I wanted to clear something up before the game tomorrow. I have added this to the main rules:
What if there are multiple winners of which none of them win the proceeding block?
Remember, there has to be one winner. In this case, they would all simply proceed together to the next block until we can eliminate all but 1 piggy. If those winners had the same entry number though, then we stop the game and details of the final round (Sept 2nd) are announced.
tomorrow final round

Tomorrow are the elimination rounds so that we can narrow it down to a single entry number.
There will only be a final round on September 2nd...
IF, after the elimination rounds, the final entry # represents multiple users.
This is actually very likely, since there are at least a couple hundred contestants and only less than a hundred entry numbers.
