Discarding can become a strategic move with this degree of awareness. In Spin Rummy, jokers are wild cards that can greatly improve your gameplay when used strategicrummy lunchally. They are very flexible tools for finishing sets and runs because they can represent any card in a meld. If you have two 8s and a Joker, for example, you can quickly form a valid meld by using the Joker as an 8 of any suit. Jokes must be used sparingly, though, as hoarding them for too long can result in lost opportunities.
