Biggest Casino Bonuses

Best

Let’s face it, one of the best features of the online casinos are the large free money bonuses they offer for both new and existing customers. The free bonuses for new players are the biggest ones, although some online casinos offer pretty sizable chunks of free chips for their existing customers, as well. Below you will find the list of the latest big online casino bonuses, arranged from the largest promotion to the smallest. Further down you can read more about the casino bonus, how it works and some of the general requirements.

Keep in mind that all of the online casinos on our bonus list are part of our best online casino list, so you can play at any of them with confidence. We recommend you start from the biggest bonus and come back later to work your way down the list of the casino bonuses. The online casinos are perfectly fine with you opening accounts at other casinos to take advantage of the new customer bonus, but be aware that opening multiple accounts at the same casino is a breach of terms, just to warn you of the dangers. If you have played through your bonus already, simply open an account at a different casino and take advantage of their first-time customer free bonus.

$10,000One of the most popular casinos on the internet, Las Vegas USA give new customers up to $10,000 free, based on 400% of your first deposit you make with the casino. Thanks to this updated offer, now players can join one of the top casinos, while enjoying one of the biggest bonuses around.
$7,777 + 300 free spinsAnother enormous bonus with a ton of free spins to boot. While SlotoCash Casino offers slightly less in terms of bonus money, it certainly makes up with the additional 300 spins every new player can qualify to receive with their deposits. The welcome bonus comes in five parts, so you don;t have to deposit big to get match chips and free spins. And the fact that the slots games here are amazing (there is a reason for the name), is just icing on the cake.
400% + 50 free spins

(Exclusive bonus, must use code 'BUBBLE400')

An amazing custom bonus for our readers, Rich Palms casino will match your first deposit with a 400% of their own, and will give you an additional 50 free spins on the Bubble Bubble 2 video slot! With very low 30x playthrough, this exclusive casino bonus is among the best you will ever come through. Don't take the smaller welcome bonus advertised on their website, use the code above and quadruple your bankroll right away.
$10,000In a similar fashion, players will get 400% match to their deposit, up to $10,000, at Vegas Casino Online, as well. All you have to do in order to claim this exclusive bonus is to use bonus code '400BONUS' and you can get the top amount, instead of the $3,000 advertised on their website. The required playthrough is 40x for the first level of their reward program, but if you get a larger bonus you can reach their Diamond level when you play with your bonus and qualify for the 30x lowered playthrough requirement before bonus cashout.
$9,000The bonus at this fresh RTG casino is based on a 300% match of the customer's first deposit, which is why it's not higher up the list, but the actual free money you can get is certainly up there. And once you cash in on the signup bonus, you have the chance to claim a lot more offers, most of them giving you the chance to double and triple your deposits. If you are looking for a big casino bonus, Lucky Hippo will give you quite a bit of them.
500%If you want to get the most percentage-wise bonus from the online casino, you must go with High Country. This RTG-based casino will give you five times your signup deposit, the highest match bonus offer among the top casinos. The reason we did not rank High Country higher (wink) is because the max bonus amount tops out at $2,500, which is lower than most. But with an additional 50% cashback if you lose from your welcome bonus, this casino is a no brainer for new players.
$5,000At Old Havana Casino you can double your first deposit all the way up to $5,000 in free casino chips. The minimum deposit to qualify is only $20 and the playthrough is 40x before you can cash out your bonus money.
$3,000The $3,000 free money at the Bovada casino is based on eight separate bonus offers that new customers can take advantage of, each giving you a 100% match bonus of up to $500. Use bonus code SLOTS500 to get the free casino bonus. The offer carries a low 25X rollover requirement in the casino before the chip purchase, bonus amount and any winnings can be cashed out.
$3,000Enjoy over 300 video slots with the 150% match on your deposit at Sun Palace, all the way up to $3,000. The play through needed to be met before you can withdraw your bonus is 40x bonus and deposit.
400%Lucky Red is another online casino offering a great 400% match bonus on your first deposit, up to $4,000 in free casino money. Use promo code LUCKYRED400 to take advantage of this great promotion. The playthough requirement is 30x deposit+bonus before you can cash out your free chips, well below the industry standard.
$2,000There are actually two bonus offers for new customers at High Noon. The first one is no deposit bonus and will give you $60 in free chips to try the casino, the bonus is indeed cashable so you risk nothing and stand to gain all your winnings. Use bonus code SIXSHOOTER for this no deposit bonus. And if you use bonus code HIGHNOON200 you will get 200% match of up to $2,000 free. The wagering requirement is only 25x bonus+deposit before withdrawal.
200%A great bonus offer from Aladdin's Gold casino - claim 200% on every single deposit you make for the first 7 days after you open an account. And the best part - there is no limit on the bonus amount! The deposit+bonus money must be wagered 30x before a withdrawal.

Biggest Online Casino Bonuses 2021 - Compare the latest casino bonus offers from top online casinos. We have handpicked the best online casino bonuses. The biggest casino bonuses aren’t always the best. Gambling sites make the offers significant, so they are attractive, but keep in mind to max out the offer you have to deposit more. Look at the match rate and the rest of the terms and conditions before you make a choice.

Intertops Red Casino Bonuses

A word about how the online casino bonus works and what you should take into consideration when you claim your bonus. First thing you need to understand about the bonuses offered by the online casinos is that they are oftentimes based on your initial deposit, rather than a fixed amount of money. Fortunately for you, our leading casino bonus is very generous both in terms of actual amount of money ($10,000) and percentage of your deposit (400%), as well. These are the best casino bonuses, when both the amount and the percentage are very high. But in general, make sure you first see at what percentage of your deposit is the actual bonus based on. For example, two online casinos may advertise the same $3,000 bonus for new customers, yet one of them is basing this on 200% match and the other on 150% match of your initial deposit. Clearly the one offering the 200% bonus is a better value, since you’d get more money for the same deposit there. We have noted the percentages of the bonuses in the table above, to make it easier for you to compare.

Another very important part of the casino bonus is the playthrough requirements, also referred to as wagering requirements or rollover. If the casino simply doubled your money without any need for those wagering requirements, you could simply take the bonus and withdraw your money, without ever playing the games. Clearly, it would be insane for the casino to do so. The playtrough requirements re in place to avoid this. What are the playtrough requirements and how they work? Simple – if you take advantage of a casino bonus you are required to wager the deposit+bonus amount certain number of times before you can withdraw your bonus money. Note that you only need to wager it, regardless of whether you win or lose and playing casino games, such as slots, would quickly take care of the rollover needed.

The playthrough requirements apply to the bonuses at all online casinos and is not something that you can avoid. However, some online casinos will offer smaller wagering requirements than others, giving you the chance to withdraw your bonus winnings much quicker. We have also noted the playthrough for each bonus at each online casino in the table above. If there are two identical casino bonuses, the wagering requirement could be used as a tiebreaker. Word of caution, avoid any playthrough that is over 40x, even though the industry standard is 50x, there are plenty of good online casinos offering much lower bonus playthrough requirements before cashing out.

Of course, at this point many people would begin to wonder why would the casinos offer such promotions to players. True, at first look, the casino bonus appears to be a losing proposition for the casino itself – giving away money to people in exchange for nothing seems like a quick way to go bankrupt in any business. After all, when was the last time you visited a regular casino and the host just handed you a wad of money to play as your heart desires?

The truth is that the online casinos have a much lower overhead compared to the traditional brick & mortar casinos. That alone allows them to take risks with some of those savings. At the end of the day, the online-based casinos can make the same profit a traditional one would, even when offering such amazing perks, unmatched offline. But this is not the sole reason.

The bonuses, the welcome bonus in particular, has long been one of the best tools for the casinos to attract customers. After all, the higher the casino bonus offered, the better chance the player would sign up with this website, rather than go to the competition, of which there is always plenty. And since the casino bonus is tied to a deposit made, it virtually guarantees to the casino that they are investing the bonus money, rather than just giving it away.
