Publisher's Synopsis
Suguru ("Number Blocks") is a logic puzzle invented by Naoki Inaba (Japan). The task consists of a rectangular or square grid divided into regions. Each region must be filled with each of the digits from 1 to the number of cells in the region. Cells with the same digits must not be orthogonally or diagonally adjacent. The heavy lines indicate areas, called cages, from one to five squares in size. Fill each cage with unique digits, counting up from 1. So for example a 2-square cage contains the numbers 1 and 2; and a 5-square cage contains the numbers from 1 to 5. Adjacent (touching) squares, even ones that touch diagonally, may never contain the same number.
