FAQs
What is the pet weight formula?
W(age) = (W_hatch / 11) × (age + 10). At age 100 a pet weighs exactly 10× its hatch weight.
How do I find hatch weight?
W_hatch = 11 × W_current / (age + 10). Use our Reverse mode to plug in current weight + age.
What are the size classes?
Small (<1kg), Normal (1–5), Huge (5–7), Titanic (7–9), Godly (9+). Size class is fixed at hatch and affects ability scaling for the pet's entire lifespan.
