Tategoi

Koi farm simulation

Tategoi is a PC koi-farm simulation set in Ojiya, Niigata, where your grandfather Kenji has left you a small farm, a notebook of unfinished plans, one pond, eight koi and a few coins. You breed fish, develop the farm and sell or show koi as you work through the notebook’s 13 goals.

Each spring, you pair a female and male koi and raise the resulting fry. Their genes pass on traits such as color, pattern, skin quality, metallic luster, sparkle, body shape and sex. A breeding forecast gives you the odds, but the fry’s eventual traits can still surprise you.
