Players and equipment are arranged as shown.
Two teams are identified by different colours.
Both teams have four wall players on the sides of the field. Wall players' positions aren't constant, they change with the players who pass the ball to them.
Of course the game can be played with other number of players, but care for the size of the area.

Team in possession:
Players must possess the ball with fast combination play. When they change the sides they try to manage it with fast, short passes, deep passes instead of long balls. They take advantage of the outnumbering situations (wall players). After losing the ball, they must try to regain it immediately.
Defensive play: Pressing the player in possession, supporting, shifting toward the ball, closing in the opponent. Defending in good cooperation and agressively.
