Casino Dispute Evidence

Casino Changed the Rules After You Won?
Prove It Before They Edit the Page.

If an online casino refuses to pay your winnings in 2026, capture the bonus terms, the withdrawal screen and the support chat before the operator edits them. ProofSnap, a Chrome extension, seals each page into a timestamped forensic package that Casino Guru, eCOGRA and card issuers accept as evidence, carrying a SHA-256 hash and an RSA-4096 signature.

Casino Guru's Complaint Resolution Center has returned more than $60 million to players since 2019 (Casino Guru, March 2026), and the AskGamblers Casino Complaint Service recovered $10.7 million across 3,779 resolved cases in 2025 (AskGamblers, May 2026). Casino Guru and AskGamblers both require documented evidence. One click, 41 seconds, an evidence package of 11 to 15 files depending on your plan.

Casino dispute? Quick answers.

Will a screenshot hold up?
Rarely. eCOGRA requires "rock-solid, undisputed, unambiguous evidence." AskGamblers rejects complaints with "insufficient information."
What evidence do I need?
Timestamped captures of the bonus terms, account balance, withdrawal status, chat transcripts and KYC requests.
What's the chargeback deadline?
120 days from the transaction date (Visa Core Rules and Mastercard Chargeback Guide, 2026). After that, your right to dispute expires.
Where do I file a complaint?
Casino Guru, eCOGRA, AskGamblers, UKGC (UK), MGA (Malta), or the casino's licensing authority.

3 steps. 41 seconds. Court-ready evidence.

ProofSnap captures forensic casino evidence that Casino Guru, eCOGRA, and licensing authorities actually accept.

Casino won't pay? You're not alone.

Every day, online casinos use these tactics against players. Without forensic evidence, your complaint gets rejected.

Bonus Terms Changed After You Won

You accepted a bonus with 30x wagering. You met the terms. The casino then raised it to 50x, or added game restrictions that did not exist when you opted in, and voided your winnings.

Evidence needed: T&C page captured BEFORE you started playing

Withdrawal Refused or Delayed

You won. You requested a withdrawal. It's been "pending" for weeks. The casino cites "irregular play patterns," "bonus abuse," or endless verification. They're waiting for you to cancel and gamble it back.

Evidence needed: account balance, withdrawal request, pending status, all timestamped

KYC Stall Tactics

Deposits were instant. But now that you want to withdraw, the casino needs "additional verification". Every document you send is "insufficient". Months pass. The casino is hoping you give up.

Evidence needed: every KYC request, upload, and response, all timestamped

Account Closed, Balance Seized

The casino closed your account, citing vague "terms violations", and confiscated your balance. No explanation. No appeal. Account access revoked along with all your evidence.

Evidence needed: balance screenshot, closure notification, all communications BEFORE lockout

Max Cashout Cap on Jackpot Win

You hit a jackpot worth €50,000 on slots. Buried in the bonus terms: max cashout €5,000. You lose 90% of your winnings to a clause you never saw when you accepted the bonus.

Evidence needed: bonus terms page at time of opt-in showing no cashout limit

Self-Exclusion Violation

You requested self-exclusion. The casino kept sending marketing emails, or let you re-register. Under UKGC and MGA rules the operator is liable, but only if you can prove it happened.

Evidence needed: self-exclusion request, marketing emails, login access, all timestamped

Casino Guru has returned more than $60 million to players since 2019 (Casino Guru, March 2026). Only documented complaints got paid.

The AskGamblers Casino Complaint Service recovered $10,728,000 across 3,779 resolved cases in 2025, which is 68% of all accepted cases (AskGamblers, May 2026). Without evidence, a complaint is rejected before it is investigated.

Real players. Real casinos. Real money lost.

Jacqueline Davis turned a $50 deposit into $3,289,500.75 on BetMGM roulette in March 2021. BetMGM paid $100,000, then blamed a software malfunction and kept the rest. On 22 July 2025 the Michigan Supreme Court ruled unanimously that she can sue, sending the case back to the Wayne County Circuit Court. She has still not been paid.

DraftKings "Deal or No Deal Banker's Bonanza" returned no wins between 15 and 21 August 2023. 522 Connecticut players, more than 20,659 spins, no wins on a game advertised with a return to player of roughly 95%. Connecticut's Department of Consumer Protection fined DraftKings and White Hat Gaming $22,500 in total, and DraftKings refunded $23,909.

$112,188

Digital Gaming Corporation, the Super Group operator behind Jackpot City and Spin Casino, failed to add self-excluded players to New Jersey's exclusion list between March 2024 and January 2025. In October 2025 the New Jersey Division of Gaming Enforcement fined it $112,188.96 and ordered the return of $5,278 in winnings. The operator has since closed its US online gaming business.

The casino has a compliance team.
What do you have?

When you file a complaint, the casino responds with server logs, IP records, game history data, and a legal team. You send one screenshot that anyone could have faked in Photoshop. eCOGRA and AskGamblers, the two bodies that handle most of these cases, say plainly what they need.

Your Screenshot

  • No timestamp proof: when was it taken?
  • Easily edited in 30 seconds (Photoshop, Inspect Element)
  • No metadata, no URL verification
  • No chain of custody
  • Just one image file
  • Rejected by Casino Guru, eCOGRA, and regulators

ProofSnap Evidence Package

  • Blockchain timestamp: immutable proof of when
  • SHA-256 hash: any tampering detected instantly
  • Full metadata: URL, IP, headers, TLS certificate, cookies
  • Forensic log + chain of custody documentation
  • 11 to 15 files: screenshot, HTML, DOM text, PDF, metadata, forensic log
  • Accepted by Casino Guru, eCOGRA, licensing authorities

Every ProofSnap capture ships with a Provenance Certificate that records eight independent integrity checks, and on the Enterprise plan the package carries an eIDAS qualified timestamp issued by Disig a.s., a Qualified Trust Service Provider on the EU Trusted List. Anyone, including the casino, can re-verify the package years later with the free ProofSnap Trust Verifier, without a ProofSnap account.

"Complainants should provide rock-solid, undisputed, unambiguous evidence to support their claims."

eCOGRA ADR Requirements

"If you fail to provide requested information or evidence, your complaint will be rejected."

AskGamblers Casino Complaint Service

Already in a dispute? It's not too late.

Most visitors land here after a casino has already refused to pay. There is still time. Critical evidence is still on the site right now, before the casino changes those pages.

Capture these 7 things in the next 10 minutes:

Why this matters even if you already have screenshots: Your casino will argue your screenshots are edited. With ProofSnap, each capture carries a SHA-256 hash, a digital signature and a blockchain timestamp that independently prove what you captured and when. That is the difference between "insufficient evidence" and a successful Casino Guru complaint.

A €5,000 jackpot. A $200 bonus dispute. A £50 withdrawal stuck for 2 months. The amount does not matter. The evidence process is the same, and the 7-day trial covers it.

Curaçao / offshore casino (Stake, BC.Game, 1xBet Casino, Roobet)

  1. 1. File with the operator. If no response, submit to Casino Guru or AskGamblers.

888 Casino or Betway dispute?

888 Casino and Betway both have long public complaint histories on Casino Guru and AskGamblers. The recurring themes are withdrawal delays, bonus terms changed after the fact, and accounts closed while a balance was still in them. Capture your account pages, the bonus terms, and the chat transcripts before you are locked out.

LeoVegas or PokerStars Casino dispute?

LeoVegas and PokerStars Casino hold MGA and UKGC licences. The recurring issues are max cashout caps on bonus winnings, game contribution disputes and KYC stalling. File with the MGA Player Support Function, which requires documented, timestamped evidence.

Stake, BC.Game, or 1xBet Casino?

Stake, BC.Game and 1xBet Casino are licensed in Curaçao, where regulatory enforcement is minimal. Timestamped forensic proof is often the difference between recovering your money and losing it.
