Instructions
Get control of the ball.
Move the ball up the court using the control stick on the Wii Nunchuck, and dribble toward the basket on which your team is shooting.
Get close to the key (the painted area in front of the basket) and hold the "Z" button on the Wii Remote to engage turbo. Using turbo will give your character a speed boost and allow him to dunk more easily. Turbo is limited and you can tell if your player has turbo engaged because their shoes will change color. The colored turbo meter at the top of the screen indicates how much turbo your player has, and it automatically regenerates whenever turbo is not being used.
Perform a dunk by swinging the Wii Remote "Up" and then "Down" in a quick, fluid motion as your player is turbo running toward the basket with the ball. The kind of dunk you do will vary depending on your player's dunking ability and their proximity to the basket.
