There is a common opinion that in order to earn money in a casino, one must be the owner of this casino. But the history knows cases when thanks to the mind and ingenuity ordinary people managed to beat the casino in large. One of the first people who managed to beat the roulette was Joseph Jaggger. It is known that Joseph Jagger was born around 1830, and also that he was the ancestor of the famous rock musician from Rolling Stones Mika Jagger. Jagger worked as a mechanical engineer at a cotton factory in Halifax, in the county of Yorkshire, and during his time as an engineer, he liked to go to the casino. During the next game in roulette, the inquisitive mind of the engineer made Jagger think about the randomness of falling numbers.
