Four square is a team sport played among two teams with two players each on a square court divided into four quadrants: A, B, C, and D (usually numbers 3, 4, 2, and 1, respectively, depending on the court.) The square that a player gets to before anyone else immediately becomes their position in the game. The objective of four square is to eliminate players on the opposing team to achieve the highest rank on the court, and this is done by bouncing the ball back and forth between quadrants. A player on one team may bounce the ball to an opponent team's player's square, and tries to bounce the ball in a state that the player on the opposing team can not hit it to another square. The winning team will move up in the ranks, and the team that reaches the highest rank, A (usually number 3 on numbered courts depending on the court), first, wins, with all the losing team's players being eliminated. A player is eliminated when a ball is bounced in a player's quadrant and the player is unable to bounce the ball into another player's quadrant. It is a popular game at elementary schools with little required equipment, almost no setup, and short rounds of play that can be ended at any time.
