- The Special Challenge Card is purple. 

- Special Challenges must be completed within the displayed time limit! Complete these challenges before the countdown ends. You are able to earn extra Trip Points by completing them. If the Special Challenge is not completed in time, it converts into a normal challenge (but your current progress will be saved).

- When you log in to the game for the first time each day, one of the four challenge cards will turn into a Special Challenge card. Also after completing the first task of the day, a new Special Challenge card will be refreshed.
