Casino Bonus Codes in the UK – Best Casino Promo Codes

What Is a Casino Bonus Code?

A casino bonus code is a string of digits or characters, sometimes random or sometimes spelling a word, that can be pasted into a box on a casino’s deposit or promotions page in order to unlock an exclusive reward.

The reward itself can vary substantially, and entering a bonus offer code isn’t necessarily the only stage involved in unlocking the deal.

Types of Casino Bonus Codes in the UK

In UK casinos, players are likely to encounter various different types of these promotions. Codes usually unlock rewards like free spins, free chips or bonus cash. In the following sections, we’ve outlined the different types of bonus offer where a code might be needed.

Welcome Bonus Code

A welcome bonus, or welcome package, is a type of promotion offered only to new customers, and only once. Welcome bonus codes may be required to unlock them in some cases, often as well as a first deposit. The reward itself could take any form, from free spins to bonus cash, free bets or bingo tickets.

No Deposit Bonus Codes

No deposit offers are unlocked without the need for any cash to be paid in. This is obviously great for players, but it’s often the case that before you get your no deposit offer, bonus codes are required. These are a great way to try out new platforms and games without having to dip into your bankroll.

Free Spins No Deposit Codes

Who doesn’t love a few free spins!? No deposit free spins allow players to enjoy slot games, and even win real money, despite the fact that they haven’t actually wagered anything. Any bonus winnings from these usually need to be wagered before withdrawal, but they’re a fun, low-risk way to explore new slots and sites.

Matched Deposit Bonus Code

Matched deposit bonuses require players to make a deposit. These are often available to both new and existing customers, so keep an eye open and check your emails for any codes that relate to a matched deposit bonus.

Casino Promo Codes for Existing Customers

Bonus codes for existing players aren’t as common, but they’re worth searching for! A code like these is a way for casinos to reward loyal players and keep them coming back. These are usually entered on the promotions page.

Special Casino Bonus Codes

There are additional ways to get bonus codes beyond the main methods we’ve mentioned above. Casinos issue special bonus codes for a variety of reasons, such as:

• Birthday promo codes: These are offered by casino sites to celebrate your birthday. You will usually get an email containing the bonus code. Think of it as an extra gift!
• Live casino codes: Many players appreciate live casinos, so it’s only fair that promo codes should apply to these too!
• Crypto codes: At crypto-friendly sites, you may receive a bonus code that applies when depositing with Bitcoin, Ethereum, Litecoin or another crypto.
• Exclusive codes: These are often only available through specific loyalty systems or VIP clubs.

How to Use Casino Codes

These codes can be used in different ways, so the steps will vary depending on the type of promo you’re claiming. Below is an overview of how it works at many casinos.

How to Choose the Best Online Codes in the UK

Some codes can be worth more than others, so choose carefully. Here are the main factors that players should take into account:

• Wagering requirements: The higher the wagering requirements, the less valuable the bonus. These stipulate that players must re-wager their winnings a number of times before they can withdraw.
• Time limits: Consider expiry dates and timeframes. If they are tight, be sure to complete the wagering requirements before they expire.
• Game selection: It’s usually the case that a bonus can only be used on specific titles, so check out what these are. If you’re given a choice, go for the highest RTP.
• Payment methods: Some promotions have restrictions on the payment methods that can be used. It’s often the case that certain e-wallets are excluded, and that a debit card is preferred.

Top Tips to Make Bonus Codes Work Harder For You

Using a casino promo code is already a great way to make your bankroll go further, but here are certain hints, tips and methods that can be employed to make the bonus go even further.

• Read T&Cs: Always read the terms and conditions carefully, so that you know exactly what you’re getting.
• Manage your bankroll: Responsible gamblers always watch their bankroll closely, and are careful not to wager what they can’t afford to lose.
• Be strategic: Save your more valuable codes for longer sessions, so that you can get the most out of them.
• Consider RTPs: When you have a choice of how to use your bonus, a high RTP title (over 96%) will give you a better chance of beating the odds.
• Combine your promotions: If possible, stack your promotions. For example, you might be able to claim loyalty rewards points at the same time as a welcome bonus.
• Use no deposit codes first: These are a good way to test out casinos and games to see what you enjoy, before you make a deposit.

Top Reasons to Claim a Casino Bonus Code

For players in the UK, bonus codes for online casinos are a simple yet powerful way to get more out of every deposit and every slots site. Here are some of the main reasons that you should consider claiming:

1. Try new games. Both free spins and bonus money give you a chance to try new games.
2. Explore new sites. Codes let you decide whether you like a slots site, often without having to make a deposit.
3. Extend your sessions. By boosting your bankroll with bonus spins and funds, you can get more out of your sessions.
4. Increase winnings. It’s a game of luck, but more bonus spins and funds means more chances to win!
5. Extra loyalty rewards. Some codes enhance the VIP club or loyalty system, unlocking additional rewards.

Casino Bonusсode: Terms and Conditions

When it comes to online casino promo codes, we can’t overstate the importance of reading the terms and conditions. We know it’s nobody’s idea of fun, but paying attention to the following terms is essential.

Maximum Withdrawal Limits

It’s common for a bonus, whether it requires a promo code or not, to have a maximum withdrawal limit, often referred to as a ‘win cap’ or similar.

For example, if you were to claim a 100% bonus up to £100 plus 50 free spins, there might be a ‘win cap’ of £200. This is your maximum winnings limit. No matter how much you win, you won’t be able to withdraw more than this, even after the wagering requirements.

Game Restrictions

Game restrictions are relevant to bonuses that require codes as well as those that don’t. These state that your rewards can only be used on one game or a selection of games. Restrictions may apply to specific games, or to a whole category of games, such as “cannot be used with jackpot slots” or “must be used in the live casino”.

Using our example of a 100% bonus up to £100 plus 50 free spins, you might be able to spend the bonus funds however you want, but the spins may only be able to be used on Starburst.

Expiry Dates

All bonuses expire, and those which involve casino promo codes are no different, so be sure not to get caught out. Some bonuses will give you a whole month to convert your deposit bonus funds into cash, whereas others might give you a number of hours!

In our example of a 100% bonus up to £100 plus 50 free spins, you might get 7 days from the time that the bonus is issued to complete the wagering.

Wagering Requirements

You may have already come across wagering requirements. These are a big obstacle for many players. Essentially, they make you re-wager your bonus, giving the casino a chance to reclaim much of the value.

Let’s say you get a 100% bonus of £100 plus 50 free spins with 5x wagering on the bonus and 30x on the spins. You would have to re-wager the bonus funds up to a total of £500 (5 x £100 = £500) before you can withdraw. With spins, wagering applies to winnings, so if you won £5 from your spins, you’d have to keep wagering until a total of £60 had been wagered.

Minimum Deposit

When a bonus requires a deposit, there will be a minimum deposit. Anywhere between £5 and £20 is common, but it can depend on both the slots site and the bonus type. When it comes to online casino promo codes, you might need to enter the code at the same time as making the deposit.

If you claim a 100% bonus up to £100 plus 50 free spins with a £20 minimum deposit, you can claim a bonus amount between £20 and £100.

Eligibility

Not all bonuses are available to all players. Often, the most valuable bonuses, such as those which require free bonus codes to be entered, are only available to new customers. Others simply require that the player be 18+ and the holder of a verified account. Others might specifically state that it’s for UK customers only.

For example, a 100% bonus up to £100 plus 50 free spins might be available to “new customers only”, in which case it would have to be your first deposit that unlocked it.

Best Games to Use Your Online Casino Codes On

Players redeeming codes often have a choice of eligible games, whether that’s from a list of slot games, or across the whole casino platform. In the following sections, we’ll discuss the relevant categories of games.

Free Slot Games

Probably one of the best ways to use the bonus you receive is on slots. Slots are fun and engaging, and they tend to have a high RTP, as well as access to big jackpot prizes.

When using free spins on slot games, there will be a pre-set per-spin value, so you won’t need to choose the stake. However, if you’ve got a bonus amount of funds to spend, you might want to set the stake as high as possible, as this can give you a better chance of beating the odds.

The following slots have high RTP rates and are good options for using your bonus offer funds or spins on:

• Mega Joker (NetEnt): This is a super-high RTP game with a retro design and basic gameplay.
• Gates of Olympus (Pragmatic Play): This is one of Pragmatic’s many high-RTP titles, with some fun bonus features.
• Starburst (NetEnt): Often included in bonuses, Starburst is perhaps the best known of all slot games.
• Gonzo’s Quest (NetEnt): A heritage adventure game, Gonzo’s Quest is beloved by players, and with good reason!
• Book of Dead (Play’n GO): Spawning a whole trend of Indiana Jones-like slot games, this is a popular choice for bonuses.

Free Blackjack

Blackjack is a popular table game with a low house edge (which is the same thing as a high RTP). The advantage of video blackjack and other table games is that you can view the RTP, unlike when playing like with a deck of physical cards. Also, there’s an amount of skill involved, which makes them extra-appealing to many players.

Free Roulette

Roulette is a game of many variants. Countries all around the world have different takes on it, but it’s immediately recognisable for its ball-and-wheel format. When claiming bonuses with promo codes, players often place a few chips on the roulette table, as it has the potential to offer substantial returns if you get lucky enough.

There are both live versions and table versions of roulette on just about every casino site. Whilst not exactly a game of skill, there are certain strategies that can benefit savvy players, so you may wish to check these out first.

Video Poker

Video poker is a table game that combines the fast-paced nature of RNG-based slots with traditional poker. Certain versions are compatible with promos, so it’s possible that the casino sites you frequent will allow you to play these using bonus funds.

Live Casino Games

Some casino codes unlock a deposit bonus or bonus funds that can be used in the live casino section of a site. Live casino games take place on a real table with a real dealer, streamed to your device.

For this reason, they appeal strongly to those who appreciate the atmosphere of in-person gambling, and the strategy of a non-RNG game. Live games include baccarat, sic bo, poker, roulette, blackjack and more. Some have lower house edges than others, and we’d recommend prioritising these.

Responsible Gambling

Whether you’re gambling with casino bonus codes or not, responsible gambling is paramount. Gambling is great fun, but only when done safely. When using codes, it can be easy to lose track of things, and to get used to fast-paced gambling without consequences, only to keep up this attitude when it comes to playing with real money.

If you or someone you know needs help, speak to one of the helpful support organisations like GamCare, Gamblers Anonymous or Gordon Moody. Also, check out the safer gambling tools that casinos make available.

Casino Codes – Our Expert Opinion

Online casino bonus codes are essentially vouchers, and, when applied to your casino account, they can be used to unlock a whole host of different casino bonuses, from a matched deposit bonus to a welcome bonus. In fact, some of the biggest casino bonuses around require codes.

Many of the most popular promo codes concern slots. Slots are beloved by a huge number of players, so watch your inbox for slots-related promos, and their corresponding codes. Codes are often found in marketing materials from slots sites, and they’re usually entered either when registering, depositing, or on the promos page.

Fans of slots sites should use the above information to inform their own decisions about which promos are worth claiming.
