I think that using mBTC (milibits) and sats would be a better idea than Bits, more people are familiar with them from other betting websites.
Better remove that sign Don't hack us from top left corner, and it will motive people more to really try and hack you.

In this case, the bankroll is effectively his pocket. While his expected profit is the house edge multiplied by the bet, his actual profit depends on how the bets end up going. If he did profit 10,000 bits from a losing bet, there's nothing stopping him from taking them as profit. Expected profit is simply the expected value of each bet and doesn't represent exactly what will happen as users play bets.


Losing all of your balance doesn't mean that there's a house edge. It could very well be a result of variance, especially if the house edge is close to 0% (either positive/negative). You also had a very very small sample size.


I can't seem to find the rules used by your game of blackjack. If you know what they are, you can plug all of the values into a blackjack house edge calculator to figure out what kind of edge you have. If the set of rules is unique, your best bet might be to run a very large number of simulations to determine what your house edge is approximately.

I think you should close the project and not waste your time and money.
I don't see any point in playing in your project.
If I borrow $ 1000 and win $ 2000, I understand that I will not be able to withdraw.
I generally keep quiet about the maximum rate.

OK that's like putting a huge bullseye for hackers on your casino.


I would host this locally if it's even possible, because as I mentioned in a previous post, DNS hijacking is a real thing and can send back different validations or even hashes. Do not make a network request to that resource in production.

I noticed you posted a 50 bits promo code here just now but removed it. I'm the one that used it (I think they're still one-time use?).

I wanted to see how your bankroll would withstand a few bets so I was gambling 10 bits at a time for most hands.

As I expected, I eventually lost all that bonus money after going as high as 110 bits at one point. So it at least makes me feel better that you have some kind of house edge.

I'm not too comfortable that you set the Blackjack payout to 30 bits. I know it's rare, and a streak of losing (as in theoretically impossible to win) hands swallowed all those bits - including a 50bits bet I placed towards the end of the run after a series of 10 bits, but consider the possibility of someone striking lucky and hits blackjack getting the triple payout and immediately withdrawing.

Given that 50bits is the max bet, a 150bits win can still punch a huge hole in your [now depleted] bankroll.

I like the concept of your casino, but the bad thing is you'll be hard or impossible to get a gambling license. This make people is hard to trust your sites since there're so many thing need to be answered in public.

1. How we can sure the user ID generated on your URL is safe? is there any way to gambling?
2. Can you add 2FA before user can log in with unique code generated/UID?
3. Your slogan Hack us you mean you're pretty sure your code is secured, but why you still faced a vulnerability in your casino?

Just for information you can use this sites https://www.toolsley.com/hash.html to validate the cards hash, just copy the deck cards and you will see an exact hash on SHA256 to validate.

Based on the bet history, most bets that are higher than 100 bits were lost bets. I did not check all pages of the bets history but I can see some 10,000 bits losing bets. Shouldn't you make some profit from those 10,000 bits losing bets? That's even 3x bigger than your bankroll. Coming up to the word "hacked", is it appropriate to accuse player hack your site while there is no rules on your site about the max bet? You allow the bets and there are losing bets too, how can it be called by hacked?

Perhaps put this project on hold for the moment?

Doesn't look the best on your brand if you put out an unfinished product that can't even be used properly.

Also, I'd highly suggest that you start with a higher bankroll - 100 bit max bet is a joke, this is the base bet for a lot of players.

So the code doesn't work at all and I believe that either it was for limited accounts or was it for a single person and you'll be giving us more promo codes each in order to try out the website? BTW, what's the bankroll of the website if you don't mind sharing it? And I'm totally fine with creating an account at your website because we don't have those satoshidice kinda websites anymore where we need to store our URL to play ahead. I fear of losing the URL as well as my funds too, so please make signing up available on your website.

I was visiting your website and tried to apply the code but it seems the code is not valid so I did not expect success.

It is my first time to see a gambling site like your website because we do not have to register and only need to save the URL. It is so simple and does not take long to start playing. I can not try playing the game since I can not use the code so I think I will wait for the next code that you will share
