You do not need to understand Palworld's hidden breeding rules. Use two parents when you already have a pair, use a target when you know the Pal you want, or use the Chain Planner when you want a route from Pals in your Palbox.
Choose the right calculator mode
I have two parents
Use Calculator to see which child their egg produces.
I want a specific Pal

I know one parent

Use the Chain Planner to build a route from your local Palbox list.

Common problems
I entered a name but nothing happened
Choose a Pal from the suggestions, then use the action button or press Enter. Check the spelling if the site shows an invalid-selection message.
The Chain Planner cannot find a route
Add more starting Pals or remove one route constraint. A target may not be reachable from a very small Palbox list.
An older guide shows a different result
Check the game version, dataset version and verification status shown with the result. Older guides may use a different roster or exception table.
Do I need to upload my save?
No. Add owned Pals manually. The list is stored locally in this browser and can be removed with Clear my Palbox.
