How to Play Hitori

Hitori is a challenging puzzle game that requires you to eliminate cells in a grid until there are no duplicates in any row or column.

Unlike Sudoku and Kakuro, a Hitori puzzle consists of eliminating repeating numbers.

In this guide, you'll learn the basic rules of Hitori puzzles and some tips for solving the puzzles.

Gameplay

To eliminate a cell, you must turn it black by clicking on it. However, you cannot place any black cells next to each other on a side touching horizontally or vertically in the same row or column (touching diagonally is ok). You also cannot place black cells in such a way that any white cells on the board are cut off from the rest of the white cells.

You can also mark cells as definitely not eliminated by clicking on them a second time which turns into a white square. This is just for your own visual reference as both the gray cells and these white cells are treated equally as not eliminated cells. This can be useful as the game progresses to visually mark the cells you know cannot be black.
