Quartz Casino is operated by ProgressPlay Limited on Gambling Commission account 39335, where the register lists its domain as Active, and its footer still names the operator's former Valletta address, two Class 1 Malta licences from 2012 and 2014 and a copyright line reading Material Copyright © 2016 Quartz Casino.
The short answer
ProgressPlay Limited runs 115 brands, and 18 Quartz Casino sister sites are reviewed here: Casino Kings, Vegas Mobile Casino, Fruity King, Conquer Casino, Monster Casino, Wombat Casino, JeffBet, TheOnlineCasino, Mobile Wins, Power Slots, Dream Palace, Royal Swipe, Bluefox Casino, Casimpo, Funky Jackpot, PlayUK, SlotSite and 21BetsCasino. All 18 of them, and Quartz Casino itself, are operated by ProgressPlay Limited on a single UK Gambling Commission account, 39335.
Compare all 18Pros
- Prints its GB licence in full format, 000-039335-R-319313-001, where its siblings give only the account number
- Listed Active on the register, so the brand and the licensee are the same party
- Does not country-switch its offer, so every visitor sees the same string
Cons
- The licensing footer names the operator's former Valletta address, not its current registered office
- It cites two Class 1 Malta licences from 2012 and 2014 instead of the operator's current MGA licence
- Its own material is dated: "Material Copyright © 2016 Quartz Casino."
Screenshot coverage on this page
No screenshots yet: the ScreenshotOne allowance has been exhausted since 28 October 2026 and resets on 7 November. Written from the homepage, its promotions page and the register. The footer is the slot that matters for this brand rather than the hero — the decade-old address, the superseded Malta licences and the 2016 copyright line are the finding, and they sit at the very bottom of the page where a homepage-only capture would miss them. Everything described below was read from Quartz Casino's own English pages; we would rather show you no picture than the wrong casino's.

How we verified the Quartz Casino sister sites
4 of 5 signals matched, for a fingerprint of 90/100 (confirmed). How the signals are weighted.
Sister-site verification
How we know Quartz Casino shares an operator with these brands
Shared licence numberweight 40%
www.quartzcasino.co.uk is listed against UK Gambling Commission account 39335, ProgressPlay Limited, with status Active on the register's 2026-10-29 export. Active means the licensee runs this one as its own brand rather than on a partner's behalf, so the name on the page and the name on the licence are the same company. The same account carries 115 live domains.
SourceIdentical T&C clausesweight 25%
The welcome terms set one limit across the whole estate, in the operator's own words: "Limited to 5 brands within the network." The sportsbooks on the licence carry the stricter version, "Limited to 1 sport & 5 casino brand/s within the network." The shared rulebook also caps stake while wagering at "A total amount of £5 per spin", excludes Skrill and Neteller deposits from qualifying, and names eCOGRA as the free dispute service on every brand.
SourceSame platform fingerprintweight 15%
Game art, promotion banners and payment icons all come from one host, data.progressplay.net, on every brand reviewed on this licence. This brand's lobby, sign-up or promotion pages run on quartzcasino.casino-pp.net. The newer half of the estate is one deployment outright: eight domains serve an identical Next.js build, n3pP7pFODVxaggF7sGQk3, with an identical stylesheet hash.
SourceShared support infrastructureweight 10%
Two brands on this licence publish a support address and it is the same mailbox — customersupport@instantgamesupport.com — on a domain belonging to neither of them, with JeffBet giving the same one in September. Three brands publish a sister-site page at /sister-sites/ naming 18 of their siblings, and Hippozino's states the account rule outright: "Each one keeps its own accounts, too. Your Hippozino login won't open the door next door, so register separately at any sister site you'd like to explore."
SourceShared payment processorweight 10%not established
Not established. No logged-in cashier has been opened on any brand on this licence, so no processor comparison exists. What is public is the shared icon set — every brand's payment logos are served from data.progressplay.net/content/general/paymentmethods/ — and one shared exclusion, Skrill and Neteller deposits never qualifying for a welcome offer. PlayUK is the only brand of the nineteen to publish a payments table, and it prints a 15% deposit fee on PayViaPhone.

About Quartz Casino
Quartz Casino is the clearest evidence on this licence that ProgressPlay builds brands in generations and then leaves the old ones running. Its footer reads: "Quartz Casino is operated by ProgressPlay Limited of Suite 1258, 28/19 Vincenti Buildings, Strait Street – Valletta VLT1432 – Malta" — the operator's former registered office, where its eleven siblings in this round all print Soho Office, 3A, Punchbowl Centre, Elia Zammit Street, St. Julians, STJ3154, Malta. It then cites two Class 1 Malta licences, MGA/CL1/857/2012 and MGA/CL1/957/2014, issued in 2012 and 2014, where every other brand cites the current MGA/B2C/231/2012. Above all of it sits the line "Material Copyright © 2016 Quartz Casino."
One part of that footer is more precise than anything its siblings publish: the GB licence appears in full format as 000-039335-R-319313-001, where the others give only the account number 39335. The two agree — the account number sits inside the full reference — so this is a stale page rather than a wrong one. It is still a page telling a 2026 player about a 2014 licensing arrangement.
The offer matches the vintage. "Welcome Bonus 100% up to $/€/£ 200" is one string serving three currencies to every visitor, with no wagering figure, no conversion ceiling, no minimum deposit and no expiry anywhere on the page — just a "Full Terms Apply" link into a hash-routed lobby. Of the twelve brands reviewed in this round, eleven print at least a wagering rate; this one prints none.
The lobby itself is served from quartzcasino.casino-pp.net, the operator's platform domain, using hash routes like #promotions/wb100-200 — the oldest navigation pattern seen across the twelve, and the plainest statement of where the site actually lives. The game tiles are current even where the chrome is not: Street Fighter II, Monopoly Megaways, Centurion Megaways, Berryburst, Mighty Hot Wilds and Riddle Reels were all on the page, against a claimed library of just over 300 slots — the smallest figure on the licence.
Like 21BetsCasino, Quartz is listed Active on the register rather than White Label, so this is ProgressPlay's own brand rather than a partner's. That makes the stale footer harder to explain away: there is no third party to blame for not updating it, and the operator's current Malta address has been published by its other brands throughout.
On trust, this is the weakest-presented brand of the twelve without being the worst-behaved. The licence underneath is real, current and the same one its siblings hold. But a player arriving here is told about an address the company left, licences it no longer cites, and material dated 2016, and is shown an offer with no wagering or conversion terms at all. The licensee's record — a 2022 settlement, a 2025 penalty with an official warning and a mandatory third-party audit, and a 2024 ASA ruling — applies here as everywhere on account 39335.

The footer gives the operator's old Valletta registered office instead of the St Julians one its eleven siblings print, cites two Class 1 MGA licences from 2012 and 2014 rather than the current MGA/B2C/231/2012, and dates its own material to 2016. The one element that is unusually precise is the GB licence, printed in full format as 000-039335-R-319313-001. (3 sources)

Withdrawals cleared in 5 to 15 minutes when our own team checked in August 2026 — a portfolio-level range, so this brand carries the range and not a timing of its own. Capped at 78 because speed was the only input recorded. (1 source)
Bonus fairness20% weight

A single tri-currency string — "Welcome Bonus 100% up to $/€/£ 200" — with no wagering figure, no conversion ceiling, no minimum deposit and no expiry published on the page. Alone among the twelve it does not country-switch the offer at all; it simply shows all three currencies to everyone and sends the reader to a hash-routed lobby page for the terms. (2 sources)

The register's export of 2026-10-29 lists 191 domain rows against Gambling Commission account 39335, ProgressPlay Limited: 20 Active, 95 White Label and 76 Inactive, so 115 sites a player can open today. Of the twelve brands reviewed in this round, ten carry status White Label and two — 21betscasino.com and quartzcasino.co.uk — are Active. White Label is the register's own term for a site the licensee runs on a third party's behalf: the brand belongs to a partner, while the licence, the player's contract and every regulatory obligation stay with ProgressPlay.

The Gambling Commission has acted against this licensee twice for the same categories of failure. In May 2022 it announced a £175,718 regulatory settlement from the company, which it described as running 201 websites. In May 2025 it decided a £1,000,000 penalty with an official warning and a licence condition requiring a third-party audit, for anti-money-laundering and customer-interaction breaches between August 2021 and August 2024. Separately, the Advertising Standards Authority upheld a complaint in May 2024 (A23-1223286) against ProgressPlay trading as JeffBet: "New Players Only" was misleading where only players new to the whole network qualified. None of this is recorded against any individual brand; all of it governs every brand on the account.

Quartz Casino's footer carries a licensing paragraph a decade out of date. It reads "Material Copyright © 2016 Quartz Casino. Quartz Casino is operated by ProgressPlay Limited of Suite 1258, 28/19 Vincenti Buildings, Strait Street – Valletta VLT1432 – Malta. ProgressPlay is a limited liability company registered in Malta (C58305), that operates under a Class 1 on 4 license [number MGA/CL1/857/2012 issued on 16th April 2013] & [number MGA/CL1/957/2014 issued on 19th April 2014] issued by Malta Gaming Authority and is licensed and regulated by the UK Gambling Commission, License Number: 000-039335-R-319313-001; UK persons wagering via the website are doing so in reliance on the license issued by the UK Gambling Commission." Its eleven siblings in this round all print the operator's current St Julians address and MGA licence MGA/B2C/231/2012 instead. The GB licence reference is the one element more precise than theirs: they give only the account number.

Quartz Casino advertises "Welcome Bonus 100% up to $/€/£ 200" as a single string containing all three currencies, and is the only one of the twelve brands reviewed in this round that does not serve a country-switched version of its offer. No wagering rate, conversion ceiling, minimum deposit or expiry is published on the page; the only route to terms is a "Full Terms Apply" link to quartzcasino.casino-pp.net/#promotions/wb100-200, a hash-routed lobby on the operator's platform domain whose URL names the offer wb100-200. Its meta description claims "Over 300 of the best online slots", the smallest library figure of the twelve.

The operator caps how many of its own brands a player may claim a welcome offer at, and prints the limit in the offer itself: "Limited to 5 brands within the network." Counted across the twelve brands reviewed here, it appears on nine: TheOnlineCasino, Power Slots, Dream Palace, Royal Swipe, Bluefox Casino, Casimpo, Funky Jackpot, PlayUK and 21BetsCasino. The three without it are Mobile Wins, SlotSite.com and Quartz Casino. The sportsbook version is stricter still — "Limited to 1 sport & 5 casino brand/s within the network." — and appears on four: TheOnlineCasino, Mobile Wins, Funky Jackpot and PlayUK. On TheOnlineCasino, Funky Jackpot and PlayUK both clauses sit on the same page, one under the casino offer and one under the sports offer. In the page source the word "network" is a hyperlink, and it points at the Gambling Commission's own domain list for account 39335.

Four link their welcome terms at the same platform path, /promotion/wl-uk-welcome-offer-panetcir/ — a slug that reads as "white label UK welcome offer" and is the operator's own naming rather than any brand's.

Two of the twelve publish a support address, and it is the same one — customersupport@instantgamesupport.com — on a domain belonging to neither brand and to no brand on the licence. PlayUK prints it in a contact table beside "Live Chat: Available 24/7 when logged in"; UK Slots prints it beside a 24/7 live-chat claim. JeffBet gave the same address in September, which makes three brands and one mailbox.

Three brands on this licence publish their own sister-site page at /sister-sites/ and link it from their footers: jazzyspins.com, hippozino.com, maxiplay.com. Between them the three name 18 sibling brands in three product groups — sportsbooks BetDukes and MaxiPlay; casinos Dukes Casino, Hippozino, JazzySpins, Millionaire, Monkey Casino, Mr Jack Vegas, Mr Mobi, Mr Slot, Mr Super Play, Slot Lux, Wombat Casino; and bingo rooms Chit Chat Bingo, Panda Bingo, Queens Bingo, UK Bingo, Vampire Bingo, Wombat Bingo. Hippozino's version states the account rule outright: "Each one keeps its own accounts, too. Your Hippozino login won't open the door next door, so register separately at any sister site you'd like to explore." and the platform claim just as plainly: "Every site here runs on the same platform as Hippozino, so the cashier, your account tools and support will feel familiar from the first visit." None of the twelve brands reviewed in this round appears on those lists, and only Wombat Casino of the seven reviewed in September does — the operator's own sister-site page covers 18 of its 115 live domains.

The newer half of this estate is one deployment. 35 of the 108 live domains probed served a about 4.5 KB client-rendered application shell rather than a page, and eight of those shells — placebet.co.uk, bubble.bingo, casinomite.com, playmagical.com, pushbet.co.uk, yokocasino.com, www.quidslots.com, www.betsteve.com — carry an identical Next.js build identifier, n3pP7pFODVxaggF7sGQk3, and an identical stylesheet hash, 82b69c9c5af32289. A build identifier is minted once per compilation, so eight different domains serving the same one are serving the same build. Each shell also names its own tenant in its page data, as "whiteLabelName": the operator labelling the white label.

Quartz Casino pros and cons
Pros
- Prints its GB licence in full format, 000-039335-R-319313-001, where its siblings give only the account number
- Listed Active on the register, so the brand and the licensee are the same party
- Does not country-switch its offer, so every visitor sees the same string
- Current games — Monopoly Megaways, Starburst, Centurion Megaways — behind an old page
- A small, plain lobby with no upsell clutter
Cons
- The licensing footer names the operator's former Valletta address, not its current registered office
- It cites two Class 1 Malta licences from 2012 and 2014 instead of the operator's current MGA licence
- Its own material is dated: "Material Copyright © 2016 Quartz Casino."
- No wagering rate, conversion ceiling, minimum deposit or expiry is published for its welcome offer
- Just over 300 slots claimed — the smallest library on the licence
- No support channel or contact route appears on the homepage
What Quartz Casino lacks
- Any published wagering or conversion terms for its own welcome offer
- A published support channel, contact route or hours
- A responsible-gambling destination in its own navigation
- Any named game studio
- Any on-site mention that 114 other brands share its licence
Common complaints about Quartz Casino
A four-figure headline that converts to two figures
commonSeveral brands on this licence advertise a package in the hundreds or thousands and then cap what the bonus can turn into at one times the bonus, or at £20 from free spins. The headline is not a lie and the cap is not hidden, but they sit at opposite ends of the same paragraph, and the second number is the one that decides what the offer is worth.
Welcome small print on the twelve homepages, read 2026-11-05
Running out of welcome offers across the network
occasionalThe operator allows a casino welcome at five brands on the licence and a single sports welcome across the whole account. With 115 live domains, a player who moves between brands can use the allowance up without ever being told they are approaching it, because the limit is printed in the offer rather than shown against the account.
The welcome small print, which states the cap
Depositing with Skrill or Neteller and losing the offer
commonThe shared welcome terms exclude Skrill and Neteller deposits from qualifying. Both are accepted for ordinary play and both appear in the payment icons, so the deposit succeeds and the bonus simply does not arrive. PlayUK is the only brand of the twelve that says so in plain words outside the small print.

The licensee's regulatory record
rareTwo Gambling Commission outcomes against the operator for overlapping failures — a settlement in 2022 and a penalty, warning and mandatory third-party audit in 2025 — plus an upheld ASA ruling in 2024 about how the network-wide welcome rule was presented. The audit condition is a real corrective, but the repetition is what the regulator itself drew attention to.

Quartz Casino Sister Sites — the verdict
Quartz Casino is worth reading as evidence more than as a casino. Its footer tells a 2026 player that ProgressPlay operates from a Valletta address it has since left, under two Class 1 Malta licences from 2012 and 2014 rather than the licence its eleven siblings cite, beneath a copyright line dated 2016 — and the register lists this domain as Active, so there is no white-label partner to blame for the neglect. The offer is of the same vintage: 100% up to $/€/£200 as a single string, with no wagering rate, no conversion ceiling and no minimum deposit published anywhere. What is current is the game list, which carries Monopoly Megaways and Centurion Megaways behind all that, and the licence itself, printed more precisely here than on any sister site. If you want a ProgressPlay brand whose terms you can actually read before depositing, PlayUK and TheOnlineCasino are on the same account; if you want to understand how this estate is maintained, start here.

Quartz Casino sister sites — FAQ
Is Quartz Casino still licensed?
Yes. quartzcasino.co.uk is listed on the Gambling Commission register against account 39335, ProgressPlay Limited, with status Active on the 2026-10-29 export, and the footer prints the licence in full as 000-039335-R-319313-001 — which contains that same account number. What is out of date is the rest of the paragraph: the Malta address, the MGA licence references and a copyright line reading Material Copyright © 2016 Quartz Casino.
What is Quartz Casino's welcome offer and what does it cost?
The page advertises "Welcome Bonus 100% up to $/€/£ 200" and publishes nothing else: no wagering rate, no conversion ceiling, no minimum deposit and no expiry. The only route to those terms is a "Full Terms Apply" link into a hash-routed lobby page on the operator's platform domain. Eleven of the twelve brands reviewed in this round print at least a wagering rate on the page itself.
What are Quartz Casino's sister sites?
Eighteen are reviewed here on Gambling Commission account 39335: TheOnlineCasino, Mobile Wins, Power Slots, Dream Palace, Royal Swipe, Bluefox Casino, Casimpo, Funky Jackpot, PlayUK, SlotSite.com, 21BetsCasino, Casino Kings, Vegas Mobile Casino, Fruity King, Conquer Casino, Monster Casino, Wombat Casino and JeffBet. 21BetsCasino is the closest in register terms — the only other brand in this round listed Active rather than White Label.
Is Quartz Casino safe and who regulates it?
It operates under Great Britain's strictest gambling permissions: ProgressPlay Limited holds Gambling Commission account 39335 with remote casino, betting and bingo activities, plus Malta Gaming Authority licence MGA/B2C/231/2012. That brings GAMSTOP, deposit and loss limits, reality checks and self-exclusion as licence conditions rather than optional features, and a free route to eCOGRA if a dispute is not resolved. Set against that, the Commission has acted against this licensee twice — a £175,718 settlement in 2022 and a £1,000,000 penalty in 2025 carrying an official warning and a condition requiring a third-party audit.
Does self-exclusion at Quartz Casino cover its sister sites?
Through GAMSTOP, yes — and GAMSTOP goes further, blocking every site licensed in Great Britain rather than only this licence's 115 live domains. Registration is free. The operator's shared terms treat not being registered with GAMSTOP as a warranty the player gives, rather than as an optional extra. Note what self-exclusion does not do: the operator's own sister-site page states that each brand keeps its own account, so a block is not the same thing as a single login across the estate.
