How to redeem Idle Defense codes
Step 1: Open Idle Defense on Roblox and wait for the experience to finish loading. The Codes button appears on the right side of the screen.
Step 2: Press Codes to open the redemption box. Enter one code exactly as shown, including capital letters.
Step 3: Press Confirm. When the code is accepted, the game shows the reward you received and adds it immediately.
Idle Defense usually rotates codes around updates, events, and milestone celebrations. No official next code drop time is currently confirmed, so the safest move is to redeem the live list while it is still active.
