Codes
Introduction
Mine a Planet codes are short text strings the developers drop on patch days to celebrate milestones, events, or community goals. Each code grants 25 Drill Pieces — the in-game currency used to craft new drills, unlock pet eggs, and reroll smelter bonuses. Active codes are updated within hours of every Roblox announcement; expired codes are archived for reference so you know which strings are retired. The wiki codes page is updated within hours of every Roblox announcement so you always have the freshest list of active codes. Each entry on the codes page is verified by hand and tagged with the verification date, the Drill Piece reward, and the server compatibility (public, private, or event-only). Expired codes are archived in a separate section so you can confirm whether a code you saw on social media is still active or has been retired by the developers. Bookmark this page if you redeem codes regularly.

This code is verified active as of July 23, 2026 and grants 25 Drill Pieces on top of any codes you have already redeemed this patch cycle. New accounts and returning veterans can both use this code without restriction on public or private servers.
NEWGAMEMODE
Released alongside the Underground Arena game mode — works in any private server. Released alongside the Underground Arena game mode — works in any private server. The code unlocks after you load the new game mode at least once, so hop into the Underground Arena lobby and then redeem the code for 25 Drill Pieces. This is one of the four codes currently active in the rotation as of July 23, 2026.
HALLOWEEN
Halloween event 2026 drop — pairs with the phantom drill reward track in the event page. Halloween event 2026 drop — pairs with the phantom drill reward track in the event page. This code grants 25 Drill Pieces plus a phantom drill cosmetic crate, so redeem it before the event concludes. Verified active on July 23, 2026 across both public and private servers, and it stacks with the other three active codes for a 100 Drill Piece combo.
GOODBYESUMMER
Summer farewell drop — usable alongside the other three active codes for a 100 Drill Piece combo. Summer farewell drop — usable alongside the other three active codes for a 100 Drill Piece combo. This code marks the end of the summer event and grants 25 Drill Pieces per redemption. It is the most likely of the four current codes to expire first since the autumn update will retire it as soon as the new patch lands.
Core Mechanics
Codes are redeemed from the in-game Codes board, accessed via the left-hand menu on the lobby screen. Each code is a single word or short phrase (such as UPDATE1 or GOODBYESUMMER) and is case-sensitive. Successful redemption triggers a popup, adds 25 Drill Pieces to your inventory, and updates the Codes board log so you know which codes are already claimed. Expired codes simply show a red error and consume no cooldown. Codes are tracked on the official Mine a Planet Discord and Twitter/X account, and the wiki mirrors those announcements within six hours. The in-game Codes board logs every redemption, so you can see at a glance which codes you have already claimed this patch and which ones are still on your to-do list. Some codes are tied to seasonal events (HALLOWEEN, GOODBYESUMMER) and only work during the event window. Codes that ship alongside game mode releases (NEWGAMEMODE) sometimes require you to load the new game mode at least once before redemption unlocks.
Advantages
Free Drill Pieces scale linearly with the number of codes you redeem — all four current codes together grant 100 Drill Pieces, enough for two Common Ingot smelts or one Epic pet egg. Codes also give newer players an early-game Drill Piece boost without requiring them to grind the slower starter planets. Codes that arrive alongside seasonal events often bundle other rewards on top of the standard 25 Drill Pieces.

Challenges
Codes expire without warning when a major patch lands, so the GOODBYESUMMER code in particular will be removed once the autumn update ships. Codes are also case-sensitive — typing `update1` instead of `UPDATE1` will return an error even though the code is still active. Some codes are restricted to specific servers and will not work inside private servers owned by other players.

Quick Tips
Redeem all four active codes together to bank 100 Drill Pieces before your next smelt batch — this lets you skip the slowest part of the Mars grind. This combo lets you skip the slowest part of the Mars grind since Common Ingots smelt at the same pace as Iron Alloys but require rarer ingredients. Stockpile 50 Drill Pieces ahead of time so you have a buffer for smelt queue costs and repair kits. The codes refresh on every patch day, so check the wiki once per patch cycle to stay current.
If a code returns 'expired' even though the wiki lists it as active, relaunch the game and try again — sometimes the Codes board caches old data after a server restart. The Codes board caches old data after server restarts, so the wiki status is sometimes more current than the in-game board. If the wiki lists a code as active but the in-game board rejects it, relaunch the game to refresh the cache. This is the most common cause of false 'expired' errors on otherwise-active codes, especially after a patch day.
Bookmark the wiki codes page and check it once per patch day; new codes are usually added within six hours of an official Roblox announcement. New codes are usually added within six hours of an official Roblox announcement, with the codes page updated in tandem. Bookmark the wiki codes page so you can check it the moment a new patch lands. The four current active codes (UPDATE1, NEWGAMEMODE, HALLOWEEN, GOODBYESUMMER) are worth 100 Drill Pieces combined per patch cycle, so checking once per patch pays off.
