Most tricks require you to throw a sleeper, so you need to know this.
1.Start your position as shown.
2.Throw the yo-yo down, turning your hand over. When the yo-yo is at the end if the string, let it spin, don't pull it back, when you do want it back, give a slight tug. If you have trouble at first, throw it at about a 45 degree angle in front of you.
3.Catch the yo-yo and you are done.
