If you don’t have any of the required cards, you can skip your turn though, it’s better not to pretend to put down 3 of them – and definitely not four. If you say you’ve put down 3 of a card you don’t have, it’s likely that a player will have at least 2 of the card and will know you’re lying and will call “bullshit!” You can also play dumb. Let’s say it’s your turn to put down queens, and you happen to have two of them. Say, “What am I again?” and look confused as you look through your cards before you put them down. Your goal is to make people believe you when you’re lying, and make them doubt you when you’re telling the truth.
If the cards aren’t what the player said they were and the person who called “bullshit” was right, the lying player takes all the cards from the pile and adds them to their hand. If the cards are what the player said they were and the accuser turns out to be wrong, all of the cards in the pile go into the hand of the accuser. If two or more people call out the player in question and they are wrong, the pile is divided amongst all the accusers.
After one player wins, you can continue playing until there are two or three people left if that’s how you decide to play. If you only have one card left, don’t announce it in advance or let people know that you’re about to win. You can also take the bold strategy – if you only have one card left, you can pretend to count off and say, “Oh, perfect! I only have one three!” Though this is more likely to fail than not, you can have fun trying to trick your teammates.
Feel free to use card decks with cards missing or duplicated. This is a great way to recycle decks not suitable for normal card games.
You can also allow the next player to put down the same card as the player before him or her, or the card below or above that card in rank. This will make it easier for each player to actually put down a card he or she has.
