Online Slots Bonuses

Almost every online casino will offer a welcome bonus when you register, and many keep dishing out the bonuses as you play. In fact, there’s so many bonus offers available out there that if you wanted to, you could quite literally never play without a bonus.

For slot players this gets even sweeter too, as the humble slot bonus tends to have the highest match percentage and the lowest wagering requirements of all the games at the casino. You can read more on wagering requirements and other terms later in the page, but first let’s get straight to the good stuff as we’ve compiled a list of the best bonuses for playing slots.

Note: Seeing as we’re dedicated solely to slots on this site the terms and WR listed below are specifically for slots. They may vary for other games such as blackjack or roulette.

What Do I Need to Know About Bonuses?

One of the most common forms of promotions that you will find when registering with a new casino is that of a casino bonus. The bonus usually comes as some form of match on your opening deposit and then you will be required to work through the bonus amount in order to clear it.

The bonuses are the most valuable promotion you can get. They can start as low as say £10 and work their way up to over £1,000. But what you need to know straight from the off is that not always is the biggest bonus the best one to take.

You see each bonus comes with its own set of terms and conditions that people need to take note of. We’ve spoken previously about how free spins work and the things you need to look out for. Well, casino bonuses are no different and in fact, can be more intricate.

The key to getting the most from your bonus is knowing exactly how it works and what’s needed from you to clear the bonus. You need to work out exactly what you need to do in order for the bonus to be cleared and then decide if you’re going to be able to clear it.

For example, a bonus might state that you get a £500 bonus when you deposit just £100. Sounds amazing right, 5x times your money straight away! But the reality is that due to terms such as wagering requirements (more on this later) and the stakes that you are going to be playing, there is no way that you can clear this amount. In this case it could be that a £50 bonus would be better as even though the money is considerably less, you’re still able to clear the amount.

There’s plenty of things to discuss and plenty of things to take note of with each casino bonus. So, let’s jump straight in!

Bonus match

The first thing that you will be able to note is the bonus match. This is essentially how much bonus you are going to get based on the amount of money that you decide to deposit.

The match percentage can vary dramatically. We’ve seen some as low as 20% whilst others have been up to 1000% or even higher for some high roller offers that have had a limited running time.

You’d be right in thinking that you’re looking to get as big a match as possible. But you need to make sure that all the other points regarding your bonus fall into line as well.

There can also be a large number of bonuses that will do some sort of reload bonus as well. The reload bonus is where you get an additional bonus after claiming the initial promotion.

The amount that you can claim for these will vary once again and whilst it’s often pretty easy to get several reload bonuses, they are likely going to be less than the initial bonus. Most casinos will offer you these in order to keep playing, so if you are a regular player, then make sure you keep an eye out for potential offers.

Wagering requirements

The wager requirements are probably going to be the most important section for any casino bonus. It can literally make or break any potential returns that you might get from your bonus.

What they are, are terms that the casino sets out that you must meet in order of how much of your bonus you need to wager through. So, whilst they might offer you a bonus of say, £100 when you deposit £100, they may also require you to wager a certain amount of that bonus in order to withdraw it.

These wagering requirements are set up to stop people from simply just signing up to casino, claiming they casino bonus and then withdrawing the money.

The degree in difficulty of each bonus in terms of how much you need to wager will vary. What we will say is that regardless of the amount, you will always be best hunting out bonuses that have the lowest wagering requirements. Let’s run through a quick example of how this might work.

Let’s say that the casino you are about to sign up to is offering a 100% match on your first deposit of £100 or more. The casino sets a wagering requirement of 30x the bonus amount. So, if we deposit £100 and got £100 in casino bonus, we would need to place 30x the bonus amount to clear the money and be able to withdraw it. In this case 30 x £100 bonus would equal £3,000.

This may seem high, but this is a very typical offer that you will get from a lot of casinos. As you can see, you are going to need to really work hard to get your money.

Within this example you will see that we have mentioned that you have to wager 30x the bonus amount. But many casinos actually include both your deposit and the bonus amount, which makes a huge difference. If our deposit was £100 and our bonus £100, combined that would be £200. If we had to wager through 30x of both deposit and bonus (£200), then the total spend would need to be £6,000.

This is why we mentioned earlier in the article that it’s not always best to just go with the biggest bonus on offer as these often come with the biggest wager requirements. You need to make sure that you are going to be able to wager through the amount needed to clear your bonus, otherwise you might actually be better off not claiming the bonus at all, which you can do by opting out, or you can find another promotion that better suits your bankroll and budget.

Cashable v non-cashable

There are usually two types of bonuses that you can claim; cashable and non-cashable.

A cashable bonus is one that where you are allowed to withdraw the bonus amount after you have been able to satisfy the wagering requirements. So, if you deposit £100, got a £100 bonus and hit your wagering requirements, you would be able to withdraw both your deposit, your bonus and any winnings from that bonus.

A non-cashable bonus, sometimes referred to as a stick bonus is where you are able to use the bonus money to bet, but you can’t withdraw the money, even after satisfying the wagering requirements. For example, you deposit £100, get £100 bonus, but when it comes to withdraw, you can only withdraw your original stake and any winnings you’ve racked up at the casino.

Obviously from these it’s best to hunt out the cashable bonus as it means that you are getting more from the casino in terms of actual cash, rather than what would technically just be a free-play pass with their money.

The reason that some casinos offer non-cashable bonuses is to limit their losses. It’s also something that is not all well-advertised, so if you didn’t look out for it, the  it’s likely something that wouldn’t be on the radar for most players and they would miss out as a result.

Other key rules that you need to be aware of

The terms and conditions for some casino bonuses can be quite vast. But all generally have a core of terms that are pretty much industry-wide. The more you are familiar with, the better your chances of getting the right bonus for you.

Max/min bet

The most popular is the maximum and minimum you can bet with your bonus. As we’ve spoken already, all bonuses come with some sort of wagering requirements, such as a certain amount that you need to wager in order to clear your bonus.

In order to stop people just placing a single bet that covers the wagering amount, casinos often limit the amount that you can bet. Well, they actually wont limit the amount you can bet, but they instead limit the amount a bet can contribute.

For example, you need to place £2,000 worth of wagers with the casino to clear you bonus. The casino has a maximum bet contribution of £10. This means that you would then need to place at least 200 bets at £10 each. You can of course bet more than this, but only £10 of the amount will be counted towards clearing your bonus.

Game exclusions

The number of games that are going to contribute towards clearing your bonus will be limited as well. They are usually limited in terms of type. So, they a bonus might be limited to just slots, with table games, live casino games, side games etc. excluded from clearing your bonus.

The reason they do this is that the house edge is drastically reduced on some games over others. For example, you could go and sit and bet on red/black on a roulette table to clear through your bonus pretty quickly. This would be good for the punter, but the idea of having all these bonus terms to continue to encourage the person to keep playing at the casino.


You will also only have a set amount of time to clear your bonus. This will range from each casino and could be anywhere from 7 days up to 60 days, although usually somewhere in the middle of that.

If you fail to clear the full bonus in that time then your bonus will be moved. The casino may state that any winnings from the bonus money will be removed from your account as well.

Limited winnings

A lot of casinos will limit the amount you can win with your bonus. Again, this number will range and it’s one of the few downsides to claiming these sorts of promotions.

For example, it could happen that you win a jackpot on one of the slots worth tens of thousands of pounds. But, if you’re playing with bonus money then it’s likely the casino will have a cap on the amount you can win, severely reducing this price and potentially voiding it altogether.

If you are a player that likes to bonus hunt and chase for the big prizes, then using bonus money or opting into a bonus might not be the best route for you.

Knowledge is power

The fact that you’ve got this far in the article shows that you are looking to learn more about how casino bonus work. This is a really good thing.

The more you can learn about the intricacies of casino bonuses, the better equipped you will be in choosing the right bonus for you. As a casino player, you’re in an incredibly strong position in terms of being able to shop around the best offers. There are a plethora of casino bonuses available and each will suit some better than others.

The more you know about the bonus and what to look for, the more money you’re going to make.

High rollers command better bonuses

There’s little arguing that the casino loves a high roller. Just as much as people love the thrill of the chase with a jackpot, the casino loves the ability to take vast sums of money from wealthy people.

If you are a high roller and then our advice would be to contact a potential casino first before signing up to them. If you can prove that you are going to be playing for high stakes and over a long period of time, most of the larger online casinos will offer you a welcome package that far exceeds the promotions that are available for most players.
