Halep is often described as an aggressive counterpuncher who uses her movement and racquet head speed to turn rallies in her favor.
Her game is not serve-centric; instead, Halep relies on neutralizing points with her return and then moving the ball around the court with deft touches. She has a versatile backhand that she hits with equal confidence both crosscourt and down the line, and her forehand has plenty of topspin that is especially effective on clay.
Halep doesn't approach the net a lot, but can volley competently when the need arises. She also brings out the drop shot and lob every once in a while to keep her opponents guessing.
