Voting rules: Choose the competition you think is the most difficult!
This is a community-based ranking of the most difficult competition to identify. We do our best to provide fair voting, but it is not intended to be exhaustive. So if you notice something or competition is missing, feel free to help improve the ranking!
A participant may cast an up or down vote for each competition once every 24 hours. The rank of each competition is then calculated from the weighted sum of all up and down votes.
