### Gokigen Naname

**Gokigen Naname** (from Japanese, literally *"to be in a bad mood"*; also known as *"Slalom"*, *"Slant"*) is a logic puzzle invented by Nikoli. It is played on a rectangular or square grid. Circles with digits from 0 to 4 may be situated on intersections of lines inside the grid. The aim is to fill in a diagonal line in every cell. The number in each circle equals the number of lines extending from that circle. The diagonal lines must not form a closed loop.

**Cross+A** can solve puzzles from **4 x 4** to **40 x 40**.
