Abstract: A cup and ball assembly includes a mounting bracket that has a door slot thereby facilitating the mounting bracket to be positioned on a door in a building. A support arm is coupled to the mounting bracket and the support arm extends downwardly along the door and away from the door when the mounting bracket is positioned on the door. A ring is coupled to the support arm and the ring lies on a horizontal plane when the mounting bracket is positioned on the door. A stub arm is coupled to support arm and an extension arm insertably receives the stub arm for removably attaching the extending arm on the stub arm. A tether is disposed on the extension arm and a ball is coupled to the tether thereby facilitating the ball to be thrown toward the ring by a user to test the user's aim and skill.
