Royal Raceway

(1) You've got to aim straight when on this ramp or you'll end up hitting one of the mountains.

(2) This is an excellent place to use a lightning bolt, because it'll slow down the other karts and they won't be able to make the jump to the other side.

(3) SUPER SHORTCUT!! After the second turn, there will be a river that runs by the track. Aim for the dark spot on the other side and use a turbo mushroom to get a boost. Once at the edge, jump. You should hit the wall dead on and when the cloud comes to pick you up, he'll put you down on the ramp with the turbos on it. You'll be way ahead of everyone!
