Koi Keeper: Cozy Idle Pond

Every koi is completely one of a kind. Like a fingerprint, their pattern, colors and fins are theirs alone, even among koi of the same family. Bring an overgrown garden pond back to life, and attract wild koi from up the stream to come visit! Win them over, name them, and grow a collection like no one's ever seen!

• BRING THE GARDEN BACK. Net the neglect, clear the fallen branches and freshen the water. The more beautiful your garden, the rarer the koi who come to see it! • COLLECT 31 VARIETIES. Kohaku, Showa, Asagi and the rest, with rare forms to discover, and no two koi the same. • RAISE AND NAME THEM. Feed them by hand, earn their trust and watch them grow, some into giants. • LEARN THEIR SECRETS. The closer you grow to a koi, the more you learn about them, from their temperament to their hidden grade. Fill your Koi-Dex and learn about real koi! • PLAY YOUR WAY. Over 75+ perks to choose from and level up! YOU shape how YOUR pond grows. • MAKE THE GARDEN YOURS. Dig the pond, upgrade your equipment, plant trees, ferns, and more to create your dream pond! • VISIT FRIENDS. Add friends, visit their ponds, feed their koi! • AT YOUR OWN PACE. The pond carries on while you’re away, so there’s always something new when you come back. No ads, no energy timers, nothing to buy. Play as a guest, or sign in to play across devices.
