Sloterra Casino launched in 2022, offering Kiwis an online casino with support for fast crypto payments and withdrawals. Licensed and regulated in the online gambling hub of Curacao, Sloterra presents a cool selection of over 4,000 games from some of the best names in the business. Alongside the usual array of pokies and table games, I was impressed by the selection of live dealer games and crypto games, which set this apart from the crowd.
In this Sloterra casino review, I’ll give my own experiences with Sloterra – the good and the bad – to help you form your judgement about whether you should play here.

Sloterra bonuses tend to be on the generous side, both in terms of the amounts on offer and the terms attached. I was surprised to see the online casino bonus I was offered on the way in - an attractive proposition for any casino fan searching for a new place to play.
The bonus terms and conditions were generally fair when I read through, but I’d always recommend reading for yourself. These can change at any time, and it’s always worth knowing where you stand.
When I first landed at Sloterra, I was intrigued by the casino welcome package. For me, this came in at a 375% deposit match across my first four deposits, up to NZ$1,400. I didn’t max it out personally, but with a reasonable 35x wagering requirement on the other side, I felt this was a pretty good start.
The casino bonus can be used to bet on a range of different games, though I’d recommend watching out for the contribution. Only pokies contribute 100% towards the wagering, so it’s best to use your bonus on pokies to meet the wagering requirement more easily.
I found that withdrawal at Sloterra was contingent on completing KYC - even for withdrawals to crypto. While the bonus wagering wasn’t too bad at 35x, I wish I’d completed my KYC process sooner. This would’ve made the whole withdrawal process much quicker.
Luckily, withdrawals to cryptocurrency are virtually instant once processing has been complete, so I didn’t have to wait too long to receive my winnings. I’d say Sloterra is about average on the withdrawal difficulty side, though you can speed up the process no end by completing your KYC verification early doors.
Note that there’s also a 3x minimum wagering requirement on every deposit. This is in place as an anti-money laundering measure, to protect Sloterra and its players from criminal activity.
Games come by the sack load at Sloterra, with a fine selection of pokies, table games and live dealer games from leading developers. I was a little surprised to see only 20 developers contributing games here. For a collection that runs to over 4,000 titles, that’s surprisingly few developers.
Nevertheless, I was happy with pokies organised by category, so I could quickly flick to jackpot pokies in search of my first big progressive win. I’ve still not landed one yet, but you never know what the next spin might hold!
Table games feel like an afterthought at Sloterra. I suppose the name might have given it away - this is primarily an online pokies NZ site, with table games, rather than a casino that focuses on the whole package. A selection of roulette and card games is there for those who like to stick with the tried and tested formats, but it’s nowhere near as impressive as the pokies section or the live dealer section at this casino.
There’s a fine selection of pokies at Sloterra – the vast majority of the games available. I enjoyed the likes of Dead Canary and Book of Wolves Full Moon, but with over 3,500 pokies to choose from, there’s no end to the quality games to be found here. I also liked that it was easy to find the jackpot pokies between the browse and navigation features, so it’s never a struggle if you’re looking for a particular slot to play.
The bulk of the live casino gaming action comes from Evolution Gaming, still the undisputed king of live dealer casinos. With its own dedicated section or live online roulette and blackjack, you can click into the live casino lobby from the left nav bar. I’d say the live offering is better than the RNG table game offering, a strong suit for a casino that seems to be otherwise mainly focused on pokies.
It’s hard to pick a favourite from this 4,000-strong lineup. If I had to choose, I’d probably say Minotaurs Wilds. I enjoyed the theme here, and the high volatility kept me on the edge of my seat. I saw some pretty good wins here too, which is why it sticks in my mind. But generally, there are plenty of good games here to keep you busy.
If you bet on the go, you'll be glad to know there's a Sloterra mobile casino that you can download on Android devices — sorry iOS users, you'll have to wait, but you can of course bet at Sloterra on your mobile simply by using your browser like at most mobile-optimised online casinos.
With only 20 or so providers contributing games here, Sloterra runs the risk of feeling a bit limited in variety. While the 4,000 games are impressive in their own right, I’d like to see more names contributing games to the collection. Still, it’s unlikely you’ll get bored anytime soon, given the sheer quality of the software developers contributing games here.
The likes of Playson, Nolimit City, NetEnt and Evolution Gaming on the live dealer side mean you can be confident of a high-quality playing experience, whatever takes your fancy.
Sloterra has fiat and crypto payment methods available for deposit and withdrawal. As well as Visa, Mastercard, and Neteller, Sloterra is a casino that accepts Skrill. There is also support for payment by Bitcoin, Bitcoin Cash, Litecoin and Ethereum. Withdrawals are processed instantly to crypto and virtually instantly to eWallet payment methods once processing has completed.
The minimum deposit is NZ$10, in line with what I’d expect from most online casinos. The maximum withdrawal is set to NZ$5,000 per day, with limits of NZ$10,000 a week and NZ$30,000. This should only really trouble higher rollers, or those winning jackpot amounts – in which case, I’m sure you’ll be happy to wait a couple of extra days.
Registering your account at Sloterra is straightforward. Follow the simple steps below and you’ll be up and running in minutes.
Sloterra is a safe, trusted online casino. Even though they only launched in 2022, they’re already impressing players worldwide, with some pretty good reviews on forums. Obviously, there are some bad reviews too, but players in general seem to be having positive experiences when they’re winning.
Sloterra uses state-of-the-art encryption to protect players end-to-end, while leaning on the credibility and trust of their Curacao gaming licence. This combination gives a feeling of security and trust when you play with Sloterra.
KYC is required for players depositing over NZ$5,000, or before withdrawal. You need to pass KYC to withdraw, and it can be time-consuming. You’ll need to upload proof of ID, proof of address and potentially further documents to satisfy customer support. For me, this added some delay to withdrawal, so I’d recommend doing it sooner rather than later.
Reach out to complete your KYC requirements as soon as you’ve signed up for your account. Completing this early means you don’t have to wait any longer for your withdrawal — a good way to speed up the withdrawal process when the time comes.
Customer support could probably be a little better. Live chat is available, but only on a limited basis, with operational hours between 9am (GMT+3) and 11pm (GMT+3). For us Kiwis, that’s 12am-2pm – far from ideal! This is one area where they could definitely do more for players, even if the support is responsive and helpful.
Sloterra definitely has its place, especially for players looking to deposit and withdraw in crypto. There’s a good selection of games here, especially for slot fans. Live casino fans are well served here too, with a lineup of games that are definitely worth trying out for yourself. The welcome bonus is decent here too, as are the ongoing promotions, which reward the run of your initial deposits and beyond.
Customer support could be better, and I’d like to see more game developers contributing to the collection. But on the whole, this is a decent casino, and one I have no hesitation recommending for casual players in New Zealand.
I was taken aback at first by the 3x wagering on all deposits. It figures – it’s a strategy to stop money laundering through Sloterra, and probably worthwhile considering it takes crypto payments. But this isn’t the case at all online casinos, and it wasn’t immediately obvious to me on my first deposit. On the plus side, I was impressed by how generous the welcome bonus was, with a very respectable 35x wagering requirement to meet.
The minimum deposit at Sloterra is NZ$10. This is pretty much what I’d expect from an online casino, so I wasn’t too troubled by the minimum. Note that there may be a higher minimum for any welcome bonuses you are offered, typically NZ$20 minimum to qualify.
Withdrawals to cryptocurrency and eWallets are virtually instant after processing. Visa and Mastercard withdrawals are also quick enough, depending on how your bank is set up to receive payments. Processing can take 24-48 hours in some cases, especially where KYC is required.
I have no concerns about safety and data security at Sloterra. It’s fully encrypted and licensed by the authorities in Curacao – not to mention its track record as a trusted, secure place to play. You can play at Sloterra in confidence, knowing it’s fully safe to do so.
Sloterra is a legit casino, with a number of years already behind them. I was able to deposit and cash out without difficulty, and put my trust in the Curacao licence, as well as Sloterra’s reputation, as a legitimate, trustworthy place to play.
The minimum withdrawal is NZ$20, which again sits in line with what I’d expect from an online casino. Before you can withdraw, you must be able to verify your account information by completing KYC. The maximum withdrawal amount sits at NZ$5,000 per day.
Live chat is the easiest way to contact Sloterra when it’s online - between 12am and 2pm daily Auckland time. Alternatively, you can email the support team at support@sloterra.net for out-of-hours enquiries, or for any more complex issues.
