Eight bookmakers licensed in Curacao accept UK sign-ups and run a sportsbook beside a casino. Four of them get a full write-up below. The list sets all eight side by side on licence, entry deposit, payout window and one sportsbook fact.
Which of these counts among the best betting sites not on GamStop depends on the sports you back and the method you pay with. No score settles it.
All four below are non GamStop bookmakers licensed in Curacao. Registration goes through with an active GamStop exclusion, and none of them answers to a UK complaints process. The order is an editorial selection, not a ranking. Among bookmakers not on GamStop, these four run from a low-deposit entry point to the largest game library in the group.

Esports betting and virtual sports are the two additions MyStake's card puts beside a standard sportsbook. Mini-games fill the gaps between fixtures. The operator is Santeda International B.V., trading under Curacao licence OGL/2024/250/0115.
The cashier opens at £20. Deposits go through Visa, Mastercard, Skrill, Neteller and MiFinity. There is also a long crypto list that includes Bitcoin, Tether, USDC and Dogecoin. Payouts go back by card, Skrill, Neteller, Bitcoin, Ethereum or bank transfer, with 1-3 business days listed.
No voucher option appears, so Paysafecard users need another route in. Support runs as 24/7 live chat. A crypto cashback programme rewards play funded in coin rather than sterling.
Best for: punters who mix football with esports and virtuals and want support at any hour.

BassWin is the only bookmaker of these four that takes Apple Pay at the cashier. Its card also flags credit card deposits. These sit alongside Visa, Mastercard, Skrill, Neteller, Bitcoin, Ethereum and Tether.
Entry is low, with a minimum deposit of £10. Withdrawals are listed at 36 hours, the shortest window quoted on any card in this pool. The card notes fast crypto withdrawals on top, and cash returns by card, e-wallet, Bitcoin, Ethereum or bank transfer.
The sportsbook lists 55+ sports.
Founded in 2024, BassWin is the youngest brand here. Cerberlot N.V. operates it under a Curacao licence. The casino side is lighter, with 1,500 slots, and leans on daily slot tournaments and lottery rewards instead. A short history means fewer settled disputes to judge it by.
Best for: iPhone users betting small stakes who want wallet funding and a short payout window.

Rolletto's deposit page reads differently from the rest of the group. It takes Visa, Mastercard, Interac, AstroPay and JetonBank, plus crypto including Monero and XRP. Skrill and Neteller appear only on the withdrawal side, next to cards, Bitcoin, Monero and bank transfer. If you plan to cash out to an e-wallet, confirm that route works before you fund by card.
A £10 minimum deposit opens the account. Withdrawals are listed at 1-3 business days, and the card separately advertises instant Bitcoin payouts.
On the sports side, Rolletto bundles esports and virtual sports with its main markets and promotes Grand Betting on major leagues. Santeda International B.V. runs it under Curacao licence OGL/2024/1798/1048. The casino lobby holds 6,000 games, with slot races for anyone who switches over between matches.
Best for: crypto punters with a modest bankroll who bet esports as well as football.

With 7,000 games, Cosmobet holds the largest library of these four. The sportsbook also reaches further than most. Its card lists snooker, darts, cricket, Gaelic football, Formula 1 and golf, plus esports titles such as Counter-Strike, Dota 2 and Valorant.
Accumulator boosts are the headline sports feature. A boost typically grows with the number of legs, and so does the chance that one leg sinks the slip.
The licence is Curacao OGL/2024/1798/1048, held by Santeda International B.V. Deposits start at £20. Funding runs through cards, Skrill, Neteller, Paysafecard, AstroPay or crypto including Tron and Dogecoin. Withdrawals are listed at 1-3 business days, and the card notes instant crypto payouts. A crypto-first cashback scheme and a separate crypto welcome offer show where the operator points its rewards.
Best for: accumulator punters who also play the casino between fixtures.
GamStop binds only operators licensed for Great Britain. Every gap between these bookmakers and a UK bookie follows from that one fact.
Every brand in this pool holds a Curacao licence and accepts UK registrations. The GamStop register is shared with UK-licensed operators, so non GamStop betting sites never receive the list. An active exclusion therefore does not stop an account being opened.
The licence sets the operator's own rules and names a regulator above it. It removes several layers a UK punter is used to. There are no affordability checks, no UK dispute route and no link to GamStop. Bonus terms are whatever the operator writes.
A non GamStop sportsbook is accessible to UK players, and that is the full extent of the claim. The protections it lacks become yours to replace.
The licence number normally sits in the site footer, often as a clickable seal. Copy the number and search the Curacao regulator's public register yourself rather than trusting the seal's link. The entry should match the operator name in the terms, such as Santeda International B.V. for several brands here. A mismatch, or no number at all, is a reason to stop before depositing.
Most of the gap between a UK-licensed bookie and UK betting sites not on GamStop comes down to who enforces the rules. The table sets the main areas side by side.
| Area | UK-licensed bookmaker | Bookmakers in this pool |
|---|---|---|
| Self-exclusion | GamStop across every UK-licensed site | Each site's own tools, one site at a time |
| Affordability and deposit checks | Spending and source-of-funds checks | No UK affordability checks; £10 minimum deposit at Rolletto and BassWin, £20 at the other six |
| Free bet and bonus rules | Terms shaped by UK rules | Terms set by the operator |
| KYC timing | Identity checked at or soon after sign-up | Typically at the first withdrawal |
| Dispute route | UK complaints route | Operator first, then the Curacao licensing authority |
| Payment methods | PayPal, Trustly, open banking | Cards, e-wallets, vouchers, crypto at every brand |
| Apps | Store apps | Browser play on a mobile-optimised site |
The middle column lists what a UK sign-up gives up: a single exclusion covering every site, checks that slow a heavy spender, and an outside body to rule on disputes. The right column adds payment choice and looser bonus terms. The checking a UK regulator would do falls to you, covering the licence, the terms, the limits and the payout record.
Football, racing and the main televised sports appear across betting sites not on GamStop, but depth varies by operator. Some cards give a sports count, while others name a single feature.
Football is the anchor of non GamStop sports betting. Markets typically cover the Premier League, the EFL, the major European leagues and international fixtures. Match odds and goal totals form the core. Accumulators are the standard slip, and Cosmobet adds accumulator boosts on top.
For in-play, Velobet's card pairs live betting with live streams, so you can watch the match the stake rides on. Freshbet counts 90,000+ live sports events a year. Before you settle on football betting not on GamStop at any one site, check how quickly it settles markets and whether a slip is accepted at the price shown.
Racing coverage is thinner than football across the pool. DonBet's card lists horse racing and greyhounds among its 40+ sports, and most other cards do not name racing at all. Where racing appears, the standard menu is UK and Irish meetings, win and each-way bets, and ante-post markets.
On non GamStop horse racing betting sites, each-way terms vary by operator and by race. That covers the number of places paid and the fraction of the odds. Check both on the bet slip, and read the non-runner rules before backing ante-post.
BassWin lists 55+ sports, the broadest count quoted in the pool. Cosmobet's card names snooker, darts and tennis alongside niche markets. Rolletto and MyStake both add esports and virtual sports, which fill the calendar when no live fixture is on. Virtual results come from a random generator, so form study counts for nothing there.
Every card in this pool lists a mobile-optimised site and no dedicated app. Betting apps not on GamStop are rare because app store gambling policies typically tie approval to a licence in the player's own market, and a Curacao operator has none for the UK. In practice the site runs in the phone's browser:
That convenience comes at a cost in two places. Push notifications for settlements are generally missing. In-play betting also depends on the browser refreshing, which can lag behind a native app when prices move fast.
Five steps take an account from sign-up to a first settled slip.
A limit set while calm holds better than one set after a losing run.
Sportsbook promotions at non GamStop bookies follow familiar shapes, but the operator writes every term. Read these points before claiming:
Wagering on a welcome match usually decides whether a bonus is worth taking, because a multiplier on deposit plus bonus can lock a balance for weeks.
Payment menus at bookies not on GamStop fall into five groups:
Rolletto and BassWin take deposits from £10, and the other six ask for £20. The minimum withdrawal is £20 everywhere. The standard listed window is 1-3 business days. BassWin's card quotes 36 hours instead.
PayPal, Trustly and pay by phone bill appear on no card in the pool. These processors typically restrict gambling payments to operators licensed in the customer's own market, which rules out a Curacao bookmaker taking UK players.
Crypto clears faster because no card network or receiving bank sits in the chain once the operator approves the payout. Rolletto advertises instant Bitcoin payouts. Cosmobet's card notes instant crypto payouts too. The speed has a price, though: network fees come off the amount, and the coin's value can move before you convert it back to pounds.
Most of these sites ask for three documents. These are photo ID, a recent proof of address, and proof of the payment method, such as a card photo with the middle digits covered or an e-wallet screenshot. The request typically arrives at the first withdrawal, though some operators ask at sign-up or once deposits pass a threshold the operator sets.
Daily, weekly and monthly withdrawal caps sit in the terms rather than the cashier, and each figure varies by operator. Read them before a big win, because a cap can split one payout across several weeks.
The first payout is slower because verification and the withdrawal run together. Listed windows on betting sites not on GamStop assume an account that has already cleared. The 36 hours BassWin quotes is one example.
When a check stalls, ask live chat which document is missing or unreadable. Resubmit a clear colour scan and keep every message. Avoid reversing the withdrawal to bet again, since that returns the funds to play and typically restarts the queue. If the operator stops answering, the complaint goes to the authority named on the licence.
None of the betting sites not on GamStop here carries a UK guarantee, so the checks fall to you. Six points, grouped in three pairs, cover the essentials.
The footer should show a licence number that matches an entry on the regulator's public register, under the same operator name as the terms. The withdrawal terms should publish the minimum, the processing window and the daily, weekly and monthly limits in one place.
Bonus rules belong on a single page that states wagering, maximum bet and expiry without sending you elsewhere. Known suppliers matter too. Names such as Evolution or Pragmatic Play in the casino lobby, and a named odds feed on the sportsbook, show the site runs on established supply.
Send a question to live chat or email before depositing, and judge the reply on substance as well as speed. Then open the account settings. Deposit limits, time-outs and self-exclusion should be available there without asking support to switch them on.
Account tools still work at every brand here: deposit limits, loss limits, session limits, time-outs and self-exclusion. Each one binds a single site, so a limit at one bookmaker means nothing at the next. You need to set them at every account you open.
Covering sites outside the scheme takes tools that sit on your device or with your bank:
GamCare and the National Gambling Helpline offer free, confidential support.
Anyone who joined GamStop for a reason should not be signing up to betting sites not on GamStop at all.
Every brand in the pool runs a casino lobby beside its sportsbook on one wallet, so a balance moves between a slip and a slot with no transfer. The lobby splits three ways:
The shared wallet is convenient, but it removes a natural stop. Winnings from a bet can drift into the casino as easily as the reverse.
Four brands in the pool date from 2023 or later:
A young sportsbook typically trades bigger promotions for a thinner record, with fewer settled withdrawals to judge and fewer complaints on file. Cosmobet and Velobet partly offset that, since Santeda International B.V. also runs older brands in this pool. Before funding one of the new betting sites not on GamStop, confirm the operator on the licence register and push a small withdrawal through early.
An editorial desk covering offshore betting maintains this page and reviews it regularly. Brand details are rechecked whenever an operator changes its terms. The figures rest on three sources:
Where an operator's terms and a register entry disagree, the register entry takes precedence.
