Prizes are all guaranteed eventually
Thats not so much guaranteed as it's virtually impossible to get 80 boxes of each. Unless your Willink to spend a lot of donuts on eggs. Edit: 81 gold boxes? At this rate ill be there in 2155.

I haven't even cleared the boxes in my common color, let alone any of the other boxes. I've had pretty decent luck in all the other events, but my chances of clearing all the prizes in this event is looking pretty slim.
