How Top Casino Reports rates casino bonuses
Casino bonuses are simple to understand. They’re promotional rewards that casinos offer to new and returning players, so that they choose to wager on their games and not with another site.
But rating bonuses is more complicated than simply picking the highest ones.
This is because there’s more to bonuses than just the spins or cash on offer. That’s why when we rate casino bonuses for you, we also look at these top-level issues:
Wagering requirements
Deadline for use
Number of deposits required
Any games restrictions
Below, we go into more detail about how we look at these issues:
Wagering requirements
This is the amount of your own cash you need to invest to get the full benefits of a casino bonus. Some rewards are subject to 35x wagering requirements, others might have none.
However, more often than not these requirements do need to be met and it means that you might need to spend a significant amount of your own money to get your 100 free spins or £100 welcome bonus.
We highlight the wagering requirements of a casino bonus, so you know exactly what’s expected of you when you sign up to them.
Deadline for use
Many casino bonuses have a deadline for use, something you need to be aware of before you sign up to a £100 bonus, 100 free spins offer or any other type of reward.
We carry out a free spins valid check and cash bonus assessment by looking at how long you have before you have to use the reward.
This information is included in the terms and conditions of the bonuses we highlight in our reviews and you can find this in the table at the start of this guide.
Number of deposits required
Cash bonuses often advertise huge deposit boosts, with some casinos offering you the chance to boost your deposit by thousands of pounds.
However, these bonuses are often linked to a series of deposits of varying amounts which means you need to invest a large amount of your own cash to get the full amount of the reward.
Any bonus that requires multiple deposits must make this clear in the terms and conditions of the offer. Our reviews ensure that it’s simple for you to find this information and make an informed decision about whether it’s the right offer for you.
Any games restrictions
Casino bonuses in the UK can have a huge number of conditions attached to them and game restrictions are one of the most prominent.
Game restrictions relate to both the specific title you can use the bonus on and how the reward can be used. These are two of the restrictions to keep in mind:
Only cash stakes: this means that only cash stakes qualify, so you can’t use the bonus on free games.
Max bet using bonus: in this scenario you can only make bets of a certain amount on your favourite casino games using bonus funds.
We consider all these things when deciding which sites have the best casino bonuses. The key when choosing which casino bonuses to sign up for is to think about what matters most to you.
Once you’ve done this, make sure that you check the T&Cs of any bonus to make sure it really offers what you want and expect.

How do free spins work?
Free spins are the best casino bonuses for players who prefer slots games to table options.
Free spins work by giving you casino credit to use on slots games. What you need to keep in mind is that many of the offers can only be used on specific titles.
Wagering requirements is another key part of how free spins work.
This is because wagering requirements are the amount of money you need to invest at a casino before you can withdraw the benefits of the bonus.
You can find out all the information you need about how a specific free spins offer works by reading the T&Cs of the promotion.
How do welcome bonuses work?
Welcome bonuses are rewards casinos give to new gamblers when they create an account.
Welcome bonuses work by giving you either free spins or cash to use at a site, with the majority of these offers being a cash promotion.
Deposits are crucial to how welcome bonuses work.
The reason for this is that to get the full amount advertised you’ll often need to make multiple deposits, with many casinos giving you a different deposit percentage match for the different increments.
You can learn all you need to know about how a particular welcome offer works by reading the bonus terms and conditions of the reward you’re interested in.
How do no deposit bonus offers work?

No deposit bonuses are casino rewards you earn without needing to invest your own money.
No deposit bonuses work by providing either free spins or cash to use on casino games, with most casinos offering the former.
Deadlines are vital to how no deposit bonuses work.
It’s so important because many casinos will give you a set amount to claim your bonus. The reason for this is that sites aim to entice people with a free offer, then payout as few as possible by making them run out shorting after players have signed up.
Other types of online casino bonuses (high roller, 1st deposit, reload & more)
There are countless online casino bonuses advertised across the web, which makes understanding exactly what’s on offer a rather challenging ordeal. But don’t worry. In this section, we look to make things simple and clarify what you need to know.
Here are some other types of online casino bonuses and what they’re all about:
1st deposit bonus: a bonus offer (either cash or free spins) that’s linked to the first deposit you make to the site.
Match bonus: a match bonus is where a casino matches or exceeds your exact deposit amount, usually by 100%, 200% or 500% (which is the most you will find).
Cashback bonus: the casino pays back any losses you incur, making this offer essentially a refund to the player, but like with deposit bonuses the casino keeps the winnings.
Bonus code offer: accessible via code to trigger the offer.
No wagering bonus: a rare bonus applied to your account with no wagering requirements.
VIP bonus: this is an exclusive offer only available to certain players, which is typically tailored to your average deposit amount and playtime.
Loyalty bonus: rewards players who use the online casino for extended periods of time.
Referral bonus: comes on the back of a promotion from a friend or family member.
Reload bonus: triggered after the welcome package, this works like a standard bonus and can be based around a player’s number of deposits with the casino.
High-roller bonus: these bonuses are large, with the caveat being the clearing rates are much higher and are reserved for those playing high stakes.
Game provider bonus: based around specific game providers like NetEnt and Playtech.
Game specific bonus: tailored to games like blackjack, poker, roulette, slots, and bingo.
There are loads of bonuses on the market and not all of them are clear. Use this guide to help define the offers that best suit your needs and playstyle.
Dos and don’ts of casino signup bonus offers
There are some important things you should and shouldn’t do when you’re signing up for the best casino bonuses.
Do these things when signing up for casino bonuses
Read the terms and conditions
Decide if you prefer free spins or cash offers
Set gambling limits when using your bonuses
Don’t do these things when signing up for casino bonuses
Expect to get free money from gambling sites
Invest more money than you’re comfortable with just to get the bonus amount
Create multiple accounts with sites to try and get more offers
What are wagering requirements?
Wagering requirements are amounts of your own money that you need to wager before you can get the full rewards of a casino bonus.
They’re represented as a multiplication of the bonus amount on offer – such as 35x – and you can find them in the terms and conditions of the bonus.
Using the example of a £100 welcome bonus, this is how wagering requirements work:
10x: you need to wager £1,000 before you can withdraw the bonus
20x: you need to wager £2,000 before you can withdraw the bonus
30x: you need to wager £3,000 before you can withdraw the bonus
T&C’s of casino bonuses
It’s vital that you read the T&Cs of any casino bonuses that you sign up to.
Many sites advertise large cash of free spins offers and it’s easy to think that all you need to do is create an account and then you’ll get your reward.
The reality is different.
You’ll need to meet a number of different requirements, some of which may require you to invest your own money at the site to get part or all of the bonus.
Casinos are required by law to publish the full T&Cs of any reward they promote. You’ll normally find this in the small print of the bonus.
In addition to this, there are other requirements you can expect from casino bonuses:
Contributing a number of deposits
Making deposits in a specific period of time
Depositing a certain amount of cash
So, make sure you check the wagering requirement of a bonus before you sign up. If you don’t then you might find you need to invest a large amount of money just to get a small reward.
Most popular types of online casino bonuses
There are three main types of casino bonuses that you should look for at the best gambling websites:
Welcome bonuses
Free spins
No deposit bonuses
While there are other rewards you can sign up for, these are the most popular casino bonuses.
Online casino offers to avoid
There’s a trick to spotting online casino offers to avoid – look for the wagering requirement
These are offers to avoid because they require you to wager large amounts of your own money before you can get the full benefits of a bonus.
It means that if a bonus has a high wagering requirement then you might end up paying lots of your own cash to get its benefits.
Why you should look for the best loyalty reward casino bonuses
Great introductory offers are among the most important casino bonuses you can get. You’re rewarded with cash or free spins for depositing your own money, or simply for signing up to a casino.
But you shouldn’t only look for the bonuses that new gamblers get.
Why?
Because you can only get an introductory bonus once from a casino, and that might not be enough of a pull if you want to keep going back to a gambling site – this is where loyalty reward bonuses come in.
There are two key types of loyalty reward bonuses:
Casino membership
Ad hoc promotions
Many online casinos offer both these bonuses and different ones can excel for either their membership offer or their ad hoc promotions. We’ve picked out the best casino for each type of bonus.
How to claim an online casino bonus
While every casino and the bonuses they offer are different, typically, claiming a bonus follows a simple (often standardised) process.
Here is our general five-step guidance for claiming your online casino bonus:
Register your account: create an account with your chosen online casino
Locate and check the terms: find and understand the stipulations
Trigger the bonus: claim the bonus and check it is active on your account
Clear the bonus: make a plan to use your bonus and maximise its value
Track your progress: see what you’ve cleared and how much time you have
Every bonus is different and the process may deviate from this guidance, but there should be core similarities where you can recognise and apply these tips.

Is your preference for free spins or a cash reward?
