Short version: yes, QuidSlots has sisters, and there are a lot of them. The site runs on ProgressPlay Limited's platform, and ProgressPlay holds one UK Gambling Commission licence (account 39335) that also covers well over a hundred other casino, bingo and betting brands. So this is a UK-licensed white-label site sitting inside a very large network. It is not a lone offshore casino operating outside the UK system.
If you landed here believing QuidSlots was an offshore, non-UK operation, that is worth clearing up straight away, because it changes what protection you actually have. The mix-up is easy to make. ProgressPlay is run out of Limassol in Cyprus and also licensed in Malta, so the company itself genuinely sits abroad. The UK-facing site you would play on, though, operates under the British licence, and quidslots.com is listed among ProgressPlay's licensed domains on the regulator's own register.
The operator is ProgressPlay Limited, a white-label platform business. White-label means ProgressPlay builds and runs the casino engine, holds the licences, processes the money and handles support, while each individual brand on top is mostly a skin: a name, a colour scheme, a welcome offer. QuidSlots is one of those skins.
The UK Gambling Commission's public register entry for ProgressPlay gives a head office at Kolonakiou 26, Limassol, Cyprus, with the remote casino permission active since 1 November 2014, general betting since December 2018 and bingo added in August 2024. All three permissions show as active. That entry is the primary source that matters, and it is the one to trust over any affiliate summary.
What this means for you as a customer is simple enough. When you deposit at QuidSlots, upload your ID or chase a withdrawal, you are dealing with ProgressPlay's systems and staff, not a separate company called QuidSlots. It also means the experience will feel almost identical at its sister brands, because underneath they are the same machine.
The verifiable part is solid. QuidSlots operates under ProgressPlay's UK Gambling Commission licence, account 39335, which is marked active for casino, betting and bingo. That comes straight from the regulator, and it is what governs your UK protections.
ProgressPlay also states that it holds a Malta Gaming Authority licence, which is what powers several of its .com brands in non-UK markets. We could not independently confirm the exact MGA licence number on the MGA's own register while writing this, so we are not going to print one. If that number matters to you, take it from ProgressPlay's own terms and check it against the regulator's site rather than trusting a figure copied from one affiliate page to the next. The same caution applies to anyone quoting a precise payout percentage or an exact bonus wagering multiple for QuidSlots. Network terms shift, and stale numbers get repeated for years. Read the offer that is actually in front of you when you sign up.
Every brand in the table below shares the same operator and the same UK licence as QuidSlots. The rows are drawn directly from the domains registered to ProgressPlay (account 39335) on the Commission's register, so the shared-operator link is confirmed rather than inferred from a "similar casinos" widget.
| Brand | Operator | Note |
|---|---|---|
| Glimmer Casino | ProgressPlay Limited | Same UK licence (39335); listed as an active ProgressPlay domain |
| Quartz Casino | ProgressPlay Limited | Same UK licence; UK-facing .co.uk brand on the register |
| Yako Casino | ProgressPlay Limited | Same UK licence; long-running ProgressPlay skin |
| Sunny Casino | ProgressPlay Limited | Same UK licence; active ProgressPlay domain |
| Lucky Pro Casino | ProgressPlay Limited | Same UK licence; active ProgressPlay domain |
| UK Slots | ProgressPlay Limited | Same UK licence; active ProgressPlay domain |
| Mobile Slots | ProgressPlay Limited | Same UK licence; active ProgressPlay domain |
| Casinomite | ProgressPlay Limited | Same UK licence; active ProgressPlay domain |
That is a small slice. ProgressPlay's estate runs to well over a hundred live and retired domains, so a "QuidSlots sister sites" list is really one cross-section of a single enormous network. The practical takeaway is dull but useful: opening accounts at three or four of these means signing up with the same company three or four times over, with the same wallet checks, the same support desk and the same terms behind them.
Because QuidSlots is UK-licensed, you do get the standard British protections, including a route to the operator's complaints process and then to an approved alternative dispute resolution service if you cannot settle a dispute. That is a real advantage over a genuinely offshore casino. It does not make the brand a soft option, though, and there are specific things to weigh.
The operator's recent regulatory record. This is the most important single fact about ProgressPlay, and it applies to QuidSlots along with every sister. On 9 May 2025 the Gambling Commission imposed a £1,000,000 penalty on ProgressPlay, alongside a warning and an ordered third-party audit, for anti-money-laundering failings and for breaching the social-responsibility rules on how it interacts with customers who may be at risk. A fine of that size is not a formality. It tells you the operator's player-protection and money-laundering controls were found wanting recently, so keep your own records and expect thorough identity and source-of-funds checks.
How the network handles limits and exclusion. Registering with the national online self-exclusion scheme blocks QuidSlots and every other ProgressPlay brand, along with all other UK-licensed operators, because taking part in that scheme is a condition of the UK licence. A deposit limit is different: it applies to the single account you set it on, so a limit you set at QuidSlots does not follow you to a sister brand, and you would need to set one again there. A network-wide welcome bonus also generally counts once across the estate rather than fresh at each brand, so chasing the "new player" offer round the sister sites is not the free run it looks like.
Bonus terms and reputation. Independent reviewers give QuidSlots a low overall safety rating and have logged player complaints about slow or stalled withdrawals during verification. Treat headline offers with care, read the wagering requirement and the maximum bonus-withdrawal cap before you deposit, and do your identity checks early so a payout is not held up later.
QuidSlots is a legitimate, UK-licensed place to play, and it is straightforwardly part of the ProgressPlay family rather than an offshore outlier. But it is a thin brand on a big shared platform whose operator was fined a million pounds in 2025 for anti-money-laundering and player-protection failings, and independent ratings for the brand itself are weak. If your real question is whether to trust QuidSlots or one of its sisters, the honest framing is that you are choosing whether to deal with ProgressPlay, because that is who you are dealing with either way. A UK-licensed operator with a cleaner enforcement record is the safer choice, and there are plenty of them. If you do play here, set your deposit limit yourself, keep evidence of every transaction, and read the current bonus terms rather than any figure quoted second-hand.
