The basic loop
Breeding starts with infrastructure, not the parent pair. Build the Breeding Farm, assign one male and one female Pal, and make sure Cake is available for the farm. Once the parents produce an egg, move it to an Egg Incubator and manage the incubation conditions until it hatches.
Why old combo lists can be wrong
Palworld 1.0 changed enough breeding data that older route recommendations should be treated as suspicious until verified. Use current 1.0 tables or this site's calculator pages when choosing parents for valuable targets.
When to use the calculator
Use a single-Pal guide when you already know the child you want. Use the calculator when you have a limited set of owned parents and want to see which listed routes are possible from your box.
Think of breeding as three connected systems
The parent pair, Cake supply, and incubation setup all have to work together. A correct parent pair still stalls without Cake, and a steady egg supply still becomes annoying if incubation is scattered or uncomfortable. Fix the whole loop before judging a route.
When to move from learning to planning
Once the basic loop works, stop reading general breeding advice and choose a target Pal. Open the target guide, compare parent availability, then use the calculator if your owned Pals matter more than a recommended route.
