Dukes Casino sister sites 2025

Sin Spins

Some people believe that gamblers are sinners. Sin Spins is a casino site that supposes that if you’re being accused of sinning, you might as well go with the flow. There can’t be many iGaming sites out there literally themed after the idea of being in Hell, but we can all think of a few that make us feel like we’re there! Needless to say, Sin Spins is the only one of the Dukes Casino sister sites that uses this theme. It’s topped with an attractive model dressed in a Halloween-perfect naughty devil outfit on the homepage – an image that some players might think is both dated and sexist. We’re not here to pass judgement on that. We can judge Sin Spins on its content, though, and perhaps its biggest weakness is that it doesn’t have anything that you haven’t already seen at Dukes Casino. It uses the same template-based design, too – but that’s true of a lot of the Dukes Casino sister sites.

Vegas Mobile Casino

How long have you been playing at online casinos? If your answer to that question was, “More than five years,” you’ll probably remember a time when online casinos came in two different formats. There were casinos designed to be loaded on desktop or laptop computers, and there were casinos designed to be loaded on mobile phones or tablets. These days, the same casino sites load just as easily on any form of media. That means that the time for sites like Vegas Mobile Casino has been and gone. There’s no longer a need for mobile-focused casino sites, but you’ll find a couple of them among the Dukes Casino sister sites anyway. There’s nothing empirically wrong with Vegas Mobile Casino – it has access to the same selection of games as Dukes Casino itself – it’s just not a very exciting website to look at. Still, if bandwidth matters to you, or you have an older phone that struggles to cope with modern casino sites and all their flashy graphics, Vegas Mobile Casino might work as a convenient solution.

Monster Casino

Monster Casino is the benchmark when it comes to Dukes Casino sister sites. It’s the unofficial flagship of the ProgressPlay Limited casino network and the measuring stick against which all the other iGaming sites on the platform are judged. With very few exceptions – perhaps only one or two – they all come up short. We’d be surprised if you haven’t seen the Monster Casino brand advertised somewhere if you’re an experienced online casino player. It’s the most heavily promoted of all the Dukes Casino sister sites, and its logo is familiar to thousands of players. Fittingly for a casino of such status and repute, the welcome promotion at Monster Casino is potentially worth an enormous one thousand pounds. May close attention to the terms and conditions of that seemingly-generous offer, though; you may find that the bonus is too sticky to justify the large spend that’s required to take full advantage of it. From slots to sports betting, Monster Casino offers everything you could conceivably want to bet on except for bingo.

Winston Bet

For the main part, you can divide the Dukes Casino sister sites into two camps. There are sites that specialise in sports betting, and there are sites that specialise in regular casino games. Winston Bet belongs to camp one and is one of the newer additions to the ever-expanding roster of ProgressPlay Limited white-label iGaming sites. It couldn’t have picked a worse year to go live in. 2020 was a year of death for sports betting sites on account of professional sports grinding to a halt all over the world, and it was also the year that Winston Bet made its debut. It can’t possibly have made more than half the money it expected to make during its debut year, but it found a way to survive and is now looking to expand. We’ve noticed a lot of promotional activity around Winston Bet in the past twelve months, so whichever white-label partner ProgressPlay Limited works with on the site is clearly prepared to put time and money into making a success out of it.

RH Casino

RH Casino uses the same template as both Winston Bet and Sin Spins. We wouldn’t normally have an issue with that – as we’ve said before, you’ll find the same template providing the foundations of a lot of the Dukes Casino sister sites – but we have an issue with it in relation to RH Casino. The site’s full name is Royal House Casino, and it’s clear from both the casino’s logo and the choice of images on its homepage that it thinks of itself as a first-class casino. It wants to emulate the style of the kind of real-world casino that expects you to dress up in your finery, or you’ll be turned away at the door. The ProgressPlay Limited template looks fine, but it isn’t well-suited to that kind of market. As a result, RH Casino looks like a member of the Dukes Casino sister sites family which has developed delusions of grandeur. If it wants to chase the VIP market, it needs a bespoke look and a better welcome promotion.

Mako Casino

If you’re looking for evidence that the ProgressPlay Limited basic design template is overused, here it is; we picked the Dukes Casino sister sites for this section of our review page at random (you’ll find a full list of all of them at the bottom of the page), and yet Mako Casino makes it three sites in a row that use the same template. Of the three, Mako Casino is the closest to Winston Bet in form and function. Winston Bet comes across as a sports betting site that also offers casino games, though. Mako Casino comes across as a casino site that also offers sports betting. Emphasis aside, you’ll find the same games and betting opportunities available at both sites. You may even find that they’re listed in the same order. The network of Dukes Casino sister sites has strength in numbers, but there isn’t a whole lot of variety between them. If you like one of them, there’s a high chance that you’re going to like them all.

Dukes Casino Review 2025

Dukes Casino Sister Sites Welcome Bonuses

You don’t have to look very hard to find the welcome promotion at Dukes Casino – it’s positioned right in the middle of the casino’s homepage. New players can avail themselves of a 100% matched deposit with a maximum value of £100 and pair it with twenty bonus spins on Rich Wilde and the Book of Dead by Play’n Go. The same snags that apply to promotions at all the Dukes Casino sister sites also apply here – the bonus plus any free spins winnings are hindered by an x50 wagering requirement, and bonus conversion is limited to x3.

Other Promotions

Dukes Casino operates a “Rewards Programme,” which includes access to a Dukes Casino Rewards Store. To buy things from the store, you need rewards points. They can be obtained by completing the regular missions that the casino sets for its players, but further points can be accrued from other promotions and tournaments at the casino, plus making deposits and placing wagers. Points lead to promotion through the various Dukes Casino loyalty rankings, but they can also be exchanged for items in the store. Those items include standard casino perks like free spins, plus matched deposits of various values and allocations of bonus cash.

Top Games at Dukes Casino

We have to name Book of Dead as Dukes Casino’s top slots game, as it wouldn’t be attached to the casino’s welcome promotion if it wasn’t. It’s the greatest Egyptian-themed slots game of all time in the eyes of many players, and it comes from Play’n Go. The biggest graphic on the Dukes Casino homepage, though, features Gonzo from NetEnt’s equally classic Gonzo’s Quest slot. The well-animated adventure-themed slot is a firm favourite of thousands of players. Unsurprisingly, Barcrest’s genre-defining Irish-themed Rainbow Riches slot is listed first among the player favourites at Dukes Casino. Rainbow Riches is now a long-running franchise with over a dozen entries, but the original slots game with its “road to riches” bonus remains the favourite among players.

Customer Support and Licensing

The “support” button on the Dukes Casino homepage takes you to the ProgressPlay Limited customer service portal, which is shared by all the Dukes Casino sister sites. You can browse through the (extensive) FAQ for answers, start a chat with a customer service agent, or email customersupport@instantgamesupport.com and wait for an answer. The casino claims that support is available 24/7. Dukes Casino operates in accordance with the terms and conditions specified by ProgressPlay Limited’s UK Gambling Commission licence (no. 39335), but ProgressPlay Limited was deemed guilty of breaking some of those licence conditions – specifically those related to keeping customers safe and preventing money laundering – in May 2022. The operator settled the matter for £175,178 instead of facing a formal sanction.

Withdrawal Speed and Support

Alarmingly, some of the links at the bottom of the Dukes Casino website don’t work. That includes the casino’s “about us” page and the information page that covers withdrawals. We assume that withdrawals work the same way here as they do at most of the Dukes Casino sister sites, though. That means a 1% fee (up to £3) for all transactions, a one-day wait for all requests to be processed by the casino, and then a follow-on wait for funds to be transferred. Debit card customers face quite a long wait – it could take up to seven business days and will take at least three. PayPal customers fare no better, even though they ought to from a technical point of view. You can get a four-day withdrawal through ecoPayz, or a two-day withdrawal through Neteller.

Final Thoughts on Dukes Casino

Our review of Dukes Casino was going relatively well until we noticed that the important links in the footer of the site don’t work. That’s a basic maintenance issue and ought to have been checked and fixed immediately. We have to mark Dukes Casino down for that, which means you’re better off playing at one of the better-known Dukes Casino sister sites like Monster Casino. You’ll still face the same unreasonable wagering requirements and lengthy waits for withdrawals, though.
