There's a change however to the game this time around and the winnings are big.
"This is a year-long tournament and it's going to take place over 9 months," said Alex Trebeck, host of "Jeopardy". "Each month, one celebrity game followed by a week of semi-finals and a 2-game final match for that million dollars."
That million dollars is for the charity of each celebrity's choice.
"And we're bringing back celebrities that have played the game before so they know what to expect, they're not as nervous, they're going to perform a lot better," said Trebek.
Eyewitness news caught up with the players during a rehearsal for the big show.
"It's fun but it's nerve racking," said Delany. "I remember the last time I played I think I lost 5 pounds. It's really scary?I'm up against 2 braniacs. I've got Wolf Blitzer and Andy Richter. I think Andy Richter is one of the highest scoring players of all time."
"Wolf is the one," said Richter. "He's actually the one who's got to sort of thing on his feet now and then and know stuff about stuff whereas Dana and I just have to look beautiful."
The first round of "Celebrity Jeopardy" airs Thursday evening at 7:00 on ABC7. Episodes will broadcast every third Thursday through May, culminating into the ultimate 2-day final rounds.
