Introducing KOI

KOI reflects a tranquil and mesmerizing experience as you embark on an introspective journey through the lens of a lone koi fish separated from its owner and is the last hope for purifying waters polluted by mankind. It’s up to you to turn the tide and guide the koi through eight artfully rendered stages that will take you into the murky as well as enchanting waters, deep below the surface.

Turmoil and Serenity on the Horizon

Become immersed in the life of the lotus pond with a spellbinding soundtrack as you guide the koi through unknown waters. Cleanse the tainted waters by maneuvering past obstacles, solving puzzles by guiding koi to open flowers and release the Light Fish, memorizing melodies hidden within deadened branches and restore the ecosystem.

Explore the Ever-Evolving Koi Pond

In the award-winning game, KOI the lotus pond takes on a life of its own as it is presented in vibrant, high definition visuals optimized for PlayStation 4. The world is waiting to be uncovered and you must help restore the ecosystem along the way. 

Peace of Mind

As the first publishing parent of Sony Computer Entertainment Shanghai (SCES), Oasis Games hopes to bring a new type of philosophy to the world with the introduction of KOI. Escape the realities of life and achieve a level of mindful satisfaction.





KOI follows the life of a koi fish who can only return to its owner by overcoming challenges and never giving up.

The once serene lotus pond and rivers have evolved into a world of uncertainty and danger where flowers no longer naturally bloom and the emissary Light Fish have become Black Fish predators, trapped within the darkness that now taints the waters. 


While navigating currents that become turbulent and the sewage filled waters underneath the surface, layers of the story can be discovered with side quests including item collection such as puzzle pieces and finding the wise Old Toad.
