How we rate casinos and slots

• We only publish what we can observe: public Kick channels, providers' game pages, casino websites and regulator registers.
• We show no simulated or estimated live numbers. If we have no observation, the figure is zero or missing.
• Missing data is shown as missing. We don't guess a licence, an RTP or an operator to fill a gap.
• The same rules apply to every casino and slot, whether or not we have a commercial relationship with it.

Popularity is a score from 0 to 100, recalculated every 15 minutes. It combines two observed signals:

• 70% — how many different Kick streamers we have seen playing the slot in the last 30 days.
• 30% — how many casinos in our catalogue carry the slot.

Both signals are on a logarithmic scale relative to the most-streamed and most-carried slot in the catalogue. That way a slot played by 200 streamers doesn't completely drown out one played by 20, and the top slot on each signal sets the upper end of the scale.

Players online is the number of viewers watching live Kick streams of that slot right now. It counts only streams where we identified the slot in the last 90 minutes. It is not a count of people spinning the slot at casinos, which no outside site can see.

The trending slots list is sorted by this score.

Where available, a slot's RTP (return to player) and volatility come from the provider's own published game page. Slots whose RTP we read from the provider are marked as provider-verified. The full list, with the date each figure was checked, is free to download on our open data page.

Providers often release one game in several RTP configurations, and each casino chooses which one to run. The figure we show is the one on the provider's page; a given casino may run a lower version. Always check the game's info screen at the casino before you play.

We read licences from the casino's own website (usually the footer, where licensed operators must show their licence) and from regulator registers. Where a casino appears in the UK Gambling Commission or Malta Gaming Authority public register, we record that match and mark the licence as checked against the register.

If we can't find a licence, the casino page says so. We never infer a licence from a casino's marketing, its country or its sister sites.

The casino rating is computed by our own rule-based formula from facts we have on record. It is not an editor's opinion, and it is not taken from another site. It is recalculated for the whole catalogue once a day, so a change to a licence or operator record changes the score the next day. The same formula applies to every casino.

For online casinos the signals are:

• Licence tier — the strongest regulator on record. The UK Gambling Commission and the Malta Gaming Authority score highest, then other national regulators (for example Portugal's SRIJ, Sweden's Spelinspektionen, Ontario's AGCO / iGaming Ontario, Germany's GGL, Italy's ADM). Curaçao earns a small credit. Having no licence on record scores nothing.
• More than one licence — a small extra credit.
• Licences checked against a regulator register, including a match in the UKGC or MGA public register.
• Verified website domains for the casino.
• A publicly named operating company.
• A substantive description of the casino on record.

Land-based venues are scored on a different set of signals (physical address, map location, named operator, description and years in operation), because domains and online licences mean little for a physical casino.

Scores are kept between 3.0 and 4.5 and rounded to one decimal. So that casinos with identical signals don't all share one score, each gets a fixed offset of at most ±0.15, derived from its page address. The offset never changes, has nothing to do with the casino itself, and can't be bought. Treat differences of 0.1 to 0.3 between two casinos as a tie.

What the rating does not measure: game quality, bonus value, payout speed or customer service. We have no independent data on those, so they are not in the score. Read player reviews on each casino page for that kind of experience.

Everything on our streamer pages comes from public Kick channels. We check live slot streams every few minutes and record who is live, how many viewers they have, and which casino and slot they are playing.

We identify the slot from the stream title and from a recent frame of the stream, then match it to a slot in our catalogue. If we can't identify the game with confidence, the streamer is shown as live without a slot, never with a guess. Over time these observations build each streamer's history of casinos and slots, which also feeds slot popularity above.

A streamer appearing on SpinScout doesn't mean they endorse us or any casino listed here.

• Only signed-in users can post casino reviews, slot comments and community posts. They are published straight away, without pre-moderation.
• Links and web addresses are stripped from posts to keep out spam.
• Each account has a daily limit on reviews, comments and posts.
• Any signed-in user can report a post. Our admins review reports and remove abuse, spam and fake reviews.
• We don't show reviews imported from other sites. Every review on SpinScout was written here by a registered user.

Casino operators can't edit or remove reviews of their casino. Reviews are not paid for and don't change the computed casino rating.

SpinScout is funded by affiliate commissions: when you sign up at a casino through some of our links, the casino may pay us a referral fee. That doesn't cost you anything. It doesn't buy rankings, inclusion or reviews. The rating formula above is the same for partners and non-partners. The full disclosure is on how we make money.

If a licence, operator, RTP or rating on SpinScout looks wrong, email [email protected] with the page and what's off. We fix the underlying record, so the correction flows through to every page and score that uses it.
