Deal all cards evenly to each player
Decide who goes first
The first player places one or more cards face down and says the rank they are claiming
The claim must follow the required order of ranks, usually starting with Aces and moving up
The next player either accepts the claim and plays their turn or calls “Bullcrap” if they think it is false
If “Bullcrap” is called, reveal the played cards
If the claim was false, the player who lied takes the pile
If the claim was true, the player who called “Bullcrap” takes the pile
Continue taking turns in order
A player wins by getting rid of all their cards first
