The completion of sequences or sets that would be impossible to form without jokers & wild cards is one useful tactic for using them. A joker can be used to finish a sequence, for instance, if you have two cagame downloadingrds in a row of the same suit but one is missing in the middle. Likewise, a wild card can be substituted to form a set if you have three cards with the same rank but different suits. Knowing when to use and hold onto jokers & wild cards is a crucial part of using them. Jokers and wild cards can add significant value to your hand, so in some situations it can make sense to hold onto them for as long as possible.
