OneSlot is one of the newest online casinos to launch, and it is also one of the first launches for 2025. That makes the house pretty exciting, as it feels like it is a glimpse into the future of iGaming in this year. And the website of the casino certainly does match that feeling, with a pretty minimalist and stylish theme, making it both easy to browse and pleasant to look at.
But aside from its aesthetics, there is quite a lot to enjoy within the actual services of the gambling house, too! For instance, the casino features a pretty significant range of Games, with over 9000 titles being available within it in total. That's why we would like to take a closer look into what OneSlot has to offer, and examine the gambling house's services in the thorough review of it we've prepared here. We will first take a look at the bonuses of the casino, then, into its regulation and finally, we'll examine the casino's payment methods and games. So, without further ado, let's jump right into it:
OneSlot Bonuses and Promo Codes
The promotions of this online gambling house are pretty good by all accounts, but lack in originality. Before we give you an overview of them, though, you should know that there are certain Restricted countries for the promotions of OneSlot. The casino claims that players from these countries will not be able to get any bonus it offers, but does not specify what these countries are. We would have liked to see a list of them!
Still, let's turn our attention into the bonuses that OneSlot features. Here is a look into what those are:
Bonus | Min deposit | Max bonus | Wagering requirements | Cash out limit |
Welcome Package | $20 | 100% up to $2250 | 40x | $10000 |
Monthly Bonus | $20 | 100% up to $500 | 40x | $10000 |
Weekly Bonus | $20 | 50% up to $125 | 40x | $10000 |
VIP Perks | - | Unspecified | - | - |
And before we touch on any of these promotions, we'd like to discuss the No deposit bonuses of OneSlot. There might not be any such promotions within the gambling house at the time of writing, but it is possible for the casino to introduce one soon! Its Bonus Terms and Conditions contain quite a lot of mentions of what the promotions would look like and how they would work. That way, we know that the house will let you withdraw your No deposit bonuses up to a maximum of $50, which is a compelling limit. So, we hope to see a No deposit promotion offered by OneSlot sooner rather than later! Still, in the meantime, here's what the rest of the promotions of the casino are:
The Welcome bonuses of OneSlot:
OneSlot features a package of three fairly sizeable Welcome bonuses, which its players can claim over the course of that many initial deposits. In total, this package of bonuses adds up to $2250 to your account, which is a pretty sizeable maximum. Here is a breakdown of what each of the three bonuses of OneSlot provides you with:
- First Deposit bonus: 100% of your initial deposit, up to $1000.
- Second Deposit bonus: 75% of your deposited funds added to your account, up to $750.
- Third Deposit Bonus: 50% deposit bonus up to $500 to round out the Welcome package.
These are decently sized promotions, though the latter ones are decidedly less generous than the First Deposit bonus. Claiming any one of them requires a minimum deposit limit of $20, which is in line with what the majority of online casinos these days tend to ask for, too.
The funds from the bonus can be used to play any game of the casino, and you can even withdraw up to a total of $10 000 from it, which is a fair enough maximum cash-out limit. Of course, in order to do so, you do need to clear the wagering requriement of the promotion, which has been set to 40x the deposited funds.
Wagering requirements are a natural part of the promotions of any online casino nowadays, and represent a certain amount of times you need to wager the bonus in order to cash it out. The average wagering requirement we would expect to see from other casinos for similar promotions is generally set to 30x-40x the bonus amount, too, which means OneSlot's Welcome package is competitive.
Overall, we do like the bonus, even if it could really stand to offer players a bit more than just a bunch of extra Cash. There could also have been Free Spins, or a temporary Cashback and so on. Still, there's something to be said about sticking to what works, and handing out massive cash promotions to new players certainly does!
The Monthly Reload bonus of OneSlot
Next, there is a Monthly Reload bonus with the casino, which can be claimed once per month, though you can receive it an unlimited amount of months. The promotion simply adds 100% of your deposited funds up to $250 to your account, which is extra cash you can play with on any Game you might want to.
The promotion does have a fair enough maximum limit, but it could very well be higher, too, considering you can get it once every 30 or so days. There are online casinos which offer similarly sized bonuses every week.
Claiming the bonus also requires you to deposit $20 or more. There is also a maximum withdrawal limit to it, too, which is also set to the same amount of $10 000. Considering this promotion is nine times less than the Welcome bonus package, which also had the same limit, that is great.
The wagering requriement of this bonus is once again set to 40x the bonus amount. We do like that, because it is in line with the majority of other promotions we tend to cover, as we explained.
The Weekly Reload bonus of OneSlot
Another Reload bonus which can be claimed an indefinite amount of times is available to the players of this casino. Crucially, you can receive this promotion only once per week, as its name suggests.
The bonus consists of a 50% boost for your deposited funds, up to a maximum of $125. It seems like OneSlot has just taken the monthly bonus and divided its percentage and maximum limit in half to get this promotion! As we said, there are plenty of gambling houses out there, which tend to have higher bonuses available on a weekly basis. Still, you can get up to a total of $500 per month from these Weekly Reload offers, which is not too bad.
You will not be surprised to discover that the casino's minimum deposit limit for this bonus is set to $20, as was the case with the rest of the promotions it offered. Also, the maximum withdrawal limit from it is still $10 000, which, given the smaller size of the promotion, is a pretty great feature overall!
The wagering requirement for the promotion is still set to 40x, in line with the standard average we tend to see such limits within the majority of online casinos for their similar promotions. So, all in all, the Weekly Reload offer of OneSlot is not too bad.
And, as a whole, the Welcome and Reload bonuses of OneSlot do have their charm, even if they are not all that original. We would have still liked to see a couple of Free Spin offers, though, or a more robust range of Reload offers to pick from!
The VIP perks of OneSlot
Finally, as a lot of online gambling houses these days, OneSlot has a VIP program. The goal of this program is to reward the most loyal players of the gambling house with exclusive account perks, while also giving newly signed up ones something to look forward to.
The VIP program is fairly straightforward, too, which is great. The house ranks player accounts into five VIP levels. Those are called Bronze, Silver, Gold, Diamond and Platinum. Every account starts a level below Bronze, called Standard, which means the casino does not offer an instant VIP system.
Still, you can climb the ranks of the system by betting more and more, and unlock plenty of compelling perks along the way. Do be aware that reaching even the Bronze level of the VIP program requires you to wager a total of $100 000 within the casino, meaning it takes quite a lot of commitment and resources to advance in the ranks.
The perks for leveling up your account are the following:
- Level-up bonuses: Every account tier you climb will award you with a special Level up bonus. The one for reaching the Bronze tier is a $100 cash prize, though there is no way to know what the other levels' tiers are.
- Birthday bonuses: VIP player from all account tiers have access to exclusive birthday bonuses. These are kept secret by the casino, and we cannot really say exactly how generous they are.
- Rakeback Rewards: A Rakeback is a special bonus which gives you a small percentage of the house edge on every bet you place, regardless of its outcome. The house edge represents the percentage of your funds the casino expects to receive from the bets you place. That way, most Slots have a house edge around 3% at most. The Rakeback is counted as 5% of that, and can be claimed without needing to be wagered by players.
- Cashback Reward: There is also a Cashback bonus that all players can make use of. This promotion lets you get a certain percentage of your losses credited back to your account. You can cash out these funds without needing to wage anything, and the bonus can be received on a daily, weekly, or even monthly basis, whenever you want to withdraw it. Keep in mind you can only withdraw it if you have not placed any withdrawal request within the day, and that you cannot stack it with any other bonus. As for what the promotion entails, it nets you 5%-30% of your losses, up to $500 to $15 000, depending on your account level. Even Standard account players can make use of the bonus, at its lowest percentage and maximum outlined above, which is great.
Overall, the VIP perks of this casino are fairly rewarding indeed! We think they represent a pretty good incentive for its players to stick around with OneSlot and keep playing there, and that they do somewhat make up for the rather unimaginative Reload bonuses of the house!
OneSlot License
Next, one of the only ways to know you are dealing with a legitimate online casino is to ensure that the house you are gambling in is licensed. And we are happy to report that OneSlot is actually a licensed online gambling house! Its operator, called Just Gaming Solutions Limitada, a company registered in Costa Rica, has obtained a license with the Anjouan Gaming Authority.
This Authority has been tasked with overseeing the iGaming market of the autonomous island of Anjouan, within the Comoros Union. And said market has been booming as of late, with more and more gambling houses applying for Anjouan regulation! Back to OneSlot, though, here is the license of the gambling house we pulled from the register of Anjouan's license issuer:
So, what does that mean for the players of the gambling house? Well, Anjouan Gaming is able to guarantee the legitimacy of the house, meaning it is safe to cash in there. Another policy of the regulatory body that we really like has to do with the integrity of the games that are allowed to be offered to player.
You see, before a casino licensed by Anjouan Gaming offers you any Slot, Table Game and so on, it must have submitted the title for RNG testing. RNG means “Random number generator” and refers to the complex mathematical algorithms that gambling software makers use to determine the outcomes of player bets. So, when you are placing your bets within OneSlot, you can be certain that this generator, and, consequently, the outcomes of the bets themselves, are going to be unbiased.
That said, there are more protections that players can depend on from Anjouan-licensed online gambling houses. These houses are required to prevent minors from opening accounts and even help the regulatory body combat money-laundering and other financial crime that could otherwise take place in casinos, which makes the online gambling world safer for everyone.
As much as we like the Anjouan Gaming regulatory regime, we would be amiss not to mention that there are also a couple of other gambling regulators out there, which can offer players an even stricter set of regulatory protections. Among them are the MGA and UKGC, which ask the gambling houses they oversee to monitor player behavior in real time and help you out if they detect gambling addiction patterns in it, for instance.
Still, even if it does not have the strictest license out there, we are reasonably happy with what OneSlot has to offer! Before we close this chapter of our review, though, we should go over a couple more aspects of the casino, such as the different languages that the house allows you to view its website in:
Languages: English, Spanish, German, Dutch, Portuguese, Hindi, Chinese, Arabic, French, Russian, Japanese, Polish, Korean, Turkish, Vietnamese, Greek, Norwegian, Finnish
We love how diverse this list is, because it means that OneSlot is committed to offering players from all over the world a gambling experience in their native tongue, which is usually a sign of a very high-quality casino! That said, OneSlot does not accept players from every country on the planet. In keeping up with regulatory requirements, the casino does not open accounts to players from the following:
Restricted countries: Afghanistan, Angola, Anguilla, Barbados, Burkina Faso, Cayman Islands, Central African Republic, Comoros, Congo (Brazzaville), Congo (Kinshasa), Côte d'Ivoire, Eritrea, France, French Guiana, French Polynesia, French Southern Lands, Haiti, Iran, Jersey, Korea, North, Show All, Liberia, Libya, Mali, Mauritius, Myanmar, Nicaragua, Rwanda, Saint Martin (French part), Sierra Leone, Somalia, Yemen, Zimbabwe
OneSlot Deposit and Withdrawal
There is quite a lot to go over with the deposit and withdrawal conditions of the house. In general, though, we consider them to be pretty good! Here is a list of the payment methods that you can use to cash in to OneSlot, as well as the currencies the house accepts:
The deposit conditions of OneSlot:
Deposit method | Minimum | Maximum | Processing time | Fee |
Credit/Debit Card | $20 | $2000 | Instant | Free |
Bank | $20 | $2500 | Instant | Free |
Revolut | $20 | $2500 | Instant | Free |
Crypto | $20 | Unspecified | Instant | Free |
Currencies: US Dollar (USD), Australian Dollar (AUD), Brazilian Real (BRL), Canadian Dollar (CAD), Swiss Franc (CHF), Euro (EUR), British Pound Sterling (GBP), Indian Rupee (INR), New Zealand Dollar (NZD), Norwegian Krone (NOK), Polish zloty (PLN), Singapore Dollar (SGD), Swedish Krona (SEK), Turkish Lira (TRY), Bitcoin (BTC), Tether (USDT), Litecoin (LTC), Ethereum (ETH), Cardano (ADA), Dogecoin (DOGE), USD Coin (USDC), Binance Coin (BNB)
First things first, the range of payment methods is not particularly diverse, but OneSlot still lets you cash in via a decent range of FIAT and crypto payment methods. This includes credit cards, bank transfers and Revolut payments, as well as the cryptocurrencies we've listed above.
However, what really stood out to us about the deposit policies of OneSlot is the sheer range of the currencies it accepts! The casino features a plethora of different FIAT currencies from all over the world, which can all be used to open accounts. This means that you can avoid having to deal with annoying conversion fees! It once again shows the commitment of OneSlot to players from all over the world, and making it easier for anyone to cash in!
The minimum deposit to the house has been set to no more than $20 across all of its payment methods. In general, that is in line with the majority of online casinos these days, even if some houses tend to have a lower minimum entry cost requriement, up to $10. Still, what OneSlot demands from its players is not particularly bad either.
Finally, there are no fees for cashing in to the casino, at least none by OneSlot itself. That is pretty excellent, as no gambling house that is worth its salt nowadays would burden its players with such unnecessary charges! That said, third party charges, such as banking or crypto miner fees are still going to be possible with the casino, so be aware of those, too.
Now, let's take a look at the withdrawal conditions of OneSlot, too:
The withdrawal policies of OneSlot
Most online casinos these days implement a deposit wagering policy within their Terms and Conditions. That is the case here, too, with OneSlot asking its players to have a total wagering volume of at least 3x their total deposited amount before withdrawing. Failing to meet this requriement is going to result in your cash-out request being denied.
That policy is designed to comply with anti-money laundering regulation, and the average amount of times you generally need to play through the funds you wish to cash out from casinos is generally set to 1x-3x your deposited amount. So, even on the high end of that range, the casino does have a reasonable withdrawal policy, in our view. With that in mind, here are the actual withdrawal conditions it has in store for players:
Withdrawal method | Minimum | Maximum | Processing time | Fee |
Bank | $20 | $300000 | up to 3 days | Free |
Crypto | $20 | $300000 | up to 3 days | Free |
First things first, the range of payment methods is drastically lower than what you could use to cash in. In fact, it is exactly twice as low as that! Still, if you are trying to withdraw via FIAT, you can use a bank transfer, and direct crypto withdrawals are available, too.
The minimum you are allowed to cash out is set to $20, which is fair enough. Even though other casinos can sometimes allow you to withdraw as little as $10 or under, we would not really say this makes the minimum of OneSlot uncompetitive. After all, that is how much you could deposit at lowest as well, so it's fair in our book!
However, we don't like that the maximum withdrawal limit from the gambling house is determined as loosely as it is. Supposedly, it has been set to $150 000-300 000 per month, which is an absolutely massive amount, but how much you can cash out per transaction is not specified in the Terms and Conditions of the house at all!
The processing times for withdrawals from the gambling house are set to up to 3 days. Note that the average processing times for OneSlot are likely to be lower than that maximum on average! However, there could be delays if you are withdrawing via international bank transfer. These delays could be as long as a couple of days, with some banks taking up to a week to process such transactions. Still, that is outside of the control of the casino! Crypto payments, in contrast, are usually processed within up to a coupe of hours at most.
No fees are charged to the players of OneSlot for processing their withdrawal requests, which is great. Still, as per what we said above, there could be third party charges which you will have to cover. That is the case with almost any online casino you can play in nowadays, though.
OneSlot Games and Game Suppliers
The range of Games and Suppliers of OneSlot is the last feature of the casino we'd like to cover, but it is very important! A gambling house could have excellent bonuses, regulation and so on, and still fail because there are not enough games for its players to enjoy. We are happy to say that this is not going to be the case here at all! Instead, there is a plethora of different titles for players to enjoy, by 98 Suppliers in total. For reference, we generally expect to see around 50 or so Suppliers within the houses we cover, which means that OneSlot has twice as many as this usual average.
We'd like to start our coverage of the library of OneSlot exactly with a look into the following list of Suppliers which the casino has partnered with:
Game providers: 5 Men, Amatic, Slotmill, Evoplay, Gamzix, Leander, Mancala, NetEnt, NetGame, Nucleus, OneTouch, 1x2gaming, Onlyplay, Wizard, Playson, RubyPlay, Smartsoft Gaming, Spearhead, Spinomenal, Swintt, Thunderkick, Tom Horn, Yggdrasil, ReelPlay, Gamebeat, Bulletproof, 4ThePlayer, Gamevy, Big Time Gaming, Bang Bang Games, Fantasma, Reflex Gaming, CT Interactive, Petersons, Wazdan, AvatarUX, LuckyStreak, Platipus, PragmaticPlay, Nolimit City, Gaming Corps, BGaming, Novomatic, 1spin4win, Fazi, Betsoft, Blueprint, Booming Games, 3 Oaks, Felix Gaming, Fugaso, GameArt, Habanero, Igrosoft, IGTech, KA Gaming, Kalamba, Mascot, PGSoft, Quickspin, Red Tiger Gaming, TrueLab, Turbogames, Zillion, 7Mojos, Merkur, EAgaming, Reevo, Amigo Gaming, Evolution, Ezugi, Atmosfera, Alg, Other
First things first, there are a number of different popular Suppliers here, including PragmaticPlay, NetEnt, Evolution gaming and so on. This means that some of the most popular Games you could play nowadays are going to be available within the casino! And since there are twice as many Suppliers as we expected, the total amount of these Games was also significantly higher than anticipated. In total, we think that OneSlot has more than 9000 Games to offer, by our best estimates!
That said, if you are interested in taking a look at the different types of games within the casino, you can do so below:
- Slots: There are thousands of Slots to pick from within the casino, contrary to its name! Among them are popular titles, such as Big Bass Bonanza, Book of Dead, Wolf's Gold and more, as well as thousands of lesser-known games to explore. Of course, all manner of Slot types are available, too, such as Jackpot Slots, Bonus Buy Slots and so on.
- Table Games: If you are looking for a more traditional casino experience rather than playing Slots, you should consider the massive range of Table Games with OneSlot! There are plenty of different virtual and live dealer rooms to tune in to an enjoy games like Baccarat, Poker, Blackjack, Roulettes and so on, in various rulesets and languages!
- Game Shows: Since OneSlot partners with casino software makers such as Evolution Gaming and PragmaticPlay, it also features a pretty decent collection of Game Shows that players could tune into. Among them are the likes of Crazy Time, Gonzo's Treasure Hunt, Crazy Coin Flip and so on.
- Crash Games: Even though there is no Crash Games section on the website of OneSlot, there are plenty of these titles to enjoy within the casino! Among them are the likes of Christmas Crash, Piggy Crash and Mighty Crash. Nevertheless, for the ease of access of players, we would have liked to see them in a different tab of the library of the online casino.
Conclusion
There is a ton to like within this casino, and we believe we could recommend checking it out. The only notable downside it has in our view is the fact that the bonuses it offers might be fairly plentiful, but are pretty uncreative and might get boring fast. If you think so too, don't hesitate to check out the rest of our reviews to find a better place to play. Otherwise, you could have hours upon hours of fun with this safe online casino and its absolutely staggering range of Games, while also benefitting from a reliable set of deposit and withdrawal policies!
