One Casino Review

Our expert casino review team has carefully analysed One Casino in this review and evaluated its positives and negatives using our casino review process. They considered the fairness of the casino's Terms and Conditions, licenses, complaints from existing players, customer support, limits, and other important factors to figure out whether this casino is safe and legit, an outright scam, or somewhere in between.

Based on these markers, we have calculated the Safety Index, a score that summarizes our analysis of the safety and fairness of online casinos. A higher Safety Index decreases the probability of experiencing issues when playing or making a withdrawal. One Casino scored a High Safety Index of 8.9, which makes it a recommendable option for most players in terms of fairness and player safety. Read our One Casino review to discover more about this casino and decide whether it is a suitable option for you.

Safety Index of One Casino – Is it fair and safe?

We calculate a casino's Safety Index based on an elaborate formula that takes into consideration a wide range of information that we have collected and assessed in our review. These involve the casino's estimated revenues, complaints from the players, T&Cs, blacklists, and so on.

In our review of One Casino, we meticulously evaluated and analyzed the Terms and Conditions of One Casino. We came across some rules or clauses that we did not appreciate, but all in all, we consider the T&Cs to be mostly fair. A rule that is unfair or predatory has the potential to be held against players to defend withholding their winnings, but in the case of this casino, we found only minor issues.

One Casino is a very big online casino based on our estimates or collected information. Considering its size, this casino has a very low sum of disputed winnings in complaints from players (or it has not received any complaints whatsoever). We consider both the casino's size and the number of player complaints and how they correlate, seeing as bigger casinos tend to receive more complaints due to the larger number of players.

As far as we know, no relevant casino blacklists include One Casino. If a casino is included on a blacklist such as our Casino Guru blacklist, this could hint that the casino has committed some kind of misconduct towards its customers. We urge players to keep this in mind when searching for an online casino to play at.

In our comprehensive review of all relevant aspects, One Casino has attained a High Safety Index of 8.9. This makes it a recommendable option for most players who are looking for an online casino that creates a fair environment for their customers.

One Casino Terms and Conditions

When evaluating online casinos, we meticulously analyze each casino's Terms and Conditions with the aim to assess their fairness level. In T&Cs of many casinos, we come across certain clauses, which we perceive as unjust or overtly predatory. In some cases, these give the casino the possibility to justify withholding player winnings.

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: Please take a look at our particular findings from the T&Cs examination here.

Player complaints about One Casino

Player complaints play an important part in our casino review methodology, as they give us a clear insight into issues experienced by players and casinos’ way of handling them. We take into account all complaints filed via our Complaint Resolution Center in addition to those we compile from other sources when examining each casino's safety and fairness.

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.

One Casino user feedback and reviews

On Casino Guru, users can rate and review online casinos to voice their opinions, feedback, or experience. Based on these, we generate a total user feedback that varies between Terrible and Excellent.

Judging by the 45 user reviews given to One Casino, it has a Good User feedback score. You can find the reviews in the User reviews part of this page.

Note: It's important to note that user reviews may not always provide an objective reflection of the casino's quality. Instances exist where casinos write fake reviews to boost their user feedback score, while some dissatisfied players leave multiple negative reviews to tarnish the casino's reputation. Our best efforts are put into filtering these out and calculating an objectively accurate user feedback score; nonetheless, we do not include user feedback in our Safety Index calculation.

One Casino company data and licenses

One Casino is owned by FPO Spain, PLC and has estimated annual revenues higher than $100,000,000. Based on the categorization we use, this makes it a very big online casino.

One Casino has a gambling license issued by Dirección General de Ordenación del Juego in Spain.

Win and withdrawal limits, payment options

One Casino accepts deposits via 6 payment methods. This includes: PaySafeCard, VISA, Mastercard, Sofort Banking, PayPal, ApplePay.

Online casinos frequently impose limitations on the amounts players can win or withdraw. While these are generally high enough not to impact the majority of players, several casinos do impose quite restrictive win or withdrawal limits. That is why we always check these when reviewing casinos. The table below shows the casino's win and withdrawal limitations.

Withdrawal limits Win limits
Unlimited No win limit
Note: It is likely that not all of the payment methods listed above are suitable for both deposits and withdrawals. Furthermore, certain payment options may only be available in specific countries.

Available language options and customer support

When reviewing online casinos, we collect information about their customer support and language options. In the table below, you can see an overview of language options at One Casino.

Language Website Customer support Live chat
English Yes Yes Yes24/7
Spanish Yes Yes Yes24/7

Our team contacted the customer support during the review process to gain an accurate picture of the quality of the service. We find customer support important, since its purpose is to help you resolve any issues you might experience, such as registration at One Casino, account management, withdrawal process, etc. Based on the test we have conducted, we have rated the customer support of One Casino as fast and professional.

My experience with One Casino is good so far. It shines with awesome bonuses and lightning-fast withdrawals, making it a solid pick for a smooth online gaming experience.

  • excellent costumer support

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.
• 11 months ago
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
• 1 year 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
• 1 year ago
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
• 2 years ago
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

worst customer support!!! not friendly!!!!!!! dumb...
  • WORSE CUSTOMER SUPPORT

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.
• 2 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
