### Nurimisaki

**Nurimisaki** (from Japanese, literally *"paint a cape"*) is a logic puzzle invented by Nikoli. A rectangular or square grid contains circles in some cells; a circle may have a number inside or not. The task is to blacken some cells of a grid according to the following rules:

- White cells form a path exactly one cell wide.
- Cells with circles are always white.
- A cell with a circle must have exactly one white cell adjacent to its side.
- A white cell without a circle must have at least two orthogonally adjacent white cells.
- A number in a circle indicates how many white cells can be seen horizontally and vertically from that cell, including the cell itself.
- All the white cells must be connected horizontally or vertically.
- No
**2 x 2** cell area within the grid can have the same color.

**Cross+A** can solve puzzles from **3 x 3** to **30 x 30**.
