The casino welcome bonus, also known as a sign-up bonus, is a way for a casino to greet you upon registration

Casino Welcome Offer

A casino welcome offer, or welcome bonus, can come in many forms. Regardless of what form it may take, it won't leave the new player empty-handed. Free spins can be used to play slots, and bonus cash is usually associated with table games. However, there is more than one type of welcome bonus available at casinos. This is why you might find the need to compare welcome bonuses in our list above before picking yours.

The best welcome bonus casino and the best casino sign up bonus are the ones you deem best for yourself. If you're a slots fan, then you'll be looking for free rounds. If you're a table games fan, then you'll be looking for free chips or bonus cash offers. Whatever you're looking for, you'll definitely find it on our lists.

Free Welcome Bonus No Deposit Required Casino

The online casino bonus without deposit is one of the most popular welcome bonus offers offered by so-called free welcome bonus no deposit required casino sites. It's second only to the casino welcome bonus no deposit no wagering requirements offer. According to some, it's also the best welcome bonus because players don't risk their own money. When players acquire such a bonus, they get an additional amount of cash, free chips or spins to play with.

However, there are wagering requirements that the player must fulfill before withdrawing the offer. These usually boil down to wagering a certain amount of cash or free spins on certain games. By doing so, the player makes sure to have the edge needed to get a bigger prize.

Forfeitable Welcome Bonus

The forfeitable online casino bonus is a casino welcome offer that works strongly in favor of the player. Like most bonuses, wagering requirements also apply to this bonus, but the only difference is that the player doesn't have to fulfill them.

Another advantage of this bonus is that the players play with their own money first, and only after their deposit is spent, the bonus activates. The player is free to place wagers, and if they win something along the way, they can claim that prize right away without having to complete any other requirements. This could be the best online casino sign up bonus anyone receives as it allows them to claim their prize should they win and have a second go should they lose.

Welcome Bonus Free Spins

As mentioned before, welcome bonuses come in different shapes and sizes, and some of them come in the form of casino free spins bonuses. This type of welcome offer is probably the best welcome bonus for slot game fans as it gives them an additional number of spins to play with. The number of free spins on offer depends on the casino site. In addition, the welcome bonus may extend to a few deposits. This means that you might get more free spins the more deposits you make.

So, you may get 20, 50, 100, 250 free spins or more depending on the online casino of your choice. Like most welcome bonuses, these also come with wagering requirements. The most common wagering requirement for these is to wager your winnings x-amount of times on a selection of games.

Naturally, these requirements vary. However, you should read the terms and conditions of the bonus before applying for a bonus like this. Also, make sure to check the list of selected games because it might not feature your favorite game.

Collecting your Welcome Bonus

The Welcome Bonus is the biggest bonus you can add to your account, this is how you increase your bankroll. It's important to remember that T's & C's apply, so don't forget to check that out.

Welcome Bonus Codes

There are a few ways you can claim a casino welcome offer. Some casino sites will give you the bonus right after you apply for it. Others will provide you with a bonus on your first deposit.

Some will also award you with a bonus on your second, third and fourth deposit. Consequently, the way you receive a welcome bonus depends on the website. This means that some of them will require you to have a bonus code to unlock a welcome bonus.

To get the best welcome bonus, use the above list and apply your own filters. It's the easiest way to get a complete view of what's up for grabs. Find a welcome bonus at the best online casinos with Mr Gamble.

Find the Best Welcome Bonus Casino

Online Casino First Deposit Bonus

When you compare online casino welcome bonuses in your search for the best welcome bonus, you'll find that the best casino sign up bonus is an individual matter. This means that every player has their own opinion of what the best casino sign up bonus includes. This is why we are dedicated to helping every player find what's best suited for them.

So, if you're looking for a welcome bonus that offers 100 free spins, you'll find over 30 websites that do so on your first deposit. If you're looking for a 100% bonus, then you'll have a lot of good offers to inspect.

If you up the ante and look for a 200% welcome bonus, you'll find the number of free spins dwindling and the number of bonus cash rising. However, there are some exceptions to the rule. We encourage you to use our filters to find the best welcome bonus casino for your preferences.

Wagering Requirements and Hidden Terms and Conditions

Like most casino bonuses, welcome bonuses also come with wagering requirements. There's more than one casino online welcome bonus so the requirements will differ between casinos. Some sites will give you a welcome bonus without the need to make a deposit. This is known as a no deposit bonus, and since players don't have to risk their money with it, it's a popular one.

In the same way, the wagering stakes and requirements differ. So, if you're using a bonus without a deposit, you'll probably need to wager the bonus amount of cash or spins a few times to keep the bonus. This is good as you don't risk your own money, and if you lose the bonus amount, you can deposit and play again.

On the other hand, some websites will require you to wager your deposit and the bonus amount to keep the bonus. As most online casinos accept different payment methods, it's no surprise that some of them accept e-Wallets. The problem with this is that some sites will accept first deposits from an e-Wallet for a welcome bonus, and some won't.

All in all, before you just sign up and get the best welcome bonus at an online casino, make sure to read the terms and conditions of the bonus. This will let you know what the wagering requirements are, and you'll know whether you need to wager your deposit or not. In short, you'll see what you're up against.

Welcome Bonuses & Sign Up Bonuses - Deposit and Time Limits

The terms and conditions also include the deposit amount, free spin and free bet sizes. Casinos have placed different maximum and minimum limits on these offers.  At first glance, they may seem restrictive, but their purpose is to ensure that wagering requirements do not get out of hand.

Welcome bonuses usually also have some time limits. However, the offers can change fast, so if you want to use a certain welcome bonus, you should claim it right away. In general, gambling sites give 7 days for wagering casino welcome offers. However, it is always a good idea to double-check the requirements at each casino.

If you do not understand the wagering requirements for welcome bonuses, please contact the casino's customer service. They will be more than happy to help.

Tip: You should also ask customer service about online casino deposit bonuses. Gambling sites often hand them out quite generously, especially for active players.
