Watch the video a bunch of times, then follow the tips.
– Keep your thumb pointing straight out at a 90-degree angle, and pulling back to keep tension on the string.
– Try to hit the string as far out toward the tip of your first finger on your throwing hand as possible. These first two tips together will ensure maximum spread of the strings for the second landing on the string.
– When flipping the yo-yo over your throwing hand it is important that it not go any higher than the tip of your thumb. If the yo-yo goes too high, the string won’t pop off like it’s supposed to.
