Aim the dart so the tip faces the target and your gaze is in line with the board.
Align your dart with your gaze on a straight line aimed your targeted spot.

Without moving your elbow, slowly pull the dart backwards toward your chin. Make sure to pull back along the straight line you made during setup.

Throw your upper arm forward along the line, and when you reach the position you started in before the pull back, release the dart and let it fly.

Follow-through by releasing your bent wrist as well to allow the dart to fly naturally and straight. It's recommended that your palm be facing the floor when your arm drops.
