With the field for NBC's hit reality series "The Apprentice" narrowed to six, everything in Thursday's episode hinged on the roll of a dice. But the gamble didn't pay off for Katrina Campins, who was the latest contestant to get fired by The Donald.

At the onset of the show, Protege was down to two members -- Troy and Kwame -- after Heidi was voted out on the last episode. In order to even the teams, Protege was allowed to pilfer from their opponents and they selected Bill, which left Nick, Amy and Katrina remaining on Versacorp.

This week's task was drumming up business for Donald Trump's opulent Taj Mahal hotel and casino in Atlantic City, N.J. Each team had to register as many gamblers as they could, and then get them to spend as much money as possible.

Protege, which was headed by Kwame, hit the ground running, setting up a "Wheel of Fortune"-style spinner that would enable registered gamblers a chance to win a $1,000 prize and other goodies.

Versacorp, meanwhile, opted to give away a $300 voucher good for a car rental—a deal that had Amy steaming when Katrina tried to use her charm to score an arrangement with the car salesman.

That night Amy and Nick's romance continued to heat up, as the girls from Versacorp bedded down in one room and Nick went to sleep in an adjoining suite. "I don't know how I feel about Nick and I don't know where it will go," Amy told the camera. "Maybe it's time to find out."

At the end of the competition, Versacorp had signed up nearly twice as many gamblers as Protege had. But Protege's gamblers had outspent Versacorp's by nearly 20 percent, leaving Protege the winners.

It was Amy's first trip to the boardroom, where she sent Nick back to the suite and elected to go before The Donald with Katrina, who she claimed had not offered much to the challenge.

"I think your concept was terrible," Trump said, as he blasted Versacorp's plan to give away a $300 prize in Atlantic City. "You should have given away a car," he said.

After grilling Amy about her and Nick's relationship, Trump fired Katrina, citing the fact that Amy had won the approval of her peers and had never before been to the boardroom.
