The latest casino codes

They say that life is all about choices.

When it comes to casino codes, there is no shortage of options. But how do you know you’re getting the best deal?

As you browse through our list of free bonus codes above, you will notice that they share some common attributes. First, only the most reputable of casinos have been selected — these are fully licensed, well established, and rigorously regulated. The upshot is that you can register for a new player account with complete peace of mind.

Second, we have cherry-picked the bonuses that deliver the most agreeable terms and conditions. It’s not all about the promise of huge deposit bonuses — you should also consider how many free spins you’ll receive, what the wagering requirements are, and how long you will get to satisfy those wagering demands.

The key to our casino bonus codes is that they deliver only the finest offers for our followers — with no exceptions.

How to use a no deposit bonus code

There are two distinct types of casino welcome bonus: deposit and no deposit bonuses.

Generally speaking, a ‘deposit bonus’ means that you will have to make a deposit in order to gain the bonus — i.e. you’ll be handed a 100% match of your first deposit up to, say, £100. With a ‘no deposit bonus’, you won’t have to make a deposit/register in order to claim a welcome offer, be it free spins, risk-free bet credits, and so on.

The same two types of bonus codes are available for online casinos. The standard deposit bonus codes can be seen in our library above and typically, you will be asked to enter these as you go through the account registration process.
As far as your no deposit bonus code is concerned, the same principles are true — although, of course, you don’t need to make a deposit in order to trigger the offer.

Instead, you will be asked to enter some necessary personal information along with your bonus code. Don’t worry — this is kept perfectly safe as we only recommend the most professional of casino sites. Once submitted, your free spins will be available to use for a specific timeframe.

Free spin online casino codes

Arguably, the most popular of the online casino bonus codes UK available are those linked to no deposit offers.

A free spin online casino code feels like exactly that: free money. This is not wholly accurate because you need to actually enjoy a winning spin or two from your collection, and then you will need to clear any wagering requirements that are in place before withdrawing any of your winnings.

There is nothing completely ‘free’ about free spins, but when you consider the rewards available — with no risk to your bankroll — it is no wonder that free spins bonus codes are so eagerly sought.

As ever, the process for using our free spins bonus codes remains as easy as 1-2-3:

  • Click on the code to copy it to your device
  • Register for a new player account at the relevant casino site
  • Enter your bonus code when prompted to trigger the offer

Best online casino bonus codes

It’s a bold claim to say that you have the very best online casino bonus codes at your disposal, but we really do mean it.

A good casino will naturally add desirability to their casino bonus code, quite simply because this is a gaming site that you will return to time after time. Some players like to ‘bonus hop’, registering with a catalogue of casinos in order to take advantage of their welcome package.

If that sounds familiar, great — there is no problem with that — but it is worth knowing that we have chosen the online casinos featured on this site purely for the quality of the user experience that they deliver.

You probably know by now that the libraries of NetEnt, Microgaming, Evolution and co. are where the best of the action lies. These casinos are set aside by the website or app’s ease of use, the responsiveness of the customer support, the quality of ongoing bonuses, and the promotions that they offer.

Put all of those things into the melting pot and you come up with a selection of the best online casinos available to UK players — that’s why we consider our bonus codes to be the best around.

Licensed UK casinos

Prior to recommending a casino (or not), one of the key factors we look at is whether they are licensed and regulated appropriately.

Thankfully, the UK Gambling Commission is one of the most robust authorities in the industry. So, when a casino site carries their approval after being awarded a licence, you can rest assured that you’re in a good place.

The Commission performs a number of crucial acts to safeguard players. It performs a background check on all of the registered owners of online casinos to make sure they are competent and financially soluble. This gives players the confidence of knowing that a catastrophic event — such as insolvency — is less likely to happen.

If a casino is approved by the UK Gambling Commission, as are all of the options listed above, you know you are in the safest hands.
