While managing to make perfect use of the lob and spinning shot aim is essential to play the game, top spins can be more a nuisance than helpful. Since it shares the same button as dives, and a good top spin shot requires additional power control (by either pressing up or down), Sega's 8-direction pads, if broken or dirty, or even simply if the user's finger slipped, top spin shots often ended up turning into a dive, the ball passing uselessly by the helpless player.
