ATLANTIC CITY, N.J. (AP) — Six of the seven casinos given permits to conduct Internet gambling in New Jersey were cleared to start taking bets Thursday night, while one — the Golden Nugget Atlantic City — was left out of the test after its systems did not pass rigorous state testing.

The casinos approved by the New Jersey Division of Gaming Enforcement collectively will offer 13 websites where customers can make real-money bets starting at 6 p.m.

The participating casinos are the Borgata Hotel Casino & Spa; the Tropicana Casino and Resort; Trump Plaza Hotel and Casino; the Trump Taj Mahal Casino Resort; Bally's Atlantic City and Caesars Atlantic City.

The test period was established to determine whether sophisticated technology designed to ensure that all gamblers are in New Jersey and at least 21 years old works correctly. The test also will evaluate electronic payment technology and the integrity and functionality of the casino games.

If all goes well, Internet gambling will be available to gamblers in New Jersey starting Tuesday. The only other states to offer online gambling are Nevada and Delaware.

Online betting will mark the biggest expansion of gambling in New Jersey since casino gambling began in 1978.

"This is a very exciting time for Atlantic City and for the gaming industry," said Alisa Cooper, a commissioner with the New Jersey Casino Control Commission.

"With the dawn of Internet gaming, we are on the cusp of perhaps the biggest change — and challenge — since the first casino opened here," Cooper said.

Hours before the test was to begin, a state lawmaker unveiled a proposal to lure foreign online gambling companies to New Jersey. Sen. Raymond Lesniak's bill would entice foreign betting firms to set up shop in the state — even though they could only take bets from overseas gamblers — and be subject to New Jersey's famously tough casino regulation.

The payoff to New Jersey would be a 15 percent tax on their winnings, plus payments into a fund to raise $20 million a year for three years for New Jersey's struggling horse racing industry. Lesniak said the foreign companies want the stamp of approval that strict New Jersey regulation would bring.

PokerStars, the world's largest poker website, was not cleared to participate in the test with its land-based casino partner, Resorts Casino Hotel. PokerStars spokesman Eric Hollreiser said the company is continuing its talks with the state Division of Gaming Enforcement.

"However it is now apparent that we will not have approval in place to launch on Nov. 26," Hollreiser said. "We remain committed to working with the division to complete the review process."

Regulators say from 500 to several thousand people could be online at any one time during the test period. Gaming Enforcement Director David Rebuck said he hopes to push the system and test its capacity.

He said all indications suggest the system should work as designed to meet strict regulation and protect players.

"I'm cautiously optimistic," he said. "Testing has been going on for months. I don't think there is any online gaming anywhere in the world that is going to be monitored as closely and protect the integrity of the games and players' money as well these will."
