Gift codes are a feature in Bloons TD 6, Bloons TD Battles 2, and Bloons Card Storm. This feature grants the player rewards which can be redeemed by entering a certain code. Codes are distributed through official social media outlets. Each code can only be redeemed once, and most codes are discontinued and stop working after a certain point in time.
In the Amazon Appstore, Google Play, Epic Games Store, Microsoft Store, and Steam releases, codes are redeemed in-game by going to the "Redeem Code" menu inside the settings menu. In all other releases, codes can be redeemed online from this website. Codes are not case-sensitive. If a gift code is meant to unlock a cosmetic item the player already owns, it simply equips the item instead.
Due to a bug, the ZOMG card was not included in the rewards for some players. Players who did not receive it have since received the card in their collection.[5]
