How Palworld Breeding Works

Want the answer for a specific pair right now? Use the breeding calculator. Read on if you want to know why it says what it says.

Step 1: every Pal has a hidden breeding power

The game files give each Pal one number, stored as a “combi rank”. Lower means rarer. Jetragon sits at 70 and Anubis at 480, while Cattiva is at 2760 and Lamball at 3050. The breeding power list shows all 299.

Step 2: same species gives the same species

Two Lamball always produce a Lamball.

Step 3: the game checks the fixed combos

Some pairs skip the maths. Fuack plus Flambelle always hatches Fuack Ignis, whatever the formula would say. We found 136 of these among different-species pairs. See them all on the unique breeding combos page.

One pair depends on gender. Katress and Wixen give a different baby depending on which of them is male. The calculator shows both outcomes.

Step 4: otherwise the game averages the powers

For every other pair the game works out a target: add the two powers, add one, divide by two and round down.

target = floor((power A + power B + 1) / 2)

The baby is the Pal in the generic pool whose own power is closest to the target.

Worked example

Foxparks (2990) plus Pengullet (2960): (2990 + 2960 + 1) ÷ 2 = 2975 after rounding down. The closest Pal in the pool to 2975 is Fuack, at power 2980.

What happens on a tie

Lamball (3050) plus Cattiva (2760) gives a target of 2905. Tanzee (2900) and Daedream (2910) are equally far away. The game breaks the tie with an internal priority value, and here that picks Daedream. Tie-breaks are the place calculators most often disagree, so we verify ours against the full reference table.

What is the generic pool?

The generic pool is the set of Pals the formula is allowed to return. In our data it holds 183 of 299 Pals. The other 116 exist only through fixed combos or same-species pairs, which is why the formula can never hand you a rare variant by accident.

What breeding power does not decide

• Parent levels do not change the species.
• Passive skills and individual values are separate mechanics. Palworld 1.0 also added a chance for mutated offspring (see G-Portal’s mutation guide). Those systems are not covered here.
• Hatch time is not part of this rule.

How to plan a breed you want

1. Open the calculator’s Child → Parents tab and pick the Pal you want.
2. Add a parent you already own in the “must include” box.
3. Pick a partner from the shortlist. Fixed combos are listed first because they are certain.

Sources and how we check

Breeding powers and pair results come from the 1.0.x game files as extracted by the open-source PalCalc project (MIT licence). We rebuild the rules from those files and require that they reproduce all 44,851 recorded pair results before every release. Read the methodology for detail. Last checked 2026-09-30.
