Types of Casino Bonuses

All online casinos have a wide variety of bonuses on offer. Knowing what you’re getting into by accepting a bonus is the best way to increase your odds of coming out a winner. It is a good idea to read the terms and conditions before joining a site, and it’s never a good idea to join just for the welcome bonus. Here, we discuss some common bonuses you can expect at online casinos.

Welcome Bonus

These are specifically aimed at new players and can take any shape or form. Some sites offer a match bonus paired with free spins while others offer free games. Some merely offer a sum of cash to be added to your account.

No-deposit Bonus

While most bonuses require a deposit, the no-deposit bonus does not (big surprise). All you need to do is sign up and you can grab some credits or start playing free games.

Match Bonus

A match bonus is offered based on the amount you deposit into your account. Some casinos offer match bonuses up to 200%! This means that if you deposit £100, the casino will give you £200 for free! These bonuses are usually paired with strict wagering requirements.

Tiered Bonus

Tiered bonuses are for those who play frequently. The more you play, the higher your chances are of getting more rewards! Some casinos even offer referral bonuses. To make the most of these offers, it is best to keep an eye out for weekly or daily rewards that are up for grabs!

How do I get Started?

First things first. To grab a fantastic bonus, you need to have an online casino account. Let’s take a look at how you can reap big rewards and start playing for real money today.

Step 1: Select an Online Casino

Find a UK online casino you want to join. We’ve highlighted ten of our top choices for bonuses in our comparison table above. Join any one of these for a rewarding experience and plenty of bonuses.

Step 2: Create your Casino Account

Once you have found a suitable site, you need to create your account. Simply follow the prompts as requested by the casino and provide them with all your details. If you have decided to join a site that does not require a deposit before claiming a bonus, you can skip the next step below.

Step 3: Deposit Some Funds

If the site you are joining offers a match bonus or requires you to make a deposit, simply head to the cashier section and select a deposit option. Provide all the necessary details, e.g. account number if you are using debit or credit card or email address if you are using an e-wallet. Next, you must stipulate the amount you wish to deposit and wait a couple of seconds for your account to be credited with the cash.

Step 4: Start Playing and Winning

Now you are ready to claim your bonus! Whether you want to play slots or join a live-dealer game, you’ll have plenty of games to choose from to make the most of your online casino bonus.

Frequently Asked Questions

You probably have a bunch of questions rushing through your head! Being knowledgeable when it comes to online casino bonuses is your best bet for making the most of them! Here are some of the most common inquiries regarding online casino bonuses.

How regularly will I be able to benefit from bonuses?

Depending on the site you join, you will be able to get bonus offers on a fairly regular basis. Some sites offer daily, weekly and monthly bonuses. If you are looking to make the most of your bonuses, make sure to log in regularly.

How do I claim a casino bonus?

If you want to claim a welcome bonus, all you need to do is sign up. Additional bonuses are offered as you play or via other channels. Some sites send out email notifications while others have notifications displayed on their sites on a dedicated bonus page. To claim these promotions, you need to either click on a button or contact customer support to express your interest.

Can I reject a bonus if I am not interested?

It is important to note that you are in no way obligated to accept a bonus offered by any online casino. Players can reject bonuses if they do not feel the need for them. Be sure to read the casino’s terms and conditions as some bonuses will have their own sets of rules and requirements.

How do I know if a bonus is a good offer?

This all depends on your preference. If you are a slot enthusiast, a bonus providing free spins would be a good fit for you. If you like to play for high stakes on table games like baccarat, a match bonus is probably what you want to look for.


Now that you know all the best UK online casinos and their bonus offerings, you are probably eager to open your account and claim one for yourself.

We always remind players that online gambling should not revolve around bonuses and that other features should also be taken into consideration before joining any site. Be sure you will be able to make the most of the bonus offer and that you will be able to bank safely and effortlessly.
