How to play

Standard Sudoku games are played in grids with 9 blocks x 9 blocks. The columns and rows make up 9 squares that feature spaces of 3 x 3. Every single row, square, and column must be filled in with the numbers 1 to 9. The catch is that you can only use each number once – no numbers can be repeated in a row, column, or square. And that is where things become complicated!
