+1 Strength for Eggs Mutations Tier List
Rainbow 3x, Diamond 2.5x, Gold/Hacked/Lava/Toxic 2x — ranked by Cash power and farm timing.
Tier philosophy
Mutations multiply Animal Cash (earning rate and sale value) in +1 Strength for Eggs. Higher multipliers and easier uptime rank higher. Weather-gated 2x mutations are still excellent — they are not “low tier,” they are timed tier.
Confirmed multipliers: Gold 2x, Diamond 2.5x, Rainbow 3x, Hacked 2x, Lava 2x, Toxic 2x. Spotting rules (yellow / blue / dynamic shells; weather nameplates): How to Get Mutations. Weather windows: Weather Events.
Multiplier quick table
| Mutation | Multiplier | Tier | Condition |
|---|---|---|---|
| Rainbow | 3x | S | Natural (rarest) |
| Diamond | 2.5x | A | Natural |
| Gold | 2x | B | Natural |
| Hacked | 2x | B | Hacked Weather |
| Lava | 2x | B | Lava Weather |
| Toxic | 2x | B | Toxic Weather |
S tier
Rainbow — 3x (Natural)
Rainbow is the undisputed S-tier mutation — the only 3x and the rarest natural roll. A 3x placed Animal warps the economy: Dumbbell shop rows that felt impossible start falling, rebirth cycles shorten, and offline Cash jumps hard. Any time you can roll or secure a Rainbow Egg (dynamic colors), cancel side quests, extract to the Safe Zone, hatch, place, and upgrade.
Keep Rainbow pets through rebirth planning — Rebirth keeps Dumbbells and rewards boards that already print.
A tier
Diamond — 2.5x (Natural)
Diamond is the clear A-tier pick. It is not Rainbow, but 2.5x beats every 2x mutation and still drops from natural play (blue shell). Prefer Diamond over duplicate Gold/Hacked/Lava/Toxic when board slots are tight (Best Animals, Farm Expansion).
B tier
All remaining mutations share a 2x multiplier. They rank together in B-tier for power, with situational notes:
| Mutation | Multiplier | Condition | Notes |
|---|---|---|---|
| Gold | 2x | Natural | Best “always available” 2x via yellow-shell volume farming |
| Hacked | 2x | Hacked Weather | Sprint when the sky says Hacked; read nameplates |
| Lava | 2x | Lava Weather | Same urgency as other weather muts; nameplate ID |
| Toxic | 2x | Toxic Weather | Same urgency; do not AFK the window |
B-tier still means “replace non-mutated Animals immediately.” A Gold pet is a massive upgrade over a base hatch. Weather 2x pets match Gold’s power — timing is the only difference.
Practical priority order
- Rainbow 3x (S)
- Diamond 2.5x (A)
- Any weather 2x you can finish before the event ends
- Gold 2x via steady natural grinding
- Base Animals only as fillers
When tiers mislead
- A B-tier Hacked 2x pet during Hacked weather is more valuable right now than dreaming about Rainbow.
- An S-tier Rainbow Egg you fail to carry is worth zero — Safe Zone discipline beats tier labels (Safe Zone Egg Carry).
- Multiple B-tier 2x pets can out-earn one neglected Diamond if you actually upgrade and place them (Animals Hub).
Synergy with Dumbbells and walls
Mutation Cash buys the progression S-tiers on the Dumbbells Tier List and funds Strength for walls. Biome unlocks (including Ancient Egypt) increase Egg volume for natural Rainbow/Diamond attempts. Admin Abuse windows can spike chaos but do not change the multiplier table.

Chase Rainbow 3x, respect Diamond 2.5x, and treat every weather 2x as a timed raid boss on your calendar.
Farming routes tied to each tier
S-tier Rainbow (3x) routes: Sweep every biome you can enter safely. Rainbow Eggs are the rarest natural rolls, so volume matters more than camping a single corner. Prefer paths with short returns to the Safe Zone so one contested steal does not wipe a 3x chance. If you already hold Rainbow pets, still grab extras for board upgrades or index goals.
A-tier Diamond (2.5x) routes: Treat Diamond like a softer Rainbow. Same natural spawn rules, slightly more common in practice for many players. When inventory is full, drop non-mutated Eggs before you drop Diamond. Upgrade Diamond Animals early — 2.5x scales with every Cash multiplier from Rebirth.
B-tier Gold (2x) routes: Gold is your filler farm between weather events. While training with a mid-tier Dumbbell, scan for yellow Gold Eggs and bank them. A base full of Gold pets often out-earns one neglected Diamond that never got upgraded.
B-tier weather (2x) routes: When Hacked, Lava, or Toxic skies hit, abandon Gold volume grinding. Sprint the matching mutation only — identify via nameplate text. See Weather Events for prep, and remember a weather 2x hatched now beats a theoretical Rainbow you fail to carry.
Board composition examples
- Early game: 1–2 Gold 2x pets + free group Animal + whatever Diamond 2.5x you luck into
- Mid game: Diamond core, Gold fillers, swap in weather 2x the moment they hatch
- Late game: Rainbow 3x anchors, Diamond supports, weather pets as temporary spikes while you buy Celestial Dumbbells toward Void Star
Cross-check Animal slot upgrades on the Animals Hub and Farm Expansion so high-tier mutations actually have room to sit and print offline Cash.
Frequently Asked Questions
Quick answers to the most common questions.
Why is Rainbow the only S-tier mutation?
It is the only 3x multiplier. Nothing else matches that Cash output on a placed Animal.
Are Hacked, Lava, and Toxic worse than Gold?
Same 2x power. Gold is easier to farm anytime; weather mutations are better when their event is live because you can focus sprints.
Should I sell Gold for board space if I get Diamond?
Sell the weakest earners first. Diamond usually replaces a non-mutated or weaker duplicate, not necessarily your only Gold.
Do mutations affect Strength training speed?
Indirectly — they multiply Animal Cash so you buy better Dumbbells faster. They do not replace equipping a stronger Dumbbell.
How many Rainbow pets should I keep?
Keep every Rainbow you can place. If slots are full, expand the base or replace the weakest non-Rainbow earner first.
Is Gold ever better than a weather mutation?
Same 2x power. Gold is better between events; weather mutations are better during their live window because you can focus the farm.
