Okay i just tried the 5Dimes casino online because they have pretty good blackjack games (House edge under 0.1%) but unfortunately, my little trip didn't go so well
Here are the data of my last session:
Hands: 576
Sum of original bets: 1150$
Sum of Final bet (due to double and splits): 1258$
Gain/losses: -95$
Payout %: 92.45% !!
The game i played in order to gain the deposit bonus was a 1 deck game, stand all 17, double 9-11, split to 4 hands, no double after split and late surrender on dealer's 10 only. According to the wizard of odds and his list of rule variations, the house edge is a tiny 0.11%
I used the whole way a 2$ bet size (sometimes 1 or 4 but nothing over, no big donkwager) with the optimal strategy for this game and i hit this unbelievable variance . is this usual? i don't think we can lose that much easily on a blackjack session where the house has a so tiny edge .
To confirm my though, i went to the wizard of odds website and i found in the appendix 4, details on the standard deviation in blackjack, that the odds of losing 47 units of wager by badluck over 500-600 hands was a bit less than 5% chance.
Right after that session i was quite frustrated by the variance, so i decided to take a break, but i quickly changed my mind and told myself that the odds had to change somehow (stupid i agree). So here i am playing another game, the 5deck bonus blackjack with the folowing set of rules:
After each hand played, a new 5 deck shoe is shuffled and dealt. Player blackjack is automatic winner. Blackjack pays 3/2. Dealer stands on soft 17. Double down on all 2-card combinations, even after splits. Split pairs up to 3 times. May split aces once. Late surrender available, even after splits. Insurance pays 9/4. Seven Card Charlie is automatic winner.
These rules gives an house edge of exacly 0%, but this is obviously not the result i got. Again, i lost a little more than 150$ under aproximately the same amount of time and hands and i have the data to support it. I asked in the live chat to send me the history of all hand i played, and all i need to do now is to compute them to have a pretty solid proof that this site is totally rigged. Yesterday, i also had a similar session at that same website, so that's a 3rd one .
By the time i play here, i deposited in total 500$ + around 100$ of bonus and right now i stand with a poor 100$ in my bankroll and everything happened under around 3k hands of blackjack, if not less. Using my usual 2$ bet, that's a total of 250 unit of wager lost in about 3k hands, wich has less than 0.01% chance to occur.
My plan is actually to compute the full hand history data and give the probability of this event happening, and then talk to a manager and try to claim my money back, but before doing that, i want all the chances on my side so do you guys have any tips to give me? does all this sounds unfair to you? Because maybe it's just me and my results are totaly fair . ?!?
Thanks for your reply!

I agree, it's about variance and i want to know if it's usual to get that kind of variance 3 times in a row

i edited my first post and added this info:

it doesn't really seems to stop . the chances that this event occur really makes me think that there is something wrong out there

To err is human. To air is Jordan. To arrr is pirate.

This has to be an interesting point here. I just hoped that things would have been good and well, and also by having a lot of good things to do when going to another online casino in the future.

I dunno, guys. I use 5Dimes for sports for maybe $500/day. Data indicates they're among the biggest books on the planet. Would they get that big bilking a couple bills here and there? I lose money at their casino. But I doubt they're purposely cheating me. Variance is a bitch.

It's not whether you win or lose; it's whether or not you had a good bet.
