About the site

A comparison site, not a casino, and open about the difference.

Spin Prospector reviews and compares online casinos licensed to operate in Great Britain. We do not run games, hold player accounts, take stakes, pay out winnings or take any part in play. The site earns money when a reader opens an account through one of our links, and everything below is an attempt to be straight about what that does and does not affect.

Why the angle is game studios

Comparison sites almost all sort by welcome offer, which is convenient for everyone except the reader. Offers expire, get restructured and vary by region; the supplier list behind a lobby changes far more slowly and shapes every session you will ever have on that site.

So the grades here weight studio coverage most heavily. A casino carrying Nolimit City, Push Gaming and Relax Gaming alongside the NetEnt and Play'n GO staples is offering a genuinely wider range of mechanics and volatility than one running four hundred titles from two suppliers, and no bonus closes that gap.

The full method sits on the homepage, in the order we apply it. Eight criteria, the same on every operator, with a letter grade summarising the lot.

Every operator is worked through the same eight-line checklist before anything gets written about it.

Lobbies are checked on a phone as well as a desktop, because that is where most of this is actually played.

How the money works

When a reader follows one of our tracked links and opens an account, the operator pays us a commission. It costs the reader nothing and does not change the offer they land on. That arrangement funds the writing, the hosting and the time spent re-checking lobbies, and it is the standard model across this whole corner of the internet.

The obvious risk is that commission quietly buys position. Two rules keep that from happening here. Card order and grades are settled from the criteria before any commercial consideration is applied, and we list operators regardless of whether an arrangement exists — the ones with no arrangement are graded the same way as the rest.

Nothing on this site is a paid placement, and no operator gets to read a write-up before it goes live. Full detail sits on the affiliate disclosure page.

What we won't publish

No invented user reviews, no star ratings attributed to readers who do not exist, and no counts of “happy players” that nobody could verify. If we have not checked something ourselves, it does not go on the page.

No specific bonus figures either. Promotions change faster than we can re-check five sites, and a stale number presented as current is worse than no number. We record the type of offer and send you to the operator for the terms.

And nothing framing gambling as income, a strategy or a solution to anything. It is a form of entertainment with a cost attached, the odds favour the house by design, and any page that implies otherwise is selling something.

Where our judgement runs out

We can tell you which studios are in a lobby, how the filters behave and whether the app is a real product or an afterthought. We cannot tell you how a specific account will be handled, how a bonus dispute will be resolved, or whether a site will suit you personally. Those depend on circumstances we can't see from the outside — which is why the licence check, the complaints route and the self-exclusion tools get as much space on this site as the comparison itself.

Three commitments

The rules we hold ourselves to.

Short enough to remember and specific enough to be broken, which is the point of writing them down.

Grades before commerce

Criteria are applied and grades fixed before the commercial arrangement is looked at. An operator paying more does not move up, and an operator paying nothing does not get left off.

Checked, not assumed

Licence status comes from the public register, lobby contents from the lobby. Where we can't verify something — a smaller operator's supplier list, for instance — we say so rather than filling the gap.

Corrections get made

Send us something we've got wrong and it gets fixed, with the page date updated. That includes operators writing in about their own entries, provided they can point at the evidence.

Spin Prospector is an independent comparison site funded by affiliate commission. We are not a gambling operator, not part of the Gambling Commission, and not owned by or affiliated with any brand listed. We do not run games, hold accounts, handle any part of play, or deal with operator complaints — those go to the operator and, if unresolved, to its approved ADR provider.
