Staff Ghost Strategies
Figure Eight Circuit- Here, the best tip is to use the ROB BLS kart and use SSMTs like hell. Also, stick close to the inside of the bend and use the mushroom to cut grass on one lap.
Yoshi Falls- Mini-turbo every bend and the final straight. Take the first and third waterfall, and ignore the second, as even with the trick, it will slow you down. Use Egg1 for beating the Staff Ghost, then ROB BLS for a better time.
Cheep Cheep Beach
Mini-turbo every corner and SSMT through the shallow water. Use a mushroom on the second lap going through the ocean. PRB off the second ramp can be helpful.
Luigi's Mansion
First, SSMT on the path. Mini-turbo each corner and cut across the grass outside the tunnel with mini-turbos. Mini-turbo constantly in the mud section. Mushroom best used in the mud section or across the grass outside the tunnel.
Desert Hills
SSMT and Mini-turbo like mad, and cut the last corner with a mushroom. Use the egg1 or perhaps the Yoshi Standard kart.
Delfino Square
Always mini-turbo each corner, and SSMT the first straight. Use either the dock or mud shortcut, and PRB after the drawbridge on laps 1 or 3.
Waluigi Pinball
Other than Mini-turboing the pinball section, boosting on ever corner and getting the best boost, there are no real tips.
Shroom Ridge
Mini-turbo each corner many times and SSMT like crazy. I have found that boosting over the grass doesn't seem to help much though.
DK Pass
Ignore the special item box shortcut, and go around. Mini-turbo like crazy, and use the mushroom on the path to the zipper.
Tick Tock Clock
Avoid all glitches and shortcuts, and boost ever corner. SSMT on the straights, and go over the gears at the end to cut some seconds off your time.
Mario Circuit
Use the normal tactics, and SSMT over the sand near the piranha plants. Use the mushroom over the sand on lap 3.
Airship Fortress
SSMT the first straight, mini-turbo each corner and hop, not drift at the tower part (real recommendation for Players page pros, do not argue with this). Use the mushroom while going past the flame jets on lap 3.
Wario Stadium
Boost ever corner, and avoid going over many of the jumps, as the less time in the air, the better it is for you.
Peach Gardens
Mini-turbo like usual, but SSMT through the flowerbed after the start. Also, snake through the maze to save quite some time.
Bowser Castle
Use the usual, and take the same shortcut the ghost does. SSMT on the rolling log, and use the mushroom on the moving platforms. At the end, hold a power-slide and jump at the gap in the fence to cross the finish line in mid-air and cut some seconds.
Rainbow Road
Use mini-turbos on the spiral. SSMT twice on each straight and hop at the start and end of both the loop and corkscrew. Use a shortcut if you dare, but don't worry if you can't do the tricks.
Mario Circuit 1- You must remember that the ghost only boost on corners and uses the mushroom while going across the sand. Just mini-turbo each corner and boost more times than the ghost does.
Moo Moo Farm- Use the ROB BLS and mini-turbo many times on each corner. Use your mushroom on the last straight, to the very right to save time.
Peach Circuit- Mini-turbo each corner, and use SSMTs and your mushroom to cut various banks of grass.
Luigi Circuit GCN- Mini-turbo many times on each corner, SSMT a lot on the straight. Use PRB if necessay, by holding the mini-turbo over the zipper.
Donut Plains 1- Don't use the fence shortcut and mini-turbo a lot around it. Mini-turbo over the mud patches, and I'm not sure where the best place to use the mushroom is.
Frappe Snowland- Mini-turbo a lot like normal, but boost and jump to cut the second bend for a shortcut. After the snowmen, cut the left bank to save some time.
Bowser Castle 2- Try to jump the jump ramps, and hit every zipper. Mini-turbo a lot around corners and on some straight ways, like the last one.
Baby Park- Mini-turbo the bends, and twice on each straight. Repeat four times.
Koopa Beach 2- Use the ROB BLS, and mini-turbo each corner. Take the left path at the islands with the deep water. Cut across the grass at the end with a mushroom.
Choco Mountain- Mini-turbo each corner. At the end, mini-turbo at the first hill and bounce over the rest to save time.
Luigi Circuit GBA- Cut each corner really closely, and use your mushroom over a grassy bank. Do not hit the puddles.
Mushroom Bridge- SSMT on the bridge, and mini-turbo each corner. Do not take the shortcut over the hill, as it can slow you down.
Choco Island 2- PRB through the gap on lap 1, then SSMT through the mud pool near the end. Avoid the ramps, and use your mushroom through the gap in the fence on the last lap.
Banshee Boardwalk- Mini-turbo each corner, and do one mini-turbo on each straight. Mini-turbo more on the final stretch.
Sky Garden- Mini-turbo each bend, and take the uber shortcut. Cut across the clouds at the end.
Yoshi Circuit- mini-turbo each corner, take the first shortcut with a mini-turbo on all lap and cut the grass near the final piranha plant.
