This depends on the casino and offer in question. In most cases, the no deposit bonus will be added automatically so you don’t need to manually enter a code.
If one is required, you’ll see a bunch of alphanumeric digits within the ‘Code’ column on our No Deposit Bonuses page. You must enter this into the applicable field during the registration phase.
In other cases, the casino may ask you to opt-in via a drop-down menu or by ticking a checkbox. Either way, go through the sign-up phase carefully so you don’t miss out!
