How We Review Online Casinos

We publish our method because a review is only worth something if you can check it. When we say a casino pays out in 24 hours, you should be able to see where that figure came from. When we say a bonus keeps some value, you should be able to follow the arithmetic. Read the steps below, then read the review, and see whether the two match.

One honest frame first. We work from the casino’s own documents, as a New Zealand visitor sees them. That is the evidence, and it is dated. Where our team has run a real-money test, the review shows the date, the amount and the screenshots. Where we have not, it says so. We do not fill the gap with what usually happens.

Seeing the casino as a New Zealand player does

We open each casino from a New Zealand residential internet connection, in a phone-sized browser. That combination matters. A site can serve different pages, offers and currencies depending on where the visitor is and what they are using. A desktop view from somewhere else is not your view.

We save the pages as they are: the terms and conditions, the bonus terms, the promotions page plus the terms behind every offer (the text in the pop-up under each offer card), the payments page with its deposit and withdrawal tabs, the responsible gambling page, and the lobby. Every saved copy carries the date it was taken.

Both sets of terms, read in full

There are always two documents, and the second one is where the trouble lives. The general terms cover the account; the bonus terms cover the offer, and they can overturn what the promotions page promised.

We read both in full. In the bonus terms we look for the wagering multiplier and what it applies to, how much each game type counts, the maximum bet while a bonus is active, any cash-out cap, whether you must wager your own deposit before withdrawing, dormancy fees, and the dispute clauses, including any wording that gives the casino the final say. If a document cannot be captured, we say so rather than guessing.

The licence, checked at the regulator

A badge in a footer proves nothing. We follow the licence seal to the regulator’s own certificate or register page and compare it with what the casino claims: company name, company number, licence number and the domain named on the certificate. Then we check the status.

An example: on 10 Oct 2026 the Curaçao Gaming Authority certificate for slotlounge.com showed Stable Tech N.V., licence OGL/2024/161/0191, status Active. That is what a checkable licence looks like. A seal that leads nowhere near the regulator counts against the casino.

The cashier, as listed for New Zealand

We record the payment methods, minimums and payout times the casino lists for a New Zealand visitor, then compare them with the payment logos in the footer. The two often disagree, which is useful in itself. A logo wall is marketing; the payments page is the instruction sheet.

Payout times are the casino’s published figures unless a review says we timed a withdrawal ourselves. If we did not sit with a stopwatch, we do not write a number as though we did.

What a bonus is really worth

Headline numbers tell you nothing, so every welcome offer goes through the same test. We put NZ$100 – or the offer’s minimum deposit if that is higher – through the offer exactly as its terms read.

Turnover is the wagering multiplier times the amount it applies to, adjusted for how much pokies count. Pokies return about 96% on average, so every NZ$1 wagered costs about 4 cents. Bonus minus that cost is the value left. Four verdicts cover the result: keeps real value (25% or more of the bonus survives), roughly break-even (0-25%), costs a little more than it gives (down to -50%), costs much more than it gives (below that). It is an average, not a forecast.

Three more figures go on the page: how many NZ$1 spins a day the expiry period demands, the biggest bet allowed, and any cash-out cap. Run your own numbers with our wagering calculator.

The 12-point check

Every review carries a score out of twelve, written like 7/12. Each point comes from a yes/no question answered only from published documents, and one point is awarded for each answer in the player’s favour. The list is fixed for every casino.

• Is the licence shown as active on the regulator’s own site?
• Are the operator, company number and address published in the terms?
• Is New Zealand absent from the restricted countries list?
• Are the rules free of one-sided wording, including a final say in disputes?
• Is an NZD account available?
• Are there no casino fees on deposits or withdrawals?
• Are withdrawals processed within 24 hours, as a published figure?
• Is there no rule requiring you to wager your own deposit before cashing out?
• Does the welcome bonus avoid costing more than it gives in the NZ$100 test?
• Is there no cash-out cap on winnings from the welcome bonus?
• Do the offer card and the bonus terms describe the same offer?
• Are deposit limits, breaks and self-exclusion explained publicly?

An unclear answer scores nothing until the casino clarifies it in writing. A missing document is not a pass, and we would rather show a low score than a generous guess.

Screenshots and quoted clauses

Numbers and scores are only as good as the evidence under them, so clauses that change the deal are quoted word for word, with the clause number and the date we read them. If a sentence decides whether you can withdraw, that sentence goes on the page.

Key clauses, offer terms, the withdrawal tab and the regulator’s certificate are shown as screenshots taken from a New Zealand connection, each captioned with its date.

What every review admits

Each review ends with a “what we could not check” list. Support response times, how long ID checks take in practice, and the settings inside an account we did not open cannot be seen from outside, so they are listed as unknown.

The same honesty applies to testing. When our team has made a real deposit or withdrawal at a casino, the review shows the date, the amount and the screenshots. When we have not, the review says that too. We never describe a test we did not run.

Re-checks and changes

Terms move. We capture the documents again, compare them with the previous copy and note what changed.

A recent example: Slot Lounge added a bonus clause, 2.11, on cancelling an active bonus, between our captures of 28 Sep and 10 Oct 2026. The review now quotes it.

If you spot an error, tell us through the contact page and we will fix it on the page and update the document date.

Money and independence

Spintown.nz earns affiliate commissions when a reader opens an account through our links. That pays for the work; it does not change any number on a review page. The value test, the 12-point score and the quoted clauses come from the casino’s own documents. Review pages show a disclosure next to the casino link.

Positions are not for sale, and no operator can pay to remove criticism. For the legal background on where these sites sit for New Zealand players, see our gambling law page. For the reviews themselves, start with online casinos for New Zealand.
