Casinos to Avoid: Our Blacklist & Red Flags (June 2026)

A good review site tells you where not to play as honestly as where to play. This page lists operators we currently advise UK players to steer clear of, with the documented reason in each case, plus the warning signs that should make you close the tab on any casino. We update it as sites close, change hands or attract serious, evidenced complaints. Inclusion here reflects our editorial assessment of public information and player reports at the time of writing.

Closed or wound-down casinos — do not deposit

The following brands have closed, been wound down or exited the market. They may still appear in old listings or search results, and some shells can linger online — but you should not register or deposit, as recovering a balance from a closing operator ranges from difficult to impossible.

• Regent (Regent Play) — closed; the operating white-label arrangement was wound down. Avoid.
• ZetBet — closed. Avoid.
• Spin Rio — wound down. Avoid.
• mr.play — wound down as part of an operator exit. Avoid.
• Luckster — wound down. Avoid.
• VegasLand — wound down. Avoid.
• Queenplay — wound down. Avoid.

If you hold a balance at any of these, withdraw it immediately and keep records of your transactions.

Operators we rate poorly on trust

• Spinsala — independently rated extremely poorly for safety (a 0.0 “very low” safety index on Casino.guru) with reported withdrawal problems and questions over game fairness. It is not UK-licensed. We would not recommend depositing; if you do, treat it with extreme caution and only money you can afford to lose.

We deliberately keep our reviews balanced, so a casino appearing elsewhere on this site is not an endorsement to ignore its risks — read the full review and our rating methodology for the detail behind each score.

Red flags: how to spot a casino to avoid

Most bad experiences are avoidable if you check for these warning signs before you deposit:

• No verifiable licence. A fake or missing licence, or a “seal” that does not link to the regulator’s live register, is the biggest red flag of all.
• Withdrawal obstruction. Endless “pending” states, surprise documents demanded only at cash-out, or “reverse withdrawal” features designed to tempt you into re-wagering your winnings.
• Predatory bonus terms. Hidden maximum-cashout caps, extreme max-bet rules that void bonuses, or wagering requirements dressed up to look generous.
• No responsible-gambling tools. Missing deposit limits, time-outs or self-exclusion — and any site that advertises being “not on GamStop” as a selling point.
• Confiscation clauses. Vague terms letting the operator void winnings for “irregular play” or accessing from a “restricted country”.
• Anonymous operator. No named company, registered address or contactable support.
• A pattern of unresolved complaints on independent sites like Casino.guru, AskGamblers or Trustpilot — especially about withheld payouts.

Frequently asked questions

Why do you list casinos to avoid?

Because a recommendation only means something if we are also willing to warn you off bad operators. Flagging closed, untrustworthy or predatory sites protects players and keeps our reviews honest, rather than promoting everything for commission.

A casino is on this list but still has a website — is it safe?

No. A site can stay online while winding down or while operating with poor practices. If we have flagged it as closed or low-trust, do not deposit, and withdraw any existing balance promptly.

How do you decide which casinos to blacklist?

We base it on documented public information — confirmed closures, regulator status, independent safety ratings, and recurring, evidenced player complaints about payouts or fairness. We update the list as circumstances change.

What should I do if a casino refuses to pay me?

Gather your evidence (screenshots, transaction IDs, chat logs). If the site is UK-licensed, you can escalate to its Alternative Dispute Resolution provider and the UK Gambling Commission. With an unlicensed offshore site your recourse is limited, which is exactly why licence checks matter before you deposit.
