PokéHeroes Sprites
This calculator is for calculating the probability of hatching a Pokémon with X good IVs (29-30), or a specific combination of IVs, on PokéHeroes.
Just tick the good IVs (silver stars) that your breeding pair has, and press calculate. You can also select a combination of good IVs that you are aiming to breed, as well as shiny/gender/nature modifiers.
It can also calculate the chance of randomly obtaining a Pokémon with IVs (not from the Daycare or Bug Hatching Contest).
Parent 1 silver IVs
Parent 2 silver IVs
Goal silver IVs (optional)
