Calculate the Chance of Catching a Pokémon in FireRed and LeafGreen

This tool calculates your likelihood of catching a Pokémon in Pokémon FireRed and LeafGreen. Select any Pokémon available in these games, pick your Poké Ball, fill out the rest of the information, and it will handle all the math.

FireRed and LeafGreen use the same Generation 3 formula as the Ruby and Sapphire line, adapted for the Kanto Pokédex. If you find any errors or have any issues, feel free to join our Discord server to let us know!
