You get 3 minutes to finish a track. Less time you use, more points you get. Each time you overtake an opponent, you win 100 bonus points. If they overtake you, you will lose points. The total of the best score of the three tracks will be your final score.
Use the up arrow to accelerate, the down arrow to break, the left arrow to turn left and the right arrow to turn right. Press Shift to speed up 3 seconds.
