About Mamako
An independent review desk that ranks non-UK casinos from a UK player's seat — real deposits, real withdrawals, and bonus terms read in full.
Who we areAn independent desk for UK players going offshore
Mamako is an editorial review desk covering online casinos that are licensed outside the United Kingdom but still accept UK players. We are not a casino, we do not take bets, and we hold no gambling licence of our own. What we do is test these offshore operators the way a returning player actually uses them — open an account, deposit real money, play real sessions, and then request a withdrawal — and publish what we find.
The reason this desk exists is simple. Once you step outside the UK Gambling Commission's remit, the guard rails that normally sit between a player and a bad operator are lighter. There is no GAMSTOP link, no mandatory affordability check and no regulator-backed complaints route. The diligence the UKGC would otherwise do falls to you — and that is exactly the gap we try to close with a ranking you can actually trust.
IndependenceHow we stay impartial — and how we pay the bills
We are transparent about commercial relationships because hiding them would defeat the point. When you sign up to a casino through one of our links we may earn a commission, at no extra cost to you. That funding keeps the desk running, but it does not buy a position in the table. The order is set by testing, not by who pays the most — and an operator that stalls a payout or buries its terms drops regardless of any commercial arrangement.
Where we cannot verify something ourselves, we say so. Where an operator changes its terms after we have reviewed it, we update the page. If we get something wrong, we want to hear about it — see our contact page for how to flag a correction.
MethodologyWhat we actually test
Every site is assessed from the seat of a UK player who deposits, plays and then cashes out. Marketing copy does not move the ranking; the cashier does. Four factors carry the most weight:
1. Withdrawal limits and cashier speed
We check the published monthly and per-transaction limits, then time a real withdrawal. Crypto and e-wallet rails that clear within hours score highest; sites that lean on slow verification to delay payouts lose ground.
2. Payment flexibility
We want debit cards, established e-wallets and crypto (BTC, ETH and stablecoins such as USDT) all on the table, with the minimum deposit clearly stated.
3. RTP and variance transparency
We favour casinos that publish RTP ranges and carry the recognised studios at their proper return figures, rather than stripped-down, low-RTP builds of popular slots.
4. Honest bonus terms
A headline match means nothing if the wagering is hidden or the game weighting is punitive. We read the requirement, the maximum bet while a bonus is active, and the cashout cap.

One last thingPlay within your limits
Offshore casinos do not enforce UK self-exclusion. If gambling has stopped being entertainment, the right move is the help on our responsible gambling page, not a new account. Everything here is for players who are 18 or over.
