Instructions
Collect 100 "Stopwatch" power-ups. There is no special technique to achieve this requirement; the Stopwatch icons are randomly scattered throughout all the courses. Collect them whenever you are able and they will be added to your running total.
Earn five lights in a "Checkpoint" event without using Nitro. There are events in the higher groups that do not allow the use of Nitro. Win these events and hit the score target in order to be awarded five lights. The fact that Nitro is not available will prevent you from picking up the power-up accidentally.
Earn five lights in a "Checkpoint" event without collecting a Stopwatch power-up. Unlike the Nitro-less events, all the "Checkpoint" events feature stopwatch power-ups. Look far ahead down the road while driving to keep an eye out for the banks of power-ups. Learn to recognize the Stopwatch icon and avoid it when passing through the arrays of power-ups.
Nitro through every checkpoint in a "Checkpoint" event. This may take several attempts. Learn the location of the Checkpoints on any of the courses and hit your Nitro just before you pass through one. Don't press it too early so that it runs out before you clear the Checkpoint, and avoid hitting the button while in mid-corner, as this could cause a spin.
