When you deposit with a code in mind, the moment that matters is the cashier screen: after choosing your payment method and amount, look for the promo code box beside the deposit summary. Type the code there before you hit confirm, because the deposit triggers the offer — and a deposit made without its code usually cannot be matched afterwards.
Before confirming, run a quick three-point check. First, make sure your amount clears the minimum the code requires, since even a dollar short leaves the offer unactivated. Second, check that your chosen payment method is eligible, as some offers exclude specific options. Third, re-read the code letter by letter, exactly as it appears in the asino casino bonus codes list, because a single wrong character fails silently.
If everything matches, confirm the deposit. The credited bonus and a confirmation line in your transaction history prove the code worked, and you can head straight to the games.
