Pardon me if my age shows while I switch into "kids these days" mode.
It seems the sole source of entertainment for kids these days (see, I told you) are video games. Sure, they come in a variety of platforms, but they're still video games. Pre-Atari, I didn't have much exposure to video games. But there were variety of options for game play I could choose; board games, cards, outdoor physical *gasp* games, and early electronic games. And for a brief time in the late 1970's mixed among those other choices was a line of mechanical pocket games made by Tomy and other companies.
I remember going through bins of these at a local store as a kid, trying to decide which held the most fun and game play.
I found a couple of these this past summer. I had this Jackpot game in yellow. Pull the lever, let it spin, push to button to stop the reels on a dime. Of course, nothing ever dispensed for hitting the jackpot, but it felt great just the same.
