(Also I forgot to mention, the marble with the second-to-least points gets a disadvantage.)
Red is eliminated with -20 points! (Red was my favourite colour, by the way. )
Pink's prize = Headstart
Tan's disadvantage = Increased air friction multiplier (This should make the marble slower.)

Also here are the UPDATED rules for anyone confused:

Main Rules
----------
The marble with the most points will win a prize.
The marble with the second-to-least points will get a disadvantage.
The marble with the truly least points will leave the game.

Exceptions
----------
A marble cannot get the prize if they already earned it up to three episodes ago.

If a marble is second-to last place twice or more times in a row, there will be no disadvantage.
