Who's Lying?

Who's SUS? is a social deduction party game on Roblox developed by Bored In Orbit, built around a word-guessing mechanic that blends charades with Among Us-style impostor detection. With 165 million visits and 300K+ favorites since launching in March 2024, it is one of the most-played social deduction games on the platform. The game was previously called Who's Lying? before being renamed to capitalize on Among Us vocabulary still circulating in the Roblox community.

Each round, players split into two roles. Investigators receive a secret word and must describe it in short phrases - specific enough to signal real knowledge to fellow Investigators but not so obvious that the Impostor can mimic the language. The Impostor receives no word at all and must fabricate a convincing description. After all descriptions are submitted, Investigators vote on who they think is bluffing. A correct vote rewards the Investigators; surviving detection as the Impostor wins that role its points:

• 🎭 Investigator role - receive the secret word, describe it without saying it, vote out the bluffer
• 🏆 Impostor role - no word given, invent a plausible description, avoid being voted out
• 💎 Role mastery badges - Professional Impostor and Certified Investigator track performance
• 💰 Cosmetic ecosystem - character morphs, themed chairs, emotes, and chat effects in the shop

Coins are the in-game currency earned from playing rounds, with bonuses for winning as the Investigator who correctly identifies the Impostor or for successfully bluffing as the Impostor. Coins are spent on cosmetics: character accessories, Among Us morphs, themed chairs (Sci-Fi, Toilet, UFO, Volcano), and chat effects. The x3 Coins gamepass permanently triples all Coin earnings, and the 2x Coins Boost from codes doubles earnings temporarily.

Who's SUS? occupies a unique lane in the Roblox party game space - it rewards social intelligence and description craft rather than reflexes or combat skill. With an unusually high ratio of active to expired codes, the developer clearly maintains codes as a long-term engagement tool rather than rotating them quickly.
