One crucial ability that can affect how a game turns out in Rummy Pro is knowing when to fold and when to hold onto specific cards. It might initiallyhi games seem beneficial to hold onto valuable cards, but if they don't help form melds or run the risk of being discarded by an opponent, it might be better to let them go. If you want to make wise choices throughout the game, you must evaluate each card's possible worth in light of your overall strategy.
