Mutation Probability Calculator — Success Chance & Expected Attempts
The Mutation Probability Calculator turns Weather effects, fully grown status and failure streaks into a single, readable success chance with expected attempts. Open it whenever you’re deciding whether to push now or wait for a better window. This mutation chance calculator also surfaces your mutation success rate in plain terms, so you can decide with confidence.
Quick Decision: Act or Wait
- Ready to act: expected attempts ≤ 2 → take the shot now.
- Likely worth it: 2 < attempts ≤ 4 → wait for stronger Weather or add 2–3 Failure Streak, then re‑run the Mutation Probability Calculator.
- Wait/save: attempts > 4 → hold for Disco/Meteor or fully grown + 3–5 streak; don’t burn runs.
How the Mutation Probability Calculator Works
In plain words: start with base chance, apply weather, then add growth and streak.
- Base chance comes from the mutation: Golden ~10%, Shiny ~8%, Crystal ~5%, Mythic ~0.05%.
- Weather applies a multiplier and a percentage bonus together (e.g., Disco ×3.0 and +300%; Meteor ×1.8 and +180%).
- Fully grown adds +10%; each failed attempt adds +2% up to +10%.
- We limit the result between 0% and 100%. Expected attempts = 1 / PFinal (1 when probability is 100%).
Weather Tips for Mutation Chance
Use these quick tips to pick the best weather for mutation chance. Re‑run the Mutation Probability Calculator before you commit attempts.
- Disco/Moonlight → Golden/Crystal often drop to ~1–2 attempts — act now.
- Meteor / Rainbow → solid options — add Fully Grown and 1–3 Streak to reduce attempts.
- Jellyfish vs. Solar → prefer Jellyfish in the same range (higher probability bonus).
- Rain / Snow / Sandstorm → decent backups — fine for mid targets, not ideal for rare tiers.
Re‑run the Mutation Probability Calculator whenever the weather shifts.
Mutation Probability Calculator Examples You Can Trust
- Golden × Disco → almost 100%; expected attempts typically = 1.
- Crystal × Disco + Fully Grown → ~0.70; add 2–3 Streak to reach ≤ ~1.3 attempts.
- Mythic × Disco + Fully Grown + Max Streak → ~20%; try a few times—don’t force it.
Strategy to Lower Expected Attempts with the Mutation Probability Calculator
Use weather as a trigger.
If Disco/Moonlight or Meteor Shower appears, the Mutation Probability Calculator is your first stop. If expected attempts drop to one or two, go for it.
Aim for practical targets.
Golden and Crystal often become efficient under mid‑to‑strong Weather. The Mutation Probability Calculator confirms it’s the right time.
Stack growth and streak smartly.
Fully grown adds +10%; each fail adds +2% up to +10%. The Mutation Probability Calculator shows thresholds clearly.
Budget with intention.
Use expected attempts from the Mutation Probability Calculator as a simple reference before committing time and currency.
Decision Recipes by Tier
Pick the recipe that fits your tier, then check attempts to succeed in the Mutation Probability Calculator and act accordingly.
Beginner — Golden / Shiny / Crystal
Target Pfinal ≥ 0.60 (expected attempts ≤ 1.7). Mid‑to‑strong Weather usually qualifies. If you’re at ~2 attempts, you’re good to go.
Mid — Enchanted / Cosmic
Strong Weather + Fully Grown first. If Pfinal < 0.40, add 2–3 Failure Streak and re‑check in the Mutation Probability Calculator.
Late — Astral / Celestial / Mythic
Strong Weather + Fully Grown + 3–5 Streak. If Pfinal < 0.20, keep waiting; the window isn’t there yet.
Re‑check the Mutation Probability Calculator after each attempt and before changing targets.
FAQ — Mutation Odds, Success Rate, and Attempts Calculator
Do higher odds always mean “go”? ▾
Not by themselves. The Mutation Probability Calculator pairs chance with expected attempts so you can weigh efficiency, timing, and budget. A high chance can still be a bad trade if the value or timing is off.
How do multiplier and bonus stack? ▾
The Mutation Probability Calculator applies Weather multiplier and percentage bonus together on the base chance, then adds Fully Grown and Streak bonuses.
Why do I see expected attempts = 1? ▾
When a strong Weather window overlaps a high‑base mutation (e.g., Disco + Golden), the Mutation Probability Calculator sets the probability to 100%. That’s your green light to act.
Jellyfish Event vs. Solar for probability bonus ▾
Jellyfish provides a better probability bonus than Solar in the same range. Flip between them in the Mutation Probability Calculator to see which delivers lower expected attempts for your target.
Make Every Attempt Count
Keep the Mutation Probability Calculator in your loop—check Weather, toggle Fully Grown, slide your Streak, and act when the numbers align. Whether you’re locking in a reliable Golden or making a calculated push for Mythic, the Mutation Probability Calculator helps you commit at the right time for the right reason.
