An overview of the 300% online casino bonus

300% Welcome Bonuses

It doesn’t matter if you’re new to the world of online gambling or have been playing for some time, it’s undeniably important to make your money go as far as possible. You may perhaps choose to play with stakes that allow you to extend your overall iGaming session or, instead, you might opt to risk it all on one big win. However, there is something you can do to enhance your overall chances of landing a substantial cashout, regardless of your preferred style of play – make use of a welcome bonus.

Now, online casino welcome bonuses come in all sorts of shapes and sizes. Whilst most sites offer a 100% deposit match to double your initial bankroll there are some that are immensely more generous. Imagine being able to quadruple your deposit. You’d be able to play even more of your favourite casino games and even try out a few other new and intriguing titles without having to worry about spending more than you’re willing to risk.

To highlight how beneficial a 300% deposit bonus can be, allow us to provide a hypothetical example. Let’s say a casino were to offer a 300% up to €100 bonus. If you were to deposit €100, the site would then add an extra €300 to your account balance, ultimately giving you four times as much money to play with.

Of course, because these offers are so valuable they’re not overly common and may be capped to a lesser deposit amount but if a casino is willing to offer a 300% deposit bonus it’s worth taking a closer look. However, we do advise that you first familiarise yourself with the site before committing to a real money deposit, which you can do by reading our casino reviews. As ever, we aim to provide you with all of the relevant tools to make an informed decision. That’s why each NetEnt casino we highlight undergoes a stringent review process to ensure its security and trustworthiness. It doesn’t matter if there’s a huge offer on the table, if the casino fails to meet our security requirements we won’t give it a recommendation.

Where Can I Claim A 300% Welcome Bonus?

What To Look Out For When Claiming A 300% Welcome Bonus

Generic money imageAs lucrative as a 300% casino bonus might initially appear, there are certain factors that you should consider before spending your hard-earned cash. Many of these are found within the bonus terms and conditions and as such we recommend you carefully read the fine print beforehand so that you’re fully aware of any potential obstacles.

In most cases, you’ll come across similar Ts & Cs just like when claiming any type of casino bonus. Still, certain terms can be indicative of a predatory bonus. Therefore, you’ll find an overview of some of the most important Ts & Cs you’ll want to look out for below.

  • Wagering requirements: If you’re claiming a welcome bonus for the first time, it’s important that you understand how online casinos typically award the additional funds. More often than not, any extra money you receive as part of a welcome offer is credited in the form of bonus funds, which means you cannot instantly request a withdrawal for the full amount. You must first convert any bonus funds into real money by wagering your bonus amount a specified number of times. As such, the higher the wagering requirement the more difficulty you’ll face when looking to convert your funds. We advise that you look for offers with wagering requirements somewhere in the region of 35 times your bonus as these give you the best chance of requesting a withdrawal.


  • Minimum qualifying deposit: Another term you’ll need to watch out for is how much you will need to initially deposit to qualify for the advertised offer. Most sites require a minimum deposit of €10 to claim a welcome bonus but this does vary from one casino to the next. Therefore, carefully pore over the terms and conditions to see how much you’ll need to deposit to be eligible so as not to miss out.


  • Payment method eligibility: Although most online casinos provide multiple payment methods that you can use to perform financial transactions, they may not all be eligible for use when attempting to claim a welcome bonus. Certain banking solutions such as Skrill and Paysafecard are often excluded from casino bonuses, meaning you cannot use them to trigger the advertised offer. Instead, you may need to use an alternative method if you wish to take advantage of any extra funds and/or free spins.


  • Validity period: From the moment you activate a 300% welcome bonus there will be a timeframe in which it must be used. During this period you must meet the attached wagering requirements or face the prospect of your bonus becoming forfeit. Generally, most casinos provide a 7-14 day window so this shouldn’t be too much of an issue but, again, this may differ from one site to the next. If you plan on playing over several sessions we advise you to look for a bonus with an extended validity period.
