Hitori - ひとり
Although the Sûdoku contest comes to an end, the Hitori contest is already on! Try again to win your tickets to Japan Expo 13th Impact thanks to your logic.
Hitori ni shite kure is a game of logic come from Japan published for the first time in 1990 in the famous Puzzle Communication Nikoli by the eponymous publisher, specialized in puzzles and logic games.
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)
