* Thunder Serve : Hold the Up/Left Diagonal before pressing the serve button, and before hitting the ball hold the Down/Left Diagonal when the ball becomes red and press the button. This serve does an ace any time except in the last two games, but you can also do it. You must press the button a bit before the ball becomes red, and you'll make an ace on the last line on the ground. The ball looks like a missile shot from the air.

* Phantom Serve : Hold the Up/Right Diagonal before pressing the serve button, and before hitting the ball hold the Down/Right Diagonal and when the ball becomes red press the button. This serve does an ace always except with the last two games. The ball splits in three phantom balls.

* Towering Serve : Hold Up before serving and hit the ball a bit before the ball becomes red. The ball leaves the screen and you don't know where it falls down.
