Luigi Circuit is a beginner's track in Mario Kart Wii. You just turn right a couple of times, then you will find a big turn. If you go outside, you will end up getting a million speed boosts.
Just before the final right turn, there is a small left turn. Just before that, there is a ramp to the left. Use a mushroom boost to go through the sand surrounding it and off the ramp.
After that, if you don't take the shortcut above, to your right is a major corner cut through the final turn. Use a mushroom boost to go through and cross the finish line.
