Goal
Be the first to get rid of all your cards. The whole deck is dealt out; on your turn you must ditch cards into the center pile — but you have to lie about them if you don't have the right rank.
Your Turn
- The required rank climbs each turn: A, 2, 3, … K, then back to A.
- Place 1–4 cards face-down and claim they are that rank — e.g. "two Kings".
- They don't have to actually be that rank. If you don't hold it, you must bluff.
Calling Bullshit
- After any play, anyone else can hit BULLSHIT! during the challenge window.
- The played cards are revealed. If it was a lie, the player who played picks up the entire pile. If it wasn't, the challenger picks it all up.
- Only the most recent play can be challenged, and only those cards are revealed.
Turn order and the required rank always advance by one, no matter who challenges or who eats the pile. You can't call Bullshit on your own play.
Winning
Play your last card and survive the challenge window and you win. But beware — if you're caught bluffing on your final play, you scoop the whole pile and you're right back in it.
