How we review
How Sister Sites tests and rates casino sister sites — licensing, bonuses, payments, UX, support, and trust signals.
Sister Sites is committed to unbiased, accurate reviews. We only recommend casinos that pass a structured evaluation — and we explain what we checked so you can judge the verdict for yourself.
Our evaluation process
Seven areas we always cover
1. Licence & reputation
Safety first: licensing signals, operator history, and player-protection tools.
2. Sign-up & KYC
Registration clarity, verification friction, and account readiness.
3. Real-world testing
Where possible we test deposits, play flow, and withdrawals ourselves.
4. Value assessment
Bonuses, wagering, payment options, and fees that affect real players.
5. User experience
Games, mobile use, navigation speed, and overall stability.
6. Support & safer play
Help channels, response quality, and responsible-gambling tools.
7. Sister-site mapping
How we prove brands share an operator — ownership, licences, platforms, and portfolio patterns.
1. Licence and industry reputation
Safety is the foundation of every review. We look for clear licensing information, operator history, and whether safer-gambling tools are easy to find. A licence alone is not enough — we also weigh reputation signals such as public complaints, regulatory actions where known, and consistency across sister brands.
2. Sign-up and verification
We assess how easy it is to create an account, how clearly the site explains identity checks, and whether verification feels proportionate. Friction that protects players is good; unnecessary obstacles or unclear document requests are called out in the review.
3. Real-world testing
Where access allows, we go beyond marketing pages: sign up, explore the cashier, place test activity, and note withdrawal behaviour. FAQs and support scripts rarely tell the full story — hands-on checks help us separate polished landing pages from day-to-day usability.
4. Value assessment
Welcome offers
We read the full bonus terms — wagering, max cashout, game weighting, and expiry — not just the headline amount.
Ongoing value
Reload deals, cashback, VIP perks, and payment fees matter as much as the first deposit bonus.
Cashier quality
Useful methods, realistic limits, and transparent processing times score higher than a long logo wall.
Fine print honesty
If terms bury important limits, we say so. Clear, fair offers score better than flashy ones with traps.
5. User experience
Focus | What we test |
|---|---|
Lobby & games | Variety, load stability, search/filter quality, and provider mix. |
Mobile | App or mobile browser usability — where most players spend their time. |
Navigation | Can you find banking, support, and game categories without friction? |
Performance | Slow menus, broken buttons, and unstable sessions cost marks. |
6. Customer support and safer gambling
We check which channels exist (live chat, email, help centre), how useful answers are, and whether responsible-gambling tools — deposit limits, time-outs, self-exclusion — are visible and usable. Weak support often signals wider quality issues.
7. How we find casino sister sites
This is the core of Sister Sites. Casinos rarely advertise a full sister network, so we research public signals and group brands under the operator (company) we believe is the licensed or controlling entity. Brands that sit under the same operator in our directory are treated as sister sites of each other.
Operator first
Every casino review hangs under an operator page. Sister lists are built from that shared parent — not from a marketing claim on a landing page.
Ownership & licence
We read terms, footers, licence registers, and company disclosures to match brands to the same owner or licence holder where the evidence supports it.
Platform & product patterns
Shared software stacks, near-identical lobbies, mirrored bonus structures, and repeated payment setups are strong clues that brands belong together.
Portfolio tracking
When an operator launches or rebrands a casino, we place it in the right network and keep older sisters linked so the map stays useful over time.
Signals we check before calling brands sisters
Signal | Why it matters |
|---|---|
Named operator / company | The clearest link: the same legal entity named across terms, licence pages, or corporate sites. |
Licence details | Matching licence numbers or the same licencee across brands supports grouping — we still verify, because white-labels can look similar. |
Shared platform or skin | Near-clone lobbies, identical help centres, or the same cashier layout often mean one operator running multiple brand skins. |
Bonus and T&C DNA | Copy-paste welcome offers, identical wagering wording, or the same promo engine across domains is a practical sister clue. |
Payment and support fingerprints | The same method mix, limits, and support scripts across brands usually point to one backend operation. |
Launch and rebrand history | New domains that inherit an existing operator’s stack are added as sisters; closed or renamed brands are updated so the network stays accurate. |
How sister mapping shows up in a review
Operator profile
We publish a company page that lists the casinos we have confirmed under that operator.
On-page sister links
Casino reviews link to sibling brands in the same network so you can compare alternatives quickly.
Fact tables
Owner and licence fields summarise what we found; the sister group itself is the operator relationship behind those facts.
When things change
Ownership and licensing move. When evidence shifts, we re-parent casinos to the correct operator so sister lists and URLs stay aligned.
We do not treat a single lookalike logo or rumour as proof. Sister status is an editorial judgment based on multiple signals, checked against current operator materials before we publish or update a network map.
We also weigh public player feedback where it is credible, while recognising that review sites can be noisy. Writing standards for how we present all of this are in our Editorial guidelines.
What our verdict means
Not a guarantee
Casinos change bonuses, ownership, and terms. Always re-check key details on the operator site before you deposit.
Independent judgment
Affiliate commissions never buy a positive score. See Affiliate disclosure for the full explanation.
