One of the most important cards in a game of rummy, Jokers can fit in anywhere. They help you create impure sequences, and sets. A joker can be used as a substitute to any card. There are two types of jokers in a game of rummy - a printed joker - a card on which 'Joker' is clearly mentioned, and a wildcard joker. Wildcard Joker At the start of each deal, a card is picked randomly as the wildcard joker. This card is kept in an open position at the bottom of the closed deck. For eg. if 5 of hearts is selected to be the wildcard joker, then 5 of all suits will be considered jokers. A wildcard joker can also be used to form a pure sequence if it fits the pure sequence criteria. Printed Joker A card on which it says 'Joker' is a printed joker. A deck of cards has 2 printed jokers. In rummy, you can use it to create impure sequences, and sets. Note: If the printed joker card is selected as a wildcard joker, then all Aces are jokers.
