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.

Tips for this level
- 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.
