Miki Casino - Dobici igrača su neočekivano konfiskovani.

On April 24th, I received a 100% bonus offer, so I deposited 75,000 yen. On May 8th, I met the wagering requirements, so I applied to withdraw my winnings plus the principal of 622,000 yen, but received an email stating that I had violated the terms and conditions, and all of my winnings were confiscated, and only the principal of 75,000 yen was returned to my account. Withdrawal of 75,000 yen on May 9th

When I asked about the violation of the terms and conditions by email, I was told that it was because I was using Double Up.

There is nothing explicitly stated in the terms and conditions that prohibits the use of double-ups, and I have contacted support to explain that if you bet for a long time, you will unintentionally end up with bets like double-ups, and I have requested that the confiscation of my winnings be rescinded, but I am told that this is "the decision of the department in charge" and that "a decision once made cannot be reversed," leaving me with no solution.

All I can think is that they made rules after the fact because they had a big win and are refusing to withdraw money as a violation of the terms and conditions. I would be grateful if you could help me somehow. Thank you in advance.

4月24日に100%ボ-ナスオファーを貰ったので、75000円入金。5月8日に賭け条件満たしたので、勝利金プラス元金622000円を出金申請したところ、規約違反がある旨のメールがあり、勝利金は全額没収、元金75000円のみアカウントに戻される。5月9日75000円出金

メールで規約違反の内容を確認したところ、「ダブルアップを使用している為」とのこと

規約にダブルアップ使用禁止は明記されていないし、長くベッティングしてると意図せずダブルアップのようなベットはでる旨サポートに連絡し、勝利金没収撤回を求めていますが、「担当部署の判断」「一度決定した判断は覆せない」との回答でどうしようもない状況です。

こちらとしては「大勝したから後出しでルールを作り規約違反として出金拒否されている」としか思えません。なんとか助けて貰えるとありがたいです。よろしくお願いします。

返信ありがとうございます。以下質問に回答いたしますので対応の程よろしくお願いします。

・規約違反項目は30.1.7とメール連絡があり、具体的な違反内容を問い合わせしたところ「ダブルアップ」だと

・サポートとのやり取り及びミキカジノ利用規約30.1.7スクショ、を後ほどヴェロニカ様宛メールいたします。

以上よろしくお願いします。　　　さと

Have you sent me any emails yet? I have not received anything. Please double-check if you used the correct email address: veronika.f@casino.guru.

Thank you for your cooperation.

I have resent the email. Thank you in advance.

メール再送しました。よろしくお願いします。

I have checked the Terms and Conditions and this is what I found:

Important notice, in order to protect from high-risk bonus wagering each bet should be less or equal to 20% of original amount of active bonus, if during wagering the bonus a players stakes a bet higher than 20% of original amount of active bonus then such bet will contribute only 20% of original amount of active bonus to wagering requirements.

This means that wagers exceeding 20 % of the bonus should still contribute toward wagering, but only partially. I did not find any provision stating that your winnings may be confiscated solely for breaching this 20 % contribution rule or using double-up features.

To move forward, could you please let me know whether you have already received your complete gaming history from the casino? If so, kindly forward it to me.

I have also not yet received any chat transcripts, emails, or screenshots of your communication with the casino’s customer-support team. These documents are essential for us to understand the casino’s position and advocate effectively on your behalf. Please email them to veronika.f@casino.guru at your earliest convenience.

- I have already checked with support about the 20% rule and received the answer that "there will be no penalty even if you bet more than 20% on this bonus."

・I can check my game history on the website, but I haven't received it again due to this issue.

・The screenshots and correspondence with support have already been sent here, and there are no error messages. I will send you a test email, so please let me know if you received it.

From Veronica If you can send us a blank email, we may be able to resolve your issue.

Thank you for your time.

・20%ルールについては、サポートに既に確認済で、「本ボ-ナスについては20%を超えるべットをしてもペナルティはなし」との回答を貰っています。

・ゲーム履歴はサイト上では確認できますが、今回のトラブルで改めてゲーム履歴を受け取ってはいません

・サポートとのやり取り、スクショはこちらでは送信済になっており、エラーメッセージもありません。テストメールを送信しますので受領できたかお知らせ下さい。

・ヴェロニカ様よりmaeka5010@gmail.comまで空メールいただけると問題解決するかもしれません

以上よろしくお願いします。　　　　　さと

Thank you very much, sato5010, for providing all the necessary information. I will now transfer your complaint to my colleague Michal (michal.k@casino.guru) who will be at your assistance. I wish you the best of luck and hope to see your problem being resolved to your satisfaction in the near future.

Hello sato5010,

I'm Michal, and I have taken over your complaint. I have reviewed this case, and I will contact the casino to see if I can help somehow.

We would like to invite Miki Casino JP to join the conversation.

Dear Miki Casino JP,

Kindly provide us this the rules where it is explicitly mentioned that the "double-up feature" is not allowed. Additionally, even when the player used the "double-up feature", according to your own rules " when players stakes a bet higher than 20% of original amount of active bonus then such bet will contribute only 20% of original amount of active bonus to wagering requirements" the "double-up feature" in theory make no sense as this should not influence the actual bonus wagering requirements.

If I understand it correctly, it appears that the player has not obtained any undue advantage through the use of the 'double-up feature', making it seem unjust to cite this as a basis for seizing the player's winnings.

Should there be any other factors influencing the situation that cannot be shared publicly, please feel free to share them directly with me at michal.k@casino.guru

We would like to ask the casino to reply to this complaint. We are extending the timer by 7 days. If the casino fails to respond in the set time frame, we will close the complaint as ‘unresolved’ which may negatively affect its rating.

Dear sato5010,

I have tried to contact the casino repeatedly but had no success. I’m afraid there is not much that can be achieved without cooperation from their side. I will mark the complaint as "unresolved" in our system. I understand this isn't a satisfactory solution to your issue. However, the decrease in the rating caused by unresolved complaints might help to change the casino's approach. If the casino decides to react, we will reopen the complaint, and you will be notified by email.

Should you want to pursue your complaint further, you can submit it to the Curaçao Gaming Control Board (GCB) via this contact form. Although the GCB does not officially handle disputes between players and gaming operators, they still might be able to help, so it is worth a try.

Please let me know if and how they responded at michal.k@casino.guru if you try this option.

I am sorry I could not be of more help on this occasion.

Best regards,

Michal

Casino Guru

We’ve reopened this complaint at the request of Miki Casino. We would like to allow this case one more chance to be resolved and help both parties involved to reach a satisfactory conclusion.

Dear sato5010,

We have received the following message from the casino team:

Dear CasinoGuru Team,

Thank you for bringing this matter to our attention. 

Upon checking our records, we can see that the customer made a deposit of 75,000 JPY on April 24, 2025, at 14:09:43, and immediately claimed a 100% deposit bonus of 75,000 JPY, resulting in a total bonus amount of 150,000 JPY. This bonus carried a 20x wagering requirement. The customer can review the bonus details and related terms and conditions at any time on our website under the "Claimed Bonuses" section.

On May 8, 2025, at 04:12:25, the customer wagered the bonus, however upon investigation of the user's gameplay, we found that during the bonus play, the customer performed a total of nine double up actions between 15:27:18 and 15:30:05 on April 24, 2025. As stated in our General Terms and Conditions, this constitutes bonus abuse, which may result in all winnings being forfeited in such cases.The relevant excerpt from our General Terms and Conditions states:

"If a player places bets with minimal chance of winning in order to increase wagering volume while the potential return is minimal or zero, this is considered advantage play. In such cases, the bonus, winnings, and any cash used in the process will be immediately forfeited. Clear examples include placing bets on both black and red in roulette, betting on almost all table options, using loss tracking systems such as Martingale, or strategically manipulating bet amounts to complete bonus wagering. Other play styles with similar intent may also be considered abuse. Bets that are clearly intended to have minimal chance of winning while being high in value will be considered a violation of the bonus terms."

The customer's gameplay is considered to fall within the scope of advantageous play and as such is treated as a violation of the Terms and Conditions.

Subsequently, at 07:44:43 on May 9, 2025, the excess winnings of 547,693 JPY were deducted from the customer’s account due to a violation of the Terms and Conditions during the bonus play and the user was informed accordingly.

The customer instructed a withdrawal for 245,459 JPY, which included the refunded deposit and winnings from a separate deposit, which was promptly processed on the same day.

We hope this helps shine some light onto the matter in question. 

Miki Team

Can you please comment on that?

Dear sato5010,

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.

Dear Miki Casino,

I have received this response from the player:

Dear Miharu

I can't reply to the complaint thread so I'm replying here.

I have read the response from Miki Casino. Am I correct in understanding that the nine doublings that were pointed out as a violation of the terms of service were "using the Martingale system"?

I don't think the terms of use that were sent to you previously mentioned a prohibition on the use of the Martingale method.

And

Dear Miharu

What I want to assert is that

They would like to know the details of the "nine doubling-ups" that were deemed to be a violation of the terms and conditions.

From the excerpt of the terms and conditions you sent, it seems highly likely that you will be using a martingale.

① The current regulations have been changed from the April 2025 regulations, and as of April 2025, the "prohibition of the use of martingales" was not clearly stated.

② When I asked for an explanation of the violation of the rules, I was only told that "doubling up" was permitted, and there was no mention of the use of martingale.

Given this, one cannot help but suspect that this explanation is an after-the-fact explanation following a rule change.

Can you please address this?

Dear Miki Casino,

I have received this response from the player:

ミハル様

苦情スレッドに返信できませんのでこちらに返信します。

ミキカジノからの回答を拝見しました。規約違反指摘の９回のダブルアップ行為とは「マーチンゲール法を使用したこと」の理解であってますか？

以前に送付した利用規約にはマーチンゲール法使用禁止は明記されてなかったと思いますが。

And

ミハル様

主張したいのは、

規約違反とされた「９回のダブルアップ行為」の詳細を知りたいということです。

送付された規約抜粋からマーチンゲール使用が可能性が高いと思われますが、

①2025年4月の規約から現在の規約は変更されており、2025年4月時点では「マーチンゲール使用禁止」は明記されていなかった

②規約違反について内容説明を求めた際、「ダブルアップ行為が認められた為」と説明があったのみでマーチンゲール使用については一切言及がなかった

ことから今回の説明は「ルール変更後の事後説明」の可能性を疑わざるを得ません。

Can you please address this?

We would like to ask the casino to reply to this complaint. We are extending the timer by 7 days. If the casino fails to respond in the set time frame, we will close the complaint as ‘unresolved’ which may negatively affect its rating.

Dear sato5010,

Unfortunately, despite the casino team initially expressing a willingness to address the matter and even requesting that we reopen the case, they have since stopped responding to our messages. As much as we would like to help, we cannot resolve a complaint without the cooperation of the casino.

Because the casino has not fully addressed the issue, I'm left with no choice but to close the complaint as unresolved once again. Please know that this is not a conclusion I wish to see, and I genuinely regret that it has come to this.

On a more hopeful note, the impact that unresolved complaints have on a casino's rating can encourage them to reconsider their approach. Should the casino decide to engage with us and address your case appropriately in the future, we will gladly reopen the complaint and notify you immediately by email.

I'm sorry I couldn't be of more help on this occasion.

Best regards,

Michal

Casino Guru
