“Hitori ni shite kure” is a Japanese logic puzzle which was published for the first time in 1990 in the famous Puzzle Communication Nikoli by a publisher specialized in puzzles and logic games

Rules

There are Hitori grids of different sizes. Our example considers 36 cell grids.

Each grid has 6 lines and 6 columns, which makes 36 cells. In each cell, there is a figure. The aim is simple: each figure cannot appear more than once in a line and a column.
If you discover the same figure two or three times on a single line or column, cross it out! Easy, isn’t it? Be careful though, to find out the figure(s) which has(ve) to be crossed out, you must follow a number of rules, which makes things more complicated…

• At the beginning of the puzzle, each cell of a grid contains one figure
• The aim is to cross out figures so that a figure does not appear more than once in a line and a column
• A crossed out figure cannot touch the cell of another one: they have to be surrounded by uncrossed figures
• All the uncrossed figures have to be connected to other uncrossed figures so that they make a single piece (you can go over all the uncrossed figures continuously)
