Mario Kart Wii is a racing game in which you can choose different characters from the Mario franchise to race with. You can pick up different items and use them to your advantage in both offensive and defensive ways. With the Wii, you must physically move yourself to steer your on-screen character. The game has many unlockable characters and items that you must race to obtain. New track maps are available after unlocking new cups. Each new cup you unlock contains four new maps. You must race in a cup, not a single track, to unlock new maps.
Win trophies in the Mushroom and Flower Cups by finishing in third place or better in the overall cup race. This will unlock the Star Cup. Unlocking the Star Cup opens the Daisy Circuit, Koopa Cape, Maple Treeway and Grumble Volcano maps.
Finish in third place or better in the Shell and Banana Cups to unlock the Leaf Cup. Unlocking the Leaf Cup opens DS Desert Hills, GBA Bowser Castle 3, N64 DK's Jungle Parkway and GCN Mario Circuit maps.
Beat the Leaf Cup in third place or better to unlock the Lightning Cup. Unlocking the Lightning cup opens the SNES Mario Circuit 3, DS Peach Gardens, GCN DK Mountain and N64 Bowser's Castle maps.
Complete the Star Cup in third place or better to unlock the Special Cup. Unlocking the Special Cup opens the Dry Dry Ruins, Moonview Highway, Bowser's Castle and Rainbow Road maps.
Win a trophy in all 150cc cups, the hardest mode, to unlock Mirror Class. Mirror Class opens the mirror courses for all maps. Mirror courses are the same maps that you already have, but you race in the opposite direction around the tracks.
Race on the easiest difficulty and you can unlock all the new maps as long as you place in the top three in the cup you're in. Harder difficulties do not affect unlocking new maps. Use protective items to shield yourself from other racers' attacks by dragging them behind you with the "L" button.
Stay on the track. Falling off can mean the difference between first and last place.
