Different regional variations can affect gameplay, but Rummy Gold is governed by a set of rules that specify how the game is played. Forming legitimate melds and declaring "Rummy" once every card has been merummy nawablded are usually the fundamental rules. On the other hand, some variants add extra components like jokers, which can act as wild cards, or particular scoring schemes that give more weight to some combinations than others. Jokers can be used to replace any card in a meld in certain variations of Rummy Gold, for example. This adds another level of strategy as players choose when to use these valuable wild cards.
