Codes

Introduction

Codes are the fastest way to get free gems, stardust and limited units in All Star Tower Defense. Developers at Top Down Games release new codes after every update, social milestone and community event, and they expire without warning. This page tracks the active code list as of August 2026, with the exact rewards each code grants and the level requirements you need to redeem them. Redeeming is simple: open the codes menu in the lobby, paste the code and claim your reward. Because codes expire quickly, we update this page whenever a new drop appears on the official social channels or the in-game update board. If a code stops working, it has almost certainly expired — check the update notes for the newest replacement codes. Bookmark this page and check back often to avoid missing limited-unit codes that only appear for a short window.

Code Rewards Breakdown

Core Mechanics

ASTD codes are redeemed from the codes menu in the game lobby. Type or paste the code exactly as shown — codes are case-sensitive and cannot contain extra spaces. Once a code is accepted, the rewards are credited instantly to your account and the code becomes consumed. Most codes have no level requirement, but some limited-unit codes, like yickadee, require you to reach level 100 before redeeming. Rewards vary from small bundles of gems and gold to large stardust drops and exclusive limited units. The developer announces new codes on the official X/Twitter account, the community Discord and the in-game update board. Codes are time-limited: the developer removes them when the associated event or milestone ends, so a code that worked last month may be dead today. Check the status column above and re-verify in-game, because community lists can lag behind the official announcement.

Advantages

The biggest advantage of the codes system is free resources that accelerate your progression without spending Robux. Gems from codes let you pull more banners and hit the 5-star pity faster, while stardust unlocks Special Summon and Dual Starhunt banners that otherwise cost real money. Limited-unit codes give you exclusive units that may not return for months, making them the highest-value rewards in the game. Because codes are free and announced publicly, every player — even brand new ones — can claim the same boosts as veterans. For a gacha-heavy game, a steady stream of free pulls from codes is the single best way for free-to-play players to stay competitive with the meta.

Challenges

The main drawback of codes is their short lifespan. Rewards that feel generous today can expire within weeks, forcing you to check the game constantly to avoid missing a drop. Some codes are also tied to level requirements, so new players cannot redeem high-value codes like yickadee until they reach level 100. Limited-unit codes are rare and sell out quickly on the announcement channel, so they are easy to miss. Finally, a small number of codes are region-specific or tied to platform events, which means not every code works for every player. Treat codes as a bonus income stream, not a reliable long-term resource, and keep farming Story Mode as your steady source of gems and gold.
