Just ask a dealer next time you're at the casino.  Ask them if the dealer wins the majority of the first hand dealt from a new shoe.  I don't know why this is, it's just the way it is.  I always bet the minimum on the first hand when playing live. 

Take a second to think about what you're saying.  The deck is shuffled randomly, both at the casino and at bitZino.  So the cards that come out on the first hand at the casino table are random cards.

Suppose you arrive at the table just after the first hand was dealt.  12 cards were used, and hundreds still remain.  The remaining cards are in a random order, just like the first 12 cards were.  Do you have any more or less chance of winning?

If you know that the first 12 cards were mostly high cards then you could say you have a lower chance of winning the 2nd hand, but that's just like saying if you knew the bottom 12 cards on the deck were mostly high then you'd have a lower chance of winning the first hand.

As you see more and more cards from the deck, you gain more and more information about the composition of the remaining cards.  But there's nothing about the top few cards of a freshly shuffled deck that make them 'unluckier' than the rest of the cards.  The dealer lets you cut the deck anywhere you like before he starts dealing anyway, so maybe it's your fault for cutting in the wrong place?

I don't know if you're going to buy that explanation.  I've been having a hard time recently trying to understand what other people are thinking.

The bottom line has it about right though: "don't gamble" (although I'd add "unless you see it as buying entertainingment, can afford it, or know how to win!")

Yeah, when you're playing live, the chances of the dealer getting 3 or more BJ's in a row are ludicrous.  But if Bitzino shuffles 8 decks before each hand it seems more probable.  When playing live, they say the dealer wins the first hand 60% of the time.  Just ask any dealer.  That, in itself, is where Bitzino BJ (and all online BJ) is favored more for the house, imho.

Lesson, don't gamble!

I play (far too) often, and I admit I have had times where I was thinking WTF?!!? Between generally losing every hand and the amount of blackjacks hit by the dealer.

Then I sit back for a second and think about how fast I am playing, and how long I am playing. If I were at a casino playing at 1/4 the speed I play on bitZino, I would be broke in minutes... Since it is easy to play fast, and there are no other players, and its a program, its easy to have doubts. About the blackjacks, I have gotten at least four, and I want to say it was five, in a row at a physical table. Statistic support or not, I know its possible.

OK, so now I understand.  Thanks.  It would have appeared unfair if you had been dealt the blackjacks too, but not the kind of unfair that players tend to complain about...

I'm sorry, let me be more clear.  The dealer had the 5 BJ's in a row. 

I still don't understand why you're complaining about winning 5 hands in a row.  It doesn't happen very often, but it happens occasionally.  You got lucky.  Sometimes the dealer will get 5 blackjacks in a row too.

Are you mixing up 'provably' and 'probably'?  They're entirely different concepts.

Gross Error. Flipping a coin 5 times has just above 3% of probability of actually getting all 5 times heads.
5 Coins with 2 possible outcomes in each (head or tails) means 2⁵, which means that there are 32 possible outcomes, with only one outcome being all 5 heads, which means 1/32= 3.125% chance of happening
And yet, it can happen; and that doesn't mean that it is unfair if you get all heads in your first trial, the actual probability is always going to be approximated with a large number of trials.
Please do me a favor and go read about Frequentism.

Full Disclaimer: I never played in bitzino, I have no stakes in bitzino, and I am not defending or advocating bitzino.
I am just saying that it is not necessarily true to call a game unfair based on very limited trials, which will always look skewed without enough sampling.

Short answer: our blackjack game uses 8 standard 52-card decks which are reshuffled before every hand.

Long answer: Every single blackjack hand played on bitZino is a fresh set of 8 decks of cards (each of the 8 decks are standard 52-card decks, thus making a blackjack deck contain 416 cards). Before each hand a fresh blackjack deck (containing 416 cards) is shuffled on bitZino's servers using a cryptographically secure random number generator. The hash of this "initial_shuffle" is then presented to you, and your browser are also asked to generate a random "client_seed" (you are also free to manually modify this client_seed). BitZino's servers then reshuffle the deck using the client_seed provided by you as the source of randomness.

This reshuffling process is what allows the game to truly be provably fair. Since our servers have no knowledge of the client_seed until the exact moment the game is starting, it is impossible for us to manipulate the outcome of any games, without making it obvious that we've done so.

I'm happy to answer any more questions about our provably fair process! We also wrote up a detailed technical blog post if you really want to get into the nitty-gritty details: https://techblog.bitzino.com/2012-06-30-provably-fair-shuffling-through-cryptography.html

Flipping a coin is a 50-50 chance.  Answer me this how are the cards dealt in blackjack on bitzino?  Is it a new deck of 52 cards every deal? 

I can toss a coin and get heads 5 times in a row, and not because of that I assume that the coin is rigged.
Immediate effects can look skewed, it is the long term what matters.
People should get a lesson in probability before playing gambling games. Read up about Frequentism.

I was trying to find a record of this occurrence in our gameplay logs, and couldn't seem to pick it out. I was only looking in a limited timeframe though, so maybe I missed it. In total, we have seen 3.5 million hands of blackjack played, so I wouldn't be surprised if this has occurred at least once within our history.

If you'd like, I'd be happy to send you a log of all your gameplay on bitZino. These logs will include all gameplay information as well as all the information required to verify they were dealt in a provably fair manner. You are welcome to verify the provably fair information as well as do any statistical analysis you'd like over the set of data!

Correction, I was dealt 5 in a row.  How can you call that fair?  Probably not fair.  Props to you my man, you're getting rich!

Aren't blackjacks good?  I don't know why you'd quit playing if you keep being lucky enough to receive blackjacks.  Or did the dealer receive them?

The odds of any two cards from 8 decks being a blackjack are 1 in 21:


So the odds of 5 sets of 2 cards all being blackjacks is that to the fifth power, or 1 in 4.2 million.

If you don't card whether it's you or the dealer who gets the blackjack, the odds drop right down to about 1 in 100 thousand hands of seeing a blackjack 5 hands in a row.

I can assure you that our games are fair. In fact, it is computationally impossible for us to manipulate the outcome of any games played at bitZino, due to the provably fair system of shuffling we use across all of your games. I encourage you to read more about it at https://bitzino.com/about/fair!

I received 5 blackjacks in a row.  3 in a row is a statistical improbability let alone 5.  I'm done playing here.

Sorry for the brief downtime earlier. We are back up and fully operational now. It appears our hosting provider had some minor issues which affected us as well. We always strive for 100% uptime, so we are looking implementing some redundancies in order to avoid this type of unexpected downtime in the future.

Yea, it's down for me too

The site went down for me in the middle of a craps round WHILE the dice were rolling.

Omg, thanks for 1 bitcoin    I love this casino
