Basically, a tennis match is divided into sets. It can be played in best of three or five sets. The vast majority of tournaments take place in best of three sets, but Grand Slam and Davis Cup games feature the longest model.
To win a match, the player must win the majority of sets. If the match is in a best of three sets, for example, the player must win 2 sets. If the match is played in the best of five sets, the player must win 3 sets.
Each set consists of games. To win the set, the tennis player will need to win six games (provided he has at least two games of advantage over his opponent). If players tie at 5/5, a player must win two consecutive games for the set to end (7/5).
If there is still a tie in the set (6/6), a tie-break is played (a game played in best of thirteen points - that is, won by whoever scores seven points first).
