About Pal Breeding Calculator

Pal Breeding Calculator is a fast, patch-accurate breeding reference for Palworld 1.0. Nothing here is guessed: every child, every parent pair and every stat comes from a structured export of the shipped game data, and the calculator is tested against the game's own breeding table before anything is published.

How the data is verified

Imported into WordPress as 299 Pals and 44,851 precomputed parent pairs, so every page renders from the stored data rather than being recalculated on each request.
A deterministic test suite re-runs known parent/child pairs on every change, so a future patch import can be checked before it goes live.

Known gaps

Element typings are not present in the current export, so element filters stay hidden.
No source publishes a per-Pal World Tree drop table yet, so that section on each Pal page stays empty until one does.
Passive skills are only listed where the game guarantees them. The inheritance odds themselves are documented in the guides, but no per-egg outcome can be predicted.
Mutation is a 1% roll per egg (3% with an Extravagant Vegetable Cake), so the calculator predicts the normal hatch and the guides explain the odds. Nothing here claims to predict the exception.
