Frequently Asked Questions About Mr Sloty Casino
Is Mr Sloty Casino Safe and Legitimate?
No, Mr Sloty is NOT considered safe by expert reviewers. The casino has a “Very low Safety Index of 1.2, demonstrating a significant deficiency in terms of fairness and safety” according to Casino Guru’s methodology. The casino operates under a Curacao license, which provides minimal player protection compared to UK or Malta licenses.
Major Red Flags:
- Very high amount of restrained payouts in complaints from players when taking its size into account
- Unfair Terms and Conditions that “can potentially be used against players to justify not paying out winnings”
- No verification from UK Gambling Commission or other reputable regulators
Will I Actually Receive My Withdrawals?
This is the biggest concern with Mr Sloty. Player reviews consistently report withdrawal delays, with complaints like “Absolutely joke of a casino, three times i have withdrew and twice went back into my account, waiting over 6 months for my winnings, stay clear of these scammers”
Common Withdrawal Problems:
- Players waiting 3+ months for withdrawals
- Withdrawals cancelled and returned to player accounts multiple times
- Customer support providing “same automated message” and unhelpful responses
- Casino’s “history of not responding to complaints” according to mediation services
How Does the 400% Welcome Bonus Work?
The casino advertises a 400% bonus up to £2,000 on your first deposit, but this comes with severe restrictions:
Bonus Terms:
- Minimum deposit: £20
- Wagering requirement: 50x the bonus amount
- Bonus is “sticky” (deducted upon first withdrawal)
- Limited to slots games only
- Must be used within 30 days
Warning: The high bonus is described as potentially being used “to lure you in and get your money” with players reporting difficulty actually withdrawing even after meeting requirements
What Games Can I Play?
Mr Sloty offers approximately 700 games including:
Game Categories:
- Slots: Video slots, classic slots, progressive jackpots
- Table Games: Blackjack, roulette, baccarat variants
- Live Casino: Live dealer games (limited selection)
- Sports Betting: 30+ sports with 200+ football markets
Software Providers:

Does Mr Sloty Have Customer Support?
Technically yes, but it’s widely criticized:
- Live chat: Available but provides scripted responses
- Email: support@mrslotymail.com (often bounces back or no response)
- Phone: +44-3308087970 (reported as fake/non-working number)
Players report that support is “unhelpful and rude” and will “disconnect you when you question them about what happening with withdrawal”
Is Mr Sloty on GamStop?
No, Mr Sloty is not on GamStop. This means “punters on self-exclusion at UKGC sites can still register and play games at this casino with no restriction”. While this might seem like a benefit, it also means you have no UK regulatory protection.

Final Safety Message:
The combination of an unlicensed casino with a terrible reputation for paying withdrawals makes Mr Sloty particularly dangerous for anyone with gambling problems. The large bonuses and “not on GamStop” marketing specifically target vulnerable players. Please choose licensed, reputable alternatives and remember that responsible gambling is the only safe gambling.
Conclusion
Mr Sloty Casino presents an attractive front with generous bonuses and a large game selection, but the reality is far different. With overwhelming evidence of withdrawal problems, poor customer service, and a very low safety rating from experts, this casino poses significant risks to players’ funds.
The simple advice: Stay away from Mr Sloty Casino. There are numerous licensed, reputable alternatives that will actually pay your winnings and provide proper customer support. Don’t be tempted by large bonuses that you may never be able to withdraw.
If you’re looking for online gambling entertainment, choose operators licensed by the UK Gambling Commission, Malta Gaming Authority, or other reputable regulators who put player protection first.
Remember: If it seems too good to be true, it probably is. Your money and peace of mind are worth more than any bonus offer.
