21
(Half Court)21 Is a game in which 3 players(or more) participate(free for all). The goal is, by 2s and 3s as well as free throws, to reach 21. When you score a 2 or 3, you shoot free throws. If you make one, you get another, but if not, it's anyone's rebound. If you make 3 free throw in a row, you get the ball back. There are no out-of-bounds as well.First one to 21 wins!(Everything else functions like a normal 5 on 5, where a missed shot is up for grabs...)

5 on 5
Five on five is simply a regular game using 10 players and a full court. One team starts with the ball and drives from one hoop to the other. They pass and attempt to shoot. Then they rebound and whoever gets the ball repeats the process, either going the opposite way(other team) or the same way(team who just shot).
