Dukes Casino Sister Sites: The ProgressPlay Network Explained

Dukes Casino sister sites include Mr Vegas Casino, Monster Casino, Fruity King, Mr Slot, Spinzwin and Mako Casino, alongside dozens more white-label brands built on the same ProgressPlay platform. They share an operator (ProgressPlay Limited), a UK Gambling Commission licence and near-identical bonus rules, so the main thing that changes from one to the next is the theme, the welcome spins and the size of the slots lobby.

Dukes Casino Sister Sites in Full

A quick note on the term. Dukes itself does not publish a tidy “official sister sites” page. What people mean by the phrase is every other casino run on the same licence and platform. On this page that means the ProgressPlay network: brands owned and operated by ProgressPlay Limited under the same UK Gambling Commission licence, which is the common UK search meaning of a sister site.

Best Dukes Casino Sister Sites at a Glance

• Best overall: Mr Vegas Casino, the most polished and best known ProgressPlay brand.
• Best for promotions: Monster Casino, which leans on spins-led welcome offers.
• Best for mobile and pay by phone: Fruity King, built around quick mobile play.
• Best for slots: Mr Slot, a straight slots-first skin.
• Best for sports and casino together: Spinzwin, which pairs a sportsbook with the casino.
• Best plain alternative: Mako Casino, a no-frills version of the same platform.

Dukes Casino Sister Sites Compared

Offers move around and all now sit under the UK 10x wagering cap that came in on 19 January 2026, so treat the welcome column as a pointer and read the current terms on each site.

Mr Vegas Casino

Run by ProgressPlay on the same UKGC and Malta licences as Dukes, Mr Vegas is the network’s flagship. The lobby is the largest of the bunch, with slots from NetEnt, Pragmatic Play, Blueprint and Big Time Gaming plus a live casino. Payments cover debit cards, PayPal and the usual e-wallets, and support is 24/7 live chat. Versus Dukes: the same platform underneath, but a deeper game list and a more recognisable brand.

Monster Casino

Monster Casino is a spins-led skin on the ProgressPlay platform, pitched at players who chase regular promotions. Game range and providers are the network standard, and the bonus calendar is the draw. Versus Dukes: more promo-driven, the same licence and cashier behind it.

Fruity King

Fruity King grew out of the pay-by-mobile era and still feels built for phones first. Slots dominate, deposits by card and mobile-friendly methods are quick, and the design is light. Versus Dukes: a mobile-first take on the same games rather than a different casino.

Mr Slot

Mr Slot is exactly what it sounds like, a slots-first ProgressPlay brand with a smaller table-game and live section. Same providers, same UKGC cover, same withdrawal process. Versus Dukes: narrower by design if all you want is reels.

Spinzwin

Spinzwin pairs the ProgressPlay casino with a sportsbook, so it suits players who want a bet and a spin in one account. The casino half mirrors Dukes; the sports side is the extra. Versus Dukes: adds betting markets Dukes does not carry.

Mako Casino

Mako is one of the platform’s plainer skins, with a clean lobby of 250-plus slots from the usual providers and a modest welcome offer. Versus Dukes: a pared-back twin, useful if you want the same games without the marketing.

Sin Spins

Sin Spins is a newer ProgressPlay slots brand with a darker theme and the same back office as the rest. Versus Dukes: a fresher coat of paint on familiar machinery.

Dazzle Casino

Dazzle Casino is a long-running ProgressPlay skin with a bright design and a slots-led lobby. Versus Dukes: very similar in practice, down to the cashier and terms.

The Complete ProgressPlay Sister Sites List

ProgressPlay runs a large white-label network, so the family is far bigger than the brands reviewed above. The actual related sites split roughly into three groups.

• Casino skins: Mr Vegas Casino, Monster Casino, Fruity King, Mr Slot, Mako Casino, Sin Spins, Dazzle Casino, Royal House Casino, Top Slot Site, Yoko Casino and Lumo Slots.
• Sports and crossover brands: Spinzwin, Winston Bet, Gatobet and Bet Dukes.
• Bingo-led brands: Bubble Bingo and other small skins on the same licence.

ProgressPlay operates well over a hundred UK-facing sites, so any single list is a snapshot and older affiliate pages still name brands that have since closed. The reliable way to confirm a brand is a true sister is to read the operator name in its footer and terms, then look up ProgressPlay Limited, account number 39335, on the UK Gambling Commission register.

What Is the Same and What Is Different

Are These Official Dukes Casino Sister Sites?

It helps to separate three things people lump together. There is no official Dukes “brand family” of regional versions; it is a single white-label site. The same-operator network is what this page covers, the other ProgressPlay brands on licence 39335. And then there are unrelated casinos that simply look similar or appear in the same lists, which are not sisters at all. Older pages mixing in names like 888 Ladies, Casimba or Casino Heroes are wrong; those run on different operators and licences entirely.

Dukes Casino Review

Dukes Casino has been around since roughly 2012 and is one of more than a hundred UK-facing brands ProgressPlay runs on its white-label platform. That shapes the whole experience: the lobby, the cashier and the terms are shared with its sisters, so the review below applies, give or take a theme, to most of the network.

Operator details last reviewed: June 2026 (last updated 8 June 2026)

Updated June: corrected the operator and licence details, removed the stale dated sister lists, and added ProgressPlay’s August 2025 UKGC penalty.

Welcome offer and promotions

Dukes runs a match-plus-spins welcome offer. Since 19 January 2026 every UK bonus here sits under the 10x wagering cap, which is a real improvement on the old 35x and higher terms these brands used to carry. Watch the detail though: ProgressPlay caps the cash you can convert from a welcome bonus and limits how many of its brands you can take a new-player offer from, so read the live terms before depositing.

Games and providers

The library is the network pool: slots from NetEnt, Pragmatic Play, Blueprint and Big Time Gaming, a live-dealer section and the usual table games. It is a solid, familiar catalogue rather than a standout one, and it is close to identical across the sister sites.

Payments and withdrawals

Deposits and withdrawals run through debit cards, PayPal and common e-wallets in pounds. Cashouts usually land in one to three working days once identity checks clear. The recurring gripe in player reviews across ProgressPlay brands is slow withdrawals and document requests at the cashout stage, so verify your account early to avoid a hold-up.

Support and responsible gambling

Support is 24/7 live chat with email backup. As a UKGC brand, Dukes is covered by GamStop self-exclusion and offers deposit limits, time-outs and reality checks. If gambling stops being fun, GamCare and BeGambleAware can help, and GamStop lets you self-exclude across all UK-licensed sites at once.

Mobile

There is no separate app; Dukes runs in the mobile browser, and it is built to work on a phone. Sisters like Fruity King lean even harder into mobile-first play.

How it compares to its sister sites

Honestly, Dukes is a mid-table option in its own family. Mr Vegas has the bigger lobby and the stronger brand, Spinzwin adds sport, and the rest are close cousins. The bigger point sits above the individual brands: in August 2025 the UK Gambling Commission fined ProgressPlay one million pounds for anti-money-laundering and customer-interaction failings, its second enforcement action after a penalty of about 175,000 pounds in 2022. That belongs in any honest read of the whole network.

Pros and Cons

Pros

• Properly licensed for the UK by the Gambling Commission (and by Malta), so GamStop and IBAS cover apply.
• One familiar account style and cashier across the whole ProgressPlay network, easy to move between brands.
• A broad shared games pool from NetEnt, Pragmatic Play, Blueprint and Big Time Gaming.
• The 10x UK wagering cap now applies to its bonuses, far better than the old high-multiplier terms.

Cons

• ProgressPlay was fined one million pounds by the UKGC in August 2025 for AML and social-responsibility failings, its second such action.
• Player reviews regularly flag slow withdrawals and heavy document checks at cashout.
• Many sisters are near-identical skins, so the “choice” is often cosmetic.
• Welcome bonuses come with a low conversion cap and a limit on how many network brands you can claim from.

Our Verdict on Dukes Casino

Dukes Casino is a fair, average UKGC casino that mainly earns its place as a doorway into a very large network. If you want the best of the Dukes Casino sister sites, Mr Vegas Casino is the pick: same operator and licence, but a bigger lobby and a more established brand. Treat the network with open eyes, ProgressPlay’s one million pound 2025 fine and the steady withdrawal complaints are why this lands at a 5, not higher. It is fine for casual slots play; it is not the place for anyone who wants fast, no-fuss cashouts.
