Pet priority by stage
Early game
Use the free Bird Pet, fill every pet slot, and hatch cheap eggs until upgrades are frequent.
Mid game
Move to higher egg tiers when current eggs rarely improve your equipped team.
Late game
Farm the highest track you can clear reliably, then roll for stronger multipliers before unlocking again.
Upgrade value order
High priority
Extra pet slots, stronger eggs, and upgrades that directly improve wins or power.
Medium priority
Luck, hatch speed, and quality-of-life options after your core team is strong.
Low priority
Cosmetic choices or convenience boosts that do not help progression.
Gamepass note
Paid upgrades are optional. For a review-friendly informational site, this guide describes value categories instead of pressuring visitors to buy anything.
