If you're putting money into a slot machine, you're not smarter than a 5th grader.
If you're into it enough to think it merits an entire magazine about the subject, yes. Twice a year my best friend and I go up to one of the casinos here and drop in a few bucks in memory of her father. I think of it as a nice tribute and my twice-annual donation to our Native American population, but I also go into it not expecting to see that $40 ever again.
