Exact steps may vary slightly at each online casino, but generally you need to:

  1. Follow our link: This will take you to the dedicated page – especially important in the case of an exclusive offer or bonus code.
  2. Register your details: This should not take more than a few minutes of your time and you will have to supply basic information, such as your name and date of birth, and create an account/password.
  3. Deposit: Most casinos’ welcome offer comes in the form of a deposit match and/or free spins. If required then you can make a first deposit, with £10 generally the minimum amount.
  4. Get playing: Whether you are in the mood for online slots or classic table games, the casinos we showcase at Slotsia will have you covered – enjoy playing with your bonus funds!

Exclusive Casino Bonus Codes at Slotsia

In a similar style to Wowcher or Groupon, some UK casino bonuses will also reward you for entering a unique code. Exclusive casino bonus codes are just that – exclusive. Therefore, we know where to find them and it makes sense to let us collate them in one place for you so that you can decide which calls out.

Once you have the code, you will need to enter it; this can be done either manually or by clicking the link on our page. Importantly, some of these codes can be used by returning players, meaning that you can get extra funds despite already having an account – always check the terms and conditions to be safe, though.

Different Types of Casino Bonus

As we have consistently mentioned on this page so far, there are multiple types of casino bonuses that can be claimed. Whatever your taste or budget, you are sure to find something suitable on Slotsia – and each casino comes with an in-depth review so that you know what you are getting into.

Below we will look at some of the most common online casino bonuses that you will encounter.

Welcome bonus

The most popular type of introductory offer to a casino, you will generally get a boost to your first deposit or deposits up to a certain amount. The standard is 100%, so doubling your payment, but it is not unheard of to be even higher. 

Free spins

As well as the above, free spins are also routinely offered; you can expect to get 50 spins or more. It will usually be specified in the offer which game you can use these on, though several titles are more common with Starburst a perennial favourite. Maximum stake amounts may also be tied to this type of offer.

No deposit bonus

Not all casino bonuses require an up-front payment, and if you are looking for the chance to play for real money without even providing any banking details then no deposit bonuses are likely to be your best bet. Winnings will be capped, though, but if you have time on your hands then getting something for nothing is a distinct possibility.

No wagering bonus

Casino bonuses without turnover requirements are pretty rare but also potentially lucrative. Basically, what you win you keep without having to risk – or wager – the funds a certain number of times.

Cashback bonus

UK online casinos that offer cashback are becoming increasingly common and this will usually be on top of any welcome bonus that you receive. Cashback here refers to a certain percentage of any losses in a specified time period that will be returned to your account balance.
