Each player is dealt four cards and must have only four cards in his or her hand at the end of each turn. The remaining cards form a 'pick-up' pile with the top card turned over to form the beginning of a 'put-down' pile. A player selects a card from either of the two piles and discards a card onto the 'put-down' pile. Sir Scrabble and Muddler cards cannot be taken. A Sir Scrabble card can be discarded to take another turn. Conversely, a Muddler card can be discarded so that the next player will have to lose a turn. The 'put-down' pile should be turned over, if all of the cards from the 'pick-up' pile have been used. The winner is one who collects four cards of any of the following: queen, jeweler, baby, librarian, waiter, or zookeeper. - BoardGameGeek
