XBall - A newer format first played at the International Amateur Open in 2002, XBall pits two teams against each other in multiple rounds of Center Flag played one after another until game time runs out. A team scores one point for each game of centerflag they win, and the team with the most points at the end of the match wins. Professional XBall matches are 50 minutes long, split into two halves, while non-professional matches use various shorter game times. Although only 5 players per team play in any given game, depending on league rules, teams may roster up to 19 players and substitute them after each point. Unlike most tournament formats that forbid players to communicate with people on the sidelines, XBall teams have a coach who can communicate, along with the spectators, with players on the field. Players who receive penalties are not permanently removed from the game, but placed in a hockey-like penalty box for several minutes. The National XBall League, a professional circuit associated with Paintball Sports Promotions, plays the XBall format, which was also used for the Smart Parts World Paintball Championships broadcast on ESPN2 in the fall of 2006.
