S+ and S Tier Skins
Cosmic Skin (S+, 100x multiplier) doubles the ceiling of even Rainbow-tier cosmetics. Applying it to anything below a Mythic drill wastes potential — you are multiplying a small base number. Reserve Cosmic Skin for your lobby showcase tile and leaderboard flex drill.
Rainbow Skin (S, 50x multiplier) is the practical endgame cosmetic most billionaires use. It turns a Mythic drill ($100K/s) into $5M/s before mutations. Combined with a Cosmic mutation (100x), you are calculating income that funds Mega Crate spam every login.
S-tier skins are rare drops and event exclusives. Budget time, not just money — you may need dozens of Mega Crate opens or a holiday event shop window to acquire them.
A and B Tier Skins
Diamond Skin (A, 15x multiplier) is the sweet spot for Ruby and Diamond-tier drills during mid-game. When you land your first Ruby Drill ($1K/s), a Diamond skin pushes effective CPS to $15K/s — enough to afford Ruby crates every login.
Gold Skin (B, 5x multiplier) is the first premium cosmetic worth pursuing. Drops are common enough from Gold and Ruby crates that most players own several by mid-game. Apply to your current best drill and move it forward as you upgrade tiles.
Bronze Skin (C, 2x multiplier) is a transitional cosmetic from early crates. Use it on Steel or Gold drills until Gold Skin replaces it. Do not invest emotional energy in Bronze — it will be obsolete within a day of active play.
D Tier and Default
Default Skin (D, 1x multiplier) is what every drill starts with. No bonus, no penalty. Replace with any earned skin as soon as inventory allows — even Bronze (2x) is a strict upgrade.
Default exists so new players understand the skin system before gambling on crate drops. The visual difference between Default and Gold Skin on the same drill model is obvious — use that feedback to confirm skin application worked.
Skin Application Priority Guide
Rule one: skin your highest base CPS drill, not your oldest. Rule two: skin before logout if you will earn offline — multipliers apply to idle income. Rule three: match skin tier to drill tier — Rainbow on Mythic, Gold on Ruby, Bronze on Steel.
Mutation stacking reminder: skin multiplier × mutation multiplier × base CPS. A Diamond skin on a Shiny mutation Ruby drill beats a Rainbow skin on a Basic drill every time because base CPS matters in the multiplication.
See our Skins item page for acquisition sources and the CPS Calculator for modeling skin swaps before you commit a legendary cosmetic to the wrong tile.

Frequently Asked Questions
What is the best skin in Make a Drill Farm?
Cosmic Skin (S+, 100x multiplier) is the highest tier, followed by Rainbow Skin (S, 50x). Apply these exclusively to your Mythic or Cosmic mutation drills for maximum CPS.
Do skins stack with mutations?
Yes. Skin multipliers and mutation multipliers multiply together. A Rainbow skin (50x) on a Cosmic mutation (100x) drill creates multiplicative stacking — not additive.
When should I apply a Gold Skin?
Apply Gold Skin (5x) to your highest CPS drill once you own an A-tier or above unit — Ruby ($1K/s) minimum. Do not skin Basic or Copper drills unless you have no other option.
How do I get higher-tier skins?
Skins drop from crates, event shops, and token stores depending on the current update. Higher-tier skins are rarer drops from Ruby, Diamond, and Mega crates plus limited event rewards.
Can I move a skin between drills?
Skin transfer mechanics depend on the current game version. Check the inventory UI for an unequip or swap option before buying a premium skin. When in doubt, commit skins to drills you will keep for weeks, not hours.
