Frequently Asked Questions (FAQs)
There are three common reasons a code might fail:
Expiration: Roblox codes are time-limited. If a code has expired, it will no longer grant rewards.
Case Sensitivity: Codes must be entered exactly as they appear (including exclamation marks and capital letters).
One-Time Use: Most codes can only be redeemed once per account.
Perk and Trait Rerolls are essential items used to change the passive abilities and statistics of your towers. Rerolling allows you to maximize the efficiency and damage output of your strongest units.
New codes are typically released during major game updates, holiday events (like the current Christmas season), or when the game reaches specific milestones (like a certain number of likes or visits).
The resetModifier code is unique because it doesn’t give a reward. Instead, it is used to manually cancel any active Gold Boosts you currently have running. This is usually only used if a player wants to clear their active buffs for specific testing or strategy reasons.
