What is a 300% Bonus?

Online casinos are constantly looking for ways to top the best casino bonuses lists, and 300% bonuses are definitely popular. A 300% bonus is a reward you receive when you register at certain casino sites. This bonus works in a simple way, as the casino matches the amount you deposit with 300%.

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!

Like any other casino bonus, the 300% bonus has wagering requirements you must meet before you qualify to cash out. That's why we recommend reading the terms and conditions first.
