Our original mFortune sister sites review was a couple of months ago, and a lot has changed since then within the walls of Skywind, owner of nearly a dozen gambling-related sites in the UK.

In the months following the Skywind buyout, the mass layoffs, and the general decline in customer support, the Bonus Boss Sister sites have been active. Some startling transformations have taken place on each site and within the Skywind stable as a whole.

Reviews of Bonus Boss Sister Sites

Many of these sites share the same pool of slots and casino games, the main difference will be additional features and exclusive content. Of course, the oldest of these sites will have more of a history to examine, so we might be able to find the root cause of the issues we covered in our honest Bonus Boss review.

Let’s look at the Bonus Boss sister sites in more detail.

Mr. Spin – Bonus Boss Sister Sites

Mr Spin - Dr Slot Sister Sites
Mr Spin Homepage

Mr. Spin is a site that focuses mainly on slots, bingo, and roulette. Bonus Boss with bingo options and a few of the older InTouch games were added since it was opened in 2016. But it also needs to be more feature-rich.

For example, while there’s a search icon available at Bonus Boss, even if you aren’t logged in, you can’t search the available slot machines at Mr. Spin from the default home page or slots page.

There are games available on Mr. Spin that need to be added to Bonus Boss: terrific TudorsRed Hot Prizes, and more. As of early August 2023, Mr. Spin has around twice as many slot titles as Bonus Boss.

This includes absolute trash, like Dog Detectives and its pitiful 90.11% RTP. And, of course, Red Devil Reel, a legendarily wrong InTouch title with a listed RTP of 89.99%. Real money slot games like that should be illegal, but as mentioned, the UK has no minimum RTP standards. Just avoid them at all costs.


As far as bonus offers, expect the usual 40x rollover. Given that the average slot on the site has around a 94% RTP, good luck clearing any of the bonuses they offer.

The No Deposit Bonus is 50 Free Spins, with a 40x rollover on any winnings. The average First Deposit Bonus is 100% Matching Up To £100. But the average player will never clear any of that, as mentioned above.

Mr. Spin has a minor focus on bingo, providing only three or four bingo rooms at any time. Their Bingo Mega Jackpot starts at £10,000 and ranges up, currently at £29,000 (in early August 2023). You need a Full House in 31 calls or less to claim it. Playing earns you points towards a Loyalty Shop that includes online vouchers and bonus credits at the higher end.

Mr. Spin used to have the worst TrustPilot rating of all the Bonus Boss sister sites but has crept up a tenth of a point while Casino 2020 has fallen to the lowest spot.

Still, Mr. Spin is pretty awful. Try it if you agree with the lackluster support, terrible RTP, uninteresting bonus structure, and lack of public trust. We wouldn’t.

Casino 2020 – Bonus Boss Sister Sites

Casino 2020 Homepage
Casino 2020 Homepage

Casino 2020 is a high variance-focused site, at least in name and advertising.

In reality, they use mostly the same game suite as Bonus Boss, swapping some titles in and out but maintaining around 60 total slots at any given time – no bingo on this one.

The old ‘UP TO’ clause on your bonuses is part of the site’s random element. For example, the no-deposit bonus is UP TO £20 and 20 Free Spins. The first deposit bonus is UP TO £300 and UP TO 400 Free Spins. Of course, it’s a 40x rollover on some crappy RTP slots, so good luck.

You may have heard about RTP tanking on other sites. It’s also apparently present on the older Bonus Boss sister sites, such as Casino 2020.

Spin A Clue offered a 94.51% RTP back in 2022. Now it’s just 94.13%, which is 0.39% lower than it used to be.

Operation Wilds used to offer a 94.62% RTP, 0.52% higher than the 94.1% RTP on offer now. 

These little percentage changes represent hundreds of thousands of extra quid taken from players’ pockets and deposited into the casino’s bank account, given how terrible some of their other slots are, like Empire’s Treasure with an underwhelming 91.99% RTP or Amityville with a horrible 90.04% RTP… why would a company get so greedy as to nerf slots that are barely above 94.5% RTP?

Of all the Bonus Boss sister sites, Casino 2020 is the worst. And that’s not just our opinion; they’re also the lowest-rated of these sites on Trustpilot. But we can see why: Unimpressive game selection, terrible RTP, odds tanking, and questionable support all contribute to this fading and tattered mural. Avoid them if you can.

Cashmo – Bonus Boss Sister Sites

Cashmo Casino Homepage

Cashmo is another pure slot site, added to the Bonus Boss sister site list since they share a license with the other InTouch-managed sites. They’re a slots-only site focused on mobile play; they still function in a traditional desktop browser just fine.

First impressions are essential, as this is our first review of this site. But Cashmo’s four new featured slots are around 92% RTPHowl At The MoonMega Mr. MonsterTomorrow’s Fortune, and Golden Road. Another page also pushes Win Mixer with an RTP right around 92%. Talk about a terrible introduction to the site.

But as it turns out, it doesn’t matter. Because if you try to read about their bonuses, you’ll see that they’re closing their doors and opening up a brand new casino instead. But the casino they’re pushing is under a completely different license and potentially other ownership!

This makes no sense, particularly when they’re also shilling the other Bonus Boss sister sites. Given that they’re a short-term presence, we do not suggest opening an account at Cashmo now. Sometimes it’s a nightmare to reclaim your funds when a casino closes its doors. Don’t opt into that pain.

PocketWin – Bonus Boss Sister Sites

Pocketwin - Dr Slot Sister Sites
Pocketwin Casino Homepage

PocketWin Casino is a mobile-optimized Bonus Boss sister site that features real money online bingo, casino, and slot games.

Most of their featured slots are around 94% RTP, which is better than most other sites we’ve gone through. Cheese Chase is a disappointing 92.66% RTP, but most other home page slots are typical, bland InTouch offerings.

PocketWin’s casino offerings include Roulette and Blackjack, each offering an RTP of over 97% with optimal play. But they only count for 10% of your bonus rollover.

Not that it matters because it’s the same awful 40x rollover offer as the rest of the Bonus Boss sites. The No-Deposit Bonus is £10, and the first deposit bonus is a 200% Deposit Match Up to £100. Good luck clearing them, however.

The five bingo rooms each have their progressive jackpot. Progressives are claimed when you hit a whole house before the 35th call. A bingo loyalty points program can earn free tickets in their PocketWin Bingo Reward Store.

But PocketWin’s support is similar to the average Bonus Boss sister site, and their average RTP is low. If you play here, try to have fun because you’re unlikely to make any money.

Dr. Slot – Bonus Boss Sister Sites

Dr Slot Homepage
Dr Slot Homepage

Dr. Slot is precisely what it says on the tin: A slots-only Bonus Boss sister site.

The casino has a friendly GUI, possibly the most pleasant of all the sites we’ve reviewed in this article. But it’s still feature-poor, lacking filters or a search mechanism for the slots from the default homepage. Looks aren’t everything. 

It suffers the same drop in RTP that many of the other Bonus Boss sister sites have. 

For example, their game of the month for August 2023 is Doom Lord. Like other featured machines on the site, it sits at a terrible 92% RTP. The same goes for their other featured new slots, Secret StarsJuiced Fruits, and Wild Volcano, all within 0.05% of that low 92% RTP mark.

Their first deposit bonus is strange since it caps at £50 for the First Deposit 300% Matching offer. Why so low? Who knows. The 40x rollover requirement on such awful RTP machines makes it a moot point.

Like all Bonus Boss sister sites, Dr. Slot needs better support, needs a better average RTP, and will likely waste your time. Pass on this one.

Jammy Monkey – Bonus Boss Sister Sites

Jammy Monkey - Dr Slot Sister sites

Imagine a version of Bonus Boss with some interesting bells and whistles but still offering 92% and 94% RTP slots, and you have a good idea of what Jammey Monkey has to offer.

Jammy Monkey have a ton of Slot Factory machines and Skywind-owned devices. They even have a short-term RTP report that shows hot and cold streaks. Of course, RTP reports over the short term (a day or a week) are meaningless fun. But at least it’s fun.

Problem: Jammy Monkey’s bonus structure is identical to other Bonus Boss sister sites. It’s typically a high variance, 40x wagering requirement clown fiesta. But at the time of reporting, their bonuses showed a July special, even though it had already expired, as we ticked over to August.

Jammy Monkey might differ from many other Bonus Boss sister sites, but it shares some essential aspects: Bad Trustpilot ratings, low RTPs, and questionable support. No need to give this one a second glance.

mFortune – Bonus Boss Sister Sites

MFortune Casino Homepage
MFortune Casino Homepage

mFortune offers slots, bingo, and casino games, making it a more flexible Bonus Boss sister site.

Typical of what we’ve seen at other Skywind sites, the four new ‘feature’ slots are around 92% RTP: Slot FactoryOne Step BeyondChicago Boss, and Queen of the East. They never miss an opportunity to push low-value crap at their users.

mFortune’s casino games are mostly roulette and blackjack variants. The proper variants are, with perfect play, over 97% RTP. Check the RTP of the variant you want to play and avoid side bets, as they tend to have awful returns. And as you might notice from earlier reviews, remember that blackjack and roulette only count 10% towards bonus clearance.

The bingo room allows you to play slot machines during a 90-ball match. It’s usually an eleven-room setup, the most bingo selection of any Bonus Boss sister sites. Each of them has their jackpot to aim for, with the progressives triggering when all 15 numbers are called on a single ticket, in 35 numbers or less.

There’s also a Bingo-oriented bonus: Deposit £10, Get Up to £20 in bonus money. The 40x rollover requirement means a slow, painful clearance process. Other options are a £10 No Deposit bonus and a 100 Free Spins casino welcome bonus. Both of these are subject to the exact 40x wagering requirement.

mFortune has been around for over 15 years, but its years under Skywind’s thumb have weighed heavily on the poor old gal. Reviews are terrible, RTP is worse, and the rollover requirements are sad. Steer clear unless you have a specific reason to play here.

An Honest Bonus Boss Casino Review

Bonus Boss is one of InTouch’s newest casinos, launched in 2023. This site is offering a great variety of online slots and casino games. We can find no bingo rooms or slingo games after poking around (indeed, no separate category). They have no live casino offerings or sportsbooks either.

That means we must focus on Bonus Boss’ real money slot machines. You won’t find any of the popular third-party brands here since every slot on the site was developed in-house by InTouch games. Is that a good sign or a bad sign? Let’s have a look.


At the beginning of August 2023, we can find the following slots being advertised on their homepage:

  • Masks of Medusa with an RTP (Return to Player) of 92.04%
  • Steps to Heaven with an RTP of 92.03%
  • Aztec Flame with an RTP of 92.01%
  • Animal Kingdom with an RTP of 92.04%

These are some terrible slots to be advertising. The industry average RTP in the UK is generally 95%, a touch lower. Each is 2% to 3% lower than we’re used to seeing.

But instead of harping on this, let’s look at the new slots page to see if any of the additional machines being featured have a better return rate:

  • Bronco Buck$ with an RTP of 91.90%
  • The Gambler’s Arms with an RTP of 92.01%

Remember that Masks of Medusa is also their Game of the Month. That means free spins on their monthly promotion are at 92.04% RTP. Yikes!


These RTPs have to be considered quite greedy regarding real money online casinos. However, it is entirely legal. UK regulators do not impose minimum RTP standards for online slots and other RNG-based games.

And you might find complaints about this scattered among their 1-star reviews on Trustpilot. Still, the vast majority of negative reviews are about slow or no payouts (reviews quoted with exact spelling and grammar):

Deposited £200, won £400, asked for id, sent the required verification forms, five weeks later no money, they won’t answer the phone.’

I won £70 on Friday, and my money still hasn’t arrived. I’ve sent in all my documents emailed around seven times when just getting the same email to send in all my details which I have done around three times. I keep going on live chat, and no agent is coming through.’

Like everyone else, I am having trouble getting the money back that I deposited into the account, and they are now ignoring my messages on live chat and text messages.

This is a prevalent theme. A frighteningly large percentage of the negative reviews are about withdrawal attempts being canceled or never being started in the first place after an in-depth ID process.

That makes their promotional section a joke because who cares what they’re offering if they refuse to pay out? But for completeness’ sake, let’s have a look.

Bonus Boss Bonuses

There are various Bonus Boss bonuses available. The first is a 200% Match on a New Deposit – Max £100. So if you deposit at least £50, you’ll get £100 to clear. Of course, even if you find a 95% RTP machine, the 40x wagering requirement shuts down all but the luckiest players. The average player will lose 5% of every rollover, a total loss of 200% of the bonus amount. Lovely.

The same applies to the Up to 100 Free Spins – No Deposit bonus. Any winnings must be cleared via a 40x rollover; we already know the maths. The reload bonus is also a 40x rollover. Without 97% and 98% RTP machines to clear it on, it’s a reasonably hopeless venture for 90% of people. But you can try.

Note that some of the bonuses say ‘up to.’ That’s because the exact premium is determined by random chance via a ‘lobby game.’ It’s possible to get fewer free spins or a lower percentage bonus. This includes the Refer A Friend Bonus, giving you UP TO £10 when they register, plus UP TO 50% of their first deposit. Ridiculous, predictably, in light of the complaints from those who succeed, that making a withdrawal is like pulling teeth.

Payment Options

Deposit methods at Bonus Boss include debit, PaySafeCard, PayPal, and debit from your phone bill. Withdrawal methods include Bank Transfers, Debit Cards, and PayPal.

To summarize, Bonus Boss has a limited selection of games developed in-house, a lower-than-average RTP, slow customer service, random bonuses that are difficult to roll over, and a bad public reputation. Not exactly inspiring.

Let’s look at the Bonus Boss sister sites to see if they can do better.

Who Owns the Bonus Boss Sister Sites?

Technically, the owner of the record is InTouch Games Limited. They were based in Halesowen, England, at the time of initial site registration with the UK Gambling Commission. They currently hold license number 2091.

This ownership structure was changed in 2022 when Skywind acquired InTouch. They, too, are registered with the UK Gambling Commission, though they have not chosen to move the Bonus Boss sister sites onto their license, which is #52261.

Is Bonus Boss Safe and Legit?

The Bonus Boss sister sites are ‘legit’ regarding having a valid UK license.

However, they have been sanctioned twice in two years for anti-money laundering and social responsibility breaches. And while this isn’t the most serious of infractions that the Commission can levy, to have a repeat fine 22 months later is ridiculously careless.

This questions the ‘safe’ aspects of the Bonus Boss sister sites. If you consider a multi-sanctioned, RTP-dropping, support staff firing company to be safe, you already have your mind made up.

But if you still need to figure it out, read on. This story gets even juicier as we move into early August of 2023! 

How Did Skywind’s Acquisition Impact the Bonus Boss Sister Sites?

We all know that Skywind fired their Halesowen support staff and moved to Birmingham, and then their public reviews started to take a nosedive. The Halesowen News tore them a new one, but things have calmed down.

We’ve recently added Cashmo to the Bonus Boss sister site pool, but weirdly they last had a single Trustpilot review in February 2023 when sorting by ‘most recent.’ Whether this is an issue with the system or has yet to add a single review in the past six months is still being determined.

As for the rest, Mr. Spin saw a gain, while four out of the eight sites in question saw a loss. It’s easier to drop even lower than they already had if you get virtually all 1-star reviews during those two months, precisely what happened.

The longer-term impact of Skywind’s acquisition of InTrust Games has been disastrous, at least as far as public opinion goes.

Let’s find specific reasons for this in our honest Bonus Boss review. Then we’ll do the same for the Bonus Boss sister sites.

Bonus Boss Similar Sites

If you want to experience a good mix of bingo, slots, and casino action but want a decent RTP and a fair support staff, try the Heart Bingo sister sites.

These Bonus Boss similar sites are precisely the opposite scenario that we demonstrated with the InTouch casinos: A mix of good bonuses and high RTP machine availability.

Of these four sites, we’ve narrowed the selection down to two: talkSport BET and Heart Bingo.

These are two very different sites. It’s the combination that will give you the best of both worlds that you’re entitled to.

Heart Bingo

Heart Bingo has some of the best bonus offers in the business. They specialize in bingo and slingo.

The best news is that certain bonus offers on Heart Bingo don’t have any rollover requirements! If you deposit and gamble that value just once (to avoid money laundering issues), you’ll automatically get the free stuff they advertised. Paypal deposits don’t qualify, only debit cards.

For example, if you opt-in and wager £10 within your first week on the site, you can get up to £30 on Bingo + 100 Spins on Make Me a Millionaire. In this case, the ‘up to’ has nothing to do with an RNG… you need to make sure you’re playing in the 10p rooms and not the 1p rooms, that’s all! The tickets can be used for 1p play, but why would you?

talkSport BET

This is the best for non-bingo play with great miscellaneous bonus offers.

They have a sportsbook, which is better than any Bonus Boss sister site. But even if you have no interest in that, their general bonuses are much easier to clear. For example, the £35 in Bonuses and 50 Free Spins deal only requires a £25 deposit to be wagered on selected events. Then you receive seven days of small bets, plus 50 free spins on Big Bass Bonanza. The rollover requirement is only 20x the bonus amount. The max wins on the bonuses are £250 on the casino side and £25,000 on the sportsbook side, but you’ll have decent chances to clear them with higher RTP machines and reasonable odds on the sportsbook side.

The combination of better bonus offers at the Heart Bingo sister sites and a far wider variety of games is more than enough to recommend them over Bonus Boss. But they also have far superior customer service. Their Trustpilot reviews reflect that and their rock-steady commitment to fair play. Remember to avoid Paypal deposits if you want to partake in the bonus offers and read the terms and conditions of each offer you opt into.


You should opt into the Heart Bingo sister sites rather than go through the painful experience that the Bonus Boss sister sites bring.

The Bonus Boss sister sites have had plenty of time to make better decisions. The Skywind takeover has negatively impacted public perception of these sites and their operation.

Pushing these 92% RTP slots on the front page is cringeworthy… but even having sub-91% RTP slot machines on your site says something. It’s plain greedy and shows an utter lack of respect for your customers.

This, in addition to the terrible Trustpilot reviews and some of the most heartless corporate actions we’ve seen taken by a UK casino, means we wouldn’t recommend the Bonus Boss sister sites if you have other options available.

The team here at Sister Casinos will continue to monitor these sites for improvement. Maybe the closure of Cashmo suggests that a big move is about to take place. We’ll start to research this new license to see if they’re a shell company or a subsidiary that will do the same thing as the Bonus Boss sister sites. Until then, be careful out there!
