Instructions
Hold the Wii remote in your hand. When it is your turn to serve, flick your wrist up. This will release the ball.
Watch the Wii Tennis ball go up into the air. Let it fall. Do this step three to four times. Note the amount of time that the ball is in the air.
Hit the Wii Tennis ball. The ball must be at the top of the serve. Wait approximately one and a half seconds; if you swing too late or early, you will make a regular serve. Swing your arm back as in an over-the-shoulder throw. Flick your wrist when you want to make contact with the tennis ball.
