How to Snake in Mario Kart DS

Learn to use the Mini-Turbo. The mini turbo is the basis of snaking, and when you condense it all down, all snaking really is, is enhanced use of it. First, when going around a corner, press and hold "R" to begin drifting. This allows you to take on corners without losing speed. Next, to perform the mini-turbo, press on of the arrows on the D Pad (what you use to steer) back and forth to make the sparks under the back wheels turn blue, and subsequently red. Once they are red, let go for a mini-turbo. It gives you a small speed boost.

Get used to using mini-turbos in succession. On long turns, use the mini-turbo over and over to maintain a high speed. In doing this, you are almost snaking, and already using the concept of it to your advantage. Because you're still turning in a certain direction, this is a good way to get comfortable with mini-turbos. Try to fit as many mini-turbos into a turn as possible to further prepare yourself for actually snaking.

Learn to use mini-turbos on straight tracks. A good course for this is Figure-8 Circuit due to its long, straight, and decently wide track. Do a mini turbo just as you would on a turn. Then once it has been completed, let go of R and quickly steer your car towards the opposite way you were drifting, and hold down R again and do another mini-turbo. If you've done this, you're snaking! Just learn to use more and more in a row until you feel good about it. Once you have been doing it a lot, it becomes second nature and without even thinking you'll suddenly be able to defeat even some of the best online racers.
