Beat the Flower and Bannana Cup...At 100 and 150cc stick to the bikes that handle better until you get good enough to drive the bigger cars. Stick to he same bike as well to get better. There are short cut at every race but many work only if you have a mushroom to use while in the short cut. My 5 year old girls has all gold at 50/100/150 and Mirror Levels.
I really like this game, and I must say that playing online is a lot better than single player. I also love the courses- Rainbow Road is one of my favorite ones. The battle games are pretty fun too, but why in the world would you want to tie a balloon- three of them at that- on the back of a kart, and then zip around popping them? It isn't that fun... Either way, this is certainly my favorite. But what is wrong with wheelies? Every single time I try to stop a wheelie, I can't get it to, and I run into the darn walls!
