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