HONG KONG: Sands Macau is claiming to be the largest casino in the world after expanding its gaming rooms. Sands opened a new third floor, boosting the number of gaming tables by almost two thirds to 740, reports said, quoting a statement. The existing two floors -- including VIP rooms -- have also been extended, the company said, and the casino has also boosted its slot machines by 365 to 1,254. “The addition of these tables now confirms Sands Macau's position as the largest casino in the world,” the statement said. Earlier this week, the gaming operator signed a Development agreement" with the Singapore Tourism Board (STB) to build a US$3.2 billion integrated resort. Sands won the bid three months ago and will complete the complex in 2009. Marina Bay Sands will have massive exhibition and convention space as well as a casino and other facilities.
