What is the promo code thing about?
I do not understand where you can get the promo code for the boss coins. Furthermore, what is the promo code?? Please answer as soon as possible.
Hello mate, promo code can be a single word on a phrase that a manager can use to earn some more boss coins...from time to time promo codes are introduced/revealed via the social media of the game....you have just to follow the media and maybe you can get lucky....
