Redeeming codes in Subterra is different than most Roblox games. To open and use the code box, players must remain at a particular place. Follow these simple steps to claim freebies:

Launch Subterra on Roblox and wait for the game to load.
Once your character has spawned, head right to find an NPC with the word "Codes" on top of his head.
Approach the NPC named Chrysos and stay on the highlighted light blue area.
When the code box opens, copy an active code from this guide and paste it into the "Enter Code" text box.
Hit the "Claim Code" button to activate the code and receive rewards.

A "Code Redeemed" success message will appear on the top of the screen, followed by a description of the obtained rewards.

Subterra codes and their importance

Roblox Subterra promo codes provide several useful resources, items, and boosts. Among the free rewards is Gold, which you can use to upgrade your Pickaxe by speaking to the blacksmith, and increase your inventory space by interacting with Emilia. Also, the resource can be used to purchase items from the "Buy" area.

Another important resource in Subterra is Chrono Shards. With the crystals, you can buy Abilities after utilizing the Card Summoning system. If you are struggling to access the feature, follow these steps:

From the spawn area, head left and follow the pathway.
Once your progress is blocked by a building, head right to find a large, revolving crystal.
If you stand close to the crystal, a drop-down menu will appear with the options "Draw Cards" and "Manage Deck."
Choose "Draw Cards." Each Summon costs 140 Shards, and you choose one of the three cards on the screen.

Both Gold and Chrono Shards can be obtained by finishing daily quests, looting chests, and completing achievements. On the other hand, Keys are rare items that unlock chests.

Subterra code troubleshooting [how to fix]

Given that Roblox promo codes for Subterra are case-sensitive, you should ideally copy-paste them into the redemption box. Typos and incorrect letter casing when manually inputting them will result in an error. Moreover, remember that each code can be claimed once in an account. The notification "Already redeemed" appears during a case of double-redemption.
