Mine a Planet Code Rewards Guide: Drill Pieces & Pets

Mine a Planet code rewards come in a few distinct tiers, and understanding the tier system helps you prioritize which codes to redeem first and which rewards to expect from upcoming drops. Currently every active code grants exactly 25 Drill Pieces, but historical codes have ranged from 25 to 100 Drill Pieces, and the developers occasionally drop specialty codes that grant XP boosts, double drops, or even pet rewards. This guide walks through every reward tier the developers have shipped, the conditions that trigger each tier, and how to maximize the value of every code you redeem.

For the full list of currently active codes, see our Mine a Planet active codes list. For codes that have expired, see our Mine a Planet expired codes archive. This principle applies broadly across all progression stages and is one of the most reliable optimization levers in the game.

Reward Tier System

Every Mine a Planet code falls into one of four reward tiers. The tier is determined by the trigger — whether the code is tied to a seasonal event, a milestone, a patch, or a specialty announcement — and the developers have maintained this tier system consistently across the past 12 months.

The standard 25-Drill-Piece tier is by far the most common, accounting for roughly 70% of all historical codes. The bonus 50-Drill-Piece tier covers milestone events and accounts for roughly 20%. The premium 100-Drill-Piece tier is reserved for the anniversary and is the highest direct Drill Piece reward the developers have shipped.

Double XP and Double Drop Events

During major events, the developers occasionally drop specialty codes that grant double XP or double drop bonuses for a limited time window. These codes are rare — only one or two per year on average — but they can dramatically accelerate progression if redeemed at the right moment.

There are no specialty codes active right now, but the developers have historically shipped one or two per major event. To catch the next specialty code, monitor the official Discord announcements channel during major events. The exact mechanics vary slightly by patch, but the underlying principle remains consistent across all player playstyles.

Maximize the Value of Every Code You Redeem

The smartest way to use code rewards is to redeem them right before a major crafting push, not immediately upon login. The reason is that Drill Pieces are most useful when you are about to spend them on a reforge or a high-tier craft, and saving your code rewards for those moments lets you compound their value.

For example, if you redeem 100 Drill Pieces from four codes right before a Mythril Destroyer reforge campaign, you can immediately put those Drill Pieces toward the reforge cost rather than letting them sit in your wallet for hours or days. Conversely, if you redeem codes at login and then spend the Drill Pieces on random consumables, you miss the compounding effect.

Stacking Code Rewards With Active Events

Code rewards stack multiplicatively with any active in-game event bonus, which is why experienced players time their code redemptions to coincide with weekends, patch days, and seasonal events. A Drill Piece code redeemed during a 2x Drill Piece weekend event effectively doubles the reward, and a Pet Egg code redeemed during the Anniversary event unlocks an exclusive event-themed pet variant that is only available during the event window.

To stack rewards efficiently, build a redemption calendar that tracks when each event starts, when each event ends, and when each active code is likely to expire. Our code release schedule gives you the exact event timing, while our active codes list shows which codes are still redeemable. Combining both feeds gives you a clear picture of which rewards you can stack and which you should redeem immediately before they expire.

Trading Code-Only Items With Friends

Some code rewards are tradable, and the market for code-only items is a niche but profitable corner of the player-to-player trading scene. Items like the limited-edition Halloween Drill Head or the Anniversary Pet Skin rarely appear on the open market, which makes them highly sought-after by collectors and end-game players who want to flex their cosmetic collection. If you receive a tradable code reward that you do not personally need, check the trade channel for current market rates before you redeem it.

For new players, we recommend redeeming all code rewards into your own inventory rather than trading them away. The Drill Pieces and Pet Eggs are far more valuable for your own progression than any trade offer you are likely to receive in your first week. Save the trading game for when you have stabilized your own drill progression and have spare resources to allocate to the cosmetic market. For more on trading strategy, see our trade guide.

Frequently Asked Questions

What is the most valuable code reward ever shipped?

The ANNIVERSARY1 code granted 100 Drill Pieces, which is the highest direct reward. There have not been any specialty pet or legendary drill codes shipped to date. This mechanic is important to master because it compounds with every other progression lever in the game economy.

Do all codes grant Drill Pieces?

Most do, but specialty codes can grant XP boosts, double drops, or pet rewards. The current active codes (UPDATE1, NEWGAMEMODE, HALLOWEEN, GOODBYESUMMER) all grant 25 Drill Pieces. The drill selection matters because higher-tier drills persist across rebirths if bound, so a strong choice compounds over many cycles.

Can I get a code that grants a free legendary drill?

No. The developers have never shipped a code that grants a free legendary drill or free pet. All rewards to date are Drill Pieces, XP boosts, or temporary multipliers. The drill selection matters because higher-tier drills persist across rebirths if bound, so a strong choice compounds over many cycles.

Do codes expire at a specific time?

Codes expire when the developers manually remove them from the in-game Codes board. There is no scheduled expiration time. Codes survive most Roblox server restarts, but only the developers manually retiring a code will cause redemption failure. Experienced players test this approach across multiple sessions before committing to a long-term strategy based on the outcome.

Are there any codes for Robux or premium currency?

No. Mine a Planet codes do not grant Robux or any other premium currency. All rewards are in-game Drill Pieces or temporary multipliers. Yes, these exist and they follow the standard pattern documented in the patch notes; the recommended approach is to engage with them regularly.

The Hidden Value of Saving Code Rewards

Most players redeem codes the moment they log in and immediately spend the Drill Pieces on whatever is in front of them. This is a missed opportunity. Saving your code rewards for a coordinated moment — for example, right before a Mythril Destroyer reforge campaign — can multiply their effective value by 2-3x because you avoid the inefficiency of small, ad-hoc purchases.

A practical saving strategy is to keep a "code reserve" in your wallet equal to roughly 10% of your next planned major purchase. If you are about to reforge a Cosmic Reaper and the campaign will cost roughly 5 million Drill Pieces, save your code rewards until you have 500,000 Drill Pieces banked, then add the bank to the campaign budget. This discipline turns codes from a small daily trickle into a meaningful contribution to your biggest progression milestones.

How Reward Tiers Affect Your Long-Term Strategy

If the developers shift the reward tiers in a future patch — for example, dropping the standard reward from 25 to 20 Drill Pieces — the long-term impact on your progression is minimal. The difference between 25 and 20 Drill Pieces per code is roughly 20 free Drill Pieces per month, which is less than one minute of grinding on any planet. The bigger strategic factor is whether the developers introduce new reward types (pet codes, legendary drill codes) rather than tweaking existing Drill Piece amounts.

Combining this insight with active pet bonuses and prestige multipliers yields compounding benefits that accelerate overall progression.

Double-Reward Weekends and Event Stacking

During major events, the developers occasionally activate a double-reward window where redeeming a code during the event grants twice the usual payout. For example, redeeming UPDATE1 during a hypothetical double-reward weekend would grant 50 Drill Pieces instead of the usual 25. The double-reward window is announced in the official Discord and on the developer's Twitter/X, but it is not always advertised in the in-game lobby.

To catch the next double-reward weekend, follow the official Discord and watch the #announcements channel. The developers typically announce double-reward windows 24-48 hours in advance, giving you time to coordinate your next crafting push with the event window. The optimal application of this strategy depends on your current biome and active pet slot configuration.

Why Pet and Legendary Codes Are Unlikely

Players occasionally ask whether the developers will ever ship a code that grants a free pet or a free legendary drill. Based on the historical pattern, this is unlikely. The developers have consistently kept code rewards in the Drill Pieces and temporary multiplier categories, and they have not deviated from that pattern across 12+ months of code drops.

The reason is likely economic — granting free legendary drills or free pets through codes would undermine the trade economy and reduce the incentive to grind for those items. By keeping code rewards in the soft-currency Drill Pieces category, the developers reward engagement without disrupting the broader in-game economy. For a complete walkthrough of the trade economy and how items are valued, see our Mine a Planet trade guide.

How Code Rewards Compare to Other Free Sources of Drill Pieces

Codes are not the only free source of Drill Pieces in Mine a Planet. The game also offers daily login rewards, free codes from sponsored events, and occasional Roblox promo tie-ins that grant Drill Pieces through the Roblox platform itself. Compared to these other sources, codes are by far the most reliable and consistent.

Codes offer the best ratio of reward to effort, especially for active players who redeem all four codes on the same day they drop. Daily login rewards are larger in absolute terms but require 7-30 consecutive days of login to accumulate, which makes them a slower grind. Sponsored and Roblox promo tie-ins are unreliable and should be treated as bonus rewards rather than a primary Drill Piece source.

When to Spend Code Rewards on Reforges vs Crafting

The decision to spend code rewards on reforges versus crafting depends on your current progression stage. For players who have not yet crafted their first Legendary drill, code rewards are best spent on crafting — the Iron Hammer or Titanium Spire unlock gates the next planet, and that gate is more valuable than any reforge bonus. For players who already have a Legendary drill bound, code rewards are best spent on reforges — the marginal damage gain from a high Ore Multiplier roll is more impactful than any further crafting milestone.
