Important Competition Rules

As Jam City Rollergirls is currently only available in North America, this contest is only open to users in North America. If you live outside North America, you cannot win, even if you have a North American Wii. Sorry folks, but them's the breaks.

Nintendo Life will contact winners through their Twitter account this weekend. If users have not replied with their contact details before Tuesday, February 15th, they will forfeit the prize and another winner will be chosen. Monitor those Twitter feeds this weekend and next Monday!

The contest starts today, so keep your eye out for the message to retweet.
