ESPN Streak for the Cash - Super Saturday 2012 (the "Stunt") is open only to legal residents of the fifty (50) United States and Washington, D.C., Mexico, United Kingdom, and Canada (excluding Quebec), who are eighteen (18) years or older, or age of majority in their jurisdiction, whichever is older, as of the first day of the Stunt Period (defined below), and are registered members of ESPN.com.
So there are a few countries that can do it. Also, you can only do 1 pick at a time, NOT one pick per day like most people think. When your first pick wins or loses you are free to choose again so it helps to pick early games first or minigames.
