GrassGames

Thanks so much for the answer.
It was not really important---I just like to "know" why/how !!!!

I am new to Hearts and have played several computer versions.
I love GrassGames.
I have a question---sometimes toward the end of the game---the message comes up "Sally takes remainder of tricks"--None of the games I have played does this. How it is decided who takes the remainder of the tricks?
