What Is an Online Casino Bonus Code?

What is an Online Casino Bonus Code

A casino bonus code is a unique code that automatically activates a bonus. When you activate your online casino bonus code, the casino will reward you with a first-deposit bonus, a welcome package, a no-deposit offer, or an existing player bonus. Sometimes, you’ll find exclusive bonuses at aggregators like KingCasinoBonus UK.

These are the main types of bonuses a casino bonus code can activate:

  • Casino no deposit bonus codes
  • Free spins promo codes
  • Cashback
  • Welcome casino bonus codes
  • Existing player bonuses

Is a casino voucher code or coupon code the same thing?

Online casinos may present their casino bonus code offers with various synonyms like voucher, coupon, or promotional codes.

No deposit and deposit-activated casino promo codes

As you might be familiar from traditional bonus language, there are 2 types of casino bonus codes/promo codes. You can get no deposit casino bonus codes or deposit-based promo codes. Deposit-based casino promo codes work similarly: to redeem this promo code, you must copy and paste it during depositing.

How We Review UK Casinos with Promo Codes for Bonuses

For a trusted and knowledgeable review, our team thoroughly looks into various aspects, noting down the pros and cons for each. Here is our checklist when selecting no deposit casino bonus codes for UK players:

Live Casino Bonus Codes

If slot bonuses aren’t your cup of tea, why not give live casino bonuses a try? You’ll find match-ups, no-wagering, no-deposit bonuses, and more on our full list of live casino bonus codes. Here’s a snapshot:

Compare All Types of UK Promo Codes on Sign-up

We created a special section with some of the best-value UK promo codes available and sorted them by type, along with the pros and cons of each type, what they contain, and a brief explanation.

No Deposit Bonus Codes

A no-deposit bonus code is a type of bonus granted instantly after sign-up based on a unique code. This is the best type of offer that UK punters can come across because it will allow you to play real money games without spending any pounds.

Best Examples

You can find a no-deposit bonus code at MadSlots casino. For now, you don’t have to enter any bonus code, but based on our experience, MadSlots sometimes changes the rules of their bonuses, and you can find it attached to a bonus code. Consider this offer because it will give you 100 free spins to play slots.

Free Spins Promo Codes

With a bonus code, you can activate free spins to play slots. You’ll encounter different types of free spins bonus codes, sometimes without a deposit and sometimes with a required deposit.

Best Examples

The best alternative where you’ll have just free spins after a deposit comes from Winomania. If you deposit 10 pounds and type WINO100, you’ll have 100 fs with 40x wagering requirements, but the beast feature bound to this offer is that you can play Cleopatra, Gold Rush, Wild Eagle and Scratch King.

Bet and Get Bonus Codes

This kind of offer is one of the easiest ones in the industry because all you have to do is deposit a required amount and wager that amount to gain the offer; of course – all of these are eligible after you type the bonus code.

Best Examples

For example, at Rhino.bet, you can type the bonus code casino75 and trigger 75 free spins to play Bonanza. You must deposit and bet a minimum of £25 to activate it fully.

Matched Deposit Bonus Code

Online casino bonus codes usually activate a first deposit offer that matches the percentage of the amount you deposit with bonus funds.

Best Example

The best alternative for a matched offer comes from Pokerstars Casino bonus codes. You must deposit at least £20 and enter the code FIRST200. You’ll have a 100% up to £500 offer that will be worth your time because it comes with a low wagering requirement of just 5 times.

Cashback Promo Codes

Cashback bonus codes are provided to customers when they use their cards to make purchases. Casinos usually do this kind of action to keep their customers loyal.

Of course, there are some rules for getting the cashback, and our recommendation is to read the bonus policy before you engage in such an offer. This bonus code offer will give you a percentage back from your initial deposit.

Best Example

At All British Casino, you’ll encounter a daily cashback offer that will give you 10% of your initial deposit back. There’s no wagering attached to this offer, but you must be aware that the initial deposit must be clean and not attached to a prior offer.

Bonus codes for game providers

Some online casinos run special promo codes limited in games from leading game developers like Playtech, NetEnt or Play’n Go:

  • Best Playtech bonus codes: 100 wager-free spins no wagering on Playtech slots at Pokerstars – on registration.
  • Play the best Barcrest slot, Rainbow Riches, at JeffBet Casino with our exclusive voucher codes.
  • Compare the newest IGT slot additions with 30 no wagering spins Monopoly casino promo code and study their libraries.

Types of UK Casino Bonus Codes for Existing Customers

Promo codes aren’t exclusive to new players, though they are more numerous. Existing players who want to pick up these codes can do so from our list of free casino promo codes for existing customers.

Don’t forget to follow the steps above for the best gaming experience, and take the necessary precautions to avoid bonus abuse.

What are Free Daily Spins Promo Codes?

A free daily spins promo code is a promotion for existing players where you get a set number of free spins each day just for logging in, with or without depositing.

Casino Birthday Bonus Code

Most online casinos offer you a casino birthday bonus code: you’ll usually get it in the inbox of your casino account. It can be free spins, an up to 400% deposit match bonus or a tailored high-roller bonus for that special day.

Key Bonus Code Terms You Should Be Aware of

If you’re going to play with casino promo codes, read up on your slots and casino promo code terms as much as possible! Wagering requirements, minimum deposits, and the payment methods available are very important to know before depositing.

These are the main points to keep in mind for a safe and pleasant experience:

Key Bonus Code Terms You Should Be Aware of

Promo code accuracy

Pay attention to all letters and numbers as you enter them in the same order. Otherwise, the code may be deemed invalid and the bonus cancelled.

Eligibility

Slot promo codes may be granted to existing players or first-time depositors. Look carefully at who the bonus code is for so as not to create any confusion.

Most casinos require a verified account to go through and redeem a bonus code and complete the KYC process, so make sure you complete both tasks before depositing.

Limited activation timeframe

For most bonuses, there is a specific period in which you may redeem your casino promo code – from 7 to 60 days or more, depending on the bonus you pick. On the other hand, some may not require a set time or period.

Timeframes and additional information about all offers can be found in the full T&Cs.

Wagering conditions

  • Some wagering requirements can vary from 5x to higher amounts of 65x or 99x
  • If a bonus consists of spins + bonus funds, these may have different wagering requirements
  • Most promo codes are given on particular games
  • Pay attention to betting limits since some casinos have a £100 betting limit while others are lower, such as £12
  • Some payment methods, such as Skrill or Neteller, may be unavailable
  • Depending on the bonus amount, cashouts may be capped

How to Claim Your UK Casino Bonus Code Correctly

  1. Pick a bonus code from our list and follow the link
  2. Create an account and go through all the necessary steps
  3. On no-deposit bonuses, the promotion will be claimed automatically
  4. Check all the payment methods available for that particular bonus
  5. Make your first deposit and add the bonus code
  6. Your bonus will take effect after depositing is complete.

Ensure Your Deposit Qualifies! Use Eligible Payment Methods

Some slots and casino promo code bonuses condition you to use a specific eligible payment method. That’s why choosing the right payment method is extremely important. Here are some of the best options our expert, Ionut Marin, picked for our UK players:

Payment method Min-Max deposit Min-Max cashout Cashout speed Our verdict for casino bonus codes
Visa £10 – £15000 £20 – £10000 2-4 Days Recommended
Mastercard £10 – £15000 £20 – £10000 2-4 Days Recommended
PayPal £10 – £10000 £20 – £10000 Instant Recommended
MuchBetter £10 – £10000 £20 – £10000 Instant Not recommended

Why we recommend PayPal casino promo codes?

If you need help picking the best payment method from the ones above, we would go with PayPal.

Throughout our time reviewing and testing various payment methods, PayPal casinos consistently offer top casino bonus codes, fast withdrawals, and reasonable minimum deposits and withdrawals.

Due to the extended withdrawal time, Visa and Mastercard are closely behind in our preferences. We do not recommend keeping your gambling bankroll in your MuchBetter account because this payment service might not be available for claiming bonuses.

Casino Bonus Code Not Working? Ask Support for Help

You have many tools to resolve this issue. Our experts will show you how to do it:

  1. If you’re an unregistered player and your bonus code isn’t working, contact the customer support team for new players. They will help you in no time if it’s a technical issue.
  2. If you’re already a member and your bonus code for the existing player offer isn’t working, email them or contact the live support team within working hours.
  3. Make sure you’re eligible for the activation of the bonus code.
  4. Always read the casino’s T&C.

How We Protect Player Security – 3 Factors We Look At

Securing all your data is crucial when claiming a bonus and playing on a website. Pay attention to the responsible gaming tools the casino offers, as well as to the useful links such as Gamcare, GamStop or Gamban, and the license. Moreover, check if the website you’re currently on is SSL Encrypted.

These features ensure a safe gaming environment and guarantee your payments and personal information will not suffer any leaks.

How We Protect Player Security - 3 Factors We Look At

All promo code slots bonuses come from UKGC-licensed casinos

The United Kingdom Gambling Commission is the best license a casino can have. Running directly under the Government of Britain, it confers legitimacy and controls over what goes on in an online casino. A casino with a UKGC license will always have fair terms for slots bonus codes.

All casinos under the UKGC license have strict laws and rules they must abide by, as well as fixed penalties in case something goes wrong. Moreover, they impose links that send players to gambling addiction helplines.

Responsible gambling approach

If you ever feel you’re losing control over your gaming experience, our recommended UK online casinos with bonus codes offer links to various tools, such as Gamban or GamStop, which you may reach out to for help.

On top of that, responsible gambling is moderated and validated by eCogra, an institution in charge of mediating conflicts or helping players in dire situations.

Keep away from Bonus abuse

You can easily forget what bonuses you did or didn’t redeem, so in this part, we’d like to give a few tips on how not to claim a bonus twice, which can be considered bonus abuse.

  1. Check and jot down all active bonuses you have
  2. Access the Promotions tab
  3. Pick a bonus you don’t have yet
  4. Go through the process and redeem the bonus

Are Bonus Code Casino Offers Better than Regular Ones?

Yes and no. When you claim an exclusive promo code casino bonus, chances are you’ll get better perks than with a regular bonus: higher match percentage & bonus value, lower wagering and more free spins no deposit.

This is true, especially if you found your bonus code on curated platforms like KingCasinoBonus, where experts negotiate the bonus deals for you. Our reviewers take 10-15 hours to test each bonus code with your enjoyment in mind.

However, not every promo code casino offer is exclusive, so these bonuses are not always better. Based on our internal tests, only 33% of slots and casino promo code offers can be considered better in terms of match deposit (up to 1000%), bonus value (up to 1000 pounds) and number of free spins (100+).

King’s Expert Tips: Make the Most of UK Casino Bonus Codes

At KingCasinoBonus.uk, our main principle is to make gambling a state of the art and not something that will give you unwanted results; our expert, Ionut Catalin Marin, managed to gather some tips and tricks to master the casino bonus codes like a pro:

  • Don’t activate the bonus code before you’ve read the bonus policy: to master handling a bonus like an experienced player, you must read and comprehend the terms attached. If you don’t do that, you’ll lose the bonus too fast, creating inconvenient situations.
  • Games Availability: ensure the offer activated via bonus code will suit your gameplay style; otherwise, you’ll find it difficult to overcome the challenges.
  • Look for No Deposit Bonus Codes first: If you’re new to the bonus codes’ usability, the best way to learn how to handle them is to look for those offers without financial commitment. You must be aware that sometimes, when you try to grab a deposit offer via a bonus code, things can take a wrong turn, like typing the wrong code and losing the opportunity.

Gamble Responsibly: 4 Safe Practices for Using Promo Codes

Even if you find various bonus codes on our website, if you consider yourself in a bad-behaviour gambling loophole, you should consider a break from online/brick-and-mortar casinos for a while. No need for drastic actions; just take a pause to regain your pro player skills, and after that, come to our website and get your best bonus codes.

  • Take a break from gambling from time to time.
  • Even if the bonus codes are exclusive, you must know about the bonus abuse phenomenon. Sometimes, bonus code users unconsciously become bonus hunters, leading to lousy gambling behaviour – from this point, you can lose your casino account or, even worse, lose your funds very fast, which is the first step into irresponsible gambling.
  • Become a pro by gambling with patience and with healthy bankroll management.
  • Learn about mathematical strategies like Martingale, Fibonacci, Paroli, or D’Alembert to see how a gambling master plays. If you understand those tactics, you’ll see that patience, skill and math are required for responsible gaming.
