Like many games by DigitalDNA, CastleMiner Z allows users to redeem promo codes, which unlock various features. Promo codes are only redeemable in the Xbox 360 version by default. The PC version has the "Redeem" menu item disabled; were it enabled, it would be possible to enter promo codes.
Promo codes are calculated using three pieces of input: the gamertag of the player, the ID of the promo code, and an arbitrary string of text. The input is fed into a CRC32 function. The output of this function is used to make an eight-letter promo code with a hyphen in the middle. Only the uppercase letters
AEFHKMNPRTUVWXYZ are used.
As this algorithm relies on the gamertag of each player, promo codes cannot be Shared With Other Players.
