Putteria (from Japanese, "put into an area") consists of a grid divided on regions. The goal is to place a number into each region. A number is equal to the size of the region. No number may appear twice in any row or column. Cells with numbers must not be orthogonally adjacent. A cell with a cross cannot contain a number.
