To configure the game score we will go to:
System → Courts → Sports
We will see a window with all the sports that we have, we click on "Edit" of the sport that we want to adjust the score of the games.
In the sports tab we will go to the option "Matches Parameters" from the menu on the left. We will see that in the window on the right we have all the necessary information about matches. From here we can modify the games the way we want, put more punctuation, less ... etc.
