The most common configuration for a sports kite is a roughly triangular "delta" shape, with two lines for control. Pulling on the right hand line causes the kite to turn to the right, and so on. Using combinations of pulls and pushes (to give slack to the lines), complex tricks and patterns can be flown.
Many pilots also fly four-line (or "quad-line") kites, which are controlled with a pair of joystick-like handles, each with two lines attached. Skilled use of these handles allows a quad-line kite to achieve tricks that are difficult or impossible with a dual-line kite.
