One Casino Review

Our independent casino review team has taken a detailed look at One 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. As the Safety Index rises, the probability of encountering problems while playing or making withdrawal lowers. One Casino scored a High Safety Index of 8.9, which is why it could be considered a favorable option for most players in terms of fairness and safety. Continue reading our One Casino review to find out more about this casino and determine if it's the right fit for you.

Fairness and safety of One Casino

In determining a casino's Safety Index, we follow complex methodology that takes into account the variables we have gathered and evaluated in our review. This includes the casino's T&Cs, player complaints, estimated revenues, blacklists, and various other factors.

In our review of One Casino, we thoroughly read and reviewed the Terms and Conditions of One Casino. We found some rules or clauses that were not favorable. Despite our findings, we consider the T&Cs to be mostly fair. An unfair or predatory rule can potentially be used against players to justify not paying out winnings to them, but our findings for this casino were only minor.

Based upon our estimates and collected information, we consider One Casino a very big online casino. This casino has a very low value of denied payouts in player complaints with respect to its size (or it hasn't had any complaints). When evaluating a casino, we consider the number of complaints in relation to the casino's size, since bigger casinos generally receive a higher number of complaints due to a larger player base.

Based on our findings, no important casino blacklists feature One Casino. The presence of a casino on various blacklists, including our own Casino Guru blacklist, is a potential sign of wrongdoing towards customers. Players are encouraged to consider this information when deciding where to play.

Taking into account all factors in our review, One Casino has scored a Safety Index of 8.9, representing a High value. For most players seeking an online casino that prioritizes fairness in the online gambling experience they offer, this casino is a recommendable choice.

Terms and Conditions of One Casino

Whenever we review online casinos, we carefully read each casino's Terms and Conditions and evaluate their fairness. In T&Cs of many of them, we uncover clauses and rules which we consider unfair or outright predatory, as they give the casino the possibility to justify not paying out winnings to players in certain situations.

We found some questionable rules or clauses during our review, however, we consider the Terms and Conditions of One Casino to be mostly fair.

Note: Our particular discoveries from the T&Cs analysis are available here.

Player complaints regarding One Casino

Our casino assessment rests heavily on player complaints, since they provide us valuable data about the issues experienced by players the and the casinos' way of putting things right. When calculating the Safety Index for each casino, we take into account all of the complaints that we get through our Complaint Resolution Center in addition to the complaints that we find elsewhere.

We have found one relevant complaint about this casino. Because of this complaint, we've given this casino 160 black points. You can find more information about the complaint and black points in the 'Safety Index explained' part of this review.

User feedback and reviews of One Casino

At Casino Guru, users have the opportunity to provide ratings and reviews of online casinos in order to share their opinions, feedback, or experiences. Based on these, we then generate a complete user satisfaction score, which varies from Terrible to Excellent.

The user satisfaction feedback of One Casino shared by 46 users has resulted in a Good User feedback score. You may access the casino's user reviews in the User reviews section of this page.

Note: Since it is not uncommon that upset players leave many harmful reviews to damage casino's reputation, and some casinos post false reviews to increase their user feedback score, please note that user reviews may not accurately represent the casino's quality. We strive to filter these out and calculate an accurate user feedback score; however, for these reasons, we do not consider user feedback in our Safety Index calculation.

Licenses and company information

One Casino is owned by One Casino Limited, and we have estimated its yearly revenues to be greater than $100,000,000. This establishes it as a very large online casino within the bounds of our categorization.

One Casino is licensed by Spillemyndigheden in Denmark.

Payment options, withdrawal limits and win limits

One Casino supports 7 deposit methods. This includes: PaySafeCard, Mastercard, VISA, Trustly, PayPal, ApplePay, MobilePay.

There are often restrictions on how much money players can win or withdraw at online casinos. In many cases, these can be high enough not to affect most players, but some casinos do have win or withdrawal limits that can be quite limiting. That is the reason why we look for these while reviewing casinos. The following table provides details on the casino's win and withdrawal limits.

Withdrawal limits Win limits
Unlimited No win limit
Note: It is unlikely that all of the payment options mentioned before can be used for both deposits and withdrawals. Similarly, some payment options may only be used in selected countries.

Language Website Customer support Live chat

Contacting the casino's customer support is part of our review process, so that we know whether players have access to a good quality service. We consider customer support important, as it can be extremely helpful in case you are experiencing issues with registration at One Casino, your account, withdrawals, or anything else.

They are scammers, I registered at this casino, and since I don't have a bank account I used my partner's, to deposit money they don't give you any problems, but when it comes to withdrawing everything they have problems, I deposited €190 from my wife's account and they accepted it without any problems, when it comes to withdrawing they say it's not my account, meaning to pay yes, but to receive no, I sent all the documentation, ID and bank certificate of ownership of my partner, which they asked for, all the documentation was correct, their response was to block and make my casino account disappear along with the money, they didn't return what I deposited €190 or the €300 prize that I won, they are scammers through and through, I understand that there are more similar cases and we will file a collective complaint, it is very shameless that they don't put up obstacles for you to deposit and to collect what is yours no, always from the same bank account...... I have other casino accounts like 888poker, I use the same bank account from my wife and I deposit and withdraw without problem, on the other hand Onecasino are thieves, I understand that if it goes against their policy of using another bank account, then do not accept the deposit, and if you detect the incident as you have done, the least you can do is return the deposit, since it is against the law according to them, but I have everything well documented and put in the hands of justice,

Very few prizes in my experience, I've been playing for 2 years and I'm not convinced, it pays quickly, customer service you write to them in Spanish and they answer you in German, the promotions are very bad and the bonuses are scarce, few providers and I get bored since I'm constantly depositing and I touch nothing, at first it gave something then it was miserable or better yet almost nothing I don't even play the slots. I mean I don't recommend it and now they go and throw my reviews back as always and if it's like that it will be the last time I participate here, because it seems that you can't say what you think. Thanks
  • Quick to pay
  • Very few awards

Don't let my 3-star rating fool you, this place is the real deal, folks!
A generous no-deposit bonus as well as free cash every weekend make One Casino a regular stop for me.

What brings their rating down is the severe lack of providers, however, they just added Pragmatic to their list, so it appears their library will be expanding!

Edit (Feb 19/24): They've been using the sub-96% versions of games for a while now. It's sad when casino management feels the need to increase their house edge.
  • Legit. No shady business here.
  • Growing their gaming library. Focused on improvement.
  • Small game library
  • They're now running the sub-96% versions of most games.

Generally positive. Identity verification is fast and the slots worked correctly on my Android mobile phone. The exceptions were La Mina and Popeye Treasure Hunter, which to play them I had to open the website on my tablet.
The prize percentages are good.

The chat works 24 hours a day and they attended to me correctly.
  • Correct functioning of slots, except those called "bar slots"
  • Quick identity verification.
  • Good percentage of prizes or I was simply lucky.
  • 24 hour chat.
  • The bar slots only worked on my tablet.
  • There are some providers (slots) missing that I personally like a lot.

Cannot put my finger on it about this casino. One thing is guaranteed though. You will never win here. I am not a sore loser. I put so much money in this casino. If you play slots, expect to lose. Thing with this casino is, you cant even get a 200x win. Very odd. Deleted after months of losses. Their bonuses are a joke. High rating casino on here. The worst one I have played. My own opinion.

Top Service... Fast Deposits/Withdrawals!
Constantly new offers and new games
• 2 years ago
Bad casino, hardly any games, chances of winning are very low, I have never been able to request a payout or come close to a payout amount, the bonuses are a bad joke, with paysafe you don't get a bonus, free spins when they come, they are paid with a cent amount afterwards down-eating of the credit hooking and faster-running rollers if a winning picture or scatter is on the way cheeky customer service is of the opinion that one deposits 3x 0.04 cents on a deposit of 50 euros as a profit
  • Unfortunately nothing
  • Everything from support to payout percentage

I recently found this casino, I like it here.
Constantly winning something, there is a pretty good selection of bonuses! The choice of games is also pretty good, about the same as in other casinos.
The only downside is the extremely long verification process. I understand that this is security, but in other casinos it is much faster.
In general - I like it.
  • Constant winnings
  • Good choice of bonuses
  • Standard game selection
  • Long verification process

One Casino is dam good. So far it has been the fastest online casino to look at verification documents. I was verified within two hours of sending the correct information to them. Polite helpful people on live chat. Live chat is easy to find. If you don't reverse your winnings there in your bank account the next day(all casinos are a little slow with first withdrawal) the second withdrawal was made on a Friday and was clear in my account the next day which was a Saturday.
  • Fast verification
  • 20 no deposit chip.
  • Good, helpful people on live chat.
  • They need the option to turn off the reverse option.

I don't know this casino. On 10/28 I suddenly had an email in friends & acquaintances from this casino. It was reported that documents I uploaded were rejected. Aha... I didn't know my password at all, so I requested a new one... then I was in my profile. Apparently I deposited 50 euros here months ago. But I can't imagine that I uploaded documents because this online casino doesn't have a live casino at all, only slots... which, by the way, is always wrong here at Casino Guru. I would be careful and update it if I were you... so much for that...
Well, but apparently I did upload something, for whatever reason... then I saw that my ID card was rejected. At once? Then I realized why. My identity card was only valid until October 28th. valid. And then, after so many months, the identity card is rejected by them? What's that to you? I have never experienced anything like this at an online casino. Apparently they are only out to draw attention to themselves and then make it difficult for you because your ID card has expired... very, very strange!!!

Have been playing there for 2 years, at the beginning, ie 1 year ago it was a top casino with great RTP values. But if you won there 2-3 times a year, it was always only three-digit sums, so you could the next time afterwards Don't play there anymore, regardless of whether it's 10, 20 or 50 euros, you only win small amounts. And that's actually the case. The RTP values are currently in April 2022 in the basement. News from the casino: Unfortunately, they still don't award any Bonus offers, and then only to regular customers, but only if they don't deposit with Paysafe. New games have been added, but not to be compared with King Billy or other big casinos. They also don't send out free spins, and unfortunately they're still closed many stale games there. The rtp is still very low and you have to find it before you start a game
  • There are birthday gifts, Easter and Christmas gifts, the 24/7 chat is great, as a VIP you get a bonus every week. 25 free bingo cards every day. Deposits and withdrawals are very fast there, and verification is incredibly fast there too
  • The selection of slots and providers could be more varied, let's say more modern. Only 1 partner in the household gets this 10 euro welcome bonus, other casinos are more casual, including King Billy, my first casino

The verification of the account is actually a bit long-lasting (it took 2 days because something was always missing) in the end I got my money paid

  • WORSE CUSTOMER SUPPORT
• 2 years ago
Man this is probably the best casino I have found , look at t&c there hardly any you can play what ever slot games , it doesnt say but I dont think there is any max cashout on the no deposits , for a casino the withdrawl time is pretty quick , 10 free cards on bingo jockey every day the games payout for me more often than any other casino I have ever played at. It is a awesome casino It could do with a few more game providers, but they have alot of exclusive slot games. I see some complaining about being stalked , that probably some rogue affiliate. I get one email a week with a free no deposit and usually a deposit bonus whether I have deposited or not that week.
  • straight shooting casino.

  • Page layout well designed
  • Contact was always there
  • After bonuses no winnings
  • Deposits not repeatable
  • Payouts are ongoing
  • Too many emails
  • Just standard slots

I've been harassed by this clan for weeks, yes...that's stalking. My contact details were stolen by criminal connections. Even the permanent cover letter, which this clan finally wants to leave me in peace, is useless. With constantly changing senders, I am harassed and harassed with newsletters, advertising and letters. I myself have nothing to do with casinos, but I can only advise every player that a company that hassles people in such a disgusting way cannot be serious. Anyone who even pays a lot of money to constantly harass people must have a high level of criminal energy, so it is unimaginable that players are dealt with correctly. There are certainly reputable casinos, but onecasino is not one of them, stay away from this gang, be careful!!!!
  • Caution, well advised is he who keeps his hands off this gang.
  • As a non-gamer, I experienced the criminal energy of this clan

I CASHED OUT $500 FROM THE $10 NO DEPOSIT BONUS!

after I verified, linked my bank account, and made a first deposit (which was the minimum deposit of 10$) I had the deposit in my account about 48 hours from the moment I withdrew my winnings. I had placed my withdrawal request at the wrong time (completely my fault). I am sure that it would have deposited in 24 hours or less otherwise.



I was verified ALMOST INSTANTLY. and literally had NO PROBLEMS. I had built up my fortune too about 600$ real money (not bonus money) before I decided to verify, which is where you usually get problems with other casinos, BUT not this ONE.



As soon as I was verified, I linked my bank account, then I made the minimum deposit of 10$ (which is needed to process a withdrawal). I then played a little bit, but decided to cash out at 510$, which was which was actually 500$. Because I didn't play out the 100% welcome bonus I received when I deposited the 10$ it gave me 500$, which is still amazing because some casinos FORCE you to play the out wagering amount before you can cash out the winnings from your no deposit sign up bonus. BIG THUMBS UP for this!!



Usually if I need to make a deposit before withdrawal, I get sceptical. Plus I had to link my account, which I never did with a casino before this ONE. Don't be like me and be sceptical of this casino, it continues to blow my mind how much they base this casino around the player, and they don't feel like a "put your money in and leave" casino.

the game selection is amazing and the customer support was flawless.



I HAD NO PROBLEMSFROM THE BEGINNING AND CONTINUE TO HAVE LITERALLY ZERO PROBLEMS.

THIS IS THE BEST AND MOST PROFESSIONAL ONLINE CASINO. PERIOD.

A SOLID 10 out of 10.

I WILL CONTINUE TO LOYALLY USE THIS CASINO.



If you're feeling lucky, this is the only ONE.



Thank You for the fun and stay awesome , ONE CASINO!!
  • SUPER FAST
  • PROFESSIONAL
  • GREAT LIVE SUPPORT
  • THE BEST ONLINE CASINO

I have been in this small casino for a good 2 years, the registration was very quick, I got the free EUR 10 bonus very quickly, so after 3 hours of play I had together EUR 600, then only had to deposit EUR 20 and the money was already down 1 day on my account.
  • The customer service is also available in German and is very helpful, as a good customer you get a free bonus every week, and a present for your birthday, there are free bingo cards every day, 2x 10.1x 5 cards, a really well-functioning 24/7 chat
  • Only 1 person per household is allowed to have an account, very low RTP value, after a high win it is not possible to play for weeks afterwards, you only win small amounts in the slots. There are no tournaments, special events, etc., actually only slots.
• 3 years ago
So I didn't think that there are still miracles on this planet, of course, unfortunately this casino is limited to this stupid 1 Euro rule and the waiting time between the spins, BUT you have to say you just notice that this casino adheres to the rules

You definitely don't feel ripped off here as a user like in other dubious casinos

90 euros deposit 100% bonus, I managed the wager and paid out 1000 euros and lo and behold, verification on 30 min. Payout on one day.

There is one more thing to note: the bonus wager only starts when you fall into the bonus area

For those who can live with the 1 euro stake and that you have to bring some time with you, this casino is absolutely perfect and can only be recommended
  • clear homepage
  • great customer support
  • quick payout
  • fair casino
  • up to now few provider providers
