Youtube Mario: Mario Kart Wii - Expert Shortcuts

This is a compilation of the more superior shortcuts. It requires a high consistent of patience and aim.

Shortcut difficulty:

1. Mushroom Gorge 7/10 - Get to a certain position like I did on the video, and boost just before you hit the off-road. Now before you go off the edge, quickly press jump while turning left.

2. Toad's Factory 6/10 - Drift slightly to the right before hitting the bump and quickly do a trick. Try not to drift too much or you'll crash into the water.

3. Grumble Volcano 9/10 - Make sure to angle your vehicle until you can see the gap clearly. You need to be careful not to hit the mountain while approaching it. Extremely risky but worth it.

4. GBA Bowser Castle 3 10/10 - The hardest of the bunch. Why? Because it comes down to luck when trying to get into a certain position, and anybody could possibly crash into you. Anyway, the best way to do it is to boost towards the upper-left ramp. Very rewarding if succeeded.

5. N64 Bowser's Castle 5/10 - Make sure to line your vehicle towards the narrow platform. It would be best not to go too far on the right in case you fall into the lava. Easy once mastered.
