Question: how many games do you need to win a tennis match?
Answer: A set is won by the first side to win 6 games, with a margin of at least 2 games over the other side (e.g. 6–3 or 7–5). If the set is tied at six games each, a tie-break is usually played to decide the set. A match is won when a player or a doubles team has won the majority of the prescribed number of sets.
