First, inform the dealer or game host about the error so it can be rectified. In many games, proper procedures are in place to handle such occurrences, which may involve reshuffling and redealing the cards. It's essential to remain calm and ensure that the game maintains its integrity and fairness. The resolution typically depends on the specific rules of the game being played, but correcting the mistake as soon as possible is key to keeping the game enjoyable for all participants.
