Child = closest_match((Parent_A_BP + Parent_B_BP) / 2)
Every Pal has a hidden Breeding Power from 10 to 1500. That's it. No RNG on species.
Why I Built This
Most breeding calculators only go one direction: A + B → C. But players usually have the opposite problem — they know what they want and need to figure out the easiest way to get there with what's in their Palbox.
So I built three modes into one tool:
- Calculator — A + B → C (44K+ combos for all 299 Pals)
- Finder — "I want Anubis. Show me every parent pair, ranked easiest first"
- Shortest Path — multi-generation chains (Shadowbeak starting from only Chikipi)
The Data Layer
The entire tool is static HTML + vanilla JS, powered by a 248-Pal JSON dataset scraped from wiki.gg. Each Pal entry includes breeding power, elements, skills, work suitability — everything needed for lookup and ranking.
The finder algorithm:
- Take the target's BP
- Calculate the required BP sum: target_BP × 2
- Loop through all 299×299 pairs, filter by sum proximity
- Rank by parent availability score (lower BP = harder to get)
No server, no API calls, loads in under 200ms.
What I'd Do Differently
- BP data validation — wiki numbers had 3 errors I caught manually. Should've built a sanity checker first.
- Mobile UX — the breeding tree graph is unusable on phone screens. Still figuring this one out.
