Slotsia’s Guide to Bonus Codes
Online casino bonus codes are generally either a series of letters or numbers or both, or a simple phrase that is linked to the nature of the bonus. For example, if one such offer was for a Starburst and offered 50 free spins on your first deposit, the casino promo code used may be something like: ‘STARBURST50‘
As well as bonus spins, you can enter your code to claim cash bonuses, bonus money, free spins no wagering and reload bonuses. Depending on the bonus you get, you could play slots, table games and even live games with it!
If you have ever used discount coupons or vouchers when shopping online, then using Slotsia’s bonus codes are very similar and equally easy to use. Here are the steps:
- Follow the link and register your details with one of our recommended online casinos to create an account;
- Head over to the banking or account section of your UK casino;
- Check the instructions or terms to see where and when you can enter your promotional code;
- When you enter it, make sure it’s correct. Double-check here for any hyphens, capitalisation and spelling of words to ensure you enter the it accurately. An example of a deposit code offer could be something like: ‘SLOTSIA100SPINS‘;
- If you have to make a deposit, ensure you deposit at least the minimum amount required to activate the bonus and that you use a payment method that’s not excluded;
- Click redeem. The offer should then be activated and your bonus will be available!
Casinos with welcome packages offer multiple bonuses with a code required on each deposit. This means you could get rewarded up to your 3rd, 4th or 5th deposit!
We know that casino codes are highly-valued by casino players, especially no deposit bonus codes. The great news is that it is easy to find some of the very best offers right here at Slotsia!
But, when it comes to choosing, how do you know a good casino promotion from a bad one? Here are some of the things you can check before redeeming an offer. Because many different types of casinos have these offers, it’s preferable to choose:
- An offer that gives you flexibility over where you can play, such as by offering you the opportunity to redeem your bonus over a choice of slot games, rather than just one.
- Offers that enable you to play brand new slot games, or established slot games that are very popular.
- Bonuses with a relatively low wagering requirement.
- Ideally, choose an offer with a high win cap and no maximum cash out value on any winnings from the bonus.
- Select an offer where you can redeem an additional bonus on your 2nd deposit, or even additional deposits, such as those in a Welcome Package.
- Find a promotion where you can use a bonus code alongside another offer, such as a deposit bonus so that you can have extra chances to win!
A casino promo code allows you to redeem a bonus that would otherwise be unavailable. On the whole, they are a combination of letters and numbers, as in the example: SLOTSIA99. Think of these codes as unlocking unseen & exclusive offers!
Find your casino code in our list of offers or in the bonus section of our casino reviews at Slotsia. Enter your promotional code, as instructed by the casino, to get your bonus! You usually enter it in the banking or account section of the site.
Have a look at our list of casinos that offer these exclusive deposit code promotions. The list is regularly updated, so you can check back to find out what the best deals are at any particular time.
The main benefit of casino bonus codes is that they are easy to use, easy to apply and give you the chance to redeem a number of bonuses, including cash or free spins, to trial a casino with. Sometimes they can be used in conjunction with a deposit bonus. With a promotional casino code, you can get an exclusive bonus, only available here at Slotsia!
No, you can only sign up and get a new player offer once. Your code is only valid when you’re a new player and will give you a one-time offer. However, you can sign up at several different casinos on our list and use your exclusive promo codes to redeem more offers!
