A competitive game of table tennis is played to the best of five or seven games. The first player to get to 11 points in a game is the winner. However, if a game is tied at 10-10, a player must win a game by two clear points. You do not lose service if you lose a point - each player must serve for two points in a row before handing the service over to their opponent.
For every table tennis competition, a referee is appointed with a deputy who can act on their behalf. The referee is required to be present at the venue throughout a tournament and is required to uphold the rules.
During a table tennis match, an umpire is appointed to decide on the result of each point or rally. The umpire is required to use their judgement when applying the laws and regulations of the ITTF. Where the umpire is officiating alone, their decision is final and they should be seated about 2–3 metres from the side of the table and in line with the net.
