Hitori Rules

Back to the game

Hitori is a japanese puzzle logic game played with a grid of squares
or cells, with each cell containing a number.

The purpose of the game is to "eliminate" cells, by coloring them in black, until there are no duplicates numbers in any row or column.

To transform the grid, it's necessary to follow these three rules :

• No row or column can have more than one occurrence of any given number.
• Black cells cannot be adjacent, although they can be diagonal to one another.
• The remaining numbered cells must be all connected to each other, horizontally or vertically.

Example of completed grid:

3	3	4	4	5
4	5	1	3	2
3	4	2	1	4
5	3	5	4	1
5	2	5	4	3
