Best Online Casino

Right, let’s get to it. You want the “best of the best of online casinos”. That’s what you’re here.

And we don’t blame you. It’s why we have a list of 10 on our Best Casinos page. But rather than repeat what we said in our The Best Alternatives sites for King Casino, we’ll show you what the other five have to offer. After all, they’re 5 of the best online casinos in the UK.

What makes an online casino the best in its field? Here are some general factors to consider:


Playability and safety – The UK Gambling Commission plays an active role in ensuring safety on all online casinos in the UK. If a casino doesn’t have a license from them, consider it unsafe. The good thing is we don’t have any of those on this site so you can rest easy
An appealing site – not all online casino sites are created equal, but many share similar themes (playful, bright and colorful, dark and minimal, or anything in between). Whatever you choose is down to preference, but easy navigation and page load speed are super important no matter what colors the site has. Too slow? No, go!
Withdrawals and deposits – how quick are they? What is the minimum and maximum for each? What payment methods do they offer? Make sure it works for you because it’s your money at the end of the day.

Now, how about those impressive and most popular online slots and casinos?

MansionBet Casino


mansionbet casino

MansionBet Casino was launched in 2018 as a separate arm of the Mansion franchise.

It offers 24-hour support, over 200 games, and a deposit bonus with additional spins. But what does it look? Well, it’s very similar to Mansion Casino with its black and red color scheme. The MansionBet sportsbook takes precedence, but the user experience is paramount here with an intuitive navigation system.

The games collection isn’t as comprehensive as other casinos, but it’s quality over quantity. Here’s a brief selection:

  • Age of Gods
  • Premium American Roulette
  • Blackjack Switch
  • Hall of Gods
  • Scudamore’s Super Stakes

Grosvenor Casino

grosvenor casino

You will almost certainly have heard of Grosvenor Casino. The “bricks and mortar” casino was founded in 1970, but the online variant started way back in 2007. But how does the old behemoth compare on the internet?

The online casino provides 16-hour customer support through a multitude of channels, 500+ games, and a high deposit with low wagering requirements.

As the offline casino came first, Grosvenor has used all their prestige and branding for the online version and made it look very bespoke and, if we do say so, quite posh. But then posh folk have a lot of money to spend, so that makes sense.

Games wise, here are 5 of them:

  • Mega Moolah
  • Mega Fortune
  • Rainbow Riches
  • Starburst
  • Extra Chilli

Genesis Casino

Genesis Casino started in 2018, aiming to take the online casino world by storm. The casino prides itself on “total transparency” amongst other things. There’s also a mobile-focused experience here which is essential for a new casino.

Genesis offers an 18-hour support team, helpful FAQs, a welcome bonus including free spins on Starburst, and 1,300+ slot games, live dealer games, and table classics.

Thanks to its spacey theme, the site looks incredible. A purple livery, superb navigation, and minimal clicking to get where you want – what’s not to love? Also, the game filters are plentiful and useful.

Here are some great games on offer:

  • Immersive Roulette Live
  • Gonzo’s Quest
  • Playboy Online Slot
  • Jumanji
  • Dream Catcher

Playgrand Slots

grand slot

PlayGrand launched in 2015, so it’s by no means new, but the sophisticated look has stood the test of time.

The casino offers 24-hour support, over 1,300 games, and a fantastic welcome offer, including bonus spins.

Navigation is a breeze with categories for new games, slots games, top games, and game types. There are also filtering options to narrow down your choices by provider, popularity, and order them alphabetically.

  • Avalon
  • Reel Rush
  • Twin Spin
  • Hall of Gods
  • Book of Dead


winomania casino

Winomania casino review

And finally, we have WinOMania to complete the 5. Another online casino baby launched in 2018, WinOMania calls itself a casino that “aims to provide players with wholesome, secure and invigorating gaming experience.”

To do this, it provides a robust support team and an intuitive interface. The welcome offer is pretty decent, and there are a handful of games including progressive jackpot slots.

WinOMania’s site isn’t as eye-catching as the others, but it makes up for it with top-notch navigation – smooth and speedy – it offers all the top payment methods for withdrawals and deposits.

Want some games to play on WinOMania? Try these:

  • Wheel of Luck
  • Pyramid Spin
  • Riches of Troy
  • Gold Rush
  • Aztec Gold

Set a budget before you start and never try to win back what you’ve lost

Find out what the wagering requirements are. It is especially important because it can affect how you play and what you pay. In a nutshell, wagering is where you play a certain number of times, depending on how much you deposit and what their wagering multiplier is. They can range from no wagering at all, to around 5x-20x, or up to 50x or 60x. If you deposit £100, that could be anything from £500 to £6,000 you must spend before you can get your winnings. Most casinos have these requirements, so visit Online Casino World and make sure you know what you’re getting into before you take the plunge.

Money Management Tips

Discipline is not only a significant part of being a successful gambler but probably the most important element of money management. You must set loss limits and win goals. Example: When losing half your session bankroll (loss limits) you walk, and when doubling your money (win goals), consider doing the same.
