Rainbow won for me, I gave the marbles a personality so that there was a reason for me to eliminate that marble (other than choosing the color i liked the least), and when it came to the point where I didn't know which one to eliminate, I eliminated one at random. Rainbow won, Navy 2nd, and Orange 3rd
I forgot to mention, for normal mode a single combination can have up to 3 ideas for it, also, windstorm added! @Danga, would you like to add a comment to the element?
