Promo codes such as 1XLUX777 serve as activation tools within the bonus program. These codes are combinations of letters and numbers that unlock access to predefined bonuses. Each code is unique, and its application depends on the specific promotional conditions at the time. The bonus structure may differ based on campaign rules, and the format of the reward—whether it's bonus money, free bets, or spins—will also depend on the promotion tied to the code.
