Each team can field six players at a time on the court, one player being a goalkeeper. But the coach can take the goalkeeper off and switch him with a field player whenever they like. Although it usually only happens in the end to score with one more outfield player. This can make advantages for the attacking side of the team, and disadvantages when it comes to their own defense. The team is also allowed to change players any time in the game; usually, they change the whole team. Individual substitution happens sometimes, but it usually happens when a player is exhausted or is hurt.
