Fast answer: the best Sky Zoo upgrade order
Upgrade habitat capacity first, then coin multipliers, then run stamina, and only then open new habitat slots. That order is boring but efficient. Capacity makes every captured animal more useful, multipliers shorten the time between purchases, stamina turns better control into longer routes, and new slots matter most after your existing habitats already pay back reliably.
The common beginner mistake is buying the most exciting visible upgrade instead of the upgrade that improves the next ten runs. Cowboy Safari rewards compounding income. A small capacity increase that pays every session can beat a flashy new slot that sits underfilled because you cannot yet capture enough animals to support it.
