In many sports, sending the ball or puck into the opponent`s goal structure or area is the only method of penalty shootout, and the final result is therefore expressed in the total number of goals scored by each team. In other sports, a goal can be one of many scoring methods and may therefore be worth a set number of points different from the others. In sport, a goal can relate either to a penalty shootout instance or to the physical structure or area where an attacking team must send the ball or puck to score points. The structure of a goal varies from sport to sport, and one is placed on or near each end of the field to allow each team to defend. For many sports, each door structure usually consists of two vertical posts, called door posts, which carry a horizontal crossbar. A goal line marked on the playing surface between the goal posts delimits the goal area. The goal is to send the ball or puck between the doorstep, under or through the crossbar (depending on the sport) and above the goal line. Other sports may have other types of structures or areas through which the ball or puck must pass, such as the basketball hoop. .
