Why in dominoes when I play my last one sometimes the opponent gets the score?

Can you ask that question of someone who is there with you who can see what you are doing and how the play is going? There must be something you are missing. See if you can find someone there where you are who can help you figure it out. You haven't really given enough information for anyone here to understand exactly what is happening. I hope you get it sorted.Why in dominoes when I play my last one sometimes the opponent gets the score?
