I would be really curious to see the money side of this. I am not sure about Powerball, but with EuroJackpot, some of the smaller wins can cover the cost of the ticket (or even cover a holiday!).
It would be really interesting to watch the expected value play out over repeated plays!! I am imagining a running balance where you keep track of total spend versus total returns. Most of the time the balance steadily goes more negative, with occasional jumps back up when you hit a partial match, and very rare big spikes from a larger win.
Very cool project!
