Bookies Not On Gamstop is a research-led comparison site for UK adults who want to understand betting bonuses not on GamStop before they sign up anywhere. This page explains who we are, how the rankings on continuitycentral.com are produced, where our money comes from, and the limits of what any review site can tell you about an overseas-licensed operator.

Why this site exists

GamStop is the free self-exclusion scheme that every operator licensed by the Great Britain Gambling Commission must integrate with. Register for it and you are blocked from all GB-licensed gambling sites for your chosen exclusion period — six months, one year or five years — and the block cannot be lifted early.

Casinos and bookmakers outside that scheme hold overseas licences instead, commonly from Curaçao or a similar jurisdiction, and are not connected to GamStop. They advertise larger welcome offers than British readers are used to, and those offers come with conditions that are easy to misread: high percentage matches, wagering requirements attached to both the cash and the spins, caps on what a bonus can ever pay out.

Our job is to set out those conditions plainly. We are a publisher, not an operator and not a regulator. We do not hold player funds, process payments or settle bets, and we cannot intervene in a dispute between you and a casino.

How we make money

We earn commission when a reader opens an account through some of the links on this site. That is how the site is funded and we would rather say it here than bury it.

Commercial relationships do not buy position. An operator cannot pay to be ranked higher, to have a limitation removed from its write-up, or to be described in terms its own published rules do not support. Some brands we cover pay us nothing. Where an offer looks worse than its headline percentage suggests, we say so in the same paragraph as the headline.

How we research and rate bonuses

We have not deposited, wagered or withdrawn at these sites. There is no testing claim anywhere on continuitycentral.com. What we do is read and compare published material — terms and conditions pages, bonus rules, banking pages, licensing statements and operator support channels — and record what we can verify. Findings are dated, because terms change without notice.

The factors that drive an editorial rating for a betting or casino bonus:

• Wagering requirement — the multiple you must stake before a bonus converts, and whether it applies to the bonus alone or to deposit plus bonus. A 40x requirement on deposit plus bonus is roughly double the work of 40x on the bonus alone.
• Game contribution — slots usually count 100%, roulette and blackjack often 10% or less, live dealer tables sometimes nothing at all.
• Maximum bonus bet — a per-spin or per-stake cap, frequently a few pounds, that voids winnings if you breach it.
• Expiry — how many days you have to clear the wagering, and how quickly free spins lapse.
• Cashout limits — the ceiling on what a bonus or free-spin win can ever pay out, which on no-deposit offers is often very low.
• Minimum deposit and qualifying odds — the entry cost, and for sports free bets the minimum decimal odds, commonly around 1.50 to 2.00.
• Banking and currency — whether GBP accounts exist, which methods are available to British customers, and what conversion costs apply if the account is held in euros.
• Withdrawal and verification practice — stated processing times, withdrawal limits, and how KYC and source-of-funds checks are described.

Ratings are our editorial opinion on that evidence. They are not customer-review scores, they are not a safety guarantee, and no site is ever completely safe to use.

Three of the offers we cover, and what to read twice

Our full comparison lives on the non GamStop casino rankings. The three below show the kind of reading each listing gets.

RagnaBet — the largest headline figure in our list

RagnaBet sits top of our table at 10.0, largely because its 420% up to £15,000 plus 440 free spins package is quoted in pounds, which matters for British readers who would otherwise pay conversion costs on every deposit and withdrawal. A sterling account removes one layer of unpredictable cost.

The limitation is the size itself. A £15,000 ceiling is reachable only by depositing in the thousands, and a 420% match means the bonus portion dominates the balance — so the wagering total is large in absolute terms, and the maximum bonus bet rule will apply to every spin of it. Treat the headline as the top of a tiered structure, not as what a typical £20 deposit produces, and check the per-tier terms before funding.

Kikibet — a sterling-quoted alternative with spins attached

Rated 9.9, Kikibet advertises 350% up to 5,555 £ and 300 free spins. It earns its place for the same reason as RagnaBet — a GBP-denominated offer — but with a lower multiplier, which in practice usually means a smaller bonus balance to clear relative to your deposit. Readers who dislike long wagering grinds often find a moderate match easier to finish than an extreme one.

The drawback is that free-spin packages of this size are rarely released in one go. Expect daily or staged releases, a fixed and usually low spin value, and spin winnings credited as bonus funds with their own wagering and cashout cap. Verify the release schedule before you count the 300 spins as available on day one.

Betmica — the highest percentage, with the tightest reading required

Betmica, at 9.8, advertises a welcome offer of 570% up to £5,700 plus 270 free spins. We include it because the percentage is unusually high even among non GamStop brands and because the cash ceiling is stated in sterling. For a reader who wants maximum bonus balance from a modest deposit, this is the shape of offer that does it.

The flip side is arithmetic: the higher the match, the more of your balance is restricted money, and the more the maximum bet rule, game contribution weighting and expiry window govern how you can play. A 570% match on a £50 deposit creates a bonus far larger than the cash, and the wagering attached to it will not clear in an evening. If you prefer a short, simple offer, this is not it.

All offers are new-customer promotions subject to the operator's own terms, including minimum deposit, wagering, maximum bonus bet, expiry and cashout limits. Euro-denominated offers mean conversion on deposit and withdrawal for anyone banking in sterling. Figures were checked on 4 November 2026 and can change at any time — the operator's terms page is the authority, not ours.

The money side we always look at

A bonus is only as good as the banking behind it. When we review an operator we record what it publishes about:

• Minimum deposit — the floor to qualify, often higher for a bonus than for a plain deposit.
• Debit cards — Visa and Mastercard are the usual route for UK players; credit cards are prohibited for GB-licensed gambling and many overseas sites decline them too. Your bank may also block gambling transactions outright.
• Bank transfers — slower in both directions, sometimes the only option for larger withdrawals, and occasionally carrying an intermediary fee.
• E-wallets and prepaid — availability varies by brand and by country, and PayPal in particular is rarely offered outside GB-licensed sites. Never assume a logo on a homepage means the method works for a UK-registered account; check the cashier after registration.
• Cryptocurrency — accepted by some non GamStop brands, usually fast, but the value of your balance moves with the market and consumer protection is thinner.
• Fees and conversion — operators may pass on processing fees, and a euro account will cost you a conversion spread each way.
• Withdrawal times and limits — advertised processing windows are the operator's claim, not a measured result, and daily, weekly or monthly caps can stretch a large win over weeks.
• KYC and source of funds — expect ID, proof of address and, on larger sums, evidence of where the money came from. Verifying early is the single most effective way to avoid a payout delay.

Where a withdrawal dispute arises, your route is the operator's complaints procedure first, then whatever alternative dispute resolution its licence provides. That is generally weaker than the recourse available on a Gambling Commission licence, which is part of the trade-off.

What these sites actually offer

Beyond the welcome package, the catalogues follow a familiar shape: slots from third-party software providers, with RTP and volatility figures published by the studio rather than the casino; progressive jackpot titles pooled across operators; table games including blackjack, roulette and baccarat; and live dealer rooms streamed with human croupiers. Mobile play is browser-based at most brands. We describe the categories an operator lists; we do not count titles or name games we cannot verify.

Most of these brands run a sportsbook alongside the casino, and that is where betting bonuses not on GamStop differ most from casino ones. A sportsbook offer is usually a free bet or matched bet with a minimum qualifying price in decimal odds, covering pre-match and in-play markets, accumulators, bet builders, cash-out and increasingly esports. Casino and sportsbook often share a wallet, which sounds convenient but means a casino bonus's wagering rules may restrict what you can do with the whole balance. Read which product a promotion belongs to before you move money between them.

Legality, eligibility and what you take on

It is not a criminal offence for an adult in Great Britain to bet with an overseas-licensed site. The obligation sits on the operator: advertising to and transacting with British customers without a Gambling Commission licence is an issue for the operator, not a prosecution risk for you. But accepting British customers is not the same as being authorised to serve them, and the difference matters. On a non GamStop site you are outside UKGC consumer protections, outside the UK's complaints escalation route, and outside GamStop itself.

You must be 18 or over. Every operator we list is required to verify age and identity, and accounts opened with false details are usually voided along with any winnings. Regulatory scope also differs across the UK — the Gambling Commission licenses operators in Great Britain, while Northern Ireland has its own separate gambling legislation.

If you registered with GamStop, the exclusion exists because you asked for it. Using a site outside the scheme undoes that protection, and no bonus is worth that. Free, confidential help is available from the National Gambling Helpline on 0808 8020 133, open 24 hours, and from GamCare. Blocking software such as Gamban or Gamblock, and bank-level gambling blocks, work independently of any operator. Our responsible gambling guidance sets out deposit limits, loss limits and self-exclusion options in more detail.

Corrections, questions and how to use the rankings

Pick the offer whose conditions you would actually complete, not the biggest number. If you deposit modestly, a lower match with lighter wagering beats a headline in the thousands. If you bank in sterling, favour the GBP-quoted offers and avoid paying conversion twice. If you want sports rather than slots, check the free-bet terms and minimum odds rather than the casino package.

Terms move, brands change hands, and ownership and licensing details are not always clearly published — where we cannot confirm something, we say it is unconfirmed rather than filling the gap. If you spot a figure on continuitycentral.com that no longer matches an operator's published terms, tell us through our contact page and we will recheck and date the correction. The terms of use explain the basis on which this information is provided.
