Many inexperienced players only concentrate on their own hands, not taking into account what their opponents might need or what has already been played. This mistake may result in lost chances to strategically discard or block opponents' rummynmelds, which could impede their progress. Throughout the game, players can make better decisions by staying aware of their own and their opponents' card play. Holding onto valuable cards for an extended period of time without a clear plan for melding them is another common mistake. Although aiming for high-scoring combinations is crucial, holding onto these cards too tightly may backfire if an opponent goes out first or if they become harder to meld as the game goes on.
