Subterra Codes (July 2026)

Subterra is a mining and survival game where you dig, build, and manage your stamina and inventory as you push deeper underground. The developer hands out codes every so often that give you chrono shards, potions, TNT blocks, and temporary double XP boosts, so it’s worth checking in and redeeming what’s active before it expires.

How to get more Subterra codes

New codes usually show up around milestones, like member counts, likes, favorites, or visit totals, and sometimes alongside a fresh update or hotfix. Your best bet for catching these as soon as they drop is to follow the game’s official social channels and keep an eye on the in-game announcements, since that’s where the developer tends to post them first. There’s no fixed schedule for when new codes arrive, so checking back periodically is the safest way to avoid missing free chrono shards or double XP time.

If you’re new to Subterra, spending a few minutes redeeming everything above before you head underground will give you a solid head start on shards and potions without any extra grinding.
