Kazoku ("Kazoku shashin"; from Japanese, literally "family photo") is a logic puzzle. A rectangular or square grid contains black circles in some cells; some circles may contain numbers or question marks. Also, some cells may contain numbers or question marks. The aim is to divide the grid into rectangular regions such that each region contains exactly one number or question mark. A number indicates how many black circles the region contains. The region with a question mark may contain any amount of black circles (at least one). Orthogonally adjacent circles must belong to the same region.
