Winning millions with scratch cards?
Joan Githner, 63, from Texas, won more than 20 million dollar with American scratch cards. Githner is also a former math professor with a PHD from the in statistics Stanford University.
The odds of winning a scratch card should actually be completely random, but according to Joan, this is not the case, otherwise the lottery commissions can’t determine their profit margins. Each scratch card belongs to an algorithm (a complex mathematical formula), this algorithm is specifically designed to determine the number of scratch card winners. According Joan; algorithms are not completely random and this math professor is quit handy with them.
A recent article in Harper’s Magazine doubted Joan Githner luck of winning more than 20 million dollars. The article suggested that Joan cracked the scratch card algorithm. According to the article this was done by determining when the winning scratch cards were printed and he had tracked all four winning tickets back to a supermarket in Texas.
It will not be the first time that a scratch code has been cracked. In 2003, Mohan Srivasta (geological statistician) discoverd a pattern on the scratch layer. Mohan was considering to quit his job and to play scratch cards full time but later he changed his mind, and contacted the Ontario lottery. The scratch cards were pulled out next day because of a “design flaw”.
