Rockbet and 5 other casinos, Casino Fiz, Tradition Casino, Gibson Casino, Supreme Play and EuroFortune, run on the same Rival platform with the same site files and near-identical terms, but none of the 6 names the company behind it or shows a licence number. This page is for a player who already knows Rockbet and wants to know which brands sit around it, how close they really are and whether the differences are worth acting on. The short answer is that the lobby and the 978-game catalogue are the same on all 6, so the real differences are the welcome offer, the withdrawal rules and who each site will accept. Because no operator is disclosed, we could not run the usual ownership check, and this page compares the brands on their published terms instead.
The Gambling Commission requires any operator offering remote gambling to consumers in Great Britain to hold a Commission licence, including operators based overseas. None of the 6 brands holds one, so none is authorised to serve players in Great Britain. Rockbet's terms let UK residents choose sterling and leave the UK off its restricted-country list, which changes nothing about that licensing position.
A note on money: welcome offers display in euros, and the terms quote limits in €, $ and £ side by side as the same number of "credits". Treat the euro figure as the published offer rather than a converted sterling amount, because the figure that applies follows your account's currency.
Which Rockbet sister site fits which player
The table starts with what each brand does differently from Rockbet and the restriction to check before signing up. Welcome offers sit in a separate table further down, because a shared cash-out rule decides how much any of them is worth.
| Brand | Main difference from Rockbet | Important restriction | Min deposit |
|---|---|---|---|
| Casino Fiz | 400% welcome, weekly tournaments | Approval can take 18 working days | €5 or €10 by method |
| Tradition Casino | 400% welcome, weekly tournaments | Approval can take 18 working days | €5 or €10 by method |
| Gibson Casino | 400% welcome, no tournament card | Approval can take 18 working days | €5 or €10 by method |
| Supreme Play | 400% welcome, slightly reworded terms | Approval can take 18 working days | €5 or €10 by method |
| EuroFortune | 400% welcome, separate support domain | Approval can take 18 working days | €5 or €10 by method |
What existing Rockbet players need to know
Two points matter more to a Rockbet player than any welcome figure: how the account rules treat the other brands, and how much of a win the shared cash-out rules let you take home.
Welcome bonus eligibility
Rockbet permits one account per person, household, IP address, email address or computer "at each of its casinos". Its list of prohibited duplicate accounts includes "more than one account on an affiliated sister casino under the same management as Rockbet", and it can act on links to closed or refunded accounts "on any brand within the Rival network". The other 5 brands use a shorter rule of one account per household at each of their casinos. None of the 6 names its sister casinos, so we could not establish which brands the Rockbet clause covers, and you should not assume a second welcome on this platform will be honoured.
If you have already used Rockbet's welcome, the recurring terms are what matter, and on this platform they are the same everywhere. Every brand pays cashback at 1x wagering with withdrawals capped at 10 times the cashback, and cashback from tournaments, raffles or promotions it calls "special" is capped at 2 times. Casino Fiz, Tradition Casino and Supreme Play add weekly tournaments, and all 5 sister brands run a weekly raffle and a next-day cashback offer called Cashtravaganza that Rockbet does not list.
Accounts, verification and withdrawals
Each brand needs its own account, and the terms give no sign that balances or verification carry from one to another. All 6 ask for photo ID, a utility bill and copies of any card used before they approve a withdrawal, and a withdrawal is cancelled if the documents are not sent within 30 days. We could not establish whether a verification passed at one brand is accepted at another.
Verify before you deposit rather than after a win. Complaints about offshore casinos often follow the same pattern: verification is requested only at the first withdrawal and the payout stalls while documents are checked. On this platform that wait comes on top of approval periods of up to 12 working days at Rockbet and up to 18 at the other 5.
How the sister sites compare
The figure that matters most is the cash-out cap on deposits, not the welcome percentage. All 6 brands limit withdrawals from any deposit of 249 or less to 10 times that deposit for the play session, and cap any bonus of 200% or more at 10 times the deposit. A £50 deposit that runs to a £2,000 balance therefore pays out no more than £500, and the rest is removed as "non-withdrawable". That is arithmetic on the stated terms, not a live offer.

The sections below cover the 5 sister brands. None of them gives a launch date, so they are ordered by how far each moves from Rockbet.
Casino Fiz
Casino Fiz uses the same lobby, cashier and 978-game catalogue as Rockbet, and leads with a 400% first-deposit bonus or 100% cashback insurance. The bonus cap and wagering sit behind the login, so we record both as not documented. Deposits start at €5 or €10 depending on the method.
The difference from Rockbet is in the withdrawal clauses rather than the games. Casino Fiz has no weekly withdrawal limit, no Bitcoin-only rule for UK players and an age limit of 18, where Rockbet sets 25. Its approval period runs to 18 working days against Rockbet's 12, and the monthly cap of 10,000 credits and 1,500 per withdrawal is the same on both.
For a Rockbet player who wants a larger percentage match and weekly tournaments, Casino Fiz is the closest alternative. A player hoping the 400% figure means a larger cash-out gains nothing, because the 10x-deposit cap applies to both.
Tradition Casino
Tradition Casino matches Casino Fiz line for line: the same 400% welcome or 100% cashback insurance, the same weekly raffle, Cashtravaganza and tournaments, and the same minimum deposit. We found 111 of its 115 terms sentences word for word in Rockbet's terms.
Nothing in Tradition's published terms separates it from Casino Fiz apart from the brand name and the support address. The withdrawal rules, the 120-day dormancy forfeit and the 3% to 6.5% fee the casino reserves for card deposits are identical.
For a Rockbet player, Tradition Casino earns its place only as a different name on the same terms. A player who already has an account at Casino Fiz gains nothing by opening one here.
Gibson Casino
Gibson Casino carries the same 400% welcome, cashback insurance, raffle and Cashtravaganza, but its promotions page showed no tournament card when we checked in October 2026. Its terms match Casino Fiz sentence for sentence, and deposits start at €5 or €10.
The missing tournament card is the only visible difference from the rest of the group. Gibson keeps the same 18-working-day approval period, the same €50 minimum withdrawal and the same 10-40 €/$/£ transfer fee on every withdrawal.
For a Rockbet player who wants the 400% welcome without tournaments, Gibson Casino is a like-for-like option. A player who values tournaments gains nothing over Casino Fiz here.
Supreme Play
Supreme Play runs the same offer set as Casino Fiz, including tournaments, with the same minimum deposit. Its terms show the lowest match in the group, 103 of 116 sentences against Rockbet, because its referral and definition clauses name it "Supreme Play Casino" in full.
That naming difference does not change the rules a player meets. The withdrawal cap, approval period, dormancy forfeit and account rule are the same as at Casino Fiz.
For a Rockbet player, Supreme Play is worth its place only as another name on the platform. A player looking for different terms gains nothing here, because the cash rules are the same as everywhere else in the group.
EuroFortune
EuroFortune shows the same 400% welcome, cashback insurance, raffle and Cashtravaganza, with no tournament card, and the same deposit range. It is the only brand whose support address sits on a different domain, eurofortunegames.com, rather than the casino's own.
Its terms otherwise match Casino Fiz in full. The approval period, withdrawal cap, transfer fee and household account rule are all the same.
For a Rockbet player, EuroFortune is a like-for-like option on different branding. A player expecting a different operator gains nothing, because the terms give no sign of one.
Welcome offers and payment terms
The table separates the bonus win cap, which limits what a bonus can turn into, from the monthly ceiling, which limits total cash-out. Figures that sit behind the login are marked as such.

| Brand | Welcome (with wagering) | Bonus win cap | Monthly ceiling | Card withdrawals |
|---|---|---|---|---|
| Rockbet | 200% up to €2,000 or 100% cashback insurance; wagering not documented | 10x the deposit | 10,000 credits; €1,000 a week once verified | No for UK players (Bitcoin only) |
| Casino Fiz | 400% or 100% cashback insurance; cap and wagering not documented | 10x the deposit | 10,000 credits, 1,500 per withdrawal | Listed, 10-40 fee |
| Tradition Casino | 400% or 100% cashback insurance; cap and wagering not documented | 10x the deposit | 10,000 credits, 1,500 per withdrawal | Listed, 10-40 fee |
| Gibson Casino | 400% or 100% cashback insurance; cap and wagering not documented | 10x the deposit | 10,000 credits, 1,500 per withdrawal | Listed, 10-40 fee |
| Supreme Play | 400% or 100% cashback insurance; cap and wagering not documented | 10x the deposit | 10,000 credits, 1,500 per withdrawal | Listed, 10-40 fee |
| EuroFortune | 400% or 100% cashback insurance; cap and wagering not documented | 10x the deposit | 10,000 credits, 1,500 per withdrawal | Listed, 10-40 fee |
What you keep when you switch, and what changes
You keep almost everything. All 6 brands use the Rival platform, the same lobby layout, the same 978-game count and the same footer payment logos for Visa, Mastercard, Neteller, Skrill and Bitcoin. They also share one site-text file, byte for byte, the 10x-deposit cash-out cap, the €50 minimum withdrawal, the 10-40 transfer fee and the rule that forfeits the balance after 120 days without logging in or placing a bet. Affiliate lists that present these as separate casinos with their own libraries are describing one catalogue under 6 names.
The differences are short. Rockbet offers 200%, the rest 400%. Rockbet limits verified players to €1,000 a week. Rockbet pays UK players in Bitcoin only. Rockbet sets the age limit at 25. Casino Fiz, Tradition and Supreme Play run tournaments. Gibson and EuroFortune do not list them. What is not shared is just as important: registrations, balances, verification and any self-exclusion stay with the brand where you set them up.
How the ownership links were checked
Our usual test for a sister site is the footer: the same legal entity and the same licence reference on both brands. These 6 brands fail it by design, because none shows either. Each About page says only that the casino is "owned and operated by an incorporated corporation organized licensed and regulated by the Government of Curacao". The shared site-text file holds a line for a Curaçao licence number, but none of the 6 sites displays it.

We matched the brands on what they do publish instead. All 6 serve the same site-text file, byte for byte, and between 103 and 111 sentences of each sister's terms appear word for word in Rockbet's. Rockbet's own terms refer to "an affiliated sister casino under the same management" without naming it. This is strong evidence of a shared platform and management, not proof of a common owner, and you can repeat the test by reading the terms and the withdrawal clauses side by side.
Some names found on affiliate lists do not hold up. Casino Lust, FatBet and Casholot now point to parked domains offered for sale, Crazy Luck refused the connection and Royal Planet loaded without any terms text when we checked on 6 October 2026. Affiliate reviews name TVMUK Ltd, licence 8048/JAZ, or SSC Entertainment N.V. as the operator, but none of the 6 sites shows either name, so we treat both as unverified. The shared site file also holds an unused paragraph naming Windward Circle B.V. and application OGL/2024/1135/0484, which the Curaçao Gaming Authority's 21 September 2026 registry lists as "Assessment in progress". None of the 6 sites displays it, so we could not tie that company to them.
Risks, protections and self-exclusion
Playing at any of these brands means giving up the safeguards a Gambling Commission licence brings: enforced deposit limits, free and independent dispute resolution, affordability checks and the rules on how bonuses and withdrawals must work. With no named operator, you also have no company to complain to beyond the casino's own support address. A licensed operator in Great Britain cannot limit withdrawals from your own deposit balance, which is what the 10x-deposit cap does.
GAMSTOP does not cover these sites, and a self-exclusion at Rockbet does not carry to its sister brands. If you have registered with GAMSTOP, these sites sit outside the protection you chose, and that exclusion exists for a reason. Free, confidential support is available from GamCare and the National Gambling Helpline on 0808 8020 133, and you can register or check a self-exclusion with GAMSTOP.
If you play offshore regardless, verify your identity as soon as you sign up rather than waiting for a withdrawal. Read the 10x-deposit cap, the withdrawal limits and the transfer fee before depositing money you would mind losing.
Common questions
Who operates Rockbet and its sister sites?
Not disclosed. Each brand says only that it is run by a corporation licensed and regulated by the Government of Curaçao, and none shows a company name or licence number.
How many sister sites does Rockbet have?
5 that we could match on their published terms: Casino Fiz, Tradition Casino, Gibson Casino, Supreme Play and EuroFortune. All 6 share the Rival platform, one site-text file and near-identical terms.
Can I claim a welcome bonus at more than one sister site?
Not safely. Rockbet's terms treat an account at "an affiliated sister casino under the same management" as a prohibited duplicate, and the other brands allow one account per household at each of their casinos.
Are any Rockbet sister sites licensed by the Gambling Commission?
No. None of the 6 brands holds a Gambling Commission licence, so none is authorised to serve players in Great Britain.
Does a Rockbet self-exclusion cover the sister sites?
No. A self-exclusion stays with the brand where you set it up, and GAMSTOP does not cover any of these sites.
Do I need a separate account for each sister site?
Yes. Each brand needs its own registration and verification, and balances are not shared between them.
Which sister site has the largest welcome bonus?
Casino Fiz, Tradition Casino, Gibson Casino, Supreme Play and EuroFortune all advertise a 400% first-deposit bonus against Rockbet's 200% up to €2,000. Every brand caps a bonus of 200% or more at 10 times the deposit, so the larger percentage does not raise the cash-out.
Is Casino Lust a Rockbet sister site?
Not any more. casinolust.com now points to a parked domain offered for sale, as do FatBet and Casholot, so none of them is a live sister brand.
