Gameplay — What Do You Actually Do?
Collect All Pets
Collect All Pets is a clean idle collector. Your equipped pets automatically attack crystals to earn Gold, which you spend hatching eggs for random pets across rarities from Common up to the top Prodigious tier. You fuse five pets of the same rarity into one a rarity higher, chase rare shiny and metallic variants, and unlock nine zones from Meadow to Grove with richer crystals. The goal is right in the name — collect all roughly 240 pets — in a cozy, satisfying snowball.
Pet Simulator 99
Pet Simulator 99 is the flagship of the pet-collecting genre and one of the biggest games on Roblox. You hatch eggs for pets, collect and upgrade an enormous roster, and push through richly produced worlds while smashing breakables for coins and diamonds. It layers in deep systems — trading, enchants, ranks, limited and exclusive pets, huge events, and real-world toy tie-ins — on top of a constant stream of high-production updates. The scale and content volume are unmatched in the genre.
Progression — How Quickly Does It Hook You?
Collect All Pets progresses through Gold income, fusing up rarities, raising Pet Score and Shiny Score to unlock zones, and an endgame Rebirth Cave and Factory. It is a focused, readable climb. Pet Simulator 99 progresses through a sprawling economy of eggs, upgrades, enchants, trading, and limited pets across constant updates and events.
