Calculate the chance of finding at least one shiny Pokémon from your encounter count, base odds, and the number of rolls per encounter.
Formula
const rolls = Math.max(0, inputs.encounters) * Math.max(1, inputs.rollsPerEncounter); const chance = inputs.oddsDenominator > 0 ? (1 - Math.pow(1 - 1 / inputs.oddsDenominator, rolls)) * 100 : 0; return { chance };Number of Encounters
100
Base Odds (1 in)
4,096
Rolls per Encounter
1
Send the result context for a checklist or comparison path where a first-party route is available.
