Our independent casino review team has taken a detailed look at OneSlot Casino in this review and evaluated its qualities and drawbacks in accordance with our casino review process. In assessing this casino's safety, our review team has considered crucial factors such as the fairness of its Terms and Conditions, licenses, player complaints, customer support, limits, and other relevant aspects to determine where it falls on the spectrum from safe and legit casino to a potential scam.
Based on the data collected, we have determined the casino's Safety Index, which is a score given to online casinos to describe their level of safety and fairness. The greater the Safety Index, the higher the likelihood of playing and receiving your winnings smoothly. OneSlot Casino has a Very low Safety Index of 3.4, which means it ranks very low in terms of fairness and safety according to our methodology. Carry on reading our OneSlot Casino review to make an informed decision whether or not this casino is the right fit for you.
Fairness and safety of OneSlot Casino
In working out a casino's Safety Index, we utilize a complex formula that acknowledges the collected data that we have addressed in our review. This generally means the casino's T&Cs, complaints from players, estimated revenues, blacklists, and such.
We have carefully examined and analyzed the OneSlot Casino Terms and Conditions as part of our review of OneSlot Casino. To our knowledge, there are no rules or clauses that could be considered unfair or predatory. This is a great sign, as any such rules could potentially be used against players to justify not paying out winnings to them.
Based upon our estimates and collected information, we consider OneSlot Casino one of smaller online casinos . This casino has a very high value of denied payouts in player complaints with respect to its size. Since bigger casinos will often receive more complaints because of the larger number of players, we take into account both the casino's size and player feedback.
As far as we know, no relevant casino blacklists include OneSlot Casino. If a casino has landed itself a spot on a blacklist such as our Casino Guru blacklist, this could mean that the casino has mistreated its customers. When seeking out an online casino to play at, we consider it crucial for player to not take this fact lightly.
All in all, when combined with other factors that come into play in our review, OneSlot Casino has landed a Very low Safety Index of 3.4. We highly encourage players to avoid this casino and seek out one with a higher Safety Index.
OneSlot Casino Terms and Conditions
We go through the Terms and Conditions of each casino we review in great detail and examine their fairness level. In the Terms and Conditions of numerous casinos, we find rules that we regard as unfair or openly exploitative, since these rules are oftentimes the reasons casinos use in order to avoid paying out player winnings.
We did not find any unfair or predatory rules in the Terms and Conditions of OneSlot Casino during our review.
Player complaints about OneSlot Casino
In our casino review methodology, we pay extra attention to player complaints, as they give us an important insight into issues faced by players and the casinos' approach in resolving them. When calculating each casino's Safety Index, we consider all complaints submitted through our Complaint Resolution Center, as well as ones we collect from other sources.
We currently have 8 complaints about this casino in our database. Because of these complaints, we've given this casino 3,408 black points in total. You can find more information about all of the complaints and black points in the 'Safety Index explained' part of this review.
OneSlot Casino user feedback and reviews
Casino Guru provides users with a platform to rate and review online casinos, and to share their feedback or experience. Based on these, we calculate an overall user feedback score, which can range from Terrible to Excellent.
However, there is currently no User feedback score for this casino. We only calculate it after a casino has at least 15 reviews, and we have only received 14 player reviews so far. The reviews have been made available in the User reviews section of this page.
Note: Keep in mind that user reviews may not be the most accurate reflection of the casino's quality. Some reviews may be fake, having been written solely to improve the casino's overall user feedback score. Other reviews may come from dissatisfied players who write numerous negative reviews to worsen the casino's score. While we make every effort to filter out such reviews and determine an unbiased user feedback score, we refrain from incorporating user feedback into our Safety Index calculation due to these factors.

Many online gambling sites place restrictions on the maximum winnings and withdrawal amounts for players. Oftentimes, the win and withdrawal limits are high enough as to not impact most players. That being said, there are casinos, which pose quite restrictive limitations on the win and withdrawal amounts. This is the reason why we consider these limitations in our casino reviews. You can find information about the casino's win and withdrawal limits in the table below.

I had an okay overall experience during my first day with them. I made 3 crypto deposits, claimed their welcome pack bonuses, and had some nice wins. I ended up with a 1.3 K crypto withdrawal. And this is where the fun ends! The only reason why I decided to join and give them a try was the promise on their homepage for "Cashout in minutes!". Well, guess what... Almost 18h later my withdrawal is still not processed yet! Talking about crypto withdrawal that is supposed to be instant INDEED! I can only hope now that it's gonna be processed at all... Very disappointed atm. Strongly encourage any serious depositor to steer clear unless they see reviews confirming that this casino is actually capable to pay their winners as per their own promises!
UPDATE 07/04: Five days later, my withdrawal is still NOT processed despite multiple chats with their support hosts. Of course, they fed me with all the dirty little casino tricks in the book called "How to screw a player" including but not limited to: - "I do not have the ability to approve or speed up withdrawals directly"; (C'mon guys, this is the oldest and cheapest trick, you could do way better!) - "All withdrawal requests especially those under manual review are handled exclusively by our finance and compliance teams, in accordance with strict licensing and security standards" (Yeah, right, just wondering what Anjouan has to do with 'strict licensing and security standards', lol!) - "Your withdrawal request is still in the processing queue and being handled as part of our current high-volume review cycle"; (Now this one beats them all! )
Keep you posted cause I have the odd feeling this nightmare is far from being over :(
Opened account with this new casino and on my first deposit the payment was rejected on the casino end but the funds left my account straight away the casino insisted the funds didn’t go through to them and I had to raise a chargeback request with my bank to recover the funds.
Be very careful with this casino! Does not look good that I need a chargeback on my first deposit, that’s never happened with any other casinos!!!
I think it's definitely a 1-star casino. Customer service is friendly, quick and capable of solving problems. Deposits and the site work flawlessly. Withdrawals....I don't think they can be made any faster than this....worked well.
Mielestäni ehdottomasti 1 korin kasino. Asiakaspalvelu on ystävällisen ripeää ja ratkaisu kykyinen. Talletukset ja sivusto toimii moitteettomasti. Kotiutukset ....en usko että niitä enää tästä voi nopeuttaa....toiminut hyvin.
Surprisingly really good for a new casino! I wasn’t sure what to expect from this casino, but it’s honestly one of the best casinos I’ve played at in a long time. I really like how the games are listed, and the recommendation algorithm actually makes sense, it’s not just random slots thrown at you.
I’ve made two withdrawals so far, and both hit my account in under an hour, which is impressive! Everything has worked as it should, no issues so far.
If anything changes on my experience, I’ll update my review, but so far now, it’s excellence experience.
New casino have always same explain. "No responsibility gambling tools, but we develope it soon" And it never come available. So have to avoid this kind of player unfriendly casino.
My mistake and lost about 10 deposit on few hours. No welcome bonus, no good will bonus. Some poor 5% cashback bonus come tomorrow. Then closure.
Absolutetly love Oneslot! The customer service is always on hand to help you answer any questions you may have. After making a withdrawal, I connect the live support to check the processing time, but the money had already arrived in my bank account. That’s really impressive!
This is solid experience. I havent had any issue with deposits or withdrawals. What i like most is that everything clear. No weird terms or tricky things. Also special compliments for customer support! Thanks for the Alex!
I deposited €50 5 times and only got up to €80 once. It didn't matter which game provider I was using. When I asked if I could get a goodwill bonus, I was told that they don't give out non-deposit bonuses and I can't access the cashback either, as it is only updated every 24 hours. When I asked if the verification was complete, I was told that it was an automatic process that they couldn't influence, even though I had uploaded everything. At the moment I'm inclined to advise against this casino. And the funniest thing is that I only have ten cents left in my account and I can't play any games with it. Every time it says that there isn't enough credit, no matter which game provider I'm using. So it all seems very suspicious to me and I'll wait for the cashback tomorrow and then I'll close my account there. There are much better casinos.
Ich habe 5 × 50 € eingezahlt und bin nur einmal auf 80 € hochgekommen. Egal bei welchem Spiel Anbieter. Auf die Frage, ob ich vielleicht einen Goodwill Bonus bekommen könnte, hiess es, dass sie keine non Deposit Bonus vergeben und auf den Cashback kann ich auch nicht zugreifen, da der nur alle 24 Stunden aktualisiert wird. Auf meine Frage hin, ob die Verifizierung durch ist, sagte man mir, dass es ein automatischer Prozess, auf dem man keinen Einfluss nehmen könnte, obwohl ich alles hochgeladen habe. Im Moment bin ich eher dazu geneigt von diesem Casino ab zu raten. Und das lustigste ist. Ich habe mittlerweile nur noch zehn Cent auf dem Konto und kann aber kein Spiel damit spielen. Jedes Mal steht dann dort, dass da nicht genügend Guthaben drauf ist, egal bei welchem Spiel Anbieter. Also es kommt mir alles sehr suspekt vor und ich werde morgen den Cashback noch abwarten und dann werde ich dort mein Konto schliessen. Da gibt es weitaus viel bessere Casinos
Been playing on this casino for a while, and honestly, it’s one of the best I’ve used last years... Withdrawals are actually really fast. Also support operators are really friendly. This is it! Easy 5 stars.
I don't say this lightly, but I can't remember the last time I've tried a new casino, deposited hundreds of dollars, and had so much losing so fast regardless of bet amounts. No playtime, just straight down over the course of several days. Very few providers available for Canadians. On the upside they have reasonable responsible gaming tools available so I'll be closing my account after their 24 hour mandatory cooling off period.
Nice looking site.
Verification seems straight forward
Easy access to responsible gaming tools
Very few game providers for Canadians
Worst RTP I've experienced in quite some time
No fun was had after spending hundreds on a variety of games

Hey tamalamaland123,
We’re sorry to hear that your session didn’t go as you hoped. While we always want our players to have a great time, luck can sometimes be unpredictable—that’s simply the nature of casino gaming. ☹️
That said, we want to assure you that all our games operate with the highest RTP settings provided by game providers and are fully fair and transparent. We never alter or interfere with game outcomes, as they are controlled by certified RNG (Random Number Generator) technology.
We do appreciate your feedback. If you ever decide to return, we’ll be here with a wide range of games and the same commitment to fairness and player experience. Wishing you all the best! 🎰
They have the fastest bank transfer withdrawal I have ever seen as a casino player for many years. My withdrawal arrived in my bank account within minutes??? I don't think it would have been as fast if I had withdrawn with Bitcoin.
Extremely fast withdrawal
Good layout
Not all providers work with NZD currency
OneSlot Casino
Hey Hey!
That’s what we love to hear! 🔥 Fast withdrawals are a top priority for us, so knowing yours arrived within minutes is awesome. Bank transfers can be surprisingly quick, and we’re always working to keep things smooth
Also we hear you on the NZD providers—while some restrictions exist, we’re always working to expand our offerings.
They have Spanish support is a great start for me, and my withdrawal was sent instantly...
VPN accept

OneSlot Casino
¡España y OneSlot, una combinación ganadora! 🇪🇸✨ Glad to hear our Spanish support made a difference—plus, we’ve got 24/7 support in 20 languages, so you’re always covered!
Enjoy those instant withdrawals, and who knows? Maybe your favorite providers will join the party soon! Good luck, and see you at the tables! 🔥
I found the casino's RTP to be extremely low, almost nonexistent. They claim that you can close your account or take a break from the platform, and promise to send a confirmation email within 24 hours. However, after trying twice, I never received any confirmation, which raises concerns about their credibility. Additionally, the customer support experience is highly disappointing and feels robotic, lacking any genuine assistance.
To be completely honest, I must say im genuinely impressed with this casino. It’s been one of the most outstanding experiences ive seen in a long time. Also my withdrawal was so smooth, and the verification was fast. I truly hope they maintain this level of quality. If I encounter any issues in the future, I’ll update my review, but for now, everything is excellent!
Withdrawal with bank transfer quick
Verification process smooth
Casino design so fresh
They dont have no deposit bonus
Paysafecard doesnt have
OneSlot Casino
Hey!
Thank you for your kind words! It’s always great to hear when players have a smooth and enjoyable experience. Fast withdrawals and an easy verification process are exactly what we aim for, so we’re glad it met your expectations.
We appreciate your feedback on the no deposit bonus and Paysafecard—our team is always looking for ways to improve. Hopefully, we’ll have some exciting updates in the future. 😉 Enjoy your time, and if you ever need anything, we’re here for you!
