As I've said in winner announcement post since we have 14 3/3 answers and only one prize of 1 STEEM (for this group), prize pool was modified. I've expected that more people would guess 2/3 than 3/3, but it was the other way around. So its only fair to divide prizes amongst majority of people who guessed all of the answers correctly.
If that doesn't make sense or you have a suggestion for future contests, then please let me know.
