Casus: Imposter Spy Party Game
Pass One Phone, Spot the Liar
Free · In‑App Purchases · Designed for iPad
The imposter party game for one phone: 3+ players, no internet, no setup. Pass the phone, get your secret word and find the spy before time runs out!
One of you is the imposter. Everyone gets the secret word except the spy. Ask questions, drop hints, call out the shady answers and catch the spy before the timer runs out!
Casus is a pass-and-play imposter party game for 3 or more players. One phone, no internet, no accounts: add the players, pick your categories and pass the phone around. Perfect for game nights, family evenings, road trips and parties.
HOW TO PLAY
• Pass the phone. A handoff screen shows whose turn it is; each player flips their 3D card in private and sees the secret word, or finds out they're the spy.
• Start the timer. Take turns asking questions and giving hints without giving the word away.
• Vote. Catch the spy and the innocents win. But if the caught spy names the word in a last guess, the spy still wins!
ROLES
• Spy: doesn't know the word and has to bluff their way through.
• Innocent: knows the word and hunts for the spy.
• Detective: starts out knowing one player they can trust.
• Faker: doesn't know the word and wins alone by getting the most votes as the spy.
• Accomplice: knows the word and the spy, and covers for them.
• Forgetful: an innocent who forgot the word and has to follow everyone's hints.
HIDDEN SPY MODE
The spy doesn't know they're the spy. They get a word like everyone else, only it's a decoy, and they have to work it out from the hints.
