To apply a bonus code when making a deposit at an online casino, the process is generally simple but may differ slightly from one casino to another. At n1 casino, for example, during the deposit process, there’s usually a field where you can enter the promo or bonus code. After you enter the code and make the deposit, the bonus will typically be applied automatically to your account. Make sure the code is correct, and check that the casino has activated the bonus by reviewing your account balance or bonus section. Always verify the terms and any wagering requirements for the bonus.
