### From 1 To X

**From 1 To X** consists of a rectangular or square grid divided into regions. Each region must be filled with each of the numbers from 1 to the number of cells in the room. Same numbers must not be orthogonally adjacent. Numbers outside the grid show the sums of the numbers in corresponding row or column.

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