lottery machine fraud

The 1980 Pennsylvania Lottery scandal, colloquially known as the Triple Six Fix, was a plot to rig The Daily Number, a three-digit game of the Pennsylvania Lottery. All of the balls in the three machines, except those numbered 4 and 6, were weighted, meaning that the drawing was almost sure to be a combination of those digits. The scheme was successful in that 666 (one of the eight combinations of 4s and 6s that the "fixers" were hoping for) was drawn on April 24, 1980; however, the unusual betting patterns alerted authorities to the crime. The chief conspirators were sent to prison, and most of the fraudulently acquired winnings were never paid out.
