The surface of a pitch is most commonly composed of sod (grass), but may also be artificial turf, sand, clay, gravel, concrete, or other materials.
The term level playing field is also used metaphorically to mean fairness in non-sporting human activities such as business where there are notional winners and losers.
Game courts are usually constructed using a rectangular sub-base made from concrete or asphalt, then covered with an open-grid modular polypropylene (or similar) sports surface to improve safety.
Game courts are typically custom-designed to the interests of the family or organization, and are versatile in enabling a wide variety of sports to be played in a relatively small space.
Game courts for private use will frequently be built with a high fence surrounding the surface to allow for containment of the ball used in play, and, if required, to prevent people from entering.
