Sudoku is the new puzzle craze that is sweeping the globe. So what exactly is Sudoku and what makes it so addictive?
Sudoku is a numbers puzzle that is based on logic, it comprises of a 9x9 grid. This grid is sub-divided into 9 rows, 9 columns and 9 3x3 blocks.
The aim of solving Sudoku is to place all numbers from 1 to 9 in the 9x9 grid. Each new Sudoku puzzle will have certain numbers already placed in the 9x9 grid, so you have to use your elimination skills in placing the remaining numbers in the grid. Since each completed Sudoku puzzle has a unique solution this means that to solve the puzzle correctly each row, column and 3x3 block must contain only one instance of each number
