Yagit (from Japanese "Yagi to ookami"; literally "goat and wolf") is a logic puzzle published by Nikoli. The task consists of a rectangular or square grid with circles ("goats") and squares ("wolves") in some cells. The task is to divide the grid into regions. Each region must contain either goats or wolves (but not both) and must not be empty. The border lines of the regions start and end on the edges of the grid. Lines can only turn at black dots. Lines can cross each other except at black dots. Not all black dots must be used by border lines.
