How to play Hitori
- Shade cells so that no number appears twice among the white (unshaded) cells of any row or column.
- Shaded cells may never touch side by side (touching at a corner is fine).
- All the white cells must stay connected in one group, joined side by side.
- Only shade a cell to remove a repeat: a number that appears once in its row and column always stays white.

About Hitori
Every cell already has a number. Your job is to shade some of them so each row and column has no repeats, while keeping the white cells joined together.

Tips
- Start with numbers that appear only once in their row and column: circle them.
- In a row reading 4 2 4, the middle 2 stays white: if it were shaded, both 4s next to it would have to stay white, and that is a repeat.
- Watch the edges: shading must never cut the white cells into two groups.
Questions
Why must unique numbers stay white?
Shading is only for removing repeats. This rule is part of what makes each puzzle have exactly one answer, which our solver checks.
Do I need to circle white cells?
No. Circles are just a memory aid; the puzzle is solved when exactly the right cells are shaded.
