100% + 50 Free Spins Bonus
Non GamStop casinos draw UK players for narrow, practical reasons. A typical case: a player chose a long GamStop exclusion during one bad month, the term is still running, and every site that checks the register now turns the account down. In practical terms, casinos not on GamStop accept registrations from UK residents, operate under a licence issued outside the UK, and sit outside the scheme altogether. A GamStop self-exclusion therefore does not reach them. Play at every one of them is restricted to adults aged 18+.

Five sites not on GamStop follow, each described from the figures its operator publishes: entry deposit, cash-out floor, wagering multiple, library size and payment routes.

A £5 deposit is enough to open play at Slim King Casino, the lowest entry point of the 5 brands covered here. The same low floor applies to the first tier of its welcome offer (€5), with €20 required for later tiers. For a first visit to a casino not on GamStop, that keeps the amount at risk small while the cashier and support are checked.
The site launched in 2026 under Green Champions Leader S.R.L. and is built around a minimalist, mobile-first interface. Its licence entry reads Costa Rica, marked as unlicensed.
The welcome package runs to €1,500 plus 500 extra spins across 3 deposit tiers. Wagering is 35x on deposit plus bonus, and the same 35x covers spin winnings. Spins arrive in daily batches over 5 days, the bonus stays valid for 30 days, and cash-out limits apply.
Cashing out starts at £85. Crypto and e-wallet payouts are listed at up to 24 hours, cards at 1 to 3 business days. Deposits go in by Visa, Mastercard, Bitcoin, Tether, Revolut or Apple Pay; withdrawals leave by bank transfer, Bitcoin, Tether or Revolut. The library holds 2,200 games, including 2,000 slots and 100 live tables, from studios such as BGaming, Evoplay, Belatra and Gamzix.
Pros
Cons
Best for: a cautious low-stakes player who wants to test a new site with the smallest possible first deposit.

Koi Spins Casino is operated by Cerberlot N.V. together with Fortune Master Limitada and has been running since 2022 under a Curaçao eGaming licence. The theme is oriental. The same account opens a sportsbook with a cybersports section, and the site runs regular tournaments.
Its welcome offer is 450% up to €3,000, split across 3 deposits: 200% on the first, 150% on the second and 125% on the third, each capped at €1,000. Qualifying deposits step up from €40 to €100 to €200. Wagering is 35x on the bonus amount only, single bets are capped at €2 during bonus play, and the offer expires after 7 days.
Entry costs more here. The minimum deposit is £40 and the minimum withdrawal £150, the highest floor of the 5 casinos not on GamStop covered. Payment choice is also the narrowest: Visa, Mastercard, Bitcoin, Tether and bank transfer for deposits, then only bank transfer or Bitcoin for withdrawals. Bank transfers are listed at 24 to 48 hours, Bitcoin at up to 24 hours.
The game count is 3,000, with 2,600 slots and 150 live tables. Novomatic, Play'n GO, Betsoft, Endorphina and GameArt appear on the supplier list.
Pros
Cons
Best for: a mid-stakes player who wants casino and esports betting on one account and is content to cash out by bank or Bitcoin.

Wagering is where Cosmobet Casino separates from the group: 30x, the lowest multiple of the 5 brands here. It applies to deposit plus bonus on a 100% match up to £500, entered with a £20 deposit. A separate crypto welcome offer carries 35x instead. Stakes are capped at £5 while wagering, slot wagering must finish within 7 days, and free spins expire in 24 hours.
Behind the site is Santeda International B.V., trading since 2023 with a Curacao licence. Crypto-first cashback, accumulator boosts on sport and leaderboards make up the rest of the feature list.
The library ties for largest here at 7,000 games, of which 5,500 are slots and 200 are live tables. Evolution and Ezugi supply live play, alongside Pragmatic Play, Hacksaw and Nolimit City on the slot side.
Both money floors sit at £20. Deposits accept cards plus Skrill, Neteller, Paysafecard, AstroPay, Bitcoin, Ethereum, Tron, Litecoin and Dogecoin. Withdrawals run through Visa, Mastercard, Skrill, Neteller, Bitcoin, Ethereum or bank transfer. The operator advertises instant crypto payouts, yet the listed withdrawal time is 1 to 3 business days.
Pros
Cons
Best for: a slot player who takes the welcome bonus and can clear the turnover within a single week.

Goldenbet Casino has been trading since 2021, the longest record of the 5 brands here. By the standard of non GamStop sites that is a long run: Slim King and Betmica both launched in 2026. The operator is Santeda International B.V., the same company behind Cosmobet, and the licence comes from Curacao.
Payments are the widest in the group. Alongside Visa, Mastercard, Skrill, Neteller, MiFinity and AstroPay, the deposit list carries Bitcoin, Ethereum, Litecoin, USDT, XRP, DOGE, TRX, DASH and BCH. Withdrawals go back through cards, Skrill, Neteller, MiFinity, PIX, Bitcoin, Ethereum or bank transfer. Minimums are £20 each way, and payouts are listed at 1 to 3 business days.
On the game side, 7,000 titles include 5,600 slots and 200 live tables, supplied by studios such as Pragmatic Play, Evolution, NetEnt and Nolimit City. A sportsbook, 10% unlimited cashback, tournaments and a VIP programme sit alongside. Play runs through a mobile-optimised site; there is no dedicated app.
The welcome bonus is a 100% match up to £500 at 35x, above sister site Cosmobet's 30x. Stakes are capped at £5, and the bonus allows 30 days for completion.
Pros
Cons
Best for: a player who values operator track record and payment choice over the smallest wagering multiple.

Betmica Casino carries the largest headline welcome offer in the set: a package up to £5,000 (or €5,000) plus 250 free spins. A separate sports offer matches 100% up to £200. Bonus funds and spin winnings both carry 35x wagering, the window is 14 days and stakes are capped at £5. The sports side needs 10x rollover at minimum odds of 1.80.
Payout speed depends on the route. E-wallets and crypto are listed at up to 24 hours; bank transfer takes 2 to 5 business days. Visa and Mastercard accept deposits but are absent from the withdrawal list, which runs to bank transfer, Bitcoin, Tether, Skrill and Neteller. The minimum deposit is £20, the minimum withdrawal £100.
Live play is the deepest of the 5: 250 live tables inside a 4,500-game library that includes 4,000 slots. The supplier list (Pragmatic Play, NetEnt, Microgaming, Hacksaw Gaming, Relax Gaming, Play'n GO, BGaming) leans towards slots.
Betmica N.V. and Softon Ltd run the site. It launched in 2026 under an Anjouan Gaming licence and advertises high-roller limits alongside its sportsbook.
Pros
Cons
Best for: a higher-staking player who splits sessions between live tables and sports betting.
Across the 5 reviewed non GamStop casinos, the entry deposit ranges from £5 to £40 and the minimum withdrawal from £20 to £150. Those 2 floors, the wagering multiple and the fastest listed payout decide most of what an online casino not on GamStop costs in day-to-day use.
| Casino | Min deposit | Min withdrawal | Wagering | Fastest listed payout |
|---|---|---|---|---|
| Slim King | £5 | £85 | 35x deposit + bonus | Crypto / e-wallets: up to 24h |
| Koi Spins | £40 | £150 | 35x bonus | Bitcoin: up to 24h |
| Cosmobet | £20 | £20 | 30x deposit + bonus | 1 to 3 business days |
| Goldenbet | £20 | £20 | 35x | 1 to 3 business days |
| Betmica | £20 | £100 | 35x bonus | E-wallets / crypto: up to 24h |
The sharpest gap is the withdrawal floor. At Cosmobet and Goldenbet, any balance from £20 upward can leave the account. At Koi Spins, nothing below £150 can be withdrawn, so a modest win stays locked until play takes it past that line or loses it. For a player who withdraws small wins regularly, that floor matters more than any bonus figure.
The second difference is how speed pairs with those floors. The 2 sites with £20 floors list 1 to 3 business days. The 3 sites offering routes at up to 24 hours ask for £85 to £150 before releasing anything. Frequent small withdrawals trade speed for access. Rare, larger ones can use the faster routes without hitting the floor.
Account mechanics at non GamStop casinos differ at 4 points: what sign-up asks for, who sets limits, when identity is checked and how far an exclusion reaches.
Registration usually runs to a single form: email, password, name, date of birth, address and account currency. All 5 reviewed brands list GBP as an account currency, so a sterling balance is available from the first deposit. Documents are rarely requested at this stage. Some sites add a bonus selection step before the first payment.
Deposit limits and loss limits are generally optional, set by the account holder in settings or through support. At non GamStop casinos the default is often no cap at all. A limit covers the whole account, so it applies to slots not on GamStop and live tables alike. Lowering a limit typically takes effect at once; raising one often comes with a waiting period that varies by site.
Identity verification (KYC) is commonly triggered by the first withdrawal rather than by sign-up. Other triggers include large cumulative deposits, a new payment method or a mismatch between account and card details. A passport or driving licence, a recent utility bill and proof of payment ownership are the usual requests. Until they clear, the withdrawal waits on top of the listed payout time.
Most of these sites offer their own cooling-off periods and self-exclusion, applied per account through support or settings. Those tools cover one brand at a time.
A GamStop exclusion covers none of them. It applies only to operators that participate in the scheme, so an account here is not checked against it at sign-up or at any later point.
Deposit menus at the 5 reviewed casinos not on GamStop range from 5 methods (Koi Spins) to 15 (Goldenbet). Only 2 of them, Cosmobet and Goldenbet, pay out to cards. Processing changes too. Card payments often pass through a third-party processor, so the merchant name on a bank statement may differ from the casino brand. Cryptocurrency runs through the site's own wallet system, with no bank in between.
The methods non GamStop casinos most often carry, with market-standard waits for a verified account:
| Method | Deposits | Withdrawals | Typical wait |
|---|---|---|---|
| Visa / Mastercard (debit) | Yes | At some sites | 1 to 3 business days |
| Skrill | Yes | Yes | Up to 24 hours |
| Neteller | Yes | Yes | Up to 24 hours |
| MiFinity | Yes | Yes | Up to 24 hours |
| Bitcoin | Yes | Yes | Up to 24 hours |
| USDT | Yes | Yes | Up to 24 hours |
| Bank transfer | Yes | Yes | 2 to 5 business days |
A first withdrawal adds the identity check to any of these waits.
Library size across the 5 reviewed brands runs from 2,200 games at Slim King to 7,000 at Cosmobet and Goldenbet, and live tables from 100 to 250. How those games not on GamStop split between categories matters more than the headline game library count.
Slots make up between 78.6% of the catalogue (Cosmobet) and 90.9% (Slim King). Goldenbet carries the most in absolute terms at 5,600, with Pragmatic Play, NetEnt, Play'n GO, Hacksaw, Nolimit City and BGaming among its software providers. Slim King's 2,000 come from less familiar studios such as NetGame, Nucleus Gaming and Apollo Games. Jackpots and bonus-feature games sit inside these totals rather than as separate counts.
Non GamStop slots are where most welcome bonuses get cleared. The stake cap during wagering (£5 at Cosmobet, Goldenbet and Betmica, €2 at Koi Spins) therefore applies to every spin until the requirement is met.
Betmica runs the most live tables at 250, against 100 at Slim King. Live sections at non GamStop casinos of this size usually group blackjack, roulette and baccarat with game shows.
Studio information is uneven. Cosmobet names Evolution and Ezugi, and Goldenbet names Evolution. Betmica's supplier list names no live studio, so the source of its tables is worth checking in the lobby before depositing for live play.
Subtracting slots and live tables from each total leaves the remainder, where table games, crash games, instant games and similar formats sit. Cosmobet carries the most at 1,300 titles, followed by Goldenbet at 1,200. Koi Spins and Betmica hold 250 each, Slim King 100.
A player who prefers quick-round formats to reels gets the broadest choice at a casino not on GamStop with a large remainder. These titles often count less, or not at all, towards bonus wagering. Contribution rates belong on the checklist before playing them with bonus money.
Wagering across the 5 reviewed brands sits at 30x for Cosmobet and 35x for Slim King, Koi Spins, Goldenbet and Betmica. At UK casinos not on GamStop, that multiple is only one of 3 terms that set the real cost:
A worked case at Cosmobet: a £100 deposit matched 100% puts £200 in play. At 30x on deposit plus bonus, that requires £6,000 in bets. At the £5 cap, that is at least 1,200 spins, all inside 7 days.
Before accepting an offer at any non GamStop casino, confirm the base, the stake cap, the deadline and which games count, then judge whether that turnover fits normal play.
The right choice among non GamStop casinos depends less on headline offers than on how a player deposits, bets and withdraws. Three situations show the trade-offs.
A small first deposit to test a site comes first for many players. The thing to check is the entry deposit, then immediately the withdrawal floor. Slim King has the lowest entry point on this page. The cost: its withdrawal floor is several times that entry, and its licence entry is marked unlicensed.
A bonus player wanting turnover kept down should read what the multiple applies to, and the deadline, before the headline percentage. Cosmobet carries the lowest multiple of the group. The cost is a short clearing window and payouts listed in business days rather than hours.
A live-table regular needs the live table count and the studio behind it. Betmica lists the most tables. The cost is a higher withdrawal floor than the Santeda sites and no card withdrawals.
Whatever the situation, the best casinos not on GamStop for a given player are the ones whose terms survive these checks:
A GamStop registration blocks accounts only at operators inside the scheme; casino sites not on GamStop never check it. What these sites offer instead works account by account and covers one brand only:
Set a deposit limit and reminders before the first deposit, not after a losing session. All of these services are 18+, and BeGambleAware offers free, confidential support for anyone whose gambling is becoming a problem.
