Nitro Grand Prix
In Mario Kart DS, there is a section of the Grand Prix mode called Nitro Grand Prix (also called Nitro GP or NGP). It is one of two sections of the Grand Prix mode. In the Nitro Grand Prix, there are four different cups to choose from: The Mushroom Cup (containing the easiest courses), the Flower Cup (containing courses of intermediate difficulty), the Star Cup (containing difficult and tricky courses), and the Special Cup (containing the most difficult and longest of all courses).
Each cup has four courses. The courses are as follows:
- Mushroom Cup
- Flower Cup
- Special Cup
In order to play the Star Cup, the player must place first in the Mushroom Cup and the Flower Cup (it does not matter which order). And in order to play the Special Cup, the player must place first in the Star Cup. By placing first in the Special Cup, the player will unlock something depending if it is played on 50cc, 100cc, 150cc, or 150cc Mirror.
