The last of the four voter-approved casinos in Ohio geared up for its March 4 opening Tuesday by giving members of the news media a sneak peek inside the $400 million facility.

The Horseshoe Casino Cincinnati looked every bit like a fully functioning casino with its 100,000-square-foot gaming floor, 2,000 slots, 85 table games and 31-table World Series of Poker room. The only thing missing Tuesday were the gamblers.

“Bring the dice in! What are you waiting for?” yelled a supervisor at a craps table where dealers took turns pretending to gamble and testing themselves.

Horseshoe Cincinnati, located in the city’s downtown, is expected to generate $100 million in tax revenue via 6 million visits annually, according to casino officials. Once open, it will be a 24-hour, seven-days-a-week operation employing approximately 1,800 full- and part-time workers.

Those working Tuesday were also preparing for a dry run of the two-story, 400,000-square-foot casino on Wednesday, when about 30 agents with the Ohio Casino Control Commission will be on the lookout for problems.

While the casino already has its gambling license, it must pass the commission’s test on Wednesday in order to open to the public on Monday.

If there are no major issues, the casino would get the go-ahead by the end of the week. If any major operational problems arise, the opening could be delayed.

“Think of it as a dress rehearsal,” said Matt Schuler, executive director of the commission. “It’s an opportunity for the casino and its employees to show they can do everything by the book — security, surveillance, all financial transactions, the movement of the money from the floor to the count room. We will watch everything.”

Casinos in Cleveland, Toledo and Columbus all opened last year on time after their dry runs.

The invite-only dry run is for family, friends and business partners of the casino’s staff, and is closed to members of the media and general public. All proceeds from the dry run will go to charity.

The facility includes a buffet, three outward-facing restaurants, including the tropical-themed Jimmy Buffett’s Margaritaville Restaurant and Jack Binion’s Steak. And a 33,000-square-foot meeting and event space on the casino’s second floor includes a pavilion that can seat up to 1,400 people for shows and concerts.

But what sets the Horseshoe apart from other casinos is its design and 1-acre event lawn, said Steve Rosenthal, principal of Rock Gaming LLC.

“You see other casinos that are more like fortresses … that people walk in and do everything inside the casino,” he said “Our casino is a bit different. We’re located in the middle of the city with restaurants on the outside of the facade, where you can actually walk into the restaurants, eat, maybe check out some entertainment there where we have some bands or what not, and then walk out of the casino without having to walk into the gaming floor and feel like you have to go through the gaming floor to get to these restaurants.”

Horseshoe’s event lawn will be used for not only casino events, such as concerts, but community events, as well.

“It acts as a park during the off time and it acts as event venue other times,” Rosenthal said. “It’s truly a unique part of the venue.”

Gaming options include everything from 1 cent to $500 slots, plus high stakes table game rooms with minimum bets of $500 and maximum bets of $50,000, all under the Caesars Total Rewards program. A World Series of Poker room is “the ultimate man cave … for women, too,” said Chip Gerhardt, a Rock Gaming representative.

Ohio voters approved four casinos in 2009 after a statewide legalization campaign touted the immediate boost the casinos would give Ohio’s economy. The state collects 33 percent in taxes from the casinos, which is distributed to Ohio’s schools, counties and cities.

Profits have fallen short of expectations thus far. The four casinos were predicted to earn just under $2 billion a year once they were all up and running, which would generate about $643 million in taxes. Since opening, the Toledo, Cleveland and Columbus casinos have earned just under $404 million through January, generating about $133 million in taxes.
