If you are looking for online casino offers, along with your online betting, then look no further.

The internet is stacked full of casino sign up bonuses and promises to win big. Therefore, it can be hard to know where to put your money and which bookmakers you can trust.

So, to help ensure that your free online casino games experience is genuine and enjoyable, we have put together a list of trustworthy sites.

Each site that we’ve featured offers a free casino bonus and has earned its place here by passing our tests.

What is on offer

Casino bonuses may play a part in making your decision as to which site you choose to use, however, there is a lot more to it than that.

An online casino with barely any choice, or a very small range of free casino games, would get boring quickly.

Therefore, one of the things we look for when picking bookmakers to feature on our list is a good variety of online slots, games and fun activities.

Every site we have chosen has a good number of casino games, meaning that you can be safe in the knowledge that you’re getting your money’s worth. As well as this, it means you will have plenty of options to spend your free casino bonus on!


It is good to know when depositing your hard-earned cash that the casino bonus and any winnings you make can definitely be funded by the site.

To ensure that your casino experience is as risk-free as possible we have selected only reputable, established bookmakers. For example, Bet 365 and Ladbrokes, who are strong contenders for the best online casino UK.

A UK cash bonus is great, but if it is a hassle to cash out your winnings at the end, it may not have been worth the trouble. To help you avoid this sticky situation, we went through the pay-out process to ensure that it all went smoothly meaning that you have nothing to worry about and can safely play casino games for free!

Picking a site

It is extremely easy to simply see a big casino bonus and sign up straight away, but there are plenty of things to consider before handing in your card details and rushing into free slot games.

It is important to make sure that the site you pick is right for you. Aside from the online casino bonus, be sure to check that there are live chat options, in case you need support at any point.

Along with this, consider what features are right for you. If you are more interested in a social online casino with a sense of community, then you may want to look for a site with chat boxes or user information on winners. Winner Casino offers features such as this.

The best way to pick the perfect casino for you is to read through our list of casino bonus offers and then to do a bit of reading on the ones that stand out to you before deciding and jumping into your free online slots.
