Sunny Casino Sister Sites: Who Runs Them and Where to Go Next
Casinos like Sunny Casino include Mr Play, Slots Cafe, Maria Casino, Casino British, Quid Slots and Casino Kings, alongside a broad spread of white-label skins on the same platform. What ties them together is the operator: all are run by ProgressPlay Limited under a single UK Gambling Commission licence (account 39335), with a Malta Gaming Authority licence for non-UK players. Sunny Casino’s own pitch is its bright, beach-themed lobby and a heavy lean on instant wins and scratchcards next to the slots, though the engine beneath is shared across the network.

Sunny Casino Sister Sites in Full
Reviewed by Emma JenkinsPublished: Jul 2022 · Last updated: June 2026
One thing to pin down first. Sunny Casino’s own footer points to a “sister site” (Casino Kings), but it doesn’t publish the wider family, and ProgressPlay’s network is mostly white-label. So this page uses the common UK search meaning of sister site: any brand ProgressPlay operates on the same UKGC licence (39335). That connects Sunny Casino to a long list of skins sharing its cashier, verification and game lobby, even where the names look nothing alike.
Best Sunny Casino Sister Sites at a Glance
- Best overall: Mr Play, the most recognisable and best-supported ProgressPlay brand.
- Best for instant wins: Prime Scratch Cards, a scratchcard specialist on the network.
- Best for slots range: Slots Cafe, a large multi-provider library.
- Best for a British feel: Casino British, a UK-themed skin.
- Best low-stakes option: Quid Slots, pitched at small-stakes players.
- Best named sister: Casino Kings, the brand Sunny Casino itself points to.
Sunny Casino Sister Sites Compared
| Sister site | Status | UKGC licence | Best for | Welcome offer (always check current terms) | Compared to Sunny Casino |
|---|---|---|---|---|---|
| Mr Play | Open | Yes (#39335) | All-round | Match plus spins | Bigger brand, sharper support |
| Prime Scratch Cards | Open | Yes (#39335) | Instant wins | Match plus spins | Scratchcard focus |
| Slots Cafe | Open | Yes (#39335) | Slots range | Match plus spins | Larger library, same platform |
| Casino British | Open | Yes (#39335) | UK theme | Match plus spins | British styling, same backend |
| Quid Slots | Open | Yes (#39335) | Low stakes | Match plus spins | Small-stakes angle |
| Casino Kings | Open | Yes (#39335) | Named sister | Match plus spins | Closest like-for-like skin |
Mr Play
Operated by ProgressPlay on UKGC licence 39335, Mr Play is the most recognisable brand on the platform, with a slots-and-sports lean and a more confident, better-supported front end. It uses the same 2,000-plus game library and the same cashier as Sunny Casino. Versus Sunny, it’s the step up if you want the same network behind a bigger, more trusted name.
Prime Scratch Cards
Prime Scratch Cards is the network’s instant-win specialist, scratchcards and quick-play games front and centre, on the same ProgressPlay licence and payments. If the part of Sunny Casino you enjoy is the scratchcard and instant-win corner, this brand puts it first. The slots and tables are still there underneath.
Slots Cafe
Slots Cafe leans on the breadth of the ProgressPlay slots catalogue across NetEnt, Pragmatic Play, Microgaming and more, on the same UK licence. Banking and support mirror Sunny Casino. Compared to Sunny it’s a sideways move with a fuller slot grid and a slots-first home page rather than a scratchcard lean.
Casino British
Casino British wraps the ProgressPlay platform in UK-flag styling and British-themed slots, on the same licence 39335 and cashier. It’s a cosmetic difference from Sunny Casino more than a functional one, useful if you want a homegrown feel without leaving the network.
Quid Slots
Quid Slots pitches itself at small-stakes players, low minimums and pound-friendly play, on the same ProgressPlay platform and licence. The games and banking are the network standard. Against Sunny Casino it’s a budget-minded reskin rather than a different casino.
Casino Kings
Casino Kings is the brand Sunny Casino names directly as its sister, and it’s the closest like-for-like: same UKGC licence, same lobby, same support hours and the same offer template now capped at 10x wagering under UK rules. The royal theme is the main change. Treat it as a fresh welcome offer on identical software rather than a new experience.
The Complete ProgressPlay Network List
ProgressPlay’s line-up is large, and the brand counts you see quoted elsewhere fold in every live and dormant skin, so any single number is a snapshot rather than a fixed roster. Broadly it splits into:
- Flagship and owned brands: Mr Play, Slots Cafe and similar names ProgressPlay promotes directly.
- White-label skins: third-party-branded casinos on the platform under the same licence, including Sunny Casino, Casino British, Quid Slots, Casino Kings and Maria Casino.
- Instant-win brands: Prime Scratch Cards and a few others built around scratchcards and quick games.
Confirm any of them by looking ProgressPlay up on the UK Gambling Commission register and matching the licence number in the footer. A different licence holder means it isn’t a true sister.

Are These Official Sunny Casino Sister Sites?
Three groups get blurred. There’s no official “Sunny” brand family, so that bucket is empty, and the similarly named PlaySunny is a different operator (Dazzletag), not a ProgressPlay sister. There’s the same-operator network, the ProgressPlay brands on licence 39335 above, which is what we mean by a sister site, and Sunny Casino itself names Casino Kings among them. And there are unrelated casinos that merely share some game studios, which isn’t an ownership link. Sharing a slot or a payment processor doesn’t make two sites sisters.
Sunny Casino Review
Operator details last reviewed: June 2026 (last updated 8 June 2026)
Updated June: confirmed ProgressPlay as the operator, replaced the stale sister list with verified network brands and removed old pre-cap wagering figures.
Sunny Casino runs a bright, beach-flavoured lobby on the ProgressPlay platform. The hook is cheerful presentation and a strong instant-win corner, scratchcards and quick games sit alongside the slots, rather than the dark, slots-only feel of some sisters. Under the surface, though, it’s standard ProgressPlay.
Welcome Offer and Promotions
The welcome offer is a first-deposit match plus free spins on a featured slot, with a £10 or £20 qualifying deposit depending on the live deal. ProgressPlay’s older terms quoted high wagering (you’ll still see “50x” or “65x” on stale affiliate listings), but under the UK rules in force since January 2026 bonus wagering is capped at 10x on UKGC sites, so those old multiples no longer apply to UK players. Bonus conversion is capped relative to your deposits, which is normal for the network, so check the current offer page before opting in.
Games and Providers
You get the platform-standard library of 2,000-plus titles from NetEnt, Pragmatic Play, Microgaming, Play’n GO and others, plus a live casino and a noticeably bigger scratchcard and instant-win selection than most sisters. Slots still dominate, but the instant-win lean is the genuine point of difference here.
Payments and Withdrawals
Debit cards, PayPal and Paysafecard are the usual options, min deposit £10. Payout speed is average for the group, e-wallets quickest, cards slower. As across ProgressPlay, player funds carry the UKGC “Not protected” segregation status, so balances aren’t ring-fenced to the highest tier if the operator fails, and first-withdrawal KYC is mandatory.
Support and Responsible Gambling
Live chat and email are the support routes, with chat the faster of the two. As a UKGC brand, Sunny Casino is covered by GamStop and offers deposit limits, time-outs and self-exclusion. GamCare and BeGambleAware are signposted for support. For fair context, ProgressPlay has twice been sanctioned by the UKGC over AML and social-responsibility failings, which is worth weighing when judging the operator.
Mobile
No app is needed, the browser site is built for phones and the bright lobby actually reads well on a small screen. It’s a straightforward mobile experience rather than a standout one.
How It Compares to Its Sister Sites
Strip the beach theme away and Sunny Casino, Casino Kings and Casino British are nearly the same casino. Mr Play is the bigger, better-supported brand, Slots Cafe has the fuller slot grid, and Prime Scratch Cards is the one to pick if instant wins are your thing. Switching mostly changes the wallpaper and the welcome offer.

Frequently Asked Questions
Who owns Sunny Casino?
Sunny Casino (sunnycasino.com) is operated by ProgressPlay Limited, a Malta-registered company (C58305) licensed by the UK Gambling Commission under account 39335 and by the Malta Gaming Authority.
Does Sunny Casino have sister sites?
Yes. It shares the ProgressPlay network with Mr Play, Prime Scratch Cards, Slots Cafe, Casino British, Quid Slots and Casino Kings, among many other skins on the same licence. Sunny Casino itself names Casino Kings as a sister.
Are Sunny Casino sister sites on GamStop?
Yes. Every UKGC-licensed ProgressPlay brand is covered by GamStop, so a self-exclusion applies across the network.
Is Casino Kings a Sunny Casino sister site?
Yes. Sunny Casino names Casino Kings in its own footer, and both are ProgressPlay brands on the same UKGC licence (39335), so it is a genuine, confirmed sister.
Is PlaySunny the same as Sunny Casino?
No. Despite the similar name, PlaySunny is run by a different operator (Dazzletag) and is not a ProgressPlay sister. Sunny Casino (sunnycasino.com) is the ProgressPlay brand covered here.
What is the best Sunny Casino sister site?
Mr Play for most players, a bigger, better-supported brand on the same platform. For instant wins, Prime Scratch Cards; for a fuller slot grid, Slots Cafe.
Is my money protected at Sunny Casino?
It is UKGC-licensed and GamStop-covered, but ProgressPlay holds player funds at the UKGC “Not protected” segregation level, so balances are not ring-fenced to the highest tier if the operator fails.
Our Verdict on Sunny Casino
Sunny Casino is a cheerful, perfectly usable ProgressPlay skin with a better-than-average instant-win corner, but the “Not protected” fund status, ProgressPlay’s regulatory history and the sheer sameness across the network hold it to a 5. Of the Sunny Casino sister sites, my pick is Mr Play: same platform and licence, but a bigger, better-supported brand with a stronger promo calendar. If scratchcards and instant wins are your reason for being here, Prime Scratch Cards is the more focused choice. Sunny suits casual players who like a bright lobby and a flutter on instant wins.
