Here is a trick that will increase the odds of making a 3-pointer. As player 1, go to the halfcourt line and hold down the shoot button until your player lets go of the ball. Not only is he making halfcourt shots, but he is making them easier than he would if he was closer to the basket. Play your friend and make them think you are great.
