Gift codes are a feature in Bloons TD 6, Bloons TD Battles 2, and Bloons Card Storm. They were introduced to the mobile version of Bloons TD 6, Bloons TD 6+, and Bloons TD 6 NETFLIX in version 43.0, to Bloons TD Battles 2 in version 4.3 (though it was not mentioned in the update notes), and to Bloons Card Storm with the full release. Codes are distributed through official social media outlets and can be redeemed for in-game rewards. Each code can only be redeemed once, and most codes are discontinued and stop working after a certain point in time.
There are currently no known gift codes for Bloons TD Battles 2.
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.
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]
