In the last part White got the prize (immunity) and Brown got eliminated.
White will start right at the finish so he is guaranteed to be safe.
Who will be eliminated? Who will get the immunity prize besides White? Will Tan or Orange now fall because they lost their sibling?
Find out in part 4 of Nick781's Marble Race! (credit to jspero77 for some of the stuff used in the race)
Make sure to tell me who gets 1st (besides White) and last in the comments!
Press enter/return to start and press and hold "d" when all marbles finish.
