What Are Casino Promo Codes?

Hunting for casino bonus codes is like searching for special discount codes or gift certificates when shopping online. Some online casinos frown upon such bonus codes and claim that they are overrated; others believe that casino codes bring players more fun and excitement when unlocking exclusive offers.

Just like various casino promotions, casino bonus codes are used to promote new game releases or time-sensitive special offers. They can also be used to attract new players and reward existing ones by giving them special access to limited deals. Therefore, often, you’ll see casino codes in the shape of a password bound to specific promotions such as free spins, a welcome match bonus, reload bonus or a no deposit bonus. For example, the offer can appear as ‘25 free spins on Starburst with code JOHNSLOTS’. You would need to enter this exact passcode to activate your offer; otherwise, it wouldn’t work.

You can also search for referral casino bonus codes or vouchers via various online forums, which can be quite time-consuming. Also, if forums aren’t regularly updated, you’ll be wasting your time just to find invalid promo codes. Therefore we recommend using our up-to-date top list for quick and easy access to the latest casino bonus codes.

Not all bonus codes work for every player. While some casino promo codes can appear on the casinos home or bonus page for everyone to claim, others can be more exclusive. For example, a special code can be sent to the list of the casino’s VIPs only. Also, a special casino promo code can be sent directly to your email or phone number as a birthday gift from the casino. This type of bonus code will be tailored to work exclusively for you.

Types of Casino Codes

There are as many types of codes as there are casino bonuses including welcome bonuses, no deposit bonuses, free spins, no deposit free spins, and reload bonuses. Sometimes it can get slightly confusing to differentiate them, so we’ve got our casino experts to clarify it for you below.

Casino bonuses, free spins, bonus spins and other promotions

Welcome Bonus Codes

This type of bonus is perfect for new players and usually activates upon signing up and making your first deposit. By entering the code provided, you’ll unlock your welcome bonus which can be anything from a 50% to 200% match bonus, to 10 or more free spins, to 20% cashback. For example, they may appear as follows:

  • Deposit £10 & claim 100% up to £100. Use promo code: JOHNSLOTS100*
  • Deposit £10 & claim 25 free spins on Book of Dead. Use promo code: JOHNSLOTS25*
  • Deposit £10 & claim 10% cashback. Use promo code: JOHNSLOTS10*

*Example offers only

You might also come across a casino promo code to use with a no-deposit welcome bonus, which is one of the most sought-after welcome offers by casino players. The reason being, you don’t have to spend your own cash when you start playing, hence the bonus name. Essentially, by using a bonus code to activate the no-deposit offer you can start playing games for free, which is always a good start at an online casino.

These types of welcome bonus codes will almost always be clearly visible on the casino’s home or bonus page for you to use. Failing to enter the code provided may result in you losing the bonus altogether, therefore, you should always check the bonus terms first.

Free Spins Codes

As with the welcome bonus, you can get a mixed bag of rewards with free spin codes as a new or returning player on numerous online slot games. These can be standalone extra free spins, a part of a match bonus offer or even no-wager free spins.

For example, you can get a 100% match bonus with your first deposit and also benefit from free spins on top of the offer in exchange for the bonus code. The no-wager slots bonus codes are especially great for testing out various games. And they are useful for new casino players who want to be able to cash out their wins straight away! These bonus offers could look like this:

  • 100% up to £100 + 50 extra spins on Starburst. To unlock extra spins, use promo code: JOHNSLOTS50*
  • Up to 75 free spins no wagering on Starburst with promo code: JOHNSLOTS75*

*Example offers only

Reload Bonus Codes

Reload bonuses can be beneficial for both first-time players and returning customers. As multi-tiered bonuses, they offer a chance to claim more additional bonuses on your second, third, fourth and sometimes even fifth deposit. These, again, can include a nice mix of match bonuses and free spins.

In most cases, you will not need to enter a bonus code on your first deposit. But you’ll have to use specific codes provided to make the most of the extra bonuses when re-depositing:

  • 1st Deposit: 100% up to 100% + 100 free spins on Starburst*
  • 2nd Deposit: 50% up to 100% + 50 free spins on Starburst or Finn’s Golden Tavern. Use promo code: JSD2*
  • 3rd Deposit: 50% up to 200% + 25 free spins on Book of Dead. Use promo code: JSD3*

*Example offers only

Another way to obtain various reload bonus codes is to join the casino’s mailing list and opt-in to their promotional emails. Or, as a regular player, you can always contact the support team to see if they have any special bonus codes available for you.

How to Find the Best Bonus Codes for Casinos

The trick in finding the best casino codes is knowing what’s hot and what’s not in any offer. Our team of casino experts uses multi-step criteria to determine the best bonuses around.

The first thing you should do is to read the small print carefully. Here you’ll find all the nitty-gritty details about the terms and then will be able to decide whether the bonus suits your playing style and budget.

Our main rule is to never fall for the biggest bonus offer available straight away. Though it happens, the bigger bonus doesn’t always mean a better bonus. Pay attention to wagering requirements, the minimum depositing amount, expiration time scales and which games you can use your bonuses on. Also, check if your spins wins are capped and at what value they come. The bigger the value, the better the bonus.

How to Use Bonus Codes

While each casino offers different bonus codes, the process of using them is almost identical and can usually be completed in 3 short steps:

FAQ Section

Ready for bonus code hunting, but have more questions? Below you’ll find answers to some of the most asked questions about casino bonus codes.

Bonus Code FAQs on blue background

What is a bonus code?

A casino bonus code is your ticket to special promotions, limited offers or exclusive VIP rewards at an online casino. For instance you can unlock exclusive offers and extra bonuses by entering a casino code on registration.

Existing players can also benefit from bonus codes and use them on their favourite games. These can be sent to you via email or a text if you’ve opted into the casino’s mailing list. Other casinos will have them advertised on their homepage for unlocking new and exclusive games, special challenges or tournaments.

Do all casinos offer bonus codes?

No, not all casinos offer bonus codes. Some casinos will give you a straight welcome offer of a match bonus, free spins, cashback or a mix of bonuses which you can claim on your first deposit. Others will want you to use a pre-generated casino promo code to claim a part of the promotional offer, enter competitions or play exclusive games. Every other casino will usually only give bonus codes to reward their VIP players.

Do all casino bonuses need a code?

No. You only need to enter a code to claim your bonus if the casino requires you to do so and provides you with an appropriate code. But you should always check the promotions page or bonus terms in case a special code is needed. Sometimes specific codes might not always be clearly stated within the initial bonus ad.

What do I get with a bonus code?

You get access to special promotions such as free spins, cashback, special tournaments, or prize draws. In some instances, you might be able to unlock new game releases or other exclusive content, but these rewards vary widely from casino to casino.

Do casino codes have wagering requirements?

Casino codes themselves do not carry wagering requirements, but the bonus might, depending on the casino. For example, if the bonus terms state that the winnings from free spins have a 20x wagering requirement, then you’ll have to wager the amount of your bonus 20 times before you can withdraw it. In some cases, your free spins or other bonus might be wager-free, which means you do not have to fulfil any wagering requirements and all the wins are yours to keep.

Do I need to deposit money to use a bonus code?

Not always. No-deposit bonuses, for example, don’t need funds depositing and you can start playing your favourite games virtually for free without having to spend your own money. Otherwise, you’ll need to make the minimum deposit necessary to unlock the promotion.
