Incidentally, piuk made it pretty easy to offer this where you don't need to add the private key to your own wallet, ... simply supply the destination address in an API call:

Oh, good to know! In general, I prefer things that don't rely on any centralized third-parties, but this may be a good solution to get this out the door before bitcoind 0.8 is released. We'll look into this.

It's been a while since I bumped this thread, and I just noticed something that kind of bugged me, so here goes:

I played some roulette, won, cashed out, requested a BTC withdrawal, and then noticed I had forgotten to check the 'provably fair' data for my last spin.

So I bought back into the roulette table hoping to be able to copy/paste the 'last spin' data, but all the fields under 'last spin' were blank.

How about remembering the last spin data between sessions?  I'm guessing that cashing out and buying back in is what is causing the fields to be cleared.

In this case I don't really care, since I won on my last spin anyway, but in general I would like the last spin data to be available until after my next spin...

[dooglus]

Oh, and since I'm here...

I just deposited, played a little, and then withdrew.

The withdrawal is pending since my deposit didn't confirm yet.

It occurred to me that you could use the same strategy as SatoshiDice, and allow instant withdrawals by using my unconfirmed deposit as one of the inputs to the withdrawal transaction.  That way if my deposit turns out to be a double-spend and so never confirms, neither will the withdrawal.  (Since transactions can't be confirmed unless all their inputs are also confirmed).

That way you can allow instant yet risk-free withdrawals, even for people whose deposits haven't yet confirmed.

Every once in a while I get a little chuckle out of this thread. I love your attitude, lib. I'm constantly amazed that you haven't lost your cool yet.

Yeah, surely by now you want to start telling me that my girlfriend is imaginary and banning me and all my friends from playing at your site even though I've never broken any of your terms and conditions.  That seems like the obvious thing to do.

I'm amazed you can take so much free constructive criticism from me without flying off the handle in a drunken rage.

It's almost as if you're running a professional operation or something.  

Edit: oops.  I forgot why I came back here.  I was just playing with the 2-factor authentification.  It works well, but I can still log in and lose my balance with just my regular password.  It would be nice to have an option for whether the 2-factor auth is required only for withdrawal and changing security settings, or for every login.  For me, having an attacker lose my balance to the house would be just as upsetting as having them withdraw it to their own address.

Bug report -

I was playing blackjack for 100 millibitcoins per hand and was dealt an 11 vs dealer's 9 (I think?). I doubled, hit 21 and won the hand. I clicked cashout and it would not let me cash out. So I bet 1 millibitcoin and lost the next hand and it let me cash out.

I also think your craps game was rolling two hands at once or doing something crazy. It happened fast, but it looked like I won my don't pass odds bet as well as the bet I had an don't come at the same time. I could be wrong because the animations were happening pretty fast.

Thanks Frankly, I'm constantly amazed at how supportive the bitcoin community is. That's something I wasn't really expecting when we first launched, but it has proved to be an incredible asset. Everyone here believes in the transformation power of bitcoin, which I think really helps create a positive environment.

I'm going to stay out of this, but I will say that I respect you both highly, and I really do hope you can resolve your differences.

We hadn't really considered the possibility of your attacker just being spiteful when we first built this You raise a good point though - we'll add an extra option to require the OTP for logging in as well.

I believe this was a temporary issue that we introduced, and should be fixed now. Sorry about that! What's your bitZino account name? I'll comp you some BTC to make up for this.

Hmm, I doubt that it was actually playing 2 hands at once, because our backend system would completely disallow that. However, it may have been an animation glitch. We'll keep an eye out for this! Also please let me know if you find a way to replicate it

We've added the option to require 2-factor auth when logging in. Thanks for the feedback!

Thanks, but it's a day too late.  It looks like an attacker got into my account yesterday and lost my whole balance.  It looks like he played a dumb martingale strategy on roulette and hit 10 blacks in a row.

Yeah, that's probably what happened alright...

Hmm, I've got errors about it being open in another window or something frequently when I was playing on my iPhone over 3G. When I logged into my laptop and stopped playing it on my iPhone, same problem. Couldn't play / bet blackjack at all. Is this a known issue with accessing it from mobile browsers?

It looks like the attacker came from your IP address. Are you sure that the attacker didn't break into your home specifically to play on bitZino under your account? You may want to beef up your physical security

Hm, I can't seem to replicate this issue. I just tested it out on my ipod touch, and it worked correctly for me.

That error will show up if you leave a browser window open, and go on to play the same game in another window or on another computer, and then come back to the original game and try to play (Basically, anytime your game is out of sync). You can ensure that error never happens by just refreshing the page before you start a new session. Also, the error should cause the page to refresh, so it should happen at most once.

We did have a buggy release live for a few hours the other day, and you may have been affected by it. Would you mind testing again if you get a chance?

What's the odds of 10 in a row? I was doing good until that run of bad luck hit and wiped me out.

If each spin was 50/50, it would be 1023 to 1 against getting 10 reds in a row.

Code:

>>> 2**10 - 1
1023

But there's a green too, so it's 1345.8 to 1 against.

Code:

>>> (37/18.0)**10 - 1
1345.7661421344362

I've seen it happen twice and I've played a lot less than 1000 spins.

[dooglus]

Thanks, maybe I should stretch my go broke point out to 15 plays or so.

The problem then is that you can't bet more than 0.00061 BTC on your first bet, or you'll hit the house limit of 10 BTC before your 15th play.  So you'll only be 'earning' 0.00061 BTC each time you spin a red, and it will take you forever to earn just 1 BTC.

Code:

>>> 0.5**15 * 20
0.0006103515625

I figured I'd round out the all-red and all-black screenshots with an all-green one.

Note that this screenshot is totally fake though You'd probably have a better chance of mining a block with a vacuum-tube CPU than ever seeing this happen.

[libertaad]

I've seen it happen twice and I've played a lot less than 1000 spins.

I often come up against runs of the same colour, but usually they max out around 8 in a row. Twice I have hit 10 and been eaten up.
To be fair, I probably spun about 5000 times. How it goes I guess. Ah well, still not down as much on roulette as I am on SD lol.

If you guys are interested, I'd be happy to send you CSVs of your spin history so you can do some deeper statistical analysis. Dooglus, looking at your account, it looks like you've actually played 1244 roulette spins

1244 spins at Roulette! What a degenerate!

Any chance of making slots? I think I remember seeing someone else trying a provably fair slot setup in here somewheres, I would be a happy camper if bitzino offered it.

His slots game was weird.  Instead of picking 5 numbers to decide where each of the 5 wheels would stop, he picked 15 numbers to determine all 15 visible symbols.  Real slots don't have the symbols on the wheels rearrange themselves at random like that.

Oh, and I don't think I need to see a log of my roulette spins, thanks.
