### Hukuwall

**Hukuwall** is a logic puzzle created by Nishiyama Yukari (Japan). A rectangular or square grid contains letters in some cells. The goal is to draw a horizontal or vertical line in every empty cell. Each letter stands for a number: all the same letters must be replaced by the same number, different letters must be replaced by different numbers. A number in a cell indicates the total length of the lines that end at the edges of this cell. A line cannot connect two cells with letters. The numbers of line directions coming out of the same letter are all different.

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