Getting free resources in AFK Arena is a lot easier than most players think. You don’t need to spend money or grind endlessly as long as you know where to find working codes and how to redeem them the right way. These promo codes instantly give you diamonds, hero scrolls, gold, essence, and other materials that normally take days to farm.
The downside is that most of these codes don’t stay active for long, and a lot of players still try to redeem them using the old in-game method. Lilith removed that system a while back, so if you’ve been typing codes into the settings menu and wondering why they fail, that’s the reason. Everything now runs through their external redemption website.
This updated guide rounds up every active code available for December 2025, explains the correct way to redeem them, and clears up the common reasons some codes work and others don’t.
AFK Arena Redeem Codes for December 2025
What You'll Get with these Codes
You're not getting junk rewards here. The active codes for December 2025 deliver serious progression materials that normally require either premium currency or days of farming. We're talking about resources that directly impact your ability to summon new heroes, level your roster, and push through challenging content like King's Tower or Abyssal Expedition.
Here's what the current codes actually give you:
How to Redeem Your Codes
Forget everything you knew about redeeming codes in AFK Arena. The old in-game redemption box vanished when Lilith switched to their external portal system. Now you need three things: your UID, a fresh verification code, and the official redemption website.
Step 1: Grab Your UID
Launch AFK Arena and tap your profile portrait in the top-left corner. Your UID appears directly under your username as a string of numbers. Write it down or screenshot it because you'll need this for every redemption session.
Step 2: Generate Your Verification Code
Still in-game, open your Settings menu and locate the Verification Code option. Tap it to generate a six-digit code. Here's the crucial part: this code expires after two minutes. You need to move fast once you generate it.
Step 3: Hit the Redemption Portal
Navigate to https://cdkey.lilith.com/afk-global in your browser. This is Lilith's official redemption site. Enter your UID in the first field, paste your fresh verification code in the second field, then click Log In.
Step 4: Redeem and Collect
Once logged in, you'll see a gift code input box. Paste any active code from our list, hit Redeem, and check your in-game mailbox. Rewards appear instantly.

Tip
You can also log in using your email and password if you linked your account. This skips the verification code step entirely, but most players never set this up during initial registration.
Code Error Troubleshooting
Nothing’s more annoying than typing in a code and watching it fail with no real explanation. The redemption system looks simple, but a few common mistakes trip up players all the time.
The verification code timeout catches a lot of people off guard. Your verification code only stays active for about two minutes. If you generate it, get distracted, then try to redeem a few minutes later, it silently expires. The system won’t warn you, it just refuses to redeem the code. Always grab a fresh verification code right before entering anything.
Expired codes still floating around also cause a ton of headaches. Seasonal or collaboration codes disappear fast, but many websites keep old ones listed for months or years. Half of the codes you find online are usually already inactive. That’s why this guide focuses on keeping only verified working codes.
Typos and case sensitivity are classic problems too. Codes need to be entered exactly as written. One wrong letter or capitalization shift will instantly invalidate it. Copy and paste the codes directly to avoid these mistakes entirely.
Region-specific codes can be another hidden issue. Some promos only work in certain server regions, so a code from an Asia-exclusive event won’t work on a European or North American account. Most codes here work globally, but special event ones can have restrictions.
Thanks for checking out the latest AFK Arena codes. Redeem them while they’re still active and enjoy the free boosts to your team. Hope they help you push a little farther in your runs. Good luck out there, and happy summoning!
