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