Tower Defense X (TDX) is one of the more difficult tower defense games on Roblox, created by GDILIVES (John Roblox). Unlike other games that shower you with codes, TDX codes are rare and usually tied to major milestones.
As of January 2026, there are only a few active codes, but they are high-value. If you are saving up for the Juggernaut or Railgunner, these will help.
💰 Top Active Codes (January 2026)
Redeem these immediately. The “John Roblox” code is the most important one for beginners as it gives a massive XP boost to help you unlock the Level 10-20 towers faster.

🛡️ Pro Tip: Spending Your Gold
Don’t Buy Basic Towers: With the 1,500+ Gold you get from these codes, do NOT buy the Shotgunner or Barracks immediately. Save your Gold to buy the Missile Trooper (Top Tier Splash Damage) or save further for the Juggernaut. The starter “Ranger” tower is actually strong enough to carry you through “Easy” mode grinding.
