Subterra Codes June 2026: Updated List, Rewards and How to Redeem

Updated: June 2026

What's up, everyone! If you're as hooked as I am on breaking rocks and exploring the depths in Roblox, you know that Subterra is the perfect blend of classic Minecraft mining and chaotic Terraria platforming. But dropping down into the deeper layers without solid resources is basically asking for a respawn. Luckily, the devs over at Polyworks Studio keep dropping freebies to help us survive.

Having top-tier resources on hand, like Chrono Shards and gold, makes a huge difference when you're trying to upgrade your gear or unlock those cards that buff your gameplay. So, I took the time to gather all the active freebies for this month in one place.

Active codes today

Below is the list of all the working codes right now. Make sure to claim them quickly, because we never really know when they're going to expire and disappear from the game for good.

• 100KMEMBERS: Redeem this code to snag 420x Chrono Shards, 10x Wormhole Potions, and 10x Return by death potions.
• FEATURED: Claim 32x TNT blocks and 1x hour of double experience.
• 1YEAR: Gives you 1,400x Chrono Shards straight to your inventory.
• 30KLIKES: Activate this code and enjoy 2x hours of double experience.
• RELEASE: A classic freebie that grants you Chrono Shards and some extra Gold.

What are Chrono Shards used for?

If you're wondering why almost every code seems to give out Chrono Shards, it's because they are the main premium currency in Subterra. You can use them to purchase powerful Cards that act as permanent buffs for your character. Whether you need faster mining speed, better jump height for the Terraria-like platforming, or a higher chance to find rare ores, investing your Shards in the right Cards is the key to conquering the deepest layers of the mine.

How to redeem Subterra codes step by step

If you're new to the game or just never bothered claiming rewards before, the process is very straightforward. Unlike other Roblox games where the button is hidden in a menu, here you actually have to interact with the world:

1. Open Subterra from your app and load into the server.
2. Once you get past the tutorial and find yourself in the starting area (the surface lobby), look for the Codes NPC. You'll spot him just to the right of the spawn gate.
3. Walk up to him and step into his interaction circle.
4. A text box will pop up on your screen. Copy and paste any of the codes I dropped above.
5. Hit the Claim Code button and enjoy your loot.

Remember to type them in exactly as they appear, keeping all the capital letters, to avoid any errors from the system.

Having those Chrono Shards in your pocket is vital for buying cards that improve your mining efficiency. Plus, those free TNT blocks you get from some codes will save you precious minutes of manual digging, giving you more time to explore the high-level zones.

If you want to stay completely up to date with the game, I highly recommend checking out their official community Discord server. They post patch notes there, and you'll catch wind of new features before anyone else.

There's nothing quite like heading into the mines with an inventory full of potions and an active EXP boost. Keep digging deep and don't let the cave bugs ruin your run. Catch you in the next guide!
