How We Rank Online Casino Sites

There are lots of different and complex ways in which we analyse the best online casino sites, but there are a few key areas which are among the most important:

  • Bonuses and Promotions – If the casino has great special offers with realistic wagering requirements, it moves up our list.
  • Online Casino Games – A wide and varied selection of games is the basis of any top casino.
  • Safety and Security – Your safety is our number one priority. Only 100% trustworthy casinos make our list.
  • Deposit/Withdrawal Methods – Quick and easy transactions earn the casinos extra points in our reviews.
  • Payout – What kind of payout can you find on the biggest games and jackpot slots? This is all considered by our experts.
  • Mobile/Apps – Particularly relevant to new betting sites, the best casino mobile apps are tested, and add to the score if they perform well.
  • Software Provider – The providers of the casinos’ games has a major impact on your experience.

How to Choose a Casino Site

Check our reviews/recommendations

One of the best ways to find a great casino is simply to look at our list of Mansion Bet casino sites. Our experts have already done the hard work, sorting through hundreds of different websites to create a bespoke list for you, highlighting the best new betting sites and top traditional casinos.

Find availability in your country

There’s nothing worse than finding a site you really want to join, then realising it’s not available in your country. Before you get invested in a site, make sure you’re able to play on it legally.

One quick way to do this is to check out the online casino sites recommended on this page, which are all suitable for UK players. And don’t forget that a VPN can always be useful, for your personal privacy and security.

Locate the best bonuses

A big bonus doesn’t necessarily mean a good bonus. If the wagering requirements are ridiculous, you’ll never convert bonus funds into real, withdrawable cash. Our experts recommend looking for bonuses where the T&Cs are stated clearly, with low wagering requirements and no confusing language.

Consider deposit methods

If you only ever make deposits and withdrawals using your debit card, you can probably play at most betting sites in the UK with no issues. But if you like to use a variety of payment methods like Skrill, PayPal, Apple Pay and so on, choose a site which makes it easy for you to do so. There are even many online casino sites which accept bitcoin and other cryptocurrencies.

Choose games you want to play

It might sound obvious, but ensure you select an online casino site which has your favourite games. Don’t get swayed by a lucrative bonus if there’s nothing there you actually want to play. For example, if you like games from NetEnt or Microgaming, choose a casino from our list which specialises in them.

Prioritise quick withdrawals

If you hit a big win, chances are you’re going to want to enjoy that cash. It can be really frustrating to spend days or even weeks arguing with an online casino because they’re blocking your withdrawal.

We’ve hand-tested all of the Mansion casino sites, so you can sign up to them knowing we’ve already processed successful withdrawals in good time.

Factor in customer support

From time to time, you’re bound to run into a few issues when you play at any online betting site in the UK or elsewhere. When this happens, it’s important that you have customer support available which you can rely on.

Our preference is always for live chat, as it’s a quick and easy way to get in touch and get an instant reply. Look out for 24/7 live chat as well as phone support, then test them out with a few questions to see how responsive they are.

Think about the software provider 

Many online casino sites have a single software provider for all of their titles. Others use a plethora of providers to create a very varied library of games. Both approaches are perfectly fine, but make sure you know which service provider you like the most. This will help guide you towards the most suitable online casino sites for you specifically.

If you’ve never noticed which service provider you like, choose a couple of your favourite casino titles and see who makes them. This is a solid starting point. And you can then check the provider’s credentials to make sure they have a reliable reputation in the industry. There are tonnes to choose form including Microgaming, NetEnt, Play’n GO, Pragmatic Play, Rival Slots, and dozens more.

Think about mobile gaming

How important mobile gaming is will depend on your personal preference. We’ve found that many players now enjoy playing casino games on their mobile either exclusively, or split between mobile and desktop.

If mobile gaming is big on your agenda, look out for the Mansion recommended casino sites which offer mobile apps. Or even those which deliver a smooth mobile browser experience for players.
