Hitori is played with a grid of squares or cells, and each cell contains a number. The object is to eliminate numbers by filling in the squares such that remaining cells do not contain numbers that appear more than once in either a given row or column. Filled-in cells cannot be horizontally or vertically adjacent, although they can be diagonally adjacent. The remaining un-filled cells must not be isolated from the rest of the grid by filled-in cells either vertically, horizontally or diagonally.
