About The Best Slots Sites

The Best Slots Sites is operated by Jumpman Gaming Limited, a company licensed by the UK Gambling Commission (licence number 039175-R-319452-024) continuously since 1 November 2014. Jumpman Gaming Limited also owns and operates some of the casino brands listed on this site, alongside partner brands it does not own. We rank operators using a combination of bonus value, terms fairness, payment options, and licensing, and we receive advertising fees from the operators we list.

All operators listed on this site are licensed by the UK Gambling Commission. 18+ only. Please gamble responsibly.

How we review and rank

Every operator and slot listed on The Best Slots Sitesis assessed against the same set of criteria before it's added or ranked: UK Gambling Commission licence status, the fairness and clarity of bonus terms, UK payment reliability, game selection and provider quality, and player-facing support tools. Star ratings and rankings reflect this combined assessment, not just bonus size, and we only list operators holding a current UK Gambling Commission licence. See How We Rate for the full methodology, including how bonuses and providers are assessed and what disqualifies an operator entirely.

How we make money

The Best Slots Sitesis free to use, and we make money in two ways. First, we earn advertising fees when a visitor signs up with an operator through a link on this site — every "Get Bonus" and "Claim Offer" button is an advertising link, which is why this site is marked as an ad.

Second, Jumpman Gaming Limited — the company that operates this site — also owns and operates some of the casino brands listed here. When a player joins and plays at one of those brands, we profit as the operator, not just as the advertiser. Other listed brands are partner brands we do not own, where we earn advertising fees only.

What this does not change: we do not accept payment for a higher ranking or star rating, and brands we own are scored against the same criteria as brands we don't — see How We Rate for the methodology. This commercial model is flagged in the banner on every page and set out in full in our Terms of Service. Bonus offers and terms shown on this site are supplied by operators and can change; the operator's own terms and conditions always take precedence over the summary shown here.

How we score slots

Each slot listed on The Best Slots Sitescarries a score out of 10, built from its published RTP, volatility rating, maximum win multiplier, bonus feature depth, and the track record of its software provider — sourced from the provider's own published game data wherever available, cited at the bottom of the review, rather than third-party aggregator figures. See How We Rate for the full breakdown.
