While Sony is a sponsor of the show and some prizes might be Sony products, winning has nothing to do with having a Sony card. To be a contestant on Wheel of Fortune, you need to:
* Audition: Submit an application through the show's website.
* Be selected: The show's producers choose contestants based on various factors.
* Participate in the game: Once on the show, your skill at solving puzzles determines your chances of winning.
So, relax, enjoy the show, and maybe you'll even get a chance to be a contestant!
