When I was a young whippersnapper, if you played slots, there were three reels, and some variant of 7s was involved. I loved the Red, White, and Blue game the best. Now, you have a new "themed" slot rolling out every other week. It seems like yesterday everyone was in love with WOZ machines. What about The Walking Dead? Now, it's those damned BUFFALOOOOOOOOOOOOOOOOOO! What is the shelf life of your average slot machine these days?
