There is one thrower and the rest of the team is in a box of cones, size of the box depending on the size of the group. When the disc is in the air each person must decide if they can catch it. If you move for the disc than you HAVE to catch it. Each catch is a point and you need 3 points to become the thrower. If you move or if the disc hits you and do not catch it then you are out. Once you are out you go to the Mac line. From here you can go for a disc after someone in the game moves or you can hit the disc into the box to hit other players. If you mac the disc into someone then you are in and they are out.
