How We Review Casinos
When reviewing casinos that offer bonus codes, I look at how valuable and fair the promotions are. A great bonus code should give you actual value—whether it’s free spins, bonus cash, or cashback. I also check the wagering requirements, making sure they are reasonable and not designed to trap you!
Once happy, I’ll then look at other aspects of the casino, including their game selection, payment options, customer support facilities, and more.
How To Use Your Bonus Code
Once you’ve decided which bonus code you’re going to use, you need to first sign-up at the appropriate casino. Depending on the code you’ve chosen, you may need to enter it when making a deposit—while, at other sites, you’ll be able to navigate to a special page where you can input your code without needing to make a deposit.
