Games, the competition is divided into two categories, male and female. At other levels, this is a matter for the local organising committees. For example, in the United Kingdom, at the three levels of competition (novice – regional, intermediate – regional (north and south), and elite – national level), teams may be mixed sex. There are three standard positions to play: centre, right wing and left wing. While there is typically no official designation, players often have a position they are best at or prefer, though some players will play any of the three and players are free to change position during a match with no prior announcement (and may do so for tactical reasons). The centre player is the player most responsible for defence. The player typically lines up at the centre orientation mark at the front of the orientation area (the line forward of the goal post), further forward than the wings which helps to avoid collisions between players diving towards the direction of the ball. Other defensive arrangements are possible, but less common. The centre player is the most defensive position simply because the player is able to move both to the left and right to defend, covering a greater proportion of possible attacking shot lines. The centre player may also be the defensive coordinator. The left and right wingers generally line up at the end of the orientation marks from the respective sidelines, at the orientation mark. Their main defensive responsibilities are keeping the ball out of either corner of the goal, though they also defend towards the centre. Typically, the wingers are the main offence because there are some advantages to the angles of shots possible from their positions. This also allows the centre player to reserve their energy for defence, though the centre player may also have an offensive role. Scoring A goal scores one point, and is scored when the ball completely crosses the goal line. The team with the higher score at the end of regulation time is the winner. If regulation results in a tie, two three-minute overtime periods are played, for a golden goal (first goal concludes the game). If no goal is scored during overtime, penalty throws and sudden death penalty throws are taken. Should a goal difference of ten be reached, a mercy is called and the leading team is declared the winner. Game play and etiquette The
