Jokersino Casino - Player’s winnings are confiscated by closed account.

Illegal confiscation of €1,789 in pending withdrawals after long-standing account validation - JokerSino

I. Nature of the Dispute

I am submitting this formal complaint against JokerSino (operated by Non Videri B.V.) following the illegal voiding of my pending withdrawals totaling €1,789. Following a winning session on March 15th, 2026, the casino closed my account and offered a generic "deposit refund," which I categorically reject as a bad-faith maneuver to avoid paying legitimate winnings.

II. Proof of Prior Validation

The casino’s claim of a "breach of terms" is completely contradicted by my account history. Dozens of my previous withdrawals have been successfully approved and paid out by JokerSino. By processing these past transactions and verifying my KYC documents, the casino officially confirmed that my identity, residency (France), and gameplay were in full compliance with their terms. Invoking a violation only now, specifically to cancel a winning balance, is a clear case of selective and predatory enforcement.

III. Circumstances of the Confiscation

The winnings were generated on high RTP slots (The Catfather / Break Da Bank Again).

Technical Failure: The casino provided no technical blocks or warnings to prevent wagering on these games while a bonus was active.

Retroactive T&C Edits: I have saved the HTML pages of my transaction and bonus history. These records prove that the restrictions used to justify the confiscation were not active or were modified retroactively after my wins were recorded.

Systemic Bad Faith: I have received the exact same automated closure email from four other sister-sites (Slottio, Aphrodite, MadCasino, Kingdom), all operated by Non Videri B.V., proving a coordinated effort to defraud successful players.

IV. Evidence Provided

I am attaching the following documents to this complaint:

Screenshots of the €1,789 in pending withdrawals.

Screenshots of previously "Approved" withdrawal receipts to prove my long-standing compliance.

The automated email confirming the account closure and the incorrect refund offer.

Archived HTML source files of my history on JokerSino.

Conclusion:

JokerSino cannot legally void a contract they have validated several times through prior payments. I request the full payment of my €1,789 and complaints against the Non Videri B.V. group.

Hello,

Thank you for submitting your complaint. I’m sorry to hear about your experience at Jokersino Casino. We believe that restricted games for bonus play should be blocked and that this rule should be implemented at the software level—meaning the casino's software or website should prevent players from placing bets on games that are not permitted during bonus wagering. That would be the ideal solution. Alternatively, at the very least, players should be notified when they access a restricted game that it cannot be played while their bonus is active.

• Could you please advise if you have been warned by the software when accessing any of the restricted games and if it was your first redeemed bonus in this casino?
• Do you have access to your gameplay history in your account? If yes, could you please share it with us?
• If there is any other relevant communication between you and the casino, please forward it to attila.g@casino.guru. Alternatively, you can post it here.

Looking forward to hearing from you.

Best regards,

Attila
