Reason
The welcome offer is spent
- Does a sister site help?
- Rarely. The 100% up to £1,000 plus 100 spins offer is a one-per-person deal, and the group's terms read the same way across brands.
Monster Casino Sister Sites
Monster Casino is one brand on a licence that carries close to two hundred domains. This page lists the ones the regulator actually names, and is honest about how little changes when you move between them.
- UKGC account 39335
- ProgressPlay Limited
- Register-checked 18 Sep 2026
Monster Casino is a white-label brand on ProgressPlay Limited's UK Gambling Commission account 39335. Its sister sites are simply the other domains listed on that account — Mobile Wins, Vegas Paradise, Fruity King, MrRex, PlayUK, Casino Kings and JeffBet among them. Same licensee, same platform, same complaints route; different skin, different welcome offer.
How the ProgressPlay group actually works
A white label is a rented casino. ProgressPlay holds the licence, runs the platform, holds the player funds, does the identity checks and answers the complaints. The brand owner supplies the name, the artwork and the marketing, and takes a share of the revenue. That is why a group like this can carry dozens of front ends that all feel oddly familiar once you are logged in: the cashier screen, the verification flow and the terms are the licensee's, not the brand's.
The Gambling Commission does not use the phrase “sister site”. What it publishes is a list of domain names attached to each operating licence, and a status flag next to each one. When we read account 39335 on 18 September 2026 it held 193 domains: 95 flagged White Label, 20 flagged Active, and 77 flagged Inactive. Monster Casino itself sits in the white-label column, listed as www.monstercasino.com — note the .com, not the .co.uk address the brand markets under.
That flag is the only reliable definition of a sister site anyone can check. Affiliate lists are usually built by pattern-matching footers and logos, which is how dead brands stay on them for years. The register is updated by the regulator, it is free, and it takes about forty seconds to read.

Why people look for a Monster Casino alternative
Most of the searches behind this page come from five situations, and only two of them are actually solved by moving to a sister brand.
Reason
A payment method is missing
- Does a sister site help?
- No. The cashier belongs to the licensee. Monster Casino lists no MuchBetter and no AstroPay, and a sibling on the same platform will not magically add them.
Reason
Withdrawals feel slow
- Does a sister site help?
- No. Processing is one business day plus one to seven for the transfer, with a 1% fee capped at £3. That is a platform policy, not a brand policy.
Reason
You want a different look or lobby order
- Does a sister site help?
- Yes, that is genuinely what changes. Layout, promotions calendar and the loyalty scheme are the brand owner's decisions.
Reason
You want a different company behind it
- Does a sister site help?
- Only if you leave account 39335 entirely. Inside it, the licensee is ProgressPlay Limited on every single brand.
Reason
You are trying to stop
- Does a sister site help?
- No, and this is the one that matters. Use GAMSTOP, which covers every GB-licensed site at once. See our responsible gambling page.
Who owns Monster Casino
The licensee is ProgressPlay Limited, a Maltese company (registration C58305). The Gambling Commission's register gives the head office as Kolonakiou 26, Office No.18, Agios Athanasios, Limassol 4103, Cyprus — worth knowing, because plenty of affiliate pages still print a London address for this operator that appears nowhere in the regulator's record.

Brand history is messier than the licence history. Monster Casino launched in 2017 under Nektan, moved to Grace Media in 2020, and has sat on ProgressPlay's account since 2021. So a page telling you the casino has been “licensed since 2014” is quoting the licensee's start date, not the brand's. The about page goes through the corporate timeline in more detail.
The May 2025 enforcement action was against the licensee, for anti-money-laundering and social-responsibility failings. It applies to the whole account. Moving from Monster Casino to a sister brand does not move you away from that record — it is the same company, the same compliance function and the same audit condition.
Real sister sites on the same licence
Everything below is copied from the Domain names tab of account 39335, read on 18 September 2026. We have not added a brand because it “looks like” a ProgressPlay site, and we have not removed one because it is obscure.
Flagged White Label — live sister brands
- Mobile Wins
- Vegas Paradise
- Fruity King
- MrRex
- PlayUK
- Casino Kings
- JeffBet (jeffbet.net)
- Mr Jack Vegas
- Mr Slot
- Jazzy Spins
- Hippozino
- Conquer Casino
- Dream Palace Casino
- MaxiPlay
- SpinzWin
- Vegas Mobile Casino
- The Online Casino
- Winissimo
That is a selection, not the whole column — 95 domains carried the white-label flag on the day we looked, and a fair few of them are bingo or lottery front ends rather than casinos.
Flagged Inactive — do not treat these as live
These names still circulate on alternative-site lists, but the register says the operator is no longer running them in Great Britain. If one of them loads and takes a deposit from a UK address, that is a reason to close the tab, not a lucky find.
- Dazzle Casino
- JeffBet (jeffbet.com)
- Fruity King NZ
- Goldman Casino
- SlotJar
- Top Slot Site
- Jackpot Paradise
- SupaCasino
- Pots of Gold
- Mr Vegas Casino
- Lucks Casino
- Soho Casino
Flagged Active — on the account but not white-labelled
A smaller group carries a plain Active flag. In practice these behave like sister sites too, but the register is telling you the arrangement is different, so it is worth noticing the distinction rather than lumping everything together.
- Bubble Bingo
- CasinoMite
- LumoSlots
- Play Magical
- PushBet
- Scorching Slots
- Sunny Casino
- UK Slots
- Yoko Casino
- Glimmer Casino
- Quid Slots

- Quartz Casino
- Anytime Casino
- 21Bets Casino
Same model, different operator
ProgressPlay did not invent the white label, and it is not the only place to find one. If what you actually want is a change of company — a different compliance team, a different complaints route, a different enforcement record — then you need a brand on a different licence account, not a different skin on this one.
Two other GB white-label platforms are easy to verify in the same register:
Platform
Jumpman Gaming Limited
- UKGC account
- 39175
- How it looks to a player
- Dozens of small slot brands sharing one lobby, one cashier and one support inbox. Wild 24 is one of them.
Platform
AG Communications / Aspire Global
- UKGC account
- 39483
- How it looks to a player
- The same pattern at a larger scale; CasinoLuck has run on this account. Brands come and go while the licence stays put.
The method is identical in each case. Take the domain, search the operator in the public register, open the Domain names tab, and read the operator's name at the top of the page. If the name changes, you have genuinely changed company. If it does not, you have changed wallpaper.
Five sites compared
Here is the comparison people ask for, built only from facts a regulator publishes. The interesting result is how little varies.

You will notice what is missing: bonus amounts, game counts, payout speeds, ratings. We left them out on purpose. Those numbers change without notice, none of the sister brands publishes an audited game count, and a comparison table is worse than useless when four of its five columns are guesses. For Monster Casino's own terms, which we have checked, see the bonuses page.
Before and after the switch
This is the table that answers the real question — what is different the morning after you open an account somewhere else in the group.
| What you had at Monster Casino | What you get on a 39335 sister site | Changed? |
|---|---|---|
| Licensee ProgressPlay Limited | Licensee ProgressPlay Limited | No |
| UKGC account 39335 and its 2025 enforcement record | The same account and the same record | No |
| Identity and age checks before you deposit or play | Identical, run by the same platform | No |
| Bonus wagering capped at 10x by UK rules since 19 January 2026 | Capped at 10x — it is law, not a brand promise | No |
| Online slot stakes capped at £5 a spin, £2 for players aged 18–24 | The same caps | No |
| Withdrawal processing of one business day plus one to seven days to arrive | The same processing chain and the same 1% fee capped at £3 | No |
| Complaint to the brand, then the named ADR after eight weeks | Same licensee, same complaints policy, same ADR | No |
| Welcome offer: 100% up to £1,000 plus 100 spins, £20 minimum deposit, 10x, 30 days for the bonus and 7 for the spins | A different offer with different numbers — read it on the site, never from a list | Yes |
| Monster Casino's promotions calendar and loyalty scheme | The brand owner's own calendar and scheme | Yes |
| This lobby layout, artwork and default game order | A different skin over a heavily overlapping library | Yes |

Who this is not for
A switch makes sense if
- You simply prefer another brand's interface, promotions calendar or loyalty scheme.
- You have never held an account in the group and want to read two welcome offers before choosing one.
- You want to stay with a GB licensee and are comfortable that the licensee will be the same company.
Look elsewhere if
- You have self-excluded or you are trying to cut down. Register with GAMSTOP instead; it covers the entire GB-licensed market in one step.
- You are hoping for a second welcome bonus. One platform, one set of anti-abuse checks, one very predictable outcome.
- Your complaint is unresolved. Finish it — opening a new account with the same licensee does not reset anything.
- You want a different regulator or a different company. You need a different licence account, not a different skin.
Licence checker
No search box, no lookup that happens on our server. Every row below is a link straight into the regulator's own record, so you can confirm the operator name and the domain list yourself. If a brand is not in a register, no amount of badges on its footer makes it licensed.

- Open the register and search the operator name, or the account number if you already have it.
- Check the status of the licence on the summary page — Active is the only one that counts.
- Open the Domain names tab and find the exact address you are about to type into a browser.
- Read the flag next to it. White Label and Active are live; Inactive means the operator has stopped running it for GB players.
- Check the Regulatory actions tab while you are there. It is short, it is public, and it tells you more than any review.

Sister sites FAQ
The questions that come up most often once people realise how the group is structured.
What are Monster Casino's sister sites?
They are the other domains registered to ProgressPlay Limited under UK Gambling Commission account 39335. On 18 September 2026 the white-label group included Mobile Wins, Vegas Paradise, Fruity King, MrRex, PlayUK, Casino Kings, JeffBet, Mr Jack Vegas, Mr Slot, Jazzy Spins, Hippozino and Conquer Casino, among about ninety others.
How can I check a sister site myself?
Open the Gambling Commission public register, search the operator by name or account number, then open the Domain names tab. Every website that operator may offer in Great Britain is listed with a status of Active, Inactive or White Label. If a domain is not on the list, the operator is not licensed to offer it here.
Is a sister site safer than Monster Casino?
No. A site on the same account carries exactly the same protections and exactly the same history, including the warning, extra licence condition and £1,000,000 penalty recorded against ProgressPlay Limited on 9 May 2025. Safety differences appear when the licensee changes, not when the logo does.
Can I claim a second welcome bonus on a sister site?
Treat that as a no. Sister brands share a platform, a payment processor and a set of terms limiting the offer to one per person, household, device and payment method. Duplicate accounts inside one group are the easiest kind of abuse to spot, and losing the winnings is the normal outcome.
Does self-exclusion carry across the group?
GAMSTOP does the job properly: one registration blocks every Gambling Commission licensed site, inside account 39335 and far beyond it. A limit or exclusion set inside a single casino account is narrower than that. If the point is to stop, use GAMSTOP rather than moving brands.
Do sister sites have different games?
The lobbies are built from the same supplier integrations, so the overlap is heavy and the ordering on the front page is usually the visible difference. Monster Casino does not publish a game count or a full supplier list, so neither do we — and we would not trust a sister-site comparison built on numbers nobody has confirmed.
Where does a complaint go if a sister site refuses to pay?
The licensee is the same company, so the route is the same. Complain in writing to the brand first. If it is unresolved after eight weeks, or you reach deadlock sooner, take it to the alternative dispute resolution provider named in that site's complaints policy. The Gambling Commission logs complaints but does not arbitrate individual disputes.
Why do affiliate lists disagree with the register?
Because most of them were written once and never re-read. Dazzle Casino, JeffBet's .com address and Fruity King's New Zealand domain all still appear on “sites like Monster Casino” lists, and all three were flagged Inactive when we checked. The register costs nothing to open and settles the argument.
Stay with the brand you can actually check
Monster Casino's licence, its operator and its enforcement record are all a click away in the public register — which is more than most alternatives can say. New players get 100% up to £1,000 plus 100 spins at 10x wagering, with a £20 minimum deposit.
