Expert Review

One Casino is a top-rated online casino that offers a truly rewarding gambling experience to Kiwis. The casino values and understands quality gaming and thus brings the most exclusive gaming library, bonuses like no other, and many other features that are designed carefully, keeping the needs of gamblers in mind. The most exciting part of One Casino was their no-deposit $10 bonus, which is quite unique, as not many casinos in NZ offer this.  That was enough to make me sign up, and I checked out the gaming catalogue to discover more than 500 titles. There were pokies, jackpots, table games, live dealer games, and much more on offer to explore and play.

The banking options for Kiwis at One Casino were limited, but all were secure and fast for both deposits and withdrawals. The live chat support is very quick in providing a solution. One Casino also takes security seriously and is fully encrypted and licensed by the relevant authorities. To find out more, let's discuss all of the features of One Casino in this review.


  • Exclusive range of slots, table games, poker, live games, and more
  • All top game providers are available
  • No-deposit welcome bonus and many regular promotions
  • Mobile-friendly casino
  • Instant live chat customer support


  • Few banking options

Games: 9.5/10

One Casino has one of the best collections of premium casino games for Kiwis to enjoy exclusive, entertaining, popular, and classic titles. Their gaming catalogue consists of around 500 games, which I initially thought was lacking compared to casinos offering thousands of games. However, my entire perspective changed once I found out who One Casino has partnered up with to source those games.

One Casino is a quality-centric gambling platform that ensures every single game they offer works smoothly and flawlessly on all types of devices. And for that, they have partnered up with some of the most popular game providers in the gambling industry. All the big names like Evolution, NetENT, and Pragmatic Play are available at One Casino and they consistently provide new titles and update existing ones.

What I loved the most about One Casino was their diverse gaming library. The casino brings all types of popular and in demand casino games. It doesn't matter if you have a knack for slots or you are a poker player; you will be very well taken care of. Not only that, I also found many table games, card games, bingo, and live dealer games, with each category having a considerable number of titles to play. The homepage also had new releases, hot games, and exclusive titles that only One Casino players have access to. And if you are looking for a very specific title, there is a search bar that helps you fetch any game by entering a keyword. I was also able to filter the games by selecting a game provider of my choice.

I did not bother filtering the games and simply started playing different titles by visiting different sections. I spent two whole weeks at One Casino playing slots, jackpots, poker, and a few other types of games to get a good idea about how things work there. Upon clicking on any title, One Casino would provide me with some info regarding what the game is about, its release date, and its developer. I was able to play all of the games at One Casino in demo mode, except for the live dealer games, which required real money to start betting.

However, there was one minor issue which bothered me; there was no option to enter fullscreen mode, which I prefer. I had to play all the games in windowed mode, which doesn't affect gameplay, but it means the games were not as immersive. Other than that, the games were very fast to load, and I never had to wait more than a few seconds for the interface to appear.

The in-game interface was really user-friendly; I could switch between different game modes where available, place customised bets, or set up the preferences myself. Not only that, each game had premium, realistic, and eye-catching graphics, making the environment engaging and fun. I also loved the addition of music in the games, along with the themes. As for the gameplay, I always had a lag-free gaming experience at One Casino without the common problems of stuttering or freezing. On top of that, all live games were pretty fun to play. The live streaming was smooth, in HD quality, and without any buffer. The live agents were friendly, chatty, and created an immersive and real-life gambling environment.

Bonuses: 9.8/10

I have reviewed countless online casinos offering their players a welcome bonus on making the first few deposits at the casino. However, it is rare to find an offer like One Casino’s where you can get $10 in bonus credits for simply signing up. The no-deposit welcome bonus is available for all New Zealanders and can be used with a variety of games at the casino. However, that is not all I was offered at One Casino! There was another welcome bonus that I could claim by making my first deposit. One Casino offered me 100% up to $200, which I could claim and withdraw, keeping their terms and conditions in mind.

No deposit welcome bonus

  • Sign up - $10 in bonus credits

Welcome Bonus

  • 1st deposit - 100% up to $200

One Casino had a minimum deposit requirement for their welcome bonus, which was $10. I had to wager the bonus 35 times in order to be eligible for withdrawal. The same wagering requirements also apply to the no-deposit welcome bonus and must be completed before players can request a withdrawal. Keep in mind that not all games at One Casino contribute the same to fulfilling their wagering requirements. Slots and video slots contribute 100%, while table games and games provided by NetENT and Play’N Go contribute 10%. 

Players who are planning to stay at One Casino have a wide range of regular promotions to avail of. There are weekly deposit bonuses that offer anywhere between 25% to 100% bonus to their players. They also have cashback deals, exclusive promotions, and even a loyalty program, which comes with a range of benefits. I discovered that their loyalty program had seven different levels. I simply had to accumulate more points by playing more at the casino and climbing the levels to enjoy more perks and benefits.

Deposits and Withdrawals: 9.1/10

If there is one thing I would want to see improved at One Casino, it is their banking department. As a New Zealander, I was not provided with a lot of payment options. The very limited options were bank cards and a few e-wallets. There is no support for cryptocurrencies or mobile wallets like Google Pay or Apple Pay. On the positive side, One Casino did not charge me any fee when I made a deposit at the casino. It was the same for withdrawals, as no service fee was charged to my account.

All deposits at One Casino are processed instantly. I made a deposit with my Visa card and initiated a transaction of $100. Upon entering all the details and proceeding with the transaction, it was instantly approved, and I received funds in my account within seconds. For the complete list of payment options at One Casino, you can take a look below:

Deposit methods

  • Visa (Min. $10)
  • Mastercard (Min. $10)
  •  Skrill (Min. $20)
  • Paysafecard (Min. $10)
  • MuchBetter (Min. $10)

Withdrawal methods

  • Bank withdrawal
  • Visa
  • Mastercard
  • Skrill
  • MuchBetter

Note that One Casino processes withdrawals to the same payment methods players used to make the deposits. Also, I had to get myself verified by submitting my identity documents before I could be eligible to receive withdrawals. One Casino does it to prevent identity theft and create a safe environment. Withdrawal limits vary and can take up to two working days to process.

Mobile Gaming: 9.6/10  

One of the perks of choosing One Casino as your primary gambling destination is that you are not limited to laptops or desktop computers only when it comes to gaming. If you have a phone with a working internet connection and a browser, you will be able to play at One Casino without any problem. I accessed One Casino from my mobile using the Chrome browser as its interface suits me, and I think it works great for HTML and online games. Upon accessing the site, I logged into my account to get access to the funds I had already deposited. However, I also had the option to make deposits or withdrawals right from my phone, check out bonuses, or change the account preferences as per my liking.

The entire gaming catalogue of One Casino was also available for me to explore. The homepage had different small sections covering new, popular, exclusive and some other titles, and I could also visit the games section and choose dedicated categories from there. I tried some slots first and then also played jackpots, bingo, and live dealer games. My phone, despite being 3 years old, handled all the games quite easily. It never froze, and the device temperature remained normal. I had a few long gaming sessions on my phone, and I always loved the crystal-clear graphics, easy navigation, excellent-quality sound, and everything there was to offer. The live dealer games also worked flawlessly without any buffer, thanks to my stable internet connection, which played an important role in that.

In other words, mobile users at One Casino get to enjoy the same gambling environment and features as computer users do. They can contact support, access their account settings, claim bonuses, manage banking, and play games all day long without any restrictions.

Customer Support: 9.8/10  

I never had a problem getting in touch with One Casino representatives and always had a hassle-free experience. The casino offers 24/7 live chat support that answers your questions almost instantly. To use it, I only had to click on the support icon that was available at the lower-right corner of my screen. Upon doing so, a popup appeared where I had to enter my name and email address and then proceed by clicking on start chat. I was then connected with an agent who asked my question and then provided me with the details I needed. I could even send in pictures through the live chat support in case there was an error on my screen or a problem that couldn’t be described in writing.

Moreover, One Casino also allows the players to contact them via email. I visited the help centre, and from there, I could fill out the form, attach the screenshot, select the date and game, and send in my query. Not only that, the help centre also had a lot of FAQs, short guides, and articles that I could check. It saved me a lot of time as I was able to answer most of my questions from there.

Security and Licensing: 9.8/10  

One Casino is a brand of its own and is not owned by any third-party company. The casino is based in Malta and has also provided their physical registered address of the country in the footer of the website. One Casino is licensed and authorised by the Malta Gaming Authority, and they also have the official licensing certificate from MGA. I attached the certificate below for you to take a look at and confirm that One Casino is a legitimate place to play at. Additionally, One Casino also has authorisation from eCOGRA, which indicates that all the titles at the casino are fair and safe to play.

One Casino has SSL encryption on their site, which is the latest security measure to keep the site safe from hackers and breaches. They also leave it up to their users how they secure their accounts. For instance, I made sure to set up a very strong and unique password for my account, change communication preferences, set up 2FA, and even got my phone number verified.


As a perfectionist who doesn’t compromise on my gambling experience, I loved every minute I spent at One Casino. The casino prioritises quality over quantity. Although they only have around 500 games, all of them are optimised, entertaining, fair, and top-notch. The games run flawlessly on different devices, come with excellent graphics, and do not lag. On top of that, One Casino treats their players with a no-deposit welcome bonus, which is extremely rare to find nowadays. Additionally, you get to enjoy a separate 100% match bonus, regular promos, and much more to keep yourself entertained.

However, One Casino could improve their banking services by adding more payment methods for Kiwis. Other than that, the casino is a licensed entity and adheres to all legal requirements. You can gamble in a safe environment and delve into the world of premium gambling.
