Then look for single empty squares in each row and column that you can fill in. This is the most basic strategy that is the best for beginners to solve easy puzzles.

Some squares already have numbers filled in, so begin by look for missing numbers in a row, column or square. To complete the grid, every column, row and square (each containing 9 spaces) needs to be filled in with the numbers 1-9 without repeating any numbers within the row, column or square. The grid is divided into 9 separate 3 x 3 squares. Sudoku is a game played on a 9 x 9 grid where the object of the game is to fill every space with the correct number.
