Koi Spins Sister Sites

Short answer: yes, Koi Spins has sisters — a lot of them. It is not a one-off site but one brand in a large offshore network that a casino-tracking database links to roughly 70 other online casinos. The company named as running it is Fortune Master Limitada, and the site operates outside the UK on an offshore licence. It does not hold a UK Gambling Commission licence, and it accepts UK players from outside the UK system. That last point is the whole story here, so most of this page is about what that actually means for you rather than about free spins.

Who runs Koi Spins, and what can actually be verified

This is where honesty matters more than a slick review. Koi Spins' own terms and conditions never name the company behind it — the document refers only to "the Company" from top to bottom, and the site footer says nothing more specific than that it operates "under a valid e-gaming licence." There is no company registration number, no registered address, and no licence number printed anywhere on the site itself.

The independent database Casino.guru attributes the brand to an owner and operator called Fortune Master Limitada, licensed in the Comoros by Anjouan Gaming. Some affiliate pages instead describe it as Curacao-licensed and list the owner as "N/A." We could not reconcile those two claims, and — this is the important bit — we could not find a publicly verifiable licence number on the brand's own pages or confirm one on a regulator's register. So treat "Anjouan" as the best available attribution from a reputable tracker, not as something the casino demonstrates to you directly. What is not in doubt is the thing that counts: there is no UK Gambling Commission licence. If you ever see a UKGC logo or a "White Hat Gaming" style UK licence associated with a brand like this, that would be a platform provider's licence, not Koi Spins' own — and it is not present here in any case.

One detail from the terms is worth knowing. Koi Spins blocks players from the Netherlands, France, the USA, Spain, Italy, Ukraine and Georgia — but not the UK. In plain terms, it is happy to take British customers even though it is not regulated to protect them. Know-your-customer identity checks are still mandatory before withdrawals, so this is not a "no-checks" casino; it simply does the checks under its own rules rather than UK ones.

The real sister sites

Because the operator does not publish its own brand family, the only credible source for the network is Casino.guru's ownership grouping, which ties Koi Spins to around 70 interconnected casinos. A representative sample is below. Every one is offshore and sits in the tracker's low safety band — the network as a whole carries a heavy complaint load, which is exactly why Casino.guru marks Koi Spins itself as low-trust.

Two caveats keep this honest. First, this is a sample — the full network runs to dozens more (Rabbit Win, Yeti Win, Bounty Reels, Slots Charm and many others). Second, none of these siblings names its own operator on its own site either, so the grouping rests on Casino.guru's footprint analysis rather than on each brand admitting it. Where you should be sceptical is the "sister sites" lists on other affiliate pages: several name completely different brands — MyStake, Jackbit, Golden Lion, Booming Slots — that do not appear in the ownership grouping at all. Those look like "similar casino" suggestions dressed up as family, and we have left them out.

What playing here actually risks for a UK player

This is the part the bonus banners skip. Because Koi Spins is offshore and not UKGC-licensed:

• No UK complaints route and no fund protection. If a withdrawal is refused or an account is closed with your balance inside it, you cannot escalate to the UK Gambling Commission or a UK alternative dispute resolution (ADR) service. Your only recourse is the operator's own support and, at best, the offshore licensor — and the network's complaint record is poor. Player money is not ring-fenced to UK standards, so "it's in my account" is not the same as "it's protected."
• It sits outside the national online self-exclusion scheme. If you have self-excluded from UK-licensed gambling, that block does not reach Koi Spins — the site is not part of the scheme and will still let you register. For anyone using self-exclusion to stay in control, an offshore site is a gap in the wall, not a loophole to use.
• Deposit limits do not travel with you. Any limits you set are per-account and per-operator. A limit on a UK casino, or on another site in this network, does nothing here; you would have to set one again, if the tool is even offered, and the operator can change its terms without notice under its own rules.
• Offshore bonus terms tend to be heavier. Large headline percentages usually come with steeper wagering, tighter maximum-bet and maximum-cashout clauses, and expiry traps — and there is no UK regulator holding those terms to a fairness standard. The UK's 10× wagering cap simply does not apply here.
• Crypto-first cashflow. The site leans heavily on cryptocurrency alongside cards, and its terms disclaim responsibility for currency-value swings. That adds a layer of volatility and irreversibility that a UK debit-card casino does not.

None of the above is a feature. Each one is a protection you give up by playing outside the UK system, and it is why the independent tracker Casino.guru gives Koi Spins a Low safety score and openly advises players to stay away.

Our honest verdict

If you were searching for Koi Spins' sisters hoping for a "safer" one in the family, there isn't one — they are the same offshore network with the same missing protections. A UK Gambling Commission-licensed site is the safer choice by a wide margin: you get a real complaints and ADR route, deposit and reality-check tools that actually bind, and self-exclusion that works across every licensed operator at once. That is worth far more over time than a bigger opening bonus.
