Answer: In tennis, a set consists of games. The amount of games is based on who can reach 6 games first. If both players reach 5 games each in the set, then a win by two games rule applies. So, sets can go to 7-5 or 5-7. If the number of games reaches 6-6, then a tiebreaker is used to determine the winner of the set.
In Major Tournaments like the US Open, the final set has a win-by-two rule and never has a tiebreaker at 6-6. So, it is possible for the final set of a major tournament to reach a high number of games.
One of the longest matches took place in the 2010 Wimbledon Championships against John Isner and Nicolas Mahut where the final set reached 70-68 in games.
6-0 Set: Also known as a bagel set, one player wins six straight games while the opponent wins zero games.
6-2 Set, 6-3 Set, 6-4 Set: A more common set is when one player wins six games and the opponent wins two, three, or four games. This is because "breaking" someone, winning when not serving, is difficult and usually only happens once or twice per set.
7-5 Set: With this type of set, one player wins seven games and the other player wins five games. Seven games were needed to win this set because once each player has reached five games each the set will be decided with a win by two games rule or a tiebreaker.
7-6 Set: This is the final type of set you will see in a tennis match and happens when both players reach six games each in the set. Since no "breaks" occurred in the set, a tiebreaker is played. The rules of a tiebreaker are different than normal games.
One wrinkle in the amount of games played in a set, however, are tiebreakers and the "win by two" rule. A player cannot win simply by reaching six games first because if that is the case it will give a strong advantage to the player who serves first. If no "breaks" occur, a score of 6-5 will occur, with the player serving first winning the match. That is why, in order to win a set one has to win by two games. If the score is 5-5 or 6-5, another game or two will be played until a score of 7-5 is achieved.
If the score ends up 6-6, different rules apply in different major tennis tournaments but the most common rule is a "tiebreak." This added set is played, not on a "love, fifteen, deuce" scale but on a numerical scale to seven, also win by two points. The player set to serve first serves then the other player serves twice and back to the first player to serve twice as well. The scores go up until one player has gotten at least seven points and has won by two more than their opponent. Common tiebreaker scores are 7-5, 8-6, 7-4 etc.
The amount of sets played is different for men and women, men play until someone has won three sets while women play until two. A score in which one player has dominated a match, for instance, would be 6-2,6-2,6-3. In this case, the winning player won six games in all three sets and the losing player only won seven games throughout the three set match.
