Clean and Uncluttered – OnlyWin Offers No Fuss Casino Gaming
OnlyWin launched in 2023 as a pure online casino – no esports or sports betting here – just slots, instant win, table and live dealer games. Notably, it’s one of the crypto casinos that’s stuck with a Curaçao license into the new regime, which also means KYC is now required for everyone, rendering it off limits for players in many major markets.
In this original CoinBets OnlyWin casino review, I’ll be signing up and wagering real crypto to get an authentic player experience. As always, I’ll be paying close attention to the welcome bonus, payment options, games portfolio, and casino features.
So, can OnlyWin compete in today’s hyper competitive crypto gambling market? Keep reading to find out.

Welcome Bonus
Bonus size, terms, and fairness
At the time of writing this OnlyWin casino review, new players could qualify for a welcome bonus worth up to EUR €2,000 plus 210 free spins. Sounds okay, but let’s see how it breaks down:
Welcome package is split over first four deposits as follows:
1st deposit bonus: 100% bonus up to €400 + 100 FS (Gates of Olympus, Sugar Rush, Coin Volcano, 777 Coins)
2nd deposit bonus: 120% bonus up to €400 + 60 FS (Gold Express, 777 Coins, Coin UP: Hot Fire)
3rd deposit bonus: 50% bonus up to €800 + 50 FS (Gold Express)
4th deposit bonus: 100% bonus up to €400
Important terms:
Available to for up to 31 days from registration
Min deposit €20
Free spins must be activated in “Bonus” section of account
Wagering requirement: 40x (bonus + winnings from free spins)
Max wager with bonus funds is €5
Max win: €2,000
Deposit bonus valid for 5 days
The Only.Win casino welcome package looks reasonable. Most importantly, all of the terms are readily provided (once you’ve opened an account and logged in, at least), and clearly written. The wagering is about average, but importantly, is based on the bonus amount, not the bonus + deposit. 5 days to complete wagering is a bit tight, but still not unusual, and the max win of €2K is reasonable considering the minimum deposit.
All in all, not amazing, but certainly nowhere near the worst casino welcome bonus I’ve seen recently.
Opening a New Account
Sign-up speed and steps
Opening a new player account at Only.Win is quick and easy, but the only option is email.
Tap “Sign Up”. Enter your email and set a strong password. Click “Sign Up”.
Enter your first and last names, and confirm your date of birth and sex.
Tap “Last Step”. Enter your city, postal code, and mobile phone number, then click “Complete.”
Important: From 2025 onwards, stricter Curaçao regulations require licensees to conduct KYC checks to verify the age and identity of all players. So, while you can still use a VPN to sign-up, deposit, and play at casinos like OnlyWin, you won’t be able to withdraw if you are playing from a prohibited jurisdiction. Such countries and regions are listed in the Terms and Conditions (section 4.6), and include the United States and United Kingdom.
Payments
According to information displayed on the Only.win casino homepage, it supports the following cryptocurrencies for deposits and withdrawals:
However, at the time of writing, only BTC, USDT, and USDC seemed to be available at the cashier.
To make a crypto deposit, navigate to “Cashier”, then select “Deposit.” Choose the appropriate cryptocurrency, and you will be provided with a unique deposit address in both QR code and text formats. You’ll also have the option to active any available bonuses.
To withdraw crypto, go to “Cashier” and select “Withdraw.” Choose the crypto and network (if applicable), enter the address of the wallet you want to withdraw to and state the amount you want to transfer. The estimated transaction fee will be displayed. If it all looks good, confirm the request.
Important note: As per the OnlyWin user agreement, all deposited funds must be wagered 3x before they can be withdrawn. This is significantly higher than the 1x usually required to comply with anti-money laundering rules (AML).
CoinBets.com Tip: Always double-check crypto wallet addresses after pasting them – you don’t want to fall victim to ‘PasteJacking’. This is when hackers exploit the copy-paste function to change wallet addresses to steal funds.
Only.Win also supports fiat options including Visa, Mastercard, and MiFinity.
Buying Crypto
Unlike the best crypto casinos, Only.Win does not allow you to purchase crypto directly via providers like MoonPay or Changelly.
Game Selection
At the time of writing this OnlyWin review, the platform offered around 2,200 casino games of all types, from over 80 providers. Overall, the games lobby is clean and easy to navigate, without too much bloating. Things seem to be well organized here, with useful filters like Bonus Buy, Jackpots, Megaways, etc.

Slots
Game variety
Of course, the bulk of games at Only.Win casino are slots – just under 2,000 of them in total. While reviewing, the most popular slots included Mustang Trail and Spell Master from Pragmatic Play, Magic Clovers from 3Oaks, and Coin Strike: Hold and Win from Playson.
As mentioned, the handy filters make it easy to find specific types of slots. For example, if you’re a Megways fan, you’ll find nearly 130 options, including Mustang Gold Megaways from Pragmatic, Wild Coyote Megaways from OneTouch, and Atlantis Megaways from Yggdrasil. Meanwhile, the jackpot slots category has almost 700 titles, ranging from Coin Blaze by Platipus and 3 Tombs from Amigo, to Fishy Business from TrueLab and Lucky Streak 1000 from Endorphina.
CoinBets Experience
Mustang Trail (Pragmatic Play)
Just for a change, I decided to get things rolling here at OnlyWin with a western. Yes, I know, shocking – you’ve probably never seen this theme before, right? Well, yep, Mustang Trail from Pragmatic Play is absolutely as clichéd as it looks. But, it’s so tacky, it’s kind of fun. So, I played 50 x $1 bets on this beast.
But before I tell you how my latest Wild West adventure went, here’s a bit about the slot. It was released in mid 2024, has a very average 96.04% RTP, and a moderate maximum win of 5,000x your bet. Features are pretty limited – random wilds spawn from wilds, and the bonus round with sticky wilds is useful. But, really, Mustang Trail doesn’t have much going for it.
And as for my luck? I was all out of it. After burning 50 bucks on it, I’d only won back 14.50 – for a disappointing real RTP of just 29%.
Moving swiftly on…
Majestic Jaguar (Spinomenal)
For some reason, I stuck with the wild animal theme, but this time headed further south, into Central America and the dense jungles the Majestic Jaguar calls home. Eh, hang on a minute… is that a gorilla? It appears the team over at Spinomenal are geographically challenged (or maybe they’ve been relying on AI for research?).
Oh well, I played 50 x $1 spins anyway.
Right, so this game was only released in July 2025, but I must admit I never noticed it. The theoretical RTP is 96.31% and it’s got a medium volatility rating – something that’s actually becoming quite rare, in a space flooded with highly volatile slots. As for features? Well, it’s quite impressive – there’s a free spins bonus game, hold and win, multipliers, random wild and additional wilds, respins, scatters, and stacks.
Buuuut, just like the previous slot, I really couldn’t get into this. Gameplay wise it just felt dull. And while my luck did improve a little, I still only managed to win back $25.92 – making for a crappy 51.84% real RTP.
I should keep away from the animal games today.
Crash & Instant Wins
Fast gameplay
Thankfully, Only.Win also provides a crash games category (if you’re a regular at CoinBets, you’ll know I hate it when casinos lump crash games in with slots). In it, you’ll find almost 60 titles, ranging from Penalty Duel and SpaceXY from BGaming, to Pilot from Gamzix, CricketX from SmartSoft, and of course, the omnipresent Aviator from Spribe.
In terms of other instant win games, there are also dedicated Scratch Games and Pinko categories – the former containing over 50 games, and the latter, almost 30.
Live Casino
Dealer quality
Boasting a tad over 200 games (if you include the handful of miscategorized non-live tables), the OnlyWin live casino is about average in terms of size.
The choice of live blackjack, roulette, baccarat, and poker, is dominated by Pragmatic Play Live, with additional games from Live88, Amusement, VivoGaming, BetGames.TV, Iconic21 and tvbet. The one notable absence is Evolution – something that will no doubt put many players off.
Indeed, the lack of Evolution here means the choice of live game shows is very limited, with just 7 options – all from Pragmatic Play. However, they do include big hits like Sweet Bonanza Candyland, Mega Wheel, and Treasure Island.
Table Games and Video Poker
Classic tables
There’s also a convenient category for RNG-based table games. Yep, just video blackjack, roulette, baccarat, dice, and poker games, without any live dealer games getting in the way. Seriously, this sounds like a simple thing, but so many crypto casinos seem incapable of properly sorting games these days – so well done to the Only.win team.
In total, there are just shy of 100 table games to choose from. Specific titles available include Blackjack Supreme Multihand from OneTouch, Video Poker 3 in 1 from Mascot Gaming, French Roulette from Evoplay, and Baccarat from GameArt.
Bingo
Casual games
There’s no specific bingo category at Only.Win casino, but a quick search turned up almost 60 video bingo games – which is very respectable. Caleta Gaming dominates the lineup here, with video bingo games like Atlantis Bingo, Banana Bingo, and Betina Bingo. There are also options from Belatra, G Games, Platipus, Wazdan, NetGame, Mascot, and SlotMatrix. 24 keno games are also offered, again mostly from Caleta Gaming.

CoinBets Challenge: Candy Do or Candy Can’t?
Our real-money gameplay results
After being fleeced by the slots so far at Only.win casino, and with a bonus limiting my game choices, what was I to do for today’s CoinBets Challenge? Ah, yep, you’ve guessed it, I turned to my emergency slot – Sweet Bonanza from Pragmatic Play. This slot usually seems to come through and turn things around.
And, it’s got absolutely no animals in it.
So, I decided to play 50 x $1 standard spins, and then challenge myself to beat the resulting RTP with 50 x $1.25 boosted spins. Now, theoretically, the latter doubles your chances of winning a feature – but would it help me recover?
In a word, no.
I just couldn’t catch a break at OnlyWin. Even on my trusty Sweet Bonanza. The standard spins returned $38.20 – an RTP of 76.40%.
While the boosted spins did trigger a bonus game, I still only managed to win back $43.70% – an RTP of just 69.92%.
Challenge failed.

Quality and Speed
OnlyWin crypto casino offers 24/7 live support – though this is provided by a bot, so it’s not the greatest. Real agents are available on request, but you may have to wait a while. You can also send a message via a form, or email support [at] only [dot] win.
The most common questions are also answered in a small but neat FAQ section, and you can connect with OnlyWin via X (Twitter), Facebook, Instagram, and rather unusually, LinkedIn.
User Experience & Website Design
Navigation, layout, and performance
OnlyWin looks and feels like countless other contemporary online casinos – but it’s fast, easy to navigate, and everything seems to work. Importantly, once you’re logged in, most information can be found pretty easily, and things are clearly written. Depositing and withdrawing are straightforward too, with a clean interface.
As previously mentioned, the extensive categories make browsing games easy here, but the lack of in-house titles is noticeable. In the same vein, the lack of any real crypto-first features like a native token, NFTs, or DeFi features is going to put many crypto gamblers off. Indeed, this is basically an old school Web2 online casino that happens to accept some crypto payments.
When it comes to responsible gambling, OnlyWin does reference limits that can be set from within player profiles, but I couldn’t find them. I suspect they are going to be introduced shortly to comply with the updated Curacao gambling regulations. So, for now, if you want to self-exclude or set limits, you’ll need to contact support.
In addition to English, Only.Win casino is available in the following languages:
Languages
Mobile apps
Gameplay and usability on mobile
As already mentioned, dedicated OnlyWin casino apps are available for Android, iOS, and Windows devices. Apparently, they offers “secret extra bonuses” and “even more faster withdrawals.” So, yeah, even more faster… I despair. Anyway, you can download the OnlyWin app from the website – just scroll to the footer for links.
Overall Reputation
So, we’ve seen what OnlyWin has to offer in terms of gambling products, but what are players saying about it? Well, as always, you should take the following ratings with a pinch of salt – most are from highly biased iGaming affiliates, and even Trustpilot is being destroyed by massive reputation laundering campaigns. Heck, that’s why we set up CoinBets – to bring you the truth.
| Platform | Overall Rating | Notes |
|---|---|---|
 | 3.4 Average | (based on 72 reviews) |
 | 9.3/10 Safety Index: Very High | User feedback: Excellent (44 reviews) |
 | CasinoRank: 8.5 Very Good | Player Rating: 9.1 (54 reviews) |

Okay, so what’s my overall impression of OnlyWin casino? Well, I think the phrase that comes to mind is “so-so.” There’s nothing really terrible going on here, but there’s also nothing particularly great.
Verdict
Okay, so what’s my overall impression of OnlyWin casino? Well, I think the phrase that comes to mind is “so-so.” There’s nothing really terrible going on here, but there’s also nothing particularly great.
On the one hand, the casino itself seems to work and is reasonably well organized. The categories are useful and navigation is smooth – things aren’t bloated and glitchy like at so many crypto casinos. But the game catalog is also much smaller than at many competitors, there’s a distinct lack of crypto support and features, and of course, there’s no sports or esports betting available.
The bonuses and loyalty/VIP program seem very average, but could be rewarding if you’re a high roller. And, of course, you need to keep in mind that, thanks to the new Curacao rules, you’ll need to verify your identity before you can withdraw anything – even a small amount (so, there’s no point even trying the VPN trick if you’re in a prohibited jurisdiction). Another major issue is the 3x wagering for all funds – which seems unreasonable. Sure, all casinos require deposits to be wagered 1x to combat money laundering – but 3x? That doesn’t seem fair.
So, if you can deal with the wagering and you’re just looking for a simple, no-frills online casino that supports some major cryptos, OnlyWin could be worth trying. As always, if you do give Only.Win casino a try, I recommend keeping your balance low until you’ve got your account fully verified and feel comfortable
But, that’s just what I think. How about you? Have you played at OnlyWin casino? If so, why not write your own CoinBets review and share your thoughts with the play community?
Thanks for reading, and until next time, good luck, stay safe, and may your luck be better than mine.
