Some facts about the rules:
Up to
2001 a table tennis game was played up to 21 points. But in order to make the
game more exciting they reduced the points from 21 to 11.
A game of
tabletennis is now played up to 11 points.The winner is the player or pair who first scores 11 points, unless both players or pairs score 10 points (called deuce). Then a game will be won by the first player or pair to gains a two point lead.
At deuce that´s 10:10, service alternates with each player only having one serve, until one player or pair gains a two point lead.
