What is a 300% casino bonus and how is it calculated?
A 300% casino bonus is a promotion offered by online casinos to attract new players or reward loyal ones. It means that for every euro you deposit, the casino will add an additional 3 euros to your bonus balance, up to a certain limit. For example, if you deposit 50 euros, you will receive an additional 150 euros in bonus funds, for a total of 200 euros to play with.
To calculate the bonus amount, you can use the following formula:
Bonus amount = Deposit amount x Bonus percentage
So, in the example above, the bonus amount would be calculated as follows:
Bonus amount = 50 euros x 300% = 150 euros
Keep in mind that most casino bonuses come with certain terms and conditions that you must meet in order to be able to withdraw any winnings. These may include a minimum deposit amount, a wagering requirement, and a maximum cash-out limit.
What are wagering requirements?
Keep in mind that most casino bonuses come with certain terms and conditions that you must meet in order to be able to withdraw any winnings. These may include a minimum deposit amount, a wagering requirement, and a maximum cash-out limit.
For example, if the wagering requirement for the 300% bonus is 40x, you would need to wager the bonus amount (150 euros) 40 times before you can withdraw any winnings. This means you would need to place bets totalling at least 6,000 euros before you can request a withdrawal.
It’s important to read and understand the terms and conditions of any casino bonus before you claim it, so you know exactly what you are getting and what you need to do in order to take advantage of it.
