All active Castle Defender codes to get free Gems
If you're saving up for new weapons or Pets in the Roblox game Castle Defender, we've got the latest codes that'll get you some free Gems!
Castle Defender is a fun medieval Roblox experience that tasks you with defending your castle, hiring champions, and fighting off monsters. There are even boss fights to take on!
You'll need plenty of Gems if you want to purchase new weapons or get Eggs to hatch Pets for your army. That's where codes come in handy, as redeeming them will get you a bunch of Gem rewards in the game.
Castle Defender codes
These are the Castle Defender codes listed as working as of 1st November 2026. The newer ones give you towers and defences rather than Gems, which is arguably more useful if you're struggling to hold the walls.
| Code | Reward |
| BULL | Bull |
| FIREVOLLEY | Fire Arrow Cannon (Level 1) |
| BLAZE | Flamethrower (Level 1) |
| GONG | Gong |
| FTCRIS | 100 Gems |
| OUTLOOK | 100 Gems |
FTCRIS and OUTLOOK are older Gem codes that are still listed, but they haven't been confirmed recently, so don't be surprised if they've quietly stopped working.
Expired Castle Defender codes
These codes no longer work: 1000LIKES, DVPLAYS, RELEASE, PENGUINPEEP, RUSSO, SAMANTHA.
How to redeem Castle Defender codes
Follow these instructions to claim your free rewards:
- Launch the game in Roblox
- Click the Twitter bird icon on the left-hand side of the screen
- Enter your code in the text box that appears
- Click the present icon next to it
If you've entered a valid code, you'll get your Gems immediately - now spend them wisely!
