A New Jersey woman won nearly $300,000 while playing an online slot-machine game during a work call.

The unidentified Mantua resident “was actually on a work conference call and almost screamed out loud” when she won the $288,000 prize Aug. 2, she wrote in the SugarHouse Online Casino chat room, according to NorthJersey.com.

The online casino’s operator confirmed the win.

The lucky lady had placed a $2 bet while playing the popular video slot game Divine Fortune when she won the jackpot.

Her payout was the biggest prize won by someone playing the ancient-Greece-themed game since the Philadelphia-based SugarHouse Casino entered New Jersey’s online gambling world in 2016.

In March, 33-year-old Anibal Lopes of Woodbridge won $193,737 while playing Divine Fortune online.

“I couldn’t believe I won that much money,” said Lopes, a superintendent for a construction company. “I told my wife, ‘I don’t feel well. My legs are shaking.’ She said, ‘We need to get you to the emergency room.’ I told her, ‘No, I’m not sick. I just won close to $194,000!’ ”

Richard Schwartz, president of the online casino’s operator, Rush Street Interactive, said the jackpots “prove people can win life-changing amounts online at anytime and anyplace.”

The most recent big winner started playing with the casino in January, according to a press release from Rush Street Interactive.
