The challenge is even greater with the need to collect coins - in the Super NES version, they were important in keeping your vehicle's top speed high, as well as creating a buffer from getting spun-out by an opponent's nudging.
The game is extremely challenging in single player mode, because the AI of the computer opponents increases the deeper you get into the game - if you think the game's easy in 50CC mode, don't blink when you're bumper to bumper with the rest of the pack in the 150CC races. You'll have your pick of one of eight Mario Universe characters, from Mario and Luigi to Bowser and Yoshi, each racer having his or her own driving attributes such as speed, acceleration, and overall weight to push around the other players. The only way to progress through the five Cups (four available, one hidden) is to place first in each of the game's 20 tracks in 50, 100, and 150CCs modes, each being a faster and tougher class than the one before it. Mario Kart Super Circuit builds upon the original design of the SNES version, with multiple circuits of four tracks each in place for the single player mode.
