The bidding has closed on the Singapore gaming licenses and so far as anyone can tell Las Vegas Sands has offered the biggest deal. The Venetian company is promising to spend $3.6 billion on its resort, reports Bloomberg.

That would make the Singapore casino the most expensive ever built anywhere. It would include 2,500 hotel rooms, 1.2 million square feet of convention space and 1 million square feet of shops. Nothing like going all in.

All of these bids are pumped up because the casino is supposed to be a part but only a part of a much larger resort that Singapore wants to build to boost its flagging tourism business, which had been a key part of the city-state's economy. In fact, the casino is planned to focus on high rollers and keep out the rank-and-file locals who want to try their luck.

Sands' Malaysian rival Genting Bhd. has promised to spend $3.1 billion on its resort. Harrah's and MGM Mirage have not spelled out their bottom line but they have in recent weeks been promising all kinds of goodies like Harrah’s plan to build Star TV studios and the iPort multimedia theme park at its resort, and MGM's promise to bring Cirque de Soleil to Asia.
