How to redeem codes in Protect the King
Step 1: Start the Protect the King experience on Roblox and, if you are a new player, finish the in-game tutorial so that the main interface unlocks fully.
Step 2: Look at the top-left of your screen and find the button labeled for codes; select this button to open the redemption window.
Step 3: Click into the text box, carefully type or paste one of the working codes exactly as shown (matching all characters), then press the Redeem button.
Step 4: Check your Gold balance and inventory immediately after redeeming; a successful redemption increases Gold or grants the listed reward with no further action required.
Why a Protect the King code may not work
There are only a few consistent reasons a Protect the King code fails to redeem:
- The code is expired. Many codes are limited-time and stop working after a set date or after a certain period.
- The code was typed incorrectly. Extra spaces, missing characters, or incorrect capitalization can cause an error, so copying the code exactly is important.
- You are on an outdated server. In rare cases, joining a fresh server by leaving and rejoining the game can resolve issues with newly released codes.
If a code still shows as invalid after checking these points and rejoining, it should be treated as expired.
How to get more Protect the King codes
New Protect the King codes are typically released around major updates, holidays, special events, and community milestones such as like or player count goals.
To catch future codes quickly, keep an eye on the game’s official social channels, including the Protect the King Discord server, the HordeSlayerRBLX profile on X, and the Funcomofficial Roblox group, where code announcements are commonly posted.
Gold gained from these codes is immediately usable for buying potions and crafting equipment, which directly improves your ability to survive monster waves and keep the king alive.
