What Is a Casino Welcome Bonus?

So, what is the welcome bonus? You can simply understand it as the casino's welcome gift for their customers, both to show hospitality and to flaunt their exclusive incentives. For that reason, the welcome bonus is always brought out for comparison between different online casinos, and the casinos that lose in this contest will find it difficult to attract users. Understandable, right?

Since the welcome bonus is considered the most attractive offer of a gambling platform, it can be as huge as Vegas Casino Online with its $10,000 Match Bonus, or much smaller like SuperCat Casino with only a $1,000 Deposit Bonus. There are tons of options to choose from, enough to give you a headache all night!

The only similarity between them is that only a few types can appear, no matter how their values change. You won't be able to find exclusive deals out there unless you read it somewhere. Of course, we also include exclusive offers for you, but that's for another time. Our job now is to find out about the best welcome bonuses of 2021, right? Let's move on to the next part.

Types of Online Casino Welcome Bonuses

Welcome bonuses come in many different varieties, and each online casino offers one or more different types of welcome bonuses. However, we only classify them in only two types, depending on how they are activated, namely deposit bonus and no deposit bonus. All other different names fall into one of these two forms.

Deposit Bonus

A deposit bonus requires you to deposit before activating the offer, as the name suggests. A welcome package will usually come with several deposit bonuses, arranged in order of first deposit, second deposit, third deposit, etc. These incentives will match the amount you have cashed in and put them in your account. That’s why they are also called match deposit bonuses.

Each match deposit bonus comes with a limitation, which is the maximum amount that can be given. For example, if you come across a 100% up to $100 match deposit bonus, it means that the highest bonus you can get is $100, even though your deposit can be increased by 100%. Thus, don’t bank in more than the bonus limit, else your excess deposit will be wasted.

Another thing to remember: there can be free spins or free cash in between the deposit bonuses. They can be valuable to many players, especially if they are into slot games. Who doesn’t want 30 free spins in Starburst, right?

No Deposit Bonus

For the no deposit bonus, you won’t have to spend any actual money. In fact, the casino will give out a small amount of cash for you to play, providing that you fulfill their prerequisites. Unfortunately, no deposit bonuses often come in small amounts in exchange for the “free value” they provide. Still, they are one of the best welcome bonuses that a punter can get.

No deposit bonus also comes with limitations, even more than the deposit bonus. You need to fulfill the wagering requirements to cash out your winnings, which is often 30 times the deposit + bonus amount. Also, all the conditions must be cleared out in certain days, depending on the casino. If you fail to meet the requirements, your bonuses are gone for good.

Above are two types of welcome bonuses that you can encounter at any casino. Simple and straightforward, right? After learning about the kinds of bonuses, the next thing we need to do is figure out how to use them. Moving on to the next part!

How to Claim a Casino Welcome Bonus

Before you redeem a welcome bonus, there are a few things you need to do first. The first thing is to do thorough research. There are many different online casinos, and each platform offers a different welcome package. You need to find out if the casino is right for you and whether the welcome bonus is worth it or not. How?

A suitable casino must first allow players from where you live. For example, you cannot play at a site that bans UK residents if you live in London. Many places even prohibit the use of VPNs, so changing your IP address is entirely pointless. Instead, choose an online casino that is friendly to your country.

The next thing you need to do is check out their payment methods. Even if the casino allows you to play, you won't be able to earn a dime without proper deposit and withdrawal methods. Many casinos accept PayPal, MasterCard, or VISA, so we recommend using one of these three payment options. Otherwise, just play and pay by the methods you find most convenient.

Now that you have a casino with a suitable payment method, the next thing to do is register for an account. You will need to fill in some personal information, such as your address and phone number, along with your bank account (if applicable). You can update the information later, but don't forget you can't use the deposit bonus without any deposit.

Some welcome bonuses require a bonus code, so you need to check carefully before proceeding to register. Entering the promo code can be done later in the cashier section, so don't worry too much. What you need to pay attention to are their terms and conditions. As we explained above, the bonus amount will be nullified if you do not complete the eligibility within the allotted time. Chop chop!

There are many things that need to be done, and it can take quite a while to deal with them on your own. However, don't overthink because we will do our best to help you. With all the reviews and the latest welcome bonus database, all you need to do is choose the right offer - and do a little reading.
