The best way for me to explain why is, I think, to hit you with some figures. So, here’s a couple of tables comparing the average cash out times and top RTP games offered by today’s top three best payout online casinos. I’ll start with the withdrawal stats…

Next, let’s look at what each brand has to offer, RTP wise.

Best payout online casinos in the UK for RTP

Perhaps you came here looking for the best payout real money online casinos in terms of potential Return to Player or “RTP”, instead, eh?

If so, here’s what you need to know about BetMGM UK, Bwin and Matchbook’s highest RTP slot games – as well as what kinds of jackpots you can expect to have a shot at winning by way of each brand’s latest and greatest tournaments and events:

Best online casino payouts in the UK in terms of actual prizes won by players

Next up, here’s what I can tell you about recent, record breaking wins that past players have managed to land at some of these sites.

Now, the info I have is a bit limited here, because some winners like to keep these kinda details under wraps rather than shouting about it to the press, for obvious reasons. What’s more, it’s worth remembering that there’s never any guarantee of winning anything whenever you play at an online casino site. Nevertheless, here’s what I know:

  • BetMGM UK – not too long back, one Brit reportedly won £650,000 after betting just £1 on the Playtech slot game, Age of the Gods. Which, as we’ve seen, has a very competitive RTP of 96.14%.
  • Bwin – there isn’t much info out there right now regarding big Bwin winners of recent years, but I saw exciting prize pools of up to six figures advertised on games like Gold Strike whilst penning today’s guide.
  • Matchbook – likewise, past major Matchbook wins are a bit of a mystery, but get this: the site was running jackpots with £2,000,000 plus prize pools on their flagship 9 Masks of Fire: King Millions game at the time of writing. And I can confirm this particular game is epic fun to play.

Today’s best payout online casinos in the UK – a closer look at my three fave brands

Right, now I’ve covered all that, allow me to shed a bit more light on what BetMGM UK, Bwin and Matchbook each have to offer to gamers just like you and me, more generally speaking.

You see, if you’re serious about signing up with a market leading UK casino on mobile or web, it ain’t all about lightning fast withdrawals, RTP or even huge jackpots and prize pools.

IMO, bonuses, game selections, software and other features warrant careful examination, too. So, here’s what to expect on these - and other - fronts from my three favorite casino brands:

BetMGM UK – offering the best selection of high RTP games

If you’re trying to hunt down the best payout online casinos in the UK, BetMGM should definitely be on your radar.

The brand offers a dizzying selection of more than 1,800 different games, the bulk of which are great from a software standpoint, with many Pragmatic Play and MicroGaming-powered slots qualifying for frequent jackpot style promotions.

Whenever you fire up an eligible game, you’ll be able to chase three different tiers of exciting prize pools. Which, at the time of writing, were worth:

  • £25,615,374 for “Mega” jackpots
  • £28,470 for “Major” jackpots
  • £2,050 for “Minor” jackpots

What’s more, most slots here are serious about RTP, too, with the vast majority of the brand’s games offering at least 95% RTP or more to players.

On sign up, all Brits can qualify for a 100 bonus spins bonus that can be enjoyed on the classic slot, Big Bass Splash. Thereafter, you’ll be able to unlock all kinds of exciting casino promotions and tap into superfast withdrawals of just 1 to 30 minutes when cashing out via PayPal, Apple Pay or Google Pay. Not bad at all in my book.

Bwin – offering the fastest cash out times around

When it comes to narrowing down the best payout online casinos in the UK, one of the main criteria to consider is, of course, cash out times – which are pretty much unrivalled over on Bwin.

As we’ve seen, right here is a brand that’ll let you cash out instantly if you pick bank transfer as a payment option when requesting a withdrawal.

Their other cash out options are a little slower, but Bwin is certainly no slouch when it comes to unveiling and rotating regular jackpot style promotions, which routinely feature prize pools of six and seven figures, or potentially even more.

Better yet, I got a 100 bonus spins sign up bonus playable on the 96.09% RTP slot game Starburst when I registered here recently.

Later down the line, I enjoyed spinning my way through thousands of other eye popping slot games that were all offering RTP of 97% or more, including:

  • Blood Suckers (powered by NetEnt)
  • Starmania (powered by NextGen)
  • 1429 Uncharted Seas (powered by ThunderKick)

The software and graphics were top of the range across the board, and I was impressed to see that several table games and live casino experiences were up for grabs on the site also.

Matchbook – best for frequent prize pools and jackpots

So, if BetMGM UK excels on the RTP front and Bwin is fantastic for speedy cash outs, where does that leave Matchbook?

Well, oftentimes the best payouts at online casinos in the UK are secured by players who manage to hit it big on progressive jackpot games – of which, of course there is no guarantee. Nevertheless, Matchbook delivers hundreds of these kinds of games, and is always a pleasure to play at.

As pointed out in my RTP table earlier, staggering prize pools of up to £2,824,914 were advertised on medium RTP slots like 9 Masks of Fire: King Millions at the time of writing. Meanwhile, other exciting games, like Mega Fortune for example, were offering a chunk of £142,908 to leaderboard toppers.

But that’s not all. I found that new players registering with the brand from the UK would get 200 bonus spins playable on 9 Masks of Fire from the get go, while jackpot promos of the kind described above were being rotated daily on the site.

A few other things I personally love about playing with Matchbook, include:

  • Their excellent software – with most games powered by Pragmatic Play or Switch Studios.
  • Their dedicated “Jackpots” page - which offers daily and weekly “WowPots” and “Mega Moolah” promos.
  • Their competitive cash out times – with a three-hour average waiting time reported by real players.

What to look for if you’re serious about chasing the best payouts at online casinos in the UK

BetMGM UK, Bwin and Matchbook all have their merits, as well as their inevitable downsides – and you’ll find a similar story if you decide to go out shopping around for the UK’s best payout online casinos elsewhere.

In my book, the best casino all-rounders are always those that offer the following:

Fair and generous RTP

For those of you unawares, RTP – short for “Return to Player” – refers to the percentage of your initial bets that’s likely to be returned to you over time when playing at any one casino game. So, obviously, higher equals better.

I’d argue an RTP of 85% or more is fair on slots games, while an RTP of 95% plus is generous. So, when comparing the best payout online casinos in the UK, be on the lookout for:

  • Competitive RTP numbers.
  • Large concentrations of high RTP slots games.
  • Tricky bonus T&Cs – which might sometimes limit you to playing low RTP games only.

Fast, hassle-free withdrawals

Whether you prefer playing at real dealer driven live casinos in the UK or sites that prioritise slots and jackpot style games, you’re always gonna want your withdrawal requests processed with minimum fuss, right?

So, I’d also advise looking out for casinos that:

  • Offer withdrawals within 24 hours or less.
  • Support several trusted payment options.
  • Have positive reviews from past players who’ve been able to cash out promptly.

Naturally, BetMGM, Bwin and Matchbook tick all the right boxes here.

Exciting jackpots and promotions

Last but not least, keeping your eyes peeled for the best UK casino bonuses is a great way to separate the wheat from the chaff when comparing online casinos.

As we’ve seen already, BetMGM, Bwin and Matchbook all offer bonus spins promos to newbies and ultra competitive jackpots and tournaments thereafter. But I’d also suggest being on the lookout for:

  • VIP programs and repeat bonuses.
  • Social media promo code drops.
  • Slots bonuses that are compatible with high RTP games.

Conclusion – chase the best payouts at online casinos in the UK with BetMGM, Bwin and Matchbook today

Whether you’re on the hunt for UK casinos that’ll process withdrawal requests like lightning, sites that offer incredible game selections stuffed with high RTP games, or brands that run regular jackpot promos with six and seven figure top prizes, look no further than my three favourite UK casinos.

From where I’m standing, BetMGM is best in Britain for RTP, Bwin is ideal if instant withdrawals are top priority, and Matchbook’s super frequent jackpot promos are pretty much unrivalled in the industry.
