LEFT/RIGHT ARROW KEYS It's human v machine - can you beat the Novarena 3000 tennis-playing machine? First to 9 points wins. Machine always serves. Your racket swings automatically. Direction of ball depends on how you line up as the ball approaches. The more you angle the ball, the more likely the machine is to miss.
