It was 20th December - Today's the third day. , right after winnings were not credited. I went to round history to check it, but it was missing. I provided this info to support right after it happened.
Sadly, I couldn't screenshot my betting on the black (Since the next round started immediately, and I was focused on winnings not credited). No data about it is also shown in bet history, so duelbits can deny the claim by saying I placed the wager on red (If they're concerned about hiding the mistake, I don't think it should be the case here).

Let us see how it turns out.

They mention the bet can be verfied through external javascript compiler (They provide the code you have to use)-
For roulette: you have to input - round id, seed unhashed (after certain hours and roulette rounds seed for those rounds gets decrypted and you can verify any round occured in that seed’ phase)
Even in history what color you picked is not shown, only Amount (won/lost), and number of bets plus the amount.

Code to verify round's outcome - Source link

This is roulette specific, I didn’t had to check for others games for I am not sure about those.

Edit: This is how it looks in history:

Yes it's of betting history, I've boxed 3 Bets made in that round. Yes the player's selection for that round isn't there (It can only be checked in real time when you make a bet during that round, idk why they don't mention the player's selection)

It doesn't show any +amount, only gray color -2.0, -2.0, -28.79 (Even though my selections were black, and the round's outcome was black) Idk why I didn't won and why the round ID went missing from roulette's history. I could be intentionally done, If there were nefarious reasons behind it then imagine if there are 2000 rounds daily and 20 of which went missing, people who weren't paying attention can't even file the complaint, even if they managed to complain then support will tell them it's a losing bet (Like how I was told, supports don't know what color player picked... only amount is shown to them)

The thing is: If the round ID goes missing from history and your account's history is showing "-amount" for the placed bet, then how would you verify the fairness? Even in real-time, suppose you placed the bet on Black, and the result was Black, but you didn't get credited for the win.
When you verify that round id, it will show the number was Black for that round, but there will be no way for you to tell you placed bet on Black (Unless you're video recording your whole betting session)



You have to wait for the next day before you can verify your round's number (Next day is when the server seed gets unhashed); you can match the color from the roulette's UI later.

Fairness link: https://duelbits.com/en/fairness
- Go to the Roulette section or search "Roulette" on that page.
- Search will take you to that section quickly.
- The first Server seed which is shown in Color red (It's encrypted because current rounds that are taking place are using it) - Once all the rounds are finished, then this red Server seed will be decrypted. Anyone can verify any round number using that Server seed.

A public node js code compiler: https://onecompiler.com/nodejs

Yes, I've input the verification code into the NodeJs compiler link quoted below; you can check it and verify the output is Number 9 for the round's ID, and its Color is Black on the table.

Regarding the credit for the lost amount, I've not received any message from the support team yet.

I see. I'll mark this as active on my list, but unfortunately that is the extent of what I can do right now. I've been reaching them for two other active cases, trying to get them back to the forum, but I am yet to hear a reply about any of the two. I have an intention to reach the staff I am in touch with again, to inquire about that two cases as well as to inform them about this one, but with these long holidays looming, I think the best step right now will be to wait.

I'll try them again, come Friday. Do you mind to update me if your case happen to be resolved before that day, so I'll know what to write to them?

Hi, have you managed to get your issue resolved? I finally got a reply with a duelbits representative today regarding the other two active cases against them. If your situation has not been resolved, I think I can try to reach them and get them to look into yours too.

Quite sad that a pretty much clear cut case cannot be resolved. I mean, what else is there to discuss and "investigate". The player made bets and the main one won, it's all in the history (kind of). Sure, we are not talking about a big amount here so obviously there is no intentional scam or anything. Yet the way they treat is case is quite sad. Worst thing is, how can you guarantee this doesn't happen all the time? Many gamblers make countless quick bets in a row, without checking the balance or anything in between because they trust that their winnings get automatically credited to their balance. Also, normally nobody is really looking through their history when they make many bets, so nobody would see that bet IDs are missing. That's quite alarming and might hint toward a bigger problem here. I honestly doubt this is a 1 time incident.

Ah, that could explain why devs were not checking around 20,21 December, but still someone is needed to keep the website in check, so someone must be maintaining the backend even at that time, those dev not having complete access to the roulette's history and code could explain why they were not checking or not able to...

But still, I don't understand why the round disappeared from the round history; I don't remember the exact number, but I am sure I saw other users made their bets on black as well during that round. There might also be other complaints if they were paying attention to the round's result; otherwise, there's no way for them even to complain; this is a serious issue for the roulette players on the site.

Let's wait and see what we'll hear.

I sent couple of messages to their support since a few days back but i hear only one thing “I will be contacted”


@holydarkness could you please list this thread into your accusation database thread against casinos.

I don’t want to sound like I am extorting them but I believe i should be compensated for my time, and witnessing this intentional/un-intentional bug.

Does it sound like I am trying to extort duelbits for it? I couldn’t even make this claim if I didn’t screenshot the bet and round history.
