Deal all cards evenly to all players
Choose a starting player
The starting player places one or more cards face down and announces their rank
The announced rank must follow the required order, usually starting with Aces and moving upward
Each next player does the same in turn, placing face-down cards and announcing the next rank in sequence
A player may lie about the cards they placed
Any player may call “Bullshit” if they think the previous player lied
If challenged, the previous player reveals the cards they played
If the claim was false, the liar takes the entire discard pile
If the claim was true, the challenger takes the entire discard pile
After a challenge, the next round continues with the rank that follows the last announced rank
A player wins by getting rid of all their cards first
Continue until one player has no cards left
