Hitori

About Hitori

A Japanese logic puzzle where you shade cells to eliminate duplicate numbers in rows and columns.

Description provided by GameZipper.

How to play

1. Look at the grid and find any number that appears more than once in a row or column.
2. If two identical numbers are adjacent, one must be shaded and the other must not.
3. Remember: no two shaded cells can share an edge. This often forces cells to remain unshaded.
4. Make sure all unshaded cells form one connected group. If shading a cell would isolate a group, that cell must stay unshaded.
5. Continue until every row and column has no duplicate unshaded numbers, all shaded cells are non-adjacent, and all unshaded cells are connected.

Questions

What is Hitori?

Hitori is a Japanese logic puzzle played on a grid of numbers. The goal is to shade cells so that no row or column contains duplicate numbers, no two shaded cells share an edge, and all unshaded cells remain connected.

How do you play Hitori?

Click or tap a cell to shade or unshade it. The three rules are: 1) No duplicate numbers in any row or column among unshaded cells, 2) No two shaded cells share an edge, 3) All unshaded cells must form one connected group.

Is Hitori difficult?

Hitori ranges from easy (5x5 grids) to expert (8x8 grids). Start with the smaller grids and use hints if needed. The key is logical deduction — no guessing required.
