NineWin Casino - Player’s account is closed amid claims of manipulated gaming.

I am filing this complaint against Ninewin Casino due to unfair gaming practices and technical manipulations. My total losses are much higher than the amount I initially requested as a settlement. I previously offered to settle for £1,000 as a gesture of goodwill, but given the casino's dismissive attitude, I am now seeking a full investigation into my total losses.

Specifically, in the 'Gates of Olympus' game, every time I started to win, the system forcefully logged me out with a 'Please log in' error. Furthermore, after I achieved significant wins on Roulette, the casino completely removed the game from their website to prevent me from winning further.

The casino offered me a £500 bonus to drop the case, which is insulting considering the thousands of pounds I have lost due to these technical 'errors'. Their email response hides behind 'RNG' excuses and ignores the systematic kicks I experienced. I demand a full refund of my deposits and fair compensation for these manipulated gaming sessions.

"I have increased my claim to £20,000 because, following my formal complaint, the casino has now blocked my account, preventing me from accessing my history and funds. This retaliatory action, combined with the technical manipulations I experienced and the psychological stress caused by their VIP management's constant deflections, justifies a higher compensation for my total losses and unfair treatment.

have many more screenshots and chat logs regarding this dispute, but I could only upload a limited number due to the attachment limit. Please let me know if you need further evidence, and I will be happy to provide all remaining documents via email or other means."

Dear GamerTurk2024,

Thank you very much for submitting your complaint. I’m sorry to hear about your problem. Could you please forward any supporting evidence, such as screenshots or videos, possibly your game history with the exact time of the incident along with any relevant communication to attila.g@casino.guru? Have you stopped playing right after the incident?

Meanwhile, please check our article explaining "How slot machines are programmed" https://casino.guru/how-slot-machines-work-math#how-are-slot-machines-programmed and maybe it’ll help to understand how servers communicate with players and what issues might occur on the way. Please understand that without any supporting evidence, we can’t proceed further with this case as it would be close to impossible to confront the casino.

Looking forward to hearing from you. Thank you in advance for your understanding.

Best regards,

Attila

Dear GamerTurk2024,

We are extending the timer by 7 days. Please, be aware that in case you fail to respond in the given time frame or don’t require any further assistance, we will reject the complaint.

Thank you for your response. As requested, I am providing comprehensive evidence regarding my dispute with Ninewin Casino. The evidence I am attaching clearly demonstrates that this is not a simple "technical glitch," but a systematic manipulation and a total failure of regulatory compliance.

1. Systematic Gaming Manipulation (Visual Evidence attached):

I am attaching screenshots showing the exact moment of the incident. You will see an "Error: Please log in" message appearing specifically during high-win potential moments (Bonus rounds/Free spins). The casino claims no errors were found, but my visual evidence proves otherwise. Furthermore, following a significant win on Roulette, the game was immediately removed from the platform for my account, which is a clear sign of targeting successful players.

2. Financial Irregularities & Shadow Payments:

I have attached my deposit receipts. You will notice that the payments were not made to "Ninewin Casino," but to various unrelated third-party names like "Lia Cosm," "Wandf," and others. This raises serious concerns about the casino's transparency and financial integrity.

3. Gross Violation of "Responsible Gambling" & "Source of Funds" (SOF):

Despite my total losses reaching thousands of pounds, the casino never conducted a "Source of Funds" check. They allowed me to deposit vast amounts through these suspicious third-party accounts without once questioning my financial well-being or the origin of the funds. This is a severe breach of international gambling license standards (AML/KYC/Social Responsibility).

4. Admission of Fault via Settlement Offers:

The casino’s VIP management (Phil) repeatedly contacted me via WhatsApp (logs attached) offering "goodwill" bonuses of £200 and £500 to drop the case. If there were truly "no errors" as they claim in their emails, they would not be offering such high amounts as a bribe to stay quiet. I have rejected these insulting offers as they do not cover my actual losses caused by their manipulated system.

Conclusion:

Due to the technical manipulations, the psychological stress caused by their evasive VIP management, and the clear violation of gambling regulations, I have increased my claim to £20,000. I expect a full investigation into these "glitches" that only seem to occur during winning sessions.

I am happy to provide further logs or video evidence if needed.

Also, I wanted to ask: I actually sent you two emails on May 15th containing all these screenshots and details. Could you please check if they ended up in your spam folder, or if there was a delivery failure? I want to make sure you didn't miss anything and that our future communication goes through smoothly.

Thank you for your response. I can confirm that I have received your emails.

In order for me to properly asses the issue, could you please share your complete game history? I suggest requesting the complete game history directly from the casino in Excel format. The game history should cover the whole of the relevant period where the alleged violations occurred.

As to the other issue, I am sorry, but we don't consider such features mandatory in online casinos, and we won't be able to pursue a refund request just based on the fact that you made multiple deposits in short succession.

Thank you in advance for your reply.

Dear Attila,

Due to system limitations on the complaint panel, I am submitting my evidence in batches. Please consider all screenshots (image_21 to image_33) as a comprehensive set.

These records prove:

1 Consistent returns lower than my bet sums.

2 The technical inconsistencies and manipulations I have claimed.

3 That the casino's defense of 'no technical error' is inaccurate.

Furthermore, I must highlight critical issues:

 Log Out/Freeze Manipulation: Especially when playing with real money, the system frequently forced me to log out or froze my account. This is clear evidence that the game is manipulated to interrupt play when I have the potential to win.

 Game List Manipulation (Targeted Intervention): The only game I played and consistently won on, 'American Roulette,' was deliberately removed from the platform specifically for my account after I began a winning streak. This is not a coincidence; it is a personalized manipulation strategy aimed at preventing my earnings. Instead, the casino pushed me toward loss-inducing games through targeted bonuses.

In addition, despite the significant total amount I deposited, the casino management performed no 'Source of Funds' verification, demonstrating negligence in KYC/AML obligations.

Therefore, I kindly request that you proceed with the evaluation based on all the evidence provided, including these operational failures, and conclude the complaint regarding my financial losses."

Dear Attila,

The screenshots I provided (image_21 - image_33) are an exact reflection of my account history. However, to further strengthen my case, I kindly request that you formally ask the casino to provide my full game transaction history for the date of April 28, 2026, in an Excel or PDF format. If the casino fails to provide this document or if their records contradict mine, it will serve as further proof that their system lacks transparency."

Dear GamerTurk2024,

Unfortunately, at the moment, we do not have any evidence of the incident itself (such as your complete game history in excel format showing the interrupted play, or a video recording of the incident).

Without any supporting documentation, it would be extremely difficult for us to approach the casino and request an investigation, as we need at least some verifiable information about the session in question. If you are able to obtain anything relevant, please forward it to me, and we will gladly review it and determine whether we can proceed with the case.

However, if no clear evidence of the technical issue can be provided, we may unfortunately have to reject the complaint due to insufficient information.

As to your claim that the returns were consistently lower than your bet sums, we cannot make a case solely based on what you are describing. All casino games operate under a predefined Return to Player (RTP) percentage, which ensures randomness and fairness over the long term but does not guarantee individual winnings. Short-term results can vary widely, and occasional losses or smaller wins are a normal part of gameplay. Sometimes you might get lucky and sometimes not; that's how casinos and casino games work. I would recommend reading our article about Payout ratio (RTP): https://casino.guru/learn-about-games-of-chance-rtp-variance

Thank you for your understanding, and I look forward to your reply.

Best regards,

Attila
