Vary space used depending on the size of your group. For groups of 8 to 10 players the area inside the three point line works well.

Each player starts off with a ball and must continually dribble within the designated area while trying to knock away the other players ball. When a player loses control of their ball or goes outside of the designated area they are out of the contest and should step out of the designated area. As the number of remaining players are reduced further restrict the area of play.
