Subterra Codes (July 2026) — All Active & Expired Codes
Here are every working Subterra code for July 2026, each one verified across code sites. Redeem them for free Chrono Shards, Gold, potions, TNT, and 2x EXP boosts, the resources that speed up your descent in this Roblox mining game. Below the table you will find the exact redemption steps at the Codes NPC, where fresh codes show up, and how to make the most of each reward.
Subterra is a 2.5D procedurally generated mining game built by Polyworks Studio on place ID 16817315243. It has pulled in over 10.4 million visits and more than 268,000 favorites with a rating around 94 percent, numbers that keep climbing as the developer ships new updates. You earn Chrono Shards and Gold by playing, but codes are the fastest free shortcut to a fuller wallet, and right now there are six of them live.
Chrono Shards are the standout reward, since they are what you spend at the Chrono Crystal to draw Ability Cards. A single batch of codes can hand you well over a thousand Shards plus potions and EXP boosts, which is the difference between grinding chests for hours and building a real card setup today. We keep this page current so you never paste a dead code into the box.

All Expired Subterra Codes
Subterra retires codes quickly, usually within a few updates of release. The codes below have already expired and no longer work, so do not waste time entering them. We keep this list here so you can see the pattern and recognize when a current code is about to rotate out.
| Code | Status |
|---|---|
| 25KMEMBERS | Expired |
| UPDATE1.4.50 | Expired |
How to Redeem Codes in Subterra
Redemption happens in-game at an NPC rather than a menu button, which trips up players expecting a Codes button on the side of the screen. Find the Codes NPC first, then follow the rest of the steps.
- Launch Subterra from Roblox (place ID
16817315243) and wait until you load into the lobby. - Find the Codes NPC in the lobby, near the gate opposite the Sell area, and talk to it to open the code box.
- Type or paste a code exactly as written, matching capitalization, since codes are case-sensitive.
- Press Claim Code to redeem it.
- Your Chrono Shards, Gold, potions, TNT, or 2x EXP boost is added instantly, ready to use on your next descent.
Where Do New Codes Come From?
Polyworks Studio ties Subterra codes to clear events, which makes new ones easy to predict once you know the pattern. The strongest signals are member milestones, like milestones, and update releases, and most of them show up right in the code names.
Look at the current set and the theme is obvious. 100KMEMBERS celebrates a group milestone and 30KLIKES rewards a like milestone, while 1YEAR marks an anniversary. UPDATE and FEATURED line up with patches and the game being featured, and RELEASE dates back to launch. When the studio hits a new milestone or ships a patch, a fresh code usually follows.
The fastest places to catch them are the Polyworks Studio Roblox group, the official Discord announcements channel, and the in-game update notes. Because Subterra codes expire faster than most, redeeming the same day they drop is the safest habit, and missing a milestone code often means missing it for good.
We recheck Subterra regularly and verify each new code before it touches this page. When something stops registering or a reward amount changes, we move it to the expired table rather than leave a stale entry sitting there.
Tips for Getting the Most Out of Subterra Codes
Codes give you a head start, but how you spend the rewards decides how far that start goes. Chrono Shards are the prize here, so route them straight to the Chrono Crystal for Ability Cards rather than letting them sit. A focused card build is what carries you through the deeper, more hostile ore layers.
Save the 2x EXP boosts for a real grind session. The FEATURED and 30KLIKES codes hand out one and two hours of 2x EXP respectively, and burning those while you actively mine and level toward your next ability slot doubles the value. Redeeming them right before a focused run beats claiming them and idling in the lobby.
The potions from 100KMEMBERS are situational but worth holding. Ten Wormhole Potions and ten Return by Death Potions give you escape and recovery options on a deep descent, so hold them for a risky push into the bottom tiers rather than spending them early when the layers are still safe.
Redeem during update weeks when you can. New Subterra patches tend to arrive alongside fresh codes, so logging in right after an update means you grab the newest code before it expires and see new content on the same visit.

Frequently Asked Questions
Open Subterra and find the Codes NPC in the lobby, near the gate opposite the Sell area. Talk to the NPC to open the code box, paste the code exactly as written since codes are case-sensitive, and press Claim Code. Your rewards land instantly.
The most common reason is that the code has expired, since Subterra codes rotate out fast after updates and milestones. Other reasons are a typo or wrong capitalization, or a code you have already claimed. Each code works only once per account.
As of June 24, 2026, there are six active codes: 100KMEMBERS, 1YEAR, FEATURED, 30KLIKES, RELEASE, and UPDATE. They give Chrono Shards, Gold, potions, TNT blocks, and 2x EXP boosts.
No. Each Subterra code can be redeemed only one time per account. Once you claim it at the Codes NPC and receive the reward, entering it again returns an already-used message.
Yes, and they expire fast. The developer ties codes to updates and milestones and retires them quickly, so a code that works today may be dead within a few patches. Codes like 25KMEMBERS and UPDATE1.4.50 have already expired. Redeem any new code the same day you see it.
New codes drop in the Polyworks Studio Roblox group, the official Discord, and the game's update notes, usually tied to member milestones, like milestones, and patches. We recheck Subterra regularly and add verified codes here soon after release.
