One typical error is to hold onto high-value cards for an extended period of time. If this happens, another player may declare "Rummy," which coulcolor rummyd result in a higher score. To reduce the number of points in your hand, it's critical to form sets and runs as soon as feasible. Discarding valuable cards too early in the game can also be a mistake as it can give other players an advantage if they use those cards for their own sets & runs.
