Welcome to the forum. I just decided to check the promo code, firstly, after registration, a confirmation letter does not arrive by mail, although a notification has surfaced on the casino's website that it has been sent, secondly, when using the specified OP promo code, I receive the message "SUCCESS Success! You've received 0 coins", perhaps the promo code is no longer valid, but then there would be a message of a different kind.

The condition for activating the promo code: the user must be authorized through steam, the profile must be open, the paid version of CS:GO (Prime CS: GO and profile rank: Private Rank 2 or +) must be purchased.
