What Are Bonus Codes?

In the same way that you might seek out a promotional code for your favourite online retailer in order to get a 10% discount or free delivery, casino bonus codes offer you the chance to get better value at an online casino.

Put simply, casinos give out codes that, when entered, will give a special bonus; this will usually be in the form of free spins or an additional amount on top of your deposit. It really is that straightforward – simply add a short phrase on the right page and you will be rewarded. A common example could look something like this: STARBURST50 for 50 free spins on the classic slot Starburst. Depending on the offer, you won’t even have to necessarily be a new player to avail of such a code; this is in stark contrast to most other bonuses on the market.

Another thing to point out is that casino bonus codes can be utilised on all sorts of game modes, whatever your taste – so make sure you choose wisely from our comprehensive list.

How To Use Online Casino Bonus Codes?

The beauty of bonus codes at online casinos is that, despite being relatively rare, they are extremely easy to take advantage of once you find one. Indeed, once you have done the hard graft in research – or in this case outsourced it to Slotsia – then all that remains to be done from you as a player is a few simple steps.

Find a bonus code that suits your requirements; consider whether you want free spins, a deposit match, or both.
Clicking the relevant link at Slotsia will take you to the casino’s sign-up page where you can enter the code.
Depending on the nature of your offer, you may need to make a deposit. Your bonus will be applied to your account balance and ready to be used.

Pros And Cons Of Using Bonus Codes

Bonus codes are universally seen as brilliant and a great way to get value for money. However, they are not best suited to all players as our table below summarises.

What we like:

  • Codes offer exclusive deals
  • Often include free spins so great for slot players
  • Not just for new players
  • Very easy to claim

What we disliked:

  • Can be hard to find
  • Codes may be time-limited

As shown above, if you are looking to take advantage of a bonus code, the positives greatly outweigh any negatives. Regardless, as with any type of casino offer, it ultimately comes down to each individual, so always compare a code with another type of bonus to see what is best suited to you.

Where To Get Best Casino Bonus Codes?

While it is possible to trawl the hundreds of the UK online casinos that exist to look for bonus codes on your own, we recommend using a comparison site, with Slotsia your best option.

On this page we have compiled all of the offers that we could get our hands on, including some exclusive codes. So, if you want to get one of these offers, simply click the relevant link and enter the code to get started – below are some fantastic offers.
