How does a 300% Deposit Bonus Work?
A 300% deposit bonus gives you three times the amount that you deposit in bonus funds.
- Open and verify your account with one of the casinos above
- Make a deposit to receive the first deposit bonus
- Use the bonus funds whilst playing at the online casino
It’s important to note that the 300% deposit bonus might not be given on your first deposit. Some casinos will offer this larger deposit bonus on your second or third deposit. If you’re smart, you can deposit less on the lower 100% bonuses - Casino bonuses 100 deposit, but max out the 300% casino bonus offer.
For example, if a casino offers a “300% bonus up to £50”, a £10 deposit will get you an extra £30 in bonus money.
In order to receive the full £50 bonus money, you have to deposit a minimum of £16.68. Which you’re not likely to do, as you’d probably deposit £15 or £20.
Depositing £15 will give you a £45 bonus, whereas £20 will give you the full £50 bonus.
