I am bit confused when I opened up the link, I don't know if you can clear some of the rules partaking the contest
Sorry for the confusion. The prize is $100 BTC. It's not a free play. Bastketsrus and woodie made their plays correctly. Here are plays from woodie. He sent by PM but best to post here so we can all see.
Here are woodie's plays.
Michigan
156 points
13 margin
So woodie took Michigan to win the game. He thinks the points by Michigan plus the points by UConn will equal 156 points. Then he thinks Michigan will win by 13 points.
