The £300 deposit bonus is about as big a bonus as you'll find on offer by UK online casinos so it's hardly surprising that smart players like yourself want to hunt them down and snatch them up!

A sizeable chunk of extra funds like this isn't just reserved for VIPs either! Many online casinos realise that bigger bonuses draw more interest so they will go out of their way to offer large bonus amounts such as £300 even to new players - that's great news for you!

The trick, however, is to make sure that the online casino whose bonus you choose to claim is a reputable, legitimate and trustworthy place to play or you could quickly run into trouble. That's why we've put in all the effort so you don't have to, giving you a list of first class online casinos that you can trust with your money.

£300 Deposit Bonus

Onto the bonus itself, that attractive £300 offer can be dished out in a variety of ways. You may see some sites offering it as deposit XXX, get £300, whereas others may choose to advertise it as a percentage of your deposit amount, such as 100% up to £300. Both of these amount to largely the same thing, just advertised in a slightly different way. If you want the specific details, do check the T&Cs, which have to be transparent by law.

Another common way of getting a £300 bonus is by claiming a welcome package that consists of two, three or more bonuses that add up to £300. These will require you to deposit multiple times, but the benefit is that you can clear that £300 total in increments, meaning you'll get your hands on your winnings that little bit faster!

300% Deposit Bonuses

Percentages of your deposit are the common industry standard for determining how much of a bonus you're entitled to and many players use the larger percentage as a way of pin-pointing the more attractive offers. It's not a bad approach as it ensures you get the most for the money you deposit.

300% deposit bonuses are just about hitting the ceiling of what you can expect to find out there in terms of max percentages. In this case, depending on what you deposit and the maximum stated bonus that's available, you could end up with a sizeable amount to play with. For example, depositing just £100 at an online casino that offers a bonus of 300% up to £300 will result in a bonus of £300, giving you £400 to play with in total!

£300 Deposit Bonus Slots

Many online casinos these days offer more than one welcome bonus in recognition of the fact that players all have unique tastes and preferences when it comes to game choice. As such, it's common to find £300 deposit bonus offers on slots, table games and even live dealer games individually.

In the case of £300 slots bonuses, your bonus amount is valid for use playing demo slot games, though quite often there are a handful of slots that do not allow bonus funds to be used, so check the T&Cs to make sure your favourite slot isn't excluded! Also bear in mind that contributions to the wagering requirements for these bonuses will include slots gameplay only - playing other games will not count at best, and could get your account closed at worst!

£300 Reload Bonuses

Welcome bonuses are not the only way of claiming a nice big £300 bonus of course. In addition to attractive welcome offers and special VIP bonuses for high rollers, you can also continue to enjoy super sized casino bonuses by taking advantage of the site's reload bonus offers, which almost all online casinos have to some degree.

£300 reload bonuses are far from unheard of, especially if you deposit and play a lot. They can be featured as an on-going promotion on the site's Promotions or Offers page or you could even be lucky enough to receive a tailored bonus offer via email. Pick a new online casino, such as any of those featured on this site, and you'll be well on your way!
