Knowing your country music trivia can certainly pay off. The Grand Ole Opry has launched its online Country Music Video Challenge, with lots of great prizes for the winners.

The game, which benefits flood relief efforts in Nashville, features video clips of country music performances followed by questions about the clips and the artists featured in them in addition to trivia questions such as:

What movie has Darius Rucker seen more than 100 times?

Taylor Swift was born in what state?

Which Dolly Parton duet partner inspired her smash hit, 'I Will Always Love You?'

Beginning today, country music fans can log onto opry.com, and by playing the trivia game, fans will be entered to win prizes including a Gibson guitar autographed by Brad Paisley, $500 cash, and a trip to Nashville including VIP tickets to the Opry.

Throughout the challenge, players are invited by their favorite country stars to donate to the Community Foundation of Middle Tennessee's flood relief fund. Humana has pledged to donate $1 for each of the first 25,000 fans who play the game.

The Opry, which has been temporarily displaced from its permanent home in the Grand Ole Opry House by the May floods, has not missed a show due to the flood, relocating to the historic Ryman Auditorium throughout the summer. The show is scheduled to return to the Opry House in celebration of its 85th birthday in October.

Players who participate in the trivia game will be able to challenge their friends in the game via Facebook and Twitter. "The 'Challenge' is a great way for country music fans to assist with Nashville flood relief from their computer keyboards, competing with their friends to see who best knows their Kenny Chesney from their Kenny Rogers, and their 'Your Cheatin' Heart' from their 'Before He Cheats,'" notes Angie Reynolds, Opry Interactive Manager.
