Welcome to Idle Zoo. Run expeditions, rescue animals, and grow habitats across themed zones. Stack passive income, watch your map come alive with little pixel visitors and critters, and fill out your collection as you discover new species and variants. EXPEDITIONS Pick an expedition, add guides, and let the timer run. When the team returns, see what you brought back—new animals, swaps when habitats are full, and coin overflow when you’re at capacity. Rush long runs if you need them back a little sooner. QUESTS Complete simple objectives, then claim coin rewards. Your active quest lineup refreshes on a new local day—so there’s always something fresh to chase without spamming the same tasks. YOUR ZOO Build habitats, wake sleepy enclosures, and explore paged habitats from the entrance to the farthest biomes. Tune the experience: compact number labels, optional auto-claim for offline earnings, and a low-power option that only eases visual motion—never your economy. Whether you play in short sessions or let the zoo run while you’re away, Idle Zoo is built to feel cozy, a little bit retro, and always ready when you return. Build. Rescue. Grow your Idle Zoo you can.
