### Nanbaboru

**Nanbaboru** (*"Number Ball"*) consists of a square grid. The goal is to fill in some cells with numbers from the given range. No number may appear twice in any row or column. A cell with a circle must contain a number; a cell with a cross cannot contain a number.

**Cross+A** can solve puzzles from **3 x 3** to **9 x 9**.
