There are no opponents nor any team-mates; just you and the board...and a large rotating rotor in the background.
You will be playing two rounds in this scenario, the first is standard but the second run you must complete backwards.
To make things slightly more difficult, in the second run, the board will change to prevent you from following the same path in the first run you did.
