From Week 1 through the Super Bowl, you will pick one team to win each week (you could pick the Chiefs every week if you want). If your pick wins, you move on to the next week. If you have multiple entries, you can pick the same team twice, or pick multiple teams. If you have two entries and one of your picks wins that week and the other loses, then you move on to the next week with one pick. When you are out of picks, you're out.
You are allowed to buy back in as many times as you want until Week 10. After Week 10 is complete, it is sudden death with no re-buys from then on.
When there are 5 or less teams standing, a vote will be cast to continue playing or have everyone split the pot. This vote has to be unanimous. If there are 5 teams left, and 1 person decides they want to risk it and keep playing, then the contest continues.
Each remaining team heading into the Super Bowl will pick a winner for the Super Bowl and the total amount of points scored. If two people both pick the eventual Super Bowl winner, then the person who has the closest total amount of points for the Super Bowl wins.
