Online Casino Bonus Codes: What are they?

Have you ever been shopping online and entered a promo code to get a 20% discount? Perhaps you’ve done this at Amazon or an independent UK store? Well, an online casino bonus code is the same kind of thing. You enter a short promo code made up of letters and/or numbers and get access to a special promotion. However, instead of a 20% discount, you’re more likely to unlock a casino bonus. This can be a no deposit bonus, free spins bonus or something else.

How do I use Online Casino Bonus Codes?

Unlocking casino bonus offers is relatively straightforward. However, you would be surprised by how many players make a mistake or typo when entering them. That’s why we’ve made the process even easier. As well as displaying the no deposit bonus code, for example, we also go one step further. By clicking on the casino bonus code itself, you will copy it. Then, when it comes time to enter that casino bonus code, you can simply paste it straight in. Simple!

So, the main thing to remember here is to always copy and paste the bonus code. Then, the only other potentially tricky bit is knowing where to enter the bonus code. This can be on a registration page, in the cashier or directly onto a casino’s promotion page.

However, GamblingAuthority has again streamlined this process to make it foolproof. Simply copy the bonus code and head straight to the casino via the ‘Play’ button. Follow the onscreen instructions and it’ll be obvious when you need to enter the bonus code. You’re welcome!

Where can I find Casino Bonus Codes and Deposit Offers? 🔍

You can find exclusive bonus codes all over. However, you’ll soon find out that barely any of them work, which is super frustrating – and a waste of time. At GamblingAuthority, we personally check each bonus code to ensure that it’s working correctly. And, as we get them directly from the UK online casino in question, they are guaranteed to work. So, by far the best place to find new casino bonus codes is right here. Check out the list above, for example.

No Deposit Bonus Codes for New players in the UK

The ideal time to find a casino promo code is before signing up at an online gambling site. That’s because most promo codes are created for sign-up offers and casino welcome bonuses. We’ll cover the main types of casino bonus code deals below, but for now, simply know that new customers will receive the lion’s share of exclusive offers. And, as we explained above, using a casino bonus code as a new customer couldn’t be easier – just copy and paste them.

No Deposit Bonus Codes for Existing Players in the UK

Existing customers at UK casinos won’t have as many bonus code opportunities. Instead, existing casino players are more likely to make a minimum deposit to trigger an offer. In fact, some of the best online casinos have done away with the need for a bonus code entirely. However, if you sign up for marketing emails, you may be given an exclusive casino bonus code. Alternatively, some online casinos will display them on their promotions page.

How GamblingAuthority reviews the Best Casino Bonus Codes

Our independent reviews of new casinos and established ones assess the bonus money offers. So, if a casino bonus code is required, you’ll be the first to know about it. However, there are many other considerations to take into account. Here are our main review criteria for UK casinos:

👍 Welcome Bonuses

The welcome bonus offer is critical when reviewing a UK online casino. Different casinos attract players in different ways. This can be a free bonus on sign-up, 100% match deposit bonus and/or free spins for top slots. Then, we need to assess the wagering requirements…

👍 Wagering Requirements

If the wagering requirements are too high, it can really sour a deposit casino bonus. Therefore, we want to see wagering requirements kept under the industry standard of 35 times the bonus money. Any casino deals that lump in the deposit amount too are a step too far for our tastes.

👍 Other Casino Bonuses

Once the fun and games of the welcome deal are over, there needs to be plenty more of where that came from. Therefore, we pay special attention to the promotions page. We want to see lots of seasonal promotions as well as lots of promo codes to trigger regular reload bonuses.

👍 Casino Games

Deposit bonuses and free spins wouldn't be all that without the games to back them up. So, we look for high-quality titles from the top game providers. We're talking Evolution Gaming, Microgaming, Big Time Gaming, Play'n GO, Playtech, Yggdrasil and plenty more besides.

👍 Payment Method

UK casino players expect a wide variety of possible payment method options. This includes bank wire transfers, debit cards and some of the best eWallets available. So, we want to see options for deposits and withdrawals via PayPal casinos, Skrill casinos, Neteller casinos, Trustly casinos and many others.

👍 Customer Support

If something goes wrong, you need round-the-clock customer support. What if your bonus code doesn't work, for example? That's why we always test out the customer support team. We want to assess their response times, friendliness and overall casino bonus knowledge.

👍 Licensed Casinos

Last but not least, we want to see a UK Gambling Commission license in place. The UKGC leads the world in providing a safe environment for UK players. And they help resolve any disputes in an amicable fashion. So, not having a UKGC license is a major red flag for us.

Other Considerations when looking for Casino Bonus Codes 🤔

There are a few things to bear in mind when looking for a deposit or no deposit bonus code. Chief amongst these are any wagering requirements. You’ll want a deal with 35 times the bonus amount or less. And ideally, any deposit required should not also be included in those wagering requirements.

Other things to keep an eye on are the minimum deposit amount, eligible casino games restrictions and max cashout limits. There’s more on these things below.

Types of Casino Bonus Codes for UK players

Whether or not you need to use your own money to trigger a bonus code promotion is down to the deal in question. But all of the typical casino bonuses laid out below definitely require a bonus code. So, here, we’ve laid out the most popular types of bonus code casino promotions:

❇️ Welcome Bonus Codes

An online casino welcome bonus is the most common type of promo code deal. Normally, there will be more than one chance to snag welcome bonus money and free spins or bonus spins. Just note that you might have to enter a bonus code for each part of the welcome bonus.

❇️ No Deposit Bonus Codes

No deposit promotions are super popular with UK players. They are available either just for registering a new account at UK casino sites or occasionally as one-offs later on. They usually comprise a small amount of bonus money or free spins for some of the best casino slots.

❇️ Free Spins Bonus Codes

Casino free spins can arrive in your account at any point. They're available as sign-up bonuses, no deposit bonuses, welcome bonuses, or when new games are released, for example. Just note that your free spin bonus winnings will normally be subject to wagering requirements.

❇️ Live Casino Bonus Codes

For those who want to experience Las Vegas from the comfort of their own home, look no further. Live casino bonus codes provide players with a small amount of extra bonus money. This can then be used for bets on roulette, blackjack, baccarat, super sic bo, etc. Nice!

❇️ VIP Casino Bonus Codes

High roller VIP casinos want to keep things exclusive. So, using a casino bonus code system helps keep high rollers happy. Such exclusive bonuses will require significantly large minimum deposit amounts. But the rewards for entering these VIP bonus codes are usually quite massive.

The pros and cons of no deposit bonus codes

With so many different types of bonus codes out there, we decided to focus on the no deposit variety. And to point out the advantages and disadvantages of using them. So, here, in a nutshell, are the main pros and cons of no deposit bonus code offers at UK online casinos:


  • Bonus codes give you access to exclusive online casino promotions
  • They're super quick and easy to copy and paste whenever required
  • Registration and sign-up no deposit bonuses are immensely popular


  • Entering a bonus code is an extra step that can confuse some players
  • Most online casino bonuses do not require the use of a bonus code
  • Minimum deposit, max cashout and other rules may still apply

Games Available when using Casino Bonus Codes

The ways in which you can use bonus cash from a casino bonus code offer vary. Some of the best bonus code deals have no restrictions on games. While others are limited to certain kinds of games or sports betting. So, let’s look at the more popular types of bonus money games:

Slots and Progressive Jackpots 🎰

Online video slots and classic fruit machines are the two most popular recipients of bonus code offers. Sometimes, the deposit bonuses and free spins are limited to one or two slot titles. Other times, a casino bonus code can be used on any slot, including progressive jackpot slots.

Table Games and Poker 🃏

Video versions of the classic table games such roulette, blackjack and baccarat, as well as video poker, are commonly part of free casino bonus deals. However, the bonus terms may severely restrict their use for completing any wagering requirements. Check the terms for more info.

Live Casino Games 🤵

Live dealer games are not included in the offers of many casinos. However, some go the opposite way and offer specific bonus code deals just for live casino games. So, be sure to look for a real cash bonus offer for your favourite live games. Some casinos offer free cash bonuses.

Sports Betting 🏇🏾

Sometimes casino bonus codes are required to unlock free bets and other sportsbook bonuses. However, this is far more likely at dedicated sports betting sites than those combined with an online casino. You can find out more about the latter by reading our online casino reviews.
