Power Slots is a White Label brand operated by ProgressPlay Limited on Gambling Commission account 39335, one of 115 live domains on the licence, and it opens at a £10 deposit for 50 free spins on Starburst — the lowest entry price of the four brands sharing its page template.
The short answer
ProgressPlay Limited runs 115 brands, and 18 Power Slots sister sites are reviewed here: Casino Kings, Vegas Mobile Casino, Fruity King, Conquer Casino, Monster Casino, Wombat Casino, JeffBet, TheOnlineCasino, Mobile Wins, Dream Palace, Royal Swipe, Bluefox Casino, Casimpo, Funky Jackpot, PlayUK, SlotSite, 21BetsCasino and Quartz Casino. All 18 of these Power Slots Casino sister sites, and Power Slots itself, are operated by ProgressPlay Limited on a single UK Gambling Commission account, 39335.
Compare all 18Pros
- £10 minimum deposit — the lowest of the four brands sharing this template
- 10x wagering, the better of the two rates used on this licence
- 50 free spins tied to Starburst, a game most players already know
Cons
- The page title advertises a "1000 Bonus Pack" against a one-times conversion ceiling
- Three different versions of the same welcome appear in the title, the meta description and the small print
- A €20 version of the offer at 50x wagering sits in the same page as the £10 version at 10x
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, the welcome terms the site links at its own promotion path, its casino promotions page and the register. When budget returns, slot 2 is the one that matters here: the homepage offer tile and the browser title disagree about the size of the welcome, and a single capture settles which number a UK visitor is actually shown. Everything described below was read from Power Slots's own English pages; we would rather show you no picture than the wrong casino's.

How we verified the Power Slots 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 Power Slots shares an operator with these brands
Shared licence numberweight 40%
www.powerslots.com is listed against UK Gambling Commission account 39335, ProgressPlay Limited, with status White Label on the register's 2026-10-29 export. 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 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 www.powerslots.com/promotion/. 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 Power Slots
Power Slots is the cheapest door into a page template that four brands on this licence share, and on price alone it is the one to pick of the four. A £10 minimum deposit returns 50 free spins on Starburst at ten times wagering on the winnings. Dream Palace, which is the same site in different colours, asks £20. Royal Swipe asks £10 as well but caps conversion at three times the bonus rather than one.
The offer needs reading in two places, because the page advertises it twice at very different sizes. The browser title promises a "1000 Bonus Pack + 100 Free Spins"; the meta description promises "50 Free Spins on Starburst"; the small print converts at most one times the bonus amount, or £20 from the free spins. The 50-spin version is the one that matches the terms, and the four-figure version is the one most readers will see first.
The template group is easy to prove rather than assert. Power Slots, Dream Palace, Royal Swipe and Mobile Wins all link their welcome terms at the same platform path, /promotion/wl-uk-welcome-offer-panetcir/ — a slug reading "white label UK welcome offer" that belongs to the operator rather than to any of them — and all four print the identical "JOIN US NOW AND ENJOY OUR WELCOME OFFER" heading above identical 10x small print. The three casino-only ones carry the same identity-verification FAQ down to the phrasing about the middle eight digits of a card and a blanked-out CV2 code.
And one of those siblings vouches for this one by name. Mobile Wins' homepage ranks the top five UK online casinos and lists "Power Slots Casino (Best Slots & Jackpots)" second, without disclosing that both brands sit on Gambling Commission account 39335.
Ownership is printed properly. The footer names ProgressPlay Limited of Soho Office, 3A, Punchbowl Centre, Elia Zammit Street, St. Julians, STJ3154, Malta, Malta company C58305, MGA licence MGA/B2C/231/2012, and Gambling Commission account 39335. Game art and the payment icons come from data.progressplay.net, the same host every brand in this round uses, and the terms name eCOGRA as the free dispute service.
What is thin is the product information. No game count, one named studio, and a claim of "over twenty developers" that nothing on the page supports. Its own bingo section runs a Cash Cubes Room offer on Sundays, which is more than most of its siblings bother with, but the lobby itself is the licence's standard build with the licence's standard gaps.
On trust, treat the licensing as solid and the headline as marketing. Account 39335 has carried remote casino permissions since November 2014 and bingo since August 2024. The Commission fined the licensee £1m in 2025 with an official warning and a licence condition requiring a third-party audit, after a £175,718 settlement in 2022 for overlapping failures. That record belongs to the company behind all nineteen reviewed brands here, not to Power Slots alone.

Licensing & regulation25% weight
80/100
The standard licensing paragraph in full: licensee, Malta company C58305, MGA licence and Gambling Commission account 39335. The register lists the domain White Label and the site does not mention it, which is the one deduction applied across the white labels in this round. (3 sources)
Payouts20% weight
78/100
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
56/100
The gap between the headline and the ceiling is the widest problem here. The page title advertises a "1000 Bonus Pack + 100 Free Spins"; the small print converts at most one times the bonus amount, or £20 from free spins, and the meta description promises a far more modest and more honest 50 free spins on Starburst. Wagering is the licence's better rate at 10x, and the £10 minimum is the lowest of its template group. (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.

Power Slots advertises its welcome offer at three different sizes in three places on the same page. The browser title reads "Power Slots | Mobile Casino | 1000 Bonus Pack + 100 Free Spins"; the meta description reads "Ready, set, go: Start with 50 Free Spins on Starburst"; and the welcome small print sets maximum conversion at one times the bonus amount, or £20 from the free spins, on a £10 minimum deposit at 10x wagering. The 50-spin figure is the one consistent with the terms.

Power Slots states "Min Deposit £10 required" in its welcome small print, where Dream Palace — which shares its page template, its "JOIN US NOW AND ENJOY OUR WELCOME OFFER" heading, its 10x wagering wording and its welcome-terms path at /promotion/wl-uk-welcome-offer-panetcir/ — states "Min Deposit £20 required" for the same construction. Royal Swipe, the third brand on that template, asks £10 but converts at three times the bonus rather than one. Power Slots is therefore the cheapest entry of the template group.

ProgressPlay is a limited liability company registered in Malta (C58305), that is licensed and regulated by Malta Gaming Authority and operates under a License Number of MGA/B2C/231/2012 issued on 16th April, 2013; ProgressPlay Limited is licensed and regulated in Great Britain by the Gambling Commission under account number 39335." The twelfth, Casimpo, carries no such paragraph at all. Quartz Casino carries a decade-old version of it.

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.

All twelve serve their game art, promotion banners and payment-method icons from one host, data.progressplay.net, down to the same file names — data.progressplay.net/content/general/paymentmethods/paypal.png appears on nine of them.

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.

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.

Pros
- £10 minimum deposit — the lowest of the four brands sharing this template

- Full licensing disclosure, including the Malta company number and MGA licence

Cons
- The page title advertises a "1000 Bonus Pack" against a one-times conversion ceiling

- Identical identity-verification wording to three sister brands, down to the phrasing

- A published payment table with limits and fees — no logged-in cashier has been opened
- Any native app
- A published withdrawal time
- Any on-site mention that 114 other brands share its licence
Common complaints about Power Slots
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.

Power Slots Sister Sites — the verdict
Power Slots is the value pick of its own template group, and the reason is simply the entry price: £10 for 50 free spins on Starburst at ten times wagering, where Dream Palace asks £20 for the same construction and Royal Swipe caps conversion three times higher. Ignore the "1000 Bonus Pack" in the browser title — the terms convert at one times the bonus or £20 from the spins, and the site's own meta description is the honest version of its offer. Everything else it shares with eighteen other reviewed brands on account 39335: one licensee, one asset host, one set of terms, one dispute service, and one cap of five casino welcomes across the estate. Its sister Mobile Wins ranks it the second-best casino in the UK without mentioning that they are the same company, which is a fair summary of how much of this licence's marketing to take at face value.

Power Slots sister sites — FAQ
What are Power Slots' sister sites?
Eighteen reviewed here on Gambling Commission account 39335. Its three closest are Dream Palace, Royal Swipe and Mobile Wins, which share its page template and link their welcome terms at the same platform path. The others are TheOnlineCasino, Bluefox Casino, Casimpo, Funky Jackpot, PlayUK, SlotSite.com, 21BetsCasino, Quartz Casino, Casino Kings, Vegas Mobile Casino, Fruity King, Conquer Casino, Monster Casino, Wombat Casino and JeffBet. The licence carries 115 live domains.
Is the Power Slots welcome offer really worth £1,000?
No. The browser title advertises a "1000 Bonus Pack + 100 Free Spins", but the offer's own small print sets maximum conversion at one times the bonus amount, or £20 from the free spins, and the site's meta description describes the offer as 50 free spins on Starburst. The £10 deposit and the 50 spins are the figures that match the terms.
Can I claim a welcome offer at Power Slots and Dream Palace?
Yes — the operator allows a casino welcome at five brands on the licence and says so in the offer: "Limited to 5 brands within the network." The two offers are not equal, though. Power Slots asks £10 and Dream Palace £20 for the same shape of deal on the same template, so claiming at Power Slots first costs less for the same ceiling.
Who operates Power Slots?
ProgressPlay Limited, Malta company C58305 of Soho Office, 3A, Punchbowl Centre, Elia Zammit Street, St. Julians, STJ3154, Malta, holding MGA licence MGA/B2C/231/2012 and Gambling Commission account 39335. The register gives the account's head office as Kolonakiou 26, Office No.18, Agios Athanasios, Limassol, 4103, Cyprus. The domain is listed White Label, so a partner owns the brand while ProgressPlay holds the licence and carries every regulatory obligation.
Is Power Slots 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 Power Slots 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.
