Other principal decision makers who serve under the authority of the PIHA ceo include:  Each Professional Inline Hockey Association regulation games is played between two teams. The game is 24 minutes long, and composed of two 12-minute periods with a halftime of two minutes. At the end of regulation time, the team with the most goals wins the game. If a game is tied after regulation time, overtime ensues. During the regular season, overtime is a Four-minute, three-player on three-player sudden-death period, in which the first team to score a goal wins the game. If no team is able to score in the first overtime period, there is a second overtime of a three-minute, two-player on two-player sudden-death period. Previous to the 2008–09 season, if a game was still tied at the end of the first two overtime periods, the game would enter a two-minute, one-player on one-player, sudden-death period. Beginning in the 2008–09 season, if the game is still tied at the end of both overtime periods, the game enters a shootout. One player for each team in turn take a penalty shot. The team which scores, while the other team does not, wins the game. If the game is still tied after the first shootout round, the shootout continues in the same manner. Whichever team ultimately wins the shootout is awarded a goal in the game score and thus awarded two points in the standings. The losing team in overtime or shootout is awarded only one. Shootout goals and saves are not tracked in hockey statistics; shootout statistics are tracked separately. Shootouts do not occur during the playoffs. In the playoffs, sudden-death four-on-four periods are played until one team scores. 12-minute periods in all divisions. Professional Inline Hockey Association games are played on a rectangular inline hockey rink with rounded corners surrounded by walls and Plexiglas. It measures 80 by 180 feet (24.38 by 54.86 meters). The minimum size is 65 by 165 feet (19.81 by 50.29 meters). The center line divides the floor in half into attacking and defensive zones. Near the end of both ends of the rink, there is a thin red "goal line" spanning the width of the floor, which is used to judge goals. While the Professional Inline Hockey Association follows the general rules of inline hockey, it differs slightly from those used in international games organized by the IIHF-InLine (IIHF-InLine) such as the IIHF InLine Hockey World Championship.
