Tower Defense X: BETA Tower Defense X Codes
Community-reported promo codes for Gold, Crystals, XP, and power-ups — updated whenever new rewards drop.
Tower Defense X (TDX) on Roblox occasionally releases promo codes tied to milestones, holidays, and creator events. Codes grant Gold, Crystals, XP, or temporary power-ups that help you unlock towers and push harder difficulties. This hub lists every code players report as working right now, plus a clear expired section so you do not waste time on dead strings.
Codes are community-reported and may expire without notice. JOHN ROBLOX and the Tower Defense X group do not always announce retirements on social media, so treat any entry here as “last verified by players” rather than a permanent guarantee. When a code fails, check back after the next update or follow the official Roblox group for fresh strings.
Important: This wiki covers Tower Defense X by JOHN ROBLOX only. Do not confuse these codes with Universal Tower Defense or other unrelated TD games — strings like UTDPhase3 belong to different titles and will not work in TDX.
How to redeem codes in Tower Defense X
Redemption happens entirely in-game:
- Launch Tower Defense X: BETA on Roblox.
- Look for the megaphone / announcements icon on the right side of the screen (some layouts hide it under three dots).
- Open Codes, paste the string exactly — including spaces, punctuation, and capitalization.
- Tap Redeem and confirm the reward popup.
For screenshots, mobile quirks, and troubleshooting failed redemptions, read the full How to Redeem Codes guide.
Active codes (community-reported)
Rewards below reflect community-reported payouts verified by players — not an official developer table. Amounts may vary by account progress and patch version.
| Code | Reported rewards | Notes |
|---|---|---|
nightmare! | 100 Crystals, 2 Uber Field, 3 Emergency Crate, 2 Damage Field, 2 Range Field | Nightmare hype code — best Crystal payout |
tb4life | 1,000 Gold | Long-running community favorite |
powerupzbutworks | 1 A-10 Strafe, 10 Cash Crates, 10 Health Crates, 5 Air Strikes, 3 Stealth Sensors, 1 AC-130 Run | Large power-up bundle — see Power-ups Guide |
johnrobloxforever | 500 Gold, 1,000 XP | Creator appreciation code |
ez | 700 Gold, 20 A-10 Strikes | Community-reported on some trackers — verify in-game |
tdxiswinning | Name tag / Gold | Shattered Moon era string; reports vary |
As of August 2026 community cross-checks, the four core strings (nightmare!, tb4life, powerupzbutworks, johnrobloxforever) are the most consistently reported working codes. Treat ez and tdxiswinning as verify-before-assuming. Ignore Universal Tower Defense trackers (gems, trait rerolls) — wrong game.
If you receive a different bundle than a friend, that is normal — TDX sometimes scales payouts. Always copy-paste from this table rather than retyping.
Expired codes
These strings no longer redeem as of the latest community checks. Keep them for reference only:
| Code | Notes |
|---|---|
TDX25 | Anniversary Golden Z.E.D. / A-10 bundle — retired |
lny2026 | Lunar New Year envelopes — expired |
cookies :3 | Cookie reward string — expired |
FREEDOM | Retired event code |
atrazine | Expired promo |
johnroblox | Replaced by newer creator codes |
GiftFromXonaeAndLora | Limited gift from collaborators |
goodbyexwm | Farewell / event string — expired |
XMAS24 | Christmas 2024 seasonal code |
America250 | Unrelated / unverified burger payouts — not a TDX reward |
If a code you expect to work appears in the expired table, the developers may have rotated it during a balance pass. Watch for replacement strings after major updates.
When to check for new codes
TDX launched on November 21, 2023, and still receives content drops from JOHN ROBLOX and the Tower Defense X group. New codes typically appear around:
- Difficulty milestones (Expert / Nightmare clears trending on YouTube)
- Holiday events (Christmas, Lunar New Year, anniversaries)
- Update days when towers, maps, or modes change — especially Nightmare Mode patches
Bookmark this page and redeem as soon as a string leaks — Roblox promo codes can hit redemption caps within hours.
Spend your code rewards wisely
Gold from codes accelerates early tower purchases. Crystals unlock premium paths and cosmetics. XP pushes account level for mode access. Power-ups from strings like powerupzbutworks and nightmare! supplement Nightmare runs — read Power-ups Guide for save timing.
Instead of splurging on every dual-path branch, read Dual Path Upgrades to pick high-impact paths first, then cross-check picks on the Tier List and Nightmare Tier List.
New players should chain codes with the Getting Started checklist so bonus currency lands before your first Expert attempt.
Nightmare and power-up codes
Nightmare players benefit most from field consumables bundled in nightmare! — Uber Field, Damage Field, and Range Field align with boss burst windows in How to Beat Nightmare. Standard Nightmare queues use nightmare-only power-ups; code-granted fields may still help in other modes or during transition periods — verify in-game after each patch.
