    If the expected value is positive, then by all means you should play the lottery. Just bear in mind that the utility of money is nonlinear, so Kelly will overextend you - use something like max log-value and rederive.

    The only time this happens are either scratch off tickets that are horribly broken or rolling-jackpot lotteries where you can win what other people put in before you.

      Even if the math works out that the lottery would be EV+, you still can’t know for sure it isn’t crooked

        Lotteries are generally regulated but corruption isn’t unheard of.

        But outside regulated state sponsored lotteries - it’s safe to assume it’s crooked in one way or another.
