Hi Doog... Thank you for founding those problem! Edit3: I think the problem is that when the payout multiplier is fixed, and you calculate the chance from it, you're rounding up instead of down, giving a slightly lower house edge than intended, which the server then rejects. When I'm trying to bet 0.04 to win 2x, the chance is set to 49.662%, but if I put 49.662% in the chance box, the payout is a little under 2x. I ended up editing the chance to 49.661%, the payout went a little over 2x, and it let me bet. I suspect you can fix this by rounding down instead of up when calculating the chance from the payout multiplier.
That's very good observation. It does related to rounding but not exactly because of round down / up problem. It is because the server reject an unavailable payout. Here's our explanation. - When the user manually set the payout, browser will round the payout to the nearest possible payout (because roll number / win chance is actually a discrete number) after the user is done editing
- With variable H.E. the payout can change in realtime. When the H.E. changed, browser changes the win change according to the user payout.
- However, the payout still remain the same, and those exact payout doesn't always available (remember that roll number is discrete).
- When the user rolls, SD's server check the roll integrity and found that the submitted payout slightly missed, therefore the safety mechanism rejects the roll (our log literally wrote "impossible payout"
 ).
We have fixed this issue now, the payout will now change to the nearest possible payout automatically when the H.E. changed. Is there a bug bounty on this site? If so, please credit it to my on-site balance.  Done! We don't have a bug bounty program, but may reward it in an ad hoc manner. Many thanks for all the reports and suggestions so far Doog Edit4: The variable house edge feature works pretty well (other than the error I reported above). Here's a screenshot showing how the site got me betting against a 5% house edge - something I would normally never even consider doing. Lol, luckily you won those bet |

you should add faucet
it will attract a lot of people!!!
IMO their bankroll is much too small to support a faucet. The max bet for what their bankroll (~11 BTC currently) can support is only a little bit larger then what faucets would give out. Plus you have the issue of the fact that the bankroll is investor funded An alternate suggestion would be to allow people to play with "play" money that cannot be withdrawn and is kept track of separately then real bitcoin deposited. this also a good suggestion because there are dice sites that has no faucet but was able to get supportive members But wouldn't that will be confusing for the player? It's like integrating test server and real server at the same time. |

Thank you for the suggestion pure, but there are also lot of controversy about faucet. Currently we are still trying to attract people with features other than faucet. What controversy is that? This one...  how about you add faucet for a few days so we can test the site Faucet is important so that we can try the site out. faucet invites bot users thus makes the site slower and some beggars that spam. |

Someone might have asked this before, but I am wondering this: Why is the house edge 2% if I want to make a bet of 0.06 @ x2 ? If I bet 0.15 @x2 the house edge is 3%  Why is that? Hope this explains SafeDice is using a variable house edge. By default, the house edge is 1% with a max win of 0.5% of the bankroll. Players can also have a higher max win with a bigger house edge, for instance, under a house edge of 2% there will be a max win of 1% of the bankroll. Yeah, that explains a lot. I didn't read the previous pages. In the next update the house edge will use a floating number, stay tuned guys |

Nov 19, 2014 - Investment feature will be disabled in the next updateFollowing our recent discussion with some forum members. We think it is best to close our investment feature until indefinite amount of time. We admit that currently we are still to new for this type of feature and the community just get shocked by the recent cases. Continuing this feature will not only harm our brand, but it might implied that we are insensitive to the recent cases. - Will you open this feature again?
We might open the investment feature again in the future when we work with a partner that is trusted both by us and the community, or when we believe we are ready and there are lot of requests of this features. - I still have investment in my account, what should I do?
If you still have your investment in your account, you will still be able to use it. - But will the site be playable?
We will use our Variable House Edge system, this will allow us to run the site with lower amount of bankroll to a certain limitation. Meanwhile we are looking for a better solution. - But I really want to invest?
You will need to contact us privately for this matter.

So does it means that if I bet 50 %
Because of 1 % house edge
I got 49% chance for winning that bet ?
No, you have a 50% chance of winning a 50% bet, but when you win, you don't get 2x your bet, you only get 1.98x. 1.98 is 99% of 2 If you bet 1 unit at 50% 2 million times, you will win about a million times, and lose about a million times. Each loss costs you 1 unit. Each win nets you 0.98 units of profit. Your total losses are 1 million. Your total wins are 980 thousand. Your net loss is 20 thousand, and your total amount risked is 2 million. Your net loss (20k) is 1% of your total risked (2 million). Get it? Got it Thanks for the awesome explanation. Now I know the 1% edge risk Thanks for helping to explain Doog  |

Can you do a leaderboard for the top players who waged alot.
For what purpose? Does the site have affilitiate program like Win88 too? Leaderboard is fun, when we play a multiplayer game, we tend to pursue the number one ranking didn't we? . Currently we are focusing on the development of variable house edge, and then we will focus on functional features and features for our investors first. But additional things like leaderboard is also on our list Currently we don't have an affiliate program Marykris By the way, here's a screenshot of our recent works (not published yet), a variable house edge that can change depends on the 'profit on win'!
So, a bet with lower "profit on win" will have a lower house edge, and vice versa? That would make your site very attractive to smaller gamblers with the lower edge. Exactly!! And still safe for the investors too |

I have withdraw 0.1788 but site wa laggy did not withdraw for me, then i played again and withdraw 0.1905 and i did not recieve
just recieved 0.1788
please check my account
nick: Azmy
Hey Azmy, finally, congratulation for the winning! I'm confused with your statement, but I guess you already received your withdrawal? Your 0.1905 withdrawal was not being processed because actually the previous withdrawal had been processed immediately and you don't have enough balance for the second withdrawal (here is your 0.1788 withdrawal tx log http://btc.blockr.io/tx/info/30573f90c7c5240c66b2d4a20c9c1d4b080e1e3e8b74a19a4be676a4edf758d7) and i think there is a bug, you said max profit 0.05.
i bet 0.0001 x 980 and wont almost 0.097 btc
check
i dont think thats a bug, since you can aim for a higher max profit if youre willing to deal with a increasing house edge. at least thats the way I understood the explanation in this thread somehwere above. Yes, exactly. You should also able to check the H.E. that is being used on the bottom of the betting box. I had enought balance, i had 0.1788 and then withdraw but could not withdraw so i played and won more 0.02 and then withdraw 0.19 but did not recieve also, just recieved the first one. I just saying because there is a lag or bug which caused that and i need you to fix it, i do not need anything else. Just advice I like the site anyway I think that's only a connection problem, everything is ok in our log. Ok then, as long as you already received your 0.1788. We will keep an eye on this, don't hesitate to let us know when you encounter this again. ----- By the way, here's a screenshot of our recent works (not published yet), a variable house edge that can change depends on the 'profit on win'!  And yes that's a roll with 0.64273389% H.E. |

Had we not known Mark Karpeles' information matters would be much, much worse.
Agree. But what I want to say is that knowing the owners' info may help a bit in gaining trust, but the effect won't be enough IMO. On the other hand, having doog control (or co-control) the server seeds and cold wallet could work IMO.
Yet that defeats the purpose of gaining trust or even setting up a gambling site if a reputable member comes in and pretty much takes over (sever seeds and cold wallet funds are the things which show ownership and control). Actually, involving dooglus just makes him run another gambling site, instead of Sam.Walton runnning a new one. Yup you are right. Maybe you could even call the site JD 2 then. I guess it depends on what OP wants. If he wants to make himself and his site trusted, it will be a slow and costly process. If he simply wants to make his site trusted and earn some bitcoin through running it, partnering with a trusted bitcoiner (and sharing part of the site profit) could be a much easier and faster way to do it. Exactly, that will be the options that we are considering, another option is to run the site with our own fund as bankroll (but of course we'll have to find another source of fund , which is challenging as well). We are pretty much open for certain possibilities at the moment.. Lets see how this will go. This is very exciting moment for SafeDice. Also, whichever decision will we take, we will need to improve the site features and usability, so that will be our focus in parallel. Why is doog not replying safedice's messages?
Messages? Do you mean in this thread? |

I suggest the following: Sam.Walton why don't you provide your personal information directly to dooglus? I understand that you wouldn't want too (and you have absolutely no obligation to do so), however this would improve community trust in you ten fold, once dooglus verifies the information. Otherwise, you could involve dooglus somehow (for example having him hold server seeds as he offered with dicebitco.in). Once again, you have no obligation to do any of the above.
Thanks for the suggestion marco. We will explore these ideas as well |

And Doog, if you have the time, would you be interested to test this new feature when it is finished, but before it launches to the public?
Everytime same thing is happenning. I can imagine after this: Sam.Walton : Doog tested our site, we are trustable, good, fair, we won't run with investors money when reach to xxx btc. Come to us! And then one night run away. Simple. UI is good but isn't giving any confidence. Maybe it's just a hoodwink? I don't like your anonymity. We were asking dooglus for help simply because we take him as our hero, I think a lot of other people appreciate and admire him as we do. When dooglus replied our thread, we were not just excited, but were determined to not disappoint people like other bad examples. We think that if we can be as successful as JD, we can have a very decent incoming without being cursed, and no one wants to be cursed because of stealing people's money. It's not cool. We also believe that, a sustainable dice site is helpful to the bitcoin community, we are believers but now speculators of bitcoin, and don't want to do anything bad to it. For the anonymity, please understand that, we do that for the safety reason, we'll also provide the best anonymity for our players, that's why there's an onion address for the site. To build the reputation takes a long time, and we're prepared to do it anyway. |

Sorry for I didn't think it clearly enough. Yes for a default of 0.5% max win with a 1% edge, it's impossible for a player to take the bankroll through a single bet, it only happens when the max win is 1% of bankroll under 1% edge. But the chance is just too tiny which is like a jackpot Will you be allowing investors to specify the maximum percentage of their investment that they are prepared to risk on a single roll? It's possible that some of them wouldn't want to risk 50% of their coins on a single roll no matter how high the house edge was. We don't think so Doog, it would be complicated. It's also doesn't make sense if a player bet on a super high HE, just as you said, in that case they'd be better off betting on another site with higher BR. So, our current idea is to cap the HE between 0.5% to 10%, depends on their profit on win / bankroll ratio (we'd like to keep it at half kelly). Do you think this would be a good idea? Another thing to consider is that the site will be deciding a bet's HE in real time, so if there's an invest/divestment when the bet request is sent from the client to the server, there might be a slight difference between the HE shown on the client and the server's calculation. And Doog, if you have the time, would you be interested to test this new feature when it is finished, but before it launches to the public? |

Currently, the house edge is capped at 3%, and we'll lift it to unlimited very soon, that means you can take away the whole bankroll with a single bet under a high house edge, stay tuned guys!
I don't think so: You can win 0.5% of the bank with a 1% edge, Win 1% of the bank with a 2% edge, etc. So to win 100% of the bank, the house edge would need to be 200%. percentage_chance_to_win = (100 - house_edge_percent) / payout_multiplier If the house edge goes bigger than 100%, the player's chance to win goes negative... So the most you can let a player win in a single bet is 49.99% of the bankroll. At that point, supposing they want to double their money, their chance to do so is (100 - 99.98) / 2 = 0.02/2 = 0.01%. So that's a one-in-ten-thousand chance of doubling their money. In other words, there's a point at which it becomes silly, and the player would be better off just using a site with a bigger bankroll... Sorry for I didn't think it clearly enough. Yes for a default of 0.5% max win with a 1% edge, it's impossible for a player to take the bankroll through a single bet, it only happens when the max win is 1% of bankroll under 1% edge.
