What Is a 300% Deposit Bonus Casino Offer?

A 300% deposit bonus is a type of online casino promotion that awards every user who deposits funds with an amount that’s 300% bigger than their deposit amount. For example, if you deposit £100 and activate the bonus, you’ll get £300 as a bonus and have a total of £400 as your starting amount. Many non UK casinos feature this type of promotion.

If you see a platform offering a 300 casino bonus, that can also mean you’ll receive up to £300 as a bonus. Therefore, make sure to check which one it is to pick the right promotion for you. Some of the best casino bonus platforms often offer more than that on your first deposit.

Clearing the Wagering Requirements on 300% Deposit Bonus Slots

Almost every 300 deposit bonus casino has wagering requirements, which indicate the number of times you need to wager through your bonus amount to be able to withdraw your bonus funds. Even many non Gamstop casinos feature this type of requirement. Here’s how it works.

Suppose you get a 300$ no deposit bonus (even though no deposit bonuses are usually much lower). Once you open the T&Cs section, you’ll notice, say, 30x wagering requirements, meaning you’ll have to wager an amount that’s 30 times bigger than your bonus amount. In this case, that’s $9,000. Check out the list of great platforms with a no deposit bonus not on Gamstop, to learn more about this type of promotion.

Many other promotions also feature wagering requirements. Even bingo sites 300 deposit bonus is subject to this term, meaning you need to meet it to cash out your bonus money.
