If players want to improve their chances of winning at rummy, they should be aware of a few common mistakes. Keeping too many high-value cards without forming sets or runs is a common error. A higher penalty for unplayed cards may resrummy yesult from another player going out, which could result in a high point total. Neglecting to observe the cards that other players are discarding and picking up is another frequent error. Players risk missing important hints about their opponents' hands if they don't pay attention to these actions and don't modify their own tactics appropriately. Another mistake is to discard valuable cards too early in the game without thinking about their potential future utility.
