The viewer who responds with the most correctly spelled words will win a prize, according to a press release.

Users can also warm up their spelling skills by logging onto the Facebook Spelling Game and challenge friends to see who can correctly spell the most words of the over 1,000 that will be used in Sunday night’s broadcast.
