A group of Singapore investors are out millions after scammers convinced them they had a system for beating the casinos.

This weekend, the Straits Times reported that a High Court lawsuit had been concluded following a confidential agreement between the warring parties. Among the details revealed via the lawsuit were that a group of around 150 individuals may have been conned out of up to SGD50m (US $36.7m) by a shadowy group known as SureWin4U.

SureWin4U ran a website offering the opportunity to invest in various sized ‘packages’ based on the casino winnings of a group of so-called “expert gamblers.” The gamblers, whom the site claimed were from 21 different jurisdictions, boasted of a 99.8% success rate.

The lawsuit’s plaintiff, a 44-year-old diamond merchant named Lee Hwee Yeow, said he attended a ‘demonstration’ of the gamblers’ prowess at the Marina Bay Sands integrated resort in June 2013. Lee claimed he witnessed some other investors each give the gamblers SGD3k, and received returns of SGD300 within 45 minutes.
