What is a 300% Deposit Bonus?

Before you can set about your business of claiming a 300% deposit bonus, you first must understand what it is. A 300% deposit bonus sees players earn a deposit match on their original deposit amount of 300%. For example, if you make an initial deposit of £100 when using one of these deposit offers, you will then be rewarded with £300 in bonus funds to use under the bonus terms and conditions. There will often be a minimum deposit amount that you must reach to be given the bonus funds on offer. You may also find that these casino deposit bonuses may be staggered across multiple transactions. This is an extremely generous bonus amount for players. 

You could earn different amounts on your 1st deposit, 2nd deposit and 3rd deposits when using this type of promotion, with some offers even extending deposit match bonuses on your 4th deposit and 5th deposit. The casino will usually put a gaming time limit in place with this type of offer where you will be required to play through the bonus funds within a certain time frame.

Any unused bonus funds will then be forfeited if you do not achieve this within the designated playing time set out from the online casino site you are using. There is also the chance that your online casino could present you with the full 300% on your initial deposit rather than over the course of multiple transactions. Bonuses can vary in size from 100% up to 400% deposit bonuses in some cases!

How can I get a 300% Deposit Bonus?

If you are looking to get your hands on a 300% deposit bonus, the most likely way you do so is through new casino welcome bonuses. These offers tend to be the most rewarding for players outside of those who enrol in a VIP/loyalty scheme with their casino. To enrol in one of these new customers offers, you will need to create an account with your chosen operator, during which you will need to provide a number of personal details. This will include your name, date of birth and email address, as well as your preferred payment method.

You must read the complete bonus terms and conditions before claiming the offer to see any payment method restrictions in place. For example, it is possible that your preferred deposit method may not be eligible for every promotion that you claim, as payment method restrictions are often put in place to stop you from using particular banking methods. 

Once you have created your account, you should then be able to begin using your 300% casino deposit bonus to the rules of the bonus terms and conditions. These deposit offers don’t come around all too often, so they should be snapped up as and when you have the chance to use them. To find deposit offers such as these and more, you should look on the promotions page of the site that you are using. Again, be sure to thoroughly read through the terms of your bonus to look for things such as the minimum deposit amount, wagering requirements and whether your bonus will be given on your 1st deposit or whether it will also apply to your 2nd deposit and 3rd deposits as well. 

You should also be aware of the potential need for a promo code/bonus code at this point. Deposit bonus codes are not uncommon for promotions such as these, and they need to be redeemed at the correct time if they are present. If you do not enter your required promo code or bonus code correctly, you may not be eligible for the initial bonus altogether. You may then contact a customer agent via the customer support team to get your deposit match bonus.

Why choose a 300% Deposit Bonus?

As previously mentioned, it’s not common to get casino deposit bonus deals as big as these every day, so when you do get the opportunity to do so, you should be quick to snap them up. You don’t need to have been a loyal customer for years to get your hands on them either, with new players being able to claim them as part of a casino welcome bonus. Deposit bonus casino deals don’t always reach 300%, and by taking on an offer such as this, you can quickly become familiar with the layout of the site you are using.

You should only take on an offer if you have a real chance of winning real cash, and each of our listed deposit bonus casino deals gives you that. You have a realistic chance of adding to your real cash balance is enough of a reason to take part alone as you get a huge bonus thrown on top of your 1st deposit balance. Your 1st deposit will come alongside a minimum deposit amount, meaning you can gamble only what you feel comfortable playing with and complete responsible gaming in the process. 

We have completed a casino review for each of the casino bonus deals reviewed on this page, so you know you can feel safe playing with a responsible and licensed source that provide fair gaming for all. This bonus money could turn out to be the biggest you receive from operators, making these gaming sessions potentially some of the most lucrative, with the biggest bonus winnings up for grabs. So again, be sure to check the bonus rules before playing to make sure you know everything about the bonus, such as the range of games you can play using it, the playing time you have in which to complete the bonus and any rollover requirements that are included.

300% Deposit Bonus Wagering Requirements

For those who don’t know what wagering requirements on winnings are, they dictate the number of times that you must roll over your bonus balance coming from wins on your initial bonus before it can be withdrawn and added to your real cash balance. These will be included within the withdrawal restrictions and terms of the bonus you are taking on, and there may also be a max withdrawal attached to this. Your wagering contribution can be played on many casino player’s favourite games, though sometimes these will be made up of pre-selected games.

The majority of casinos will require you to complete bonus wagering requirements once you have played through the initial bonus that you have been given. This should come as no shock to players as wagering requirements are now part and parcel of any 300% deposit bonus casino offer that you will look to redeem. In fact, a wagering contribution is to be expected from a deposit bonus casino offer with a lower match deposit bonus than 300%. However, the wagering contribution will likely be lower in line with the size of the match deposit bonus.

Wagering applies to the vast majority of casino offers, and the size of the wagering contribution is at the sole discretion of your chosen operator. It could be anything from 35x wagering to a 50x wagering requirement or even more if they choose to do so. However, it could also be lower if the operator is feeling generous with their wagering contribution terms. Unfortunately, there is no getting away from this with a 300% deposit bonus, so we would recommend going for casino bonuses with lower wagering rates where wagering applies to give you a better chance of coming away with real cash.

300% Deposit Bonus Casino Games

Often, the games you can play your 300% deposit casino bonus on will be pre-selected games that the casino wants you to use. This may be to promote a particular game within their portfolio, or they will pick a typically popular game to lure in a player from promotion pages. Slot games and jackpot games are available within our list of the best 300% deposit casino bonuses, which will certainly impress slots & jackpot players. Online slots are the most popular casino game amongst players, and they can be particularly rewarding, especially when you have such a generous bonus to use on them.

That, too, is why your licensed casino may put restrictions in place when it comes to using your 300% deposit casino bonuses. Pre-selected games are likely but fear not, as all of our bonuses from casinos come packed with entertainment for all who enrol in them. There is a wide range of casino games available to players, and our featured casino deals will allow you to learn which games are for you and which ones aren’t over the course of your time using your 300% deposit casino bonus.
