Types of Bonuses 

Online casinos are really creative when it comes to creating bonuses and that’s why they come in different shapes and sizes. All types of bonuses have the same goal and that is to attract new players and keep those that have already started their journey. 


Even though you may come across a few types of online casino 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 casino bonuses.

Match Deposit Bonus or Reload Bonus

This type of bonus goes by a few different names and is really popular among the players. So, when you go through different online casinos, you might come across a match deposit bonus, matching bonus, deposit bonus or even reload bonus. 


The name pretty much explains this type of bonus. In short, when an online casino offers a matching bonus, it means that they will match the money that you deposit in the form of a bonus. There are different variations of the matching bonus, suitable for players that make small, medium and larger deposits. This bonus can be split into three different categories: first deposit bonus, compound bonuses and high roller bonus. Claiming the match deposit bonus is pretty simple and you can do it by following one of these three methods. 


  • You’ll be given a special promo code or bonus code, which you’ll need to enter after you make a deposit.

  • The bonus might automatically be credited to your account after you make a deposit.

  • You might receive the bonus via email. 


Online casinos offer different percentages of match bonuses, which most often range from 20% and all the way up to 500%. And here are a few examples of how the matching bonus works. If an online casino offers a 50% matching bonus up to £200, you will receive a bonus, depending on the deposit that you will make:


  • £20 deposit + £10 bonus = £30 in your account

  • £50 deposit + £25 bonus = £75 in your account

  • £100 deposit + £50 bonus = £150 in your account

  • £200 deposit + £100 bonus = £300 in your account

  • £500 deposit + £200 bonus = £700 in your account

Free Spins 

Without a doubt, the free spins are the most popular form of a bonus in the online gambling world. The free spins are solely credited to online slot games and they usually come on a specific slot. So, depending on the number of free spins you will be given, you can spin the reels on the previously chosen slot game. For example, if you are given 20 free spins on Double Bubble, you can spin the reels on that game for 20 times without paying. If you manage to land a winning, the sum will be added to your bankroll. 


Often, online casinos combine the free spins with a match bonus. Pretty amazing, right?


Keep in mind that most of the free spins bonuses usually have wagering requirements. But, you can read more about that below. So, stay tuned. 

Loyalty Programme

Nowadays, most online casinos have a loyalty programme that offers many different perks and benefits to their, yes you’ve guessed it, most loyal players. You might wonder how does the loyalty programme work. So, every time you play at the same online casino you collect a certain amount of points. Keep in mind that different games come with a different number of loyalty points. Usually, wagering on a slot game comes with a larger amount of points, than wagering on a table game, such as poker. 


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. Depending on the casino, you can exchange the points for free spins, bonus cash or even something else. 


There are other perks that come with being a part of a loyalty programme, which include custom bonus offers, faster money withdrawals, special casino tournaments, tailor-made rewards and even personalized customer support. 


Being loyal at a certain online casino pays off, doesn’t it?

Welcome Bonuses

Claiming an online casino bonus is a great way to start a gaming adventure at a certain casino and to boost the first deposit. Actually, the welcome bonus is how an online casino greets their new players. Online casinos compete between themselves by trying to come up with the best and most creative welcome bonuses to attract new players. This is all in favour of the players. Currently, we don’t believe that there’s any casino that doesn’t offer a welcome bonus to their new players. At SlotsWise, we are constantly searching for reliable and trustworthy online casinos that provide all kinds of welcome bonuses. Take a look at each one of them, find one that you like and then start your journey by claiming that welcome bonus. 


There are even online casinos that give you the chance to claim a welcome offer without having to make a deposit. No deposit bonuses are becoming more and more popular in the gambling world. All you need to do, to claim a no deposit bonus, is to register at an online casino that offers this type of bonus. 


The welcome bonuses are also known as sign-up bonuses or first deposit bonuses. No matter the name, this type of bonus has one goal and that is to attract new players to their casino. The welcome bonuses can be divided into different categories and one of them puts them into two types: cashable and non-cashable welcome bonuses. 

Cashable & Non-Cashable Welcome Bonus

So, before you choose an online casino, it’s best to take a look and see in which category does the welcome bonus belongs. Let’s start by explaining the non-cashable bonus first, which is also known as a sticky bonus. By claiming this type of bonus, it means that you can spend it by playing different online games available at that casino, but you won’t be able to actually cash out the money that you might win. The cashable welcome bonuses are the opposite of the previous ones. Playing with this type of bonus means that you can actually withdraw all of the money that you will potentially win. 

Wagering Requirements 

No matter if you are new to the online casino industry or you’ve already played your fair share of casino games, you’ve probably heard about wagering requirements. If you have something that’s unclear or some questions about the concept of a wagering requirement, you are in the right place. We will try to give you a detailed explanation of the meaning and use. Also, as you’ve probably seen so far, we’ve added a wagering requirements calculator on this page, which many of our users have found really helpful. Feel free to try it for yourself and let us know what you think!


Most of the casino bonuses come with some conditions that each player must meet after they’ve claimed that bonus. So, if the players don’t meet that condition, they won’t be allowed to withdraw the money. That condition that comes with claiming and using an online casino bonus is called wagering requirements. In short, a wagering requirement is the number of times that a certain player has to play the bonus money before he/she can withdraw any winnings in cash. 


So, before you choose an online casino because of a certain casino bonus, make sure that you check out the wagering requirements. Each online casino must clearly show this info and you can most likely find it in the terms and conditions. There are even casinos that offer low or even no wagering requirements. 


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


Q: Is it safe to claim an online casino bonus?

A:Before we recommend an online casino to our readers, we carefully review and test them. Not only that, these real money online casinos have all of their online slots and casino games tested by independent auditors and are licensed by the United Kingdom Gambling Commission. So, you can rest assured that you play in a safe and secure environment.


Q: What are casino bonus codes?

A:Bonus codes, or promo codes, are a combination of characters which can give you access to a specific online casino bonus. Usually, you’ll need to enter the bonus code after you’ve made a deposit at an online casino. 


Q: What are wager-free casino bonus offers?

A:The name pretty much explains it. The wager-free casino bonus offers don’t require the players to play the bonus money for a certain number of times before they withdraw the winnings in cash.
