The Largest Advantage

Just curious, what was the largest advantage you or anybody has ever had in any casino game that you've heard of? No cheating.

I was one of 20 people in the casino during a $50,000 total giveaway with 10 winners. I didn't get drawn, but that one had huge + EV. Then I got stuck there for 2 days because of the snowstorm that kept everyone else away in the first place.

In terms of games, I don't think they realized what they were doing, but 2 julys ago the same casino ran 3 overlapping BJ promos: suited BJs for drawing entries, 2:1 BJs during sunday baseball games, and BJ bingo with relatively achievable and very generous freeplay prizes (spaces for each suited BJ, 5 card charlie, 6 card charlie, 777, 678, etc.)

So how big was your advantage (percentage wise) would you estimate on those occasions?

There was a casino-wide "guaranteed to hit by $50,000" slock progressive promotion going on at an indian casino. The odds go up as the total inches closer to $50,000. The previous times I'd seen a winner promoted they had won between 35 and 45k. I was told that each spin basically any machine in the place had an equal chance of landing it (penny or dollar machines = same shot at winning per pull).

I was there at 4:15am on weeknight playing blackjack by myself with about 10 other people in the whole place playing slots. I notice that the progressive was at $49,550. It goes up by the amount played and the time elapsed. In this case it seemed to be going up by about a cent per $20 players. I decided to ride it out--- I mean it is going to hit before noon.

I played a penny machine pretty rapidly because each pull gives you a shot (any pull=same chance I was told). So I was playing one cent rapidly on two machines. Dropped about $50. I think it was massively EV+.

Guy on a nickel bank two rows over hit it at 5:30am for $49,6xx. I was too disgusted to stay and watch after he nailed it.

Yesterday, I got to play with a Mississippi Stud dealer consistently flashing the river. SCORE! Unfortunately, my girlfriend is now addicted to this game (flashing dealer or not) and I have to drag her away from it.

Did you use cover play at all? Or did you play with the full 90%+?

You lucky bastard :)

How do they manage to flash the river? Is it the bottom card? At most places the bottom card is the first card flipped.

No cover. The dealer didn't last long at the table. Situations where cover would be needed were rare.

So could anybody find a 200%+ player advantage at any point? I wanted this thread to be a competition. Could you expect a 500%+ player advantage (not return) to be one of the highest in gambling history?
