4 common types of Online Casino bonus codes in the UK
There are several different types of casino bonus codes in the UK. Here are some examples of some of the ones you’ll most likely come across.
1. Matched Deposit Bonus Codes
A match deposit bonus code is typically used to unlock a match deposit bonus. A good example is the welcome 100 % match deposit bonus offered at All British Casino.
2. No Deposit Casino Bonus Codes
No deposit casino bonus codes are typically used to unlock bonuses that don’t require you to make a deposit to unlock them.
3. Free Spins Casino Bonus Codes

Free spin casino bonus codes are normally used for the purpose of activating free spins in different games. Sometimes the games vary significantly, however, games that are commonly associated with free spins are games like Starburst and Book of Dead.
4. Exclusive Casino Bonus Codes
Exclusive casino bonus codes are usually bonus codes that unlock bonuses that you will unlikely find elsewhere. An example is an exclusive bonus of 100 % up to £50 + 100 Spins casino bonus offered at Kaiser Slots.
Checklist to go through before you use your Bonus Code
Most of the information for all of the following can be found in the bonus terms and conditions. We highly recommend all players fully read and understand the bonus terms and conditions before opting into it.
✅ Winning limit
What is the winning limit of the bonus you plan to make use of? Always make sure you are aware of the winning limit a bonus has. This means that there’s a set limit for a win amount that you can withdraw.
✅ Time limit
Before making use of a bonus, be sure that you are aware of the time limit attached to it. In other words, make sure that you know when your bonus expires.
✅ Wagering requirements
It is extremely important for you to read up on whether your bonus has a wagering requirement and what this requirement is. You don’t want to find yourself jumping through a series of endless hoops just to withdraw your funds once that time comes.
✅ Allowed games
Some bonuses are limited in terms of the number of games they can be used on. Make sure that you are fully aware of what games you can use your bonus on and what games you can’t before you activate it.
✅ Game contribution
This is a very important point for us to cover. Some players may realise that the games they’ve decided to play don’t contribute 100 % towards wagering requirements a little too late. Make sure that the games you are playing with your bonus contribute 100 % towards the wagering requirement set for a particular bonus you plan to activate.
✅ Local restrictions
Make sure you are playing from the correct country (the UK) that a bonus requires before you activate your bonus. Likewise, it is imperative that you are using an online casino that is legally licenced and regulated within the UK by the UKGC.
4 tips to maximise your bonus code value
To make sure you get the absolute most out of your bonus code, we’ve got a few tips for you.
- Create a game plan according to your budget
Play responsibly by setting yourself a realistic budget for playing. This budget is typically referred to as a bankroll in the casino world. - Check the RTP of the games you want to play
It’s important to check that the RTP of a game you wish to play is in alignment with what’s considered fair. You would want to go for games with an RTP rate of 96 % or higher for the best possible chances of winning big. - Choose a bonus code according to your game style
Make sure to pick a bonus code that unlocks a bonus that allows you to play the games you most want to play. Don’t go for a table game bonus, if you typically gravitate towards slots, for example. - Enjoy your game!
It’s extremely important that you remember that playing should be fun and that you should stop playing if you at any point feel that it’s gone from fun to serious. Once again, check out our tips on responsible gambling if you’re ever in doubt!
Solutions for common issues
Issues are sometimes inevitable, and it’s natural that some people may experience issues when using bonus codes.
Below are some common issues people experience when trying to redeem their bonuses using a bonus code, and some solutions.
- I didn’t get the code
Some casino sites send bonus codes to the email address you entered when registering. If you have not received an email containing your bonus code, make sure to check that your email address has been entered correctly. It is possible that the bonus code can be found on your account.
- The code is not working
If the bonus code you’ve entered to unlock your bonus is not working, check to make sure that you have followed the necessary steps required and entered the bonus code correctly. If all else fails, we recommend that you contact customer support.
- I can’t withdraw the winnings
If you are unable to withdraw your winnings, ensure that you have met the wagering requirements, if any, attached to the bonus first. Also, ensure that your payment details are correct.
- The bonus disappeared
If the bonus has disappeared, it could be that it has expired, or you may not be eligible for that particular bonus offer. If you are sure that you are eligible for the bonus offer, contact customer support to receive further assistance.
- The casino didn’t pay out my winnings
Don’t fret if you don’t immediately receive your winnings after making a withdrawal request. Sometimes the processing time for funds can take a few days. If you’ve waited a minimum of 5 bank days without receiving anything, we would advise you to contact the casino site. If all else fails, do contact your bank to make sure your funds haven’t been withheld.
