Mine a Planet Wiki

Yes — Mine a Planet is a free-to-play Roblox experience with no pay-to-win mechanics. Drill Pieces, ores, pets, and prestige upgrades can all be earned through gameplay, and the four active codes grant 25 Drill Pieces each on top of regular grinding.

The Mythril Destroyer, Cosmic Reaper, and Astral Annihilator are tied for S-tier — they clear Nebula and Void planets the fastest thanks to their combined ore multipliers and damage formulas. For mid-game, the Solar Flare and Plasma Drill pair perfectly with the Volcano biome.

Launch the game, open the left-hand Codes button on the lobby screen, paste the active code, and press Redeem. Each code grants 25 Drill Pieces. Codes are case-sensitive and expire without warning, so redeem them as soon as you join a new patch.

Start on Earth until you craft the Copper Drill, then move to Mars and Europa for Iron Alloy and Crystal farming. Save Volcano for after you own the Titanium Spire, and only enter Nebula once you can craft the Mythril Bar — the lava mobs there destroy low-tier drills in seconds.

Wait until you reach level 25, own at least one Rare drill, and have smelted a full set of Iron Alloy. Spend your prestige points on the Ore Multiplier first for 2x drill returns, then reforge one Rare drill so it survives the reset. Rebirthing early without reforging wastes your strongest gear.

Legendary pets like Astral Cat and Cosmic Wolf come from Legendary-tier eggs. Save your Drill Pieces for the anniversary and Halloween events when drop rates spike, and equip an Epic pet before long mining sessions to double your rare drop rate.

Yes — codes expire without warning after a patch lands. The codes GOODBYESUMMER, HALLOWEEN, UPDATE1, and NEWGAMEMODE were all verified active on July 23, 2026, but earlier codes like EASTER2025 have already been retired. Always check the wiki codes page for the current valid list.

The Mythril Destroyer requires 50 Mythril Ore plus 25 Stardust to smelt a Mythril Bar, which is then used at the crafting bench to forge the drill itself. Stardust only drops in Nebula, so you must clear at least one Nebula run before the recipe becomes available.
