What is a bookmaker's promo code? A promo code is a combination of symbols and numbers, which is designed to gain access to bonuses in bookmakers. This special code is required to activate the bonus in the BC – it is enough to enter the promo code in a special column in the form of a Personal Account or during registration, after which the bonus will be available for use. All the current promo codes of bookmakers for today are in a special section of our website dedicated to cricket and online betting.
