Mutations are permanent upgrades that multiply how much ore a single drill produces in Make a Drill Farm, and picking the right one decides how fast your cash climbs. As of Update 4 there are seven of them, each with a fixed multiplier, and one clear winner if your only goal is money.
Quick answer: Blackhole is the best mutation for cash at a 10x ore multiplier. To guarantee it, buy the Blackhole Mutation Cell from the Black Market for 14.6K Gems and apply it to your highest-earning drill.
All mutations and their multipliers
A mutation is baked into a drill and stacks directly on top of that drill’s base output. The higher the multiplier, the more each hit is worth, so target the strongest mutations on the drills that already earn the most.
| Mutation | Ore multiplier |
|---|---|
| Hacker | 2x |
| Golden | 3x |
| Lightning | 3x |
| Tacos | 5x |
| Magma | 5x |
| Galaxy | 7x |
| Blackhole | 10x |
Drills can also carry more than one mutation. Weather events can stack multiple mutations on the same drill, and Mutation Cells can add extra mutations on top, so a well-placed drill can end up with several multipliers at once.
Why Blackhole wins for money
At 10x, Blackhole applies the largest single multiplier in the game, ahead of Galaxy at 7x and the pair of 5x mutations, Tacos and Magma. Put it on your best drill and it multiplies your top income source rather than a weak one.
Blackhole rarely lands from natural weather rolls, so the reliable route is the Blackhole Mutation Cell at 14.6K Gems. Start saving Gems early if this is your endgame target, and hold the Cell for the highest-output drill you own so the 10x has the most to work with.
Tip: Skip the Golden Machine if you only care about the multiplier. Golden gives 3x, the same as Lightning, but the Golden Machine can destroy your drill. You can grab the same 3x safely with the Lightning Mutation Cell for just 4,000 Gems.
Three ways to get mutated drills
There are three routes to a mutated drill. Two rely on chance, and one guarantees the exact mutation you want.
| Method | How it works | Risk |
|---|---|---|
| Weather Events | Active drills on your plot have a chance to gain the current weather’s mutation. | Random, no drill loss |
| Golden Machine | Only source of the Golden mutation; pay cash for a chance at success. | Failure destroys the drill and the cash |
| Mutation Cells | Bought from the Black Market to apply a specific mutation instantly. | Guaranteed, no loss |
Weather Events
Each weather event carries its own matching mutation. While the event is active, every drill you have placed has a chance to catch that mutation. The more drills you have out, the higher your overall odds, so expand your plot and spread drills across it before big events.
Golden Machine
The large Golden Machine in the center of the map is the only way to earn the Golden mutation. It is a gamble, so only feed it a drill you can afford to lose.
Mutation Cells from the Black Market
Mutation Cells are the only guaranteed method. Buy them from the Black Market, which spawns twice every hour and stays for 10 minutes. Each Cell applies one specific mutation to the drill you choose, with no random roll and no chance of losing the drill. The mutation it adds is permanent.
How to confirm the mutation stuck
A mutated drill changes on the spot. It gains new visual effects and its listed ore output jumps by the mutation’s multiplier, so a drill that produced 92 ores per second before a Blackhole would show ten times that afterward. Check the drill’s stats to confirm the multiplier is applied before spending Gems on a second Cell.
For steady income, plant plenty of drills and stay active during weather events for free rolls, then spend Mutation Cells deliberately, reserving Blackhole for your single best drill. You can grow your farm and experiment with these mutations directly in Make a Drill Farm on Roblox.
