How we rate casinos
Every score on this site is calculated, not chosen. Here is the entire formula, the reasoning behind each weight, and what we do when we cannot verify something.
Written and checked by the Casino Insider editorial desk · Last reviewed 17 September 2026
The formula
Each casino is scored from 0 to 10 on five pillars. The overall score is the weighted mean of those five numbers, rounded to one decimal place. That is the whole calculation — there is no adjustment afterwards.
We publish the pillar scores on every review page alongside the overall, so you can check the arithmetic and, more usefully, disagree with our weighting. A player who only cares about live dealer should mentally re-weight the catalogue pillar upwards and read the list differently. We would rather give you the components than ask you to trust a single number.
What each pillar measures
Rand handling — 25%
What we look at: Whether the account holds rand from deposit to withdrawal, or whether your money is converted on the way in and again on the way out.
Why it carries this weight: A conversion spread of two to three percent each way costs more over a year of play than almost any bonus difference gains you, and it is invisible because it never appears as a fee. This is the single biggest hidden cost in South African online casino play, which is why it carries the joint-heaviest weight.
Banking — 20%
What we look at: Which South African payment rails actually work: instant EFT, Ozow, SID, Capitec Pay, FNB eWallet, cards, vouchers.
Why it carries this weight: An operator that only takes cards excludes a large share of South African players outright, and forces everyone else through the slowest rail available. Breadth here is a genuine measure of whether a site was built for this market or merely accepts it.
Payouts — 25%
What we look at: How long withdrawals take to clear, what the caps are, and how the verification process behaves in practice.
Why it carries this weight: Getting money out is the only part of the transaction the operator has any incentive to slow down. It is weighted equally with rand handling because a bonus you cannot withdraw is not a bonus.
Catalogue — 15%
What we look at: How many software suppliers are in the lobby, and whether live dealer tables are genuinely available.
Why it carries this weight: Most rand-facing casinos run a single supplier, which caps what you can play regardless of how good the banking is. We weight this lower than money handling because the difference between a good catalogue and a great one matters less than losing three percent on every transaction.
Support — 15%
What we look at: Whether support runs in South African hours, which channels exist, and whether anyone answers them.
Why it carries this weight: It only matters when something has gone wrong — but when something has gone wrong it matters more than everything else on this list combined.
Verifying welcome offers
Bonus figures are the most frequently fabricated numbers in this industry. Comparison sites copy them from each other, the original was often wrong, and nobody re-checks. We do not publish a figure unless we loaded it ourselves.
Our process is deliberately dull. We follow the sign-up link exactly as a player would, land where the player lands, and read what that page says. If it says 150% up to R1,000, we print 150% up to R1,000 and record the date. If the page is geo-blocked, dynamic, or resolves somewhere unexpected, we print no figure and explain the gap on the review page.
6 of our 9 ranked casinos currently carry a verified figure. The remaining 3 do not. We consider that gap a feature of the method, not a failure of it.
What we do not score
We do not publish return-to-player percentages for casinos. RTP is set per game by the software supplier, not by the operator, and a site-wide "96.4% payout" figure is not a measurable property of a casino — it is a marketing number. You will find those figures on most comparison sites. You will not find them here.
We also do not count games. Catalogue size is trivially inflated by counting regional variants of the same title, and a lobby of 300 well-chosen slots beats 2,000 duplicates. We score the number of suppliers and whether live dealer genuinely exists, because those are the things that change what you can actually play.
Conflicts of interest
Casino Insider earns commission when a reader opens an account through a partner link. Every such link is
labelled on the page it appears on and carries rel="sponsored" in the markup.
The safeguard against that money distorting the rankings is structural rather than a promise: the score is computed from published components and the components are printed next to it. Our directory marks every brand we earn nothing from, so the boundary of our commercial relationships is visible rather than asserted.
What we do when we have no link
Most operators marketed at South African players have no affiliate programme we can reach. We review them anyway — but we have nothing to link, so the call to action on those pages opens Hollywoodbets instead.
That is a commercial choice and we are not going to dress it up as a public service. What we will not do is disguise it: the button says "Play at Hollywoodbets instead", the note beside it states in bold that it does not open the brand being reviewed, and the review itself says we earn nothing from that operator. The industry norm is to make the same substitution silently. The substitution is not the problem — the silence is.
Questions about our method
Can a casino pay for a better score?
No. The overall score is computed in code from the five pillar scores and the weights on this page. There is no editorial override and no field a commercial arrangement could touch. You can verify this yourself: every pillar score is printed on every review page, and the arithmetic is on this page.
Do you accept money from these casinos?
Yes, and we say so on every page that carries a link. When you open an account through a link marked as a partner link, the operator may pay us a commission. That is how the site is funded. What commission does not do is change the order of the list — see the question above.
Why do some casinos have no verified offer?
Because we could not load the figure ourselves. Some operators geo-block our testing environment, some serve promotions dynamically, and one resolves to an international promotions page rather than a South African offer. In every one of those cases we print no figure and explain why on the review page. We do not copy numbers from other comparison sites.
How often do you re-check?
Welcome offers change frequently. Every verified figure on this site carries the date it was checked, so you can see how fresh it is rather than taking "updated daily" on trust. If a figure looks stale when you arrive, treat the operator's own promotions page as authoritative.
Why is there no five-star rating?
Because a five-star scale compresses everything into the same 4.1-to-4.8 band that makes every casino look identical. A ten-point score built from five visible components tells you where a site is strong and where it is weak, which is the actual question.
