Say, 'What am I again?' and look confused as you look through your cards before you put them down. Let's say it's your turn to put down queens, and you happen to have two of them. 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 may not actually have the cards that you need to put down - the fun is in faking it.
When it's your turn and you put down your cards, you have to say, 'One ace,' 'two twos,' or 'three kings,' and so on. For example, if the first player put down one or more aces, the next player should put down one or more twos, the third should put down three or more twos, and so on. Continue putting down the cards clockwise in consecutive ascending order.
