Hitori is played on a square grid. All squares contain numbers. The aim is to identify squares with "wrong" numbers and to mark them in color or to highlight them in some other way until the following properties are met:
- In each row and in each column, each number appears only once without highlighting.
- The highlighted squares must not adjoin one another on one edge.
- The remaining white squares must be connected by edges.
Usually the given numbers clearly define the solution.
