What is a 300% Bonus?

Whereas a 100% bonus will double your deposit and a 200% bonus will triple it, a 300% bonus will go even further by quadrupling your deposit! If you are fortunate enough to find an online casino with an offer of this type, chances are it is being presented as a one-off welcome bonus for new members.

This kind of offer is far less common than the standard 100% bonus, but with the sites in the area competing with one another to provide the best casino bonuses, do not be too surprised to find more and more casinos giving out 300% deposit bonuses to their new members.

Bear In Mind Bear In Mind

Usually, these bonuses are available for a short time or upon certain conditions (like signing up), and they have terms and conditions you must meet before you are eligible to cash out.

For instance, you deposit €/£20 at your casino of choice to receive a 300% Deposit Bonus Boost. This means that you'll receive €/£60 plus your original deposit of €/£20 to play with. This bonus can be spent on certain games that are recommended by the casino.

Depositing €/£20 at a 300% casino means you get €/£60 in bonus funds. You’ll get to play with €/£80!

Offers which are as generous-seeming as a 300% deposit bonus will never come without a few strings attached, so take a look to see what wagering requirements or time limits might apply to the offer before you commit to depositing. The basic idea behind a 300% bonus is simple enough, as all it means is that your qualifying deposit will be multiplied by 300%.

So, for example — imagine depositing €/£20 at an online casino: if this triggers a 300% bonus, then in addition to the €/£20 that you've just put in your account, you will be given a bonus sum of €/£60 — amounting to a total of €/£80 for you to start placing bets with.

In some cases, the casino might allow the bonus funds to be used only on participating top casing games. Whether or not these are the sort of games that you personally prefer playing will depend partly on the online casino in question and your own tastes.

How to Claim Welcome Bonus with 300%

The exact manner in which you claim a 300% bonus at an online casino will vary depending on the site. Still, there are a few details that you can expect to find involved with the bonus, no matter which casino you choose.

For one, the bonus in question is very likely to be a welcome offer intended specifically as a one-time gift for new members, so here is our quick guide to claiming a 300% welcome bonus:

  1. Check out our top recommended list and pick a 300% casino that suits you.
  2. Register a new account at the casino site.
  3. Read and understand all the bonus terms and conditions.
  4. Pick your preferred payment method and make a qualifying deposit. Then enter the bonus code if available.
  5. Visit the game lobby and play any of the eligible games.
  6. Complete the bonus wagering requirements and other terms of use.
  7. Cash out your bonus and winnings.

Take Advantage of 300% Bonus: Top Tips

Once you’ve chosen a gambling site with a 300% bonus, then you will almost certainly now be wondering about the best way to put this offer to use to make sure that it is not wasted. With this in mind, here is our overview of the nitty-gritty when it comes to both finding and getting the most out of a 300% deposit bonus.

Different Types of 300% Bonus

While it might seem that one 300% casino bonus will be much the same as another, in practice, there are several variables involved. For example, some 300% bonuses might also come with free spins, while others will consist only of bonus cash. The maximum size of the deposit will be another factor to take into account.

<strong>Maximums Aren’t Obligatory!</strong> Maximums Aren’t Obligatory!

Of course, if you find a 300% bonus gambling site with a very large maximum bonus offered, there’s no obligation to deposit enough to earn that max. Always pay within your means, ultimately it’ll lead to a more enjoyable casino experience.

In addition, an increasing number of online casinos have adopted a “wheel of fortune” approach to welcome bonuses. A new member will spin a wheel and win a randomly chosen bonus. This might conceivably take the form of a 300% casino bonus, but it could also be something smaller, like a 100% or 50% bonus. On the other hand, it might turn out to be something even bigger. These days, even 400% welcome bonuses are not unheard of.

Finding The Top Casinos with 300% Bonus

Top10 already recommends some of the best online casinos in our list of 300% deposit bonus gambling sites. That said, here’s a peek at what we looked out for when choosing the top 300% bonus casinos.

A casino bonus 300 percent rating is not the ‘be-all and end-all' of an online casino, and you will also want to take into account other factors, such as the games on offer, whether or not your preferred payment methods are accepted, the size of the accepted withdrawal limit, and how reliable the customer support might be if you run into a technical hitch. The good news is that there is nothing stopping you from registering at multiple casinos, meaning that you can take advantage of more than one 300% casino bonus!

<strong>Check the Terms of Use</strong> Check the Terms of Use

Another difference between each gambling site with a 300% bonus is that different sites will have different terms and conditions. Remember to pay close attention to the “small print” to make sure that the casino you are signing up for is right for you.

Additional Bonuses at 300% Casinos

When it comes to casino bonuses, the welcome bonus — even a welcome bonus as large as 300% — will typically be only part of the story. Most online casinos offer ongoing promotions, and these tend to vary significantly from casino to casino. Some will be handed out daily, others weekly, and still others will be seasonal. They might provide free spins, or they could be “reload bonuses” that offer match bonuses on deposits (generally never up to 300%, of course — expect these to be lower sums, like 50% per week with a modest cap).

Online casinos sometimes come with casino VIP schemes that can earn you additional perks so long as you keep placing wagers on the games. So, when you select a 300% bonus gambling site to sign up at, do not forget to take a look at the other bonuses and promotions that are on offer. You might well be able to bag yourself some free spins and other perks on the side.

If You Need Help: Customer Support

The terms and conditions attached to any casino bonus can be hard to get your head around, and if you are concerned about technical issues, it will be a good idea to make sure that the 300% bonus gambling site you are signing up for offers satisfactory customer service.

Check the “contact us” page or equivalent to see what methods of contact are provided (phone, email or live chat) and which time zones the support team is available. This will help you keep peace of mind when you have fun with your 300% bonus.

<strong>Using</strong><strong> Unlicensed Casinos</strong> Using Unlicensed Casinos

It goes without saying that licensed casinos are far and away the most reliable and, at the end of the day, the only ones worth your time. If you don't see full license information at the bottom of the site, then avoid signing up no matter how tempting the offers might be: there is no guarantee that you will even receive your 300% casino bonus at an unlicensed casino.

Things To Keep in Mind: Hidden Costs and More

As any savvy casino gamer will be fully aware, bonuses never come for free — even if online casinos sometimes tend to imply the opposite. To start with, if you want to claim the maximum 300% deposit bonus, then you will typically need to deposit a very large amount of money. So put serious thought into settling for a smaller amount that will require a smaller deposit (you will still be granted 300%, after all).

Another thing to watch out for is that casinos that purport to have 300% bonuses might actually provide something quite different. For example, some casinos claim to have 300% welcome bonuses, but when you look at the details, these turn out to be split over two deposits: 100% on your first deposit, followed by 200% on your second deposit.

This might still be a perfectly good welcome bonus — but since it involves making two deposits, it is obviously very different from winning a 300% casino bonus in exchange for a single deposit.

Wagering Requirements

Any casino deposit bonus will almost certainly come with wagering requirements, and 300% deposit bonuses are no exception. Any wagering requirements attached to the bonus will need to be fulfilled before you can withdraw your bonus funds.

So, for example, let's say you've picked up £/€100 worth of funds with a wagering requirement of 30x. This means that you will need to wager at least £/€3,000 to fulfil the requirements.

There is also the possibility that you have ended up with what is called a “sticky bonus“, in which case the wagering requirements will also include your initial deposit. So, if you deposited £/€25 for a 300% bonus that earned you an additional £/€75, you will still need to wager £/€3,000 to fulfil the requirements on the £/€100 total.

Always Check the Game Contributions Always Check the Game Contributions

Not all wagers will contribute to the fulfilment of your wagering requirements. Some games contribute; others do not. So, if you want to fulfil your requirements, check to make sure the game you want to play will contribute before you place your bets.

Cash-Out and Time Limits

Any casino bonus will typically come with some sort of time limit on when the funds can be used. Often this will be a space of seven days from receipt. If you have not wagered your bonus money by then, it will be deducted from your account. Casinos also tend to put limits on cashing out your winnings: your withdrawal sum will need to fit into an accepted range before it can be processed.

What Games Can You Play with a 300% Casino Bonus?

There is a chance that your newly claimed 300% deposit bonus will be limited to a specific set of games. Some sites restrict their welcome bonus to slot games, for example, while others will only allow you to use it on the live gaming section. Once again, make sure you check the terms and conditions of the online casino in question before you make your first deposit so that you know exactly what you are obtaining.

Pros and Cons of a 300% Welcome Bonus

As we have shown throughout our article, while a 300% welcome bonus casino may sound like a dream, there will always be strings attached. It is a good idea, then, to weigh up the positives and negatives of the bonus before you commit.
