When I was in school, barely old enough to be in Vegas, I played a 50 hand VP machine. I had no idea how much it cost; I just knew that it said 25 cents and that I was supposed to play max bet no matter what to maximize my odds of a big payout. So I hit the max bet button, and saw damn near my entire $100 go by the boards. "Oh, #$&%, I thought I was playing for like $1.25 per hand!" Poor naive stupid me. I wound up getting dealt three of a kind, holding those cards for all 50 hands, and getting a hand pay. Poor naive stupid me turned into rich naive stupid me! (Well, by the standards of an undergrad, anyway.) Have you ever made a gambling mistake that wound up panning out in the end?
