BLACKJACK SLOT MACHINE IS IT LEGITIMATE

i am playing a blackjack slot machine in an Indian casino in California. i would like to know if my results are too far out to be legitimate.

four decks
80 card penetration then shuffle
dealer hits soft 17
BJ pays 3/2
late surrender
split pairs once, double down after splitting except aces
double down any two cards
late surrender

This game is a -0.534 loser. I do play according to the wizards strategy.

I bet 20 dollars per hand, playing 2 hands at a time ($40). since April I have put through $350,000 in action with a loss of $9,513.00. This results in losing around 2.67%. My friend who knows standard deviations says this result for so many hands (17,500) has only a 2% chance of happening. Is it possible that they have programmed to machine somehow. Please don't respond why do I play. I am still ahead because of the promotions and mailers. however, my results should be better.

sincerely

right off the bat, about 10 times EV doesnt surprise me



that's a lot of hands flat betting



Wizard has SD at 1.15 [different rules, not sure how much that matters]



sqrt [17500] * 1.15 = 1 SD by units



132.2875655532295295 * 1.15 = 152.130700386213958925 units



152.130700386213958925 * $20=$3042.6140077242791785



9513/3042.6 = approx 3.127 standard deviations



your friend is right, your luck has been pretty bad from what I get [I sometimes screw this up]. However I would not call it outrageous.



btw the forum is the proper place to ask questions, discuss things. Who knows if other, better mathematicians will see this?

Oh, the EV should be added to this and I skipped that. Probably brings it right at 3 SDs

The simple answer to your question is that the results are not 'too far out to be legitimate'. If 100 forum members played the same game as you, we would not hear a peep from 98 of them and two of them would air their suspicions. Unfortunately, you are amongst the two.....



That being said, it is of course possible that the game is rigged in some fashion, but you do not have nearly enough evidence to make that assertion.
