Mandel designed his successful formula while working as an economist during the 1950s in his native Romania. After many calculations, he came up with the formula that would give him success: a combination of mathematical operations that could predict five of the six winning numbers out of a total of 40 options.
The mathematician aspired to obtain a second prize, which only required five hits, but to his surprise, the play he made with three friends won the first prize in the local lottery., according to public laguardia.com.
Already with money in his pocket, Mandel settled in Australia in the 1980s, where he soon decided to see if his formula would bring him the same luck. However, being a different system, he did not attempt to predict the winning combination; With the Australian lottery, Mandel opted for another method: getting as many tickets as possible, all with different combinations. Thus, his probabilities increased, and his method was more than successful, since he managed to win 12 prizes from the raffle during the times he tried. With the winnings, Mandel decided to start a legal investment fund employed in one task: working with his formula to win the lottery and distribute the benefits.
For Mandel, it was key to get hold of the possible number of combinations that the draw could have. For a lottery where you have to choose six correct numbers between the numbers 1 and 40, the possible results are a total of 3,838,380 combinations, for which Mandel made sure to try his luck in draws in which the prize was three times greater than the number of possible combinations.
He soon obtained the interest of his acquaintances, who together with the profits of his company was invested to accumulate money for the purchase of the range of possible figures in different bookmakers. Once the prize was collected, he distributed it among all those who had collaborated.
His success led him to try his luck in the United States, where he also won several awards that brought him some 30 million dollars during his stay in North America.
But his fortune attracted the attention of the FBI and the CIA who began to investigate him. And in addition, it led the US lottery authorities to modify the rules and limit the number of shares that each player could acquire.
Mandel ended up emigrating to Israel in 1995, from where he tried to replicate his business success, but found himself under investigation by the Securities Authority.
In 2004, he was sentenced to ten months in prison and a fine of almost $ 30,000, as he and his partner did not reveal to their investors their true chances of winning.
