Casino Kings is operated by ProgressPlay Limited under UK Gambling Commission account 39335 — a licence carrying 124 live casino domains, the second-largest sister-site network in Great Britain — and its own welcome terms cap the offer at five brands within that network.
The short answer
There are 5 Casino Kings sister sites: Vegas Mobile Casino, Fruity King, Conquer Casino, Monster Casino and Wombat Casino. All 5 Casino Kings Casino sister sites are operated by ProgressPlay Limited under licence 39335.
Compare all 5Searching for sites like Casino Kings and searching for Casino Kings alternatives are not quite the same question. Every brand on this page shares an operator with Casino Kings — they are Casino Kings sister casinos, not merely platforms like Casino Kings that happen to look similar. That distinction decides whether one welcome bonus, one self-exclusion and one KYC check cover all of them.
Pros
- 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
Casino Kings sister sites — the full network
ProgressPlay Limited (UK Gambling Commission account 39335) operates 6 UK-facing brands including Casino Kings. The 5 Casino Kings Casino sister sites below share that licence, and in most cases the same bonus mechanics — what changes between them is the price, the size of the offer and the product mix.

Similarity estimates how much of the same experience you get — shared licence, platform and bonus mechanics, less any product differences. A high similarity score is not an endorsement: a close copy of a weak casino is still a weak casino.
Each of the 5 Casino Kings Casino sister sites in detail — what it does differently, and who it actually suits.
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.
- Welcome offer
- Welcome package up to £1,000 plus 100 free spins on Buffalo Blitz and Starburst
- Min deposit
- £10
- Wagering
- 10x the bonus money within 30 days; 10x free-spin winnings within 7 days
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.
- Welcome offer
- 100% welcome bonus up to £100 plus 50 free spins on Big Bass Bonanza
- Min deposit
- Not stated on the homepage tile — read the full terms before depositing
- Wagering
- 10x the bonus money within 30 days; 10x free-spin winnings within 7 days
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/.
- Welcome offer
- 100% welcome bonus up to €/$100 plus 10 free spins on Starburst
- Min deposit
- Not stated on the homepage tile — read the full terms before depositing
- Wagering
- 50x the bonus money within 30 days; 50x free-spin winnings within 7 days
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.
- Welcome offer
- Welcome package up to €/$1,000 plus 250 free spins on Starburst
- Min deposit
- £/€/$10, per the homepage small print
- Wagering
- 50x the bonus money within 30 days; 50x free-spin winnings within 7 days
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.
- Welcome offer
- 50 free spins on Bigger Bass Splash

How we verified the Casino Kings sister sites
Most sites simply assert that two casinos are related. These are the signals we actually checked before calling these brands Casino Kings Casino sister sites, and what each one showed. The strongest of them is the shared UK Gambling Commission account 39335, which is a matter of public record rather than inference.
Sister-site verification
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 124 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.

All 5 Casino Kings sister sites reviewed
The Casino Kings Casino sister sites are ordered by how similar each one is to Casino Kings — closest first.
Can you claim a bonus at every Casino Kings Casino sister site?
Each brand advertises its own welcome offer, but the Casino Kings Casino sister sites sit behind one licensee and one fraud-detection layer. Assume one welcome across the group unless a brand states otherwise.
| Sister site | Separate welcome? |
|---|---|
| Vegas Mobile Casino | Likely |
| Fruity King | Likely |
| Conquer Casino | Likely |
| Monster Casino | Likely |
| Wombat Casino | Likely |
Same company, different deal
Shared ownership does not mean an identical deal. These are the places where the Casino Kings sister sites genuinely beat Casino Kings itself.
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.
Casino Kings vs its sister sites, head to head
Same operator, same licence, same platform — so the comparison comes down to the offer and the product mix. Each pairing below is scored on the same rubric, which is what makes them comparable at all.
| Matchup | Welcome offer | Trust |
|---|---|---|
| Casino Kings (this page) | Deposit £20 and get 100 free spins | 71 |
| Casino Kings vs Vegas Mobile Casino | Welcome package up to £1,000 plus 100 free spins on Buffalo Blitz and Starburst | 71 |
| Casino Kings vs Fruity King | 100% welcome bonus up to £100 plus 50 free spins on Big Bass Bonanza | 72 |
| Casino Kings vs Conquer Casino | 100% welcome bonus up to €/$100 plus 10 free spins on Starburst | 66 |
Casino Kings vs Vegas Mobile Casino
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. Both score 71, so the choice is product fit rather than trust. Similarity is 88%, so expect the same cashier and lobby either way.

Casino Kings vs Conquer Casino
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.

Similarity is 84%, so expect the same cashier and lobby either way.
Sites like Casino Kings: Casino Kings alternatives inside and outside the group
Casino Kings alternatives split into two groups, and conflating them is the mistake most lists make. The 5 brands above are Casino Kings sister casinos — ProgressPlay Limited (UK Gambling Commission account 39335) runs every one of them, so the licence, the complaints process and the self-exclusion scope are shared.
Other platforms like Casino Kings — unrelated casinos with a comparable lobby or a similar offer — are a different proposition entirely. They give you a genuinely separate operator, which matters if your complaint with Casino Kings is with the company rather than the product. If you are looking for sites like Casino Kings because you want a fresh welcome bonus, the group brands above are the weaker bet: one licensee generally means one welcome offer.
Which Casino Kings Casino sister site should you pick?
Three different answers, depending on what you are actually optimising for. All 5 Casino Kings Casino sister sites clear the same licensing bar, so this is a question of fit rather than safety.
- If you want the closest thing to Casino Kings: Vegas Mobile Casino, at 88% similarity — same platform, same lobby structure, different welcome offer.
- If you are choosing on trust rather than familiarity: Fruity King scores highest of the Casino Kings sister sites at 72/100, above Casino Kings's own 71.
- If you already have an account here: check the bonus table above before opening a second one. A separate welcome offer at another brand in this group is the exception, not the rule.
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.
That register page lists 191 domain rows against ProgressPlay: 20 marked Active, 104 marked White Label and 67 Inactive. So 124 live casinos sit on one licence, making this the second-largest sister-site network in Great Britain, behind only Jumpman Gaming's 149. 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 149 casinos 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 this site's portfolio-wide figures rather than a check of this estate specifically — that is flagged rather than hidden, and the complaint dimension stays at zero because nobody has read the regulatory-actions record for account 39335.

Each provider above is printed beneath its own game tile in the lobby, so these are read from the site rather than inferred.
Casino Kings organises its lobby into 6 categories: Slots, Live Casino, Sports, Bingo, Jackpots, Scratchcards. That rail is identical across every brand in the network — the same categories in the same order — which is one of the clearer signals that they run on shared infrastructure rather than merely sharing an owner.

UK Gambling Commission account 39335, ProgressPlay Limited. casinokings.com carries register status White Label — a partner owns the brand, the licensee carries every obligation. The operator publishes its Malta company number C58305, its registered address and MGA licence MGA/B2C/231/2012 alongside the UKGC account, which is more corporate detail than most operators on this site disclose.

Payouts20% weight

Withdrawals cleared in 5 to 15 minutes when checked by our own team in August 2026. That is fast by any standard in this market — for comparison, the fastest published windows elsewhere on this site are BetMGM's and Pink Casino's at one to three days. Not scored higher because speed was the only input recorded: no logged-in cashier method list, no minimum, maximum or fee schedule, and no note of what identity verification asked for or at what point. The figure is a portfolio-level result rather than a per-brand timing, so every brand it covers carries the same score. (1 source)

Casino Kings pros and cons
Pros
- 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
- The widest product spread: casino, live casino, slots, sports, bingo, jackpots and scratchcards in one lobby
- The operator's Malta company number, registered address, MGA licence and UKGC account are all published in the terms
- The five-brand network cap is disclosed on the homepage, with a link to the regulator's own list
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
- Skrill and Neteller deposits are excluded from the welcome offer
- The complaint record for account 39335 has not been reviewed, so that dimension is unscored
- Payout speed and support carry this site's portfolio default rather than a check of this estate
What Casino Kings lacks
- A published payment-method table — no logged-in cashier has been opened on this brand
- A native mobile app; the mobile experience is the responsive site
- A stated total game count or provider list
- Any on-site naming of the 123 other live casinos on its licence

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
occasionalSixty-seven domains on this licence carry Inactive status, including Jackpot Paradise, Goldman Casino, Dazzle Casino, Ace Lucky and Grandmaster Jack. 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.

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.
On the network question specifically: the 5 Casino Kings Casino sister sites rate confirmed on our fingerprint at 75/100, and the evidence behind that is set out above rather than asserted. Treat them as one operator wearing 6 front doors.
Casino Kings sister sites — FAQ
How many Casino Kings sister sites are there?
124 live domains share its Gambling Commission licence — account 39335, ProgressPlay Limited — of which Casino Kings is one. The register lists 191 rows in total: 20 Active, 104 White Label and 67 Inactive. Five others are reviewed here in full: Vegas Mobile Casino, Fruity King, Conquer Casino, Monster Casino and Wombat Casino.
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. One caveat this review states openly: the regulatory-actions record for account 39335 has not been read here, so the complaint dimension is scored zero — meaning unmeasured, not clean.
Does Casino Kings share an account with its sister sites?
Not established, and this review will not guess. All 124 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.
