Getting Acquainted With Bonuses
If the idea of an online casino bonus offer seems too good to be true, it's worth examining the logic behind them. There are more than a hundred licensed gambling sites vying for your business in the UK. In order to attract players and keep them happy, casinos dole out big bonuses. They can afford to do this because they aren't paying the high overhead of a physical casino.
Below are some bonus types you can take advantage of:
- Casinos will give you free cash on top of your initial deposits as a welcome
- This is usually done as a percentage of your deposits and might be spread out across your first few transactions
- To claim this bonus, you may need to accept it when making your first deposits or use a specific welcome code
No Deposit Bonuses
- Players can claim free cash without a deposit
- You'll usually only get a few pounds or free spins, but you can win real money
- Sites offering these usually don't require any codes for the bonus but you will need to register an account
- These are for existing players and reward you for making more deposits by percentage, matching your deposit amount or giving free spins
- Most sites offer these for depositing on certain days or for special promotions
- Claiming these bonuses might require a specific code or clicking on a link from an email or social media
- As the name implies, these are spins on real money slot games for free
- Some casinos dictate the game or developer for use with the promotions
- This online casino promotion is usually tied to your account and won't require any codes
- Some casinos offer a loyalty program to reward frequent players using points for every time you play or deposit. Points can be redeemed for cash or free play
- Extra benefits can include prize draws, luxury travel and even bespoke gifts
- Casinos will automatically enrol you in their loyalty program, so there's nothing extra you'll need to do to start earning rewards
Refer a Friend
- As the name implies, you'll get rewarded when you refer a friend to your preferred online casino
- Most sites will pay out a set bonus when your friend signs up and makes a first deposit
- To claim this bonus, your friend will need to use a specific link you give them, or your personalised referral code
Online casino bonuses make you a winner before your first hand or spin of the reels.

Frequently Asked Questions
How do deposit bonuses work?
When you claim a deposit bonus, you'll get extra cash on top of the money you add to your bankroll. For example, you might find a 100% deposit bonus that will double the amount of your initial deposit. Find out more in our guide to how bonuses work.
Can I cash out my bonus?
While bonuses are effectively free money, you can't withdraw your complimentary cash immediately. At an online casino, UK players must satisfy wagering requirements before cashing out. In other words, you'll need to play a set number of games first.
Do I have to be a new player to claim a bonus?
Although welcome bonuses are generally reserved for new players, the free cash doesn't have to end after your first deposit at an online casino. UK casino fans can take advantage of reload bonuses, promotions and loyalty rewards.
Can I claim bonuses on my smartphone or tablet?
It doesn't make a difference how you choose to access online casinos. UK sites give you a casino bonus on any iPad, iPhone, Windows Phone, Microsoft Surface, Android tablet or smartphone.
How do I find a great site with a big bonus?
Our gambling experts have tested and compared the best licensed gambling sites in the UK. If you're ready to claim free cash from a fantastic casino just visit any of the top-rated sites we've listed on this page.
What types of bonuses are there?
There are numerous types of online casino bonuses, like welcome bonuses that match your first deposits and loyalty programmes that reward you for playing and depositing funds. You can even get free spins or extra payouts when you refer a friend.
Are bonuses worth it?
Most of the time, bonuses add extra value for players although the terms and conditions can be confusing. That's why we explain them in our reviews and blacklist sites that don't live up to the online casino promotion.
How long does it take to claim a bonus?
Most bonuses will be claimed instantly, but computer systems and checks can mean that you'll need to wait 5-10 minutes for free spins or bonus money to appear on your account. If it takes longer than that, it's best to contact customer support.
What are bonus codes?
While some bonuses are allocated to your account automatically, others need to be claimed with a specific code. This will be given to you on a website, or via email or social media. Simply provide the code when making your deposit, and you will claim the bonus.
