My wife swears that it's the person that drives the luck. I'm a math guy and "luck" is a strange idea to me. That said, I haven't kept track of my royals but there have been a lot. She plays almost as much as I do and her royal tally is far far lower. The same holds true for 4OAK's . I usually more than double her scratch card total at MSS. I have no explanation. If she has a run where she catches up to mathmatical expectation, that will be a GREAT trip.
