A 9 x 9 square grid formation is used throughout the sudoku puzzles section, comprising 9 rows, 9 columns, and 9 inner boxes. As you probably know by now, assuming you are a SUDOKU fan, this means you can enter any number from 1 to 9 into the empty boxes.

Just check towards the back of book for all solutions, anytime you need to do so. This book is indeed a collector's item for all Sudoku experts. For the number search puzzles, use a pen, pencil, or any other convenient marker to draw a circle, rectangle, or ellipse round a number once you find it. Since the numbers are expertly hidden, if you don't mark them as you find them, they soon disappear before your eyes, meaning you have to search for them again. Tough luck! While you are engaged with solving the puzzles, you are not only having electrifying fun and purposefully entertaining yourself, but you are also subtly assimilating magnificent life-building lessons as well as developing important sensible skills of deep thinking, problem-solving, planning, and strategy along the way.
