Prime Slots is operated by Skill On Net Limited under UK Gambling Commission account 39326, sharing that licence with 57 other live casino domains, and offers the largest welcome on it — 123 free spins on Thor from a £10 first deposit.
The short answer
There are 5 Prime Slots sister sites: PlayOJO, Simba Games, Megaways Casino, Spin Genie and Slingo. All 5 Prime Slots Casino sister sites are operated by Skill On Net Limited under licence 39326.
Compare all 5Searching for sites like Prime Slots and searching for Prime Slots alternatives are not quite the same question. Every brand on this page shares an operator with Prime Slots — they are Prime Slots sister casinos, not merely platforms like Prime Slots 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 largest welcome on the licence — 123 free spins, against 100 and 50 at its siblings, on identical terms
- Publishes a game count (356) on its own homepage, which only one other brand here does
- Shows its payment logos before registration: Paysafe, PayPal, Trustly, Apple Pay, Mastercard and Visa
Cons
- Wagering applies to the free-spin winnings at 10x, slots only, with a max bet of the lower of 10% or £5
- The 356-game figure is the brand's own claim and has not been independently counted
- The payment logos are a marketing strip, not a verified cashier — limits and fees are unknown
Prime Slots sister sites — the full network
Skill On Net Limited (UK Gambling Commission account 39326) operates 6 UK-facing brands including Prime Slots. The 5 Prime Slots 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.

 | 100 free spins on selected slots with your first depositmin £10 | 71 | Review |

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 Prime Slots Casino sister sites in detail — what it does differently, and who it actually suits.
Simba GamesBest for players who want the offer credited without a code or a claim step
The smallest welcome of the six at 50 free spins, but the least fiddly: they land on Book of Dead and are credited automatically on the first deposit, with no bonus code to enter and nothing to opt into. Its terms share 381 identical sentences with Prime Slots — the tightest clause match on this licence.
- Welcome offer
- 50 free spins on Book of Dead with your first deposit
- Min deposit
- £10
- Wagering
- 10x the free spin winnings, slots only
Megaways CasinoBest for players who specifically want megaways mechanics and an exclusive title
The only brand of the six built around a single game mechanic, and the only one advertising a game nobody else has — Megaloons, which its homepage calls "our first ever exclusive game". Its shelves lead with Megaways titles: Fishin' Frenzy The Big Catch, 5 Lions Megaways, Big Bass Bonanza Megaways and The Dog House Megaways.
- Welcome offer
- 100 free spins on selected slots with your first deposit
- Min deposit
- £10
- Wagering
- 10x the free spin winnings, slots only
Spin GenieBest for players who want the standard package from a long-running name
The most conventional build of the six and the one with the least of its own. It runs the network's shared offer framework and shared legal template with no exclusive game, no published count and no distinguishing mechanic. The register also lists spingenie.co.uk, which redirects to the .com.
- Welcome offer
- 100 free spins on selected slots with your first deposit
- Min deposit
- £10
- Wagering
- 10x the free spin winnings, slots only
SlingoBest for players who came for slingo rather than for slots
The only White Label of the six and the only one selling a game format rather than a casino: 94 Slingo Originals, stated on its own homepage, with Slots, Bingo and Casino as secondary tabs. Its welcome is the only one here needing a bonus code (BMSC100) and the only one with a published start and end date.
- Welcome offer
- 100 free spins on Buffalo Blitz III with your first deposit
- Min deposit
- £10
- Wagering
- 10x the free spin winnings, slots only
PlayOJOBest for players who want no wagering requirements at all
The outlier on its own operator's licence, and deliberately so. No deposit-match welcome offer, no free-spins-on-first-deposit package — a free daily game called OJO's Prize Picker instead, on a brand built around a no-wagering promise. Its lobby is also the broadest here: Slots, Bingo, Roulette, Blackjack, Live Casino, Jackpot and Instants as separate destinations.
- Welcome offer
- No deposit-match welcome offer — a free daily game instead
- Min deposit
- Not applicable to the Prize Picker, which is free to play
- Wagering
- None on winnings — the brand's stated proposition is no wagering
How we verified the Prime Slots sister sites
Most sites simply assert that two casinos are related. These are the signals we actually checked before calling these brands Prime Slots Casino sister sites, and what each one showed. The strongest of them is the shared UK Gambling Commission account 39326, which is a matter of public record rather than inference.
Sister-site verification
How we know Prime Slots shares an operator with these brands
Shared licence numberweight 40%
primeslots.co.uk is listed against UK Gambling Commission account 39326, Skill On Net Limited, with status Active — one of the 40 domains Skill On Net runs as its own brand rather than for a partner. That is the reverse of Jumpman and ProgressPlay, where the white labels vastly outnumber the operator's own. The same account also carries 52 registered trading names.
SourceIdentical T&C clausesweight 25%
Terms compared sentence by sentence: 381 identical sentences with Simba Games and 380 with Prime Casino — the tightest cluster on this licence. The document names Skill on Net Ltd as the contracting party with its Malta company number C50024 and UKGC account 39326.
SourceSame platform fingerprintweight 15%
The welcome offer framework is identical across this licence and only the headline number changes: a £10 minimum deposit, a £0.10 spin value, 10x the free spin winnings, slots only, and a maximum bet of the lower of 10% of the free-spin winnings (min £0.10) or £5. Spin counts observed: 50 at Simba Games, 100 at Slingo, 123 at Prime Slots.
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. Prime Slots displays payment logos on its homepage, but a logo strip is a marketing asset rather than a cashier, and this signal is scored unmatched rather than assumed.
Shared support infrastructureweight 10%
All six publish the same operator, the same Malta company number C50024 and the same Quantum House address in Ta' Xbiex. The two legal templates even disagree slightly on the floor — "Level 5" on one, "Office 1/5297 Level G" on the other — which is the drift you get from two documents maintained separately for one company, not from two companies.

All 5 Prime Slots sister sites reviewed
The Prime Slots Casino sister sites are ordered by how similar each one is to Prime Slots — closest first.
Can you claim a bonus at every Prime Slots Casino sister site?
Each brand advertises its own welcome offer, but the Prime Slots 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? |
|---|---|
| PlayOJO | Unlikely |
| Simba Games | Unlikely |
| Megaways Casino | Unlikely |
| Spin Genie | Unlikely |
| Slingo | Unlikely |
Same company, different deal
Shared ownership does not mean an identical deal. These are the places where the Prime Slots sister sites genuinely beat Prime Slots itself.
Where a sister site beats Prime Slots
PlayOJO — No wagering on winnings
PlayOJO is built on a no-wagering promise. Prime Slots' 123 spins carry 10x wagering on the free-spin winnings and a max bet of the lower of 10% or £5 — standard for this licence, and still a requirement PlayOJO does not impose.
Megaways Casino — A game you cannot play elsewhere
Megaways Casino advertises Megaloons as its first exclusive title. Prime Slots stocks the same mainstream catalogue as its siblings with nothing of its own.
Prime Slots 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 |
|---|---|---|
| Prime Slots (this page) | 123 free spins on Thor with your first deposit | 73 |
| Prime Slots vs Simba Games | 50 free spins on Book of Dead with your first deposit | 70 |
| Prime Slots vs Megaways Casino | 100 free spins on selected slots with your first deposit | 71 |
| Prime Slots vs Spin Genie | 100 free spins on selected slots with your first deposit | 70 |
Prime Slots vs Simba Games
The smallest welcome of the six at 50 free spins, but the least fiddly: they land on Book of Dead and are credited automatically on the first deposit, with no bonus code to enter and nothing to opt into. Its terms share 381 identical sentences with Prime Slots — the tightest clause match on this licence. Prime Slots scores 73 to Simba Games's 70, so the flagship holds up better here. Similarity is 92%, so expect the same cashier and lobby either way.
Prime Slots vs Megaways Casino

Its shelves lead with Megaways titles: Fishin' Frenzy The Big Catch, 5 Lions Megaways, Big Bass Bonanza Megaways and The Dog House Megaways. Prime Slots scores 73 to Megaways Casino's 71, so the flagship holds up better here. Similarity is 85%, so expect the same cashier and lobby either way.
Prime Slots vs Spin Genie
The most conventional build of the six and the one with the least of its own. It runs the network's shared offer framework and shared legal template with no exclusive game, no published count and no distinguishing mechanic. The register also lists spingenie.co.uk, which redirects to the .com. Prime Slots scores 73 to Spin Genie's 70, so the flagship holds up better here.

Sites like Prime Slots: Prime Slots alternatives inside and outside the group
Prime Slots alternatives split into two groups, and conflating them is the mistake most lists make. The 5 brands above are Prime Slots sister casinos — Skill On Net Limited (UK Gambling Commission account 39326) runs every one of them, so the licence, the complaints process and the self-exclusion scope are shared.
Other platforms like Prime Slots — 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 Prime Slots is with the company rather than the product. If you are looking for sites like Prime Slots because you want a fresh welcome bonus, the group brands above are the weaker bet: one licensee generally means one welcome offer.
Which Prime Slots Casino sister site should you pick?
Three different answers, depending on what you are actually optimising for. All 5 Prime Slots 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 Prime Slots: Simba Games, at 92% similarity — same platform, same lobby structure, different welcome offer.
- If you are choosing on trust rather than familiarity: PlayOJO scores highest of the Prime Slots sister sites at 76/100, above Prime Slots's own 73.
- 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 Prime Slots
Prime Slots gives new customers 123 free spins on Thor for a £10 first deposit — the largest welcome of the six brands reviewed on Skill On Net's licence, against 100 at Slingo and 50 at Simba Games. What makes that comparison unusually meaningful is that the rest of the offer does not change. Every brand on this licence runs the same £10 minimum, the same £0.10 spin value, the same 10x wagering on the free-spin winnings, and the same maximum bet of the lower of 10% of those winnings or £5.
On most casino networks a bigger headline hides worse terms. Not here. Jumpman Gaming runs one identical offer across 149 brands; ProgressPlay's brands differ in offer and in terms, with 10x wagering at one and 50x at another. Skill On Net holds the terms constant and varies only the number on the poster — which means on this licence, more spins really is better, and Prime Slots has the most.
The Prime Slots sister sites answer comes from the register. UK Gambling Commission account 39326, held by Skill On Net Limited, carries 60 domains — 40 Active, 18 White Label, 2 Inactive — making 58 live casinos on one licence. primeslots.co.uk is one of the 40 Active entries, meaning Skill On Net runs it as its own brand rather than for a partner. That ratio is the reverse of the other large estates this site models: Jumpman is 18 of its own against 131 white labels, ProgressPlay 20 against 104.
This brand also publishes more than its siblings do. Its homepage states 356 games in one section and 28 in another, and it shows its payment logos before registration — Paysafe, PayPal, Trustly, Apple Pay, Mastercard and Visa. Only Slingo, with its 94 Slingo Originals, matches the first; none of the others match the second. This review reports both as the brand's own claims: nobody here has counted the library or opened a logged-in cashier.
The terms tie it tightly to its siblings. Compared sentence by sentence, Prime Slots shares 381 identical sentences with Simba Games and 380 with Prime Casino — the closest clause match on this licence. The document names Skill on Net Ltd as the contracting party, a company registered in Malta under number C50024 at Quantum House, 75 Abate Rigord Street, Ta'Xbiex, operating under Gambling Commission account 39326. A second template used elsewhere on the same licence cites the Malta Gaming Authority licence MGA/CRP/171/2009/01 instead.
The clause worth reading twice is the wagering. It applies to the winnings from the free spins, not to the spins themselves — so the 123 spins cost nothing, and anything they pay is locked until it has been played through ten times on slots, at a maximum bet of the lower of 10% of those winnings or £5. That combination clears slowly and in small stakes. It is printed under the offer on every brand here, and explained on none of them.
One honest note about the images on this page. Prime Slots captured with its navigation drawer open, and it did so on both the homepage and the promotions page, so it is deterministic rather than a one-off glitch — re-capturing would reproduce it. The offer text and the payment strip are legible around it and the captions say so. On trust, the GB licence brings GAMSTOP, deposit and loss limits, time-outs, reality checks and free ADR access as binding conditions, with a Malta licence alongside; payments and support carry this site's portfolio-wide figures rather than a check of this estate, and the complaint dimension stays at zero because nobody has read the regulatory-actions record for account 39326.

- The wagering applies to the WINNINGS from the free spins, not to the spins themselves — the spins cost nothing, anything they pay is locked until played through ten times.
- Every one of these terms is identical across the brands on this licence. Only the spin count and the game change, which makes comparing them unusually simple: more spins really is better here.

- No bonus code is required; the offer is tied to the first deposit of at least £10.
Games at Prime Slots
One of only two brands on this licence to publish a figure. Its homepage states 356 games in one section and 28 in another — reported here as the brand's own claims, not an independent count. Observed from a GB capture on 5 September 2026, titles on the shelves included Fins of Fortune, Triple Seven (Games of Crazy 7), DJ Dog, Fort Knox Wolf Run, Wild Tomb and Lucky 1000 Hold & Win. Navigation runs Home, Promotions, Slots, Scratch Cards and Casino. Providers named across the estate's pages include NetEnt, Blueprint, Red Tiger, Eyecon, Games Global, Light & Wonder and Yggdrasil.

Each provider above is printed beneath its own game tile in the lobby, so these are read from the site rather than inferred.
Prime Slots organises its lobby into 3 categories: Slots, Scratch Cards, Casino. 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 39326, Skill On Net Limited. primeslots.co.uk carries register status Active — one of the 40 domains the operator runs as its own brand, with no commercial partner between the player and the licence holder. The operator publishes its Malta company number C50024, its Quantum House address and MGA licence MGA/CRP/171/2009/01 alongside the UKGC account. (2 sources)
Payouts20% weight
78/100
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)
Bonus fairness20% weight

Prime Slots pros and cons
Pros
- The largest welcome on the licence — 123 free spins, against 100 and 50 at its siblings, on identical terms
- Publishes a game count (356) on its own homepage, which only one other brand here does
- Shows its payment logos before registration: Paysafe, PayPal, Trustly, Apple Pay, Mastercard and Visa
- Register status Active — Skill On Net's own brand, with no partner in between
- Scratch Cards as a separate destination, which most of its siblings do not offer
- Publishes the operator's Malta company number C50024 and UKGC account 39326 in its own terms
Cons
- Wagering applies to the free-spin winnings at 10x, slots only, with a max bet of the lower of 10% or £5
- The 356-game figure is the brand's own claim and has not been independently counted
- The payment logos are a marketing strip, not a verified cashier — limits and fees are unknown
- Nothing on the site names the 57 other live casinos on its licence
- Its captures show a navigation drawer open, obscuring part of the hero
- The complaint record for account 39326 has not been reviewed, so that dimension is unscored
What Prime Slots lacks
- A verified payment-method table with limits and fees — the homepage strip is a claim, not an opened cashier
- A native mobile app; the mobile experience is the responsive site
- Any stated position on whether a welcome offer can be claimed at a sister brand
- A provider list attached to the game count
Common complaints about Prime Slots
Themes drawn from public review platforms and forums. These are paraphrased summaries of recurring patterns, not quotes, and they describe what players report rather than what we have verified.
The wagering applies to the free-spin winnings, not the spins
commonEvery offer on this licence sets wagering at 10x the winnings FROM the free spins, slots only — so the spins themselves cost nothing but anything they produce is locked until it has been played through ten times. Combined with a maximum bet of the lower of 10% of those winnings or £5, a good run is cleared slowly and in small stakes. All of it is printed under the offer; none of it is explained.
Homepage small print captured from a GB connection, 5 September 2026
Nothing states whether a second welcome offer works
commonFifty-eight live casinos sit on this one licence and not one of them says whether a player who has claimed at a sister brand can claim again. ProgressPlay, a comparable operator, publishes a five-brand cap in its own small print. Here the reader is left to guess, and the safe assumption on any shared licence is one offer per customer.

Names on the door that are not the operator
occasionalGenting Casino and Slingo both run on this licence as white labels. Genting's own Gambling Commission account, 537, holds no domains at all — it licenses the land-based estate. A player who chooses Genting online for the reputation of the buildings is contracting with a platform operator instead, and only the register says so.

Prime Slots Sister Sites — the verdict
Prime Slots is the pick of Skill On Net's licence if you want a welcome offer, for a simple reason: it gives the most spins on terms nobody else improves on. 123 against Slingo's 100 and Simba Games' 50, with the same £10 minimum, the same 10x wagering and the same max bet across all three. It also tells you more than its siblings — a game count on the homepage and its payment methods before you register. The Prime Slots sister sites list runs to 57 other live domains on Gambling Commission account 39326, and the only thing that changes between most of them is the number on the poster.
On the network question specifically: the 5 Prime Slots Casino sister sites rate confirmed on our fingerprint at 90/100, and the evidence behind that is set out above rather than asserted. Treat them as one operator wearing 6 front doors.
Prime Slots sister sites — FAQ
How many Prime Slots sister sites are there?
57 other live domains share its Gambling Commission licence — account 39326, Skill On Net Limited — for 58 live in total, plus 2 marked Inactive. PlayOJO, Simba Games, Megaways Casino, Spin Genie and Slingo are five of them, reviewed here in full. Genting Casino runs on the same account as a white label.
Is Prime Slots' 123 free spins offer better than its sister sites'?
Yes, and unusually you can say that plainly. Every brand on this licence runs the same £10 minimum deposit, £0.10 spin value, 10x wagering on the free-spin winnings and maximum bet of the lower of 10% or £5. Only the spin count and the game change — 123 here, 100 at Slingo, 50 at Simba Games — so nothing behind the headline offsets the bigger number.
Does Prime Slots really have 356 games?
That is the figure on its own homepage, reported here as the brand's claim rather than a verified count, because nobody here has counted them. It is worth noting because only one other brand of the six reviewed on this licence publishes a library figure at all — Slingo, with 94 Slingo Originals.
Who owns Prime Slots?
Skill on Net Ltd, a company registered in Malta under number C50024 with its business address at Quantum House, 75 Abate Rigord Street, Ta' Xbiex, operating under UK Gambling Commission account 39326 and Malta Gaming Authority licence MGA/CRP/171/2009/01. The site publishes that in its own terms, and the register lists primeslots.co.uk against that account with status Active — one of the 40 domains Skill On Net runs as its own brand.
Does Prime Slots share an account with its sister sites?
Not established, and this review will not guess. All 58 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. Unlike ProgressPlay, which publishes a five-brand welcome cap implying a shared bonus ledger, nothing on this licence states a cross-brand position at all. What is certain is that self-exclusion reaches every brand through GAMSTOP, a binding condition of the GB licence.
