Team size in this game varies for different levels. For senior level, the team size is seven, as decided by FINA. Here six players will be field players and one will be the goal keeper. In 2014, FINA reduced the number of players from 7 to 6 for the U20 and junior level tournaments. This implies that there will be 5 field players and one goalkeeper.
FINA has decided to extend the six number of players rule to all levels after the 2016 Olympic games. If a team commits any major foul, then the referee may direct the team to play with 6 players instead of 7 for 4 minutes. If the foul is much severe like striking a player, then he/she may be even disqualified from playing any future tournaments.
