How Does the Bonus System Work in A Casino?


Online casinos are a very competitive field, which is why you’ll find that most of them offer similar promotions and bonuses. However, there are always slight differences between sites, so it’s important to know what each one offers in order to choose the best online casino to play at.

In this article we’ll go through some common terms related to casino bonus system offers and explain how they work so that you can make an informed decision about where your money goes when playing your favorite online game.

What Are Online Casino Bonuses?

The bonus offers at online casinos are one of their most attractive features. These promotions come in many different forms, but they all share the same goal: to make online casino players at feel welcome and give them a reason to keep gambling at that particular casino.

Some rewards are free money; others are free spins or free bets. Whatever they may be called, they’re designed to help you enjoy better odds while playing casino games.

Different Types of Online Casino Promotions

Good news! There are different types of online casino bonuses to attract online players. It is important to remember that each types of bonus, such as free spins bonuses or matched deposit promo is specific and has unique features. Check out some of the bonus system types we selected for you here:

New User vs Existing User Bonuses

New user promotions are typically more generous than existing user bonuses. New users will get a higher percentage of their deposit matched and some free spins or casino credits. Existing users usually only get a percentage of their deposit matched, even if they have been playing at the casino for a while.

Both of these types can come in various forms: Free spins, match deposits, gifts and event tickets (to name just a few).

Match-Up Bonus

A match-up offer is when a casino adds a percentage of your deposit amount to your account. For example, if you deposit $100 and they offer a 100% match-up bonus, they’ll add another $100 to your balance. This means that with only one deposit, your total balance will be doubled.

Of course, there are many different types of match-ups available. Each has its rules regarding how much money must be deposited before it can be used on wagers or what type of wager must be made before the bonus can be claimed as income.

No Deposit Bonus

No deposit bonus is a great way to try out a new casino without risking any of your own money. These incentives are pretty rare nowadays due to their simplicity, but if you’re lucky enough you can still find operators that offer them. It is pretty self-explanatory – you don’t need to deposit any funds to get the offer, you just need to sign up with the operator and claim the offer. 

Free Spins

Free spins are a lot like the other bonuses we’ve discussed so far. However, they have a few key differences that make them stand out. Free spins are free money you can use to play slots at an online casino.

The operators usually give you 10 (20, 30…) free spins for signing up and depositing, but they can be won through various other means after that as well. You don’t have to bet high amounts on each spin—you can just play small amounts and keep re-triggering your free spins until you run out of them!


A refer-a-friend is a type of bonus that you can get when you refer your friends to an online casino. The way it works is you will get casino credit on your friend’s first deposit, and they will also get a bonus on their first deposit. This is a typical incentive for new operators looking to grow their user base.

VIP and Loyalty Clubs

VIP and loyalty club rewards are given to players who have been loyal to a particular casino for a long time. They are a way for casinos to treat active players who have spent more time playing at their site than others. The bonus amount depends on how much you have spent so far and your VIP level in that specific casino. Here you can find exclusive promotions only available for high rollers!

What Are Online Casino Bonus Wagering Requirements?

Wagering requirements are a set of rules that casinos use to determine whether you can withdraw any winnings. The average casino requires you to wager your deposit at least once before you can make a withdrawal. Most operators apply this rule on a sliding scale depending on how much money was deposited into their account and how big the first deposit bonuses were.

What Is Game Contribution Percentage in Online Casino Bonuses?

The bonus system is a complex mechanism that depends on many factors. The game contribution percentage is one of them. Not all casino games from the chosen operator always count towards wagering requirements – poker, baccarat, blackjack, roulette and slots usually contribute differently to wagering requirements.

The percentages of each game’s contribution to your total wagering requirement will be stated in promotional terms and conditions, which means that you should always check it before getting any casino bonuses.


The bonus system at online casinos has been around for decades now so there are a number of different types available today depending on the site you choose. Some offer free spins on slots, others give out free cash for depositing specific amounts over time or completing certain actions like inviting friends or playing at least three times per week.

There are even some sites that have hybrid systems that combine all these options into one big package! So there you have it – all you have to do is choose the one that suits you best.
