Online Casino Sign Up Bonus

Online Casino Sign-Up Bonus deals, which are also known as Welcome Bonuses, can earn you thousands of dollars when the wagering requirements are met. Hence, upon signing-up to a gambling site you'll be given one of the best online casino bonuses in the history of your whole iGaming experience. Fundamentally, the most important thing to note when playing at online casino sites is that sign-up bonuses tend to be given to players when they’ve completed the registration process and made a deposit. Unfortunately, you can only get this type of bonus once per casino site (hence the name). Thus, before you go ahead and sign up to an online casino site you should be sure of the choice you’re making. Our experts at CasinoTop10 recommend that you seek to find the highest sign-up bonus before registering your details with a particular online casino site because in retrospect you’re only going to get one shot at gaining the top online casino free sign up bonus. 

Match Bonus

A Match Bonus is one you'd receive at an online casino where your deposit is matched by a fixed percentage. For example, if you deposit $ / € 100 and the bonus match percentage on offer is 300%, you will be given $ / € 300 in return. Likewise, if you deposit $/ deposit $ / € 100 and the bonus match is 400%, you’ll be able to receive $ / €400 in return. Whilst cashing in on a Match online casino bonus is great and all, a casino will generally impose a limit on how much they give their players. Hence, you’ll generally see promotions stating things like 150% Match Bonus up to €/$/£ 1,000 in order for the casino to express its limit. There are different percentage match bonuses at online casinos on offer, a casino could offer you 20%, 50%, 100%, 200%, to 400% of your original deposit. There are some maximum bonus limits in order to prevent people with large sums of money who want an equally high sum back for free. There are also minimum deposits required as well, from $10-$30 typically, that you need to deposit in order to claim your bonus. It’s common to find an online casino with free signup bonus and real money matching your deposit.

Sticky Bonus

A Sticky Bonus is given to you in order to place bets at an online casino, but which essentially not yours for the keeping. Nonetheless, collecting this type of bonus still has its own advantage as it will allow you to play the game before you actually make a deposit to the site. The pretty wonderful thing about the sticky bonus is that it does not carry the terms and conditions that many standard casino bonuses adhere to which make it a bit of a bonus rebel. Sticky bonuses are a superbly efficient way of improving your game and starting it in the best way possible – with a huge initial balance to enjoy. Once you have successfully met the wagering requirements, you will then be able to withdraw your winnings from your account. However, the sticky bonus money which was given to you initially will then be removed from your winnings. The rest is yours to use as your heart desires! 

Loyalty Bonuses

Loyalty Bonuses are a bird of another feather when compared to other bonuses. Commonly, these types of bonuses are given to loyal customers who have continuously kept playing at the same casino site for months or even years. In essence, these exclusive casino bonuses are used in order to reward players for gaining a certain amount of points and moving up in the casinos standings from, for example, gold member to platinum member. Also, members receive a diversity of exclusive bonuses depending on their membership status. Common Loyalty Bonuses are ‘free spins bonuses’ and ‘monthly match’ bonuses which are similar to many of the welcome bonuses that players initially receive on signing up at a new casino.

Deposit Casino Bonuses

Online casinos like to show their players how much they're appreciated by giving each and every one of them a Deposit Bonus. When making a deposit of a certain size, the casino will reward you for doing so by giving you a percentage of the money, on top of your deposit. Many have dubbed this a casino's version of a discount because if you deposit $100 and the casino gives you an extra 10% on top of that, you end up with $110 even though you only paid for the first $100, you get to gamble with $110.

No Deposit Casino Bonuses 

Sometimes you might want to test the waters a bit before committing yourself to a certain online casino. And luckily, nowadays you’ll also be able to find a number of No Deposit Casinos which offer no deposit bonuses! A No Deposit Bonus, which is also known as a Free Money Bonus, is one that you’re typically able to receive by just signing up to an account. In this case, making an initial deposit is not necessary. Yet, if you’re interested in this type of Bonus, you should take the time to read the fine print as the online casino might impose high wagering requirements and irritating withdrawal limits as a result of offering you a no deposit online casino bonus. Hence, even though the No Deposit Bonus you’re looking at might seem appealing, you might be barking up the wrong tree especially if you can afford to make an initial deposit. 

As you wade through various sites, don’t despair! You will surely find a handful of top online casinos with a free signup bonus and no deposit required and relatively low wagering requirements.

Free Play Casino Bonuses

Free play bonuses are quite similar to no deposit casino bonuses but they won’t allow you to withdraw any of your winnings like you could with the no deposit bonuses. The free play bonuses are usually reserved for special offers and new casino games, something that the casino would like to promote. The free play bonuses usually come with a time limit or a playing limit. This means you only have a certain amount of time to play or a certain amount of money to spend before the bonus runs out and you’ll need to deposit money to play further.

Free Spins Bonuses

The free spins bonuses are unique in that they really only apply to a single genre of games, the online slot machines. These are usually given to players when there’s a slot tournament on and the casino would need to drive interest in the game being played. They would offer patrons the chance to play the game, have a few free spins of the reels, and see what the game is like. Nonetheless, before you accept a free spins bonus, you will have to read the fine print as some are only applicable for a certain amount of spins or a certain amount of time and others may not include any money, you’ll just have to see. Free Spins can some be part of the welcome package and are highly recommended as some of the best online casino bonus deals here.

The Refer-a-friend Bonus

As the name implies, the Refer-a-Friend Bonus is given to a player once they send an invite to one of their friends by email. Essentially, this is a particularly pleasing top online casino bonus as you’re usually able to get quite a lot of bang for your buck. All you merely have to do is tell your friends, family or colleagues about the online casino and if they choose to sign up to the casino you’ve recommended and use you as a reference, you’ll receive a percentage of their first deposit. Nothing could be simpler.

Cashback Bonus

You will find that different online casinos have different definitions and version of the cashback bonus. However what they have in common is that they are a regular promotion, and that you will get money back from the online casino. One version of this bonus is for existing customers, similar to a loyalty bonus. A casino will look at your activity and how often and how much you are betting, and then give you a small percentage of your losses back to you in the form of a cashback bonus. Another version is that you play first with your deposit instead of a bonus with a wagering requirement. If you don’t win, then you get a small cashback bonus back.

You Must Meet the Different Criteria to Cash in on Top Online Casino Bonuses

Like most offers and promotions that can be found all over the world wide web. Generally, you’ll need to meet certain criteria in order to be eligible to cash in on a top online casino bonus. If you have absolutely no idea what these criteria are, let us help you out there. There are namely 3 major factors that will enable you to cash in on a superb bonus deal. These are outlined below:

The 3 Major Factors That Enable You to Claim Top Casino Online Bonuses

1) You must be of legal Gambling Age 

The first is that you’ve reached the legal gambling age in the country you're playing from. In most cases, the legal gambling age is 18 or 21. However, in some cases, this may differ due to legislation in place that governs online gambling in the particular country you’re residing in. Before signing up to an online casino, it is always advisable to check the legal gambling age to ensure that you're not breaking any laws.

2) You Need to be a Registration Customer of the Online Casino

The second factor involved is, of course, that you’ve completed the registration form and signed up at the online casino that’s offering the casino bonus you’re after in the first place. Like any other online account you set up, you will receive an email to confirm your registration.

3) You Must Make a Deposit at the Bonus Casino

Wagering Requirements & Fine Print Applicable to Online Casino Bonuses

Before you go ahead and use any of the bonuses offered to you by an online casino, you should always make sure that you’ve read the fine print and know what the wagering requirements are. Collecting your winnings after receiving a Bonus will sometimes entail meeting the wagering requirements. Below find our video and text explain how wagering requirements work at online casinos. 

What is a Wagering Requirement?

The wagering requirement is something you will come across when claiming a casino bonus deal. It simply equates the amount you must bet in order to be able to withdraw your bonus winnings from your account. Typically, the wagering requirement is a multiple of the bonus given and is indicated by a number and an ‘X’, for example, 10X, 30X etc. The total is the amount of money which must be wagered before you can withdraw your winnings from an online casino.

This means that if you’ve deposited $ / €100 and the wagering requirement is 30X, you’ll need to make $ / € 3,000 in wagers before you’re able to cash out. This doesn’t mean that you need to have $ / €3,000 as every bet you make, whether you win or lose, will count towards your wagering requirements. For example, if you’ve played a slots game and have bet $ / €1 on each spin for a total of 10 spins and you manage to win $ / € 8 and lose $ / €2, you would be still contributing $ / €10s to the wagering requirement. In addition, if you continue to play on another game such as roulette or continue to play slots and you bet $ / € 1 on each spin for a total of 10 spins and manage to win $ / € 1,000, you’ll be up by $ / € 990 but you’ll still be contributing $ / € 10 towards your wagering requirements. This amount will depend on the casino and the country you’re playing from.

Wagering Requirements Based on Deposits & Casino Bonuses

casino bonuses

Some casinos do not only apply their wagering requirements to the amount you receive as a bonus, but also to the amount that you choose to deposit. This is known as D (Deposit amount) B (Bonus amount) wagering. For example, if you deposit $ / € 300 and a bonus of $ / €200, the wagering requirements will be set higher at the casino. Provided that the wagering requirements are D B, the wagering requirement would be marked as 30 X B, with ‘X’ being the deposit amount and ‘B’ being the bonus amount times 30. Supposing that you’ve deposited the amount of $ / € 300 and received a bonus of $ / € 200, you’d then have to plus the two amounts and times the total by 30 which would mean that the wagering requirement will then have to be a total of $ / € 15,000.

If you’re new to the iGaming scene, you should be aware that most players will not take a gamblers bonus of less than a 100% match if the casino states that it has a D B wagering requirement on it. If a casino offers you an online casino bonus of 20% on a $ / €100 deposit with a wagering requirement of D B then the requirement would be $ / € 3,600 with the majority of that being the player’s own money. Bear in mind that most casinos have higher wagering requirements on sign up bonuses and no deposit bonuses since in retrospect these are the ones which are mostly taken advantage of.

Game Contribution Percentages & Wagering Requirements

Keep in mind that some games will contribute different percentages in wagering requirements and not all games count to meeting through these requirements.


Slots may count as 100%, so a bet of $ / €2 would count as $ / € 2 of your wagering requirement.

Roulette may count as 50% so if you make a bet of $ / € 2, you’d only be contributing $ / € 1 towards your wagering requirement.

Video Poker might count as 10% of your wagering requirement, so that would increase your requirement from 30X to 300X which in hindsight would make a massive difference to your wagering requirements. If you receive a $ / € 50 Bonus and play a video poker game which makes a 10% contribution to your wagering requirement would increase from $ / € 1,500 to $ / € 15,000.

Casino Bonus Terms indicate which Games Offer the Best Percentages

casino online bonusesAlways make sure to read the terms carefully, in order to be able to evaluate which games you can play on to meet the wagering requirements in order to be able to cash out. Some casinos have a condition on the games you choose to play and how you’re allowed to meet the wagering requirements. Some casinos have a condition whereby if you play any game with a wagering requirement which is of a less % than another game you’d still be contributing the less % despite the fact that it might have a higher wagering requirement percentage on it. For instance, if you play a slots game that has a 100% wagering requirement and video poker which has a 10% wagering requirement, the wagering requirement on the slots game will be 10% rather than 100%.

Some casinos will void your gamblers' bonus and winnings provided that you try to withdraw the money at one go. If you need help in determining the amount you need to wager, we recommend that you have a look at CasinoTop10’s Bonus Calculator, where you’ll be able to input the values representing the deposit amount, percentage deposit bonus, wagering amount and game contribution percentage.

Remember: The Largest Bonus Isn't Always the Best Online Casino Bonus

As mentioned above, different casinos have different wagering requirements. The largest online casino bonus will, in all probability, have the most stringent wagering requirements attached to it. Therefore, unless you're an extremely frequent or high stakes player, there is a good chance that you’ll find it difficult to fulfill the wagering requirements for these very large bonuses. And that's why the largest bonuses aren't always the best online bonus. Be sure to do your research and try to gauge whether a bonus has beatable wagering requirements. This way you won't be disappointed and avoid the worst-case scenario - spending valuable time and money clearing a top online casino bonus but then not being able to claim it.
