What OddsBully covers
OddsBully publishes three types of content:
- Slot reviews. Every title we cover gets an RTP figure, a volatility rating, a max win multiple, and a summary of the mechanics. This is the core of the site.
- Casino and operator assessments. We assess online casinos and sportsbooks across five criteria (detailed below). We cover operators licensed in our active markets.
- Country and market guides. Regulatory explainers, payment-method pages, and responsible-gambling resources for the seven jurisdictions we actively cover: Ireland, UK, Canada, Australia, South Africa, Nigeria, and Kenya.
We do not cover operators that are unlicensed in the jurisdictions we serve. We do not cover markets we have not researched.
Slot reviews: how RTP data is sourced
RTP is the most important number in a slot review and the most often misrepresented one. Our sourcing hierarchy is:
- Provider technical sheet or official game page. If the developer publishes a verified RTP, that figure takes precedence over everything else.
- In-game information panel. The paytable or "?" screen in the game itself. This is the figure the regulator holds the operator to in licensed markets.
- Operator-stated figure, flagged. If neither of the above is available, we use what operators publish and label it "operator-stated, not independently verified."
Volatility ratings (low / medium / high / very high) are based on the game's mechanic structure — hit frequency, feature frequency, and the shape of the win distribution — cross-referenced with provider descriptions where published. We do not derive volatility from a short play session alone.
Max win multiples come from the provider paytable or the game's help screen. We do not estimate or extrapolate max win figures.
Casino and operator assessments
We assess every operator we cover across five criteria:
- Security and licensing. Licence validity verified against the issuing regulator's live public register. Company registration, known enforcement history, and SSL posture.
- Payments. Supported rails in the operator's licensed markets, deposit and withdrawal speeds, fees, and KYC friction. Where we have conducted a real-account test, withdrawal times are measured end-to-end and noted as tested. Where we have not, we use the operator's stated figure and note it as such.
- Game catalogue (or odds and markets for sportsbooks). For casinos: RTP sample across the catalogue, provider mix, live-dealer availability, game count. For sportsbooks: overround on primary leagues, market depth, in-play coverage.
- User experience. Registration friction, mobile quality, account-limits accessibility, and self-exclusion discoverability.
- Customer support. Channel availability, tested response time where feasible, dispute-resolution clarity.
We do not produce a single numeric composite score. Each criterion is assessed qualitatively and described in the review. A strong bonus offering does not compensate for a weak licensing position.
Country and market guides
Our market guides cover Ireland, UK, Canada, Australia, South Africa, Nigeria, and Kenya. For each market we publish:
- A regulatory overview citing the relevant legislation and the licensing authority.
- A payment-methods guide covering the rails most used by players in that market.
- A responsible-gambling page with the national helpline and self-exclusion scheme for the jurisdiction.
- Operator shortlists (casinos or sportsbooks depending on what is legally available in the market).
Every regulatory claim cites a primary source — the regulator's public register, a statutory instrument, or a published enforcement decision. Where a primary source cannot be located, we remove or flag the claim rather than repeat it unchecked.
Australia and South Africa are sports-wagering-only markets for this site: online casino products are either prohibited or operate in a legally ambiguous environment we are not comfortable recommending. Casino content is not published for those two markets.
Who writes the content
Every page carries a named author and an updated date, visible in the byline below the page title. The author is responsible for the accuracy of the content and for cross-referencing any regulatory or technical claims against primary sources.
We do not use anonymous "editorial team" credits on pages that make factual claims about licences, RTP figures, or regulatory frameworks.
Affiliate disclosure and independence
OddsBully earns commission when a reader signs up with an operator through our tracked links. This is the standard affiliate model used across the industry. What we avoid:
- No operator pays for placement or for a minimum assessment outcome.
- No operator reviews a draft before publication.
- No operator has editorial input on our wording or our criteria.
- We do not run paid placements that are presented as independent editorial.
Our commercial agreements are structured per acquisition, not per word or per score. A negative assessment is published and stays published regardless of whether we have a commercial relationship with the operator.
How we keep content current
The updated date on each page reflects when the content was last reviewed. We update a page when:
- An operator's licence status changes (new licence, suspension, lapse).
- A regulator publishes a material enforcement decision affecting an operator we cover.
- A payment rail we cited is discontinued or its terms change materially.
- A provider changes the stated RTP of a game we have reviewed.
- A law or regulation we have cited is amended or superseded.
We monitor regulator announcement pages and provider release notes. We do not guarantee a fixed re-review schedule for every page, but we do not leave material factual errors in place once we are aware of them.
What we do not do
Some things are off the table regardless of commercial pressure:
- We do not cover operators that are unlicensed in our readers' jurisdictions.
- We do not use "risk-free", "easy money", or "guaranteed win" phrasing.
- We do not write copy aimed at under-18s, nor use imagery that skews young.
- We do not present operator-owned promotional pages as independent assessments.
- We do not publish RTP figures we cannot source to a provider or regulator document.
- We do not claim to have personally tested a withdrawal time unless we have.
If any of the above needs to change for any reason, it will be with a dated note on this page. Nothing gets changed quietly.
FAQ
- Do operators pay you for good reviews?
- No operator has a say in our ratings. We earn affiliate commission on sign-ups, but our assessment criteria are applied before any commercial conversation. A poor assessment stays poor regardless of deal size.
- Where does the RTP data come from?
- We source RTP from the official provider paytable or game information panel first. Where the provider publishes a technical sheet, we use that. Where neither is available, we note that the figure is operator-stated and unverified by us.
- Why do you show sub-scores instead of one overall number?
- A single overall score hides more than it shows. A reader who primarily cares about withdrawal speed should weight payments differently from one who cares about game catalogue depth. Sub-criteria let you do that.
- How often is content updated?
- Slot reviews are refreshed when a provider changes the stated RTP or releases an updated version of the game. Casino and market content is reviewed when we become aware of a material change — a licence update, a regulatory shift, or a payment rail change. The updated date on each page reflects when it was last reviewed.
- Who fact-checks the regulatory claims?
- The author cross-references every regulatory claim against a primary source — the relevant regulator's public register, a published statutory instrument, or an enforcement notice. Where a primary source cannot be found, we flag the claim or remove it.
