What is a Welcome Bonus?

The most alluring feature of today’s online casinos is the casino welcome bonus. You can find it in almost any form from free spins and bonus matches to no deposit bonuses and free bets.

Also called the ‘casino sign up bonus’, this casino welcome bonus is in fact a ‘gift’ from the site to you because you’ve decided to register at their site. 

Almost any licensed and fully-operating website will offer you these promotions trying to attract your attention and gain your loyalty. That’s why casinos compete with each other who’ll provide the best online casino welcome bonus.

Nevertheless, you’ll easily spot the casino with the best welcome bonus depending on the percentage of the bonus matches, the number of free spins, or the most thrilling incentive - the no deposit bonuses! 

However, no gift comes undeserved, so you’ll have to fulfill certain requirements to claim the best online casino welcome bonus. To unlock your welcome package or withdraw your bonus winnings, you’ll have to deposit a certain amount and fulfill the wagering requirements.

The casino sign up bonus is usually offered as a first deposit bonus, which means that you’ll have to deposit a minimum amount to start your reels rolling.

Why is Sign Up Bonus a Good Thing?

It doesn't matter if you’re a new or an experienced player - the online casino welcome bonus is how the website will introduce itself to you. 

Through these promotions, you'll get familiar with the different categories of games, software providers, winning chances, casino policies, etc.

The best casino sign up deals are a way to allure you and keep you into the game arena by providing you with chances to double, triple, or even quadruple your initial deposits. 

Boosting your bankroll is much easier with a welcome bonus - the site provides you with extra spins or free money which will expand your chances to settle on a winning streak.

Types of Welcome Bonuses

Each online casino has its welcome offer which can include one or several types of bonuses. The most frequent sign up bonus is the first deposit bonus - free chips or free spins matching your initial minimum deposit.

First Deposit Bonuses and Matches

When we talk about the first deposit welcome offer, we usually think of a match deposit bonus of 100%, 200%, and at some casinos even 300%. Nevertheless, the 100% bonus match is the most frequent one, and it provides you with extra gambling credits equal to the amount you’ve deposited.

Free Spins Bonuses

A sign up bonus can also be associated with a free spins feature which you can unlock after successfully depositing the required amount. Many online casinos, along with the bonus matches, provide their new players with a number of free spins, albeit often restricted to particular games or software providers.

The Welcoming Packages

The most thrilling and irresistible are the custom-tailored welcome packages that the online casinos offer. These welcome packages often consist of a match deposit bonus attached for the first, second, and third deposit. 

Each welcome bonus in this package may enable you extra spins or other incentives to boost your winning chances. These packages can sometimes go up to even 5 deposit bonuses, but the credits you get gradually decrease with every next deposit.

No Deposit Welcome Offers

You can sometimes stumble upon a welcome bonus called the ‘no deposit bonus’ which are very rare commodities but provide you with an opportunity to try your luck without depositing a penny.

The no deposit bonus is often found in the form of free spins and sometimes they are provided only for entertainment purposes, without a chance to withdraw your winnings. 

On the other side, as with any other promotion, the no deposit bonus imposes certain wagering requirements that you’ll have to fulfill before claiming your rewards.

Welcome Bonuses Associated With Payments

The sign up bonus can be also associated with the payment method you use. For example, some casinos will enable you extra features as a part of the welcome offer for using an e-wallet or virtual currencies. Nonetheless, this feature is something that you’ll hardly find on the internet.

Before depositing at any online casino, make sure to choose the bonus which suits your wallet and brings you the biggest and long-lasting rewards!

Finding the Most Suitable First Deposit Bonus

Each casino player is a world of its own, and that’s why many gambling sites try to differentiate when providing their customers with welcome bonuses. Casino players have their own preferences depending on their favorite games, providers, promotions, etc.

Today, the most popular type of welcome casino bonuses are the first deposit bonuses. Nevertheless, the industry is growing and the choice of online casinos is huge. Finding the most suitable first deposit bonus can be a complicated job.

Dazzling offers 

First of all, you’ll have to find the online casino which you think has the best bonus offer compared to similar sites. You can decide depending on how big the bonus match is, how many additional spins you’ll get, the minimum deposit requirements, game restrictions, etc.

However, we recommend that you don’t instantly jump at the online casino with the biggest reward, because there can be some hidden requirements that may disappoint you in the end.

The Wagering Requirements

Welcome casino bonuses often have different wagering requirements attached to them. The wagering requirements are something you must inspect before unlocking your bonus because they refer to the number of times you’ll have to play your bonus before withdrawing any winnings.

To put it simply, if the wagering requirement is 40x, you’ll have to play your bonus amount 40 times before withdrawing any winnings. That’s why we think that if an online casino offers a deposit bonus match of 500%, it doesn't necessarily mean that it’s the most profitable offer.

A first deposit bonus match of 500% unlocked with a min deposit of $10 and a 60x wager, is a great “trap” for inexperienced players. They’ll get 50$ to gamble 60 times before claiming their rewards. It’s clear as day - the probability of winning here is reduced to a minimum.

This is the reason why you should put on a scale the wagering and minimum deposit requirements on one side, and the percentage of the bonus match or number of free spins on the other side.

Terms and Conditions

The choice of online casinos is huge, but each one of them has Terms & Conditions where you can inform yourself in detail about the different restrictions and requirements. 

In our guide, you’ll find everything you’ll need to know about the games on which you can use your bonus, the wagering requirements, the expiration date of your bonus, minimum deposits, bonus codes, etc. 

Checking the Terms & Conditions is a must for both new and experienced players deciding on their most suitable first deposit bonuses. 

But don’t worry - we’ve separated the coolest first deposit casino bonuses which you can claim online!

Claiming a Casino Welcome Bonus

Once you’ve chosen your favorite online casino with the best welcome bonus, the next step is claiming it. It may sound easy, but many inexperienced players sprain their ankles when taking this step.

Minimum deposit

Every online gambling venue has its minimum deposit requirements before letting you claim the bonus. The minimum deposit varies between casinos and can be as low as 1$ and high as $20.

Check out these requirements and your wallet before deciding which is the best bonus for you.

Bonus codes

First of all, you’ll have to register your account and password at the site you’ve chosen. Then you’ll have to see how you can unlock the welcome bonus. This is usually done by using welcome bonus codes, and you should check if the code is automatically generated.

If the welcome bonus codes aren’t generated automatically, you will see the code displayed on a visible place of your screen or desktop. In this case, you’ll navigate to ‘cashier’, paste your code and deposit the minimum amount required. 

Another aspect you should consider is how many credits you will get by unlocking your welcome bonus. A casino with the best welcome bonus will often provide you with around 20 credits for your first deposit. Nonetheless, you should check out the value of each credit and how many spins or rounds you can play.

Restricted countries

Another issue when claiming your welcome bonus may pop out because of the URL you’re using. Many online casinos have a list of restricted countries where you can’t unlock these promotions.

That’s why we urge you to check thoroughly the Terms & Conditions of the particular online casino. For instance, some sites accept Canadian players and provide them with various types of welcome packages, while they refuse to offer their services to Australian players.

In this situation, if you are an Australian player residing in Australia, you’ll have to search for another online casino where you can claim your bonus.
