win. This "last guess" mechanic means the game is never truly over until the final moment, and it keeps voted-out players invested in the outcome.
## What Word Packs and Customization Does SUS Offer?
SUS includes 12 themed word packs with over 1,100 words covering Everyday Objects, Food, Video Games, Anime, Celebrities, TV Shows and Movies, Sports, Animals, Music Artists, Gym and Fitness, and fully custom packs you create yourself. Custom word packs let your group play with inside jokes, school subjects, or any theme you want. Game settings are adjustable too — set the number of imposters (up to half the players), choose round durations from 30 seconds to 15 minutes, and toggle an optional hint word that gives imposters a fighting chance.
## Who Is SUS For?
SUS is built for anyone who wants a fast, fun group game with zero setup. Whether you're hosting a party and need something that works for 15 people without making everyone download an app, looking for an in-person social deduction game like Werewolf or Mafia without needing a moderator, killing time on a road trip or camping trip with no cell service, or organizing a family game night that keeps both teenagers and adults engaged — SUS adapts to your group. Choose from pop culture packs like Anime and Music Artists to keep it relevant, or create a custom pack tailored to your crew.
## What Makes SUS Different?
SUS is one of the few native mobile social deduction word games with a dedicated Mr. White role — most alternatives are browser-based or lack this added layer of strategy. The entire game runs on a single phone passed between players, making it the lowest-friction party game to start. It supports 33 languages with localized word packs, and 16 unique illustrated player avatars give each round a personal touch. With zero data collection and fully offline play, nothing stands between your group and the game.
Rated 4.8 stars with over 850 reviews on the App Store. Actively developed with new word packs added regularly.
