Other promotions don’t require a code, but instead ask you to ‘opt-in’ to receive them. This usually means that you will simply select your bonus from a dropdown list or Blackcoin something similar on the site’s cashier or promotions page or when you make an account. The usual way to claim a promotion on a casino site is to use a bonus code, which will be a series of numbers and letters you can input on the site to grab your reward. You will need to enter the code when you make a deposit, it could be on the promotions page or during the signup process if it’s a welcome bonus. Usually, though, casino sites don’t need to have you download a dedicated app.
