To solve them you simply require logic, deduction and a flexible mind with numbers. Sudokus are amongst the most popular puzzle games in recent times. It combines relatively simple rules with deceptively complex solutions in the most difficult puzzles. The goal is to simply fill the grid with the correct numbers. The 9 x 9 grid is split into 9 separate 3 x 3 compartments. Each of these compartments, when solved, have the numbers 1-9 within each cell. Also, each row and each column of 9 numbers have the numbers 1-9 only once each within them when solved. You are given some clues in so far as some of the numbers are filled for you already. The more difficult the puzzle the less clues you are given. There is a unique solution to each puzzle in this book.
