You play as long as you have booked the court and count the number of games won. The match can end in a tie.
You play for as long as the court is booked and count the games won by each side. There is no fixed number of games and no sets: every game counts the same, from the first to the last.
Scoring
Play games the normal way for your sport. When the booked time is up, finish the game you are in and stop. The side with the most games wins. An equal number of games is a tie, which is a valid result.
Entering the result
Enter the total games won by each side, for example 7-5 or 6-6. Set scores are not needed.
