OneSlot Sister Sites 2025
OneSlot isn’t the only casino on the Just Gaming Solutions Limitada platform. It is, however, the only casino on the network that’s likely to be of any interest to you. Our audience is largely based in the English-speaking world, with most of our readers living in the UK. The current OneSlot sister sites don’t serve that market. For the sake of completion, though, there are two other Just Gaming Solutions Limitada brands: DedeSlot, which is a Turkish-language casino, and NasaBet 260, which is locked down so tightly that we can’t even get to it with a proxy browser. Only OneSlot is available worldwide, and in making itself available worldwide, it breaks a lot of laws, not least those in the UK.
Given that the operator has now apparently started targetting a wider audience, it remains entirely possible that new OneSlot sister sites will be added in the future. We’ll keep an eye on the situation, and if anything changes, this page will be updated. For now, here’s the most comprehensive review of OneSlot Casino you’ll find anywhere on the net.

OneSlot Review 2025
The motto of OneSlot is “meet the casino again” – a phrase that’s intended to suggest that Just Gaming Solutions Limitata has found a way to completely re-invent the online casino experience. Needless to say, they haven’t. For all its claims about saying goodbye to the “frustrations” of traditional casinos in favour of “real entertainment,” OneSlot is easy to identify as an online casino that looks much like a thousand others. All casinos are guilty of hyperbole, though, and we might be able to forgive OneSlot for the unfounded boast if it’s able to offer us a world-class casino experience. Can it do so? Let’s see.
OneSlot Welcome Offers
New players at OneSlot can claim up to £2250 through the welcome package, starting with a 100% match up to £1000 on deposit one. That’s followed by 75% up to £750 on deposit two and 50% up to £500 on deposit three, thus bringing up the full promised amount. It’s an above-average bonus, and the x40 wagering requirements attached to it aren’t so far above the industry average that we’ll complain about them. All in all, it’s a solid offer to new arrivals on the casino’s homepage.
Ongoing Promotions
Several of the ongoing promotions at OneSlot are linked to the casino’s VIP loyalty reward scheme, which we’ll be discussing as a separate topic in a moment. Not all of them are, though. As an example, the monthly bonus is a once-per-month 100% match up to £250, with the same x40 wagering requirements in place. There’s also an equivalent weekly offer of 50% up to £125, again subject to the same wagering requirements.
Some of the other offers listed on the OneSlot Promotions page include instant rakeback, birthday surprises, cashback of up to thirty per cent every day, and the chance to win a Tesla Cybertruck (which you’d presumably sell immediately before it exploded). However, given that the rates and specifics of these perks are wrapped up in the OneSlot VIP Club, it’s time we moved on to that.
OneSlot Casino VIP Club
The OneSlot Casino VIP Club promises an extravagant rewards system for its most dedicated players, though its structure reveals both perks and pitfalls. Entry begins at the Bronze tier with £100K in wagers, progressing to Platinum for those staking an eye-watering £25M. Benefits include daily cashback ranging from 10% at Bronze to 30% at Platinum—among the highest in the industry—along with rakeback bonuses and exclusive perks like luxury getaways and tickets to prestigious events. From the Gold tier onwards, a dedicated VIP manager is assigned to personalise your rewards, ensuring you feel pampered as you climb the ranks.
However, the exclusivity comes at a steep price. The wagering requirements for tier progression are extraordinarily high, making the programme accessible only to the wealthiest players. While the programme markets itself as “limitless,” its emphasis on elite tiers risks alienating mid-level spenders. Overall, it’s a flashy scheme but only feasible for a very select few.
What are the Pros and Cons of OneSlot Casino?
Pros: OneSlot’s welcome promotion offers new players a decent start to life with the brand, and the weekly and monthly bonuses are worth having, too. If you’re in the top 1% of earners on planet Earth, you might also be able to get some value out of the OneSlot VIP Club. Overall, the platform of games is strong.
Cons: The casino simply promises more than it can deliver. It promises something new, but there’s nothing genuinely new here. The wagering requirements to get to the bottom rung of the VIP Club are high, and those required to make it to the very top are astronomical. 99% of players will never get anywhere near them. OneSlot specifically and aggressively targets the UK despite not having a licence to operate here, and that’s very illegal.
Top Games at OneSlot
We’ll give OneSlot some credit here; it’s tried to do something genuinely different with the slots and games that it features on its homepage. Instead of picking obvious, popular titles, it leads with “Hidden Gems,” including The Final Countdown by Big Time Gaming, and Queen of Riches from the same provider. Curse of the Pharaoh: Bonus Buy by EvoPlay also makes the cut, as does Good Girl, Bad Girl by Betsoft. All your favourite slots are probably here to be found somewhere if you look hard enough, but OneSlot would rather show you things you might never have seen before.
You wouldn’t necessarily expect a casino with a name like this to offer anything other than slots, but OneSlot also has a range of live casino games available. However, they’re not exactly top-of-the-shop quality. Evolution Gaming has recently decided to get out of the black market casino game, so it’s pulled supply from casinos that target the UK illegally. As such, OneSlot has been left with suppliers like Atmosphera and Iconic21, who supply basic baccarat, roulette and blackjack titles, but very little beyond that. If you keep digging, you might eventually find a few basic game show titles from Tom Horn Gaming – a supplier that’s well-known for slots but is very new to the live dealer scene.
Withdrawal Processing and Support
There’s very little information available anywhere on the OneSlot website about this. The casino claims that most withdrawals are processed somewhere between zero and seventy-two hours, with a possible delay of up to seven business days if manual checks are required. However, the casino never tells us which methods it does or doesn’t support. The text of the terms and conditions strongly implies that cryptocurrency support is provided, but there’s no confirmation of this or any other method. All in all, it’s not good enough.
Customer Support and Licensing
Players can contact OneSlot Casino either by using the live chat service or by emailing [email protected]. The casino is covered by the Internet Gaming Licence that its operator, Just Gaming Solutions Limitada, holds in the State of Anjouan. Despite having “United Kingdom” in its logo and carrying a link to GamStop, OneSlot has no licence nor any legal permission to carry out business in the UK, and it’s breaking the law by doing so. UK players shouldn’t register or play here – they have no regulatory protection if they do.
OneSlot – The Verdict
Specifically targeting UK players without a UK Gambling Commission licence is one of the biggest offences that an online casino can commit, and OneSlot has committed it. For that reason alone, we don’t recommend playing here – it’s operating outside the law, and casinos that do so can never be trusted. If it’s legal to play at OneSlot where you live, we think it’s probably so-so. Its mouth writes a cheque that it can’t cash in terms of being new and original with its content, but it’s still a solid casino with decent bonuses so long as it can be trusted to do what it says it will do. Given the licensing issue, there are no guarantees on that front.
