Suguru is an entertaining puzzle with simple rules for an involved and satisfying pure logic challenge.
A grid of cells is divided into outlined blocks containing up to five cells. Each cell in an outlined block contains a digit from 1 to n (where n is the number of cells in that block). So, a single-cell block contains the digit 1, a block of two cells contains the digits 1 and 2, and so on. The aim is to fill the grid so that no same digit is touching, not even diagonally.
