A set consists of a sequence of games played with service alternating between games, ending when the count of games won meets certain criteria. Typically, a player wins a set by winning at least six games and at least two games more than the opponent. If one player has won six games and the opponent five, an additional game is played. If the leading player wins that game, the player wins the set 7–5. If the trailing player wins the game (tying the set 6–6) a tie-break is played. A tie-break, played under a separate set of rules, allows one player to win one more game and thus the set, to give a final set score of 7–6. A "love" set means that the loser of the set won zero games, colloquially termed a 'jam donut' in the USA.[55] In tournament play, the chair umpire announces the winner of the set and the overall score. The final score in sets is always read with the winning player's score first, e.g. "6–2, 4–6, 6–0, 7–5".

The alternation of service between games continues throughout the match without regard to sets, but the ends are changed after each odd game within a set (including the last game). If, for example, the second set of a match ends with the score at 6–3, 1–6, the ends are changed as the last game played was the 7th (odd) game of the set and in spite of it being the 16th (even) game of the match. Even when a set ends with an odd game, ends are again changed after the first game of the following set. A tiebreaker game is treated as a single game for the purposes of this alternation. Since tiebreakers always result in a score of 7–6, there is always a court change after the tiebreaker.
Hard courts are made of uniform rigid material, often covered with an acrylic surface layer[7] to offer greater consistency of bounce than other outdoor surfaces.[8] Hard courts can vary in speed, though they are faster than clay but not as fast as grass courts. The quantity of sand added to the paint can greatly affect the rate at which the ball slows down.[9]

Play all your practice games in sets. Tennis is played in sets--you don’t just play one game and then go home! Sets consist of at least six games. The set doesn’t end until one player wins six games and has a margin of two wins over their opponent. For example, if one player has won six games and the other has won five, they’ll have to keep playing until the winner has two more wins than the loser.[6]
Tournaments are often organized by gender and number of players. Common tournament configurations include men's singles, women's singles, and doubles, where two players play on each side of the net. Tournaments may be organized for specific age groups, with upper age limits for youth and lower age limits for senior players. Example of this include the Orange Bowl and Les Petits As junior tournaments. There are also tournaments for players with disabilities, such as wheelchair tennis and deaf tennis.[81] In the four Grand Slam tournaments, the singles draws are limited to 128 players for each gender.
3. They often take only private lessons and play points when they play on their own – which means that they do not have enough repetitions in situations without pressure where they could automate their technique. In other words, they don’t practice enough – they only get more information in private lessons and do not groove the strokes in practice.

It wasn't until the 16th century that rackets came into use, and the game began to be called "tennis", from the French term tenez, which can be translated as "hold!", "receive!" or "take!", an interjection used as a call from the server to his opponent.[6] It was popular in England and France, although the game was only played indoors where the ball could be hit off the wall. Henry VIII of England was a big fan of this game, which is now known as real tennis.[7] During the 18th and early 19th centuries, as real tennis declined, new racket sports emerged in England.[8]
