Legalized gambling? In New York City? Bet on it.

Video slot machines are whirring at Aqueduct race track after a decade of controversy.

Several thousand people came through the doors when it opened to the public on Friday afternoon.

The so-called “racino” will have 4,525 video slot machines and 475 electronic games to start. Thousands more will be added later, along with other casino-like amenities.

More than 1,300 jobs were created to build the flashy facility.

It includes 18 food and beverage courts, including two restaurants, four VIP lounges, a bar and theater for music and comedy acts.

It’s run by Genting’s Resorts World New York.

Officials hope it will provide millions of dollars a year in much-needed revenue to the cash-strapped state and its racing industry.
