Hitori is a Japanese logic puzzle game that challenges you to eliminate duplicate numbers from a grid while following three simple rules.

How to Play Hitori

Hitori is played on a square grid, this time 5x5. Each cell contains a number between 1 to 5, and the objective is to shade certain cells so that the grid meets the following conditions:

1. No duplicate numbers in any row or column – Once blacked-out, a number is no longer considered part of the grid.
2. Blacked-out cells cannot touch each other – Shaded cells must not be adjacent horizontally or vertically. If they are, shading is colored red.
3. All non-blacked-out cells must remain connected – Every unshaded cell must form a single, horizontally or vertically connected group to prevent isolated numbers.If cell is isolated, it gets light red color.

Hitori is an excellent brain-training puzzle that enhances  pattern recognition skills.
