Casino Bonuses

Online casinos use different methods to attract new players and keep existing ones, with casino bonuses being one of the most attractive ones. These online slot bonuses are the enticements that keep the players interested and casinos make sure that the latest and most appealing offers will be displayed when you arrive on their page.

Here at SlotsWise, we are constantly looking for the best casino bonuses from the most reliable online casinos. All you need to do is find a site that has the most suitable online slot bonuses for you and start your gaming adventure. You can even read our reviews on each of the online casinos that we recommend on our site. Casino bonuses change regularly, and we always ensure that the ones displayed here are up-to-date and accurate. So, on this page, you can check out the best casino bonuses UK for 2022.

Types of Casino Bonuses 

Online casinos are really creative when it comes to creating bonuses, and that’s why they come in different forms. The best casino bonuses UK have the same goal: to attract new players and keep those who have already started their journey. 

Even though you may come across a few types of online slot bonuses, choosing either one opens the door to the roster of online slots, table and card games. Let’s get into detail about the types of online casino bonuses. Let's take a look at what types of online slot bonuses can be found at some of the best casino bonus sites.

Welcome bonus

The welcome bonuses are also known as sign-up bonuses or first deposit bonuses. No matter the name, these types of casino bonuses have one goal: to attract and greet new players. Some of the most common types of welcome bonuses include free spins, free bingo tickets, match bonuses, spin the mega reel, scratch cards, and more. 

There are even casino bonus sites that give you the chance to claim a welcome offer without making a deposit. All you need to do to claim a no deposit bonus is to register at a casino that offers these types of online slot bonuses. At SlotsWise, we constantly search for reliable casino bonus sites that provide the best UK online casino bonuses.

Match Deposit Bonus or Reload Bonus

This type of bonus goes by a few different names and is really popular among players. So, when you go through different casino bonus sites, you might come across a match deposit bonus, matching bonus, deposit bonus or even reload bonus. In short, when an online casino offers a matching bonus, it means that it will match the deposited funds in the form of a bonus.

There are different matching bonus variations suitable for players that make small, medium and larger deposits. These casino bonuses can be split into three different categories: first deposit bonus, compound bonus and high roller bonus. Claiming the match deposit bonus is pretty simple and it can be done in different ways. You’ll be given a special promo code to enter after making a deposit, or the bonus might automatically be credited to your account.

Free Spins

Without a doubt, free spins are among the most popular type of casino bonuses. The free spins are credited to online slot games and allow you to play certain games for free, without risks. They are usually associated with a specific game that is stated in the terms and conditions of the offer. So, depending on the number of free spins you will be given, you can spin the reels on the previously chosen slot game. Oftentimes, these types of online slot bonuses come as a no deposit version, which is more favourable to players. It should be noted that most of the free spins bonuses usually have wagering requirements.

Refer a Friend Bonus

It’s one of the most common online slot bonuses and the concept is pretty much self-explanatory. You recommend the online casino site to a friend, and then once they join and make their first deposit, you get a bonus. It can be a fixed amount or tied to the amount that your friend deposited on their first deposit with the casino in question.

Loyalty Programme 

Most online casinos have loyalty programmes that offer different perks to the most loyal players. Every time you play at the same casino, you collect a certain amount of points. Keep in mind that different games come with a different number of loyalty points. Usually, slot games deliver more loyalty points, as opposed to table games for example.

Players are automatically qualified for the loyalty programme as soon as they use their welcome offer. The more you play, the more points you collect, which can be spent on free spins, bonus funds or other great perks. Loyalty programmes can have other benefits, such as custom bonus offers, faster money withdrawals, special casino tournaments, and personalised support.

Wagering Requirements 

One of the most frequent terms we all come across is wagering requirements, so let's explain what it means and why it is so important when it comes to online slot bonuses.

Wagering requirements are conditions that most casino bonus sites include. Each player must meet these requirements after they’ve claimed that bonus so they can withdraw their winnings. In short, a wagering requirement is the number of times that a certain player has to play the bonus funds before they can withdraw any winnings in cash. 

So, before you claim casino bonuses, make sure that you read the Terms and Conditions. All legit casino bonus sites will have the wagering requirements clearly stated there.

You might wonder what the purpose of wagering requirements is and why they exist. Well, actually, there’s a good reason behind this, and it’s not a way for online casinos to make more money. There are many anti-money laundering regulations, and wagering requirements are implemented so that the casinos can comply with those set rules. 

Promo offers

In addition to standard welcome bonus offers, you can also claim a range of other casino bonuses. These offers can be recurring, but they can also be tied to a specific date or event.

Casino Bonuses Conditions

We already mentioned the importance of reading the Terms and Conditions before choosing your best UK online casino bonuses. However, this part holds a lot more crucial information about the online slot bonuses that you need to be aware of before claiming them. This information includes:

  • What is the minimum deposit for the bonus;
  • Does the bonus have wagering requirements;
  • Is there a time restriction on using the bonus;
  • What games are included in the bonus;
  • Is there a promo code to enter?

Checking these things will help you get the most out of the casino bonuses and take advantage of them as much as possible. Here at SlotsWise, we feature only trustworthy casino bonus sites that clearly display all of this information about their best UK casino offers.

Mobile Casino Bonuses

We live in a time when a lot of players prefer playing casino games on their mobile devices. So, the logical question is – can I claim online slot bonuses on my smartphone? The answer is yes. Online casinos are aware that most of their players these days would rather be playing on their mobile devices, so the choice of device poses no difficulties when it comes to claiming your bonus.

In fact, some casino bonus sites offer special mobile bonuses, available only to players who either register from their mobile device or log in on their mobile device for the first time. Either way, playing your favourite online slots on your smartphone will not stand in the way of you getting your casino bonuses; it can actually improve your chances.

How Do We Review The Best UK Online Casinos 

Online slot bonuses, especially welcome offers, are just one aspect of online casinos. Despite being the most important aspect for many players, there are numerous other things that must be taken into consideration as well, when reviewing online casinos. The process can be summed up as follows.

Our team of experts signs up at casino bonus sites and tests every aspect of them - the speed, games, accuracy, and security level. They claim and test the casino bonuses to see if they work properly. All in all, for an online casino to receive SlotsWise's seal of approval, it must go through our in-depth process of reviewing. 

Online Casino Games

The game portfolio is another important criterion that we consider when we rate the best UK online casino bonuses. The top-rated casinos offer a diverse selection of games that includes various online slots, table games, live casino games, and more. It’s also important that these games are optimised to work well on desktop and mobile devices. 

Some of the casino games that the best online casinos UK offer include slots, blackjack, roulette, live casino, and more!

Payments
Payments

Of course, players want a variety of payment options to make deposits and withdrawals. For that reason, we always test the payment methods available at online casinos, from debit cards to e-wallets like Skrill and Neteller, online payments such as PayPal, prepaid cards such as Paysafecard, and alternatives like Pay by Phone. The trusted UK online casinos offer such payment methods and have written what protocols they use for protecting your funds on their site. It’s also important to check the processing times of the deposits and withdrawals, as well as the accepted limits.

Security
Security

Playing games at online casinos involves real money. For that reason, the safety and security of an online casino, especially the new online casinos, is the most important feature you should consider when looking for a place to play. When you find an online casino where you want to join, the first thing you have to do is to check if it’s licenced by the official gambling authority of the country you're living in. Then, make sure to check if the casino is up to date on the latest security technologies and protocols and whether it’s certified to provide fair play and honest payouts. You can check these details at the bottom of the casino’s homepage.

Licencing
Licencing

As mentioned above, a reliable online casino must be licenced and regulated by the country's proper authority where it operates. In terms of the UK online casinos, always choose to play at a casino that is licenced by the UK Gambling Commission. No site makes it into our top-rated UK casinos list if it doesn’t have a proper operating licence by this regulator. In addition, other regulators ensure that online casinos provide a secure gaming environment for players outside the UK, including the Gibraltar Regulatory Authority, Malta Gaming Authority, Isle of Man Gambling Commission, and more.

Mobile Experience
Mobile Experience

These days, more than 70% of online casino players in the UK prefer to use their mobile devices to play. This means that online casinos have to be mobile optimised to meet players’ expectations. Fortunately, almost all of the best casino sites in the UK have optimised their websites for mobile use, meaning you can play your favourite games from your mobile browser. In addition, some online casinos provide some of the best slot apps for Android and iOS devices. The UK online casinos that we recommend are easy to navigate on mobile, and you can easily access all games, promotions, banking options, welcome bonuses and other features.

Software Providers
Software Providers

An online casino won’t be able to operate if it weren’t for the software providers. Software providers specialise in developing high-quality and innovative games and create their own niche. The best UK casino sites have integrated a variety of games from many top-notch software providers, including NetEnt, Microgaming, Playtech, Evolution Gaming, Quickspin, Play N Go, IGT, Nektan, Eyecon, Scientific Games, Big Time Gaming, Red Tiger Gaming, Gamesys, and more. Go through the full list of the most popular and trustworthy software providers available at the best new online casinos in the UK.

The most popular methods of contacting customer support at the best UK online casinos are email, phone and live chat. In addition, all of the online casinos that we recommend on this page have FAQ sections that consist of questions that provide answers to some of the most common concerns, including issues of payments, access to your account, current bonuses and promotions, and also the games the casino offers.
