The basic circular Sudoku puzzle has four concentric circular rings with the circles partitioned into 8 segments. Each of the numbers 1-8 must appear once and only once in each of the four rings and in each of the eight pairs of overlapping quarter circles. Numbers are already placed in some of the sectors, where the purpose is to guarantee a unique solution. The solution strategy for the circular Sudoku is similar to what is used in the rectangular Sudoku. The expanded circular Sudoku has five concentric rings and 10 overlapping sectors with zero added as the additional digit. This book is a collection of 120 circular Sudoku problems of varying degrees of difficulty. It will keep you busy for hours as you rise to the challenge in solving these problems.
