Thanks Dooglus for helping to explain the statistics.

hiltonizer - We'd be happy to provide you a full hand history of all your Roulette gameplay (in total, it looks like you've played 7110 spins of Roulette.). Just reach out to our support team (https://bitzino.com/support), and we'll be happy to email you a CSV.

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

What system are you referring to?


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


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.


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"


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.


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


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.


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.


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. 

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

I have to say I'm not a fan of the new affiliate system.. because it's so easy to gamble with it and lose

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.

You can hook up a mouse to Android devices. They even make custom hardware specifically for Android, eg: http://www.amazon.com/Logitech-Tablet-Mouse-Android-910-002626/dp/B0058SRNZ4. I believe that any bluetooth mouse will work.

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?

Using a tablet (or worse, mobile) the touch is sensitive -- and oftentimes instead of registering as a click [Edit: I think "touch" is the Andrid equivalent for click] the Android event is interpreted as a scoll operation [Edit: or a drag operation maybe?].

If there were some extenal device which has a single button, "click" for spinning the slots, that would be a useful device.

Does connecting up a gamepad to a tablet (e.g., Nexus 7) enable the ability for someone to bypass the touch and instead treat the button presses as keystroke entries (specifically, whatever is needed for the Spin operation?)

We've pushed an update which should fix the issues you mentioned Dooglus: We added a 30 second timeout to the cash out action, so you'll at least get some indication that your network is having issues. We also made all text on tables unselectable except for your deposit address and your bet amounts.

I also want to give a shoutout to coinad.com. Carlos from coinad emailed us to let us know about a lot of minor spelling and grammar errors that were live on our site, which we are very thankful for!

I'm glad my crappy satellite internet connection is good for something. 


I was playing some blackjack when it appeared in my account.  It confused me for a while why my balance was non-zero when I had already brought everything to the table with me.

Thanks for the comp!

Good catch! You're always helping catch the issues that arise due to network timeout corner cases, thanks! We'll work on making this time-out correctly in the same way as our other buttons.


Thanks for the kind words!


I do not know of any casinos specifically that are rigged.


Thanks, we got the message and responded, hopefully to your satisfaction


We do disable some text selection, but it probably makes sense to disable almost everything except for the text that should be selectable. We experimented in the past with making it all un-selectable, but found that bad for some of the text. We'll work to make this better so that your situation doesn't happen again.

Thanks for the bug reports Dooglus! I've added another quarter BTC to your account to thank you for helping out.

I was just rapidly clicking the 1/2 button over and over to reduce my bet back down to 1, when I somehow accidentally selected a bunch of the page.  It looks kind of ugly:



I've seen sites before disable the ability to select text on a page.  Maybe that would be a good idea for most of your games too.  I'd like to be able to select text in textboxes, but not the action buttons, etc.

Edit: I clicked 'bet', and it didn't clear the selection.  It made it worse if anything:

Emailed you about a glitch or something the blackjack game had when I was playing.

What are some of the software you believe to be rigged so to speak? I would say a lot of the online casinos in sportsbooks are rigged. I mean some claim to offer 100.5% payouts (5dimes on fridays).

The problem with that is you make the people who's down more than that sad

Customer service on this site is absolutely incredible. They've comped me a couple times when theres been issues, 1 time when they really shouldn't have, and I won some money back with it. Best online casino I've played at, cash and bitcoin.

Sorry for bumping your thread back onto the first page of the gambling forum again - I know you hate the publicity - but I found another little issue:

I had a stray half a uBTC in my account, and wanted to win another half to tidy things up.  I know, kind of OCD, but there you go.

I got the blackjack I needed, and hit 'cash out'.  Then nothing happened, and continued to happen for 10 minutes.  The 'cash out' button is transparent, showing that it has been clicked, but I guess the network connection timed out or something, and there's no script in place to notice that it happened, so it just hangs.



I just tried clicking 'cash out' again, and it worked this time, even though the transparency of the button suggests that it's inactive.

and thanks for the quarter, and for fixing it.


That's a good idea.  /r/bitcoin has been increasing its membership pretty rapidly in recent weeks.

Thanks for noticing this! I guess I mostly used the up and down arrows to change my bets while testing it, so I never noticed this bad behavior. We've fixed it now, and I've added another quarter BTC bonus to your account. Keep the bug reports coming!


Thanks for the tip! We actually did have our update function bound to keyup, but it looks like getting the value of a textbox from a function bound to keyup sometimes will return the old value of the textbox, rather than the new value. We solved this by wrapping our callback function inside a window.setTimeout, which consistently allows the new textbox values to be accessed.


Thanks for spreading the word! I've been thinking of doing an AMA about us on /r/bitcoin at some point.

I'm sure it'll take him less than 5 minutes to fix it - he probably just didn't notice it was an issue, or it only happens on Chromium in Ubuntu or some such...
