A new "Bucks" episode is released every Tuesday and Thursday, and the latest one returns to Marlins Park in Miami with a little help from the stadium organist.

Watch episode 18 to see how it all turned out for vacationing Kurt Wilson of Connecticut and Marlins fans Ashley Rose Justice, Lana Scherrer and Marissa Norman of Florida.

"Bucks on the Pond" is hosted by Jeremy Brisiel, and you might be a part of it when you least expect it. Fans at the ballpark interact with MLB.com's studio through the magic of technology in conjunction with game action inside. In creating a new experience for fans, MLB.com is giving people a chance to earn bucks while they spend bucks at the ballpark.

Contestants are asked a trivia question -- general knowledge and baseball -- on each pitch during a half-inning of baseball. Get the question correct and win money. Get the question wrong and it's a strike. Three strikes and you're out.

The questions' difficulty and value increase with the number of outs in the on-field action: $5 easy questions to start, $10 medium-difficulty questions after one out, $20 hard questions after two outs. If the contestant lasts longer than the team's at-bat, they win the bucks in their bank.

"It shows that it pays to have useless knowledge sometimes," David Martinez said after episode 3, which also was taped on the left-field concourse in Miami earlier this season. "It might even bring more people out to the stadium to watch the segment being filmed or to see if they can get on the show."

Remember episode 8? That was another Marlins crew, one of the better costumed contestant groups of the season, featuring Green Man and Mr. America. After they won some bucks, Kevin Velez said, "Being part of a game show at Marlins Park was great. We enjoyed the game and won some 'Bucks on the Pond.' It doesn't get much better than that."

So, how did this Marlins bunch turn out? Episode 18 even featured stadium organ music for the first time -- just in case anyone thinks the national anthem includes the lyrics "O beautiful for spacious skies." While the contestants encountered some difficulties on that front and were not granted their wish for multiple-choice questions, they did nail a fair amount of geography and pop-culture questions, and we'll see if they know anything about Oompa-Loompas.

In addition to the Marlins, teams visited so far include the Cubs, White Sox, Yankees, Reds, Red Sox, Astros, Royals and Orioles. Bookmark MLB.com/bucks and be on the lookout for the "Bucks" crew at your ballpark.
