Casino Kings is operated by ProgressPlay Limited under UK Gambling Commission account 39335, a licence carrying 116 live domains, the second-largest single-licence estate in Great Britain, and its own welcome terms cap the offer at five brands within that network.
The short answer
ProgressPlay Limited runs 116 brands, and 6 Casino Kings sister sites are reviewed here: Vegas Mobile Casino, Fruity King, Conquer Casino, Monster Casino, Wombat Casino and JeffBet. All 6 of these Casino Kings Casino sister sites, and Casino Kings itself, are operated by ProgressPlay Limited on a single UK Gambling Commission account, 39335.
Compare all 6Pros
- The simplest welcome offer on the licence — £20 for 100 free spins, with no percentage match to work out
- 10x wagering, a fifth of what Monster and Conquer Casino ask on the same licence
- £30 maximum conversion from free spins, the most generous ceiling of the six reviewed here
Cons
- The network is disclosed but never named — finding your sister sites means reading 191 rows on a government register
- No published game count or provider total, so the library cannot be checked before registering
- Free-spin winnings convert to cash only up to £30, whatever the spins actually pay

Vegas Mobile CasinoBest for players who want the biggest headline package and a published game count
The only one of the six that publishes a library figure on its own homepage: 5,586+ games, alongside 24/7 live tables and a £10 minimum deposit, in a stats bar under the hero. It also runs the largest headline — up to £1,000 plus 100 free spins — and prints ProgressPlay's Malta registered address in full in its terms.

Fruity KingBest for uk players who want the offer quoted in pounds and the terms shown up front
The only brand of the six observed to localise its welcome offer properly: its HTML carries separate geo-gb and geo-row blocks and it serves a UK visitor 100% up to £100 with 50 free spins in sterling. Its 10x wagering is the joint-lowest here, against 50x on Monster and Conquer, and a left sidebar puts Scratch Cards, Roulette and Blackjack one click from the homepage.

Conquer CasinoBest for players outside the uk who want a region-switching lobby
Carries an explicit region selector offering United Kingdom, Canada, New Zealand and Japan — the only one of the six to do so — but quotes its welcome bonus in €/$ even to a UK visitor, and runs 50x wagering. It has no /slots page at all; the games live at /all-games/.

JeffBetBest for players who want a sportsbook, casino and bingo on one progressplay account
A sportsbook first. Its bet £10, get a £30 free bet counts as the single sports welcome this licence allows, and it is the brand the Advertising Standards Authority ruled against in May 2024 over how that network rule was shown. Its casino welcome has Fruity King's shape, 100% up to £100 plus 50 free spins at 10x, on Rainbow Riches Megaways instead.

- Casino: 10x the bonus within 30 days and 10x free-spin winnings within 7 days. Sports: 1x the free bet winnings
Monster CasinoBest for players who want casino and sports under one account with a big headline number
The largest advertised package on the licence at up to €/$1,000 plus 250 free spins — and the currency is the catch, because that figure is served unchanged to British visitors. Its lobby is the lightest-looking of the six, with a casino/sports toggle in the header and its own separate bingo section.

Wombat CasinoBest for players who want the shortest, plainest welcome offer on the licence
The outlier. Its terms sit on a different legal template from the other five — 135 to 139 shared sentences against their 260 to 287 — its offers live at /bonuses/ rather than /promotions/, and its welcome is a bare 50 free spins with no deposit match at all. That simplicity comes with the tightest cap here: £5 maximum conversion from the free spins.

3 of 5 signals matched, for a fingerprint of 75/100 (confirmed). How the signals are weighted.

How we know Casino Kings shares an operator with these brands
Shared licence numberweight 40%
casinokings.com is listed against UK Gambling Commission account 39335, ProgressPlay Limited, with status White Label — the register's own term for a site the licensee operates on a third party's behalf. The brand belongs to a partner; the licence, the player's contract and every regulatory obligation belong to ProgressPlay. The same account carries 116 live domains.
SourceIdentical T&C clausesweight 25%
Terms compared sentence by sentence against the other brands on this licence: 260–287 identical sentences pairwise, in documents of roughly 12,300 words. The operator is named as the contracting party throughout, with its Malta company number and MGA licence.
SourceSame platform fingerprintweight 15%not established
NOT matched on appearance, which is the opposite of what this signal usually shows and the reason this network scores differently from Jumpman. The six brands share no skin, no navigation pattern and no URL scheme: /promotions/ on four, /bonuses/ on Wombat, /online-slots/ on two, /all-games/ on Conquer, which has no /slots page. Common ownership here is proved by the register and the terms, not by the interface.
SourceShared payment processorweight 10%not established
Not established. No logged-in cashier has been opened on any brand on this licence, so the processors behind the deposit flow are unverified. One licensee normally means one payment stack, but normally is not evidence, and this signal is scored unmatched rather than assumed.
Shared support infrastructureweight 10%
The operator states the relationship itself. The welcome small print ends "Limited to 5 brands within the network.", with "network" linked to the Gambling Commission's domain list for account 39335 — a shared bonus ledger across brands, disclosed by the operator and citing the regulator. Eight of ten brands fetched carry that link.

Where a sister site beats Casino Kings
Vegas Mobile Casino — Headline package and a published library size
Vegas Mobile advertises up to £1,000 plus 100 free spins and prints 5,586+ games in a stats bar on its own homepage. Casino Kings offers a flat £20-for-100-spins and publishes no game count at all.
Fruity King — Wagering on the deposit match
Fruity King runs 10x wagering on its 100% match. Casino Kings has no deposit match to compare, so a player who wants a percentage bonus rather than spins is better served next door.

About Casino Kings
Casino Kings is the most complete product on ProgressPlay's licence, and the easiest of its sisters to explain. The top navigation carries Casino, Live Casino, Slots, Sports, Bingo, Jackpots, Scratchcards and News as separate destinations, which is a wider spread than any of the five other brands reviewed here manage — and its welcome offer is the one that needs no arithmetic: deposit £20, get 100 free spins. No percentage match, no tiered package, no multi-deposit structure.
The Casino Kings sister sites question has an unusually direct answer, because the operator supplies it. The small print under that offer ends with the sentence "Limited to 5 brands within the network", and the word network is a hyperlink pointing at the Gambling Commission's public register page for account 39335 — the list of every domain ProgressPlay Limited operates. The operator is telling players a network exists, capping the welcome offer across it, and citing the regulator for its membership. Nothing else on this site does that.
On the register's export of 17 September 2026 that page lists 191 domain rows against ProgressPlay: 20 marked Active, 96 marked White Label and 75 Inactive. So 116 live sites sit on one licence, the second-largest single-licence estate in Great Britain, behind only Jumpman Gaming's. casinokings.com is one of the White Label entries, meaning a commercial partner owns the brand while ProgressPlay holds the licence, the player's contract and every regulatory obligation.
Where this network differs sharply from Jumpman's is that the brands are genuinely different products. Jumpman runs its whole estate as one skin with one offer repeated word for word. Here, no two of the six brands reviewed share a layout, an offer, a conversion cap or even a URL scheme. Casino Kings runs a horizontal nav bar on near-black; Fruity King a left sidebar on light blue; Vegas Mobile a dark icon rail. Casino Kings' games sit at /online-slots/, Conquer's at /all-games/, Wombat's offers at /bonuses/. The shared licence is proved by the register and the terms, not by the interface.
The terms do carry the family resemblance. Compared sentence by sentence against Vegas Mobile, Fruity King and Conquer Casino, this brand's terms share between 260 and 287 identical sentences in documents of roughly 12,300 words — the same legal template with the brand name swapped. Wombat, on the same licence, shares only 135 to 139, which is how we know ProgressPlay runs at least two templates rather than one.
On the offer itself, Casino Kings is the pick of the six for anyone who reads terms. Its 10x wagering matches the lowest on the licence and is a fifth of what Monster and Conquer ask. Its £30 maximum conversion from free spins is the most generous ceiling here — against £20 at Fruity King and Vegas Mobile and just £5 at Wombat. And because the offer is spins rather than a match, there is no bonus balance to clear before a withdrawal becomes possible.
The corporate picture is more transparent than most. The terms publish ProgressPlay's Malta company number (C58305), its registered address at Soho Office, 3A Punchbowl Centre, Elia Zammit Street, St Julians, its MGA licence MGA/B2C/231/2012 issued 16 April 2013, and the UKGC account number that matches the register exactly. Payments and support carry a portfolio-level result rather than a timing recorded for this brand specifically, and that is flagged rather than hidden. The regulatory record for account 39335, read on 17 September 2026, is not clean: a £175,718 settlement in 2022 and a £1m penalty with a warning and a mandatory audit in 2025. The complaint dimension is scored on it.

That is more disclosure than any other operator on this site provides — and it still requires a player to click through to a government database and read a list of 191 domains to learn which casinos they have already used up their allowance on. No brand names a single sibling.

Wagering requirements vary fivefold across one licence
commonFruity King, Vegas Mobile and Casino Kings run 10x wagering. Monster and Conquer Casino run 50x on the same operator's licence. A player who learns the terms at one brand and assumes they carry across — which is exactly what a shared licence invites — can land on an offer five times harder to clear.

Maximum conversion caps what a win is worth, and differs per brand
commonEvery offer here caps how much bonus or free-spin winnings can become withdrawable cash: £5 at Wombat, £20 at Fruity King and Vegas Mobile, £30 at Casino Kings and Monster. The figure sits in grey small print under the sign-up button and is the term most likely to surprise someone who has just had a good run on the spins.

A large estate of retired brands
occasional75 domains on this licence carry Inactive status, including Jackpot Paradise, Goldman Casino, Dazzle Casino, Ace Lucky and Grandmaster Jack, and eight White Labels were switched off between the register's exports of 19 August and 17 September 2026. People still search for several of them as live sites. The register gives no dates, so when each closed is not something this page claims.

The licensee has been sanctioned twice for the same kinds of failure
occasionalThe Gambling Commission announced a £175,718 settlement with ProgressPlay in May 2022 for social-responsibility and anti-money-laundering failures. In August 2025 it announced a £1m penalty, an official warning and a licence condition requiring a third-party audit, for anti-money-laundering and customer-interaction failings between August 2021 and August 2024, and called it the second time. Both are findings about the licensee, which runs every brand on this account.

Casino Kings Sister Sites — the verdict
Casino Kings is the brand to pick on this licence if you read terms before you deposit. It has the lowest wagering, the highest free-spins conversion ceiling, the widest product range and the least complicated offer of the six reviewed — and its small print does something almost no operator does, telling you outright that a network exists and capping your welcome offers at five brands within it. What it will not do is name those brands, so the Casino Kings sister sites list still has to be reconstructed from the Gambling Commission's register. That is exactly what this page is for.

Casino Kings sister sites — FAQ
How many Casino Kings sister sites are there?
116 live domains share its Gambling Commission licence — account 39335, ProgressPlay Limited — of which Casino Kings is one. The register's export of 17 September 2026 lists 191 rows: 20 Active, 96 White Label and 75 Inactive. Six others are reviewed here in full: Vegas Mobile Casino, Fruity King, Conquer Casino, Monster Casino, Wombat Casino and JeffBet.
Can I claim a welcome bonus at every Casino Kings sister site?
Up to five of them, according to the operator. The welcome small print states "Limited to 5 brands within the network", with network linked to the Gambling Commission's domain list for account 39335. That is a published rule rather than an inference — on most casino networks this question can only be answered by guessing. It has not been tested with real accounts, and because the offers differ in size and conversion cap, five claims are not five equal claims.
Is Casino Kings the same company as Vegas Mobile Casino?
Both are operated by ProgressPlay Limited on UKGC account 39335, and both say so in their own terms alongside the operator's Malta company number C58305 and MGA licence MGA/B2C/231/2012. Their terms share between 260 and 287 identical sentences. The sites look nothing alike, which is normal on this licence — ProgressPlay's brands differ far more from one another than Jumpman Gaming's do.
Is Casino Kings safe to play at?
It runs on a full UK Gambling Commission licence through ProgressPlay Limited, which makes GAMSTOP integration, deposit and loss limits, time-outs, reality checks and free access to an approved dispute-resolution body binding conditions rather than choices. ProgressPlay also holds a Malta Gaming Authority licence. The licensee's record is not clean: the Gambling Commission announced a £175,718 settlement in May 2022 and, in August 2025, a £1m penalty with a warning and a mandatory third-party audit for anti-money-laundering and customer-interaction failings.
Does Casino Kings share an account with its sister sites?
Not established, and this review will not guess. All 116 live domains sit on one licensee, which makes a shared wallet and a shared set of verification documents plausible — but nobody has logged in and tested it. What the operator does state is that the welcome offer is capped at five brands across the network, which means at minimum a shared bonus ledger. Self-exclusion reaches every brand through GAMSTOP, a binding condition of the GB licence.
