More Bonus Boards and Mirror Tracks
You must have all levels open completely, and the best record on each track on each difficulty has to be beaten. (ex. you must beat the track records on say, polar paradise, on easy, medium, and hard). A ghost should appear on the hard setting on the track.
Beat the ghost and earn a bonus board. Then, play with that board against on the same track again. (ex. you will earn the 'Jake' board when you beat the ghost on polar paradise, so use the jake board against him)if you beat the ghost, you will earn the mirror of the the track! These are the boards you must use on the certain tracks:
Twisty -- Twisty Canyon
Jake -- Polar Paradise
'55 -- Splash Down
Tareh -- Glacier Gluch
Typhoon -- Easy Slider
Lynwood -- Funky Town
