In order to minimize penalty points, carefully consider whether it's worth declaring "Rummy" or continuing to play if you have formed all of your sets & runs but still have unmatched crummy ginards in your hand. When you strategically choose when to declare "Rummy," you can minimize possible penalties and maximize your score. Combining talent, strategy, and a little bit of luck is necessary to win at Rummy Perfect. Being aware of what other players are discarding can help you make more informed decisions about which cards to use for your own sets & runs.
