The chance of picking a perfect bracket randomly must be closer to 15 billion than 15 million. But still worth a try, right? Especially with the $100,000 prizes (you actually compete against the 15 million suckers, not against insurmountable odds)
Perfect bracket = $1 billion
Top 20 = $100,000
Limited to 15million entries (only first 10million eligible for $1billion prize)
Worth a shot if you do brackets and enter them elsewhere. I used to do tipping comps for money, and the trick was to enter as many as possible so when you win, you win big :P
Odds: Grand Prize – 1:9,223,372,036,854,775,808, which may vary depending upon the knowledge and skill of entrant
