Koi Farm is a koi breeding game. An (almost) infinite number of procedurally generated koi patterns can be bred by selectively crossbreeding koi. The Windows and Linux versions of the game are sold on Steam and itch.io, and the iOS version is sold on the app store. Koi Farm was received well and has been nominated for the Cinekid game & app award.
