Divide the group up into two teams

Divide the group up into two teams at each end of your playing area. One person should stand opposite their team ready to catch the ball – they act as the basket.
The game is played with a ball that looks like volleyball, only it has the texture and bounciness of a basketball. It is played five on five, much like basketball, but there are two human goal posts holding baskets. So total, there are six people on each team. Each team has five players on the court and one basket holder. The defensive mindset is the same as basketball, but the rules change a bit when on offense. The person with the ball is not allowed to walk or run with the ball. They can push off with one foot to pass or shoot, but that is all. When shooting, the basket holder can move the basket to catch the ball so long as they do not leave the chair they are standing on. There do not seem to be any fouls in the game. It was basically a free for all. When the ball goes out of bounds it changes possession.
