There was a story in New York some years ago about someone winning a $20M jackpot in a Pick-6 drawing. I believe that was the largest jackpot in New York history at the time. The following week, there was a new jackpot of several million dollars that got split so many ways that each winner got less than $10,000. The winning numbers were a sequence like 5-10-15-20-25-30 or something like that, and there were literally hundreds of people who played that exact same set of numbers.
It might have had something to do with Chinese fortune cookies- that’s how the same number showed up so many times.
