Manner of Play

The rules and scoring are similar to those of lawn tennis, which derives from real tennis. Although in both sports game scoring is by fifteens, in real tennis 6 games wins a set, even if the opponent has 5 games. A match is typically best of 5 sets.

The 2½ inch (64 mm) diameter balls are handmade and consist of a core made of cork with fabric tape tightly wound around it and is covered with a hand-sewn layer of felt. Until recently the felt was always white, but yellow has been introduced for player safety. They are much less bouncy than a lawn tennis ball, and weigh about 2½ ounces (71 grams). The 27 inch (686 mm) long racquets are made of wood and use very tight strings to cope with the heavy ball. The racquet head is bent slightly to make it easier to strike balls close to the floor or in corners.

A real tennis court (jeu à dedans) is a very substantial building (a larger area than a lawn tennis court, with walls and a ceiling to contain all but the highest lob shots). It is enclosed by walls on all sides, three of which have sloping roofs (known as "penthouses") with various openings, and a buttress (tambour) off which shots may be played. The courts (except at Falkland Palace, a jeu quarré design) share the same basic layout but have slightly different dimensions. The courts are about 110 by 39 feet (33.5 × 11.9 m) including the penthouses, or about 96 by 32 feet (29.3 × 9.8 m) on the playing floor, varying by a foot or two per court. They are doubly asymmetric - not only is one end of the court different in the shape from the other, but the left and right sides of the court are also different.

The service only happens from one end of the court (the "service" end) and the ball has to travel along the penthouse to the left of the server to the other end, called the "hazard" end. There are numerous widely differing styles of service, many with exotic names to distinguish them. The game of stické uses a smaller court of a similar layout.

The game has other complexities, including that when the ball bounces twice at the serving end, the serving player does not generally lose the point outright. Instead a "chase" is called, and the server gets the chance, later in the game currently being played, to replay the point from the other end, but under the obligation of ensuring every shot they play has a second bounce further back from the net than the shot they failed to reach. One result of this feature is that a player can only gain the advantage of serving through skillful play (i.e. gaining a "chase" which ensures a change of end), as opposed to lawn tennis where service alternates between the players by rotation.

Another interesting twist to the game is the various windows below the penthouse roof that, in some cases, offer the player a chance to win the point instantly by hitting the ball into the opening. The largest window, located behind the server, is called the "Dedans" and must often be defended from hard hit shots (called "forces") coming from the receiving (called the "hazard") side of the court. The resulting strategy of long volleys and shots off the side walls and penthouse roof lead to many interesting shots not normally played in lawn tennis. However, because of the weight of the balls, the small racquets, and the need to defend the rear of the court, lawn tennis strategies like serve and volley are rarely employed.

The level of thinking involved makes real tennis unusual in being a physical sport which people often take up and reach a relatively high level of proficiency later in life.
