Hello,
We are very sorry and concerned to hear about this charge.
We want to assure you that we would never take funds from your account without authorisation. This sounds like it may be a temporary pre-authorisation check made by a payment provider to validate your card, which is usually reversed quickly.
However, we need to confirm this for you urgently. Please contact our Customer Service team immediately with your account details so we can investigate and get this resolved for you.
All the best, SlotBoss

Hi there Hannah,
Thank you for your feedback.
We understand your profound frustration and anger at winning money, verifying your identity, only to be paid significantly less and have your account immediately shut down.
This is absolutely unacceptable. We are immediately launching an urgent investigation into the discrepancy in your winnings and the sudden account closure to rectify this grave issue.
Please be aware that we have a 24/7 Live chat service that you can contact for more information.

Hi Vedat,
We can certainly understand your frustration after experiencing a losing streak of that length on Blackjack.
We want to provide assurance that all our games are governed by certified Random Number Generators (RNGs), as required by our UK Gambling Commission licence. This ensures every hand is completely independent of the last.
While a long losing streak is exceptionally unlucky and disheartening, the nature of randomness means such sequences are statistically possible.
If you would like us to review the game history for that session, please contact our 24/7 Live Chat. We can provide a full breakdown of the hands for your peace of mind.
Kind regards, Slot Boss

Dear Kerry,
We have noted the comments regarding the account being closed for a Safer Gambling review following a win. We recognise how disappointing and stressful it is to have an account locked after being verified, especially when you have funds pending. As a licensed operator, we are required to conduct such reviews, and our team works to complete them as quickly as possible, after which they will communicate the outcome.
Please be aware that I have sent you an internal request through Trustpilot for me to be able to contact you directly and to be in a position to handle your concerns.

SlotBoss.
Hmmm
Not sure how familiar everyone is with the huff n puff series as is relatively new to uk online casino.
But yesterday I deposited £100. I played 50p spins for 2 hours so nothing fancy and my money didn’t go down that quickly. BUT during this time (my ODC causes me to count everything) I got 5 hat bonuses, 3 buzz saw features and three yes THREE extremely rare golden buzz saw features. And at no point during this time was I more than £10 up. I gave it three stars because some online casinos just swallow up £100 in dead spins in 20 minutes.
But I’ve been playing huff n puff a lot these last few months. And I’d it’s easily the worst returns I’ve ever had, on a playing spell during which I’ve had more of the best bonuses you can get.
You can preach random number generator bla bla bla. That’s nonsense as the number generator has to be set at a level that coincides with the RTP. To have that many bonuses, especially three golden buzz saw bonuses and never be more than £10 is easily the most ridiculous casino experience I can remember having.
Post reply edit:
Here’s the stats from the last 3 bonuses I’ve won.
First bonus win - £39
\/
£45.5 wagered in 50p spins
\/
Next bonus win - £14.56
\/
239 spins after bonus
103 x 50p = £51.5
134 x 40p = £53.6
2 x 70p = £1.40
Wagered £106.5
Line pay wins- £31.25
\/
Most recent bonus win £14.40
(Had a mini bonus in the middle of the next 109 spins that won £10)
Wagered - £55
Wins (not including £10mini ) = £11.99
Total spins - 437
Total stake - £207
Total wins from line pays - £55.37
Total wins from THREE BONUSES - £40.96
Total wins overall - £94.33
Loss - £112.67
This would be understandable if was just spinning and spinning. But there was three bonus rounds included in this which is what we play for, as the returns are greater. And this is only my last 3 bonus rounds remember and the spins inbetween. I don’t have the time or energy to go back and look through since I started playing. But it ALL looks like this. And on top of this twice I went 20+ spins IN A ROW without so much as winning 10p from a line pay. Over £8 of 40p consecutive spons without a return. And I stopped counting the amount of 10+ spins without a return as the numbers were starting to make my vision blurry.

Scam company
I am extremely dissatisfied with my recent experience with SlotBoss. After making a deposit into my account, I was subsequently restricted from accessing the platform so I advised that I wish to close my account which has been done
What is most concerning is that SlotBoss has refused to provide any timescale for when my deposited funds will be returned. This lack of transparency and accountability is unacceptable, particularly when dealing with customers’ money.
Consumers are entitled to clarity, fair treatment, and prompt access to their own funds. Unfortunately, my experience with SlotBoss has fallen far short of these standards. At present, I remain unable to access my deposit and have no assurance as to when this matter will be resolved.
I would strongly advise others to exercise caution before depositing money with SlotBoss until they demonstrate greater transparency and reliability in how they handle customer accounts and funds.

Hi there Dawn,
Thank you for bringing this extremely serious and concerning matter to my attention regarding your recent experience with funds being withheld after your account was restricted and subsequently closed. I
can absolutely understand your extreme dissatisfaction and distress; it is completely unacceptable to be denied access to your own deposited funds without a clear timeline for their return, and this lack of transparency is deeply concerning.
I want to assure you that I am launching an immediate and thorough investigation into this situation to understand why your funds have not been returned, what led to the account restriction, and to ensure a prompt resolution for you.

Absolute rip off went to try it out never again!
Absolute rip off went to try it out tonight applied for there welcome "bonus" what a rip off so at it goes your meant to recieve so many free spins and a deposit bonus..well to get any of these you have to wager your deposit 35x so you need to play around £350 on games now on games like starburst and Kong these wagering requirements are realistic and easily met on most gambling sites
Not on slotboss the games are totally and utterly rigged 15 spins on Kong 3 not one win or cash collect of any sort at all
4 starbursts nearly consecutively not a win on any of them.
These games dont behave like that anywhere else.
Slotboss must be aware of this because are point blank refusing to refund my deposit somthing tells me theres money going to upper management somewhere thats ill gained
Look at alot of the reviews and they all point jn the same direction of the casino reeling it in and paying out very little
And if you try to put an honest review on other sites for slotboss they refuse to put tjem up
proberley in Slot boss's pockets hence why.

Banned for 5 years!!!
Been playing slots for years and lost regularly!
For the first time in years I actually won a decent amount - couple of grand (pennies to these betting sites)
Today I had a phone call and had 100 questions and now banned from their platform for 5years - for my own safety!!
I just wish these companies would reach out to people and ban them when they are losing! People get themselves into all sorts of problems and even take their own lives!

Total SCAM gambling site... BE WARNED !!!!!
I've put over 2k into this 'casino' and walked away without a penny. I wouldn't mind so much if I had enjoyed the experience... just feels 'CHEAP AND NASTY' and that you're getting ripped off at one of those fun fair stalls. Closed my account and can only warn other people not to bother... up to you but my opinion is that it is total shite!

Dear Customer,
We are sorry to hear that your return to Slot Boss did not meet your expectations.
We would like to remind you of the importance of RTP (Return to Player), a percentage that indicates how much bets are returned to players over a long period of time. While RTP does not guarantee short-term profits, it ensures a fair gaming experience in the long run.
Please note that I have sent an internal request via Trustpilot so that I can contact you directly and address your query further.

I signed up about a year ago and they never asked me for ID .I’ve deposited and withdrawn and the minute I win big big they lock my account I have sent my ID got all the green ticks and I’ve still cannot get back into my account they want to see bank statements of my income. They are in the wrong because they should not be asking now .because of a big win when they should’ have asked in the beginning. I have looked into this and I’ve gone a bit higher and if they don’t cooperate with me, I will be taking it further.

One of the worst experiences I've had, constantly breach the terms of their licensing agreement by only requesting documents when trying withdraw but will allow you to deposit and gamble without any verification.They request more documents than any other site I have used.
