King Billy Casino Review NZ

Expert Review

King Billy is hands-down one of the most diverse online casinos I have ever reviewed. The platform has been in business for half a decade now and has earned a good reputation among New Zealanders for their premium features. An ideal casino for any online player, King Billy combines a massive gaming library that boasts more than 5,000 titles, irresistible bonuses, latest banking options, and the best possible support in a single place.

The gaming library is King Billy’s biggest attraction; not only do they offer an extensive range of pokies, but they also have card and table games, progressive jackpots, live casino games, and much more. With constant updates to the library and new additions, King Billy makes sure their players get the absolute best. They have games from many of the top game studios, ensuring their players get the best possible gaming experience, whether on computer or mobile.

Upon my first visit, the casino offered me a generous welcome bonus of $2,500 as well as 250 free spins that I could claim across my first four deposits. I also found many ongoing promos that regular players can check out. In this King Billy review for New Zealand, I take an in-depth look into their games, bonuses, banking, and security, and share my experience with all of their features.

Games: 10/10

King Billy is among a few online casinos with a gaming library of more than 5,000 premium casino games. They cover all the casino gaming categories, so players with different preferences can enjoy the experience.

New, top, and popular games have their own dedicated categories at King Billy. There are also separate sections for slots (which are further divided into subcategories), table games, live casino games and jackpot games. No matter what category I clicked on, I found hundreds of choices. King Billy also provided me with a complete list of more than 50 game providers, including Playson, NetENT, Quickfire, Play’N Go and many others, which are among the best developers. King Billy also enables players to filter their search results by selecting a game provider or using the search bar to find a particular title.

Using my laptop, I played a few titles from each category to check the overall performance of the games. I loved the option to play games in demo mode and use virtual funds just for fun. I also made a deposit at the casino, so I could play games to win real money. The games performed exceptionally well, and I had a smooth gaming experience.

The games loaded quickly, taking around ten seconds, and I was able to play all the games at high frame rates without any stutters or freezing. The in-game interface was really easy to navigate, and I loved the advanced layout with several features. I could enter full-screen mode, mark favourites, find the latest winners, and switch to a different game in an instant.

The graphics were also top-notch and high-quality. Each game had an interesting theme, great music score and eye-catching animations, making the experience even more fun. When I switched to live casino games, there was a whole new world to explore. The inclusion of professional dealers, the ability to chat with others and watch live streams gave the vibes of an actual casino, making me appreciate the unique experience even more. You can also try live casino games, but I would recommend having a stable internet connection so the live streams won’t lag or buffer on your device.

Bonuses: 9.7/10

King Billy definitely knows how to attract new players and keep their existing players happy. When I signed up at the casino, I was offered one of the biggest welcome bonuses I have seen in my gambling career. Upon making a deposit with NZD, King Billy offered me up to $2,500 as well as 250 free spins as a welcome bonus. However, note that this was divided across the first four deposits I would make at the casino.

On my first deposit, I received 100% up to $500, along with 100 free spins. The second deposit could get me 50% up to $500 and 50 free spins. The third deposit offers 25% up to $1,000, and the fourth deposit rewards 75% up to $500 as well as 100 free spins. I claimed the first deposit bonus right away by making a deposit of $100. I got $100 in bonus credits, and the 100 free spins were credited to my account instantly.

There is also a separate welcome bonus for anyone who makes their first deposit with crypto. Players can get 100% bonus up to 1 BTC and 250 free spins as a welcome deal, which is massive, considering the price of Bitcoin today.

There are a few terms and conditions regarding the welcome bonus at King Billy that one should keep in mind. I had to wager the welcome bonus 30 times in order to cash out my winnings. I was given 30 days to fulfil this requirement for the match bonus, but only 7 days for the free spins. I completed the wagering requirements within a few days and received my winnings later on in my bank account. The minimum deposit required to trigger the welcome bonus is set to $10, which will not be a problem for most players. 

I found a number of deals for regular players in the promo section. King Billy offers a 15% cashback on all deposits every Thursday, allowing you to have extra funds to play with. I also loved the 100 free spins deal on Book of Dead that is available every day and can be claimed by making a deposit of $150 or more. VIP players are treated with extra perks and excellent offers available throughout the year. I also recommend following King Billy on their social media accounts as they offer exclusive deals that their followers can claim.

Deposits and Withdrawals: 9.7/10

King Billy has one of the best payment systems in place for New Zealanders. When I decided to make my first deposit at the casino, I had the option to use all the popular credit and debit cards, e-wallets or vouchers or make a crypto transfer. King Billy supports all popular cryptocurrencies, including Bitcoin, Ethereum, and USDT. They are among the few online casinos to have brought the option to deposit, withdraw and play with cryptocurrencies.

As I was out of funds in my crypto wallet, I decided to use my Visa debit card. I deposited $100, entered my secure OTP, and the transaction was processed smoothly. King Billy does not charge any fee on deposits or withdrawals, and all transactions are processed instantly, except for bank withdrawals. However, crypto deposits or withdrawals might incur a miner fee that is beyond the casino’s control. Take a look below to find out the payment methods available at King Billy:

Mobile Gaming: 9.6/10  

King Billy does not have any official mobile apps, but their mobile-optimised website works for any smartphone, so you can play any casino game wherever you like. I opened the Chrome browser on my Android smartphone, and searched for King Billy. The first result redirected me to their mobile website where I was able to log into my account instantly. I found the layout and interface quite similar to the desktop version, which was a good thing as I was already familiar with it. The site was easy to navigate and explore, and different features had their own dedicated sections.

I visited the gaming lobby right away, which gave me access to thousands of games that I could play from my phone. I tried some slots and then moved on to jackpot games and table games. The site was blazingly fast, even for mobile devices. All the categories opened instantly, all the games loaded fast, and the games never stuttered. I played all the games in fullscreen mode, and the graphics were as amazing as ever. The gameplay was also smooth without any connection-loss issues, lag or freeze.

After thoroughly testing the games, I visited other sections of the casino to evaluate what is available for mobile players to access. I could make deposits and withdrawals, check out the promos section, claim bonuses, contact support and do anything a desktop user can. Overall, I loved my experience playing on mobile at King Billy. Just make sure to have a stable connection and an updated phone browser for a seamless gaming experience.

Customer Support: 9.9/10  

The customer support at King Billy is amazingly efficient and quick. They have guiding content, AI bot, live agents and email support that you can use to solve any problems. When I need assistance, I prefer chat support as it is always the quickest and most convenient option. I clicked on the chat button, and a small popup appeared. I clicked on the messages and was welcomed by an AI bot which was designed to answer specific types of questions related to particular categories. I could also request a live agent, which I did and was connected to one right away. I asked several questions, and was answered professionally and in detail every single time.

Players can also send an email to King Billy or contact them on Facebook and Instagram. King Billy brings a lot of guiding content as they have separate sections for news, blogs, FAQs, terms and conditions, and even policies.

Security and Licensing: 9.7/10  

King Billy operates under a licensed and registered company known as Dama N.V. which is based in Curacao where it has a physical office. The company has a valid e-gaming licence from Antillephone N.V., an entity authorised and regulated by the government of Curacao. This licence also authorises King Billy to provide gambling services in New Zealand and several other jurisdictions. All the games at the casino are safe and fair, and utilise the industry standard RNG system which is solely based on the luck of the player.

King Billy uses SSL encryption and other latest security integrations on their site. Players are also provided with many account security features to secure their accounts. I recommend setting up a unique password and enabling 2FA and email alerts for quick updates. King Billy verifies all the users at their casinos to reduce fraudulent activity and money laundering. All these precautions create a safe environment to play in.
