Kohi Gyunyu (from Japanese, literally "coffee milk") consists of white, black and gray circles. The aim is to connect circles by horizontal and vertical lines. All connected circles form a group. Each group must contain exactly one gray circle and equal amounts of white and black circles. The lines must not cross other lines. White and black circles cannot be directly connected.
