How We Test.
Most casino ranking pages are ordered by commission and justified afterwards. This page sets out the calculations we run instead, the sources we accept, and the conditions under which an operator is removed regardless of what it pays.
Key figures
- 25x the wagering level above which a bonus on a typical 96% slot costs more to clear than it releases
- 12 of 15 operators removed during assessment of the most recent deposit tier we covered
- 0 of 53 external links across our deposit cluster carrying a tracking parameter
We earn commission when a reader opens an account through a link on this site. That is the entire business model and it is worth stating plainly, because a page claiming independence it does not have is worse than one that discloses. What commission cannot do is change a ranking, add an operator, or remove one — the mechanism that makes that true is set out under commercial relationships below.
The one calculation behind every ranking
A wagering requirement forces you to turn a bonus balance over a fixed number of times before it can be withdrawn. Each unit of that turnover surrenders the house edge, which is one minus the game's return to player. Multiply the two and you get the expected cost of completing the requirement, expressed as a share of the balance you are trying to release.
Set that cost equal to the balance itself and the equation resolves to a single threshold: the break-even wagering multiplier, which is 1 divided by the house edge.
| Published RTP of the eligible game | Wagering above which clearing costs more than it releases |
|---|---|
| 97.20% | 35.7x |
| 96.00%, roughly the market average | 25.0x |
| 94.92% | 19.7x |
Break-even = 1 ÷ (1 − RTP). Assumes full game weighting and play confined to the eligible title. Restricted games, partial weighting and maximum cashout caps all move the real threshold down, never up.
This is the number we run against every offer before writing a word about it, and it is why our pages routinely conclude that an offer is not worth taking. Almost every welcome bonus in the New Zealand market sits above its break-even threshold. Saying so is not scepticism for its own sake — it is what the operator's own published figures produce when you multiply them together.
Why we read the base before the multiplier
The wagering figure an operator advertises is meaningless until you know what it multiplies. Two conventions are in common use and they invert the ranking.
| Stated terms on a NZ$20 deposit with a 100% match | Turnover actually required |
|---|---|
| 40x applied to the bonus alone | NZ$800, or 40 times the bonus |
| 35x applied to bonus plus deposit | NZ$1,400, or 70 times the bonus |
The lower headline figure demands 75% more work. Free spins attached to the same offer are usually wagered under a third rule again, which we have seen range from 1x to 45x on packages advertised identically.
So every offer gets three numbers recorded rather than one: the multiplier on the cash bonus, what that multiplier applies to, and the separate multiplier on free spin winnings. An operator that publishes a low headline figure against the heavier base ranks below one publishing a higher figure against the lighter base, and we show the arithmetic rather than asserting the conclusion.
The three tiers of source we accept
Every number on this site carries a source, and sources are not equal. We work down this order and record which tier each figure came from.
| Tier | What it covers and how we use it |
|---|---|
| Primary | Regulator registers and legislation, the operator's own terms and payments pages, and game providers' published RTP, volatility and stake data. Quoted directly |
| Secondary | Public complaint records at named mediation services, national consumer bodies, peer-reviewed research and quality business press. Quoted with attribution to the source by name |
| Pointer only | Competing affiliate listings and aggregators. Used to locate a primary source and never cited as the basis for a figure |
Where two sources conflict, we publish the conflict rather than picking one. Several pages on this site carry an unresolved discrepancy for exactly that reason.
Two rules sit on top of that hierarchy. First, currency is part of the figure: a €20 threshold is not a NZ$20 threshold and we do not transcribe one as the other. Second, a terms page served on a lookalike domain is not the operator's terms — we have found three different operating companies named across domains carrying a single brand, and we now read the company name, registration number and licence number on the exact domain before quoting anything from it.
The 6 conditions that disqualify an offer
Any one of these 6 removes an operator from a page, whatever the commercial arrangement. Each is checkable by a reader in under 2 minutes, which is deliberate — a criterion you cannot verify yourself is a criterion you have to take on trust.
| Condition | Where a reader can verify it |
|---|---|
| Wagering exceeds the break-even multiplier for the eligible game by a wide margin | Bonus terms for the requirement, provider's game page for the RTP |
| The offer does not name the eligible game, so no threshold can be calculated | Bonus terms — an unnamed game is itself the disqualifier |
| The qualifying threshold is published in a currency other than the one the page is about | The promotion page, read for currency symbols rather than numbers |
| Minimum withdrawal is set well above the minimum deposit | Cashier or payments page, per method |
| A public, dated complaint record shows withdrawals stalling past the operator's own stated window | Named mediation services listed in our sources |
| Operating company or licence number in the footer does not match the terms page on the same domain | Footer and terms, side by side |
Independent safety ratings are read as a further input rather than a rule. A rating that contradicts our own findings is published alongside them, not suppressed.
What removal looks like in practice
A methodology that never excludes anybody is decoration. On the most recent deposit tier we covered, 15 operators were assessed and 12 were removed before publication.
| Ground for removal | How many |
|---|---|
| No published terms locatable from any independent source | 5 |
| Qualifying threshold in the wrong currency or above the tier | 4 |
| Independent safety rating in the lowest band, or an unresolved withdrawal dispute on file | 2 |
| Wagering base making the real requirement the heaviest in the set | 1 |
Counts from the assessment published on our NZ$20 tier page, where each removal is named with its reason.
Separately, 2 operators are excluded from every list on this site rather than from a single page, on the basis of public complaint records showing withdrawals stalling past the operators' own stated processing windows and self-exclusion requests not being honoured. Those exclusions are named, dated and sourced on the NZ$1 deposit page.
What we will not publish
These are commitments about our own output rather than claims about operators, and they are the ones worth holding us to.
We do not invent figures. No estimated numbers, no plausible-sounding approximations, no numbers included for the appearance of rigour. Where a figure cannot be sourced, the section is rewritten around one that can, or the gap is stated.
We do not invent sources. No citation to a study, regulator, author or report whose existence and content we have not confirmed. In a market where this happens routinely, a fabricated citation is more damaging than a missing one.
We do not claim tests we have not run. Language asserting a hands-on deposit, a stopwatch on a withdrawal or a verification carried out by us appears only where that physically happened and a record of it exists. Everything else is described as what it is: a calculation from published terms, or a report from a named source.
We do not sell placement. An operator cannot pay to be added, removed, or moved up a list. Rankings are set before commercial terms are discussed, and 0 of the 53 external links across our deposit cluster carry a tracking parameter, which is a claim you can verify by inspecting them.
We do not promise outcomes. No system, no strategy, no offer described as beating the house. Every bonus we cover is negative in expected value and each page says so.
How often the figures are re-checked
Facts on this site are classified as stable or volatile at the point they are written, and the two are handled differently.
| Class | Treatment |
|---|---|
| Stable — legislation dates, licence jurisdictions, a game's published RTP and stake floor | Reviewed on the page's general cycle |
| Volatile — bonus sizes, wagering, deposit and withdrawal minimums, cashout caps, licence status | Carry a visible check date and are re-verified every 30 days |
A volatile figure without a check date is a defect on our side. In this market, terms change quietly and a page asserting a superseded wagering requirement is a factual error rather than a cosmetic one.
Every page also carries the same standing instruction, which overrides everything else we publish: where our figure and the cashier disagree, the cashier is correct.
Corrections and right of reply
Before publishing a named criticism of an operator, we put the specific claims to that operator in writing and allow 5 business days for a response. A reply, or the absence of one, is recorded on the page.
Any operator may contact us with evidence at any time. Where the record warrants it we publish a correction on the page itself rather than quietly editing it, and where a rating or complaint file has since changed we say so and re-date the section. Ratings and complaint records quoted on this site are dynamic; a figure read in July may not hold in October, and we treat that as our problem rather than the reader's.
Who writes and who checks
Three people carry named responsibility for what appears here. Credentials are set out on each author page rather than summarised in marketing language.
| Name | Role on this site |
|---|---|
| Joseph Buchdahl | Expected value, wagering arithmetic and the break-even framework used across the deposit cluster |
| Paul Krishnamurty | Editorial review, market context and the operator assessment framework |
| Josh Appelbaum | Fact-checking, source verification and the 30 day re-check cycle |
Bylines record responsibility for the content beneath them. We do not attribute quotations to authors that they have not given, and a name appears in a review field only where that review actually took place.
Commercial relationships in full
We are paid by operators on a commission basis when a reader opens an account through our links. Two structural rules keep that from setting the order of a page.
First, ranking criteria are fixed before commercial discussion, and they are the ones published above rather than a private set. Second, the disqualifiers are absolute: an operator meeting any of the 6 conditions is removed whatever it pays, and the pages showing 12 removals from 15 assessed are the evidence that this happens rather than being asserted.
What we cannot claim is independence from the industry itself. We are an affiliate site and our revenue rises when readers deposit. The honest version of that is this: read our arithmetic, check it against the cashier, and treat any page that never tells you to skip an offer — including ours, if it ever stops doing so — as advertising.
Where this method is applied
The clearest worked examples sit across the 6 pages of our deposit cluster, where the same calculations are run against the same 3 offers at every tier and reach different conclusions at each.
