Free Gems, Stardust, and Trait Burners — sequel to the original ASTD, different code pool

A Quick Note Before You Start

All Star Tower Defense X (ASTDX) is a separate sequel to the original All Star Tower Defense — codes from one game do not work in the other. This page covers ASTDX specifically.

Active Codes

How to Redeem

Launch All Star Tower Defense X in Roblox.

Click the gear icon in the top-left corner to open Settings.

Enter the code in the text box.

Click Social Rewards to claim your items.

Note: if you're under-leveled for a code, you'll see a message saying "Your too low level to redeem this code" instead of an error — the code will just sit in the box until you clear it manually.

What Each Reward Type Means

Gems — premium currency used for Summons (unlocking new units).

Stardust — used specifically for Special Summons, a separate rarer pool.

Trait Burner — used to reroll or improve a unit's trait.

Stat Dice — used to reroll a unit's stat distribution.

Bounded Cube — a rare crafting/upgrade material.

Expired Codes (for reference)

This section fills in as codes rotate — ASTDX has released dozens tied to updates and milestones (e.g. UPDATE4, MINORDELAY, TheOverlordArrives), all now expired.

FAQ

Is there an ASTDX Trello board?

Not currently — the developers (Top Down Games) haven't published one yet, unlike some other tower defense titles.

How often do new codes come out?

Irregularly — recent checks have found stretches with no new codes, so don't expect a fixed weekly schedule.

Quick Tips for Beginners

Save Stardust for a Special Summon banner you actually want, rather than spending it on the first one you see.

Trait Burners are most valuable on your core team's strongest units — don't waste them on units you're likely to replace.

Follow the developers on X (FruitySama, GakiRBLX, NavyXFlame) for the earliest code announcements.
