Estimate only. Enter values to calculate.
Formula disclosure
The calculator uses hitChance = 1 - (1 - effectiveProbability) ^ rolls, where effective probability is base probability multiplied by your entered luck values. No probability cap is applied because no public source confirmed one.
FAQ
Is this calculator official?
No. It is an estimate tool based on user-entered odds and public planning presets.
What does 1 in odds mean?
A base odds value of 1,000,000 means one success per one million rolls before your luck multiplier is applied.
Why are some targets low confidence?
Exact Slime RNG odds can change and many public values need game testing.
What happens when I share the link?
The URL saves your calculator inputs (base odds, luck multipliers, roll interval, session length). Anyone who opens it gets the same inputs filled in locally; numbers are recomputed in the browser. Shared links are unofficial planning aids, not official game formulas or Roblox endorsements.
