Instructions
Play the Power Throws training game until you reach the last frame, where you need to knock down all 91 pins.
Move your character all the way to the right (or left if you are left-handed) and then change your angle to throw into the railing.
Throw your ball as straight as possible along the top of the railing. Flatten out your hand and face the exact center of the sensor bar. Place the WiiMote on your flat hand but don't grip it more than necessary. Throw the ball with your hand flat and your shoulder squared to the TV.
Watch the ball roll along the railing and all the pins will drop with a loud bang.
