4. NetBet

NetBet Casino's bonus code is an interesting one, as it contains heaps of bonus spins. By depositing £10 or more and using the code NBWELCOME500, you can claim up to 500 spins.

However, you get the spins in parts. You receive 50 bonus spins on the day you make your first deposit and NetBet credits the rest of the spins in batches of 25 over the next six days.

The wagering requirement on the spin winnings is 40x, which is slightly higher than the industry average of 35x.

5. BritainBet

BritainBet Casino's bonus code BB200 makes you eligible for a first-deposit bonus you otherwise wouldn't get.

With the code, you can claim a 100% match bonus of up to £200, plus 20 bonus spins. The minimum deposit to claim the offer is only £10, which is a fair condition.

The only downside here is the rather high wagering requirement of 50x on both bonus and spin winnings.

How We Rate Bonuses That Require Bonus Codes

We evaluate bonuses that require a bonus code just as we review all casino bonus offers; we determine what kind of bonus you get by using the code and what conditions come with the deal.

If the bonus obtained with the code is good, its terms are fair, and the rules are clear, we can usually recommend it. If the bonus terms are unclear or otherwise too demanding, we will inform you about these as well, without sugar-coating.

However, bonuses and bonus codes are not the only criteria on which we base our reviews on Bojoko. We also consider all factors that affect your experience at the casino. These factors include, among other things, the quality of customer service, the number of games, payment methods, and security.

This is how we can build trustworthy and reliable reviews of British casinos and their bonuses.

Excellent bonus in all ways possible
Good bonus and/or good terms
An average offer, not good, not bad, nothing special
The bonus is small and/or has heavy wagering requirements
No bonus at all, or the bonus terms are very bad

What Is a Casino Bonus Code?

An illustration of a bonus code field

A bonus code is often a short combination of letters and/or numbers that casinos typically offer for especially new players.

When you use a casino bonus code, you can get a bonus that's reserved only for those using the code.

When you enter the bonus code either during registration or when making a deposit, you receive a casino bonus that wouldn't be available otherwise.

With a code, you can get all kinds of bonuses, such as welcome bonuses, deposit bonuses, free spins, and cashback.

Sometimes bonus codes are exclusive, meaning that you can only obtain them in certain ways, like through promotional emails or selected partner sites.

No Deposit Casino Bonus Codes

No-deposit casino bonus codes are like normal bonus codes, but the bonuses you can get with the code do not require a deposit to be made. In other words, you get a free bonus only by using a bonus code. 

Casino Promo Codes for Existing Customers

When casinos offer promo codes for existing customers, they normally announce the codes in promotional emails and messages.

If you want to make sure you don't miss any offers as an existing customer, it's good to make sure you have given the casino permission to contact you with news of fresh deals.

The most common type of bonus given to existing customers is free spins. You can check here on Bojoko what kind of free spins code existing customers can get right now.

New Casino Bonus Codes

Every now and then, there are new casinos with new and exciting bonus codes. The majority of new casinos choose not to use bonus codes and pick other solutions for promotions, but some casinos still put value on promotional codes. 

The latest casino bonus codes are below. For a wider selection of recently launched casinos, check out our page listing new British casino sites.

Live Casino Bonus Codes

Many online casinos offer live game rooms. Unfortunately, it's very rare to find sites that provide bonus codes, let alone bonuses, specifically targeted at live casino games.

The best live casino websites can house hundreds of live dealer games. Note that not all bonuses can be played directly in live dealer games before wagering it in other games first.

Below, you can check a few examples of bonus codes you can get to casinos with live casino games. 

Casino Bonus Code Bonus Live Games
LuckyNiki NIKI 25 bonus spins 400
PlayMillion FIRST20 100%/£20 290
SlotsMagic MAGIC50 100%/£50 + 50 bonus spins 180

Different Bonuses You Can Get With Promo Codes

A Bojoko styled illustration that reads bonus code

Casino bonuses claimed with a promo code do not differ from other bonuses in terms of what you can receive with the code. Like regular casino offers, bonus codes can grant you access to things such as free spins, deposit bonuses, or cashback.

Below, you can read about some different types of bonuses you can receive by using promo codes.

Deposit Bonus

A deposit bonus is the most common bonus offered by casinos. It can be anything from spins to bonus funds, but it always requires a prior deposit.

Most online casinos offer a deposit bonus without codes, but many brands still use codes to distribute bonuses.

Explore 100% casino welcome bonus deals and even 200% welcome bonus offers offered by casinos on Bojoko. Some may require a promo code to be claimed, but mostly, they're available without.

Reload Bonus

A reload bonus is a deposit bonus that you can receive for deposits other than your first one.

Using a bonus code is perhaps a bit more common with reload bonuses than with welcome and deposit bonuses. Casinos typically let you know about the availability of these codes in their newsletters, so make sure you accept emails from them.

Check out UK casinos with top reload bonuses.

Free Spins

Free spins obtained with a promo code are quite a common way for online casinos to attract players. Free spins redeemed with a code can also be wager-free, but this varies between casinos, as do bonus terms in general.

Have a look at UK free spins casinos here on Bojoko.

No Deposit Offers

No-deposit offers are quite a rare treat at online casinos, and even fewer no-deposit bonuses can be redeemed using a code. However, this is not an unheard-of deal. It is good to keep an eye on new casinos, as such promotions are more likely with them.

Our UK no deposit casino page lists all brands where you can find bonuses without a deposit requirement.

Exclusive Bonuses

Exclusive bonuses are a particularly good example of bonuses that can be claimed with a code, as codes allow casinos to limit the target audience very precisely.

Exclusive bonuses can be restricted to a specific player group or be extremely targeted otherwise, even to individual players.

Bojoko aims to provide its readers with exclusive bonuses and casino codes that are not available elsewhere.

Joonas Karhu, the CEO of Bojoko

Casinos most often offer exclusive bonuses for use by affiliate sites. These bonuses cannot be obtained elsewhere, only through a specific affiliate.

See all exclusive casino codes and other offers you can get via Bojoko.

How To Use a Bonus Code?

Using a bonus code can often be slightly different between online casinos, but usually, it's still very easy. Here are the most commonly used steps for using a bonus code:

1. Obtain a bonus code.

A guide image step 1 of how to use casino bonus codes

To start using a bonus code, you first need to find one. You can check the list of bonus codes on this page.

Always check that the code is valid, as many have expiration dates. Pay attention to the minimum deposit limit and other possible conditions for using the code.

2. Type in the code when you register or deposit.

A guide image step 2 of how to use casino bonus codes

Depending on the casino, you might need to type in the code when you sign up or make a deposit.

If a code is required upon registration, the sign-up form should have a reserved field for it.

Make sure you write the code exactly as it appears on the promotion.

3. Claim the bonus.

A guide image step 3 of how to use casino bonus codes

If the bonus was a no-deposit offer, you should now be able to enjoy the bonus you claimed with a code.

If the code is activated by depositing, follow the cashier's instructions to complete the transaction. The bonus should then be added to your account, and you can start having fun with it.

In case you did not receive the bonus despite using the code, check that you:

  • Used a valid code
  • Typed the code correctly
  • Deposited a sum that's eligible for the bonus

Contact the casino's customer support if you encounter any problems, they're able to help you out and see what went wrong. Additionally, they might be able to manually activate the bonus to your account.

Game Specific Bonus Codes

Logo of Starburst online slot game

Game-specific bonus codes are not very common these days. Instead, online casinos typically offer a code that grants a bonus, which you can then use on any game permitted by the casino's bonus terms.

However, some bonuses redeemed with a code may include free or bonus spins. These spins are often restricted to a single game, which is specified in the promotion.

Usually, the games you can get spins on include popular titles like:

Game Provider Specific Bonus Codes

Game provider-specific bonus codes are not really a thing, as bonus codes typically allow you to play most games offered by the casinos. Some online casinos may even have multiple dozens of game providers.

Of course, games from certain providers tend to be more prominent in bonus offers than others. Brand-new game providers are rarely seen in this context, and typically, the games come from providers that already have built a good reputation among players.

For example, you can often get bonus codes for spins on these providers' games:

Bonus Codes for Special Occasions

An illustration of Bojoko coins, bells and cherries bursting out of a present box

Casinos may mark a special occasion by offering players a special code. These occasions may happen when casinos celebrate their birthdays or if there's a notable event, such as major sports games.

These bonus codes are typically available only for a limited time, so if you miss them, they're gone for good or until the event takes place again. Note that in recurring events, the bonus codes are usually different from those offered last time.

Seasonal Promotions

Seasonal promotions on online casinos are limited-time offers that are available during globally celebrated events, like Easter, Christmas and New Year's, and around Valentine's Day and St. Patrick's Day.

Typical seasonal promotions start well before the day or time they're celebrated. For example, Christmas promotions can start as early as the beginning of December.

Birthday Bonuses

Birthdays, whether yours or the casino's, are always good reasons to expect some special bonus codes to drop.

These days, it seems that only long-standing casino brands tend to celebrate the day that marks another year in the books. Luckily, many more casinos share some extra bonus goodies and codes for players on their big day.

See casinos with birthday bonus deals and how to get them.


Casino bonus codes are typically codes you need to claim a casino bonus. A typical bonus code is short and can consist of letters or letters and numbers.

Casino bonus codes are normally for one-time use only, meaning that you can use a certain bonus code only once in an online casino.

Yes, not all casinos require using a code to get bonuses.

No deposit bonus codes are used to get bonuses that don't require a deposit. In these cases, you only need to enter the bonus code to a casino to receive a bonus.

To use a casino coupon code, you need to either enter the code when you register a new account or when you make a deposit.

Casinos usually provide instructions on how and when to use any of their codes, and this information is also included in Bojoko's casino reviews.

Yes, some casinos can share new bonus codes for existing players. Be sure to accept the casino's promotional emails and messages to stay updated for when new codes get released.
