Trying out slots is probably the first thing people think of when visiting a new online casino and at Slots Expert we can obviously see why. Slots offer a fun way to gamble online and the new generation of ultramodern slots manage to give us all the excitement we’re hoping for. The good thing about slots is that they’re available all over the Internet and it’s up to players to pick the online casino with the right slot bonus that fits their needs.

Operators are aware of that and that’s why they’ll need to come up with pretty strong arguments to convince online players to visit their casino. One way to do this is by coming up with all sorts of rewards making today’s online casino industry a highly competitive place. The downside about this is that’s it’s become rather difficult to pick a casino that offers both a proper slot bonus and a trustworthy platform. Luckily we’re here to help you out with our complete beginner’s guide. In this guide we’ll tell you more about the type of benefits you’ll find online, but also want to stress the importance of their terms and conditions. Read on to find out more about the best slot bonuses in the UK you could take advantage of.

How a slot bonus works

Even though there are many slot bonuses, they usually all work quite similarly. The common way of how online casinos set their offers to be used is by; either you deposit a certain amount and get extra money on top of your deposit to use on your favorite slot. Or in some cases, it is for a specific slot game. The best way to find out how the offer works, is by reading the guideline provided with each Slot bonus.

Most casino bonuses are slot bonuses

In fact, when online casinos talk about welcome packages or other promotions you’ll usually see that these are mostly — or even exclusively — meant for slots. Offering slot bonuses is a way for casinos to incentive their players to give it a shot, while visitors themselves can try out the operator’s game offer at rather favourable conditions.

The information on this page therefore mainly concerns slot related offers and is not meant for table games, live dealer games, or specialty games. Nonetheless, a lot of the information on this page might turn out useful for those interested in other types of casino games than slot machines.

How to get a slot bonus?

As most people, we also love free stuff and when it comes down to new online casinos, we truly enjoy using casino promotions (such as free spins, welcome bonuses and other recurring offers to test a casino’s game. To get a slot offer is quite simple. By looking through the promotion list from any of the top leading casinos, you will amaze yourself with the offers that they have in line. The best part? each offer has a clear ”how to claim” section to make it easy for you to pick and choose which of their offers you will try out. With our slot reviews you can get a broader idea of the website’s user-friendliness. Finding yourself an online offer is actually not that hard. Your best bet would be to check out the home page and the specific promotions page and, of course, to regularly check out our website. We update our page continuously.

Bonus/Promotions Page

Most casinos have got a dedicated promotions page that lists all available offers, therefore making it a very useful source to get a better picture of the casinos’ bonuses. This page generally not only includes the casinos’ current promotions, but also sums up the most important conditions. In addition to the promotions page we advise you to check the terms and conditions you can most likely find in the website’s footer.

Email Newsletter

Some offers are merely provided after registering at an online casino. Although not always required, we do advise you to sign up for the email newsletter so that you don’t miss out on any of the bonuses. Some players even get tailor-made offers sent to them by mail. This usually concerns either very loyal customers or players who haven’t played at a casino for a while.

Loyalty Program

Bonuses sent to you by email or directly into your online account can be part of the casinos loyalty program. Some operators offer you a special online code when it’s your birthday or if they want to thank you for your loyalty. We have to say that we’re quite a fan of these sort of bonuses as they are a token of appreciation, something we also highly appreciate.

VIP Program

Slot bonuses or even specific rounds are offered quite often by casinos to reach out to VIP players. This can include free spins for a certain slot or free coupons for a tournament. As for a loyalty program, these promotions are only available to a limited number of players.

Bonus Codes

Bonuses can be granted via free spins or top ups, but are not always credited automatically. Please note that in order to be entitled to claim one some casinos require players to fill in a special code which can be considered as an access code to redeem the bonus. Those with codes are mostly related to slot games and a very common for free spins, deposit bonuses, and no deposit bonuses. If you want to redeem the code you’ll need to be aware that the code is valid for a certain amount of time, basically the way most voucher code works. On the previously mentioned Promotions page you should be able to read where you’ll need to fill in the code and if they’re other terms and conditions.

What are the advantages of a slot bonus?

A lot of online operators have made it a style statement with slot bonuses and many of them come with a recurring way of offering players advantages on a continuous basis. Casinos entice their players by offering all sort of gifts and why should anyone pass on such a chance, as the advantages of a slots bonus speak for themselves? Just to name a few:

Bonus cash

The most important reason players make use of bonus offers, is because they want to get their hands on cash. Whether you are getting a 50% or 100% deposit bonus, the idea of getting your deposit topped up means that you get more time to play the games you love with the same amount of money. That gives you more space to win a big prize, although most casinos limit the maximum bets in order to avoid that players win and walk away with a big payout.

Trying out a new casino

Slot bonuses are often offered as a way for a casino to introduce itself to new players. By offering players bonuses, like deposit bonuses or free spins, players have the opportunity to check out the look & feel of a casino and to see whether they feel comfortable playing there.

Trying out a new slot

Both deposit bonuses and free spins offers give players the opportunity to try out slot games. This can be true for new slot launches, but their preferred online casino not offering a particular game title can also be an important reason to give it a try at a new casino.

Not to be confused with the demo mode

Trying out a new slot machine should, however, not be confused with something completely different: trying a slot for free by using the demo mode. In addition to their bonuses, many online casinos also offer the option to play slots in the demo version using virtual credits. In this case, virtual credits also means virtual profits, therefore not leading to actual winnings. With a no deposit bonus you play with real money, although we’re talking about money given to you by a online casino. And let’s face it: why should anyone reject such an opportunity?

How to wager a slot bonus

The idea of online casino offers is obviously to be giving and generous, but even in the UK some bonuses have quite some stipulations when trying to redeem them. Before accepting any, you’ll need to pay particular attention to the bonus terms and conditions. This especially holds for the so called wagering requirement. We all know online casinos aren’t very keen on handing out free money, but it’s simply because they want to make a profit out of it as soon as possible. Here’s how it works when talking about wagering:

Why do casinos work with wagering requirements?

Wagering requirements are meant to avoid that people register, cash out the bonuses, and disappear once and for good. As you will imagine, this kind of makes sense, because otherwise people would withdraw their credits straightaway without even spinning once. Therefore they come with the condition that you’ll need to play through the bonus a certain number of times. The actual number depends on the online casino, the slot you’re playing, and the type of promotion. Luckily, slot fans generally get the best deals, as most apply much stricter conditions for table games and live dealer games.


So what does a wagering (also called playthrough) requirement look like for slots? Let’s say, you accept a 100% match bonus up to a maximum of £100. You decide to deposit the full amount of £100. This offer has a 30x play through on both the deposit AND bonus. That means you will need to wager an amount of £200, 30 times. That sums up to £6000.

Always check the terms and conditions

In other words: please ensure you understand the bonus terms and conditions. If you’re not sure about the conditions, we urge you to contact the online casino you’re playing at. Also bear in mind that each casino will work with different terms. Some games work with maximum bets per round and others work with even stronger wagering requirements; at the end it all depends on the casino and the game you play.

What are the other slot bonus conditions?

Speaking of terms and conditions, the wagering requirements are just one of the many rules online casinos apply when offering slot bonus rounds to their players. After all, they don’t just appear out of the blue. You will have to take into account conditions such as:

  • One-time validity: usually bonuses can be redeemed only once. That is, once per online account or per IP address. As most casinos require their players to send a copy of their identity or bank account in order to process payouts you’ll probably won’t be able to work around this requirement by adding a new account.
  • Validity period: won’t remain valid indefinitely and most promotions work with a maximum period of validity. You will, therefore, have to claim the offer within the predefined term. Often this is set at either 24 hours, 7 days, 14 days or 1 month, depending on the type of bonus. Usually this counts from the moment of registration and there’s also a validity period for the wagering requirement itself.
  • Real money first: this condition is particularly important for existing customers. In case you already have got money in your account, but are entitled to a promotion, you’ll first need to play through your current credits in order to spend the bonus credit. In other words: real money will always be used first when you have both real money and bonus credits in your online account.
  • Maximum bonus money: the most common deposit offer you’ll encounter is the 100% deposit bonus, meaning you will receive the same amount that you deposit in real cash. That could be as little as £100, in which case you will get £100 cash when you deposit £100 in real money. Should you deposit £150 instead, you will still only receive £100 from the online casino.
  • Game types: most are meant for slots and therefore casino offers are often less favorable for table games, live casino games, and jackpot slots.
  • Game titles: not all game titles are eligible. Your slot bonus UK might only be valid for certain titles, certain game developers, or even specific titles from a specific developer. We therefore advise you to double check the list of valid games.
  • Withdrawal conditions: although not directly related, the withdrawal conditions can definitely affect possible winnings. Most operators set payout limits to avoid players can check out large winnings at once. Now imagine that you are lucky enough to win £30.000, but that the monthly maximum withdrawal is set at £7500.

Different type of slot bonuses

If you enjoy getting the more for less, you’ll most likely want to get the most out of certain casinos programs. We’re glad to say that slot offers do come in different ways. Most casinos offer a welcome bonus, which is meant to those who’ve just signed up, but there’s (a lot) more:

Deposit bonus

This is called this way, because players are required to first make a deposit into their account before they can claim it. There are different ways to do so (using either a credit card or an online wallet) and there’s normally also a minimum deposit players will need to make in order to be entitled. Deposit bonuses are quite often called ‘match bonuses’ because online casinos match the deposit amount or at least a reasonable percentage.

Free spins

Some players, especially the slot lovers amongst us, prefer slot bonus rounds to deposit bonuses as these free spins give them a direct opportunity to spin a new slot release. Like other offers, free spins can be provided as part of a welcome package, reload bonuses and even recurring promotions. Some online casinos tend to reward their players with free spins whenever a new casino game is launched.

For example

Casino X gives you 12 free spins on the game Starburst by NetEnt with a validity of 7 days and a minimum deposit of £20. This means you’ll have 7 days to deposit £20 and that the free spins are only valid for a specific game, in this case, Starburst. Free spins may also be a standalone offer, but are often combined with a deposit bonus.

Reload bonus

The reload bonus basically looks like a deposit bonus, but is actually meant for existing clients. Many online casinos send out these offers to win their old customers back and incentive them to make a deposit. Reload bonuses are pretty similar to deposit bonuses, but may match only 25%, 50% or 75% of a deposit instead of, for instance 50%, 100% or 200%.

No deposit bonus

No deposit bonuses are amongst our favourites as they don’t require any money to activate them. As a rule, this bonus is normally offered to new players, but sometimes loyal customers can also take advantage. In other words: you receive a tangible gift of the casino, which is obviously hard to refuse. This is a 100% cash offer that the online casino will put into your account if you decide to accept it.

New Slot Bonus

Although a new slot may be comprised of one of the type of slot bonuses mentioned above (such as a free spins or a cash back for a new slot game), we’ve listed the new slot as a separate type of promotion as it can be considered a bonus objective on itself.

  1. Free spins: one of the best ways for game developers and online casinos to promote a new slot game is to offer a specific promotion to customers that only apply to that particular slot. These sort of new slot bonuses most commonly include a certain amount of free spins both a casino and the game developer are willing to offer so that visitors can get the hang of the new game.
  2. No deposit bonus: a no deposit bonus might just be valid for a particular slot game. In this case players will indeed receive a certain amount added to their online casino balance, but with the condition that this money will need to be used for a specific game. Normally, players receive amounts of £10, which should be enough to give a decent number of spins to get to know a new game.

Daily/Weekly/Weekend Bonus

Slot promotions can also be offered in such a way that they’re only valid on a specific day. In order to boost traffic during the weekend it’s quite common to see casinos offering promotions on the Friday, while the same holds for the Monday so players keep on playing once the weekend is over. Special events, like St. Patrick’s Day, Christmas or New Year’s, are also very common moments for casinos to come up with an offer. For the best slot bonus in the UK, St. Patrick’s Day always seems a good moment to look out for attractive promotions.

For instance:

Casino X offers 12 free spins for a specific slot machine, but only on Fridays and strictly for players that are part of the VIP-Program. This means that not everyone is entitled to use the bonus, nor is every game. Other terms and conditions (such as a certain validity period and wagering requirement) can apply as well for daily, weekly, or weekend promotions.

Final thought

In our opinion slot promotions should be accessible for everyone and we hope you’ll be able to find yourself an offer that suits your personal interests or preferred slots. That, however, does not imply that we encourage you to participate and claim every bonus without knowing the conditions or knowing the operator. We therefore strongly advise you to only play at trustworthy online casinos that hold licences in either the UK or the European Union. At the end: at Slots Expert we try to make your online casino experience as pleasant as possible. And with our extensive list of casinos we might just manage to do so.
