Tuesday's opening includes the casino and 963 out of 2,560 hotel rooms, a portion of the shopping mall, some restaurants, an exhibition centre and the events plaza.
The remaining hotel rooms and suites, a skypark and more shops will open on June 23, while a museum, theatres and other stores will start operations later in the year, the management said.
Officials hope the casinos will help Singapore achieve a target of attracting 17 million visitors a year generating over 21 billion US dollars by 2015, supporting the services sector and reducing the role of manufacturing in the economy.
"This second casino is another boost to the economy, which has been doing much better," said economist David Cohen at research house Action Economics.
"It should support tourist arrivals, and the retail sector should benefit from that especially now in the midst of the improving global outlook," he told AFP.
Singapore's economy surged 13.1 percent in the first quarter from a year ago, prompting the government to sharply upgrade its growth projection this year to 7-9 percent from 4.5-6.5 percent.
Cohen however is projecting higher growth of 9.5 percent this year.
"Singapore already enjoys a very convenient (global air) transportation network which makes this an attractive place for people to come from around the world," he said.
Marina Bay Sands is designed to cater to the corporate and convention crowd while Resorts World is aimed at families.
The Marina Bay Sands casino will offer 600 gaming tables, more than 1,500 slot machines and over 30 private gaming rooms. It occupies four floors, the bottom two for mass gaming and the upper section for premium players.
The Resorts World complex, located on Sentosa island, includes Southeast Asia's only Universal Studios movie theme park, hotels, restaurants and convention facilities.
