Ideally though, external hardware should not be necessary to play our games! We've tested our site on a handful of tablets and phones, and it does seems to work well - but we haven't tested every device. I wonder what device you are using, and do you see the same problem of "clicks registering as scrolls" on other websites as well?

Have you tested in a bar with slightly intoxicated people? 

I have ... as I umm, was performing market research.  Or something.  For science, of course.

Women who happen to have long fingernails were the ones who seemed to have the hardest time with it.

I advise against the roulette system at this time, not because I believe the operators are nefarious but because their algorithm for random numbers does not scale down to a system of this size.

As we know, any computer generated number is not truly random due to the chicken/egg problem.

While provably fair, the roulette table in my experience has not proven to be statistically fair. I do not believe this to be nefarious in nature buy as a result of poorly designed methods of generating random numbers. What I see is a star pattern in number generation.

Fortunately for the proprietor, this has to be the case given the liberal min/max limits on outside bets as they relate to any type of martingale system. Bet limits are used with and/or american style double zero tables. Broad limits and single zero tables are inherently vulnerable to martingale. Anything too good to be true, absolutely is. The rules of the table as-is would destroy the owner given that the customer base knows basic math.

Based on my average spins per minute, and a tally of of certain scenarios, I can say with confidence that the house edge on zero's is in neighborhood of 5%

Cases of color reaching 10+ streaks occur multiple times routinely 1000 spins, a statistical anomaly. The math logic on this table appears to statistically error in the low digits, so if applying any type of martingale one would be best served playing 3rds by number and not row, and certainly not by color. At any given moment, a full history will demonstrate at least 40% of numbers under 12.

Tad, if you would be interested in disputing, i've been operating under the "wallet' of 1A4ewbBxNy5Eke8LTnNUHvD4s1Rrh2qgVm

What system are you referring to?

Random numbers don't need to scale.  Is this some kind of joke?

Quote

What came first, the bitcoin casino or the mathematically challenged customer?

Is that a thing?  "star pattern"?  I'm not having any luck googling for it in the context of random number generators.

Quote
Fortunately for the proprietor, this has to be the case given the liberal min/max limits on outside bets as they relate to any type of martingale system.

If you can find any kind of a pattern in the random number generator, you should exploit it.  If there are more runs of all-red or all-black, then alternate your bets red-black-red-black and you can't possibly lose, right?  Or toss a coin before each play and bet red for heads, black for tails.  That way you've restored true randomness to the outcome and can take advantage of the site's "vulnerability to martingale"

Quote
Broad limits and single zero tables are inherently vulnerable to martingale. Anything too good to be true, absolutely is. The rules of the table as-is would destroy the owner given that the customer base knows basic math.

Martingale is a losing strategy.  Single-zero roulette has a house edge of 2.7%.  Vary your bets all you like; you won't change that.

Quote
Based on my average spins per minute, and a tally of of certain scenarios, I can say with confidence that the house edge on zero's is in neighborhood of 5%

If 2.7 is in the neighbourhood of 5% then you're right.  It's only 2.3% doors down the street.

Quote
Cases of color reaching 10+ streaks occur multiple times routinely 1000 spins, a statistical anomaly.

You're meant to see 10+ streaks of the same colour every 655 or so spins.  ((37/18)^9).  If you're seeing them every 1000 spins, you're not seeing enough of them.

Quote
The math logic on this table appears to statistically error in the low digits, so if applying any type of martingale one would be best served playing 3rds by number and not row, and certainly not by color.

The worst thing for a martingale player is an unbiased wheel.  If I know the low numbers come up more often than they should then I can exploit that and lose less than 2.7% of my bets; maybe even win, if the distribution is skewed enough.

Quote
At any given moment, a full history will demonstrate at least 40% of numbers under 12.

I'd keep quiet about that if I was you.  I certainly wouldn't "advise against the roulette system at this time".  Why not just bet over and over on the 1-12 bet?  You get paid out 2-1 for it, and win at least 40% of the time.

I just tested your theory.  I played 37 spins, betting "1st 12" each time.  I got these numbers:
  24 35 30 30 10 23 20 9 15 33 36 0 15 16 18 7 22 26 24 1 36 24 2 15 26 29 32 23 18 13 1 34 9 11 1 7 7

That's 1 zero, 11 in the 1st 12, 14 in the 2nd 12, and 11 in the 3rd 12.

Looks to me like it could be randomly distributed.  It's unlikely I'd get so few in the 1st 12 if 40% of numbers are under 12.

And I've probably just fed the troll.  Oh well.  Smiley

I'm not sure if he is trolling, or just had a loss martingale streak and thinks the game isn't statistically fair.

Thanks both.

I wasn't making note of certain stats for all 7k spins, but I may take you up on that CSV when I get home tonight and do some further analysis.

One thing I can say for certain, the real smart gamblers haven't been spinning roulette wheels but just holding btc  Cool

Questions about bitZino blackjack:

1) Does dealer peek for blackjack (American)? Or no peek (European)?

2) Does the player lose only original bet against dealer blackjack?

I am trying to calculate the house edge based on your stated rules.

Cheers,

Cheers,

The dealer does indeed peek, which means you only lose your original bet against a dealer blackjack, because you are never given the opportunity to double or split.

Thanks for pointing out that our states rules did not include this! We have added this rule to the list, so it is now clear what our rule-set is.

Thanks for the prompt reply, that is very helpful.

According to your stated rules, I have calculated the house edge to be 0.398% when using basic strategy.

Glad to help!

That's the same house-edge we get when we calculate it as well, so I'm glad we're on the same page!

What did you both use to calculate the house edge?  I'd be interested in something open source, because some sites have some very strange rules which the wizardofodds calculator doesn't know about.

We just ran monte-carlo simulations on our game in order to get a house edge. We also corroborated this number with the wizardofodds calculator.

We don't have any plans to add support for LTC right now. The main reason for this is we haven't really seen any demand from our players. I'd also be concerned about making the interface more confusing for people: it's nice to be able to show a single deposit address for players when they are getting started.

We don't have this functionality exposed, due to security concerns. Since it's possible for people to store large amounts of BTC with us, we want to be able to manually look at each password reset and ensure everything looks good. So, the typical way you can get your password reset is just by email us at our support email, via https://bitzino.com/support.

In your case, I'm happy to help you out if you just send me a PM here (in this case it will probably be easier than opening up a new support ticket).

It wasn't for my account, it was my (imaginary) girlfriend's.  She emailed your support address and got a pretty quick response.  I was just surprised not to find anything about resetting the password when she got it wrong.  Even a "please email us if you've forgotten your password" would help I think?

Good call. We'll add some more explicit messaging around this. The UI up there is a little cramped, but we'll find a way to make it work - better than having confused users.
