Welcome to our main casino review library!

Here are all our reviews catalogued and stored. But you’re probably wondering – how do we rate and review all these casinos? Today, we want to explain exactly that. We’ll go into detail about our review criteria, what we prioritize and what online casinos to avoid.

Here you can search for any NZ casino review or scroll down to find them all listed.

What Is an Online Casino Review?

Online casino reviews are assessments of casinos in real time. Instead of just looking up the information, our reviewers become players and test these sites. The casinos don’t know our profession, so we get the same treatment as you. This gives us complete insight into how the site treats players regarding disputes, seemingly dumb questions and other issues.

When reading casino reviews, you should first pay attention to the review date. If a site was great in 2020, that doesn’t automatically mean they kept investing in new games and features. That’s why we update our reviews. Our team is also unafraid to knock down a site's ranking if we’re not satisfied with how things are going.

But what exactly goes into our online casino reviews? What makes a casino good or bad?

Review Criteria: What We Look for in Online Casinos

A better question would be: what do all the best online casinos have in common? Even though personal preferences are still important, the following aspects of casinos are universal:

License

We only review legal casinos. This means they have to be ed with a country’s gambling regulator. To get this form of approval, the operator has to submit an application, undergo an audit and pay a fee. Also, they have to respect specific standards and laws. Our experts immediately scan the site for regulator logos and check the licensor’s public registry to find proof.

Restricted Countries

Whenever we review a site, we want to know where it’s legally available. This also involves currencies, regional payment methods and other aspects of localization. We immediately point out restricted countries so our readers won’t waste time. We update the list if the site applies for a new license (or loses an old one).

Game Library

Obviously, this is the central part of each review. Every player deserves to have thousands of choices, and we make sure to point our readers in the right direction. What we like to see is a well-organized lobby. Games should be split into categories with tags and different filtering options. There should be at least several hundred slots from providers of all sizes. Table games and live dealer tables also affect the final score, but only if they come from reputable studios.

Mobile Play

The mobile gambling market is expected to reach $154 billion globally by 2030. And it’s no surprise, given how casinos invest in mobile apps. Our experts look for cleanly-designed software that’s not too different from the desktop site but also not a recycled UI. Everything has to work smoothly on both iOS and Android devices.

Security Features

Online casinos have a lot of daily revenue, making them ideal targets for hackers. That’s why the best sites invest in SSL encryption, firewalls and even third-party audits. If a site has all these things, it means they care for its players and don’t want a data leak on its hands. To be extra sure, we also research how strict the regulator is about security.

📙 Erik King’s Quick Tip: Some offshore casinos claim SSL encryption but don’t force HTTPS across all pages, before g up, try accessing the site with just “https://” instead of “https://”. If it loads, your data isn’t fully protected. Walk away, legit casinos hard-block insecure connections.

Nowadays, people like to play games throughout the day. So when writing our online casino reviews, we want to see available beyond the standard 9-5 working hours. Ideally, there should be 24/7 availability through email, live chat and phone. The top sites even answer messages on their Facebook and Twitter s, too.

-Friendliness

And last but not least, our team wants to determine how welcoming the site is for new players. Sure, some things seem normal to us veterans, but we’re looking for the best and most convenient solution. This includes UI design, loading times, colours and everything else that’s involved in the day-to-day use of the casino.

Other Things That Affect Our Casino Reviews

Besides the pillars of our scores, we also like to focus on these ‘less glamorous’ aspects of an online casino:

  • Deposit and withdrawal methods. Banking may not be the main part of a site, but it’s your first impression and a section you can avoid. We prefer sites that offer a mix of global and local payment methods.
  • Transfer limits. No one likes to be restricted, whether it’s for safety or some other reasons. The Zamsino team looks for casinos that treat everyone equally from the start.
  • VIP Programs. Players are under no obligation to play at just one site, so they deserve compensation for their loyalty. The best online casinos offer custom bonuses, weekly cashback and even an manager to those who play the most.
  • Available languages. Not everyone is a native English speaker, and they deserve to feel comfortable whilst playing. The entire site should be able to change languages, including the UI of every game in the lobby.
  • Currencies. To avoid exchanges, players should play at sites that accept multiple currencies. This allows you to use something you need on a daily basis without needing to pay an exchange fee to your bank later on.

📙 Erik King’s Quick Tip: Some casinos with multi-currency wallets let you switch your currency once, usually during your first deposit. If allowed, choose a weaker currency with the same nominal bonus (e.g., 100 EUR = 100 NZD) to get a bigger real-money edge. Then switch back to your preferred currency for play.

What to Avoid in Online Casinos

Generally, you should stay away from unlicensed sites and those that often change their name. This is a sign of shady business dealings, more often than not. Also, look for bonuses that seem too good to be true. Ask yourself – why would a site offer thousands of dollars to everyone, just like that?

Don’t hesitate to follow our testing methods as well. You can ask for and research the casino’s owner and history. It is, after all, our goal to educate readers and allow them to recognize fraudulent sites on their own.
