When I turned 21, I went and played "Family Feud" and "Pyramid". "Feud" just lightened the weight of my wallet, but "Pyramid" won me $50. When you talk about slot machine payouts, not too shabby. It was a penny machine, at that.
Slightly off-topic, but I later played "Dick Clark's Bloopers" machine, and got about $15, and thinking (foolishly) that Dick Clark slot machines were my lucky charm that night, I played the "American Bandstand" machine. I ended up losing $40, so I'll say this: it didn't have a good beat, and I certainly couldn't dance to it.
